Carbon dioxide is a trace gas.”
[ { "content": "Title: Carbon dioxide in Earth's atmosphere Content: Carbon dioxide is an important trace gas in Earth 's atmosphere . Currently it constitutes about 0.041 % ( equal to 410 parts per million ; ppm ) by volume of the atmosphere . Despite its relatively small concentration is a potent greenhouse gas and plays a vital role in regulating Earth 's surface temperature through radiative forcing and the greenhouse effect . Reconstructions show that concentrations of in the atmosphere have varied , ranging from as high as 7,000 ppm during the Cambrian period about 500 million years ago to as low as 180 ppm during the Quaternary glaciation of the last two million years . Carbon dioxide is an integral part of the carbon cycle , a biogeochemical cycle in which carbon is exchanged between the Earth 's oceans , soil , rocks and the biosphere . Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis . Almost all other organisms depend on carbohydrate derived from photosynthesis as their primary source of energy and carbon compounds . The current episode of global warming is attributed to increasing emissions of and other greenhouse gases into Earth 's atmosphere . The global annual mean concentration of in the atmosphere has increased by more than 40 % since the start of the Industrial Revolution , from 280 ppm , the level it had for the last 10,000 years leading up to the mid-18th century , to 399 ppm as of 2015 . The present concentration is the highest in at least the past 800,000 years and likely the highest in the past 20 million years . The increase has been caused by anthropogenic sources , particularly the burning of fossil fuels and deforestation . The daily average concentration of atmospheric CO2 at Mauna Loa Observatory first exceeded 400 ppm on 10 May 2013 . It is currently rising at a rate of approximately 2 ppm/year and accelerating . An estimated 30 -- 40 % of the released by humans into the atmosphere dissolves into oceans , rivers and lakes , which contributes to ocean acidification .", "qid": "444", "docid": "Carbon_dioxide_in_Earth's_atmosphere", "rank": 1, "score": 171677 }, { "content": "Title: Carbon dioxide Content: Carbon dioxide ( chemical formula ) is a colorless gas with a density about 60 % higher than that of air ( 1.225 g/L ) that is odorless at normally encountered concentrations . Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms . It occurs naturally in Earth 's atmosphere as a trace gas at a concentration of about 0.04 percent ( 400 ppm ) by volume . Natural sources include volcanoes , hot springs and geysers , and it is freed from carbonate rocks by dissolution in water and acids . Because carbon dioxide is soluble in water , it occurs naturally in groundwater , rivers and lakes , ice caps , glaciers and seawater . It is present in deposits of petroleum and natural gas . As the source of available carbon in the carbon cycle , atmospheric carbon dioxide is the primary carbon source for life on Earth and its concentration in Earth 's pre-industrial atmosphere since late in the Precambrian has been regulated by photosynthetic organisms and geological phenomena . Plants , algae and cyanobacteria use light energy to photosynthesize carbohydrate from carbon dioxide and water , with oxygen produced as a waste product . Carbon dioxide is produced by all aerobic organisms when they metabolize carbohydrates and lipids to produce energy by respiration . It is returned to water via the gills of fish and to the air via the lungs of air-breathing land animals , including humans . Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in bread , beer and winemaking . It is produced by combustion of wood and other organic materials and fossil fuels such as coal , peat , petroleum and natural gas . It is a versatile industrial material , used , for example , as an inert gas in welding and fire extinguishers , as a pressurizing gas in air guns and oil recovery , as a chemical feedstock and in liquid form as a solvent in decaffeination of coffee and supercritical drying . It is added to drinking water and carbonated beverages including beer and sparkling wine to add effervescence . The frozen solid form of , known as `` dry ice '' is used as a refrigerant and as an abrasive in dry-ice blasting . Carbon dioxide is the most significant long-lived greenhouse gas in Earth 's atmosphere . Since the Industrial Revolution anthropogenic emissions - primarily from use of fossil fuels and deforestation - have rapidly increased its concentration in the atmosphere , leading to global warming . Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid .", "qid": "444", "docid": "Carbon_dioxide", "rank": 2, "score": 167098 }, { "content": "Title: Carbon Dioxide Information Analysis Center Content: The Carbon Dioxide Information Analysis Center ( CDIAC ) is an organization within the United States Department of Energy that has the primary responsibility for providing the US government and research community with global warming data and analysis as it pertains to energy issues .

In 1891 Marcellin Berthelot observed that heating pure carbon monoxide at about 550 ° C created small amounts of carbon dioxide but no trace of carbon , and assumed that a carbon-rich oxide was created instead , which he named `` sub-oxide '' . He assumed it was the same product obtained by electric discharge and proposed the formula C2O .

Because the introduction of a nasogastric tube is almost routine in critically ill patients , the measurement of gastric carbon dioxide can be an easy method to monitor tissue perfusion . The gastric mucosal pH is measured according to an equation that assumes that arterial bicarbonate is equal to intramucosal bicarbonate , an argument that is not always valid . Given that the gastric mucosal carbon dioxide is the directly measured value , whereas the gastric mucosal pH is the derived and possibly inaccurate value , studies that used gastric pH to monitor perfusion may be inherently flawed .

The most common puncture site is the radial artery at the wrist , but sometimes the femoral artery in the groin or other sites are used . The blood can also be drawn from an arterial catheter . An ABG test measures the blood gas tension values of arterial oxygen tension ( PaO2 ) , arterial carbon dioxide tension ( PaCO2 ) , and acidity ( pH ) .

ABG testing also has a variety of applications in other areas of medicine . Combinations of disorders can be complex and difficult to interpret , so calculators , nomograms , and rules of thumb are commonly used .

Other types can be produced from renewable energy sources such as wind turbines , solar panels , and hydroelectric power stations . Such fuels are potentially carbon-neutral because they do not result in a net increase in atmospheric greenhouse gases .

Chemists often use the phrase `` standard temperature and pressure or STP '' to convey that they are working at a temperature of 25 ° C and one atmosphere of pressure . There are three states of matter under these conditions : solids , liquids and gases . Although all three are distinct states both solids and gases can dissolve ( or disperse ) in liquids . The most commonly occurring liquid in the biosphere is water . All components of the atmosphere are capable of dissolving in water to some degree . The bulk of the stable natural components of the atmosphere are nitrogen , oxygen , carbon dioxide , gaseous water , argon and other trace gases . Materials that exist primarily in the gas phase at STP are referred to as `` volatile . '' Many natural and man-made ( anthropogenic ) materials are stable in two states at STP , earning them the title `` semi-volatile . '' A naturally occurring volatile that is sometimes found in aqueous solution is methane , water itself is semi-volatile . Man-made or anthropogenic chemicals also occur in these classes . Examples of volatile anthropogenic chemicals include the refrigerants chlorofluorocarbons ( CFCs ) and hydrofluorocarbons ( HCFCs ) . Semivolatile anthropogenics can exist as mixtures , such as petroleum distillates or as pure chemicals like trichloroethylene ( TCE ) . There is a need to analyze the dissolved gas content of aqueous solutions . Dissolved gases can directly interact with aquatic organisms or can volatilize from solution ( the latter described by Henry 's Law ) . These processes can result in exposure that , depending on the nature of the dissolved material , can have negative health effects . There is natural occurrence of various dissolved gases in groundwater and can be a measure of health for lakes , streams and rivers . Dissolved gases also occur as a result of human contamination from fuel and chlorinated spill sites . This method can be used to determine if there is natural biodegradation processes occurring in contaminated aquifers . For example , fuel hydrocarbons will break down into methane . Chlorinated solvents such as trichloroethylene , break down into ethene and chloride . Detecting these compounds can determine if biodegradation processes are occurring and possibly at what rate .

Chromatographic techniques are often useful when mixtures of analytes are present because they are capable of measuring multiple analytes during a single application . They require isolation of the analyte from the matrix they come in ( the body of the sample ) . One of the simpler techniques is to simply trap the analytes in a bubble of air above the sample ( headspace ) and inject part of that bubble directly into the instrument . This procedure is called headspace analysis .

Most fossil fuels are combusted with ambient air ( as differentiated from combustion with pure oxygen ) . Since ambient air contains about 79 volume percent gaseous nitrogen ( N2 ) , which is essentially non-combustible , the largest part of the flue gas from most fossil-fuel combustion is uncombusted nitrogen . Carbon dioxide , the next largest part of flue gas , can be as much as 10 − 25 volume percent or more of the flue gas . This is closely followed in volume by water vapor ( H2O ) created by the combustion of the hydrogen in the fuel with atmospheric oxygen . Much of the ` smoke ' seen pouring from flue gas stacks is this water vapor forming a cloud as it contacts cool air . A typical flue gas from the combustion of fossil fuels contains very small amounts of nitrogen oxides ( NOx ) , sulfur dioxide ( SO2 ) and particulate matter . The nitrogen oxides are derived from the nitrogen in the ambient air as well as from any nitrogen-containing compounds in the fossil fuel . The sulfur dioxide is derived from any sulfur-containing compounds in the fuels . The particulate matter is composed of very small particles of solid materials and very small liquid droplets which give flue gases their smoky appearance . The steam generators in large power plants and the process furnaces in large refineries , petrochemical and chemical plants , and incinerators burn considerable amounts of fossil fuels and therefore emit large amounts of flue gas to the ambient atmosphere .

It is particularly effective in reservoirs deeper than 2,500 ft. , where will be in a supercritical state , with API oil gravity greater than 22 -- 25 ° and remaining oil saturation greater than 20 % . It should also be noted that carbon dioxide flooding is not affected by the lithology of the reservoir area , but simply by the reservoir porosity and permeability , so that it is viable in both sandstone and carbonate reservoirs . By injecting CO2 into the reservoir , the viscosity of any hydrocarbon will be reduced and hence will be easier to sweep to the production well . As an oil field matures and production rates decline , there is growing incentive to intervene and attempt to increase oil output utilizing tertiary recovery techniques ( also termed improved or enhanced oil recovery ) . Petroleum engineers assess available options for increasing well productivity , options that include chemical injection , thermal/steam injection , and CO2 injection . Based on data-gathering and computer simulations , the most optimal enhanced oil-recovery technique to maximize well-productivity is determined . To increase the rate of oil production , the pressure within the reservoir must be increased . In CO2 flooding , the first step is injection of water into the reservoir , which will cause the reservoir pressure to increase . Once the reservoir has sufficient pressure , the next step is to pump the CO2 down through the same injection wells . The CO2 gas is forced into the reservoir to come into contact with the oil . This creates a miscible zone that can be moved more easily to the production well . Normally the CO2 injection is alternated with water injection and the water acts to sweep the oil towards the production zone . CO2 flooding is the second most common tertiary recovery technique and is used in facilities around the world .

One carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases . There are two markets for carbon offsets . In the larger , compliance market , companies , governments , or other entities buy carbon offsets in order to comply with caps on the total amount of carbon dioxide they are allowed to emit . This market exists in order to achieve compliance with obligations of Annex 1 Parties under the Kyoto Protocol , and of liable entities under the EU Emission Trading Scheme . In 2006 , about $ 5.5 billion of carbon offsets were purchased in the compliance market , representing about 1.6 billion metric tons of CO2e reductions . In the much smaller , voluntary market , individuals , companies , or governments purchase carbon offsets to mitigate their own greenhouse gas emissions from transportation , electricity use , and other sources . For example , an individual might purchase carbon offsets to compensate for the greenhouse gas emissions caused by personal air travel . Many companies ( see list ) offer carbon offsets as an up-sell during the sales process so that customers can mitigate the emissions related with their product or service purchase ( such as offsetting emissions related to a vacation flight , car rental , hotel stay , consumer good , etc. ) . In 2008 , about $ 705 million of carbon offsets were purchased in the voluntary market , representing about 123.4 million metric tons of CO2e reductions . Some fuel suppliers in the UK offer fuel which has been carbon offset such as Fuel dyes . Offsets are typically achieved through financial support of projects that reduce the emission of greenhouse gases in the short - or long-term . The most common project type is renewable energy , such as wind farms , biomass energy , or hydroelectric dams . Others include energy efficiency projects , the destruction of industrial pollutants or agricultural byproducts , destruction of landfill methane , and forestry projects . Some of the most popular carbon offset projects from a corporate perspective are energy efficiency and wind turbine projects . Carbon offsetting has gained some appeal and momentum mainly among consumers in western countries who have become aware and concerned about the potentially negative environmental effects of energy-intensive lifestyles and economies . The Kyoto Protocol has sanctioned offsets as a way for governments and private companies to earn carbon credits that can be traded on a marketplace . The protocol established the Clean Development Mechanism ( CDM ) , which validates and measures projects to ensure they produce authentic benefits and are genuinely `` additional '' activities that would not otherwise have been undertaken . Organizations that are unable to meet their emissions quota can offset their emissions by buying CDM-approved Certified Emissions Reductions . Emissions from burning fuel , such as red diesel , has pushed one UK fuel supplier to create a carbon offset fuel named Carbon Offset Red Diesel . Offsets may be cheaper or more convenient alternatives to reducing one 's own fossil-fuel consumption . However , some critics object to carbon offsets , and question the benefits of certain types of offsets . Due diligence is recommended to help businesses in the assessment and identification of `` good quality '' offsets to ensure offsetting provides the desired additional environmental benefits , and to avoid reputational risk associated with poor quality offsets . Offsets are viewed as an important policy tool to maintain stable economies and to improve sustainability .

Since GHG emissions caused by the combustion of fossil fuels are closely related to the carbon content of the respective fuels , a tax on these emissions can be levied by taxing the carbon content of fossil fuels at any point in the product cycle of the fuel . Carbon tax offers social and economic benefits . It is a tax that increases revenue without significantly altering the economy while simultaneously promoting objectives of climate change policy . The objective of a carbon tax is to reduce the harmful and unfavorable levels of carbon dioxide emissions , thereby decelerating climate change and its negative effects on the environment and human health . Carbon taxes offer a potentially cost-effective means of reducing greenhouse gas emissions . From an economic perspective , carbon taxes are a type of Pigovian tax . They help to address the problem of emitters of greenhouse gases not facing the full social cost of their actions . Carbon taxes can be a regressive tax , in that they may directly or indirectly affect low-income groups disproportionately . The regressive impact of carbon taxes could be addressed by using tax revenues to favour low-income groups . A number of countries have implemented carbon taxes or energy taxes that are related to carbon content . Most environmentally related taxes with implications for greenhouse gas emissions in OECD countries are levied on energy products and motor vehicles , rather than on emissions directly . Opposition to increased environmental regulation such as carbon taxes often centers on concerns that firms might relocate and/or people might lose their jobs . It has been argued , however , that carbon taxes are more efficient than direct regulation and may even lead to higher employment ( see footnotes ) .

Among such technologies are bio-energy with carbon capture and storage , biochar , direct air capture , ocean fertilization and enhanced weathering . CDR is a different approach than removing CO2 from the stack emissions of large fossil fuel point sources , such as power stations . The latter reduces emission to the atmosphere but can not reduce the amount of carbon dioxide already in the atmosphere . As CDR removes carbon dioxide from the atmosphere , it creates negative emissions , offsetting emissions from small and dispersed point sources such as domestic heating systems , airplanes and vehicle exhausts . It is regarded by some as a form of climate engineering , while other commentators describe it as a form of carbon capture and storage or extreme mitigation . Whether CDR would satisfy common definitions of `` climate engineering '' or `` geoengineering '' usually depends upon the scale on which it would be undertaken . The likely need for CDR has been publicly expressed by a range of individuals and organizations involved with climate change issues , including IPCC chief Rajendra Pachauri , the UNFCCC executive secretary Christiana Figueres , and the World Watch Institute .

The carbon neutrality concept may be extended to include other greenhouse gases ( GHG ) measured in terms of their carbon dioxide equivalence ( e ) -- the impact a GHG has on the atmosphere expressed in the equivalent amount of CO2 . The term `` climate neutral '' reflects the broader inclusiveness of other greenhouse gases in climate change , even if CO2 is the most abundant , encompassing other greenhouse gases regulated by the Kyoto Protocol , namely : methane ( CH4 ) , nitrous oxide ( N2O ) , hydrofluorocarbons ( HFC ) , perfluorocarbons ( PFC ) , and sulphur hexafluoride ( SF6 ) . Both terms are used interchangeably throughout this article . The best practice for organizations and individuals seeking carbon neutral status entails reducing and/or avoiding carbon emissions first so that only unavoidable emissions are offset . Carbon neutral status is commonly achieved in two ways : Balancing carbon dioxide released into the atmosphere from burning fossil fuels , with renewable energy that creates a similar amount of useful energy , so that the carbon emissions are compensated , or alternatively using only renewable energies that do n't produce any carbon dioxide ( also called a post-carbon economy ) . Carbon offsetting by paying others to remove or sequester 100 % of the carbon dioxide emitted from the atmosphere -- for example by planting trees -- or by funding ` carbon projects ' that should lead to the prevention of future greenhouse gas emissions , or by buying carbon credits to remove ( or ` retire ' ) them through carbon trading .

Originally created as a by-product of the coking process , its use developed during the 19th and early 20th centuries tracking the industrial revolution and urbanization . By-products from the production process included coal tars and ammonia , which were important chemical feedstock for the dye and chemical industry with a wide range of artificial dyes being made from coal gas and coal tar . Facilities where the gas was produced were often known as a manufactured gas plant ( MGP ) or a gasworks . The discovery of large reserves of natural gas in the North Sea off the Scottish coast during the early 1960s led to the expensive conversion or replacement of most of the UK 's gas cookers and gas heaters , except in Northern Ireland , from the late 1960s onwards . The production process is distinct , both physically and chemically , from that used to create a range of gaseous fuels known variously as manufactured gas , syngas , hygas , Dowson gas , and producer gas . These gases are made by partial combustion of a wide variety of feed stocks in some mixture of air , oxygen , or steam , to reduce the latter to hydrogen and carbon dioxide although some destructive distillation may also occur .", "qid": "444", "docid": "Coal_gas", "rank": 88, "score": 95014 }, { "content": "Title: Carbaminohemoglobin Content: Carbaminohemoglobin ( or carbaminohaemoglobin , also known as carbhaemoglobin and carbohaemoglobin ) is a compound of hemoglobin and carbon dioxide , and is one of the forms in which carbon dioxide exists in the blood . 30 % of carbon dioxide is carried in blood this way ( 60 % carried in blood as bicarbonate -LSB- hydrogen carbonate -RSB- , 10 % carried as free CO2 , in solution , or plasma ) .", "qid": "444", "docid": "Carbaminohemoglobin", "rank": 89, "score": 94953 }, { "content": "Title: Bomb pulse Content: The bomb pulse is the sudden increase of carbon-14 ( 14C ) in the Earth 's atmosphere due to the hundreds of aboveground nuclear bombs tests started in 1945 and intensified between 1950 until 1963 when the Limited Test Ban Treaty was signed by the United States , the Soviet Union and Great Britain .

The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas . Natural gas is a fossil fuel used as a source of energy for heating , cooking , and electricity generation . It is also used as fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals . Fossil fuel based natural gas is a non-renewable resource . Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates . Petroleum is another resource and fossil fuel found in close proximity to and with natural gas . Most natural gas was created over time by two mechanisms : biogenic and thermogenic . Biogenic gas is created by methanogenic organisms in marshes , bogs , landfills , and shallow sediments . Deeper in the earth , at greater temperature and pressure , thermogenic gas is created from buried organic material . In petroleum production gas is often burnt as flare gas . The World Bank estimates that over 150 cubic kilometers of natural gas are flared or vented annually .

As well as the economic cost of lost commodities , fugitive emissions contribute to air pollution and climate change . A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide , or 12 per cent of all greenhouse gases emitted by the sector . Venting of natural gas , flaring , accidental releases and storage losses accounted for an additional 38 per cent . Fugitive emissions present other risks and hazards . Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities . In situations where large amounts of flammable liquids and gases are contained under pressure , leaks also increase the risk of fire and explosion . Leaks from pressurized process equipment generally occur through valves , pipe connections , mechanical seals , or related equipment . Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks . Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks , fugitive emissions can be a significant proportion of total emissions . Though the quantities of leaked gases may be small , gases that have serious health or environmental impacts can cause a significant problem . To minimize and control leaks at process facilities operators carry out regular leak detection and repair activities . Routine inspections of process equipment with gas detectors can be used to identify leaks and estimate the leak rate in order to decide on appropriate corrective action . Proper routine maintenance of equipment reduces the likelihood of leaks . Because of the technical difficulties and costs of detecting and quantifying actual fugitive emissions at a site or facility , and the variability and intermittent nature of emission flow rates , bottom-up estimates based on standard emission factors are generally used for annual reporting purposes . New technologies are under development that could revolutionize the detection and monitoring of fugitive emissions . One technology , known as differential absorption lidar ( DIAL ) , can be used to remotely measure concentration profiles of hydrocarbons in the atmosphere up to several hundred meters from a facility . DIAL has been used for refinery surveys in Europe for over 15 years . A pilot study carried out in 2005 using DIAL found that actual emissions at a refinery were fifteen times higher than those previously reported using the emission factor approach . The fugitive emissions were equivalent to 0.17 % of the refinery throughput .

In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century .

Future climate change and associated impacts will differ from region to region around the globe .

Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years .

One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming .

Greenhouse gases in the atmosphere radiate energy , some of which is directed to the surface and lower atmosphere .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world .

It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect . This scientific opinion is expressed in synthesis reports , by scientific bodies of national or international standing , and by surveys of opinion among climate scientists . Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys .

Because carbon dioxide is soluble in water , it occurs naturally in groundwater , rivers and lakes , ice caps , glaciers and seawater . It is present in deposits of petroleum and natural gas . As the source of available carbon in the carbon cycle , atmospheric carbon dioxide is the primary carbon source for life on Earth and its concentration in Earth 's pre-industrial atmosphere since late in the Precambrian has been regulated by photosynthetic organisms and geological phenomena .

Carbon dioxide is produced by all aerobic organisms when they metabolize carbohydrates and lipids to produce energy by respiration . It is returned to water via the gills of fish and to the air via the lungs of air-breathing land animals , including humans . Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in bread , beer and winemaking . It is produced by combustion of wood and other organic materials and fossil fuels such as coal , peat , petroleum and natural gas . It is a versatile industrial material , used , for example , as an inert gas in welding and fire extinguishers , as a pressurizing gas in air guns and oil recovery , as a chemical feedstock and in liquid form as a solvent in decaffeination of coffee and supercritical drying .

Carbon neutral status is commonly achieved in two ways : Balancing carbon dioxide released into the atmosphere from burning fossil fuels , with renewable energy that creates a similar amount of useful energy , so that the carbon emissions are compensated , or alternatively using only renewable energies that do n't produce any carbon dioxide ( also called a post-carbon economy ) . Carbon offsetting by paying others to remove or sequester 100 % of the carbon dioxide emitted from the atmosphere -- for example by planting trees -- or by funding ` carbon projects ' that should lead to the prevention of future greenhouse gas emissions , or by buying carbon credits to remove ( or ` retire ' ) them through carbon trading . While carbon offsetting is often used alongside energy conservation measures to minimize energy use , the practice is criticized by some . The concept may be extended to include other greenhouse gases measured in terms of their carbon dioxide equivalence .

Once air becomes saturated , water will condense out to form clouds , dew or films of water over leaves . It is this last instance that makes VPD important for greenhouse regulation . If a film of water forms on a plant leaf , it becomes far more susceptible to rot . On the other hand , as the VPD increases , the plant needs to draw more water from its roots . In the case of cuttings , the plant may dry out and die . For this reason the ideal range for VPD in a greenhouse is from 0.45 kPa to 1.25 kPa , ideally sitting at around 0.85 kPa . As a general rule , most plants grow well at VPDs of between 0.8 and 0.95 kPa . A series of membership functions for defining optimality degree of VPD at different light condition and growth stages of greenhouse tomato can be found in the work of Shamshiri . In ecology , it is the difference between the actual water vapour pressure and the saturation water vapour pressure at a particular temperature .

This format was followed in subsequent Assessment Reports . The executive summary of the policymakers ' summary of the WG I report includes : We are certain of the following : there is a natural greenhouse effect ... ; emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases : CO2 , methane , CFCs and nitrous oxide . These increases will enhance the greenhouse effect , resulting on average in an additional warming of the Earth 's surface . The main greenhouse gas , water vapour , will increase in response to global warming and further enhance it . We calculate with confidence that : ... CO2 has been responsible for over half the enhanced greenhouse effect ; long-lived gases would require immediate reductions in emissions from human activities of over 60 % to stabilise their concentrations at today 's levels ... Based on current models , we predict : under -LSB- BAU -RSB- increase of global mean temperature during the -LSB- 21st -RSB- century of about 0.3 oC per decade ( with an uncertainty range of 0.2 to 0.5 oC per decade ) ; this is greater than that seen over the past 10,000 years ; under other ... scenarios which assume progressively increasing levels of controls , rates of increase in global mean temperature of about 0.2 oC -LSB- to -RSB- about 0.1 oC per decade . There are many uncertainties in our predictions particularly with regard to the timing , magnitude and regional patterns of climate change , due to our incomplete understanding of : sources and sinks of GHGs ; clouds ; oceans ; polar ice sheets . Our judgement is that : global mean surface air temperature has increased by 0.3 to 0.6 oC over the last 100 years ... ; The size of this warming is broadly consistent with predictions of climate models , but it is also of the same magnitude as natural climate variability . Thus the observed increase could be largely due to this natural variability ; alternatively this variability and other human factors could have offset a still larger human-induced greenhouse warming . The unequivocal detection of the enhanced greenhouse effect is not likely for a decade or more . under the IPCC business as usual emissions scenario , an average rate of global mean sea level rise of about 6 cm per decade over the next century ( with an uncertainty range of 3 -- 10 cm per decade ) , mainly due to thermal expansion of the oceans and the melting of some land ice .

Carbon offsets are measured in metric tons of carbon dioxide-equivalent ( CO2e ) and may represent six primary categories of greenhouse gases : carbon dioxide , methane ( CH4 ) , nitrous oxide ( N2O ) , perfluorocarbons ( PFCs ) , hydrofluorocarbons ( HFCs ) , and sulfur hexafluoride ( SF6 ) . One carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases . There are two markets for carbon offsets . In the larger , compliance market , companies , governments , or other entities buy carbon offsets in order to comply with caps on the total amount of carbon dioxide they are allowed to emit . This market exists in order to achieve compliance with obligations of Annex 1 Parties under the Kyoto Protocol , and of liable entities under the EU Emission Trading Scheme . In 2006 , about $ 5.5 billion of carbon offsets were purchased in the compliance market , representing about 1.6 billion metric tons of CO2e reductions . In the much smaller , voluntary market , individuals , companies , or governments purchase carbon offsets to mitigate their own greenhouse gas emissions from transportation , electricity use , and other sources . For example , an individual might purchase carbon offsets to compensate for the greenhouse gas emissions caused by personal air travel . Many companies ( see list ) offer carbon offsets as an up-sell during the sales process so that customers can mitigate the emissions related with their product or service purchase ( such as offsetting emissions related to a vacation flight , car rental , hotel stay , consumer good , etc. ) . In 2008 , about $ 705 million of carbon offsets were purchased in the voluntary market , representing about 123.4 million metric tons of CO2e reductions . Some fuel suppliers in the UK offer fuel which has been carbon offset such as Fuel dyes . Offsets are typically achieved through financial support of projects that reduce the emission of greenhouse gases in the short - or long-term . The most common project type is renewable energy , such as wind farms , biomass energy , or hydroelectric dams . Others include energy efficiency projects , the destruction of industrial pollutants or agricultural byproducts , destruction of landfill methane , and forestry projects . Some of the most popular carbon offset projects from a corporate perspective are energy efficiency and wind turbine projects . Carbon offsetting has gained some appeal and momentum mainly among consumers in western countries who have become aware and concerned about the potentially negative environmental effects of energy-intensive lifestyles and economies . The Kyoto Protocol has sanctioned offsets as a way for governments and private companies to earn carbon credits that can be traded on a marketplace . The protocol established the Clean Development Mechanism ( CDM ) , which validates and measures projects to ensure they produce authentic benefits and are genuinely `` additional '' activities that would not otherwise have been undertaken . Organizations that are unable to meet their emissions quota can offset their emissions by buying CDM-approved Certified Emissions Reductions . Emissions from burning fuel , such as red diesel , has pushed one UK fuel supplier to create a carbon offset fuel named Carbon Offset Red Diesel . Offsets may be cheaper or more convenient alternatives to reducing one 's own fossil-fuel consumption . However , some critics object to carbon offsets , and question the benefits of certain types of offsets . Due diligence is recommended to help businesses in the assessment and identification of `` good quality '' offsets to ensure offsetting provides the desired additional environmental benefits , and to avoid reputational risk associated with poor quality offsets . Offsets are viewed as an important policy tool to maintain stable economies and to improve sustainability . One of the hidden dangers of climate change policy is unequal prices of carbon in the economy , which can cause economic collateral damage if production flows to regions or industries that have a lower price of carbon -- unless carbon can be purchased from that area , which offsets effectively permit , equalizing the price .", "qid": "446", "docid": "Carbon_offset", "rank": 59, "score": 129635 }, { "content": "Title: North American Carbon Program Content: The North American Carbon Program ( NACP ) is one of the major elements of the Strategic Plan for the U.S. Climate Change Science Program .

Since GHG emissions caused by the combustion of fossil fuels are closely related to the carbon content of the respective fuels , a tax on these emissions can be levied by taxing the carbon content of fossil fuels at any point in the product cycle of the fuel . Carbon tax offers social and economic benefits . It is a tax that increases revenue without significantly altering the economy while simultaneously promoting objectives of climate change policy . The objective of a carbon tax is to reduce the harmful and unfavorable levels of carbon dioxide emissions , thereby decelerating climate change and its negative effects on the environment and human health . Carbon taxes offer a potentially cost-effective means of reducing greenhouse gas emissions . From an economic perspective , carbon taxes are a type of Pigovian tax . They help to address the problem of emitters of greenhouse gases not facing the full social cost of their actions . Carbon taxes can be a regressive tax , in that they may directly or indirectly affect low-income groups disproportionately . The regressive impact of carbon taxes could be addressed by using tax revenues to favour low-income groups . A number of countries have implemented carbon taxes or energy taxes that are related to carbon content . Most environmentally related taxes with implications for greenhouse gas emissions in OECD countries are levied on energy products and motor vehicles , rather than on emissions directly . Opposition to increased environmental regulation such as carbon taxes often centers on concerns that firms might relocate and/or people might lose their jobs .

This creates air pollution , including nitrous oxides and particulates , and is a significant contributor to global warming through emission of carbon dioxide , for sector . By subsector , road transport is the largest contributor to global warming . Environmental regulations in developed countries have reduced the individual vehicle 's emission ; however , this has been offset by an increase in the number of vehicles , and more use of each vehicle . Some pathways to reduce the carbon emissions of road vehicles considerably have been studied . Energy use and emissions vary largely between modes , causing environmentalists to call for a transition from air and road to rail and human-powered transport , and increase transport electrification and energy efficiency . The transportation sector is a major source of greenhouse gas emissions ( GHGs ) in the United States . An estimated 30 percent of national GHGs are directly attributable to transportation -- and in some regions , the proportion is even higher . Transportation methods are the greatest contributing source of GHGs in the U.S. , accounting for 47 percent of the net increase in total U.S. emissions since 1990 . Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl , which can consume natural habitat and agricultural lands .

Most fossil fuels are combusted with ambient air ( as differentiated from combustion with pure oxygen ) . Since ambient air contains about 79 volume percent gaseous nitrogen ( N2 ) , which is essentially non-combustible , the largest part of the flue gas from most fossil-fuel combustion is uncombusted nitrogen . Carbon dioxide , the next largest part of flue gas , can be as much as 10 − 25 volume percent or more of the flue gas . This is closely followed in volume by water vapor ( H2O ) created by the combustion of the hydrogen in the fuel with atmospheric oxygen . Much of the ` smoke ' seen pouring from flue gas stacks is this water vapor forming a cloud as it contacts cool air . A typical flue gas from the combustion of fossil fuels contains very small amounts of nitrogen oxides ( NOx ) , sulfur dioxide ( SO2 ) and particulate matter . The nitrogen oxides are derived from the nitrogen in the ambient air as well as from any nitrogen-containing compounds in the fossil fuel . The sulfur dioxide is derived from any sulfur-containing compounds in the fuels . The particulate matter is composed of very small particles of solid materials and very small liquid droplets which give flue gases their smoky appearance . The steam generators in large power plants and the process furnaces in large refineries , petrochemical and chemical plants , and incinerators burn considerable amounts of fossil fuels and therefore emit large amounts of flue gas to the ambient atmosphere . The table below presents the total amounts of flue gas typically generated by the burning of fossil fuels such as natural gas , fuel oil and coal .

It is returned to water via the gills of fish and to the air via the lungs of air-breathing land animals , including humans . Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in bread , beer and winemaking . It is produced by combustion of wood and other organic materials and fossil fuels such as coal , peat , petroleum and natural gas .

Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph . Because the GWP of a greenhouse gas depends directly on its infrared spectrum , the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change .", "qid": "447", "docid": "Global_warming_potential", "rank": 22, "score": 110871 }, { "content": "Title: Space-based measurements of carbon dioxide Content: Space-based measurements of carbon dioxide are used to help answer questions about Earth 's carbon cycle .

Carbon pricing usually takes the form either of a carbon tax or a requirement to purchase permits to emit , generally known as cap-and-trade , but also called `` allowances '' . Carbon pricing solves the economic problem that , a known greenhouse gas , is what economics calls a negative externality -- a detrimental product that is not priced ( charged for ) by any market . As a consequence of not being priced , there is no market mechanism responsive to the costs of CO2 emitted . The standard economic solution to problems of this type , first proposed by Arthur Pigou in 1920 , is for the product - in this case , CO2 emissions - to be charged at a price equal to the monetary value of the damage caused by the emissions . This should result in the economically optimal ( efficient ) amount of CO2 emissions . Many practical concerns mar the theoretical simplicity of this picture : for example , the exact monetary damage caused by a tonne of CO2 is uncertain . The economics of carbon pricing is much the same for taxes and cap-and-trade . Both prices are efficient ; they have the same social cost and the same effect on profits if permits are auctioned . However , some economists argue that caps prevent non-price policies , such as renewable energy subsidies , from reducing carbon emissions , while carbon taxes do not .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation . In some areas , policies designed to address global warming may contribute positively towards other development objectives .

At the surface of the oceans towards the poles , seawater becomes cooler and more carbonic acid is formed as CO2 becomes more soluble . This is coupled to the ocean 's thermohaline circulation which transports dense surface water into the ocean 's interior ( see the entry on the solubility pump ) . Although the deep ocean contains much more dissolved inorganic carbon than the surface ocean , the concentration is only 15 % higher in the deep ocean as compared to the surface ocean due to the higher volume of the deep ocean . In upper ocean areas of high biological productivity , organisms convert reduced carbon to tissues , or carbonates to hard body parts such as shells and tests . These are , respectively , oxidized ( soft-tissue pump ) and redissolved ( carbonate pump ) at lower average levels of the ocean than those at which they formed , resulting in a downward flow of carbon ( see entry on the biological pump ) . The flux or absorption of carbon dioxide into the world 's oceans is influenced by the presence of widespread viruses within ocean water , that infect many species of bacteria . The resulting bacterial deaths spawn a sequence of events that lead to greatly enlarged respiration of carbon dioxide , enhancing the role of the oceans as a carbon sink . The balance of dissolved inorganic carbon ( DIC ) : dissolved organic carbon ( DOC ) : particle organic carbon is about 2000:38:1 . The CaCO3 counter pump increases the partial pressure of CO2 in the ocean , thus leading to higher outgasing of carbon dioxide . Higher ocean temperatures lead to stronger layering , thus less mixing and less capacity for thermohaline circulation to bring carbon into lower ocean layers . The weathering of silicate rock ( see carbonate-silicate cycle ) . Carbonic acid reacts with weathered rock to produce bicarbonate ions . The bicarbonate ions produced are carried to the ocean , where they are used to make marine carbonates . Unlike dissolved CO2 in equilibrium or tissues , which decay , weathering does not move the carbon into a reservoir from which it can readily return to the atmosphere . Much remains to be learned about the cycling of carbon in the deep ocean . For example , a recent discovery is that larvacean mucus houses ( commonly known as `` sinkers '' ) are created in such large numbers that they can deliver as much carbon to the deep ocean as has been previously detected by sediment traps . Because of their size and composition , these houses are rarely collected in such traps , so most biogeochemical analyses have erroneously ignored them . The amount of dissolved inorganic carbon in the ocean is significantly higher in the deep layer ( below 300 m depth ) .

Whereas biofuels are derived from recent-growth organic matter and are typically harvested , as with logging of forests and cutting of corn , fossil fuels are of prehistoric origin and are extracted from the ground , the principal fossil fuels being oil , coal , and natural gas . From an economic policy perspective , an important distinction between biofuels and fossil fuels is that only the former is sustainable or renewable . Whereas we can continue to obtain energy from biofuels indefinitely in principle , the Earth 's reserves of fossil fuels was determined millions of years ago and is therefore fixed as far as our foreseeable future is concerned . The great variability in the ease of extraction of fossil fuels however makes its endgame scenario one of increasing prices over one or more centuries rather than of abrupt exhaustion . From the perspective of climate and ecology , biofuels and fossil fuels have in common that they contribute to the production of atmospheric carbon dioxide , which has emerged in recent decades as the fastest-changing greenhouse gas , whose principal impacts are global warming and ocean acidification . However biofuels actively participate in the carbon cycle today by photosynthesizing carbon dioxide , unlike fossil fuels whose participation was long ago , and can therefore in principle bring atmospheric CO2 into an equilibrium not possible with the continued use of fossil fuel . But in practice photosynthesis is a slow process , and the additional fuel produced by artificial methods of accelerating it such as application of fertilizer tends to be offset by the energy consumed by the accelerating processes , to a degree currently under active debate .

The order of magnitude uncertainty in current volcanic/tectonic carbon outgassing makes answering fundamental questions about the global carbon budget virtually impossible . In particular , one fundamental unknown is if carbon transferred to the Earth 's interior via subduction is efficiently recycled back to the Earth 's mantle lithosphere , crust and surface environment through volcanic and tectonic degassing , or if significant quantities of carbon are being subducted into the deep mantle . Because significant quantities of mantle carbon are also released through Mid-Ocean Ridge volcanism , if carbon inputs and outputs at subduction zone settings are in balance , then the net effect will be an imbalance in the global carbon budget , with carbon being preferentially removed from the Earth 's deep interior and redistributed to more shallow reservoirs including the mantle lithosphere , crust , hydrosphere and atmosphere .

The Earth is much cooler and so radiates heat back away from itself at much longer wavelengths , mostly in the infrared range . The idealized greenhouse model is based on the fact that certain gases in the Earth 's atmosphere , including carbon dioxide and water vapour , are transparent to the high-frequency , high-energy solar radiation , but are much more opaque to the lower frequency infrared radiation leaving the surface of the earth . Thus heat is easily let in , but is partially trapped by these gases as it tries to leave . Rather than get hotter and hotter , Kirchhoff 's law of thermal radiation says that the gases of the atmosphere also have to re-emit the infrared energy that they absorb , and they do so , also at long infrared wavelengths , both upwards into space as well as downwards back towards the Earth 's surface . In the long-term , thermal equilibrium is reached when all the heat energy arriving on the planet is leaving again at the same rate . In this idealized model , the greenhouse gases cause the surface of the planet to be warmer than it would be without them , in order for the required amount of heat energy finally to be radiated out into space from the top of the atmosphere . The greenhouse effect can be illustrated with an idealized planet . This is a common `` textbook model '' : the planet will have a constant surface temperature Ts and an atmosphere with constant temperature Ta . For diagrammatic clarity , a gap can be depicted between the atmosphere and the surface . Alternatively , Ts could be interpreted as a temperature representative of the surface and the lower atmosphere , and Ta could be interpreted as the temperature of the upper atmosphere .

This creates air pollution , including nitrous oxides and particulates , and is a significant contributor to global warming through emission of carbon dioxide , for sector . By subsector , road transport is the largest contributor to global warming . Environmental regulations in developed countries have reduced the individual vehicle 's emission ; however , this has been offset by an increase in the number of vehicles , and more use of each vehicle . Some pathways to reduce the carbon emissions of road vehicles considerably have been studied . Energy use and emissions vary largely between modes , causing environmentalists to call for a transition from air and road to rail and human-powered transport , and increase transport electrification and energy efficiency . The transportation sector is a major source of greenhouse gas emissions ( GHGs ) in the United States . An estimated 30 percent of national GHGs are directly attributable to transportation -- and in some regions , the proportion is even higher . Transportation methods are the greatest contributing source of GHGs in the U.S. , accounting for 47 percent of the net increase in total U.S. emissions since 1990 . Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl , which can consume natural habitat and agricultural lands . By reducing transportation emissions globally , it is predicted that there will be significant positive effects on Earth 's air quality , acid rain , smog and climate change .

It should also be noted that carbon dioxide flooding is not affected by the lithology of the reservoir area , but simply by the reservoir porosity and permeability , so that it is viable in both sandstone and carbonate reservoirs . By injecting CO2 into the reservoir , the viscosity of any hydrocarbon will be reduced and hence will be easier to sweep to the production well . As an oil field matures and production rates decline , there is growing incentive to intervene and attempt to increase oil output utilizing tertiary recovery techniques ( also termed improved or enhanced oil recovery ) . Petroleum engineers assess available options for increasing well productivity , options that include chemical injection , thermal/steam injection , and CO2 injection . Based on data-gathering and computer simulations , the most optimal enhanced oil-recovery technique to maximize well-productivity is determined . To increase the rate of oil production , the pressure within the reservoir must be increased . In CO2 flooding , the first step is injection of water into the reservoir , which will cause the reservoir pressure to increase . Once the reservoir has sufficient pressure , the next step is to pump the CO2 down through the same injection wells . The CO2 gas is forced into the reservoir to come into contact with the oil . This creates a miscible zone that can be moved more easily to the production well . Normally the CO2 injection is alternated with water injection and the water acts to sweep the oil towards the production zone . CO2 flooding is the second most common tertiary recovery technique and is used in facilities around the world .

Seawater is slightly basic ( meaning pH > 7 ) , and the process in question is a shift towards pH-neutral conditions rather than a transition to acidic conditions ( pH < 7 ) . Ocean alkalinity is not changed by the process , or may increase over long time periods due to carbonate dissolution . An estimated 30 -- 40 % of the carbon dioxide from human activity released into the atmosphere dissolves into oceans , rivers and lakes . To achieve chemical equilibrium , some of it reacts with the water to form carbonic acid . Some of these extra carbonic acid molecules react with a water molecule to give a bicarbonate ion and a hydronium ion , thus increasing ocean acidity ( H + ion concentration ) . Between 1751 and 1996 surface ocean pH is estimated to have decreased from approximately 8.25 to 8.14 , representing an increase of almost 35 % in H + ion concentration in the world 's oceans . Earth System Models project that within the last decade ocean acidity exceeded historical analogues and in combination with other ocean biogeochemical changes could undermine the functioning of marine ecosystems and disrupt the provision of many goods and services associated with the ocean . Increasing acidity is thought to have a range of potentially harmful consequences for marine organisms , such as depressing metabolic rates and immune responses in some organisms , and causing coral bleaching . By increasing the presence of free hydrogen ions , each molecule of carbonic acid that forms in the oceans ultimately results in the conversion of two carbonate ions into bicarbonate ions . This net decrease in the amount of carbonate ions available makes it more difficult for marine calcifying organisms , such as coral and some plankton , to form biogenic calcium carbonate , and such structures become vulnerable to dissolution .

The dry reforming reaction may be represented by : CO2 + CH4 → 2 H2 + 2 CO Thus , two greenhouse gases are consumed and useful chemical building blocks , hydrogen and carbon monoxide , are produced . A challenge to the commercialization of this process is that the hydrogen that is produced tends to react with the carbon dioxide . For example , the following reaction typically proceeds with a lower activation energy than the dry reforming reaction itself : CO2 + H2 → H2O + CO Typical catalysts are noble metals , Ni or Ni alloys .

The greenhouse effect is caused by greenhouse gases that absorb sunlight . Energy from the sun that reaches Earth is either retained or sent into space . Greenhouse gases in Earth 's atmosphere such as carbon dioxide , methane , and water vapor absorb energy which cause a blanketing effect that warms the earth .

As well as the economic cost of lost commodities , fugitive emissions contribute to air pollution and climate change . A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide , or 12 per cent of all greenhouse gases emitted by the sector . Venting of natural gas , flaring , accidental releases and storage losses accounted for an additional 38 per cent . Fugitive emissions present other risks and hazards . Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities . In situations where large amounts of flammable liquids and gases are contained under pressure , leaks also increase the risk of fire and explosion . Leaks from pressurized process equipment generally occur through valves , pipe connections , mechanical seals , or related equipment . Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks . Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks , fugitive emissions can be a significant proportion of total emissions . Though the quantities of leaked gases may be small , gases that have serious health or environmental impacts can cause a significant problem . To minimize and control leaks at process facilities operators carry out regular leak detection and repair activities . Routine inspections of process equipment with gas detectors can be used to identify leaks and estimate the leak rate in order to decide on appropriate corrective action . Proper routine maintenance of equipment reduces the likelihood of leaks . Because of the technical difficulties and costs of detecting and quantifying actual fugitive emissions at a site or facility , and the variability and intermittent nature of emission flow rates , bottom-up estimates based on standard emission factors are generally used for annual reporting purposes .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

Many impacts of climate change have already been observed , including glacier retreat , changes in the timing of seasonal events ( e.g. , earlier flowering of plants ) , and changes in agricultural productivity . Future effects of climate change will vary depending on climate change policies and social development . The two main policies to address climate change are reducing human greenhouse gas emissions ( climate change mitigation ) and adapting to the impacts of climate change . Geoengineering is another policy option . Near-term climate change policies could significantly affect long-term climate change impacts . Stringent mitigation policies might be able to limit global warming ( in 2100 ) to around 2 ° C or below , relative to pre-industrial levels . Without mitigation , increased energy demand and extensive use of fossil fuels might lead to global warming of around 4 ° C.

In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years . There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere .

This system is made up of earth 's water , ice , atmosphere , rocky crust , and all living things . Quantifying changes in these amounts is required to accurately model the Earth 's climate . Received radiation is unevenly distributed over the planet , because the Sun heats equatorial regions more than polar regions . Energy is absorbed by the atmosphere , hydrosphere , and lithosphere , and , in a process informally described as Earth 's heat engine , the solar heating is redistributed through evaporation of surface water , convection , rainfall , winds , and ocean circulation . When the incoming solar energy is balanced by an equal flow of heat to space , the Earth is said to be in radiative equilibrium and under that condition , global temperatures will be stable . Disturbances of Earth 's radiative equilibrium , such as an increase of greenhouse gases , will change global temperatures in response . However , Earth 's energy balance and heat fluxes depend on many factors , such as atmospheric composition ( mainly aerosols and greenhouse gases ) , the albedo ( reflectivity ) of surface properties , cloud cover and vegetation and land use patterns . Changes in surface temperature due to Earth 's energy budget do not occur instantaneously , due to the inertia of the oceans and the cryosphere .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world .

The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation .

The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect . This scientific opinion is expressed in synthesis reports , by scientific bodies of national or international standing , and by surveys of opinion among climate scientists . Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys .

A main one is the temperature rise , and according to the report '' Our Changing Climate '' , the global warming that has been going on for the past 50 years is primarily due to human activities ( Walsh , et al. 20 ) . Since 1895 , the U.S. average temperature has increased from 1.3 ° F to 1.9 ° F , with most of the increase taken place since around year 1970 ( Walsh , et al. 20 ) .", "qid": "449", "docid": "Environmental_issue", "rank": 71, "score": 80143 }, { "content": "Title: Runaway climate change Content: Runaway climate change or runaway global warming is hypothesized to follow a tipping point in the climate system , after accumulated climate change initiates a reinforcing positive feedback . This is thought to cause the climate to rapidly change until it reaches a new stable condition . These phrases may be used with reference to concerns about rapid global warming . Some astronomers use the expression runaway greenhouse effect to describe a situation where the climate deviates catastrophically and permanently from the original state -- as happened on Venus .

It involves denial , dismissal , unwarranted doubt or contrarian views which strongly depart from the scientific opinion on climate change , including the extent to which it is caused by humans , its impacts on nature and human society , or the potential of adaptation to global warming by human actions . Some deniers do endorse the term , but others often prefer the term climate change skepticism , although this is a misnomer for those who deny anthropogenic global warming . In effect , the two terms form a continuous , overlapping range of views , and generally have the same characteristics : both reject , to a greater or lesser extent , mainstream scientific opinion on climate change . Climate change denial can also be implicit , when individuals or social groups accept the science but fail to come to terms with it or to translate their acceptance into action . Several social science studies have analyzed these positions as forms of denialism . Campaigning to undermine public trust in climate science has been described as a `` denial machine '' of industrial , political and ideological interests , supported by conservative media and skeptical bloggers in manufacturing uncertainty about global warming . In the public debate , phrases such as climate skepticism have frequently been used with the same meaning as climate denialism . The labels are contested : those actively challenging climate science commonly describe themselves as `` skeptics '' , but many do not comply with common standards of scientific skepticism and , regardless of evidence , persistently deny the validity of human caused global warming . Although scientific opinion on climate change is that human activity is extremely likely to be the primary driver of climate change , the politics of global warming have been affected by climate change denial , hindering efforts to prevent climate change and adapt to the warming climate . Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none . Of the world 's countries , the climate change denial industry is most powerful in the United States . Since January 2015 , the United States Senate Committee on Environment and Public Works has been chaired by oil lobbyist and climate change denier Jim Inhofe . Inhofe is notorious for having called climate change `` the greatest hoax ever perpetrated against the American people '' and for having claimed to have debunked the alleged hoax in February 2015 when he brought a snowball with him in the Senate chamber and tossed it across the floor . Organised campaigning to undermine public trust in climate science is associated with conservative economic policies and backed by industrial interests opposed to the regulation of emissions . Climate change denial has been associated with the fossil fuels lobby , the Koch brothers , industry advocates and libertarian think tanks , often in the United States . More than 90 % of papers sceptical on climate change originate from right-wing think tanks . The total annual income of these climate change counter-movement-organizations is roughly $ 900 million . Between 2002 and 2010 , nearly $ 120 million ( # 77 million ) was anonymously donated via the Donors Trust and Donors Capital Fund to more than 100 organisations seeking to undermine the public perception of the science on climate change . In 2013 the Center for Media and Democracy reported that the State Policy Network ( SPN ) , an umbrella group of 64 U.S. think tanks , had been lobbying on behalf of major corporations and conservative donors to oppose climate change regulation . Since the late 1970s , oil companies have published research broadly in line with the standard views on global warming . Despite this , oil companies organized a climate change denial campaign to disseminate public disinformation for several decades , a strategy that has been compared to the organized denial of the hazards of tobacco smoking by tobacco companies .", "qid": "449", "docid": "Climate_change_denial", "rank": 74, "score": 79876 }, { "content": "Title: Effects of global warming on Sri Lanka Content: Sri Lanka is an equatorial island of 65,610 km2 which hosts many diverse endemic species , and is considered to be a biodiversity hotspot .

As a result , GCM output can not be used for local impact studies . To overcome this problem downscaling methods are developed to obtain local-scale weather and climate , particularly at the surface level , from regional-scale atmospheric variables that are provided by GCMs . Two main forms of downscaling technique exist . One form is dynamical downscaling , where output from the GCM is used to drive a regional , numerical model in higher spatial resolution , which therefore is able to simulate local conditions in greater detail . The other form is statistical downscaling , where a statistical relationship is established from observations between large scale variables , like atmospheric surface pressure , and a local variable , like the wind speed at a particular site . The relationship is then subsequently used on the GCM data to obtain the local variables from the GCM output . In 1997 , Wilby and Wigley divided downscaling into four categories : regression methods , weather pattern-based approaches , stochastic weather generators , which are all statistical downscaling methods , and limited-area modeling .

Carbon dioxide is an integral part of the carbon cycle , a biogeochemical cycle in which carbon is exchanged between the Earth 's oceans , soil , rocks and the biosphere . Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis . Almost all other organisms depend on carbohydrate derived from photosynthesis as their primary source of energy and carbon compounds . The current episode of global warming is attributed to increasing emissions of and other greenhouse gases into Earth 's atmosphere . The global annual mean concentration of in the atmosphere has increased by more than 40 % since the start of the Industrial Revolution , from 280 ppm , the level it had for the last 10,000 years leading up to the mid-18th century , to 399 ppm as of 2015 . The present concentration is the highest in at least the past 800,000 years and likely the highest in the past 20 million years . The increase has been caused by anthropogenic sources , particularly the burning of fossil fuels and deforestation . The daily average concentration of atmospheric CO2 at Mauna Loa Observatory first exceeded 400 ppm on 10 May 2013 . It is currently rising at a rate of approximately 2 ppm/year and accelerating .

In turn , the absolute sea level during this time period stood at elevations much higher than the present level . Continental encroachment of seawater formed widespread shallow seas , including expanses of epeiric seas . An increase in surface area between shallow , warm epeiric seawater and the atmosphere permits higher evaporation rates and more precipitation at various latitudes , producing a more temperate global climate .

It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide . A GWP is calculated over a specific time interval , commonly 20 , 100 , or 500 years . GWP is expressed as a factor of carbon dioxide ( whose GWP is standardized to 1 ) .

User related choices such as the time horizon can greatly affect the numerical values obtained for carbon dioxide equivalents . For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph .

One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years .

The greenhouse effect is caused by greenhouse gases that absorb sunlight . Energy from the sun that reaches Earth is either retained or sent into space . Greenhouse gases in Earth 's atmosphere such as carbon dioxide , methane , and water vapor absorb energy which cause a blanketing effect that warms the earth . Aerosols such as black carbon also catalyze the warming effect as they are unreflective and absorb energy from the sun supplementing greenhouse gases in the warming effect . These combined factors are warming the Earth 's land as well as the oceans . Many fish species possess a certain range of water temperature that they are able to tolerate which is causing species to migrate to different areas where the water temperature is livable .

The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years .

The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon .

Carbon taxes offer a potentially cost-effective means of reducing greenhouse gas emissions . From an economic perspective , carbon taxes are a type of Pigovian tax . They help to address the problem of emitters of greenhouse gases not facing the full social cost of their actions . Carbon taxes can be a regressive tax , in that they may directly or indirectly affect low-income groups disproportionately . The regressive impact of carbon taxes could be addressed by using tax revenues to favour low-income groups . A number of countries have implemented carbon taxes or energy taxes that are related to carbon content . Most environmentally related taxes with implications for greenhouse gas emissions in OECD countries are levied on energy products and motor vehicles , rather than on emissions directly . Opposition to increased environmental regulation such as carbon taxes often centers on concerns that firms might relocate and/or people might lose their jobs . It has been argued , however , that carbon taxes are more efficient than direct regulation and may even lead to higher employment ( see footnotes ) . Many large users of carbon resources in electricity generation , such as the United States , Russia , and China , are resisting carbon taxation .", "qid": "450", "docid": "Carbon_tax", "rank": 46, "score": 111261 }, { "content": "Title: Low-carbon economy Content: A low-carbon economy ( LCE ) , low-fossil-fuel economy ( LFFE ) , or decarbonised economy is an economy based on low carbon power sources that therefore has a minimal output of greenhouse gas ( GHG ) emissions into the biosphere , but specifically refers to the greenhouse gas carbon dioxide .

It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth . The temperature at the surface is 740 K ( 467 ° C , 872 ° F ) , and the pressure is 93 bar ( 9.3 MPa ) , roughly the pressure found 900 m underwater on Earth . The Venusian atmosphere supports opaque clouds made of sulfuric acid , making optical Earth-based and orbital observation of the surface impossible . Information about the topography has been obtained exclusively by radar imaging . Aside from carbon dioxide , the other main component is nitrogen . Other chemical compounds are present only in trace amounts . Mikhail Lomonosov was the first person to hypothesize the existence of an atmosphere on Venus based on his observation of the transit of Venus of 1761 in a small observatory near his house in Saint Petersburg , Russia . Aside from the very surface layers , the atmosphere is in a state of vigorous circulation . The upper layer of troposphere exhibits a phenomenon of super-rotation , in which the atmosphere circles the planet in just four Earth days , much faster than the planet 's sidereal day of 243 days . The winds supporting super-rotation blow at a speed of 100 m/s ( ~ 360 km/h or 220 mph ) or more . Winds move at up to 60 times the speed of the planet 's rotation , while Earth 's fastest winds are only 10 % to 20 % rotation speed . On the other hand , the wind speed becomes increasingly slower as the elevation from the surface decreases , with the breeze barely reaching the speed of 10 km/h ( 2.8 m/s ) on the surface . Near the poles are anticyclonic structures called polar vortices . Each vortex is double-eyed and shows a characteristic S-shaped pattern of clouds . Above there is an intermediate layer of mesosphere which separates the troposphere from the thermosphere . The thermosphere is also characterized by strong circulation , but very different in its nature - the gases heated and partially ionized by sunlight in the sunlit hemisphere migrate to the dark hemisphere where they recombine and downwell . Unlike Earth , Venus lacks a magnetic field . Its ionosphere separates the atmosphere from outer space and the solar wind . This ionised layer excludes the solar magnetic field , giving Venus a distinct magnetic environment . This is considered Venus 's induced magnetosphere . Lighter gases , including water vapour , are continuously blown away by the solar wind through the induced magnetotail . It is speculated that the atmosphere of Venus up to around 4 billion years ago was more like that of the Earth with liquid water on the surface . A runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of the levels of other greenhouse gases . Despite the harsh conditions on the surface , the atmospheric pressure and temperature at about 50 km to 65 km above the surface of the planet is nearly the same as that of the Earth , making its upper atmosphere the most Earth-like area in the Solar System , even more so than the surface of Mars . Due to the similarity in pressure and temperature and the fact that breathable air ( 21 % oxygen , 78 % nitrogen ) is a lifting gas on Venus in the same way that helium is a lifting gas on Earth , the upper atmosphere has been proposed as a location for both exploration and colonization .

The reaction is also used to produce graphite for radiocarbon dating with Accelerator Mass Spectrometry . The Bosch reaction is being investigated for use in maintaining space station life support .

Carbon rift theory states that this ultimately disrupts the natural carbon cycle and that this `` rift '' has adverse effects on nearly every aspect of life . Many of the specifics regarding how this metabolic carbon rift interacts with capitalism are proposed by Brett Clark and Richard York in a 2005 article titled `` Carbon Metabolism : Global capitalism , climate change , and the biospheric rift '' in the journal Theory and Society . Researchers such as Jean P. Sapinski of the University of Oregon claim that , despite increased interest in closing the carbon rift , it is projected that as long as capitalism continues , there is little hope of reducing the rift . Both deforestation and the emission of greenhouse gases have been linked to increased atmospheric CO2 levels . Carbon rift theory states that these are the result of human production through capitalistic systems . There are proposed solutions to climate change such as geoengineering proposed in the December 2015 Paris Agreement . However , some argue that the capitalist mode of production is at fault for the emission of greenhouse gas and that solutions must be found to this issue before climate change itself can be addressed .

That charge , called a carbon price , is the amount that must be paid for the right to emit one tonne of CO2 into the atmosphere . Carbon pricing usually takes the form either of a carbon tax or a requirement to purchase permits to emit , generally known as cap-and-trade , but also called `` allowances '' . Carbon pricing solves the economic problem that , a known greenhouse gas , is what economics calls a negative externality -- a detrimental product that is not priced ( charged for ) by any market . As a consequence of not being priced , there is no market mechanism responsive to the costs of CO2 emitted . The standard economic solution to problems of this type , first proposed by Arthur Pigou in 1920 , is for the product - in this case , CO2 emissions - to be charged at a price equal to the monetary value of the damage caused by the emissions . This should result in the economically optimal ( efficient ) amount of CO2 emissions . Many practical concerns mar the theoretical simplicity of this picture : for example , the exact monetary damage caused by a tonne of CO2 is uncertain . The economics of carbon pricing is much the same for taxes and cap-and-trade . Both prices are efficient ; they have the same social cost and the same effect on profits if permits are auctioned . However , some economists argue that caps prevent non-price policies , such as renewable energy subsidies , from reducing carbon emissions , while carbon taxes do not . Others argue that an enforced cap is the only way to guarantee that carbon emissions will actually be reduced ; a carbon tax will not prevent those who can afford to do so from continuing to generate emissions .

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction .

Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) .

Climate engineering is an umbrella term for measures that mainly fall into two types : carbon dioxide removal and solar radiation management . Carbon dioxide removal addresses the cause of global warming by removing one of the greenhouse gases ( carbon dioxide ) from the atmosphere . Solar radiation management attempts to offset effects of greenhouse gases by causing the Earth to absorb less solar radiation . Climate engineering approaches are sometimes viewed as additional potential options for limiting global warming , alongside mitigation and adaptation . There is substantial agreement among scientists that climate engineering can not substitute for climate change mitigation . Some approaches might be used as accompanying measures to sharp cuts in greenhouse gas emissions . Given that all types of measures for addressing climate change have economic , political , or physical limitations , some climate engineering approaches might eventually be used as part of an ensemble of measures . Research on costs , benefits , and various types of risks of most climate engineering approaches is at an early stage and their understanding needs to improve to judge their adequacy and feasibility . Almost all research into solar radiation management has consisted of computer modelling or laboratory tests , and an attempt to move to outdoor experimentation was controversial . Some carbon dioxide removal practices , such as planting of trees and bio-energy with carbon capture and storage projects , are underway . Their scalability to effectively affect global climate is , however , debated . Ocean iron fertilization has been given small-scale research trials , sparking substantial controversy . Most experts and major reports advise against relying on climate engineering techniques as a simple solution to global warming , in part due to the large uncertainties over effectiveness and side effects . However , most experts also argue that the risks of such interventions must be seen in the context of risks of dangerous global warming . Interventions at large scale may run a greater risk of disrupting natural systems resulting in a dilemma that those approaches that could prove highly ( cost - ) effective in addressing extreme climate risk , might themselves cause substantial risk . Some have suggested that the concept of engineering the climate presents a so-called `` moral hazard '' because it could reduce political and public pressure for emissions reduction , which could exacerbate overall climate risks ; others assert that the threat of climate engineering could spur emissions cuts .

The aim is to prevent the release of large quantities of into the atmosphere ( from fossil fuel use in power generation and other industries ) . It is a potential means of mitigating the contribution of fossil fuel emissions to global warming and ocean acidification . Although has been injected into geological formations for several decades for various purposes , including enhanced oil recovery , the long term storage of is a relatively new concept . The first commercial example was the Weyburn-Midale Carbon Dioxide Project in 2000 . Other examples include SaskPower 's Boundary Dam and Mississippi Power 's Kemper Project . ` CCS ' can also be used to describe the scrubbing of from ambient air as a climate engineering technique . An integrated pilot-scale CCS power plant was to begin operating in September 2008 in the eastern German power plant Schwarze Pumpe run by utility Vattenfall , to test the technological feasibility and economic efficiency . CCS applied to a modern conventional power plant could reduce emissions to the atmosphere by approximately 80 -- 90 % compared to a plant without CCS . The IPCC estimates that the economic potential of CCS could be between 10 % and 55 % of the total carbon mitigation effort until year 2100 . Carbon dioxide can be captured out of air or fossil fuel power plant flue gas using adsorption ( or carbon scrubbing ) , membrane gas separation , or adsorption technologies . Amines are the leading carbon scrubbing technology . Capturing and compressing may increase the energy needs of a coal-fired CCS plant by 25 -- 40 % . These and other system costs are estimated to increase the cost per watt energy produced by 21 -- 91 % for fossil fuel power plants . Applying the technology to existing plants would be more expensive , especially if they are far from a sequestration site .

Storage of the is envisaged either in deep geological formations , or in the form of mineral carbonates . Deep ocean storage is not currently considered feasible due to the associated effect of ocean acidification . Geological formations are currently considered the most promising sequestration sites . The National Energy Technology Laboratory ( NETL ) reported that North America has enough storage capacity for more than 900 years worth of carbon dioxide at current production rates .

Scientific consensus on global warming , together with the precautionary principle and the fear of non-linear climate transitions , is leading to increased effort to develop new technologies and sciences and carefully manage others in an attempt to mitigate global warming . Carbon capture and storage ( CCS ) for coal-fired power stations has been put forward as a solution to rising greenhouse gas emissions . However , CCS can not deliver in time to avoid dangerous increases in temperatures , as widespread commercial use of CCS is not expected before 2030 . Following the introduction of government mandatory renewable energy targets , more opportunities have opened up for renewable energy technologies such as wind power , photovoltaics , and solar thermal technologies . The deployment of these technologies provides opportunities for mitigating greenhouse gases . A carbon price was introduced on 1 July 2012 by the government of Julia Gillard with the purpose of reducing Australia 's carbon emissions . It requires large businesses ( defined as those with annual carbon dioxide equivalent emissions over 25,000 tonnes annually ) to pay a price for emissions permits . The tax was scrapped by the Abbott government in July 2014 in what was a widely criticised and highly publicised move .", "qid": "450", "docid": "Mitigation_of_global_warming_in_Australia", "rank": 91, "score": 101410 }, { "content": "Title: Life-cycle greenhouse-gas emissions of energy sources Content: Measurement of life-cycle greenhouse gas emissions involves calculating the global-warming potential of electrical energy sources through life-cycle assessment of each energy source .

It plays a large part in the carbon cycle , since the equilibrium point of the carbonate-silicate cycle dictates the pace of carbon release from the lithosphere . The carbonate-silicate cycle involves several chemical reactions that occur in different environments . In the atmosphere , gaseous carbon dioxide ( CO2 ) dissolves in rainwater , forming natural carbonic acid ( H2CO3 ) . This weak acid weathers silicate rocks on continents , slowly dissolving the rock and releasing aqueous minerals through the chemical reaction CaSiO3 ( s ) ( wollastonite ) + 2CO2 ( g ) + H2O ( l ) → Ca + 2HCO ( aq ) ( bicarbonate ) + SiO2 ( aq ) ( dissolved silica ) . These dissolved minerals are eventually carried by water to the ocean , where they are used by living organisms such as foraminifera , radiolarians , coccolithopores , and diatoms to create shells of CaCO3 ( calcite ) or SiO2 ( opal ) through the reactions Ca2 + ( aq ) + 2HCO3 → CaCO3 ( s ) + CO2 ( g ) + H2O ( l ) ( for calcite precipitation ) and SiO2 ( aq ) → SiO2 ( s ) ( for opal precipitation ) . When these organisms die , many shells are remineralized but some shells fall all the way to the sea floor and are buried . The cycle is completed when the sea floor is subducted and carbonate minerals recombine with silicate minerals under temperatures above 300 ° C to reform calcium silicates and release gaseous CO2 through volcanism ( CaCO3 ( s ) + SiO2 ( s ) → CaSiO3 ( s ) + CO2 ( g ) ) . The carbonate-silicate cycle impacts the global carbon cycle , as carbon dioxide is removed from the Earth 's surface through the burial of weathered minerals in deep ocean sediments and returned to the atmosphere through metamorphism and volcanism . However , this process is far from being a closed loop . In Earth history generally the formation of carbonates significantly outpaces the formation of silicates , effectively removing carbon dioxide from the atmosphere . Because carbon dioxide is a potent greenhouse gas , the carbonate-silicate cycle is suspected to initiate ice ages by creating a negative feedback on the global temperature with a typical time scale of a few million years that is capable of countering water vapor and carbon dioxide short-term positive feedback on global temperature . The carbonate-silicate cycle equilibrium point is shifted on Venus due to surface temperatures above 300 ° C , which favor the formation of calcium silicates over weathering .

At the surface of the oceans towards the poles , seawater becomes cooler and more carbonic acid is formed as CO2 becomes more soluble . This is coupled to the ocean 's thermohaline circulation which transports dense surface water into the ocean 's interior ( see the entry on the solubility pump ) . Although the deep ocean contains much more dissolved inorganic carbon than the surface ocean , the concentration is only 15 % higher in the deep ocean as compared to the surface ocean due to the higher volume of the deep ocean . In upper ocean areas of high biological productivity , organisms convert reduced carbon to tissues , or carbonates to hard body parts such as shells and tests . These are , respectively , oxidized ( soft-tissue pump ) and redissolved ( carbonate pump ) at lower average levels of the ocean than those at which they formed , resulting in a downward flow of carbon ( see entry on the biological pump ) . The flux or absorption of carbon dioxide into the world 's oceans is influenced by the presence of widespread viruses within ocean water , that infect many species of bacteria . The resulting bacterial deaths spawn a sequence of events that lead to greatly enlarged respiration of carbon dioxide , enhancing the role of the oceans as a carbon sink . The balance of dissolved inorganic carbon ( DIC ) : dissolved organic carbon ( DOC ) : particle organic carbon is about 2000:38:1 . The CaCO3 counter pump increases the partial pressure of CO2 in the ocean , thus leading to higher outgasing of carbon dioxide . Higher ocean temperatures lead to stronger layering , thus less mixing and less capacity for thermohaline circulation to bring carbon into lower ocean layers . The weathering of silicate rock ( see carbonate-silicate cycle ) . Carbonic acid reacts with weathered rock to produce bicarbonate ions . The bicarbonate ions produced are carried to the ocean , where they are used to make marine carbonates . Unlike dissolved CO2 in equilibrium or tissues , which decay , weathering does not move the carbon into a reservoir from which it can readily return to the atmosphere . Much remains to be learned about the cycling of carbon in the deep ocean . For example , a recent discovery is that larvacean mucus houses ( commonly known as `` sinkers '' ) are created in such large numbers that they can deliver as much carbon to the deep ocean as has been previously detected by sediment traps . Because of their size and composition , these houses are rarely collected in such traps , so most biogeochemical analyses have erroneously ignored them .

It is particularly effective in reservoirs deeper than 2,500 ft. , where will be in a supercritical state , with API oil gravity greater than 22 -- 25 ° and remaining oil saturation greater than 20 % . It should also be noted that carbon dioxide flooding is not affected by the lithology of the reservoir area , but simply by the reservoir porosity and permeability , so that it is viable in both sandstone and carbonate reservoirs . By injecting CO2 into the reservoir , the viscosity of any hydrocarbon will be reduced and hence will be easier to sweep to the production well . As an oil field matures and production rates decline , there is growing incentive to intervene and attempt to increase oil output utilizing tertiary recovery techniques ( also termed improved or enhanced oil recovery ) . Petroleum engineers assess available options for increasing well productivity , options that include chemical injection , thermal/steam injection , and CO2 injection . Based on data-gathering and computer simulations , the most optimal enhanced oil-recovery technique to maximize well-productivity is determined . To increase the rate of oil production , the pressure within the reservoir must be increased . In CO2 flooding , the first step is injection of water into the reservoir , which will cause the reservoir pressure to increase . Once the reservoir has sufficient pressure , the next step is to pump the CO2 down through the same injection wells . The CO2 gas is forced into the reservoir to come into contact with the oil . This creates a miscible zone that can be moved more easily to the production well . Normally the CO2 injection is alternated with water injection and the water acts to sweep the oil towards the production zone . CO2 flooding is the second most common tertiary recovery technique and is used in facilities around the world .

An everyday example is given by one 's experience with carbonated soft drinks , which contain dissolved carbon dioxide . Before opening , the gas above the drink in its container is almost pure carbon dioxide , at a pressure higher than atmospheric pressure . After the bottle is opened , this gas escapes , moving the partial pressure of carbon dioxide above the liquid to be much lower , resulting in degassing as the dissolved carbon dioxide comes out of solution .", "qid": "451", "docid": "Henry's_law", "rank": 45, "score": 82704 }, { "content": "Title: Bosch reaction Content: The Bosch reaction is a chemical reaction between carbon dioxide and hydrogen that produces elemental carbon ( graphite ) , water , and a 10 % return of invested heat .

The overall reaction is as follows : CO2 ( g ) + 2 H2 ( g ) → C ( s ) + 2 H2O ( g ) The above reaction is actually the result of two reactions . The first reaction , the reverse water gas shift reaction , is a fast one : CO2 + H2 → CO + H2O The second reaction controls the reaction rate : CO + H2 → C + H2O The overall reaction produces 2.3 × 103 joules for every gram of carbon dioxide reacted at 650 ° C. Reaction temperatures are in the range of 450 to 600 ° C. The reaction can be accelerated in the presence of an iron , cobalt or nickel catalyst . Ruthenium also serves to speed up the reaction . Together with the Sabatier reaction , the Bosch reaction is studied as a way to remove carbon dioxide and to generate clean water aboard a space station . The reaction is also used to produce graphite for radiocarbon dating with Accelerator Mass Spectrometry . The Bosch reaction is being investigated for use in maintaining space station life support . Though the Bosch reaction would present a completely closed hydrogen and oxygen cycle which only produces atomic carbon as waste , difficulties in maintaining its higher required temperature and properly handling carbon deposits mean that significantly more research will be required before a Bosch reactor can become a reality .

Carboxysomes are thought to have evolved as a consequence of the increase in oxygen concentration in the ancient atmosphere ; this is because oxygen is a competing substrate to carbon dioxide in the RuBisCO reaction . To overcome the inefficiency of RuBisCO , carboxysomes concentrate carbon dioxide inside the shell by means of co-localized carbonic anhydrase activity , which produces carbon dioxide from the bicarbonate that diffuses into the carboxysome . The resulting production of carbon dioxide near RuBisCO decreases the proportion of ribulose-1 ,5 - bisphosphate oxygenation and thereby avoids costly photorespiratory reactions . The surrounding shell provides a barrier to carbon dioxide loss , helping to increase its concentration around RuBisCO .

Seawater is slightly basic ( meaning pH > 7 ) , and the process in question is a shift towards pH-neutral conditions rather than a transition to acidic conditions ( pH < 7 ) . Ocean alkalinity is not changed by the process , or may increase over long time periods due to carbonate dissolution . An estimated 30 -- 40 % of the carbon dioxide from human activity released into the atmosphere dissolves into oceans , rivers and lakes . To achieve chemical equilibrium , some of it reacts with the water to form carbonic acid . Some of these extra carbonic acid molecules react with a water molecule to give a bicarbonate ion and a hydronium ion , thus increasing ocean acidity ( H + ion concentration ) . Between 1751 and 1996 surface ocean pH is estimated to have decreased from approximately 8.25 to 8.14 , representing an increase of almost 35 % in H + ion concentration in the world 's oceans . Earth System Models project that within the last decade ocean acidity exceeded historical analogues and in combination with other ocean biogeochemical changes could undermine the functioning of marine ecosystems and disrupt the provision of many goods and services associated with the ocean . Increasing acidity is thought to have a range of potentially harmful consequences for marine organisms , such as depressing metabolic rates and immune responses in some organisms , and causing coral bleaching . By increasing the presence of free hydrogen ions , each molecule of carbonic acid that forms in the oceans ultimately results in the conversion of two carbonate ions into bicarbonate ions . This net decrease in the amount of carbonate ions available makes it more difficult for marine calcifying organisms , such as coral and some plankton , to form biogenic calcium carbonate , and such structures become vulnerable to dissolution . Ongoing acidification of the oceans threatens food chains connected with the oceans . As members of the InterAcademy Panel , 105 science academies have issued a statement on ocean acidification recommending that by 2050 , global emissions be reduced by at least 50 % compared to the 1990 level . While ongoing ocean acidification is anthropogenic in origin , it has occurred previously in Earth 's history . The most notable example is the Paleocene-Eocene Thermal Maximum ( PETM ) , which occurred approximately 56 million years ago .

Since GHG emissions caused by the combustion of fossil fuels are closely related to the carbon content of the respective fuels , a tax on these emissions can be levied by taxing the carbon content of fossil fuels at any point in the product cycle of the fuel . Carbon tax offers social and economic benefits . It is a tax that increases revenue without significantly altering the economy while simultaneously promoting objectives of climate change policy . The objective of a carbon tax is to reduce the harmful and unfavorable levels of carbon dioxide emissions , thereby decelerating climate change and its negative effects on the environment and human health . Carbon taxes offer a potentially cost-effective means of reducing greenhouse gas emissions . From an economic perspective , carbon taxes are a type of Pigovian tax . They help to address the problem of emitters of greenhouse gases not facing the full social cost of their actions . Carbon taxes can be a regressive tax , in that they may directly or indirectly affect low-income groups disproportionately . The regressive impact of carbon taxes could be addressed by using tax revenues to favour low-income groups . A number of countries have implemented carbon taxes or energy taxes that are related to carbon content . Most environmentally related taxes with implications for greenhouse gas emissions in OECD countries are levied on energy products and motor vehicles , rather than on emissions directly . Opposition to increased environmental regulation such as carbon taxes often centers on concerns that firms might relocate and/or people might lose their jobs .

[ { "content": "Title: History of climate change science Content: The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect first identified . In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world . The latter effect is currently causing global warming , and `` climate change '' is often used to describe human-specific impacts .", "qid": "452", "docid": "History_of_climate_change_science", "rank": 1, "score": 106031 }, { "content": "Title: Nature Climate Change Content: Nature Climate Change is a monthly peer-reviewed scientific journal published by Nature Publishing Group covering all aspects of research on global warming , especially its effects .

The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect . This scientific opinion is expressed in synthesis reports , by scientific bodies of national or international standing , and by surveys of opinion among climate scientists . Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys . National and international science academies and scientific societies have assessed current scientific opinion on global warming . These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change . The IPCC Fourth Assessment Report stated that : Warming of the climate system is unequivocal , as evidenced by increases in global average air and ocean temperatures , the widespread melting of snow and ice , and rising global average sea level . Most of the global warming since the mid-20th century is very likely due to human activities . Benefits and costs of climate change for -LSB- human -RSB- society will vary widely by location and scale . Some of the effects in temperate and polar regions will be positive and others elsewhere will be negative . Overall , net effects are more likely to be strongly negative with larger or more rapid warming . The range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time . The resilience of many ecosystems is likely to be exceeded this century by an unprecedented combination of climate change , associated disturbances ( e.g. flooding , drought , wildfire , insects , ocean acidification ) and other global change drivers ( e.g. land-use change , pollution , fragmentation of natural systems , over-exploitation of resources ) . Some scientific bodies have recommended specific policies to governments , and science can play a role in informing an effective response to climate change . Policy decisions , however , may require value judgements and so are not included in the scientific opinion . No scientific body of national or international standing maintains a formal opinion dissenting from any of these main points . The last national or international scientific body to drop dissent was the American Association of Petroleum Geologists , which in 2007 updated its statement to its current non-committal position .

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction . Climate changes is projected to affect individual organisms , populations , species distributions and ecosystem composition and function both directly ( ex . Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years .

It involves denial , dismissal , unwarranted doubt or contrarian views which strongly depart from the scientific opinion on climate change , including the extent to which it is caused by humans , its impacts on nature and human society , or the potential of adaptation to global warming by human actions . Some deniers do endorse the term , but others often prefer the term climate change skepticism , although this is a misnomer for those who deny anthropogenic global warming . In effect , the two terms form a continuous , overlapping range of views , and generally have the same characteristics : both reject , to a greater or lesser extent , mainstream scientific opinion on climate change . Climate change denial can also be implicit , when individuals or social groups accept the science but fail to come to terms with it or to translate their acceptance into action . Several social science studies have analyzed these positions as forms of denialism . Campaigning to undermine public trust in climate science has been described as a `` denial machine '' of industrial , political and ideological interests , supported by conservative media and skeptical bloggers in manufacturing uncertainty about global warming . In the public debate , phrases such as climate skepticism have frequently been used with the same meaning as climate denialism . The labels are contested : those actively challenging climate science commonly describe themselves as `` skeptics '' , but many do not comply with common standards of scientific skepticism and , regardless of evidence , persistently deny the validity of human caused global warming . Although scientific opinion on climate change is that human activity is extremely likely to be the primary driver of climate change , the politics of global warming have been affected by climate change denial , hindering efforts to prevent climate change and adapt to the warming climate . Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none . Of the world 's countries , the climate change denial industry is most powerful in the United States . Since January 2015 , the United States Senate Committee on Environment and Public Works has been chaired by oil lobbyist and climate change denier Jim Inhofe . Inhofe is notorious for having called climate change `` the greatest hoax ever perpetrated against the American people '' and for having claimed to have debunked the alleged hoax in February 2015 when he brought a snowball with him in the Senate chamber and tossed it across the floor . Organised campaigning to undermine public trust in climate science is associated with conservative economic policies and backed by industrial interests opposed to the regulation of emissions . Climate change denial has been associated with the fossil fuels lobby , the Koch brothers , industry advocates and libertarian think tanks , often in the United States . More than 90 % of papers sceptical on climate change originate from right-wing think tanks . The total annual income of these climate change counter-movement-organizations is roughly $ 900 million . Between 2002 and 2010 , nearly $ 120 million ( # 77 million ) was anonymously donated via the Donors Trust and Donors Capital Fund to more than 100 organisations seeking to undermine the public perception of the science on climate change . In 2013 the Center for Media and Democracy reported that the State Policy Network ( SPN ) , an umbrella group of 64 U.S. think tanks , had been lobbying on behalf of major corporations and conservative donors to oppose climate change regulation . Since the late 1970s , oil companies have published research broadly in line with the standard views on global warming . Despite this , oil companies organized a climate change denial campaign to disseminate public disinformation for several decades , a strategy that has been compared to the organized denial of the hazards of tobacco smoking by tobacco companies .", "qid": "452", "docid": "Climate_change_denial", "rank": 29, "score": 84592 }, { "content": "Title: Effects of global warming Content: The effects of global warming are the environmental and social changes caused ( directly or indirectly ) by human emissions of greenhouse gases .

The term is most often applied to the Earth or some parts of Earth . This environment encompasses the interaction of all living species , climate , weather , and natural resources that affect human survival and economic activity . The concept of the natural environment can be distinguished by components : Complete ecological units that function as natural systems without massive civilized human intervention , including all vegetation , microorganisms , soil , rocks , atmosphere , and natural phenomena that occur within their boundaries and their nature Universal natural resources and physical phenomena that lack clear-cut boundaries , such as air , water , and climate , as well as energy , radiation , electric charge , and magnetism , not originating from civilized human activity In contrast to the natural environment is the built environment . In such areas where man has fundamentally transformed landscapes such as urban settings and agricultural land conversion , the natural environment is greatly modified into a simplified human environment . Even acts which seem less extreme , such as building a mud hut or a photovoltaic system in the desert , modify the natural environment into an artificial one . Though many animals build things to provide a better environment for themselves , they are not human , hence beaver dams and the works of Mound-building termites are thought of as natural . People seldom find absolutely natural environments on Earth , and naturalness usually varies in a continuum , from 100 % natural in one extreme to 0 % natural in the other . More precisely , we can consider the different aspects or components of an environment , and see that their degree of naturalness is not uniform . If , for instance , in an agricultural field , the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil , but the structure is quite different .

Even if emissions are stabilized relatively soon , global warming and its effects will last many years , and adaptation will be necessary to the resulting changes in climate . Adaptation is especially important in developing countries since those countries are predicted to bear the brunt of the effects of global warming . That is , the capacity and potential for humans to adapt ( called adaptive capacity ) is unevenly distributed across different regions and populations , and developing countries generally have less capacity to adapt ( Schneider et al. , 2007 ) . Furthermore , the degree of adaptation correlates to the situational focus on environmental issues . Therefore , adaptation requires the situational assessment of sensitivity and vulnerability to environmental impacts . Adaptive capacity is closely linked to social and economic development ( IPCC , 2007 ) . The economic costs of adaptation to climate change are likely to cost billions of dollars annually for the next several decades , though the amount of money needed is unknown . Donor countries promised an annual $ 100 billion by 2020 through the Green Climate Fund for developing countries to adapt to climate change . However , while the fund was set up during COP16 in Cancún , concrete pledges by developed countries have not been forthcoming . The adaptation challenge grows with the magnitude and the rate of climate change . Another response to climate change , known as climate change mitigation ( Verbruggen , 2007 ) is to reduce greenhouse gas ( GHG ) emissions and/or enhance the removal of these gases from the atmosphere ( through carbon sinks ) . Even the most effective reductions in emissions , however , would not prevent further climate change impacts , making the need for adaptation unavoidable ( Klein et al. , 2007 ) . In a literature assessment , Klein et al. ( 2007 ) assessed options for adaptation . They concluded , with very high confidence , that in the absence of mitigation efforts , the effects of climate change would reach such a magnitude as to make adaptation impossible for some natural ecosystems . Others are concerned that climate adaptation programs might interfere with the existing development programs and thus lead to unintended consequences for vulnerable groups .

Climate is the average weather, typically over a period of 30 years, and is determined by a combination of processes in the climate system, such as ocean currents and wind patterns. Circulation in the atmosphere and oceans is primarily driven by solar radiation and transports heat from the tropical regions to regions that receive less energy from the Sun. The water cycle also moves energy throughout the climate system. In addition, different chemical elements, necessary for life, are constantly recycled between the different components. The climate system can change due to internal variability and external forcings. These external forcings can be natural, such as variations in solar intensity and volcanic eruptions, or caused by humans. Accumulation of heat-trapping greenhouse gases, mainly being emitted by people burning fossil fuels, is causing global warming.

Climate change mitigation generally involves reductions in human ( anthropogenic ) emissions of greenhouse gases ( GHGs ) . Mitigation may also be achieved by increasing the capacity of carbon sinks , e.g. , through reforestation . Mitigation policies can substantially reduce the risks associated with human-induced global warming . According to the IPCC 's 2014 assessment report , `` Mitigation is a public good ; climate change is a case of the ` tragedy of the commons . Effective climate change mitigation will not be achieved if each agent ( individual , institution or country ) acts independently in its own selfish interest ( see international cooperation and emissions trading ) , suggesting the need for collective action . Some adaptation actions , on the other hand , have characteristics of a private good as benefits of actions may accrue more directly to the individuals , regions , or countries that undertake them , at least in the short term . Nevertheless , financing such adaptive activities remains an issue , particularly for poor individuals and countries . '' Examples of mitigation include phasing out fossil fuels by switching to low-carbon energy sources , such as renewable and nuclear energy , and expanding forests and other `` sinks '' to remove greater amounts of carbon dioxide from the atmosphere . Energy efficiency may also play a role , for example , through improving the insulation of buildings . Another approach to climate change mitigation is climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) . The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of GHGs at a level that would prevent dangerous human interference of the climate system . Scientific analysis can provide information on the impacts of climate change , but deciding which impacts are dangerous requires value judgments . In 2010 , Parties to the UNFCCC agreed that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . With the Paris Agreement of 2015 this was confirmed , but was revised with a new target laying down `` parties will do the best '' to achieve warming below 1.5 ° C . The current trajectory of global greenhouse gas emissions does not appear to be consistent with limiting global warming to below 1.5 or 2 ° C .

There are some parallels between atmospheric chemistry and anthropogenic emissions in the discussions which have taken place and the regulatory attempts which have been made . Most important is that the gases causing both problems have long lifetimes after emission to the atmosphere , thus causing problems which are difficult to reverse . However , the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol that amended it are seen as success stories , while the Kyoto Protocol on anthropogenic climate change has largely failed . Currently efforts are being undertaken to assess the reasons and to use synergies , for example with regard to data reporting and policy design and further exchanging of information .

It then entered into force on 21 March 1994 , after a sufficient number of countries had ratified it . The UNFCCC objective is to `` stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system '' . The framework sets no binding limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms . Instead , the framework outlines how specific international treaties ( called `` protocols '' or `` Agreements '' ) may be negotiated to specify further action towards the objective of the UNFCCC . Initially an Intergovernmental Negotiating Committee ( INC ) produced the text of the Framework Convention during its meeting in New York from 30 April to 9 May 1992 . The UNFCCC was adopted on 9 May 1992 , and opened for signature on 4 June 1992 . The UNFCCC has 197 parties as of December 2015 . The convention enjoys broad legitimacy , largely due to its nearly universal membership . The parties to the convention have met annually from 1995 in Conferences of the Parties ( COP ) to assess progress in dealing with climate change . In 1997 , the Kyoto Protocol was concluded and established legally binding obligations for developed countries to reduce their greenhouse gas emissions in the period 2008-2012 . The 2010 Cancún agreements state that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . The Protocol was amended in 2012 to encompass the period 2013-2020 in the Doha Amendment , which - as of December 2015 - had not entered into force . In 2015 the Paris Agreement was adopted , governing emission reductions from 2020 on through commitments of countries in ambitious Nationally Determined Contributions . The Paris Agreement entered into force on November 4th , 2016 . One of the first tasks set by the UNFCCC was for signatory nations to establish national greenhouse gas inventories of greenhouse gas ( GHG ) emissions and removals , which were used to create the 1990 benchmark levels for accession of Annex I countries to the Kyoto Protocol and for the commitment of those countries to GHG reductions . Updated inventories must be submitted annually by Annex I countries . The UNFCCC is also the name of the United Nations Secretariat charged with supporting the operation of the Convention , with offices in Haus Carstanjen , and the UN Campus ( known as Langer Eugen ) Bonn , Germany . From 2010 to 2016 the head of the secretariat was Christiana Figueres . In July 2016 , Patricia Espinosa from Mexico succeeded Figueres .

If a planet 's atmosphere contains radiatively active gases ( i.e. , greenhouse gases ) the atmosphere will radiate energy in all directions . Part of this radiation is directed towards the surface , warming it . The downward component of this radiation -- that is , the strength of the greenhouse effect -- will depend on the atmosphere 's temperature and on the amount of greenhouse gases that the atmosphere contains . On Earth , the atmosphere is warmed by absorption of infrared thermal radiation from the underlying surface ( heated by the sun ) , absorption of shorter wavelength radiant energy from the sun , and convective heat fluxes from the surface . Greenhouse gases in the atmosphere radiate energy , some of which is directed to the surface and lower atmosphere .

Greenhouse gas inventories , typically use Global warming potential ( GWP ) values to combine emissions of various greenhouse gases into a single weighted value of emissions . Some of the key examples of greenhouse gas inventories include : All Annex I countries are required to report annual emissions and sinks of greenhouse gases under the United Nations Framework Convention on Climate Change ( UNFCCC ) National governments that are Parties to the UNFCCC and/or the Kyoto Protocol are required to submit annual inventories of all anthropogenic greenhouse gas emissions from sources and removals from sinks . The Kyoto Protocol includes additional requirements for national inventory systems , inventory reporting , and annual inventory review for determining compliance with Articles 5 and 8 of the Protocol . Project developers under the Clean Development Mechanism of the Kyoto Protocol prepare inventories as part of their project baselines . Corporation and other entities can prepare greenhouse gas inventories to track progress towards meeting an emission reduction goal .

This test explosion was the first test of a boosted fission weapon . In this test deuterium-tritium ( D-T ) gas was injected into the enriched uranium core of a nuclear fission bomb . The extreme heat of the fissioning bomb produced thermonuclear fusion reactions within the D-T gas , but not enough of them to be considered a full nuclear fusion bomb . This fusion reaction released a large number of free neutrons , which greatly increased the efficiency of the nuclear fission reaction . The explosive yield of this bomb was 45.5 kilotons , about twice the yield of the unboosted bomb . This bomb was known as the `` Booster '' in its development stages , a name for the mechanism coined by Edward Teller in September 1947 . Planning for it had begun in the late 1940s . According to the researcher Chuck Hansen , it was mentioned in official U.S. Atomic Energy Commission documents as early as 1947 . The main problems in development were making modifications to the fission core in order to accept the gas correctly without reducing its own efficiency . The 1951 test was primarily to test the nuclear principles involved , and to gain research data , and it was not considered a design for a weaponizable device . Even as late as 1954 , no boosted weapon had entered into the nuclear-weapons stockpile , and the only use for the Greenhouse Item nuclear test had been for its research results . The `` Booster '' device was detonated at 6:17 am on May 25 , 1951 from a 200 ft on the island of Engebi in the Enewetok Atoll , and its fusion fuel was injected by means of a cryogenic pump at the base of the tower .", "qid": "454", "docid": "Greenhouse_Item", "rank": 13, "score": 78564 }, { "content": "Title: Greenhouse gas monitoring Content: Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels .

Thus heat is easily let in , but is partially trapped by these gases as it tries to leave .

In the long-term , thermal equilibrium is reached when all the heat energy arriving on the planet is leaving again at the same rate . In this idealized model , the greenhouse gases cause the surface of the planet to be warmer than it would be without them , in order for the required amount of heat energy finally to be radiated out into space from the top of the atmosphere .

This means the importing country takes responsibility for emissions related to production of the exporting country 's exports . By these definitions production-based emissions include exports but exclude imports and emissions embodied in international trade , whereas consumption-based emissions refer to the reverse ( Table 1 ) . Which technique is applied by policymakers is fundamental as each can generate a very different NEI .

Venting of natural gas , flaring , accidental releases and storage losses accounted for an additional 38 per cent . Fugitive emissions present other risks and hazards . Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities . In situations where large amounts of flammable liquids and gases are contained under pressure , leaks also increase the risk of fire and explosion . Leaks from pressurized process equipment generally occur through valves , pipe connections , mechanical seals , or related equipment . Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks . Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks , fugitive emissions can be a significant proportion of total emissions . Though the quantities of leaked gases may be small , gases that have serious health or environmental impacts can cause a significant problem . To minimize and control leaks at process facilities operators carry out regular leak detection and repair activities . Routine inspections of process equipment with gas detectors can be used to identify leaks and estimate the leak rate in order to decide on appropriate corrective action . Proper routine maintenance of equipment reduces the likelihood of leaks . Because of the technical difficulties and costs of detecting and quantifying actual fugitive emissions at a site or facility , and the variability and intermittent nature of emission flow rates , bottom-up estimates based on standard emission factors are generally used for annual reporting purposes . New technologies are under development that could revolutionize the detection and monitoring of fugitive emissions . One technology , known as differential absorption lidar ( DIAL ) , can be used to remotely measure concentration profiles of hydrocarbons in the atmosphere up to several hundred meters from a facility . DIAL has been used for refinery surveys in Europe for over 15 years . A pilot study carried out in 2005 using DIAL found that actual emissions at a refinery were fifteen times higher than those previously reported using the emission factor approach . The fugitive emissions were equivalent to 0.17 % of the refinery throughput . Portable gas leak imaging cameras are also a new technology that can be used to improve leak detection and repair , leading to reduced fugitive emissions . The cameras use infrared imaging technology to produce video images in which invisible gases escaping from leak sources can be clearly identified .", "qid": "454", "docid": "Fugitive_emissions", "rank": 39, "score": 70188 }, { "content": "Title: Arctic methane emissions Content: Arctic methane release is the release of methane from seas and soils in permafrost regions of the Arctic .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation .

By subsector , road transport is the largest contributor to global warming . Environmental regulations in developed countries have reduced the individual vehicle 's emission ; however , this has been offset by an increase in the number of vehicles , and more use of each vehicle . Some pathways to reduce the carbon emissions of road vehicles considerably have been studied . Energy use and emissions vary largely between modes , causing environmentalists to call for a transition from air and road to rail and human-powered transport , and increase transport electrification and energy efficiency . The transportation sector is a major source of greenhouse gas emissions ( GHGs ) in the United States . An estimated 30 percent of national GHGs are directly attributable to transportation -- and in some regions , the proportion is even higher . Transportation methods are the greatest contributing source of GHGs in the U.S. , accounting for 47 percent of the net increase in total U.S. emissions since 1990 . Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl , which can consume natural habitat and agricultural lands . By reducing transportation emissions globally , it is predicted that there will be significant positive effects on Earth 's air quality , acid rain , smog and climate change . The health impact of transport emissions is also of concern . A recent survey of the studies on the effect of traffic emissions on pregnancy outcomes has linked exposure to emissions to adverse effects on gestational duration and possibly also intrauterine growth .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world .

More precisely , GDRs seeks to transparently calculate national `` fair shares '' in the costs of an emergency global climate mobilization , in a manner that takes explicit account of the fact that , as things now stand , global political and economic life is divided along both North/South and rich/poor lines . Critically , GDRs approaches climate protection and economic development as two sides of one coin . Its goal is developmental justice , as it might exist even in a world that 's compelled to rapidly reduce greenhouse-gas emissions to near-zero levels . The GDRs analysis suggests that rapid climate stabilization will prove impossible without an extremely strong commitment -- a right -- to a dignified level of sustainable human development ( humanity ) . A right to life free from the privations of poverty . The GDRs approach builds , whenever possible , upon established scientific and political understandings . In particular , it explicitly codifies the foundational call of the United Nations Framework Convention on Climate Change , which seeks `` the widest possible cooperation by all countries and their participation in an effective and appropriate international response , in accordance with their common but differentiated responsibilities and respective capabilities . '' The GDRs strategy is to transparently calculate responsibility and capacity for all countries , with respect to explicit assumptions and benchmarks that can be clearly debated , negotiated , and , when necessary , changed . By so doing , it seeks to provide a coherent , transparent , and compelling way of calculating and comparing national `` fair shares '' -- broadly defined -- of the cost of the global climate transition . The goal of the GDRs effort is a sustainable mobilization that can be accepted as fair around the world . National obligations are calculated as shares of a global obligation that includes adaptation as well as mitigation . The approach here does not traditionally exhibit political realism , for that term is generally understood to imply an approach that starts with what is politically realistic today . The GDRs approach , in contrast , seeks to outline an approach that is consistent with the requirements of the climate science . In the GDRs framework , a country 's obligation to act is based upon its climate debt -- its responsibility for contributing to climate change -- and equally upon its capacity to act . Responsibility and capacity are both defined with respect to a `` development threshold '' that exempts the responsibilities and resources of the poor -- survival resources and survival income -- from being considered when calculating national obligation . Thus , GDRs can be seen as a reference framework intended to support clear , useful thinking about `` comparability of effort , '' even between widely disparate developed and developing nations . Finally , GDRs is not an academic exercise . Climate stabilization is a global commons problem , one that is fundamentally defined by the problem of fair use . GDRs , by transparently calculating principle-based obligations to protect the global climate system , sets out a framework by which fair-shares emissions rights can be defined , calculated , understood , debated , and negotiated .

Carbon offsets are measured in metric tons of carbon dioxide-equivalent ( CO2e ) and may represent six primary categories of greenhouse gases : carbon dioxide , methane ( CH4 ) , nitrous oxide ( N2O ) , perfluorocarbons ( PFCs ) , hydrofluorocarbons ( HFCs ) , and sulfur hexafluoride ( SF6 ) . One carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases . There are two markets for carbon offsets . In the larger , compliance market , companies , governments , or other entities buy carbon offsets in order to comply with caps on the total amount of carbon dioxide they are allowed to emit . This market exists in order to achieve compliance with obligations of Annex 1 Parties under the Kyoto Protocol , and of liable entities under the EU Emission Trading Scheme . In 2006 , about $ 5.5 billion of carbon offsets were purchased in the compliance market , representing about 1.6 billion metric tons of CO2e reductions . In the much smaller , voluntary market , individuals , companies , or governments purchase carbon offsets to mitigate their own greenhouse gas emissions from transportation , electricity use , and other sources . For example , an individual might purchase carbon offsets to compensate for the greenhouse gas emissions caused by personal air travel . Many companies ( see list ) offer carbon offsets as an up-sell during the sales process so that customers can mitigate the emissions related with their product or service purchase ( such as offsetting emissions related to a vacation flight , car rental , hotel stay , consumer good , etc. ) . In 2008 , about $ 705 million of carbon offsets were purchased in the voluntary market , representing about 123.4 million metric tons of CO2e reductions . Some fuel suppliers in the UK offer fuel which has been carbon offset such as Fuel dyes . Offsets are typically achieved through financial support of projects that reduce the emission of greenhouse gases in the short - or long-term . The most common project type is renewable energy , such as wind farms , biomass energy , or hydroelectric dams . Others include energy efficiency projects , the destruction of industrial pollutants or agricultural byproducts , destruction of landfill methane , and forestry projects . Some of the most popular carbon offset projects from a corporate perspective are energy efficiency and wind turbine projects . Carbon offsetting has gained some appeal and momentum mainly among consumers in western countries who have become aware and concerned about the potentially negative environmental effects of energy-intensive lifestyles and economies . The Kyoto Protocol has sanctioned offsets as a way for governments and private companies to earn carbon credits that can be traded on a marketplace . The protocol established the Clean Development Mechanism ( CDM ) , which validates and measures projects to ensure they produce authentic benefits and are genuinely `` additional '' activities that would not otherwise have been undertaken . Organizations that are unable to meet their emissions quota can offset their emissions by buying CDM-approved Certified Emissions Reductions . Emissions from burning fuel , such as red diesel , has pushed one UK fuel supplier to create a carbon offset fuel named Carbon Offset Red Diesel . Offsets may be cheaper or more convenient alternatives to reducing one 's own fossil-fuel consumption . However , some critics object to carbon offsets , and question the benefits of certain types of offsets . Due diligence is recommended to help businesses in the assessment and identification of `` good quality '' offsets to ensure offsetting provides the desired additional environmental benefits , and to avoid reputational risk associated with poor quality offsets . Offsets are viewed as an important policy tool to maintain stable economies and to improve sustainability . One of the hidden dangers of climate change policy is unequal prices of carbon in the economy , which can cause economic collateral damage if production flows to regions or industries that have a lower price of carbon -- unless carbon can be purchased from that area , which offsets effectively permit , equalizing the price .", "qid": "454", "docid": "Carbon_offset", "rank": 82, "score": 64884 }, { "content": "Title: Gas leak Content: In common usage , a gas leak refers to a leak of natural gas or other gaseous product from a pipeline or other containment into a living area or any other area where the gas should not be present .

This hypothesis had little support in the scientific community , but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the full scope of the scientific climate literature , which showed a larger and faster-growing body of literature projecting future warming due to greenhouse gas emissions . The current scientific opinion on climate change is that the Earth has not durably cooled , but underwent global warming throughout the 20th century .", "qid": "455", "docid": "Global_cooling", "rank": 1, "score": 132864 }, { "content": "Title: Scientific opinion on climate change Content: The scientific opinion on climate change is the overall judgment among scientists regarding the extent to which global warming is occurring , its causes , and its probable consequences . The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect . This scientific opinion is expressed in synthesis reports , by scientific bodies of national or international standing , and by surveys of opinion among climate scientists . Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys . National and international science academies and scientific societies have assessed current scientific opinion on global warming . These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change . The IPCC Fourth Assessment Report stated that : Warming of the climate system is unequivocal , as evidenced by increases in global average air and ocean temperatures , the widespread melting of snow and ice , and rising global average sea level . Most of the global warming since the mid-20th century is very likely due to human activities . Benefits and costs of climate change for -LSB- human -RSB- society will vary widely by location and scale . Some of the effects in temperate and polar regions will be positive and others elsewhere will be negative . Overall , net effects are more likely to be strongly negative with larger or more rapid warming . The range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time . The resilience of many ecosystems is likely to be exceeded this century by an unprecedented combination of climate change , associated disturbances ( e.g. flooding , drought , wildfire , insects , ocean acidification ) and other global change drivers ( e.g. land-use change , pollution , fragmentation of natural systems , over-exploitation of resources ) . Some scientific bodies have recommended specific policies to governments , and science can play a role in informing an effective response to climate change . Policy decisions , however , may require value judgements and so are not included in the scientific opinion . No scientific body of national or international standing maintains a formal opinion dissenting from any of these main points . The last national or international scientific body to drop dissent was the American Association of Petroleum Geologists , which in 2007 updated its statement to its current non-committal position .

Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change .

The neoglaciation has no well-marked universal beginning : local conditions and ecological inertia affected the onset of detectably cooler ( and wetter ) conditions . Driven inexorably by the Milankovitch cycle , cooler summers in higher latitudes of North America , which would cease to completely melt the annual snowfall , were masked at first by the presence of the slowly disappearing continental ice sheets , which persisted long after the astronomically calculated moment of maximum summer warmth : `` the neoglaciation can be said to have begun when the cooling caught up with the warming '' , remarked E. C. Pielou .

Whether it has been temporarily or semi-permanently stalled , neoglaciation has been marked by a retreat from the warm conditions of the Climatic Optimum and the advance or reformation of glaciers that had not existed since the last ice age .

These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century , with the instrumental temperature record by 2000 exceeding earlier temperatures . The term `` hockey stick graph '' was coined by the climatologist Jerry Mahlman , to describe the pattern shown by the ( MBH99 ) reconstruction , envisaging a graph that is relatively flat with a downward trend to 1900 as forming an ice hockey stick 's `` shaft '' followed by a sharp , steady increase corresponding to the `` blade '' portion . The reconstructions have featured in Intergovernmental Panel on Climate Change ( IPCC ) reports as evidence of global warming . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . Paleoclimatology dates back to the 19th century , and the concept of examining varves in lake beds and tree rings to track local climatic changes was suggested in the 1930s . In the 1960s , Hubert Lamb generalised from historical documents and temperature records of central England to propose a Medieval Warm Period from around 900 to 1300 , followed by Little Ice Age . This was the basis of a `` schematic diagram '' featured in the IPCC First Assessment Report of 1990 beside cautions that the medieval warming might not have been global . The use of indicators to get quantitative estimates of the temperature record of past centuries was developed , and by the late 1990s a number of competing teams of climatologists found indications that recent warming was exceptional . introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large scale reconstructions . Their study was featured in the IPCC Second Assessment Report of 1995 . In 1998 Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 with shading emphasising that uncertainties ( to two standard error limits ) were much greater in earlier centuries . independently produced a CPS reconstruction extending back for a thousand years , and ( MBH99 ) used the MBH98 methodology to extend their study back to 1000 . A version of the MBH99 graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , which also drew on Jones et al. 1998 and three other reconstructions to support the conclusion that , in the Northern Hemisphere , the 1990s was likely to have been the warmest decade and 1998 the warmest year during the past 1,000 years . The graph became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th century warmth was exceptional . In 2003 , as lobbying over the 1997 Kyoto Protocol intensified , a paper claiming greater medieval warmth was quickly dismissed by scientists in the Soon and Baliunas controversy . Later in 2003 , Stephen McIntyre and Ross McKitrick published disputing the data used in MBH98 paper . In 2004 Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 McIntyre and McKitrick published criticisms of the principal components analysis methodology as used in MBH98 and MBH99 . Their analysis was subsequently disputed by published papers including and which pointed to errors in the McIntyre and McKitrick methodology . Political disputes led to the formation of a panel of scientists convened by the National Research Council , their North Report in 2006 supported Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result . More than two dozen reconstructions , using various statistical methods and combinations of proxy records , support the broad consensus shown in the original 1998 hockey-stick graph , with variations in how flat the pre-20th century `` shaft '' appears . The 2007 IPCC Fourth Assessment Report cited 14 reconstructions , 10 of which covered 1,000 years or longer , to support its strengthened conclusion that it was likely that Northern Hemisphere temperatures during the 20th century were the highest in at least the past 1,300 years .

Climate is the average weather, typically over a period of 30 years, and is determined by a combination of processes in the climate system, such as ocean currents and wind patterns. Circulation in the atmosphere and oceans is primarily driven by solar radiation and transports heat from the tropical regions to regions that receive less energy from the Sun. The water cycle also moves energy throughout the climate system. In addition, different chemical elements, necessary for life, are constantly recycled between the different components. The climate system can change due to internal variability and external forcings. These external forcings can be natural, such as variations in solar intensity and volcanic eruptions, or caused by humans. Accumulation of heat-trapping greenhouse gases, mainly being emitted by people burning fossil fuels, is causing global warming. Human activity also releases cooling aerosols, but their net effect is far less than that of greenhouse gases.

The project was funded by the National Science Foundation as part of the International Decade of Ocean Exploration ( 1970s ) and is based in large part of the collection and analysis of a very large number of sediment cores to create a snapshot of conditions across the oceans . The CLIMAP project also resulted in maps of vegetative zones across the continents and the estimated extent of glaciation at the time . Most CLIMAP results aim to describe the Earth as it was 18 thousand years ago , but there was also an analysis to look at conditions during the previous interglacial -- 120 thousand years ago ( CLIMAP 1981 ) . CLIMAP has been a cornerstone of paleoclimate research and remains the most used sea surface temperature reconstruction of the global ocean during the last glacial maximum ( Yin and Battisti 2001 ) , but it has also been persistently controversial . CLIMAP resulted in estimates of global cooling of only 3.0 ± 0.6 ° C relative to the modern day ( Hoffert and Covey 1992 ) . The climate change during an ice age that occurs far from the continental ice sheets themselves is believed to be primarily controlled by changes in greenhouse gases , hence the conditions during the last glacial maximum provide a natural experiment for measuring the impact of changes in greenhouse gases on climate . The cited estimates of 3.0 ° C implies a climate sensitivity to carbon dioxide changes at the low end of the range proposed by the Intergovernmental Panel on Climate Change . However , CLIMAP also suggested that some of the tropics and in particular much of the Pacific Ocean were warmer than they are today . To date , no climate model has been able to reproduce the proposed warming in the Pacific ( Yin and Battisti 2001 ) , with most preferring a several degree cooling . Also , it appears that climate models which are forced to match the CLIMAP sea surface measurements are too warm to match estimates for changes at continental locations ( Pinot et al. 1999 ) . This suggests that either climate model design is missing some important unknown factor , or CLIMAP systematically overestimated the temperatures in the tropical oceans during the last glacial , though there is at present no consistent explanation for why or how this should have happened . Unfortunately cost and difficulty of collecting sediment cores from the open Pacific has limited the availability of samples that might help to confirm or disprove these observations . If the Pacific reconstruction is assumed to be in error , it would result in a larger climate sensitivity to changes in greenhouse gases .", "qid": "455", "docid": "Climate:_Long_range_Investigation,_Mapping,_and_Prediction", "rank": 50, "score": 85563 }, { "content": "Title: Copenhagen Diagnosis Content: The Copenhagen Diagnosis is a report written by twenty-six climate scientists from eight countries .

It has attracted sustained study from planetologists and climatologists . While Mars 's climate has similarities to Earth 's , including periodic ice ages , there are also important differences , such as much lower thermal inertia . Mars ' atmosphere has a scale height of approximately 11 km , 60 % greater than that on Earth . The climate is of considerable relevance to the question of whether life is or was present on the planet . The climate briefly received more interest in the news due to NASA measurements indicating increased sublimation of the south polar icecap leading to some popular press speculation that Mars was undergoing a parallel bout of global warming , although Mars ' average temperature has actually cooled in recent decades . Mars has been studied by Earth-based instruments since the 17th century but it is only since the exploration of Mars began in the mid-1960s that close-range observation has been possible . Flyby and orbital spacecraft have provided data from above , while direct measurements of atmospheric conditions have been provided by a number of landers and rovers . Advanced Earth orbital instruments today continue to provide some useful `` big picture '' observations of relatively large weather phenomena . The first Martian flyby mission was Mariner 4 which arrived in 1965 . That quick two-day pass ( July 14 -- 15 , 1965 ) was limited and crude in terms of its contribution to the state of knowledge of Martian climate . Later Mariner missions ( Mariner 6 , and Mariner 7 ) filled in some of the gaps in basic climate information . Data-based climate studies started in earnest with the Viking program in 1975 and continues with such probes as the Mars Reconnaissance Orbiter .

In the scientific literature , there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases . No scientific body of national or international standing disagrees with this view , though a few organizations with members in extractive industries hold non-committal positions . Disputes over the key scientific facts of global warming are more prevalent in the media than in the scientific literature , where such issues are treated as resolved , and such disputes are more prevalent in the United States than globally . Political and popular debate concerning the existence and cause of climate change includes the reasons for the increase seen in the instrumental temperature record , whether the warming trend exceeds normal climatic variations , and whether human activities have contributed significantly to it . Scientists have resolved these questions decisively in favour of the view that the current warming trend exists and is ongoing , that human activity is the cause , and that it is without precedent in at least 2000 years . Public disputes that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases ( climate sensitivity ) , how global climate change will play out at local and regional scales , and what the consequences of global warming will be . Global warming remains an issue of widespread political debate , often split along party political lines , especially in the United States .

This condition is generally true in thermal conduction ( where it is guaranteed by Fourier 's law ) , but it is often only approximately true in conditions of convective heat transfer , where a number of physical processes make effective heat transfer coefficients somewhat dependent on temperature differences . Finally , in the case of heat transfer by thermal radiation , Newton 's law of cooling is not true . Sir Isaac Newton did not originally state his law in the above form in 1701 , when it was originally formulated . Rather , using today 's terms , Newton noted after some mathematical manipulation that the rate of temperature change of a body is proportional to the difference in temperatures between the body and its surroundings . This final simplest version of the law given by Newton himself , was partly due to confusion in Newton 's time between the concepts of heat and temperature , which would not be fully disentangled until much later . When stated in terms of temperature differences , Newton 's law ( with several further simplifying assumptions , such as a low Biot number and temperature-independent heat capacity ) results in a simple differential equation for temperature-difference as a function of time .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years . Global temperatures increased by 5 -- 8 ° C . The carbon dioxide was likely released in two pulses , the first lasting less than 2,000 years . Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon . Stratigraphic sections of rock from this period reveal numerous other changes . Fossil records for many organisms show major turnovers . For example , in the marine realm , a mass extinction of benthic foraminifera , a global expansion of subtropical dinoflagellates , and an appearance of excursion , planktic foraminifera and calcareous nanofossils all occurred during the beginning stages of PETM . On land , modern mammal orders ( including primates ) suddenly appear in Europe and in North America .

Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional : the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that `` Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely '' the highest in at least the past 1,300 years .

Sparseness of proxy records results in considerable uncertainty for earlier periods . Individual proxy records , such as tree ring widths and densities used in dendroclimatology , are calibrated against the instrumental record for the period of overlap . Networks of such records are used to reconstruct past temperatures for regions : tree ring proxies have been used to reconstruct Northern Hemisphere extratropical temperatures ( within the tropics trees do not form rings ) but are confined to land areas and are scarce in the Southern Hemisphere which is largely ocean . Wider coverage is provided by multiproxy reconstructions , incorporating proxies such as lake sediments , ice cores and corals which are found in different regions , and using statistical methods to relate these sparser proxies to the greater numbers of tree ring records .

The series was re-titled The New Temperatures Rising Show , and featured a new supporting cast : Sudie Bond , Barbara Cason , Jennifer Darling , Jeff Morrow , and John Dehner . Cleavon Little was the only returning member of the original cast . In this season , Lynde was presented as the penny-pinching chief of staff , with Bond as his nagging mother and owner of the hospital . The New Temperatures Rising Show ran for 13 episodes before being placed on hiatus in January 1974 due to poor ratings . It returned in July in yet another incarnation . Asher returned as producer and restored the series to its original format -- albeit with Lynde continuing in the lead .

In the current episode of global warming many such 15-year periods appear in the surface temperature record , along with robust evidence of the long-term warming trend ; climate is classically averaged over 30-year periods . Publicity has surrounded claims of a global warming hiatus during the period 1998 -- 2013 . The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend , and so subsequent annual temperatures gave the appearance of a hiatus : by January 2006 , it appeared to some that global warming had stopped or paused . A 2009 study showed that decades without warming were not exceptional , and in 2011 a study showed that if allowances were made for known variability , the rising temperature trend continued unabated . There was increased public interest in 2013 in the run-up to publication of the IPCC Fifth Assessment Report , and despite concerns that a 15-year period was too short to determine a meaningful trend , the IPCC included a section on a hiatus , which it defined as a much smaller increasing linear trend over the 15 years from 1998 to 2012 , than over the 60 years from 1951 to 2012 . Various studies examined possible causes of the short-term slowdown . Even though the overall climate system has continued to accumulate energy due to Earth 's positive energy budget , the available temperature readings at the Earth 's surface indicate slower rates of increase in surface warming than in the prior decade . Since measurements at the top of the atmosphere show that Earth is receiving more energy than it is radiating back into space , the retained energy should be producing warming in the Earth 's climate system . Research reported in July 2015 on an updated NOAA dataset casts doubt on the existence of a hiatus , and it finds no indication of a slowdown even in earlier years . Scientists working on other datasets welcomed this study , though they have expressed the view that the recent warming trend was less than in previous periods of the same length . Subsequently , a detailed study supports the conclusion that warming is continuing , but it also find there was less warming between 2001 and 2010 than climate models had predicted , and that this slowdown might be attributed to short-term variations in the Pacific decadal oscillation ( PDO ) , which was negative during that period . Another review finds `` no substantive evidence '' of a pause in global warming . A statistical study of global temperature data since 1970 concludes that the term ` hiatus ' or ` pause ' is not justified . Independent of these discussions about data and measurements for earlier years , 2015 turned out to be much warmer than any of the earlier years , already before El Niño conditions started . The warmth of 2015 largely ended any remaining scientific credibility of claims that the supposed `` hiatus '' since 1998 had any significance for the long-term warming trend . In January 2017 , a study published in the journal Science Advances cast further doubt on the existence of a recent pause , with more evidence that ocean temperatures have been underestimated . An April 2017 study found the data consistent with a steady warming trend globally since the 1970s , with fluctuations within the expected range of short term variability .", "qid": "457", "docid": "Global_warming_hiatus", "rank": 31, "score": 101977 }, { "content": "Title: Sea level rise Content: A sea level rise is an increase in the volume of water in the world 's oceans , resulting in an increase in global mean sea level .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change .

Glacier mass balance is the key determinant of the health of a glacier . If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance ; if the accumulation is less than the ablation , the glacier will retreat . Glaciers in retreat will have negative mass balances , and if they do not find an equilibrium between accumulation and ablation , will eventually disappear .

These graphs were publicised to explain the scientific findings of climatology , and in addition to scientific debate over the reconstructions , they have been the topic of political dispute . The issue is part of the global warming controversy and has been one focus of political responses to reports by the Intergovernmental Panel on Climate Change ( IPCC ) .

Mahlman , to describe the pattern this showed , envisaging a graph that is relatively flat to 1900 as forming an ice hockey stick 's `` shaft '' , followed by a sharp increase corresponding to the `` blade '' . A version of this graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , along with four other reconstructions supporting the same conclusion . The graph was publicised , and became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th-century warmth was exceptional .

Leaves of Dryas octopetala are occasionally abundant in the Late Glacial , often minerogenic-rich , like the lake sediments of Scandinavian lakes . The Younger Dryas saw a sharp decline in temperature over most of the northern hemisphere , at the end of the Pleistocene epoch , immediately before the current warmer Holocene . It was the most recent and longest of several interruptions to the gradual warming of the Earth 's climate since the severe Last Glacial Maximum , c. 27,000 to 24,000 calendar years BP . The change was relatively sudden , taking place in decades , and resulted in a decline of 2 to 6 degrees Celsius , advances of glaciers and drier conditions , over much of the temperate northern hemisphere . It is thought to have been caused by a decline in the strength of the Atlantic meridional overturning circulation , which transports warm water from the equator towards the North Pole , and which in turn is thought to have been caused by an influx of fresh cold water from North America into the Atlantic . The Younger Dryas was a period of climatic change , but the effects were complex and variable . In the southern hemisphere , and some areas of the north such as southeastern North America , there was a slight warming . The presence of a distinct cold period at the end of the Late Glacial interval has been known for a long time .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world . The latter effect is currently causing global warming , and `` climate change '' is often used to describe human-specific impacts .", "qid": "457", "docid": "History_of_climate_change_science", "rank": 70, "score": 90266 }, { "content": "Title: Global warming in Antarctica Content: The effects of global warming in Antarctica may include rising temperatures and increasing snow melt .", "qid": "457", "docid": "Global_warming_in_Antarctica", "rank": 71, "score": 90220 }, { "content": "Title: Tim Naish Content: Tim Naish is a New Zealand glaciologist .

As a consequence , high paleolatitudes in both hemispheres were much warmer than at present .

Earth's geologic temperature record includes many more examples of geologically rapid transitions between different climate states.Climate tipping points are of particular interest in reference to concerns about global warming in the modern era. Possible tipping point behaviour has been identified for the global mean surface temperature by studying self-reinforcing feedbacks and the past behavior of Earth's climate system. Self-reinforcing feedbacks in the carbon cycle and planetary reflectivity could trigger a cascading set of tipping points that lead the world into a hothouse climate state.Large-scale components of the Earth system that may pass a tipping point have been referred to as tipping elements.

Following John T. Hollin 's work ( 1962 ) suggesting that climatic warming and rising sea-level cause Antarctic ice shelves to retreat , Mercer postulated that the West Antarctic ice sheet , being grounded well below sea-level and terminating in floating ice shelves , was vulnerable to these changes and may have collapsed altogether during the last interglacial when Antarctica may have been warmer and sea-level may have been higher . In 1978 , in the science magazine Nature , Mercer pointed out that `` green-house '' warming from burning fossil fuel could have the same effect during the present interglacial . Two studies published 12 May 2014 confirm Mercer 's assumption . Climate scientist James Hansen has coined the term , `` John Mercer effect .

The series was developed for the network by William Asher and Harry Ackerman for Ashmont Productions and Screen Gems . Set in a fictional Washington , D.C. hospital , the series featured James Whitmore as a no-nonsense chief of staff , forced to deal with the outlandish antics of a young intern ( Cleavon Little ) and three nurses ( Joan Van Ark , Reva Rose , and Nancy Fox ) . For the first season , 26 episodes were produced and broadcast . In the second season , Whitmore was replaced in the lead role by comedian Paul Lynde , and Asher was replaced as producer by Duke Vincent and Bruce Johnson . The series was re-titled The New Temperatures Rising Show , and featured a new supporting cast : Sudie Bond , Barbara Cason , Jennifer Darling , Jeff Morrow , and John Dehner . Cleavon Little was the only returning member of the original cast .

The series was originally developed , produced , and occasionally directed by William Asher for Ashmont Productions and Screen Gems and premiered on September 12 , 1972 , in the time slot of Tuesday nights at 8:00 PM . The regular cast consisted of Cleavon Little as Dr. Jerry Noland , Joan Van Ark as Nurse Annie Carlisle , Reva Rose as Nurse Mildred `` Millie '' MacInerny , Nancy Fox as Student Nurse Ellen Turner , and James Whitmore as Dr. Vincent Campanelli . The premise of the series featured Campanelli as the no-nonsense chief-of-staff of Capitol General , a ( fictional ) Washington , D.C. hospital , who is forced to deal with the outlandish antics of Noland and the three nurses , whom Campanelli refers to as `` the four horsemen of aggravation '' . During its first season -- and first format -- 26 episodes were aired with the final one broadcast on . Reruns of the season 's episodes continued until September 4 , 1973 . Despite heavy competition in the ratings from Maude on CBS and Bonanza on NBC , Temperatures Rising did well enough in its first season to be renewed for a second . For this second season , John Mitchell , the head of Screen Gems , decided to replace James Whitmore with comedian Paul Lynde , whose own sitcom , The Paul Lynde Show ( also produced by William Asher for the 1972 -- 73 season ) was to be cancelled . Asher was against the change and declined to continue with Temperatures Rising , resulting in him being replaced as producer by Duke Vincent and Bruce Johnson .

These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century , with the instrumental temperature record by 2000 exceeding earlier temperatures . The term `` hockey stick graph '' was coined by the climatologist Jerry Mahlman , to describe the pattern shown by the ( MBH99 ) reconstruction , envisaging a graph that is relatively flat with a downward trend to 1900 as forming an ice hockey stick 's `` shaft '' followed by a sharp , steady increase corresponding to the `` blade '' portion . The reconstructions have featured in Intergovernmental Panel on Climate Change ( IPCC ) reports as evidence of global warming . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . Paleoclimatology dates back to the 19th century , and the concept of examining varves in lake beds and tree rings to track local climatic changes was suggested in the 1930s . In the 1960s , Hubert Lamb generalised from historical documents and temperature records of central England to propose a Medieval Warm Period from around 900 to 1300 , followed by Little Ice Age . This was the basis of a `` schematic diagram '' featured in the IPCC First Assessment Report of 1990 beside cautions that the medieval warming might not have been global . The use of indicators to get quantitative estimates of the temperature record of past centuries was developed , and by the late 1990s a number of competing teams of climatologists found indications that recent warming was exceptional . introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large scale reconstructions . Their study was featured in the IPCC Second Assessment Report of 1995 . In 1998 Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 with shading emphasising that uncertainties ( to two standard error limits ) were much greater in earlier centuries . independently produced a CPS reconstruction extending back for a thousand years , and ( MBH99 ) used the MBH98 methodology to extend their study back to 1000 . A version of the MBH99 graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , which also drew on Jones et al. 1998 and three other reconstructions to support the conclusion that , in the Northern Hemisphere , the 1990s was likely to have been the warmest decade and 1998 the warmest year during the past 1,000 years . The graph became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th century warmth was exceptional . In 2003 , as lobbying over the 1997 Kyoto Protocol intensified , a paper claiming greater medieval warmth was quickly dismissed by scientists in the Soon and Baliunas controversy . Later in 2003 , Stephen McIntyre and Ross McKitrick published disputing the data used in MBH98 paper . In 2004 Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 McIntyre and McKitrick published criticisms of the principal components analysis methodology as used in MBH98 and MBH99 . Their analysis was subsequently disputed by published papers including and which pointed to errors in the McIntyre and McKitrick methodology . Political disputes led to the formation of a panel of scientists convened by the National Research Council , their North Report in 2006 supported Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result . More than two dozen reconstructions , using various statistical methods and combinations of proxy records , support the broad consensus shown in the original 1998 hockey-stick graph , with variations in how flat the pre-20th century `` shaft '' appears . The 2007 IPCC Fourth Assessment Report cited 14 reconstructions , 10 of which covered 1,000 years or longer , to support its strengthened conclusion that it was likely that Northern Hemisphere temperatures during the 20th century were the highest in at least the past 1,300 years .

Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional : the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that `` Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely '' the highest in at least the past 1,300 years .

As of 2010 this broad pattern was supported by more than two dozen reconstructions , using various statistical methods and combinations of proxy records , with variations in how flat the pre-20th-century `` shaft '' appears . Sparseness of proxy records results in considerable uncertainty for earlier periods . Individual proxy records , such as tree ring widths and densities used in dendroclimatology , are calibrated against the instrumental record for the period of overlap . Networks of such records are used to reconstruct past temperatures for regions : tree ring proxies have been used to reconstruct Northern Hemisphere extratropical temperatures ( within the tropics trees do not form rings ) but are confined to land areas and are scarce in the Southern Hemisphere which is largely ocean . Wider coverage is provided by multiproxy reconstructions , incorporating proxies such as lake sediments , ice cores and corals which are found in different regions , and using statistical methods to relate these sparser proxies to the greater numbers of tree ring records . The `` Composite Plus Scaling '' ( CPS ) method is widely used for large-scale multiproxy reconstructions of hemispheric or global average temperatures ; this is complemented by Climate Field Reconstruction ( CFR ) methods which show how climate patterns have developed over large spatial areas , making the reconstruction useful for investigating natural variability and long-term oscillations as well as for comparisons with patterns produced by climate models . During the 1,900 years before the 20th century , it is likely that the next warmest period was from 950 to 1100 , with peaks at different times in different regions .

The Last Glacial Maximum and sea-level minimum occurred c. 21,000 years before present ( BP ) . Antarctic ice cores show gradual warming beginning 3000 years later . At about 14,700 BP , there was a large pulse of meltwater , identified as Meltwater pulse 1A , probably from either the Antarctic ice sheet or the Laurentide ice sheet . Meltwater pulse 1A produced a marine transgression that raised global sea level about 20 meters in two to five centuries and is thought to have influenced the start of the Bølling / Allerød interstadial , the major break with glacial cold in the Northern Hemisphere . Meltwater pulse 1A was followed in Antarctica and the Southern Hemisphere by a renewed cooling , the Antarctic Cold Reversal , in c. 14,500 BP , which lasted for two millennia -- an instance of warming causing cooling .

The altitude of the mesopause for many years was assumed to be at around 85 km ( 53 mi . ) , but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km .

It is due to a summer-to-winter circulation giving rise to upwelling at the summer pole and downwelling at the winter pole . Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause . In the mesosphere the summer-to-winter circulation is due to gravity wave dissipation , which deposits momentum against the mean east-west flow , resulting in a small north-south circulation . In recent years the mesopause has also been the focus of studies on global climate change associated with increases in CO2 . Unlike the troposphere , where greenhouse gases result in the atmosphere heating up , increased CO2 in the mesosphere acts to cool the atmosphere due to increased radiative emission . This results in a measurable effect - the mesopause should become cooler with increased CO2 .

The neoglaciation has no well-marked universal beginning : local conditions and ecological inertia affected the onset of detectably cooler ( and wetter ) conditions . Driven inexorably by the Milankovitch cycle , cooler summers in higher latitudes of North America , which would cease to completely melt the annual snowfall , were masked at first by the presence of the slowly disappearing continental ice sheets , which persisted long after the astronomically calculated moment of maximum summer warmth : `` the neoglaciation can be said to have begun when the cooling caught up with the warming '' , remarked E.

In physical terms , the closure temperature is the temperature at which a system has cooled so that there is no longer any significant diffusion of the parent or daughter isotopes out of the system and into the external environment . The concept 's initial mathematical formulation was presented in a seminal paper by Martin H. Dodson , `` Closure temperature in cooling geochronological and petrological systems '' in the journal Contributions to Mineralogy and Petrology , 1973 , with refinements to a usable experimental formulation by other scientists in later years . This temperature varies broadly among different minerals and also differs depending on the parent and daughter atoms being considered . It is specific to a particular material and isotopic system . The closure temperature of a system can be experimentally determined in the lab by artificially resetting sample minerals using a high-temperature furnace . As the mineral cools , the crystal structure begins to form and diffusion of isotopes slows . At a certain temperature , the crystal structure has formed sufficiently to prevent diffusion of isotopes . This temperature is what is known as blocking temperature and represents the temperature below which the mineral is a closed system to measurable diffusion of isotopes . The age that can be calculated by radiometric dating is thus the time at which the rock or mineral cooled to blocking temperature . These temperatures can also be determined in the field by comparing them to the dates of other minerals with well-known closure temperatures .

It is named after an indicator genus , the alpine-tundra wildflower Dryas octopetala . Leaves of Dryas octopetala are occasionally abundant in the Late Glacial , often minerogenic-rich , like the lake sediments of Scandinavian lakes . The Younger Dryas saw a sharp decline in temperature over most of the northern hemisphere , at the end of the Pleistocene epoch , immediately before the current warmer Holocene . It was the most recent and longest of several interruptions to the gradual warming of the Earth 's climate since the severe Last Glacial Maximum , c. 27,000 to 24,000 calendar years BP . The change was relatively sudden , taking place in decades , and resulted in a decline of 2 to 6 degrees Celsius , advances of glaciers and drier conditions , over much of the temperate northern hemisphere . It is thought to have been caused by a decline in the strength of the Atlantic meridional overturning circulation , which transports warm water from the equator towards the North Pole , and which in turn is thought to have been caused by an influx of fresh cold water from North America into the Atlantic . The Younger Dryas was a period of climatic change , but the effects were complex and variable . In the southern hemisphere , and some areas of the north such as southeastern North America , there was a slight warming . The presence of a distinct cold period at the end of the Late Glacial interval has been known for a long time . Paleobotanical and lithostratigraphic studies of Swedish and Danish bog and lake sites , e.g. the Allerød clay pit in Denmark , first recognized and described the Younger Dryas . The Younger Dryas is the youngest and longest of three stadials that resulted from typically abrupt climatic changes that took place over the last 16,000 calendar years . Within the Blytt-Sernander classification of north European climatic phases , the prefix ` Younger ' refers to the recognition that this original ` Dryas ' period was preceded by a warmer stage , the Allerød oscillation , which in turn was preceded by the Older Dryas around 14,000 calendar years BP . This is not securely dated , and estimates vary by 400 years , but it is generally accepted that it lasted around 200 years . In northern Scotland the glaciers were thicker and more extensive than during the Younger Dryas . The Older Dryas , in turn , is preceded by another warmer stage , the Bølling oscillation that separates it from a third and even older stadial . This stadial is often , but not always , known as the Oldest Dryas . The Oldest Dryas occurred approximately 1,770 calendar years before the Younger Dryas and lasted about 400 calendar years . According to the GISP2 ice core from Greenland , the Oldest Dryas occurred between about 15,070 and 14,670 calendar years BP . In Ireland , the Younger Dryas has also been known as the Nahanagan Stadial , while in Great Britain it has been called the Loch Lomond Stadial . In the Greenland Summit ice core chronology , the Younger Dryas corresponds to Greenland Stadial 1 ( GS-1 ) .

Today , it includes M-dwarf late-type stars , at the threshold of L4 dwarf stars . They form a heterogeneous group which includes stars of very low mass and brown dwarfs . Together , they represent about 15 % of astronomical objects in the stellar neighbourhood of the Sun . The accretion model suggests that , considering their low mass and the small size of their proto-planetary disks , these stars could host a relatively abundant population of Earth-like planets ranging from Mercury-size to Earth-size . The discovery of the TRAPPIST-1 system of seven Earth-like planets seems to validate this accretion model . Due to their slow hydrogen fusion compared to other types of low mass stars their life span is estimated to exceed a hundred billion years .

The first phase of the global heatwaves was caused by a moderate El Niño event, which lasted from June 2009 to May 2010. The first phase lasted only from April 2010 to June 2010, and caused only moderate above average temperatures in the areas affected. But it also set new record high temperatures for most of the area affected, in the Northern Hemisphere. The second phase (the main, and most devastating phase) was caused by a very strong La Niña event, which lasted from June 2010 to June 2011. According to meteorologists, the 2010–11 La Niña event was one of the strongest La Niña events ever observed. That same La Niña event also had devastating effects in the Eastern states of Australia. The second phase lasted from June 2010 to October 2010, caused severe heat waves, and multiple record-breaking temperatures. The heatwaves began on April 2010, when strong anticyclones began to develop, over most of the affected regions, in the Northern Hemisphere. The heatwaves ended in October 2010, when the powerful anticyclones over most of the affected areas dissipated. The heat wave during the summer of 2010 was at its worst in June, over the Eastern United States, Middle East, Eastern Europe and European Russia, and over Northeastern China and southeastern Russia. June 2010 marked the fourth consecutive warmest month on record globally, at 0.66 °C (1.22 °F) above average, while the period April–June was the warmest ever recorded for land areas in the Northern Hemisphere, at 1.25 °C (2.25 °F) above average. The previous record for the global average temperature in June was set in 2005 at 0.66 °C (1.19 °F), and the previous warm record for April–June over Northern Hemisphere land areas was 1.16 °C (2.09 °F), set in 2007. The strongest of the anticyclones, the one situated over Siberia, registered a maximum high pressure of 1040 millibars. The weather caused forest fires in China, where three in a team of 300 died fighting a fire that broke out in the Binchuan County of Dali, as Yunnan suffered the worst drought in 60 years by February 17. A major drought was reported across the Sahel as early as January. In August, a section of the Petermann Glacier tongue connecting northern Greenland, the Nares Strait and the Arctic Ocean broke off, the biggest ice shelf in the Arctic to detach in 48 years. By the time the heatwaves had ended in late October 2010, about $500 billion (2011 USD) of damage was done, in the Northern Hemisphere alone.

On Antarctica the deficiency increased by 75 % . Mountain glaciers are retreating and the cumulative mean thickness change has accelerated from about − 1.8 to − 4 m in 1965 to 1970 to about − 12 to − 14 m in the first decade of the 21st century . From 1961 to 2003 , ocean temperatures to a depth of 700 m increased and portions of the deeper ocean are warming .

Significant fossil trackway discoveries began almost immediately after the start of the 20th century with the 1900 discovery at Ipolytarnoc , Hungary of a wide variety of bird and mammal footprints left behind during the early Miocene . Not long after , fossil Iguanodon footprints were discovered in Sussex , England , a discovery that probably served as the inspiration for Sir Arthur Conan Doyle 's The Lost World . Several enduring mysteries from the 19th century continued to vex ichnologists , like the identity of the Chirotherium trackmaker . Renowned paleontologist Franz von Nopcsa attributed the ichnogenus to the prosauropod dinosaur Plateosaurus , despite an apparent mismatch between its number of toes ( 4 ) and the preserved digit traces of Chirotherium ( 5 ) . Von Nopcsa explained the discrepancy by arguing that one of the impressions in the Chirotherium tracks was left by a soft tissue structure that did not fossilize . However , it was Wolfgang Soergel who correctly hypothesized that Chirotherium was produced by a distant relative of modern crocodilians . Using only its footprints as a guide he reconstructed the life appearance of the Chirotherium trackmaker . Decades later paleontologists described an animal named Ticinosuchus which precisely fulfilling Soergel 's predictions . Ticinosuchus or a close relative seems to have been the true Chirotherium trackmaker . During the 20th century , many significant fossil trackway discoveries were made in the western United States . In the 1930s and 1940s , Roland T. Bird discovered the tracks of large sauropod and theropod dinosaurs in Texas . He excavated a major section of the track ways on behalf of the American Museum of Natural History . This was the first large scale excavation of fossil footprints in history . In the 1950s Lee Stokes reported unusual footprints he interpreted as the first known pterosaur tracks . This attribution would be controversial much of the rest of the century but has since been vindicated . The dinosaur footprints of Dinosaur Ridge in Colorado were also discovered and studied in the 20th century . The advent of the Dinosaur Renaissance and the publication by R. McNeil Alexander of a formula which could reconstruct their running speed based on data from fossil trackways brought renewed interest and prestige to ichnology during the late 20th century . This led to several symposia on the subject of vertebrate trace fossils . In 1986 such a conference dedicated to dinosaur footprints was held in New Mexico . Roughly a decade later renowned German ichnologist Heinrich Haubold organized a conference dedicated to the more ancient footprints of the Paleozoic Era . This gathering has been regarded as a turning point in the study of tracks of that age .", "qid": "463", "docid": "20th_century_in_ichnology", "rank": 7, "score": 85570 }, { "content": "Title: History of climate change science Content: The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect first identified . In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world . The latter effect is currently causing global warming , and `` climate change '' is often used to describe human-specific impacts .", "qid": "463", "docid": "History_of_climate_change_science", "rank": 8, "score": 83649 }, { "content": "Title: Water export Content: Water exports involve exporting freshwater from one country to another .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional : the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that `` Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely '' the highest in at least the past 1,300 years . '' The curve shown in graphs of these reconstructions is widely known as the hockey stick graph because of the sharp increase in temperatures during the last century . As of 2010 this broad pattern was supported by more than two dozen reconstructions , using various statistical methods and combinations of proxy records , with variations in how flat the pre-20th-century `` shaft '' appears . Sparseness of proxy records results in considerable uncertainty for earlier periods . Individual proxy records , such as tree ring widths and densities used in dendroclimatology , are calibrated against the instrumental record for the period of overlap . Networks of such records are used to reconstruct past temperatures for regions : tree ring proxies have been used to reconstruct Northern Hemisphere extratropical temperatures ( within the tropics trees do not form rings ) but are confined to land areas and are scarce in the Southern Hemisphere which is largely ocean . Wider coverage is provided by multiproxy reconstructions , incorporating proxies such as lake sediments , ice cores and corals which are found in different regions , and using statistical methods to relate these sparser proxies to the greater numbers of tree ring records . The `` Composite Plus Scaling '' ( CPS ) method is widely used for large-scale multiproxy reconstructions of hemispheric or global average temperatures ; this is complemented by Climate Field Reconstruction ( CFR ) methods which show how climate patterns have developed over large spatial areas , making the reconstruction useful for investigating natural variability and long-term oscillations as well as for comparisons with patterns produced by climate models . During the 1,900 years before the 20th century , it is likely that the next warmest period was from 950 to 1100 , with peaks at different times in different regions .

These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century , with the instrumental temperature record by 2000 exceeding earlier temperatures . The term `` hockey stick graph '' was coined by the climatologist Jerry Mahlman , to describe the pattern shown by the ( MBH99 ) reconstruction , envisaging a graph that is relatively flat with a downward trend to 1900 as forming an ice hockey stick 's `` shaft '' followed by a sharp , steady increase corresponding to the `` blade '' portion . The reconstructions have featured in Intergovernmental Panel on Climate Change ( IPCC ) reports as evidence of global warming . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . Paleoclimatology dates back to the 19th century , and the concept of examining varves in lake beds and tree rings to track local climatic changes was suggested in the 1930s . In the 1960s , Hubert Lamb generalised from historical documents and temperature records of central England to propose a Medieval Warm Period from around 900 to 1300 , followed by Little Ice Age . This was the basis of a `` schematic diagram '' featured in the IPCC First Assessment Report of 1990 beside cautions that the medieval warming might not have been global . The use of indicators to get quantitative estimates of the temperature record of past centuries was developed , and by the late 1990s a number of competing teams of climatologists found indications that recent warming was exceptional . introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large scale reconstructions . Their study was featured in the IPCC Second Assessment Report of 1995 . In 1998 Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 with shading emphasising that uncertainties ( to two standard error limits ) were much greater in earlier centuries . independently produced a CPS reconstruction extending back for a thousand years , and ( MBH99 ) used the MBH98 methodology to extend their study back to 1000 . A version of the MBH99 graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , which also drew on Jones et al. 1998 and three other reconstructions to support the conclusion that , in the Northern Hemisphere , the 1990s was likely to have been the warmest decade and 1998 the warmest year during the past 1,000 years . The graph became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th century warmth was exceptional . In 2003 , as lobbying over the 1997 Kyoto Protocol intensified , a paper claiming greater medieval warmth was quickly dismissed by scientists in the Soon and Baliunas controversy . Later in 2003 , Stephen McIntyre and Ross McKitrick published disputing the data used in MBH98 paper . In 2004 Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 McIntyre and McKitrick published criticisms of the principal components analysis methodology as used in MBH98 and MBH99 . Their analysis was subsequently disputed by published papers including and which pointed to errors in the McIntyre and McKitrick methodology . Political disputes led to the formation of a panel of scientists convened by the National Research Council , their North Report in 2006 supported Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result . More than two dozen reconstructions , using various statistical methods and combinations of proxy records , support the broad consensus shown in the original 1998 hockey-stick graph , with variations in how flat the pre-20th century `` shaft '' appears .

In 2013 , the CSIRO released a report stating that Australia is becoming hotter , and that it will experience more extreme heat and longer fire seasons because of climate change . In 2014 , the Bureau of Meteorology released a report on the state of Australia 's climate that highlighted several key points , including the significant increase in Australia 's temperatures ( particularly night-time temperatures ) and the increasing frequency of bush fires , droughts and floods , which have all been linked to climate change . Since the beginning of the 20th century Australia has experienced an increase of nearly 1 ° C in average annual temperatures , with warming occurring at twice the rate over the past 50 years than in the previous 50 years . Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the impacts of climate change in Australia . Rainfall in southwestern Australia has decreased by 10 -- 20 % since the 1970s , while southeastern Australia has also experienced a moderate decline since the 1990s . Rainfall patterns are expected to be problematic , as rain has become heavier and infrequent , as well as more common in summer rather than in winter , with little or no uptrend in rainfall in the Western Plateau and the Central Lowlands of Australia . Water sources in the southeastern areas of Australia have depleted due to increasing population in urban areas ( rising demand ) coupled with climate change factors such as persistent prolonged drought ( diminishing supply ) . At the same time , Australia continues to have the highest per capita greenhouse gas emissions . Temperatures in Australia have also risen dramatically since 1910 and nights have become warmer . A carbon tax was introduced in 2011 by the Gillard government in an effort to reduce the impact of climate change and despite some criticism , it successfully reduced Australia 's carbon dioxide emissions , with coal generation down 11 % since 2008 -- 09 . The subsequent Australian Government , elected in 2013 under then Prime Minister Tony Abbott was criticised for being `` in complete denial about climate change '' . Furthermore , the Abbott government repealed the carbon tax on 17 July 2014 in a heavily criticised move . The renewable energy target ( RET ) , launched in 2001 , was heavily modified under Abbott 's government . However , under the government of Malcolm Turnbull , Australia attended the 2015 United Nations Climate Change Conference and adopted the Paris Agreement . This agreement includes a review of emission reduction targets every 5 years from 2020 . The federal government and all state governments ( New South Wales , Victoria , Queensland , South Australia , Western Australia , Tasmania , Northern Territory and the Australian Capital Territory ) have explicitly recognised that climate change is being caused by greenhouse gas emissions , in conformity with the scientific opinion on climate change . Sectors of the population have campaigned against new coal mines and coal-fired power stations , reflecting concerns about the effects of global warming on Australia . The Garnaut Climate Change Review predicted that a net benefit to Australia may be derived by stabilising greenhouse gases in the atmosphere at 450ppm CO2 eq . The per-capita carbon footprint in Australia was rated 12th in the world by PNAS in 2011 , considerably large given the small population of the country .", "qid": "463", "docid": "Climate_change_in_Australia", "rank": 25, "score": 75262 }, { "content": "Title: Raymond S.

In terms of the Euro-American tradition , the main periods are captured in the bipartite division , Modernist literature and Postmodern literature , flowering from roughly 1900 to 1940 and 1960 to 1990 respectively , divided , as a rule of thumb , by World War II . The somewhat malleable term of contemporary literature is usually applied with a post-1960 cutoff point . Although these terms ( modern , contemporary and postmodern ) are most applicable to Western literary history , the rise of globalization has allowed European literary ideas to spread into non-Western cultures fairly rapidly , so that Asian and African literatures can be included into these divisions with only minor qualifications . And in some ways , such as in Postcolonial literature , writers from non-Western cultures were on the forefront of literary development . Technological advances during the 20th century allowed cheaper production of books , resulting in a significant rise in production of popular literature and trivial literature , comparable to the similar developments in music . The division of `` popular literature '' and `` high literature '' in the 20th century is by no means absolute , and various genres such as detectives or science fiction fluctuate between the two . Largely ignored by mainstream literary criticism for the most of the century , these genres developed their own establishments and critical awards ; these include the Nebula Award ( since 1965 ) , the British Fantasy Award ( since 1971 ) or the Mythopoeic Awards ( since 1971 ) . Towards the end of the 20th century , electronic literature developed due to the development of hypertext and later the world wide web . The Nobel Prize in Literature was awarded annually throughout the century ( with the exception of 1914 , 1918 , 1935 and 1940 -- 1943 ) , the first laureate ( 1901 ) being Sully Prudhomme .

Where the fact of evolutionary change was accepted but natural selection was denied , explanations of evolution such as Lamarckism , catastrophism , orthogenesis , vitalism , structuralism and mutationism ( called saltationism before 1900 ) were entertained . Different factors motivated people to propose non-Darwinian mechanisms of evolution . Natural selection , with its emphasis on death and competition , did not appeal to some naturalists because they felt it immoral , leaving little room for teleology or the concept of progress in the development of life . Some who came to accept evolution , but disliked natural selection , raised religious objections . Others felt that evolution was an inherently progressive process that natural selection alone was insufficient to explain . Still others felt that nature , including the development of life , followed orderly patterns that natural selection could not explain . By the start of the 20th century , evolution was generally accepted by biologists but natural selection was in eclipse . Many alternative theories were proposed , but biologists were quick to discount theories such as orthogenesis , vitalism and Lamarckism which offered no mechanism for evolution .

Historians of science such as Peter J. Bowler have used the same phrase as a label for the period within the history of evolutionary thought from the 1880s through the first couple of decades of the 20th century when a number of alternatives to natural selection were developed and explored -- as many biologists considered natural selection to have been a wrong guess on Charles Darwin 's part , and others regarded natural selection as of relatively minor importance . Recently the term eclipse has been criticized for inaccurately implying that research on Darwinism paused during this period , and Paul Farber and Mark Largent have suggested the biological term interphase as an alternative metaphor . While there had been multiple explanations of evolution including vitalism , catastrophism , and structuralism through the 19th century , four major alternatives to natural selection were in play at the turn of the 20th century : Theistic evolution was the belief that God directly guided evolution . ( This should not be confused with the more recent use of the term theistic evolution , referring to the theological belief about the compatibility of science and religion . ) The idea that evolution was driven by the inheritance of characteristics acquired during the life of the organism was called neo-Lamarckism . Orthogenesis involved the belief that organisms were affected by internal forces or laws of development that drove evolution in particular directions Saltationism propounded the idea that evolution was largely the product of large mutations that created new species in a single step . Theistic evolution largely disappeared from the scientific literature by the end of the 19th century as direct appeals to supernatural causes came to be seen as unscientific . The other alternatives had significant followings well into the 20th century ; mainstream biology largely abandoned them only when developments in genetics made them seem increasingly untenable , and when the development of population genetics and the modern evolutionary synthesis demonstrated the explanatory power of natural selection .

The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise .

This is the rare novel to have originated as an interactive installation that spawned related solo and group exhibitions prior to publication . What has evolved is a layered narrative that offers a literary alternative to gaming and other forms of media storytelling . In 2012 , Klein , who coined the term `` scripted space '' in 1998 , and Bistis coined `` wunder-roman '' to describe this alternative form . As described in the novel , this term references a mythical 19th-century version of the picaresque novel where the layers -- as story -- roll along a water wheel . Wunder-roman evokes the mental imagery of navigating the various components : the narrated media archive layered with sound or the comic historical novel with essays . Each component stands alone , but like the lyrics and music of an opera , they belong to each other . In the novel , the massive privately-held `` Carrie 's archive '' ( 1917-1936 ) contains 2000 + documents affixed to cards stored inside a circuitous room and mechanically accessible much like garments stored on dry-cleaner racks . Subscribers to the online package ( the archive and ebook of novel ) are granted access to these documents : `` photographs , films , comic illustrations , scientific and medical imagery , industrial designs , architectural drawings and ephemera like postcards , stereocards , and maps '' spanning 1885 to 1925 . The first documents , and the curatorial idea for The Imaginary 20th Century , evolved out of Bistis ' research for `` Comic Art : The Paris Salon in Caricature , '' a 2003 exhibition organized by the Getty Research Institute . Klein and Bistis started work on the project with support from California Institute of the Arts .

It is located at 595 Delaware Avenue , in the Delaware District neighborhood . It was the first club run by women , for women , in the United States . The club developed out of the Graduates Association of the Buffalo Seminary , spearheaded by Charlotte Mulligan , a teacher , writer , and musician from a well-to-do family . She envisioned a club rich in tradition , education , and culture . The Twentieth Century Club became noted for the many lavish social events held there , but education was , and still is , the primary focus of activity . Starting with an 1894 lecture on Abraham Lincoln , and continuing through the present , the Club has a long tradition of presenting prominent speakers and programs by recognized experts on a wide variety of subjects . From the 19th century , when women could n't vote and had limited opportunity , to today in the 21st century when possibilities seem limitless , the Twentieth Century Club has truly spanned its namesake century and connected those prior and succeeding . Its history parallels and chronicles not only the history of events in Buffalo , but also that of the enormous societal changes which have occurred in its lifespan . In 1894 , the club purchased the present property and hired the firm of Green & Wicks to design a clubhouse to add to the front of an existing Baptist church . The clubhouse is a three story building in the Italian renaissance style . The building is 78 feet wide and 96 feet deep .

Prior to the invention of mass market gramophone records ( developed in 1892 ) and radio broadcasting ( first commercially done ca. 1919 -- 20 ) , people mainly listened to music at live Classical music concerts or musical theatre shows , which were too expensive for many lower-income people ; on early phonograph players ( a technology invented in 1877 which was not mass-marketed until the mid-1890s ) ; or by individuals performing music or singing songs on an amateur basis at home , using sheet music , which required the ability to sing , play , and read music . These were skills that tended to be limited to middle-class and upper-class individuals . With the mass-market availability of gramophone records and radio broadcasts , listeners could purchase recordings of , or listen on radio to recordings or live broadcasts of a huge variety of songs and musical pieces from around the globe . This enabled a much wider range of the population to listen to performances of Classical music symphonies and operas that they would not be able to hear live , either due to not being able to afford live-concert tickets or because such music was not performed in their region . Sound recording was also a major influence on the development of popular music genres , because it enabled recordings of songs and bands to be inexpensively and widely distributed nationwide or even , for some artists , worldwide . The development of relatively inexpensive reproduction of music via a succession of formats including vinyl records , compact cassettes , compact discs ( introduced in 1983 ) and , by the mid-1990s , digital audio recordings , and the transmission or broadcast of audio recordings of music performances on radio , of video recordings or live performances on television , and by the 1990s , of audio and video recordings via the Internet , using file sharing of digital audio recordings , gave individuals from a wide range of socioeconomic classes access to a diverse selection of high-quality music performances by artists from around the world . The introduction of multitrack recording in 1955 and the use of mixing had a major influence on pop and rock music , because it enabled record producers to mix and overdub many layers of instrument tracks and vocals , creating new sounds that would not be possible in a live performance . The development of sound recording and audio engineering technologies and the ability to edit these recordings gave rise to new subgenres of classical music , including the Musique concrète ( 1949 ) and acousmatic ( 1955 ) schools of electronic composition . In the 1970s , African-American hip hop musicians began to use the record turntable as a musical instrument , creating rhythmic and percussive `` scratching '' effects by manipulating a vinyl record on the turntable . The 20th-century orchestra was far more flexible than its predecessors and used a much wider variety of instruments . In Beethoven 's and Felix Mendelssohn 's time in the 19th century , the orchestra was composed of a fairly standard core of instruments which was very rarely modified . As time progressed , and as the Romantic period saw changes in accepted modification with composers such as Berlioz and Mahler , the 20th century saw that instrumentation could practically be hand-picked by the composer . Saxophones were used in some 20th-century orchestra scores such as Vaughan Williams ' Symphonies No. 6 and 9 and William Walton 's Belshazzar 's Feast , and many other works as a member of the orchestral ensemble . Twentieth-century orchestras generally include a string section , woodwinds , brass instruments , percussion , piano , celeste , harp ( s ) , with other instruments called for occasionally , such as electric guitar and electric bass . The 20th century saw dramatic innovations in musical forms and styles . Composers and songwriters explored new forms and sounds that challenged the previously accepted rules of music of earlier periods , such as the use of altered chords and extended chords in 1940s-era Bebop jazz . The development of powerful , loud guitar amplifiers and sound reinforcement systems in the 1960s and 1970s permitted bands to hold large concerts where even those with the least expensive tickets could hear the show . Composers and songwriters experimented with new musical styles , such as genre fusions ( e.g. , the late 1960s fusion of jazz and rock music to create jazz fusion ) . As well , composers and musicians used new electric , electronic , and digital instruments and musical devices . In the 1980s , some styles of music , such as electronic dance music genres such as house music were created largely with synthesizers and drum machines . Faster modes of transportation such as jet flight allowed musicians and fans to travel more widely to perform or hear shows , which increased the spread of musical styles .", "qid": "463", "docid": "20th-century_music", "rank": 69, "score": 68119 }, { "content": "Title: 20th Century Limited Content: The 20th Century Limited was an express passenger train on the New York Central Railroad ( NYC ) from 1902 to 1967 , advertised as `` The Most Famous Train in the World '' .

The introduction of new materials ( and techniques ) and heretofore non-art materials helped drive change in art during the 20th century . Traditional materials and techniques were not necessarily displaced in the 20th century . Rather they functioned alongside innovations that came with the 20th century . Such mainstays as oil-on-canvas painting , and sculpting in traditional materials continued right through the 20th century into the 21st century . Furthermore , even `` traditional '' materials were greatly expanded in the course of the 20th century . The number of pigments available to artists ( painters , primarily ) has increased both in quantity and quality , by most reckoning . New formulations for traditional materials especially the commercial availability of acrylic paint have become widely used , introducing initial issues over their stability and longevity . Pablo Picasso , Georges Braque , Kurt Schwitters , Joseph Cornell and others incorporated paper collage and mixed drawing ( materials ) with paint to fashion their work . Both Picasso and Marcel Duchamp pioneered the use of found objects as material for paintings and sculpture during the 1910s . In the 1940s Jackson Pollock pioneered the use of housepaint , silver and aluminum paint , duco , and various objects for use in his paintings . In the 1950s Robert Rauschenberg included 3-D elements like tires and stuffed animals as well as using discarded materials like crushed or flattened cardboard boxes . Yves Klein incorporated live nude models and a symphony orchestra in his performance pieces of his paintings . John Chamberlain used crushed auto parts for sculpture . In the 1960s Pop artists Andy Warhol , Claes Oldenburg , Tom Wesselmann and Roy Lichtenstein made art from commercial products , or art that resembled commercial products like television sets , soup cans , brillo boxes , comic books , household furniture and restaurant items among other things . Edward Kienholz made replicas of actual environments both domestic and commercial , while George Segal made life-size plaster figures in settings using real objects and props . Dan Flavin used electric fluorescent lights and ballasts to create sculpture . In the 1970s Frank Stella introduced honeycombed aluminum and glitter . In the 1980s Julian Schnabel made `` plate paintings '' with broken crockery stuck to the surface and then painted over , Anselm Kiefer and Richard Long used mud , soil or tar in their works . In the 1960s and again in the 1990s artists used excrement notably - the Italian artist Piero Manzoni in 1961 and the British artist Chris Ofili who specialized in using elephant dung in the 1990s . Tracey Emin included her bed , entitled My Bed , in 1999 . Some innovations concerning materials used in art merely function in a supportive way , and other innovative materials are much more conspicuous . Frank Stella 's use of honeycombed aluminum served as a lightweight and strong and very configurable support for imagery .

Nineteenth-century movements of Post-Impressionism ( Les Nabis ) , Art Nouveau and Symbolism led to the first twentieth-century art movements of Fauvism in France and Die Brücke ( `` The Bridge '' ) in Germany . Fauvism in Paris introduced heightened non-representational colour into figurative painting . Die Brücke strove for emotional Expressionism . Another German group was Der Blaue Reiter ( `` The Blue Rider '' ) , led by Kandinsky in Munich , who associated the blue rider image with a spiritual non-figurative mystical art of the future . Kandinsky , Kupka , R. Delaunay and Picabia were pioneers of abstract ( or non-representational ) art . Cubism , generated by Picasso , Braque , Metzinger , Gleizes and others rejected the plastic norms of the Renaissance by introducing multiple perspectives into a two-dimensional image . Futurism incorporated the depiction of movement and machine age imagery . Dadaism , with its most notable exponents , Marcel Duchamp , who rejected conventional art styles altogether by exhibiting found objects , notably a urinal , and too Francis Picabia , with his Portraits Mécaniques . Parallel movements in Russia were Suprematism , where Kasimir Malevich also created non-representational work , notably a black canvas . The Jack of Diamonds group with Mikhail Larionov was expressionist in nature . Dadaism preceded Surrealism , where the theories of Freudian psychology led to the depiction of the dream and the unconscious in art in work by Salvador Dalí . Kandinsky 's introduction of non-representational art preceded the 1950s American Abstract Expressionist school , including Jackson Pollock , who dripped paint onto the canvas , and Mark Rothko , who created large areas of flat colour . Detachment from the world of imagery was reversed in the 1960s by the Pop Art movement , notably Andy Warhol , where brash commercial imagery became a Fine Art staple . Warhol also minimised the role of the artist , often employing assistants to make his work and using mechanical means of production , such as silkscreen printing . This marked a change from Modernism to Post-Modernism . Photorealism evolved from Pop Art and as a counter to Abstract Expressionists . Subsequent initiatives towards the end of the century involved a paring down of the material of art through Minimalism , and a shift toward non-visual components with Conceptual art , where the idea , not necessarily the made object , was seen as the art . The last decade of the century saw a fusion of earlier ideas in work by Jeff Koons , who made large sculptures from kitsch subjects , and in the UK , the Young British Artists , where Conceptual Art , Dada and Pop Art ideas led to Damien Hirst 's exhibition of a shark in formaldehyde in a vitrine .", "qid": "463", "docid": "20th-century_art", "rank": 85, "score": 66887 }, { "content": "Title: Faith and Fate Content: Faith and Fate : The Story of The Jewish People In The 20th Century is documentary about the Jewish people in the last century .

The modern synthesis solved difficulties and confusions caused by the specialisation and poor communication between biologists in the early years of the 20th century . At its heart was the question of whether Mendelian genetics could be reconciled with gradual evolution by means of natural selection . A second issue was whether the broad-scale changes of macroevolution seen by palaeontologists could be explained by changes seen in the microevolution of local populations . The synthesis included evidence from geneticists who studied populations in the field and in the laboratory . These studies were crucial to evolutionary theory .

During a pole 's winter , it lies in continuous darkness , chilling the surface and causing the deposition of 25 -- 30 % of the atmosphere into slabs of CO2 ice ( dry ice ) . When the poles are again exposed to sunlight , the frozen CO2 sublimes , creating enormous winds that sweep off the poles as fast as 400 km/h . These seasonal actions transport large amounts of dust and water vapor , giving rise to Earth-like frost and large cirrus clouds . Clouds of water-ice were photographed by the Opportunity rover in 2004 . The caps at both poles consist primarily of water ice . Frozen carbon dioxide accumulates as a comparatively thin layer about one metre thick on the north cap in the northern winter only , while the south cap has a permanent dry ice cover about 8 m thick . The northern polar cap has a diameter of about 1000 km during the northern Mars summer , and contains about 1.6 million cubic km of ice , which if spread evenly on the cap would be 2 km thick . ( This compares to a volume of 2.85 million cubic km ( km3 ) for the Greenland ice sheet . ) The southern polar cap has a diameter of 350 km and a thickness of 3 km . The total volume of ice in the south polar cap plus the adjacent layered deposits has also been estimated at 1.6 million cubic km . Both polar caps show spiral troughs , which recent analysis of SHARAD ice penetrating radar has shown are a result of roughly perpendicular katabatic winds that spiral due to the Coriolis Effect . The seasonal frosting of some areas near the southern ice cap results in the formation of transparent 1 m thick slabs of dry ice above the ground . With the arrival of spring , sunlight warms the subsurface and pressure from subliming CO2 builds up under a slab , elevating and ultimately rupturing it . This leads to geyser-like eruptions of CO2 gas mixed with dark basaltic sand or dust . This process is rapid , observed happening in the space of a few days , weeks or months , a rate of change rather unusual in geology -- especially for Mars . The gas rushing underneath a slab to the site of a geyser carves a spider-like pattern of radial channels under the ice .", "qid": "467", "docid": "Martian_polar_ice_caps", "rank": 2, "score": 152440 }, { "content": "Title: East Antarctic Ice Sheet Content: The East Antarctic Ice Sheet ( EAIS ) is one of two large ice sheets in Antarctica , and the largest on the entire planet .

Ice shelves are only found in Antarctica , Greenland , Canada and the Russian Arctic . The boundary between the floating ice shelf and the grounded ( resting on bedrock ) ice that feeds it is called the grounding line . The thickness of ice shelves ranges from about 100 to 1000 meters . In contrast , sea ice is formed on water , is much thinner ( typically less than 3m ) , and forms throughout the Arctic Ocean . It also is found in the Southern Ocean around the continent of Antarctica . Ice shelves are principally driven by gravity-driven pressure from the grounded ice . That flow continually moves ice from the grounding line to the seaward front of the shelf . The primary mechanism of mass loss from ice shelves was thought to have been iceberg calving , in which a chunk of ice breaks off from the seaward front of the shelf . A study by NASA and university researchers - published in the June 14 , 2013 issue of Science - found however that ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent 's ice shelf mass loss . Typically , a shelf front will extend forward for years or decades between major calving events . Snow accumulation on the upper surface and melting from the lower surface are also important to the mass balance of an ice shelf . Ice may also accrete onto the underside of the shelf . The density contrast between glacial ice , which is denser than normal ice , and liquid water means that only about 1/9 of the floating ice is above the ocean surface .

The only current ice sheets are in Antarctica and Greenland ; during the last glacial period at Last Glacial Maximum ( LGM ) the Laurentide ice sheet covered much of North America , the Weichselian ice sheet covered northern Europe and the Patagonian Ice Sheet covered southern South America . Ice sheets are bigger than ice shelves or alpine glaciers . Masses of ice covering less than 50,000 km2 are termed an ice cap . An ice cap will typically feed a series of glaciers around its periphery . Although the surface is cold , the base of an ice sheet is generally warmer due to geothermal heat . In places , melting occurs and the melt-water lubricates the ice sheet so that it flows more rapidly . This process produces fast-flowing channels in the ice sheet -- these are ice streams . The present-day polar ice sheets are relatively young in geological terms . The Antarctic Ice Sheet first formed as a small ice cap ( maybe several ) in the early Oligocene , but retreating and advancing many times until the Pliocene , when it came to occupy almost all of Antarctica . The Greenland ice sheet did not develop at all until the late Pliocene , but apparently developed very rapidly with the first continental glaciation .

Sea level rise is usually attributed to global climate change by thermal expansion of the water in the oceans and by melting of Ice sheets and glaciers on land . Melting of floating ice shelves or icebergs at sea raises sea levels only slightly . Sea level rise at specific locations may be more or less than the global average . Local factors might include tectonic effects , subsidence of the land , tides , currents , storms , etc. . Sea level rise is expected to continue for centuries . Because of the slow inertia , long response time for parts of the climate system , it has been estimated that we are already committed to a sea-level rise of approximately 2.3 m for each degree Celsius of temperature rise within the next 2,000 years .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world .

Soil survey geological evidences and lack of human occupation artefacts led scientists to formulate the claim that the Netherlands was largely underwater between the 3rd century and 1050 . This is the so-called third Dunkirk Transgression . The reality of the events , hypothetically determined by cyclical phases of strong sea level rises in historical times , is debated . The low-lying continental coast of Europe was lightly populated until c. 200 BC , when the climate and environment became more amenable to human habitation . Conditions remained favourable from 200 BC to 250 AD , and the region became densely populated . However the region had been undergoing a series of marine transgressions ( called Dunkirk 0 through Dunkirk IIIb ) characterised by a rising water table and floods that left layers of clay on the land . The heaviest blow came with the `` Dunkirk II transgression '' that began in the 3rd century and continually worsened , leaving large areas of the coast uninhabitable from c. 350 -- c. 700 .

The project was funded by the National Science Foundation as part of the International Decade of Ocean Exploration ( 1970s ) and is based in large part of the collection and analysis of a very large number of sediment cores to create a snapshot of conditions across the oceans . The CLIMAP project also resulted in maps of vegetative zones across the continents and the estimated extent of glaciation at the time . Most CLIMAP results aim to describe the Earth as it was 18 thousand years ago , but there was also an analysis to look at conditions during the previous interglacial -- 120 thousand years ago ( CLIMAP 1981 ) . CLIMAP has been a cornerstone of paleoclimate research and remains the most used sea surface temperature reconstruction of the global ocean during the last glacial maximum ( Yin and Battisti 2001 ) , but it has also been persistently controversial . CLIMAP resulted in estimates of global cooling of only 3.0 ± 0.6 ° C relative to the modern day ( Hoffert and Covey 1992 ) . The climate change during an ice age that occurs far from the continental ice sheets themselves is believed to be primarily controlled by changes in greenhouse gases , hence the conditions during the last glacial maximum provide a natural experiment for measuring the impact of changes in greenhouse gases on climate . The cited estimates of 3.0 ° C implies a climate sensitivity to carbon dioxide changes at the low end of the range proposed by the Intergovernmental Panel on Climate Change . However , CLIMAP also suggested that some of the tropics and in particular much of the Pacific Ocean were warmer than they are today . To date , no climate model has been able to reproduce the proposed warming in the Pacific ( Yin and Battisti 2001 ) , with most preferring a several degree cooling . Also , it appears that climate models which are forced to match the CLIMAP sea surface measurements are too warm to match estimates for changes at continental locations ( Pinot et al. 1999 ) . This suggests that either climate model design is missing some important unknown factor , or CLIMAP systematically overestimated the temperatures in the tropical oceans during the last glacial , though there is at present no consistent explanation for why or how this should have happened . Unfortunately cost and difficulty of collecting sediment cores from the open Pacific has limited the availability of samples that might help to confirm or disprove these observations . If the Pacific reconstruction is assumed to be in error , it would result in a larger climate sensitivity to changes in greenhouse gases .", "qid": "469", "docid": "Climate:_Long_range_Investigation,_Mapping,_and_Prediction", "rank": 24, "score": 94780 }, { "content": "Title: Sea Ice Physics and Ecosystem eXperiment Content: The Sea Ice Physics and Ecosystem eXperiment ( SIPEX ) was an Australian contribution to the International Polar Year ( IPY ) .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

In the current episode of global warming many such 15-year periods appear in the surface temperature record , along with robust evidence of the long-term warming trend ; climate is classically averaged over 30-year periods . Publicity has surrounded claims of a global warming hiatus during the period 1998 -- 2013 . The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend , and so subsequent annual temperatures gave the appearance of a hiatus : by January 2006 , it appeared to some that global warming had stopped or paused . A 2009 study showed that decades without warming were not exceptional , and in 2011 a study showed that if allowances were made for known variability , the rising temperature trend continued unabated . There was increased public interest in 2013 in the run-up to publication of the IPCC Fifth Assessment Report , and despite concerns that a 15-year period was too short to determine a meaningful trend , the IPCC included a section on a hiatus , which it defined as a much smaller increasing linear trend over the 15 years from 1998 to 2012 , than over the 60 years from 1951 to 2012 . Various studies examined possible causes of the short-term slowdown . Even though the overall climate system has continued to accumulate energy due to Earth 's positive energy budget , the available temperature readings at the Earth 's surface indicate slower rates of increase in surface warming than in the prior decade . Since measurements at the top of the atmosphere show that Earth is receiving more energy than it is radiating back into space , the retained energy should be producing warming in the Earth 's climate system . Research reported in July 2015 on an updated NOAA dataset casts doubt on the existence of a hiatus , and it finds no indication of a slowdown even in earlier years . Scientists working on other datasets welcomed this study , though they have expressed the view that the recent warming trend was less than in previous periods of the same length . Subsequently , a detailed study supports the conclusion that warming is continuing , but it also find there was less warming between 2001 and 2010 than climate models had predicted , and that this slowdown might be attributed to short-term variations in the Pacific decadal oscillation ( PDO ) , which was negative during that period . Another review finds `` no substantive evidence '' of a pause in global warming . A statistical study of global temperature data since 1970 concludes that the term ` hiatus ' or ` pause ' is not justified . Independent of these discussions about data and measurements for earlier years , 2015 turned out to be much warmer than any of the earlier years , already before El Niño conditions started . The warmth of 2015 largely ended any remaining scientific credibility of claims that the supposed `` hiatus '' since 1998 had any significance for the long-term warming trend . In January 2017 , a study published in the journal Science Advances cast further doubt on the existence of a recent pause , with more evidence that ocean temperatures have been underestimated . An April 2017 study found the data consistent with a steady warming trend globally since the 1970s , with fluctuations within the expected range of short term variability .", "qid": "469", "docid": "Global_warming_hiatus", "rank": 48, "score": 88299 }, { "content": "Title: Hockey stick controversy Content: In the hockey stick controversy , the data and methods used in reconstructions of the temperature record of the past 1000 years have been disputed . Reconstructions have consistently shown that the rise in the instrumental temperature record of the past 150 years is not matched in earlier centuries , and the name `` hockey stick graph '' was coined for figures showing a long-term decline followed by an abrupt rise in temperatures . These graphs were publicised to explain the scientific findings of climatology , and in addition to scientific debate over the reconstructions , they have been the topic of political dispute . The issue is part of the global warming controversy and has been one focus of political responses to reports by the Intergovernmental Panel on Climate Change ( IPCC ) . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . The use of proxy indicators to get quantitative estimates of the temperature record of past centuries was developed from the 1990s onwards , and found indications that recent warming was exceptional . The reconstruction introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large-scale reconstructions , and its findings were disputed by Patrick Michaels at the United States House Committee on Science . In 1998 , Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 . In ( MBH99 ) the methodology was extended back to 1000 . The term hockey stick was coined by the climatologist Jerry D. Mahlman , to describe the pattern this showed , envisaging a graph that is relatively flat to 1900 as forming an ice hockey stick 's `` shaft '' , followed by a sharp increase corresponding to the `` blade '' . A version of this graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , along with four other reconstructions supporting the same conclusion . The graph was publicised , and became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th-century warmth was exceptional . Those disputing the graph included Pat Michaels , the George C. Marshall Institute and Fred Singer . A paper by Willie Soon and Sallie Baliunas claiming greater medieval warmth was used by the Bush administration chief of staff Philip Cooney to justify altering the first Environmental Protection Agency Report on the Environment . The paper was quickly dismissed by scientists in the Soon and Baliunas controversy , but on July 28 , Republican Jim Inhofe spoke in the Senate citing it to claim `` that man-made global warming is the greatest hoax ever perpetrated on the American people '' . Later in 2003 , a paper by Steve McIntyre and Ross McKitrick disputing the data used in MBH98 paper was publicised by the George C. Marshall Institute and the Competitive Enterprise Institute . In 2004 , Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 , McIntyre and McKitrick published criticisms of the principal component analysis methodology as used in MBH98 and MBH99 . The analysis therein was subsequently disputed by published papers , including and , which pointed to errors in the McIntyre and McKitrick methodology . In June 2005 , Rep. Joe Barton launched what Sherwood Boehlert , chairman of the House Science Committee , called a `` misguided and illegitimate investigation '' into the data , methods and personal information of Mann , Bradley and Hughes . At Boehlert 's request , a panel of scientists convened by the National Research Council was set up , which reported in 2006 , supporting Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result . Barton and U.S. Rep. Ed Whitfield requested Edward Wegman to set up a team of statisticians to investigate , and they supported McIntyre and McKitrick 's view that there were statistical failings , although they did not quantify whether there was any significant effect . They also produced an extensive network analysis which has been discredited by expert opinion and found to have issues of plagiarism . Arguments against the MBH studies were reintroduced as part of the Climatic Research Unit email controversy , but dismissed by eight independent investigations . More than two dozen reconstructions , using various statistical methods and combinations of proxy records , have supported the broad consensus shown in the original 1998 hockey-stick graph , with variations in how flat the pre-20th century `` shaft '' appears . The 2007 IPCC Fourth Assessment Report cited 14 reconstructions , 10 of which covered 1,000 years or longer , to support its strengthened conclusion that it was likely that Northern Hemisphere temperatures during the 20th century were the highest in at least the past 1,300 years .

The Sea once included lands in what are now the Canadian provinces of Quebec and Ontario , as well as parts of the American states of New York and Vermont . The mass of ice from the continental ice sheets had depressed the rock beneath it over millennia . At the end of the last ice age , while the rock was still depressed , the Saint Lawrence and Ottawa River valleys , as well as modern Lake Champlain , were below sea level and flooded with rising worldwide sea levels , once the ice no longer prevented the ocean from flowing into the region . As the land gradually rose again , in the process known as isostatic rebound , the sea coast gradually retreated to its current location . The sea lasted from about 13,000 years ago to about 10,000 years ago and was continuously shrinking during that time , since the rebounding continent was slowly rising above sea level . At its peak , the sea extended inland as far south as Lake Champlain and somewhat farther west than the city of Ottawa , Ontario , and farther up the Ottawa River past Pembroke . The remaining glaciers fed the sea during that time , making it more brackish than typical seawater . It is estimated that the sea was as much as 150 m above the level of today 's Saint Lawrence and Ottawa Rivers . The best evidence of this former sea is the vast clay plain deposited along the Ottawa and St. Lawrence Rivers . This resulted in distinctive forest types , and large wetlands . Other modern evidence of the sea can be seen in the form of whale fossils , ( belugas , fin whales , and bowhead whales ) and marine shells that have been found near the cities of Ottawa , Ontario , and Montreal , Quebec . There are also fossils of oceanic fish such as capelin . The Sea also left ancient raised shorelines in the former coastal regions , and the Leda clay deposits in areas of deeper water .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years . Global temperatures increased by 5 -- 8 ° C . The carbon dioxide was likely released in two pulses , the first lasting less than 2,000 years . Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon . Stratigraphic sections of rock from this period reveal numerous other changes . Fossil records for many organisms show major turnovers . For example , in the marine realm , a mass extinction of benthic foraminifera , a global expansion of subtropical dinoflagellates , and an appearance of excursion , planktic foraminifera and calcareous nanofossils all occurred during the beginning stages of PETM .

Meltwater pulse 1A produced a marine transgression that raised global sea level about 20 meters in two to five centuries and is thought to have influenced the start of the Bølling / Allerød interstadial , the major break with glacial cold in the Northern Hemisphere . Meltwater pulse 1A was followed in Antarctica and the Southern Hemisphere by a renewed cooling , the Antarctic Cold Reversal , in c. 14,500 BP , which lasted for two millennia -- an instance of warming causing cooling .

Mercer ( Cheltenham , England , 19 October 1922 -- Columbus , Ohio 3 July 1987 ) was a glaciologist , chiefly known for his theoretical work on , and field studies of Antarctic ice streams , especially in the Transantarctic Mountains and in West Antarctica . Following John T. Hollin 's work ( 1962 ) suggesting that climatic warming and rising sea-level cause Antarctic ice shelves to retreat , Mercer postulated that the West Antarctic ice sheet , being grounded well below sea-level and terminating in floating ice shelves , was vulnerable to these changes and may have collapsed altogether during the last interglacial when Antarctica may have been warmer and sea-level may have been higher . In 1978 , in the science magazine Nature , Mercer pointed out that `` green-house '' warming from burning fossil fuel could have the same effect during the present interglacial . Two studies published 12 May 2014 confirm Mercer 's assumption . Climate scientist James Hansen has coined the term , `` John Mercer effect . '' After Mercer published his paper suggesting that the West Antarctic ice sheet could collapse in response to warming , he struggled to get funding . Others , including Hansen , had similar problems . Many climate scientists censor their own work to avoid losing funding , especially regarding prospects for limiting warming to 2 ° C above pre-industrial temperatures . John H. Mercer was the third child of Harriet and John W. Mercer . He was educated at private schools in Cheltenham and , later , at Gordonstoun in Scotland . During World War II he served in the British Merchant Marines ( 1940 -- 46 ) as a radio man . After the war he went to University of Cambridge and studied geography . At that time he came under the influence of William Vaughan Lewis . After finishing his B.A. in 1949 Mercer went to Canada , where he received his PhD in geography from McGill University in 1954 . He was a Research Scholar from 1954 to 1956 at the Australian National University in Canberra , where he studied land use and population in western Samoa . He returned to Canada and worked in the Canadian Hydro-graphic Office in Ottawa as a geographer in 1957 and 1958 . During 1959 -- 60 , 1961 -- 62 , 1964 , and 1966 , the American Geographical Society employed him at its World Data Center A for Glaciology in New York . The turning point in his career as a glaciologist was in 1960 , when he became a Research Associate at The Ohio State University , in the Institute of Polar Studies ( renamed the Byrd Polar Research Center ) .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation .

In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores . Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years . There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere .

Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass . Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth 's oceans .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change .

TOGA emphasized the tropical oceans and their relationship to the global atmosphere . Underlying TOGA is the premise that the dynamic adjustment of the ocean in the tropics is far more rapid than at higher latitudes . Thus disturbances emanating from the western Pacific Ocean ( such as El Niño ) may propagate across the basin on time scales of weeks compared to years for corresponding basin-wide propagation at higher latitudes . The significance of shorter dynamic times scales near the equator is that they are similar to those of highly energetic atmospheric modes . This similarity allows the formation of coupled modes between the ocean and the atmosphere .

In the current episode of global warming many such 15-year periods appear in the surface temperature record , along with robust evidence of the long-term warming trend ; climate is classically averaged over 30-year periods . Publicity has surrounded claims of a global warming hiatus during the period 1998 -- 2013 . The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend , and so subsequent annual temperatures gave the appearance of a hiatus : by January 2006 , it appeared to some that global warming had stopped or paused . A 2009 study showed that decades without warming were not exceptional , and in 2011 a study showed that if allowances were made for known variability , the rising temperature trend continued unabated . There was increased public interest in 2013 in the run-up to publication of the IPCC Fifth Assessment Report , and despite concerns that a 15-year period was too short to determine a meaningful trend , the IPCC included a section on a hiatus , which it defined as a much smaller increasing linear trend over the 15 years from 1998 to 2012 , than over the 60 years from 1951 to 2012 . Various studies examined possible causes of the short-term slowdown . Even though the overall climate system has continued to accumulate energy due to Earth 's positive energy budget , the available temperature readings at the Earth 's surface indicate slower rates of increase in surface warming than in the prior decade . Since measurements at the top of the atmosphere show that Earth is receiving more energy than it is radiating back into space , the retained energy should be producing warming in the Earth 's climate system . Research reported in July 2015 on an updated NOAA dataset casts doubt on the existence of a hiatus , and it finds no indication of a slowdown even in earlier years . Scientists working on other datasets welcomed this study , though they have expressed the view that the recent warming trend was less than in previous periods of the same length . Subsequently , a detailed study supports the conclusion that warming is continuing , but it also find there was less warming between 2001 and 2010 than climate models had predicted , and that this slowdown might be attributed to short-term variations in the Pacific decadal oscillation ( PDO ) , which was negative during that period . Another review finds `` no substantive evidence '' of a pause in global warming . A statistical study of global temperature data since 1970 concludes that the term ` hiatus ' or ` pause ' is not justified . Independent of these discussions about data and measurements for earlier years , 2015 turned out to be much warmer than any of the earlier years , already before El Niño conditions started . The warmth of 2015 largely ended any remaining scientific credibility of claims that the supposed `` hiatus '' since 1998 had any significance for the long-term warming trend . In January 2017 , a study published in the journal Science Advances cast further doubt on the existence of a recent pause , with more evidence that ocean temperatures have been underestimated . An April 2017 study found the data consistent with a steady warming trend globally since the 1970s , with fluctuations within the expected range of short term variability .", "qid": "470", "docid": "Global_warming_hiatus", "rank": 48, "score": 101608 }, { "content": "Title: International Comprehensive Ocean-Atmosphere Data Set Content: The International Comprehensive Ocean-Atmosphere Data Set ( ICOADS ) is a digital database of 261 million weather observations made by ships , weather ships , and weather buoys spanning the years 1662 to 2007 .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years . Global temperatures increased by 5 -- 8 ° C . The carbon dioxide was likely released in two pulses , the first lasting less than 2,000 years . Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon .

In the time since the industrial revolution the climate has increasingly been affected by human activities that are causing global warming and climate change.The climate system receives nearly all of its energy from the sun. The climate system also radiates energy to outer space. The balance of incoming and outgoing energy, and the passage of the energy through the climate system, determines Earth's energy budget. When the incoming energy is greater than the outgoing energy, earth's energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and earth experiences cooling. The energy moving through Earth's climate system finds expression in weather, varying on geographic scales and time. Long-term averages and variability of weather in a region constitute the region's climate. Such changes can be the result of \"internal variability\", when natural processes inherent to the various parts of the climate system alter the distribution of energy. Examples include variability in ocean basins such as the Pacific decadal oscillation and Atlantic multidecadal oscillation. Climate variability can also result from external forcing, when events outside of the climate system's components nonetheless produce changes within the system.

SOLAS has three major focus areas : Biogeochemical interactions and feedbacks between ocean and atmosphere , Exchange processes at the air-sea interface and the role of transport and transformation in the atmospheric and oceanic boundary layers , and Air-sea flux of carbon dioxide and other long-lived radiatively active gases ( this last focus is developed jointly with the Integrated Marine and Biogeochemistry and Ecosystem Research project ; IMBER ) . These three focuses are detailed in the project 's Science Plan and Implementation Strategy and in three separate Implementation Plans , and each focus has its own Implementation Working Group . The project is administered by a panel of scientific experts in the Scientific Steering Committee , and project coordination is handled by the SOLAS International Project Office at the University of East Anglia in Norwich UK . Scientific research is conducted by nations across the globe , and SOLAS has 23 established National Networks . SOLAS runs a successful biennial International Summer School , held at the Institut d'Etudes Scientifiques de Cargèse in Corsica France , and the next Summer School is scheduled for 2007 . Communications from SOLAS include a monthly e-bulletin , a biannual newsletter , and a website .

While these systems are highly common in the United States and China , the National Oceanic and Atmospheric Administration ( NOAA ) names Australia the most conducive environment after 30 years of research . In Australia such storm systems are called agukabams . One source of the brown ocean effect has been identified as the large amount of latent heat that can be released from extremely wet soils . A 2013 NASA study found that , from 1979-2008 , 45 of 227 tropical storms either gained or maintained strength after making landfall . The press release stated , `` The land essentially mimics the moisture-rich environment of the ocean , where the storm originated . '' Originally , countless research devoted to extratropical cyclones , storms that first derive energy from the warm ocean waters and later from the conjecture of various air masses , explained the intensification of storms after landfall . However , as research into these storms persists , Anderson and Shepherd , the two leading scientists behind the NASA study , discovered that some of these storms were not transitioning from warm-core to cold-core but were actually maintaining their warm-core dynamics , while ultimately outputting a greater measure of rainfall . In order for the brown ocean effect to take place , three land conditions must be met : `` First , the lower level of the atmosphere mimics a tropical atmosphere with minimal variation in temperature . Second , soils in the vicinity of the storms need to contain ample moisture . Finally , evaporation of the soil moisture releases latent heat , which the team found must measure at least 70 watts averaged per square meter . '' Storm systems impacted by the brown ocean effect gave rise to a new sub-category of tropical storm type called Tropical Cyclone Maintenance and Intensification Event or TCMI . Another study concluded that latent surface heat flux from land surfaces actually have the potential to be larger than from the ocean , albeit for brief periods only . Anderson and Shepherd are also examining the effects of climate change on TCMIs , looking into the potential intensification of these storms due to increase or decrease in the degree of wetness and dryness in areas susceptible to these systems .", "qid": "470", "docid": "Brown_ocean_effect", "rank": 70, "score": 97229 }, { "content": "Title: NRLMSISE-00 Content: NRLMSISE-00 is an empirical , global model of the Earth 's atmosphere from ground to space .

Although Mars is smaller than the Earth , at 11 % of Earth 's mass , and 50 % farther from the Sun than the Earth , its climate has important similarities , such as the polar ice caps , seasonal changes and the observable presence of weather patterns . It has attracted sustained study from planetologists and climatologists . While Mars 's climate has similarities to Earth 's , including periodic ice ages , there are also important differences , such as much lower thermal inertia . Mars ' atmosphere has a scale height of approximately 11 km , 60 % greater than that on Earth . The climate is of considerable relevance to the question of whether life is or was present on the planet . The climate briefly received more interest in the news due to NASA measurements indicating increased sublimation of the south polar icecap leading to some popular press speculation that Mars was undergoing a parallel bout of global warming , although Mars ' average temperature has actually cooled in recent decades . Mars has been studied by Earth-based instruments since the 17th century but it is only since the exploration of Mars began in the mid-1960s that close-range observation has been possible . Flyby and orbital spacecraft have provided data from above , while direct measurements of atmospheric conditions have been provided by a number of landers and rovers . Advanced Earth orbital instruments today continue to provide some useful `` big picture '' observations of relatively large weather phenomena . The first Martian flyby mission was Mariner 4 which arrived in 1965 . That quick two-day pass ( July 14 -- 15 , 1965 ) was limited and crude in terms of its contribution to the state of knowledge of Martian climate . Later Mariner missions ( Mariner 6 , and Mariner 7 ) filled in some of the gaps in basic climate information . Data-based climate studies started in earnest with the Viking program in 1975 and continues with such probes as the Mars Reconnaissance Orbiter . This observational work has been complemented by a type of scientific computer simulation called the Mars general circulation model .

Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional : the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that `` Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely '' the highest in at least the past 1,300 years .

As of 2010 this broad pattern was supported by more than two dozen reconstructions , using various statistical methods and combinations of proxy records , with variations in how flat the pre-20th-century `` shaft '' appears . Sparseness of proxy records results in considerable uncertainty for earlier periods . Individual proxy records , such as tree ring widths and densities used in dendroclimatology , are calibrated against the instrumental record for the period of overlap . Networks of such records are used to reconstruct past temperatures for regions : tree ring proxies have been used to reconstruct Northern Hemisphere extratropical temperatures ( within the tropics trees do not form rings ) but are confined to land areas and are scarce in the Southern Hemisphere which is largely ocean . Wider coverage is provided by multiproxy reconstructions , incorporating proxies such as lake sediments , ice cores and corals which are found in different regions , and using statistical methods to relate these sparser proxies to the greater numbers of tree ring records .

His work on these schemes led to the so-called `` Bryan-Cox code '' with which many early simulations were made , and which led to the Modular Ocean Model currently used by many numerical oceanographers and climate scientists . In addition to his important contributions in developing numerical codes , Bryan was also involved in early efforts to apply them to understanding the global climate system . In 1967 , he published , with Michael Cox , the first model of the 3-dimensional circulation of the ocean , forced by both winds and thermodynamic forcing . In 1969 , a paper with Syukoro Manabe was the first to present integrations of a fully coupled atmosphere-ocean model , demonstrating the importance of ocean heat transport to the climate . This work was recently named one of the top ten breakthroughs in the history of the National Oceanographic and Atmospheric Administration .

Southern Oscillation is the accompanying atmospheric component , coupled with the sea temperature change : El Niño is accompanied with high , and La Niña with low air surface pressure in the tropical western Pacific . The two periods last several months each ( typically occur every few years ) and their effects vary in intensity . The two phases relate to the Walker circulation , discovered by Gilbert Walker during the early twentieth century . The Walker circulation is caused by the pressure gradient force that results from a high pressure system over the eastern Pacific Ocean , and a low pressure system over Indonesia . When the Walker circulation weakens or reverses , an El Niño results , causing the ocean surface to be warmer than average , as upwelling of cold water occurs less or not at all . An especially strong Walker circulation causes a La Niña , resulting in cooler ocean temperatures due to increased upwelling . Mechanisms that cause the oscillation remain under study .

It had no official bounds ; it ran year-round in 1975 , but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December . These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean . The scope of this article is limited to the Pacific Ocean , north of the equator and west of the international date line . Storms that form east of the date line and north of the equator are called hurricanes ; see 1975 Pacific hurricane season .

Storm tracks are the relatively narrow zones in seas and oceans where storms travel driven by the prevailing winds . The Atlantic and Pacific have storm tracks along which most Atlantic or Pacific extratropical cyclones or tropical cyclones travel . The storm tracks usually begin in the westernmost parts of Atlantic and Pacific , where the large temperature contrasts between land and sea cause cyclones to form , particularly in winter . Surface friction cause these cyclones to quickly fill up and decay as soon as they reach land at the eastern end of the basins , accounting for the easternmost edges of the storm tracks . Storm tracks can shift position , causing important climatic patterns . As an example , during La Niña the Atlantic storm track shifts north causing droughts in Israel , while during El Niño it shifts south bringing heavy rains to the same region . Another example of a storm track is the circumpolar storm track in the Antarctic , however land-sea contrasts play no role in its formation .

Despite rather favorable conditions , the initial tropical depression did not intensify significantly and degenerated into a remnant low on August 18 . However , these remnants were able to reorganize and the system was reclassified as a tropical cyclone a day later . Intensification was rather rapid upon the storm 's reformation -- the depression reached tropical storm status on August 20 and then typhoon intensity two days later .

This was partially attributed to a La Niña -- a meteorological phenomenon that produces favorable conditions across the Atlantic basin , such as lower wind shear and higher sea surface temperatures . The first storm , Ana , developed on July 15 near Bermuda and caused minor effects in Canada while transitioning into an extratropical cyclone .

However , she was commonly referred to by her nickname , La Niña , which was probably a pun on the name of her owner , Juan Niño of Moguer . She was a standard caravel-type vessel . The other ships of the Columbus expedition were the caravel-type and the carrack-type . Niña was by far Columbus 's favorite . She was originally lateen sail rigged caravela latina , but she was re-rigged as caravela redonda at Las Palmas , in the Canary Islands , with square sails for better ocean performance .

Ocean water differs in temperature and salinity . Warm surface water is generally saltier than the cooler deep or polar waters ; in polar regions , the upper layers of ocean water are cold and fresh . Deep ocean water makes up about 90 % of the volume of the oceans . Deep ocean water has a very uniform temperature , around 0-3 ° C , and a salinity of about 3.5 % or as oceanographers state as 35 ppt ( parts per thousand ) . In specialized locations such as the Natural Energy Laboratory of Hawaii NELHA ocean water is pumped to the surface from approximately 900 metres ( 3000 feet ) deep for applications in research , commercial and pre-commercial activities . DOW is typically used to describe ocean water at sub-thermal depths sufficient to provide a measurable difference in water temperature . When deep ocean water is brought to the surface , it can be used for a variety of things . Its most useful property is its temperature . At the surface of the Earth , most water and air is well above 3 ° C . The difference in temperature is indicative of a difference in energy . Where there is an energy gradient , skillful application of science and engineering can harness that energy for productive use by humans . Assuming the source of deep ocean water is environmentally friendly and replenished by natural mechanisms , it forms a more innovative basis for cleaner energy than current fossil-fuel-derived energy . The simplest use of cold water is for air conditioning : using the cold water itself to cool air saves the energy that would be used by the compressors for traditional refrigeration . Another use could be to replace expensive desalination plants . When cold water passes through a pipe surrounded by humid air , condensation results . The condensate is pure water , suitable for humans to drink or for crop irrigation .

Water flowing northward becomes modified through evaporation and mixing with other water masses , leading to increased salinity . When this water reaches the North Atlantic it cools and sinks through convection , due to its decreased temperature and increased salinity resulting in increased density . NADW is the outflow of this thick deep layer , which can be detected by its high salinity , high oxygen content , nutrient minima , and chlorofluorocarbons ( CFCs ) . CFCs are anthropogenic substances that enter the surface of the ocean from gas exchange with the atmosphere .

The subtropical ridge is characterized by mostly calm winds , which act to reduce air quality under its axis by causing fog overnight , and haze during daylight hours as a result of the stable atmosphere found near its location . The air descending from the upper troposphere flows out from its center at surface level toward the upper and lower latitudes of each hemisphere , creating both the trade winds and the westerlies .

Ice shelves are only found in Antarctica , Greenland , Canada and the Russian Arctic . The boundary between the floating ice shelf and the grounded ( resting on bedrock ) ice that feeds it is called the grounding line . The thickness of ice shelves ranges from about 100 to 1000 meters . In contrast , sea ice is formed on water , is much thinner ( typically less than 3m ) , and forms throughout the Arctic Ocean . It also is found in the Southern Ocean around the continent of Antarctica . Ice shelves are principally driven by gravity-driven pressure from the grounded ice . That flow continually moves ice from the grounding line to the seaward front of the shelf . The primary mechanism of mass loss from ice shelves was thought to have been iceberg calving , in which a chunk of ice breaks off from the seaward front of the shelf . A study by NASA and university researchers - published in the June 14 , 2013 issue of Science - found however that ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent 's ice shelf mass loss . Typically , a shelf front will extend forward for years or decades between major calving events . Snow accumulation on the upper surface and melting from the lower surface are also important to the mass balance of an ice shelf . Ice may also accrete onto the underside of the shelf .

The properties of the ice and the recrystallized inclusions within the ice can then be used to reconstruct a climatic record over the age range of the core , normally through isotopic analysis . This enables the reconstruction of local temperature records and the history of atmospheric composition . Ice cores contain an abundance of information about climate . Inclusions in the snow of each year remain in the ice , such as wind-blown dust , ash , pollen , bubbles of atmospheric gas and radioactive substances . The variety of climatic proxies is greater than in any other natural recorder of climate , such as tree rings or sediment layers . These include ( proxies for ) temperature , ocean volume , precipitation , chemistry and gas composition of the lower atmosphere , volcanic eruptions , solar variability , sea-surface productivity , desert extent and forest fires . The length of the record depends on the depth of the ice core and varies from a few years up to 800 kyr ( 800,000 years ) for the EPICA core . The time resolution ( i.e. the shortest time period which can be accurately distinguished ) depends on the amount of annual snowfall , and reduces with depth as the ice compacts under the weight of layers accumulating on top of it . Upper layers of ice in a core correspond to a single year or sometimes a single season . Deeper into the ice the layers thin and annual layers become indistinguishable . An ice core from the right site can be used to reconstruct an uninterrupted and detailed climate record extending over hundreds of thousands of years , providing information on a wide variety of aspects of climate at each point in time .

Flying birds nest on the milder shores of the Peninsula and the subantarctic islands . Eight species of penguins inhabit Antarctica and its offshore islands . They share these areas with seven pinniped species . The Southern Ocean around Antarctica is home to 10 cetaceans , many of them migratory . There are very few terrestrial invertebrates on the mainland , although the species that do live there have high population densities . High densities of invertebrates also live in the ocean , with Antarctic krill forming dense and widespread swarms during the summer . Benthic animal communities also exist around the continent .

Scientists say halting deforestation ‘just as urgent’ as reducing emissions
[ { "content": "Title: Reducing emissions from deforestation and forest degradation Content: Reducing emissions from deforestation and forest degradation and the role of conservation , sustainable management of forests and enhancement of forest carbon stocks in developing countries ( REDD + ) was first negotiated under the United Nations Framework Convention on Climate Change ( UNFCCC ) since 2005 , with the objective of mitigating climate change through reducing net emissions of greenhouse gases through enhanced forest management in developing countries . Most of the key REDD + decisions were completed by 2013 , with the final pieces of the rulebook finished in 2015 . In the last two decades , various studies estimate that land use change , including deforestation and forest degradation , accounts for 12-29 % of global greenhouse gas emissions . For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) . What remained on forestry was `` Afforestation and Reforestation '' , sectoral scope 14 of the CDM . Under this sectoral scope areas of land that had no forest cover since 1990 could be replanted with commercial or indigenous tree species . In its first eight years of operation 52 projects had been registered under the `` Afforestation and Reforestation '' scope of the CDM . The cumbersome administrative procedures and corresponding high transaction costs are often blamed for this slow uptake . Beyond the CDM , all developed countries that were parties to the Kyoto Protocol also committed to measuring and reporting on efforts to reduce net greenhouse gas emissions from forests . The United States also measures and reports on the net greenhouse gas sequestration in its forests . In response to what many perceived to be a failure to address a major source of global greenhouse gas emissions , the Coalition for Rainforest Nations ( CfRN ) was established and in 2005 they proposed to the Conference of the Parties to the UNFCCC policy approaches and positive incentives for the reduction of emissions of greenhouse gases stemming from tropical deforestation and forest degradation as a climate change mitigation measure .", "qid": "477", "docid": "Reducing_emissions_from_deforestation_and_forest_degradation", "rank": 1, "score": 148041 }, { "content": "Title: United Nations REDD Programme Content: The United Nations Programme on Reducing Emissions from Deforestation and Forest Degradation ( or UN-REDD Programme ) is a collaborative programme of the Food and Agriculture Organization of the United Nations ( FAO ) , the United Nations Development Programme ( UNDP ) and the United Nations Environment Programme ( UNEP ) , created in 2008 in response to the UNFCCC decisions on the Bali Action Plan and REDD at COP-13 .

Examples of deforestation include conversion of forestland to farms , ranches , or urban use . The most concentrated deforestation occurs in tropical rainforests . About 30 % of Earth 's land surface is covered by forests . Deforestation occurs for multiple reasons : trees are cut down to be used for building or sold as fuel , ( sometimes in the form of charcoal or timber ) , while cleared land is used as pasture for livestock and plantation . The removal of trees without sufficient reforestation has resulted in damage to habitat , biodiversity loss and aridity . It has adverse impacts on biosequestration of atmospheric carbon dioxide .

Climate change mitigation generally involves reductions in human ( anthropogenic ) emissions of greenhouse gases ( GHGs ) . Mitigation may also be achieved by increasing the capacity of carbon sinks , e.g. , through reforestation . Mitigation policies can substantially reduce the risks associated with human-induced global warming . According to the IPCC 's 2014 assessment report , `` Mitigation is a public good ; climate change is a case of the ` tragedy of the commons . Effective climate change mitigation will not be achieved if each agent ( individual , institution or country ) acts independently in its own selfish interest ( see international cooperation and emissions trading ) , suggesting the need for collective action . Some adaptation actions , on the other hand , have characteristics of a private good as benefits of actions may accrue more directly to the individuals , regions , or countries that undertake them , at least in the short term . Nevertheless , financing such adaptive activities remains an issue , particularly for poor individuals and countries . '' Examples of mitigation include phasing out fossil fuels by switching to low-carbon energy sources , such as renewable and nuclear energy , and expanding forests and other `` sinks '' to remove greater amounts of carbon dioxide from the atmosphere . Energy efficiency may also play a role , for example , through improving the insulation of buildings . Another approach to climate change mitigation is climate engineering .

The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of GHGs at a level that would prevent dangerous human interference of the climate system .

In the DRC , forests are cleared for agricultural purposes by utilizing slash and burn techniques . Aside from the visible depletion of resources , deforestation of the DRC also leads to a lost habit for the mountain gorilla among other rare species like the okapi , resulting in decreased biodiversity , soil erosion , and contribute to climate change . Since 1990 , the rate of deforestation in the DRC has remained constant at 0.20 % , which equates to the loss of 311,000 hectares , or roughly 1,200 square miles , annually . This amounts to destroying forests the size of Delaware every two years . The fact that the rate of deforestation has remained constant over the last twenty years is misleading as one might believe that government or non-government organizations ( NGO ) interventions have been responsible for the decline , but reports indicate otherwise . Three reasons have been postulated as to why deforestation rates have remained relatively low : 1 ) the road network within the country has been gradually in decline making access to more remote areas more difficult , 2 ) political and regulatory changes have disincentivized investment in the country , and 3 ) agriculture has expanded outside of forest areas . Additionally , while the rates remain constant , wood removal ( measured in cubic meters ) continues to dramatically increase annually . Industrialized roundwood has increased from 3.05 million cubic meters in 1990 to 4.45 million cubic meters in 2010 ; fuelwood has increased from 44.2 million cubic meters to 75.44 million cubic meters annually in that same time .

The law streamlined the permitting process for timber harvests in National Forests by adding new categorical exclusions to the National Forest Service 's list of categorical exclusions from the environmental impact assessment process . Supporters of the law contend that this will reduce wildfire risk by thinning overstocked stands , clearing away vegetation and trees to create shaded fuel breaks , providing funding and guidance to reduce or eliminate hazardous fuels in National Forests , improving forest fire fighting , and researching new methods to halt destructive insects . To proponents , much of the basis for the law revolves around the overcrowding of forests due to the suppression of low intensity fires . The resulting buildup of ground fuels and trees is thought to have increased the size and severity of wildfires in the United States . Detractors of the law contend that the bill opens previously protected forest areas to logging , often unnecessarily or under false pretense .

The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect . This scientific opinion is expressed in synthesis reports , by scientific bodies of national or international standing , and by surveys of opinion among climate scientists . Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys . National and international science academies and scientific societies have assessed current scientific opinion on global warming . These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change . The IPCC Fourth Assessment Report stated that : Warming of the climate system is unequivocal , as evidenced by increases in global average air and ocean temperatures , the widespread melting of snow and ice , and rising global average sea level . Most of the global warming since the mid-20th century is very likely due to human activities . Benefits and costs of climate change for -LSB- human -RSB- society will vary widely by location and scale . Some of the effects in temperate and polar regions will be positive and others elsewhere will be negative . Overall , net effects are more likely to be strongly negative with larger or more rapid warming . The range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time .

Natural scientists warn that immediate action must be taken to lower greenhouse gas emissions and mitigate the effects of climate change .

Thus , governments use GIP to address the economic , political , and environmental issues of climate change . GIP is conducive to sustainable economic , institutional , and technological transformation . It goes beyond the free market economic structure to address market failures and commitment problems that hinder sustainable investment . Effective GIP builds political support for carbon regulation which is necessary to transition towards a low-carbon economy . Several governments use different types of GIP that lead to various outcomes . GIP and industrial policy are similar , although GIP has unique challenges and goals . GIP faces the particular challenge of reconciling economic and environmental issues . It deals with a high uncertainty of green investment profitability . Furthermore , it addresses the reluctance of industry to invest in green development , and it helps current governments influence future climate policy . GIP offers opportunities for energy transition to renewables and a low-carbon economy . A large challenge for climate policy is a lack of industry and public support . GIP creates benefits that attract support for sustainability . It can create strategic niche management and generate a `` green spiral '' , or a process of feedback that combines industrial interests with climate policy . GIP can protect employees in emerging and declining industries , which leads to political support for other climate policy .

Most of the key REDD + decisions were completed by 2013 , with the final pieces of the rulebook finished in 2015 .

For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) .

Air pollution occurs when harmful substances are released into the Earth 's atmosphere . These pollutants are released through human activity and natural sources . Germany took interest in reducing its greenhouse gas ( GHG ) emissions by switching to renewable energy sources . Renewable energy use rose from 6.3 % in 2000 to 34 % in 2016 . Through the transition to renewable energy sources , Germany has become the climate change policy leader and renewable energy leader in the European Union ( EU ) and in the world with ambitious climate change programs . The current goal of the German government was approved on 14 November 2016 in the German Climate Action Plan 2050 , which outlines measures by which Germany can meet its greenhouse gas emissions by 2050 . By 2050 , Germany wants to reduce their GHGs by 80 to 95 % and by 2030 they want to reduce it by 55 % , compared to the EU target of 40 % . In order to achieve these goals , a variety of strategies and policies are used rather than legislation . The four strategies the German government bases air pollution control on are laying down environmental quality standards , emission reduction requirements according to the best available technology , production regulations , and laying down emission ceilings . Through these strategies , policy instruments have been put in place that have contributed to the success of the significant air pollution reduction in Germany . These instruments include the Federal Emission Control Act and Implementing Ordinances , Technical Instructions on Air Quality Control ( TA Luft ) , Amendment to Ordinance on Small Firing Installations , Implementation of the directive on industrial emissions , and Transboundary air pollution control policy . The German Feed-in-Tariff policy introduced in 2000 led to the significant increase in renewable energy use and decreasing air pollution . They have been introduced in Germany to increase the use of renewables , such as wind power , biomass , hydropower , geothermal power , and photovoltaics , thereby reducing GHG emissions causing air pollution and combating climate change . The German government has been an agenda setter in international climate policy negotiations since the late 1980s . However , national and global climate policies have become a top priority since the conservative-social democratic government came into power in 2005 , pushing both European and international climate negotiations . Positive path dependency in Germany 's climate and energy policies has occurred over the past 20 years . There are three main triggers that put Germany on this positive path dependency and what led them to becoming a climate change policy leader . The first being the widespread damages to health , due to smog , and to nature , due to acid rain , caused by air pollution . The second being the shock of the two oil price crises , in 1973 and 1979 , that highlighted the problem of the German economy 's strong dependence on unsure foreign sources . The third being the growing opposition to the country 's growing reliance on nuclear energy . Air pollution began to be seen as a problem in Germany due to these three triggers , causing Germany to put policies into place to control air pollution .

Sustainability of the forest also comes with uncertainties . There are other factors that may affect the forest furthermore than that of the harvesting . There are internal conditions such as effects of soil compaction , tree damage , disease , fire , and blow down that also directly affect the ecosystem . These factors have to be taken into account when determining the sustainability of a forest . If these factors are added to the harvesting and production that comes out of the forest , then the forest will become less likely to survive , and will then become less sustainable . Since the forest is considered an ecosystem , it is dependent on all of the living and non-living factors within itself . This is a major part of why the forest needs to be sustainable before it is harvested . For example , a tree would convert sunlight to sugars for respiration to keep the tree alive . The remains of the converted sugars is left in roots for consumption by the organisms surrounding the tree in the habitat . This shows the productivity of an ecosystem with its inhabitants . Productivity within the ecosystem can not come to fruition unless the forest is sustainable enough to be harvested . If all of the organisms of the ecosystem are non existent , the ecosystem itself will soon come to be non existent . Once that happens , there is no longer any forest to harvest from . The overall productivity of a system can be found in an equation where the Net Primary Production , or NPP , is equal to the Gross Primary Production , or GPP , minus the Respiration , or R . The formula is the NPP = GPP - R . The NPP is the overall efficiency of the plants in the ecosystem . Through having a constant efficiency in NPP , the ecosystem is then more sustainable . The GPP refers to the rate of energy stored by photosynthesis in plants . The R refers to the maintenance and reproduction of plants from the energy expended . Ecoforestry has many principles within the existence of itself . It covers sustainable development and the fair harvesting of the organisms living within the forest ecosystem . There have been many proposals of principles outlined for ecoforestry . They are covered over books , articles , and environmental agencies . All of the principles relate to the idea that in ecoforestry , less should be harvested , and diversity must be managed . Through harvesting less , there is enough biomass left in the forest , so that the forest may stay healthy and still stay maintained . It will grow at a sustainable level annually , and thus it will be able to still be harvested the following year . Through management of the diversity , species may cohabitate in an ecosystem where the forest may feed off of other species in its growth and production .

Every unit of carbon that is absorbed by trees -- or not emitted due to your funding of renewable energy deployment -- offsets the emissions from their fossil fuel use . In many cases , funding of renewable energy , energy efficiency , or tree planting -- particularly in developing nations -- can be a relatively cheap way of making an individual `` carbon neutral '' .

Since the rate was then at 12.4 % , and it had been decades since the state had seen an unemployment rate below 5.5 % for such a period of time , this wording was seen by former Gov. Arnold Schwarzenegger and others as a wording trick to delay the environmental regulations indefinitely . AB 32 requires that greenhouse emission levels in the state be cut to 1990 levels by 2020 , in a gradual process of cutting that is slated to begin in 2012 . Reducing greenhouse emission levels to 1990 levels will involve cutting them by about 15 % from 2010 levels . AB 32 includes a provision allowing the Governor of California to suspend the provisions of AB 32 if there are `` extraordinary circumstances '' in place , such as `` significant economic harm '' . The supporters of Prop 23 , Assemblyman Dan Logue and Ted Costa , decided to circulate a petition to accomplish a suspension of the environmental regulations . Governor Schwarzenegger , as well as the major party candidates for Governor , Jerry Brown , and Meg Whitman , all stated they would vote `` no '' on Prop 23 . Brown however favored `` adjustments '' to AB 32 , while Whitman would have immediately suspended the law . Louise Bedsworth , a research fellow at the Public Policy Institute of California , predicted in April 2010 that total campaign spending on this proposition would top the $ 154 million record set in 2006 by Proposition 87 . If campaign spending on the proposition does reach that level , it could be because supporters and opponents view the battle over the suspension of AB 32 as symbolic in the larger national debate over global warming . Steven Maviglio , speaking for a group that wants to keep AB 32 intact , said , '' ... this could be a ground zero for the battle for the future of clean energy '' .", "qid": "478", "docid": "California_Proposition_23_(2010)", "rank": 54, "score": 105389 }, { "content": "Title: Carbon Pollution Reduction Scheme Content: The Carbon Pollution Reduction Scheme ( or CPRS ) was a cap-and-trade emissions trading scheme for anthropogenic greenhouse gases proposed by the Rudd government , as part of its climate change policy , which had been due to commence in Australia in 2010 . It marked a major change in the energy policy of Australia . The policy began to be formulated in April 2007 , when the federal Labor Party was in Opposition and the six Labor-controlled states commissioned an independent review on energy policy , the Garnaut Climate Change Review , which published a number of reports . After Labor won the 2007 federal election and formed government , it published a Green Paper on climate change for discussion and comment . The Federal Treasury then modelled some of the financial and economic impacts of the proposed CPRS scheme . The Rudd government published a final White Paper on 15 December 2008 , and announced that legislation was intended to take effect in July 2010 ; but the legislation for the CPRS ( aka ETS ) failed to gain the numbers in the Senate and was twice rejected creating a double dissolution election trigger . A bitter political debate within the Coalition Opposition saw Opposition leader Malcolm Turnbull lose the leadership to the anti-CPRS Tony Abbott . The Rudd government did not call an election and in April 2010 , Rudd deferred plans for the CPRS .

By subsector , road transport is the largest contributor to global warming . Environmental regulations in developed countries have reduced the individual vehicle 's emission ; however , this has been offset by an increase in the number of vehicles , and more use of each vehicle . Some pathways to reduce the carbon emissions of road vehicles considerably have been studied . Energy use and emissions vary largely between modes , causing environmentalists to call for a transition from air and road to rail and human-powered transport , and increase transport electrification and energy efficiency . The transportation sector is a major source of greenhouse gas emissions ( GHGs ) in the United States . An estimated 30 percent of national GHGs are directly attributable to transportation -- and in some regions , the proportion is even higher . Transportation methods are the greatest contributing source of GHGs in the U.S. , accounting for 47 percent of the net increase in total U.S. emissions since 1990 .

Climate change mitigation generally involves reductions in human ( anthropogenic ) emissions of greenhouse gases ( GHGs ) . Mitigation may also be achieved by increasing the capacity of carbon sinks , e.g. , through reforestation . Mitigation policies can substantially reduce the risks associated with human-induced global warming . According to the IPCC 's 2014 assessment report , `` Mitigation is a public good ; climate change is a case of the ` tragedy of the commons . Effective climate change mitigation will not be achieved if each agent ( individual , institution or country ) acts independently in its own selfish interest ( see international cooperation and emissions trading ) , suggesting the need for collective action . Some adaptation actions , on the other hand , have characteristics of a private good as benefits of actions may accrue more directly to the individuals , regions , or countries that undertake them , at least in the short term . Nevertheless , financing such adaptive activities remains an issue , particularly for poor individuals and countries . '' Examples of mitigation include phasing out fossil fuels by switching to low-carbon energy sources , such as renewable and nuclear energy , and expanding forests and other `` sinks '' to remove greater amounts of carbon dioxide from the atmosphere . Energy efficiency may also play a role , for example , through improving the insulation of buildings . Another approach to climate change mitigation is climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) . The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of GHGs at a level that would prevent dangerous human interference of the climate system . Scientific analysis can provide information on the impacts of climate change , but deciding which impacts are dangerous requires value judgments . In 2010 , Parties to the UNFCCC agreed that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . With the Paris Agreement of 2015 this was confirmed , but was revised with a new target laying down `` parties will do the best '' to achieve warming below 1.5 ° C .

The ERMS operates under the principles of a cap and trade market system . The ERMS applies only to stationary sources that produce over 10 tons of VOMs during a given compliance period . The compliance period lasts from the beginning of May to the end of September each year as this is the time period in which the air quality tends to be the lowest . The region managed by ERMS , referred to as a nonattainment area for its substandard ozone quality , encompasses the greater metropolitan area of Chicago . In total , the non-attainment area comprises six counties and three townships in the northeast corner of Illinois . Though the ERMS was n't fully operational until May 2000 , the majority of sources were reporting emissions on schedule by 1998 . The ERMS was created by the Illinois Environmental Protection Agency ( IEPA ) in response to the Clean Air Act Amendments of 1990 . Under the amendments , the Chicago metropolitan area was mandated to reduce ozone depleting emissions by 9 % every 3 years from 1996 until the area reached attainment . Wishing to reduce emissions without imposing the economic burdens associated with the traditional command and control approach , The IEPA created this market-based system . The ERMS issues allotment trading units ( ATUs ) which are equivalent to an emission permit worth 200 pounds of VOM . Like most cap and trade programs , any source that exceeds its permitted emissions faces monetary penalties . Unlike similar programs , however , ATUs that go unused in a given season can be held by the emitter for a total of 2 years . The program also contains a failsafe for emitters called the Alternative Compliance Market Account ( ACMA ) . This account exists as a seller of last resort in the event of an emitter being unable to purchase the required amount of ATUs on the open market . It has had minimal use during in the 11 years of ERMS activity . Generally , the ERMS is considered a relatively small trading scheme . In the 2010 season , 234 sources participated in the system while 53 transactions were completed and 8740 ATUs were traded . The results of 11 years of operation by the ERMS are telling . The first seasons of operation saw the average ATU price drop from $ 75.87 to $ 18.75 , or 25 % of their initial value . Since then , the price has fluctuated modestly and ended at $ 20.10 in 2010 . Furthermore , 58 , 834 ATUs expired without use . This accounts for 58.6 % of the total ATUs allotted in 2010 . These figures point to an inherent lack of scarcity in the system . While numerous reasons have been put forth , they generally point to inflated baseline emissions and subsequent over-allotment . Ultimately , even if the ERMS can not be considered an outright success , it provides a wealth of information for those wishing to emulate the plan .

Most of the key REDD + decisions were completed by 2013 , with the final pieces of the rulebook finished in 2015 . In the last two decades , various studies estimate that land use change , including deforestation and forest degradation , accounts for 12-29 % of global greenhouse gas emissions . For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) . What remained on forestry was `` Afforestation and Reforestation '' , sectoral scope 14 of the CDM . Under this sectoral scope areas of land that had no forest cover since 1990 could be replanted with commercial or indigenous tree species . In its first eight years of operation 52 projects had been registered under the `` Afforestation and Reforestation '' scope of the CDM . The cumbersome administrative procedures and corresponding high transaction costs are often blamed for this slow uptake . Beyond the CDM , all developed countries that were parties to the Kyoto Protocol also committed to measuring and reporting on efforts to reduce net greenhouse gas emissions from forests . The United States also measures and reports on the net greenhouse gas sequestration in its forests . In response to what many perceived to be a failure to address a major source of global greenhouse gas emissions , the Coalition for Rainforest Nations ( CfRN ) was established and in 2005 they proposed to the Conference of the Parties to the UNFCCC policy approaches and positive incentives for the reduction of emissions of greenhouse gases stemming from tropical deforestation and forest degradation as a climate change mitigation measure .", "qid": "482", "docid": "Reducing_emissions_from_deforestation_and_forest_degradation", "rank": 1, "score": 105668 }, { "content": "Title: Energy forestry Content: Energy forestry is a form of forestry in which a fast-growing species of tree or woody shrub is grown specifically to provide biomass or biofuel for heating or power generation .

An example of transition toward sustainable energy , is the shift by Germany ( Energiewende ) , to decentralised renewable energy , and energy efficiency . Although so far these shifts have been replacing nuclear energy , their declared goal is the abolishment of coal , reducing non-renewable energy sources and the creation of an energy system based on 60 % renewable energy by 2050 . Renewable energy encompasses wind , hydropower , solar power , geothermal , and ocean power . These renewable sources are to serve as an alternative to fossil fuels ( oil , coal , natural gas ) and nuclear fuel ( uranium ) . Solving the energy/global warming problem is regarded as the most important challenge facing humankind in the 21st century .

Shifting the total global primary energy supply to renewable sources requires a transition of the energy system . In 2013 the Intergovernmental Panel on Climate Change said that there are few fundamental technological limits to integrating a portfolio of renewable energy technologies to meet most of total global energy demand . Renewable energy use has grown much faster than even advocates anticipated . In 2014 , renewable sources such as wind , geothermal , solar , biomass , and burnt waste provided 19 % of the total energy consumed worldwide , with roughly half of that coming from traditional use of biomass . The most important sector is electricity with a renewable share of 22.8 % , most of it coming from hydropower with a share of 16.6 % , followed by wind with 3.1 % . There are many places around the world with grids that are run almost exclusively on renewable energy . At the national level , at least 30 nations already have renewable energy contributing more than 20 % of the energy supply . Professors S. Pacala and Robert H. Socolow of Princeton University have developed a series of `` Climate stabilization wedges '' that can allow us to maintain our quality of life while avoiding catastrophic climate change , and `` renewable energy sources , '' in aggregate , constitute the largest number of their `` wedges . '' Mark Z. Jacobson , professor of civil and environmental engineering at Stanford University and director of its Atmosphere and Energy program , says that producing all new energy with wind power , solar power , and hydropower by 2030 is feasible , and that existing energy supply arrangements could be replaced by 2050 . Barriers to implementing the renewable energy plan are seen to be `` primarily social and political , not technological or economic '' . Jacobson says that energy costs today with a wind , solar , and water system should be similar to today 's energy costs from other optimally cost-effective strategies . The main obstacle against this scenario is the lack of political will . Similarly , in the United States , the independent National Research Council has noted that `` sufficient domestic renewable resources exist to allow renewable electricity to play a significant role in future electricity generation and thus help confront issues related to climate change , energy security , and the escalation of energy costs ... Renewable energy is an attractive option because renewable resources available in the United States , taken collectively , can supply significantly greater amounts of electricity than the total current or projected domestic demand . '' The main barriers to the widespread implementation of large-scale renewable energy and low-carbon energy strategies are political rather than technological . According to the 2013 Post Carbon Pathways report , which reviewed many international studies , the key roadblocks are : climate change denial , the fossil fuels lobby , political inaction , unsustainable energy consumption , outdated energy infrastructure , and financial constraints .", "qid": "482", "docid": "100%_renewable_energy", "rank": 31, "score": 81157 }, { "content": "Title: Wood economy Content: The existence of a wood economy , or more broadly , a forest economy ( since in many countries a bamboo economy predominates ) , is a prominent matter in many developing countries as well as in many other nations with temperate climate and especially in those with low temperatures .

Trees : Protecting forests and planting new trees contributes to the absorption of carbon dioxide from the air . There are many opportunities to plant trees in the yard , along roads , in parks , and in public gardens . In addition , some charities plant fast-growing trees -- for as little as $ US0 .10 per tree -- to help people in tropical developing countries restore the productivity of their lands .

Every unit of carbon that is absorbed by trees -- or not emitted due to your funding of renewable energy deployment -- offsets the emissions from their fossil fuel use . In many cases , funding of renewable energy , energy efficiency , or tree planting -- particularly in developing nations -- can be a relatively cheap way of making an individual `` carbon neutral '' .

The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect . This scientific opinion is expressed in synthesis reports , by scientific bodies of national or international standing , and by surveys of opinion among climate scientists . Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys . National and international science academies and scientific societies have assessed current scientific opinion on global warming . These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change . The IPCC Fourth Assessment Report stated that : Warming of the climate system is unequivocal , as evidenced by increases in global average air and ocean temperatures , the widespread melting of snow and ice , and rising global average sea level . Most of the global warming since the mid-20th century is very likely due to human activities . Benefits and costs of climate change for -LSB- human -RSB- society will vary widely by location and scale . Some of the effects in temperate and polar regions will be positive and others elsewhere will be negative . Overall , net effects are more likely to be strongly negative with larger or more rapid warming . The range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time .

The main idea of Ecoforestry is to maintain or restore the forest to standards where the forest may still be harvested for products on a sustainable basis . Ecoforestry is forestry that emphasizes holistic practices which strive to protect and restore ecosystems rather than maximize economic productivity . Sustainability of the forest also comes with uncertainties . There are other factors that may affect the forest furthermore than that of the harvesting . There are internal conditions such as effects of soil compaction , tree damage , disease , fire , and blow down that also directly affect the ecosystem . These factors have to be taken into account when determining the sustainability of a forest . If these factors are added to the harvesting and production that comes out of the forest , then the forest will become less likely to survive , and will then become less sustainable . Since the forest is considered an ecosystem , it is dependent on all of the living and non-living factors within itself . This is a major part of why the forest needs to be sustainable before it is harvested . For example , a tree would convert sunlight to sugars for respiration to keep the tree alive . The remains of the converted sugars is left in roots for consumption by the organisms surrounding the tree in the habitat . This shows the productivity of an ecosystem with its inhabitants . Productivity within the ecosystem can not come to fruition unless the forest is sustainable enough to be harvested . If all of the organisms of the ecosystem are non existent , the ecosystem itself will soon come to be non existent . Once that happens , there is no longer any forest to harvest from . The overall productivity of a system can be found in an equation where the Net Primary Production , or NPP , is equal to the Gross Primary Production , or GPP , minus the Respiration , or R . The formula is the NPP = GPP - R . The NPP is the overall efficiency of the plants in the ecosystem . Through having a constant efficiency in NPP , the ecosystem is then more sustainable . The GPP refers to the rate of energy stored by photosynthesis in plants . The R refers to the maintenance and reproduction of plants from the energy expended . Ecoforestry has many principles within the existence of itself . It covers sustainable development and the fair harvesting of the organisms living within the forest ecosystem . There have been many proposals of principles outlined for ecoforestry . They are covered over books , articles , and environmental agencies . All of the principles relate to the idea that in ecoforestry , less should be harvested , and diversity must be managed . Through harvesting less , there is enough biomass left in the forest , so that the forest may stay healthy and still stay maintained . It will grow at a sustainable level annually , and thus it will be able to still be harvested the following year . Through management of the diversity , species may cohabitate in an ecosystem where the forest may feed off of other species in its growth and production .

The term `` landscape turnaround '' has also been used to represent a more general recovery of natural areas that is independent of biome type . Forest recovery resulting in net increases in forest extent can occur by means of spontaneous regeneration , active planting , or both . Forest transitions are associated with socio-economic transformations towards increased industrialization and urbanization . Other conditions leading to the abandonment of agricultural land ( e.g. , war and environmental legislation ) have been found to play important roles in some cases . The different processes through which forest transitions occur are contingent upon the local socioeconomic and ecological contexts . Although some generic processes can be identified , countries do not necessarily experience a regular pattern of forest cover changes with time or development , and the causes and outcomes of forest transitions vary . Studies of forest transitions have been conducted for several nations as well as sub-national regions . Territories reported to have experienced forest transitions after the onset of industrialization include Bangladesh , China , Costa Rica , Cuba , Denmark , Canada , Dominican Republic , El Salvador , France , Greece , Gambia , Hungary , Ireland , Italy , Japan , Morocco , Norway , New Zealand , Portugal , Puerto Rico , Rwanda , Scotland , South Korea , Spain , Switzerland , the United States , the United Kingdom , and Vietnam . Furthermore , forest-transition dynamics have been documented for regions within Brazil , Ecuador , and Mexico . The environmental effects of these forest transitions are very variable , depending on whether deforestation of old-growth forests continue , the proportions and types of tree plantations versus natural regeneration of forests , and the location and spatial configuration of the different types of forests . The findings of returning forests in these widespread studies raise questions about the prospects of a worldwide forest transition , particularly given ongoing processes of forest loss in many parts of the world . In other words , can the global extent of forests be expected to reach a turning point in the future , reversing the current trend of overall forest decline towards overall forest expansion ? Studies showed that given an increased competition for productive land between different land uses , a global forest transition would require major policy and technological innovations as well as shifts in demands for fiber , fuel , and food , and that these changes can not be taken for granted .", "qid": "482", "docid": "Forest_transition", "rank": 72, "score": 75256 }, { "content": "Title: International Year of Forests Content: The year 2011 was declared the International Year of Forests by the United Nations to raise awareness and strengthen the sustainable management , conservation and sustainable development of all types of forests for the benefit of current and future generations .", "qid": "482", "docid": "International_Year_of_Forests", "rank": 73, "score": 75159 }, { "content": "Title: Brazilian Forest Code Content: The Brazilian Forest Code is a piece of legislation passed in 1965 .

The law streamlined the permitting process for timber harvests in National Forests by adding new categorical exclusions to the National Forest Service 's list of categorical exclusions from the environmental impact assessment process .

The carrying capacity of an ecosystem is reduced over time if more than the amount which is `` renewed '' ( refreshed or regrown or rebuilt ) is consumed . Ecosystem services analysis calculates the global yield of the Earth 's biosphere to humans as a whole . This is said to be greater in size than the entire human economy . However , it is more than just yield , but also the natural processes that increase biodiversity and conserve habitat which result in the total value of these services . `` Yield '' of ecological commodities like wood or water , useful to humans , is only a part of it . Very often an ecological yield in one place offsets an ecological load in another . Greenhouse gas released in one place , for instance , is fairly evenly distributed in the atmosphere , and so greenhouse gas control can be achieved by creating a carbon sink literally anywhere else .

Most of the key REDD + decisions were completed by 2013 , with the final pieces of the rulebook finished in 2015 .

For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) .

Examples of deforestation include conversion of forestland to farms , ranches , or urban use . The most concentrated deforestation occurs in tropical rainforests . About 30 % of Earth 's land surface is covered by forests . Deforestation occurs for multiple reasons : trees are cut down to be used for building or sold as fuel , ( sometimes in the form of charcoal or timber ) , while cleared land is used as pasture for livestock and plantation . The removal of trees without sufficient reforestation has resulted in damage to habitat , biodiversity loss and aridity . It has adverse impacts on biosequestration of atmospheric carbon dioxide .

The fact that the rate of deforestation has remained constant over the last twenty years is misleading as one might believe that government or non-government organizations ( NGO ) interventions have been responsible for the decline , but reports indicate otherwise .

Climate change mitigation generally involves reductions in human ( anthropogenic ) emissions of greenhouse gases ( GHGs ) . Mitigation may also be achieved by increasing the capacity of carbon sinks , e.g. , through reforestation . Mitigation policies can substantially reduce the risks associated with human-induced global warming . According to the IPCC 's 2014 assessment report , `` Mitigation is a public good ; climate change is a case of the ` tragedy of the commons . Effective climate change mitigation will not be achieved if each agent ( individual , institution or country ) acts independently in its own selfish interest ( see international cooperation and emissions trading ) , suggesting the need for collective action . Some adaptation actions , on the other hand , have characteristics of a private good as benefits of actions may accrue more directly to the individuals , regions , or countries that undertake them , at least in the short term . Nevertheless , financing such adaptive activities remains an issue , particularly for poor individuals and countries . '' Examples of mitigation include phasing out fossil fuels by switching to low-carbon energy sources , such as renewable and nuclear energy , and expanding forests and other `` sinks '' to remove greater amounts of carbon dioxide from the atmosphere . Energy efficiency may also play a role , for example , through improving the insulation of buildings . Another approach to climate change mitigation is climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) . The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of GHGs at a level that would prevent dangerous human interference of the climate system . Scientific analysis can provide information on the impacts of climate change , but deciding which impacts are dangerous requires value judgments . In 2010 , Parties to the UNFCCC agreed that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . With the Paris Agreement of 2015 this was confirmed , but was revised with a new target laying down `` parties will do the best '' to achieve warming below 1.5 ° C .

Much of the carbon in the peat deposits produced by coal forests came from photosynthetic splitting of existing carbon dioxide , which released the accompanying split-off oxygen into the atmosphere . This process may have greatly increased the oxygen level , possibly as high as about 35 % , making the air more easily breathable by animals with inefficient respiratory systems , as indicated by the size of Meganeura compared to modern dragonflies . Coal forests covered tropical Euramerica ( Europe , eastern North America , northwesternmost Africa ) and Cathaysia ( mainly China ) . Climate change devastated these tropical rainforests during the Carboniferous period . The Carboniferous Rainforest Collapse was caused by a cooler drier climate that initially fragmented , then collapsed the rainforest ecosystem . During most of the rest of Carboniferous times , the coal forests were mainly restricted to refugia in North America ( such as the Appalachian and Illinois coal basins ) and central Europe . At the very end of the Carboniferous period , the coal forests underwent a resurgence , expanding mainly in eastern Asia , notably China ; they never recovered fully in Euramerica . The Chinese coal forests continued to flourish well into Permian times . This resurgence of the coal forests in very late Carboniferous times seems to have coincided with a lowering of global temperatures and a return of extensive polar ice in southern Gondwana , perhaps due to lessening of the greenhouse effect as the massive coal deposition process abstracted carbon dioxide from the atmosphere .", "qid": "484", "docid": "Coal_forest", "rank": 42, "score": 97856 }, { "content": "Title: Bonn Challenge Content: The Bonn Challenge is a global effort to restore 150 million hectares of the world 's degraded and deforested lands by 2020 .

The term `` landscape turnaround '' has also been used to represent a more general recovery of natural areas that is independent of biome type .

Forest transitions are associated with socio-economic transformations towards increased industrialization and urbanization . Other conditions leading to the abandonment of agricultural land ( e.g. , war and environmental legislation ) have been found to play important roles in some cases . The different processes through which forest transitions occur are contingent upon the local socioeconomic and ecological contexts .

The main idea of Ecoforestry is to maintain or restore the forest to standards where the forest may still be harvested for products on a sustainable basis . Ecoforestry is forestry that emphasizes holistic practices which strive to protect and restore ecosystems rather than maximize economic productivity . Sustainability of the forest also comes with uncertainties . There are other factors that may affect the forest furthermore than that of the harvesting . There are internal conditions such as effects of soil compaction , tree damage , disease , fire , and blow down that also directly affect the ecosystem . These factors have to be taken into account when determining the sustainability of a forest . If these factors are added to the harvesting and production that comes out of the forest , then the forest will become less likely to survive , and will then become less sustainable . Since the forest is considered an ecosystem , it is dependent on all of the living and non-living factors within itself . This is a major part of why the forest needs to be sustainable before it is harvested . For example , a tree would convert sunlight to sugars for respiration to keep the tree alive . The remains of the converted sugars is left in roots for consumption by the organisms surrounding the tree in the habitat . This shows the productivity of an ecosystem with its inhabitants . Productivity within the ecosystem can not come to fruition unless the forest is sustainable enough to be harvested . If all of the organisms of the ecosystem are non existent , the ecosystem itself will soon come to be non existent . Once that happens , there is no longer any forest to harvest from . The overall productivity of a system can be found in an equation where the Net Primary Production , or NPP , is equal to the Gross Primary Production , or GPP , minus the Respiration , or R . The formula is the NPP = GPP - R . The NPP is the overall efficiency of the plants in the ecosystem . Through having a constant efficiency in NPP , the ecosystem is then more sustainable . The GPP refers to the rate of energy stored by photosynthesis in plants . The R refers to the maintenance and reproduction of plants from the energy expended . Ecoforestry has many principles within the existence of itself . It covers sustainable development and the fair harvesting of the organisms living within the forest ecosystem . There have been many proposals of principles outlined for ecoforestry . They are covered over books , articles , and environmental agencies . All of the principles relate to the idea that in ecoforestry , less should be harvested , and diversity must be managed . Through harvesting less , there is enough biomass left in the forest , so that the forest may stay healthy and still stay maintained . It will grow at a sustainable level annually , and thus it will be able to still be harvested the following year . Through management of the diversity , species may cohabitate in an ecosystem where the forest may feed off of other species in its growth and production .

In 1990 , Kentucky emitted 35.4 million metric tons of carbon equivalent ( MMTCE ) . In addition , Kentucky estimated emissions of 0.4 MMTCE from biofuels . Emissions from biofuels are not included . The principal greenhouse gases were carbon dioxide , comprising 87.9 million metric tons ( 24.0 MMTCE ) , and methane , with 1.1 million metric tons ( 6.4 MMTCE ) . Other emissions included 0.0016 million metric tons of perfluorocarbons ( PFCs ) ( 4.8 MMTCE ) , and 0.003 million metric tons of nitrous oxide ( 0.2 MMTCE ) The major source of carbon dioxide emissions was fossil fuel combustion ( 96 % ) , the majority of which is utility coal . Minor emissions came from cement and lime production and forest/grassland conversion . Carbon dioxide sinks ( i.e. , an increase in forest carbon storage ) offset about 26 % of the total carbon dioxide emissions . Sources of methane emissions were coal mining ( 73 % ) , domesticated animals ( 12 % ) , landfills ( 10 % ) , manure management ( 3 % ) , and natural gas/oil extraction ( 2 % ) . Nitrous oxide emissions were from fertilizer use . Sources of perfluorocarbons were HCFC-22 production ( 91 % ) and aluminum production ( 9 % ) . Kentucky 's emissions in 1990 were 9.6 MTCE per capita , compared to 1990 U.S. emissions of 6.4 MTCE per capita .

This is a derivative of Karl Marx 's concept of metabolic rift . In practical terms , increased commodity production demands that greater levels of carbon dioxide ( or CO2 ) be emitted into the biosphere via fossil fuel consumption . Carbon rift theory states that this ultimately disrupts the natural carbon cycle and that this `` rift '' has adverse effects on nearly every aspect of life . Many of the specifics regarding how this metabolic carbon rift interacts with capitalism are proposed by Brett Clark and Richard York in a 2005 article titled `` Carbon Metabolism : Global capitalism , climate change , and the biospheric rift '' in the journal Theory and Society . Researchers such as Jean P. Sapinski of the University of Oregon claim that , despite increased interest in closing the carbon rift , it is projected that as long as capitalism continues , there is little hope of reducing the rift . Both deforestation and the emission of greenhouse gases have been linked to increased atmospheric CO2 levels . Carbon rift theory states that these are the result of human production through capitalistic systems . There are proposed solutions to climate change such as geoengineering proposed in the December 2015 Paris Agreement . However , some argue that the capitalist mode of production is at fault for the emission of greenhouse gas and that solutions must be found to this issue before climate change itself can be addressed . Carbon rift theory , while rarely criticized directly , often indirectly receives criticism regarding the underlying causes of climate change and attributing the stated effects to alternative explanations for climate change , instead of as a result of human activity .

Monitoring carbon emissions is key to the cap-and-trade program currently being used in Europe , as well as the one in California , and will be necessary for any such program in the future , like the Paris Agreement .

India is one of the ten most forest-rich countries of the world along with the Russian Federation , Brazil , Canada , United States of America , China , Democratic Republic of the Congo , Australia , Indonesia and Sudan . Together , India and these countries account for 67 percent of total forest area of the world . India 's forest cover grew at 0.22 % annually over 1990-2000 , and has grown at the rate of 0.46 % per year over 2000-2010 , after decades where forest degradation was a matter of serious concern . As of 2010 , the Food and Agriculture Organisation of the United Nations estimates India 's forest cover to be about 68 million hectares , or 22 % of the country 's area . The 2013 Forest Survey of India states its forest cover increased to 69.8 million hectares by 2012 , per satellite measurements ; this represents an increase of 5,871 square kilometers of forest cover in 2 years . However , the gains were primarily in northern , central and southern Indian states , while northeastern states witnessed a net loss in forest cover over 2010 to 2012 . In 2002 , forestry industry contributed 1.7 % to India 's GDP . In 2010 , the contribution to GDP dropped to 0.9 % , largely because of rapid growth of the economy in other sectors and the government 's decision to reform and reduce import tariffs to let imports satisfy the growing Indian demand for wood products . India produces a range of processed forest ( wood and non-wood ) products ranging from wood panel products and wood pulp to make bronze , rattazikistan ware and pern resin . India 's paper industry produces over 3,000 metric tonnes annually from more than 400 mills . The furniture and craft industry is another consumer of wood . India 's wood-based processing industries consumed about 30 million cubic metres of industrial wood in 2002 . India annually consumes an additional 270 million tonnes of fuelwood , 2800 million tonnes of fodder , and about 102 million cubic meter of forest products - valued at about a year . India is one of the world 's largest consumer of fuel-wood . India 's consumption of fuel-wood is about five times higher than what can be sustainably removed from forests . However , a large percentage of this fuel-wood is grown as biomass remaining from agriculture , and is managed outside forests . Fuel-wood meets about 40 % of the energy needs of the country . Around 80 % of rural people and 48 % of urban people use fuel-wood . Unless India makes major , rapid and sustained effort to expand electricity generation and power plants , the rural and urban poor in India will continue to meet their energy needs through unsustainable destruction of forests and fuel wood consumption . India 's dependence on fuel-wood and forestry products as a primary energy source is not only environmentally unsustainable , it is a primary cause of India 's near-permanent haze and air pollution . Forestry in India is more than just about wood and fuel . India has a thriving non-wood forest products industry , which produces latex , gums , resins , essential oils , flavours , fragrances and aroma chemicals , incense sticks , handicrafts , thatching materials and medicinal plants . About 60 % of non-wood forest products production is consumed locally . About 50 % of the total revenue from the forestry industry in India is in non-wood forest products category .

Loss and damage can result from sudden-onset events ( climate disasters , such as cyclones ) as well as slow-onset processes ( such as sea level rise ) . Loss and damage can occur in human systems ( such as livelihoods ) as well as natural systems ( such as biodiversity ) , though the emphasis in research and policy is on human impacts . Within the realm of loss and damage to human systems , a distinction is made between economic losses and non-economic losses . The main difference between the two is that non-economic losses involve things that are not commonly traded in markets . At the 18th Conference of the Parties meeting of the UNFCCC in 2012 in Doha , Qatar , it took 36 hours of negotiation between 195 nations to arrive at a plan to address loss and damage associated with adverse effects of climate change particularly in countries most vulnerable to climate change . A new website was launched at the conference by the Loss and Damage Vulnerable Countries Initiative . It described its aim as being `` the first dedicated site for news , resources and opinion on the issue of loss and damage associated with the adverse impacts of climate change '' . Examples of types of loss and damage include farmers who can no longer grow crops to eat , or grass to feed cattle , because their soil has become too salty , and fishermen who have lost their livelihoods because rivers have dried up . In popular press , and in statements by some parties in the climate negotiations , the terms loss and damage is often associated with liability and compensation . This explains why the topic raises heated debates , and tends to widen the divide between developed countries , which are historically responsible for most greenhouse gas emissions , and developing countries that are more vulnerable to impacts of climate change . For vulnerable countries , loss and damage is most of all about recognizing that past and current efforts to avoid dangerous climate change , and that there are limits and constraints to adaptation . The United Nations Framework Convention on Climate Change has developed a work programme on loss and damage which aims to find ways to address the issue in developing countries that are particularly vulnerable to the adverse effects of climate change . On 12 -- 14 September 2013 , it held a meeting in Fiji to consider how best to address loss and damage from ` slow-onset events ' . These are impacts of climate change that occur over time , such as sea-level rise , rather than in a single , destructive event . Bangladesh is already suffering from loss and damage resulting from sea-level rise , due to its flat terrain in the coastal region . At the 19th Conference of the Parties meeting of the UNFCCC in 2013 in Warsaw , Poland , the Warsaw International Mechanism for Loss and Damage associated with Climate Change Impacts was established .

A qualitative data analysis ( QDA ) of what the IPCC 5th Assessment Report has to say about loss and damage surprisingly showed that the term was used much more often in statements about Annex 1 countries ( e.g. US , Australia or European countries ) than in text about non-Annex 1 countries ( most countries in Africa , Asia Latin America and the Pacific ) , which tend to be more vulnerable to impacts of climate change .

For instance as oceans are warming and becoming more acidic, biodiversity is becoming reduced and changing currents will cause more frequent storms and droughts. Every year around 8 million metric tons of plastic waste leak into the ocean and make it into the circular ocean currents. This causes contamination of sediments at the sea-bottom and causes plastic waste to be embedded in the aquatic food chain. It could lead to oceans containing more plastics than fish by 2050 if nothing is done. Key habitats such as coral reefs are at risk and noise pollution are a threat to whales, dolphins, and other species. Furthermore almost 90 percent of fish stocks are overfished or fully exploited which cost more than $80 billion a year in lost revenues.UN Secretary-General António Guterres stated that decisive, coordinated global action can solve the problems created by Humanity.

Disruption due to climate change , or other anthropogenic perturbations can result in decreased productivity and in some cases lead to disruptions in global biogeochemical cycles . The possible ramifications of changes in ecosystem biodiversity are not well characterized or understood , and it may be possible that disruption , up to a point , will have little to no effect given the redundancy within an ecosystem . This is particularly troubling in the context of microbial ecosystems . The dynamics of microbial ecosystems are tightly coupled to biogeochemical processes , and any perturbation within this system in particular could result in dramatic changes ( Kirchman , 2008 ) . For example , the microbial loop within the marine context is responsible for the decomposition of organics and recycling of nutrients back into the ecosystem . This allows for other organisms , such as phytoplankton , to reuse essential nutrients , like nitrogen , and continue production ( Kirchman 2008 ) . Without this recycled nitrogen , phytoplankton would be highly limited in their production rates , in turn limiting the growth of grazers . The effects of such an occurrence would reverberate throughout the food web , and nitrogen cycle . It is important to establish a base line of microbial diversity within ecosystems in order to gauge possible change due to climate change and the possible outcomes . Recent use of high-throughput sequencing techniques has broadened the scope of biodiversity , with the discovery of what has been titled the `` Rare Biosphere '' ( Sogin et al. , 2006 ) . Previous attempts to characterize in situ abundance have been made through pure culture and molecular techniques ( Fuhrman , 2009 ) . Pure culture providing a very narrow picture of some of the rarer species present , < 1-5 % of bacteria present ( Fuhrman , 2009 ) . Molecular techniques , such as Sanger sequencing , resulting in a much broader scope but highlighting the more abundant species present ( Heidelberg et al. , 2010 ) ( Pedros-Alio , 2007 ) . Neither technique captures all of the diversity present . Alternatively high throughput sequencing , `` tag sequencing '' , divides unique rRNA tag sequences into operational taxonomic units ( OTUs ) based upon similarities in mitochondrial-encoded cytochrome oxidases ( Sogin et al. , 2006 ) . Both Sanger , shot gun sequencing , and tag sequencing organize sequences into OTUs ( Heidelberg et al. , 2010 ) . However , it is the resolution that tag sequencing provides that sets it apart , resulting from the increased efficiency in serial analysis ( Heidelberg et al. , 2010 ) . This efficiency increase is made possible through the use of internal primer sequences resulting in restriction-digest overhanging sequences ( Heidelberg et al. , 2010 ) . Though OTUs provide a means of distinguishing the possible number of phylogenetic groups , it is not possible to deduce phylogenetic relationships based upon OTU 's . Tags associated with OTUs must be cross-referenced with gene banks , in order for tags to be phylotyped and relationships established ( Sogin et al. , 2006 ) . The result of tag sequencing has been to produce orders of magnitude larger estimates of OTUs present in ecosystems , producing a long tail on species abundance curves ( Patterson , 2009 ) ( Pedrós-Alío , 2007 ) . This long tail accounts for less than .1 % of the abundant species in a particular ecosystem . At the same time it represents thousands of populations accounting for most of the phylogenetic diversity in an ecosystem . This low-abundance high-diversity group is what is now called the `` Rare Biosphere '' . Using this method , Sogin et al. 's study of microbial diversity in North Atlantic deep water produced an estimate of 5266 different taxa ( Sogin et al. , 2006 ) . This is particularly dramatic considering that previous studies employing more traditional PCR cloning techniques have resulted in estimates of up to 500 ( Pedrós-Alío , 2007 ) .", "qid": "487", "docid": "Rare_biosphere", "rank": 8, "score": 95779 }, { "content": "Title: Effects of climate change on terrestrial animals Content: Climate change has had a significant direct effect on terrestrial animals , by being a major driver of the processes of speciation and extinction . The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction . Climate changes is projected to affect individual organisms , populations , species distributions and ecosystem composition and function both directly ( ex . Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) . Every organism has a unique set of preferences or requirements , a niche and biodiversity has been tied to the diversity of animals ' niches . These can include or be affected by temperature , aridity , resource availability , habitat requirements , enemies , soil characteristics , competitors , and pollinators . Since the factors that compose a niche can be so complex and interconnected , the niches of many animals are bound to be affected by climate change ( Parmesan Yohe 2003 ) .

In the DRC , forests are cleared for agricultural purposes by utilizing slash and burn techniques . Aside from the visible depletion of resources , deforestation of the DRC also leads to a lost habit for the mountain gorilla among other rare species like the okapi , resulting in decreased biodiversity , soil erosion , and contribute to climate change . Since 1990 , the rate of deforestation in the DRC has remained constant at 0.20 % , which equates to the loss of 311,000 hectares , or roughly 1,200 square miles , annually . This amounts to destroying forests the size of Delaware every two years . The fact that the rate of deforestation has remained constant over the last twenty years is misleading as one might believe that government or non-government organizations ( NGO ) interventions have been responsible for the decline , but reports indicate otherwise . Three reasons have been postulated as to why deforestation rates have remained relatively low : 1 ) the road network within the country has been gradually in decline making access to more remote areas more difficult , 2 ) political and regulatory changes have disincentivized investment in the country , and 3 ) agriculture has expanded outside of forest areas . Additionally , while the rates remain constant , wood removal ( measured in cubic meters ) continues to dramatically increase annually .

The large number of extinctions spans numerous families of plants and animals , including mammals , birds , amphibians , reptiles and arthropods . With widespread degradation of highly biodiverse habitats such as coral reefs and rainforest , as well as other areas , the vast majority of these extinctions is thought to be undocumented . According to the species-area theory , and based on upper-bound estimating , the present rate of extinction may be up to 140,000 species per year , making it the greatest loss of biodiversity since the Cretaceous -- Paleogene extinction event . The Holocene extinction includes the disappearance of large land animals known as megafauna , starting at the end of the last Ice Age . Megafauna outside of the African continent , which did not evolve alongside humans , proved highly sensitive to the introduction of new predation , and many died out shortly after early humans began spreading and hunting across the Earth ( additionally , many African species have also gone extinct in the Holocene ) . These extinctions , occurring near the Pleistocene -- Holocene boundary , are sometimes referred to as the Quaternary extinction event . The arrival of humans on different continents coincides with megafaunal extinction . The most popular theory is that human overhunting of species added to existing stress conditions . Although there is debate regarding how much human predation affected their decline , certain population declines have been directly correlated with human activity , such as the extinction events of New Zealand and Hawaii . Aside from humans , climate change may have been a driving factor in the megafaunal extinctions , especially at the end of the Quaternary . The ecology of humanity has been noted as being that of an unprecedented `` global superpredator '' that regularly preys on the adults of other apex predators and has worldwide effects on food webs . Extinctions of species have occurred on every land mass and ocean , with many famous examples within Africa , Asia , Europe , Australia , North and South America , and on smaller islands .

According to the United Nations Environment Programme , biodiversity typically measures variation at the genetic , the species , and the ecosystem level . Terrestrial biodiversity tends to be greater near the equator , which seems to be the result of the warm climate and high primary productivity . Biodiversity is not distributed evenly on Earth , and is richest in the tropics . These tropical forest ecosystems cover less than 10 per cent of earth 's surface , and contain about 90 percent of the world 's species . Marine biodiversity tends to be highest along coasts in the Western Pacific , where sea surface temperature is highest and in the mid-latitudinal band in all oceans . There are latitudinal gradients in species diversity . Biodiversity generally tends to cluster in hotspots , and has been increasing through time , but will be likely to slow in the future . Rapid environmental changes typically cause mass extinctions . More than 99.9 percent of all species , amounting to over five billion species , that ever lived on Earth are estimated to be extinct . Estimates on the number of Earth 's current species range from 10 million to 14 million , of which about 1.2 million have been documented and over 86 percent have not yet been described . More recently , in May 2016 , scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described . The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes . In comparison , the total mass of the biosphere has been estimated to be as much as 4 TtC ( trillion tons of carbon ) . In July 2016 , scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor ( LUCA ) of all organisms living on Earth . The age of the Earth is about 4.54 billion years old . The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago , during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon . There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia . Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland . More recently , in 2015 , `` remains of biotic life '' were found in 4.1 billion-year-old rocks in Western Australia . According to one of the researchers , `` If life arose relatively quickly on Earth . . then it could be common in the universe . '' Since life began on Earth , five major mass extinctions and several minor events have led to large and sudden drops in biodiversity . The Phanerozoic eon ( the last 540 million years ) marked a rapid growth in biodiversity via the Cambrian explosion -- a period during which the majority of multicellular phyla first appeared . The next 400 million years included repeated , massive biodiversity losses classified as mass extinction events . In the Carboniferous , rainforest collapse led to a great loss of plant and animal life . The Permian -- Triassic extinction event , 251 million years ago , was the worst ; vertebrate recovery took 30 million years . The most recent , the Cretaceous -- Paleogene extinction event , occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the dinosaurs . The period since the emergence of humans has displayed an ongoing biodiversity reduction and an accompanying loss of genetic diversity . Named the Holocene extinction , the reduction is caused primarily by human impacts , particularly habitat destruction .

Even if emissions are stabilized relatively soon , global warming and its effects will last many years , and adaptation will be necessary to the resulting changes in climate . Adaptation is especially important in developing countries since those countries are predicted to bear the brunt of the effects of global warming . That is , the capacity and potential for humans to adapt ( called adaptive capacity ) is unevenly distributed across different regions and populations , and developing countries generally have less capacity to adapt ( Schneider et al. , 2007 ) . Furthermore , the degree of adaptation correlates to the situational focus on environmental issues . Therefore , adaptation requires the situational assessment of sensitivity and vulnerability to environmental impacts . Adaptive capacity is closely linked to social and economic development ( IPCC , 2007 ) . The economic costs of adaptation to climate change are likely to cost billions of dollars annually for the next several decades , though the amount of money needed is unknown . Donor countries promised an annual $ 100 billion by 2020 through the Green Climate Fund for developing countries to adapt to climate change . However , while the fund was set up during COP16 in Cancún , concrete pledges by developed countries have not been forthcoming . The adaptation challenge grows with the magnitude and the rate of climate change . Another response to climate change , known as climate change mitigation ( Verbruggen , 2007 ) is to reduce greenhouse gas ( GHG ) emissions and/or enhance the removal of these gases from the atmosphere ( through carbon sinks ) . Even the most effective reductions in emissions , however , would not prevent further climate change impacts , making the need for adaptation unavoidable ( Klein et al. , 2007 ) . In a literature assessment , Klein et al. ( 2007 ) assessed options for adaptation . They concluded , with very high confidence , that in the absence of mitigation efforts , the effects of climate change would reach such a magnitude as to make adaptation impossible for some natural ecosystems . Others are concerned that climate adaptation programs might interfere with the existing development programs and thus lead to unintended consequences for vulnerable groups .

Climate change mitigation generally involves reductions in human ( anthropogenic ) emissions of greenhouse gases ( GHGs ) . Mitigation may also be achieved by increasing the capacity of carbon sinks , e.g. , through reforestation . Mitigation policies can substantially reduce the risks associated with human-induced global warming . According to the IPCC 's 2014 assessment report , `` Mitigation is a public good ; climate change is a case of the ` tragedy of the commons . Effective climate change mitigation will not be achieved if each agent ( individual , institution or country ) acts independently in its own selfish interest ( see international cooperation and emissions trading ) , suggesting the need for collective action . Some adaptation actions , on the other hand , have characteristics of a private good as benefits of actions may accrue more directly to the individuals , regions , or countries that undertake them , at least in the short term . Nevertheless , financing such adaptive activities remains an issue , particularly for poor individuals and countries . '' Examples of mitigation include phasing out fossil fuels by switching to low-carbon energy sources , such as renewable and nuclear energy , and expanding forests and other `` sinks '' to remove greater amounts of carbon dioxide from the atmosphere . Energy efficiency may also play a role , for example , through improving the insulation of buildings . Another approach to climate change mitigation is climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) . The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of GHGs at a level that would prevent dangerous human interference of the climate system . Scientific analysis can provide information on the impacts of climate change , but deciding which impacts are dangerous requires value judgments . In 2010 , Parties to the UNFCCC agreed that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . With the Paris Agreement of 2015 this was confirmed , but was revised with a new target laying down `` parties will do the best '' to achieve warming below 1.5 ° C . The current trajectory of global greenhouse gas emissions does not appear to be consistent with limiting global warming to below 1.5 or 2 ° C .

Most of the key REDD + decisions were completed by 2013 , with the final pieces of the rulebook finished in 2015 . In the last two decades , various studies estimate that land use change , including deforestation and forest degradation , accounts for 12-29 % of global greenhouse gas emissions . For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) . What remained on forestry was `` Afforestation and Reforestation '' , sectoral scope 14 of the CDM . Under this sectoral scope areas of land that had no forest cover since 1990 could be replanted with commercial or indigenous tree species . In its first eight years of operation 52 projects had been registered under the `` Afforestation and Reforestation '' scope of the CDM .

The United States also measures and reports on the net greenhouse gas sequestration in its forests .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation . In some areas , policies designed to address global warming may contribute positively towards other development objectives .

Biolink zone was first coined in 1992 to encapsulate a potential new land-use resulting from research on vertebrate fauna of se Australia and their prospective responses to climate change ( Bennett et al. 1992 , Brereton et al. 1995 ) . Biolink zones are identified parts of the landscape where the functional ecological connectivity for biodiversity is enhanced and / or restored to provide space for species ( and consequently ecological communities ) to self adapt their distributions and abundances under changing climates through natural processes including : dispersal ; re-colonisation ; regeneration and restoration of ecological function ( Mansergh and Cheal 2007 ) . Bennett et al. ( 1992 ) was among the first attempts to unify the themes of the Earth Summit ( 1992 ) - both biodiversity and climate change - into an adaptation response for land-use change at the regional and sub-continental level . The abbreviated `` biolinks '' has become a generic term in common use and in literature ( Wilson 2009 ) reflecting a broad resonance of the original intent of the new land-use type within various communities ( land-use planners , ecologists , community groups ) . In concept , biolink zones are equivalent to the `` bold connectivity zones '' later proposed by Opdam and Wascher ( 2004 ) for adaptation to climate change and are consistent with restoration of habitat connectivity to alleviate past and current fragmentation in Australia ( Soule et al. 2004 ) . Hilty et al. ( 2006 ) in a global review of wildlife corridors , suggests continental scale re-connectivity ( biolinks ) as the only realistic alternative for resolution of the global conservation issues of fragmentation and climate change . In fragmented , agricultural landscapes of Australia , biolink zones have been proposed between large areas of remaining native vegetation and potential climatic refugia with future landscapes supporting 30 % > 50 % of quality native vegetation and habitats , representing new bio-cultural landscapes more resilient under future climates ( Mansergh et al. 2008 a , b ) . In more ecological intact landscapes , biolink zones become a purposeful aim of management ( agencies ) for explicit adaptation to climate change . Biolink zones can be viewed at scales from regional to continental . Establishment is compatible with carbon sequestration ( soils and vegetation ) , improved landscape resilience and as part of a more holistic adaptation response of land-use to climate change ( Mansergh 2009 ) . In terms of policy development , defined biolink zones are a key policy direction for land-use change to increase the resilience of biodiversity in adapting future climates in Victoria ( Department of Sustainability and Environment , Victoria 2009 ) .

The growth of the human population , combined with advances in harvesting technologies , has led to more intense and efficient exploitation of the environment . This has resulted in the depletion of large vertebrates from ecological communities , creating what has been termed `` empty forest '' . Defaunation differs from extinction ; it includes both the disappearance of species and declines in abundance . Defaunation effects were first implied at the Symposium of Plant-Animal Interactions at the University of Campinas , Brazil in 1988 in the context of neotropical forests . Since then , the term has gained broader usage in conservation biology as a global phenomenon . It is estimated that more than 50 percent of all wildlife has been lost in the last 40 years . in 2020 it is estimated that 68 % of the worlds wildlife will be lost .

It has been endorsed internationally by governments in different arenas , including the International Labour Organisation ( ILO ) , which adopted conclusions on this matter in 2013 and tripartite ( union-employer-government ) `` Guidelines on a Just Transition towards environmentally-sustainable economies and societies for all '' in 2015 . The Paris Climate Agreement also contains references to a Just Transition , where government commit to ensure that workers are accompanied in the transformation through the creation of decent work opportunities . The rationale for a Just Transition comes from evidence that shows that if millions of jobs can be created out of the transformation towards a clean economy , some sectors such as energy extraction and production , manufacturing , agriculture and forestry , just to mention a few , which employ today millions of workers will undergo dramatic restructuring . Just Transition policies should be therefore deployed to ensure that there is strong public support for environmental action . There is a concern that significant periods of economic restructuring in the past have often happened in a chaotic fashion leaving ordinary workers , their families and communities to bear the brunt of the transition to new ways of producing wealth , leading to unemployment , poverty and exclusion . Just Transition policies For trade unions , `` Just Transition '' describes the transition towards a low‐carbon and climate‐resilient economy that maximises the benefits of climate action while minimising hardships for workers and their communities . Needs will vary in different countries , though some policies must be applied everywhere . These include : Sound investments in low‐emission and job-rich sectors and technologies . These investments must be undertaken through due consultation with all those affected , respecting human and labour rights , and Decent Work principles . Social dialogue and democratic consultation of social partners ( trade unions and employers ) and other stakeholders ( i.e. communities ) . Research and early assessment of the social and employment impacts of climate policies.Training and skills development , which are key to support the deployment of new technologies and foster industrial change . Social protection , along with active labour markets policies . Local economic diversification plans that support decent work and provide community stability in the transition . Communities should not be left on their own to manage the impacts of the transition as this will not lead to a fair distribution of costs and benefits . Definition and evolution of the Just Transition concept A summary of this evolution is contained in an article published by the International Journal on Labour Research In 1998 , a Canadian union activist , Brian Kohler , published what was going to become one of the first mentions of the Just Transition concept in a union newsletter . It constituted an attempt to reconcile the union movement 's efforts to provide workers with decent jobs and the need to protect the environment . As Kohler had clearly stated previously : `` The real choice is not jobs or environment . It is both or neither . '' In ten years , the union movement perception of environmental challenges has evolved and with it the definition , boundaries and scope of the `` just transition '' needed . Today , `` Just Transition '' can be understood as the conceptual framework in which the labour movement captures the complexities of the transition towards a low-carbon and climate-resilient economy , highlighting public policy needs and aiming to maximize benefits and minimize hardships for workers and their communities in this transformation . In a document prepared by the International Trade Union Confederation ( ITUC ) , Just Transition is defined as a `` tool the trade union movement shares with the international community , aimed at smoothing the shift towards a more sustainable society and providing hope for the capacity of a green economy to sustain decent jobs and livelihoods for all '' ( ITUC , 2009b ) . It is important to note that Just Transition is a supporting mechanism of climate action , and not inaction . Just Transition is not in opposition to , but complements environmental policies . This comforts the idea that environmental and social policies are not contradictory but , on the contrary , can reinforce each other . This approach to the Just Transition concept was unanimously adopted at the 2nd ITUC Congress , in 2010 , when the Congress declared `` Just Transition '' to be `` the '' approach to fight climate change : 5 . Early mentions of Just Transition can also be found in ICFTU : ` Plough to Plate ' Approaches to Food and Agriculture , 2000 ; ICFTU : Fashioning A New Deal -- Workers and Trade Unions at the World Summit for Sustainable Development , 2002 . International Journal of Labour Research 2010 Vol . 2 Issue 2 142 Congress is committed to promoting an integrated approach to sustainable development through a just transition where social progress , environmental protection and economic needs are brought into a framework of democratic governance , where labour and other human rights are respected and gender equality achieved ( ITUC , 2010 ) . Other Global Union Federations , representing workers in specific economic sectors , joined this policy approach . The International Transport workers ' Federation ( ITF ) adopted , at its 2010 Congress , a resolution stating that `` while the urgent adoption of these policies is vital to tackle climate change , the ITF and its affiliates must defend the interests of transport workers by fighting to ensure that these policies are implemented in a way which protects jobs and creates new ones through a process of just transition '' ( ITF , 2010 ) . Federations of industrial workers have also voiced their positions on Just Transition . The International Federation of Chemical , Energy , Mine and General Workers ' Unions ( ICEM ) , for example , states that `` with a Just Transition , we can build a public consensus to move towards more sustainable production '' ( ICEM , 2009 ) . The Just Transition framework is a package of policy proposals which addresses the different aspects related to the vulnerability of workers and their communities : uncertainties regarding job impacts , risks of job losses , risks of undemocratic decision-making processes , risks of regional or local economic downturn , among others . A concept whose use has broadened In the past years , we have seen a number of organisations ( environmental and climate justice , foundations ) use the concept of Just Transition .

The UNFCCC objective is to `` stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system '' . The framework sets no binding limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms . Instead , the framework outlines how specific international treaties ( called `` protocols '' or `` Agreements '' ) may be negotiated to specify further action towards the objective of the UNFCCC . Initially an Intergovernmental Negotiating Committee ( INC ) produced the text of the Framework Convention during its meeting in New York from 30 April to 9 May 1992 . The UNFCCC was adopted on 9 May 1992 , and opened for signature on 4 June 1992 . The UNFCCC has 197 parties as of December 2015 . The convention enjoys broad legitimacy , largely due to its nearly universal membership . The parties to the convention have met annually from 1995 in Conferences of the Parties ( COP ) to assess progress in dealing with climate change . In 1997 , the Kyoto Protocol was concluded and established legally binding obligations for developed countries to reduce their greenhouse gas emissions in the period 2008-2012 . The 2010 Cancún agreements state that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . The Protocol was amended in 2012 to encompass the period 2013-2020 in the Doha Amendment , which - as of December 2015 - had not entered into force .

Conservation can focus on preserving diversity at genetic , species , community or whole ecosystem levels . This article will examine conservation at the species level , because mutualisms involve interactions between species . The ultimate goal of conservation at this level is to prevent the extinction of species . However , species conservation has the broader aim of maintaining the abundance and distribution of all species , not only those threatened with extinction ( van Dyke 2008 ) . Determining the value of conserving particular species can be done through the use of evolutionary significant units , which essentially attempt to prioritise the conservation of the species which are rarest , fastest declining , and most distinct genotypically and phenotypically ( Moritz 1994 , Fraser and Bernatchez 2001 ) . Mutualisms can be defined as `` interspecific interactions in which each of two partner species receives a net benefit '' ( Bronstein et al. 2004 ) . Here net benefit is defined as , a short-term increase in inclusive fitness ( IF ) . Incorporating the concept of genetic relatedness ( through IF ) is essential because many mutualisms involve the eusocial insects , where the majority of individuals are not reproductively active . The short-term component is chosen because it is operationally useful , even though the role of long-term adaptation is not considered ( de Mazancourt et al. 2005 ) . This definition of mutualism should be suffice for this article , although it neglects discussion of the many subtitles of IF theory applied to mutualisms , and the difficulties of examining short-term compared to long-term benefits , which are discussed in Foster and Wenselneers ( 2006 ) and de Mazancourt et al. ( 2005 ) respectively . Mutualisms can be broadly divided into two categories . Firstly , obligate mutualism , where two mutualistic partners are completely interdependent for survival and reproduction . Secondly , facultative mutualism , where two mutualistic partners both benefit from the mutualism , but can theoretically survive in each other 's absence . Mutualisms are remarkably common , in fact all organisms are believed to be involved in a mutualism at some point during their lives ( Bronstein et al. 2004 ) . This is particularly likely to be true for the definition of mutualism adopted here , where herbivory can paradoxically be mutualistic , for example in a situation where a plant overcompensates by producing more biomass when grazed on . Therefore , any species identified as particularly important to conserve will probably have mutualistic partners . It is beyond the purview of this article to discuss all these mutualisms , so the focus will be on specifically animal-plant mutualisms .", "qid": "487", "docid": "Mutualisms_and_conservation", "rank": 96, "score": 72384 }, { "content": "Title: Aves Argentinas Content: Aves Argentinas / Asociación Ornitológica del Plata ( in English : Argentine Birds ) , is an Argentine non-profit environmental organization dedicated to conservation and birdwatching .

Examples of deforestation include conversion of forestland to farms , ranches , or urban use . The most concentrated deforestation occurs in tropical rainforests . About 30 % of Earth 's land surface is covered by forests . Deforestation occurs for multiple reasons : trees are cut down to be used for building or sold as fuel , ( sometimes in the form of charcoal or timber ) , while cleared land is used as pasture for livestock and plantation . The removal of trees without sufficient reforestation has resulted in damage to habitat , biodiversity loss and aridity . It has adverse impacts on biosequestration of atmospheric carbon dioxide . Deforestation has also been used in war to deprive the enemy of vital resources and cover for its forces . Modern examples of this were the use of Agent Orange by the British military in Malaya during the Malayan Emergency and the United States military in Vietnam during the Vietnam War . As of 2005 , net deforestation rates have ceased to increase in countries with a per capita GDP of at least US$ 4,600 .

By avoiding the practice of deforestation , i.e. , clearing forests to provide inexpensive farmland ( also known as `` slash and burn agriculture '' ) , the world gains the significant climate benefits of not releasing carbon into the atmosphere . In addition , avoiding deforestation also allows forests to sequester carbon and scrub the air of pollutants .

Most of the key REDD + decisions were completed by 2013 , with the final pieces of the rulebook finished in 2015 . In the last two decades , various studies estimate that land use change , including deforestation and forest degradation , accounts for 12-29 % of global greenhouse gas emissions . For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) .

The fact that the rate of deforestation has remained constant over the last twenty years is misleading as one might believe that government or non-government organizations ( NGO ) interventions have been responsible for the decline , but reports indicate otherwise . Three reasons have been postulated as to why deforestation rates have remained relatively low : 1 ) the road network within the country has been gradually in decline making access to more remote areas more difficult , 2 ) political and regulatory changes have disincentivized investment in the country , and 3 ) agriculture has expanded outside of forest areas .

They are commonly planted in hedgerows around the edges of fields on farms . If designed properly , windbreaks around a home can reduce the cost of heating and cooling and save energy . Windbreaks are also planted to help keep snow from drifting onto roadways and even yards . Other benefits include contributing to a microclimate around crops ( with slightly less drying and chilling at night ) , providing habitat for wildlife , and , in some regions , providing wood if the trees are harvested . Windbreaks and intercropping can be combined in a farming practice referred to as alleycropping . Fields are planted in rows of different crops surrounded by rows of trees . These trees provide fruit , wood , or protect the crops from the wind . Alley cropping has been particularly successful in India , Africa , and Brazil , where coffee growers have combined farming and forestry . A further use for a shelterbelt is to screen a farm from a main road or motorway . This improves the farm landscape by reducing the visual incursion of the motorway , mitigating noise from the traffic and providing a safe barrier between farm animals and the road . The term `` windbreak '' is also used to describe an article of clothing worn to prevent wind chill . Americans tend to use the term `` windbreaker '' whereas Europeans favor the term `` windbreak '' . Fences called `` windbreaks '' are also used . Normally made from cotton , nylon , canvas , and recycled sails , windbreaks tend to have three or more panels held in place with poles that slide into pockets sewn into the panel . The poles are then hammered into the ground and a windbreak is formed . Windbreaks or `` wind fences '' are used to reduce wind speeds over erodible areas such as open fields , industrial stockpiles , and dusty industrial operations .

Wind power , as an alternative to burning fossil fuels , is plentiful , renewable , widely distributed , clean , produces no greenhouse gas emissions during operation , consumes no water , and uses little land . The net effects on the environment are far less problematic than those of nonrenewable power sources . Wind farms consist of many individual wind turbines which are connected to the electric power transmission network . Onshore wind is an inexpensive source of electric power , competitive with or in many places cheaper than coal or gas plants . Offshore wind is steadier and stronger than on land , and offshore farms have less visual impact , but construction and maintenance costs are considerably higher . Small onshore wind farms can feed some energy into the grid or provide electric power to isolated off-grid locations . Wind power gives variable power which is very consistent from year to year but which has significant variation over shorter time scales . It is therefore used in conjunction with other electric power sources to give a reliable supply . As the proportion of wind power in a region increases , a need to upgrade the grid , and a lowered ability to supplant conventional production can occur . Power management techniques such as having excess capacity , geographically distributed turbines , dispatchable backing sources , sufficient hydroelectric power , exporting and importing power to neighboring areas , using vehicle-to-grid strategies or reducing demand when wind production is low , can in many cases overcome these problems . In addition , weather forecasting permits the electric power network to be readied for the predictable variations in production that occur . As of 2015 , Denmark generates 40 % of its electric power from wind , and at least 83 other countries around the world are using wind power to supply their electric power grids .

Often taking the form of selective logging , the trade has been driven by high international demand for expensive , fine-grained lumber such as rosewood and ebony . Historically , logging and exporting in Madagascar have been regulated by the Malagasy government , although the logging of rare hardwoods was explicitly banned from protected areas in 2000 . Since then , government orders and memos have intermittently alternated between permitting and banning exports of precious woods . The most commonly cited reason for permitting exports is to salvage valuable wood from cyclone damage , although this reasoning has come under heavy scrutiny . This oscillating availability of Malagasy rosewood and other precious woods has created a market of rising and falling prices , allowing traders or `` timber barons '' to stockpile illegally sourced logs during periodic bans and then flood the market when the trade windows open and prices are high . The unsustainable exploitation of these tropical hardwoods , particularly rosewood from the SAVA Region , has escalated significantly since the start of the 2009 Malagasy political crisis . Thousands of poorly paid Malagasy loggers have flooded into the national parks -- especially in the northeast -- building roads , setting up logging camps , and cutting down even the most difficult to reach rosewood trees . Illegal activities are openly flaunted , armed militia have descended upon local villages , and a rosewood mafia easily bribe government officials , buying export permits with ease . These illegal operations are funded in part by advance payments for future shipments ( financed by Chinese expatriates and Chinese importers ) and by loans from large , international banks . Demand is fueled mostly by a growing Chinese middle class and their desire for exotic imperial-style furniture . European and American demand for high-end musical instruments and furniture have also played a role . However , public scrutiny has put significant pressure on shipping companies involved in the trade , and the United States is starting to enforce the Lacey Act by investigating companies with suspected involvement in the illegal trade of Malagasy precious woods . Logging in Madagascar 's tropical rainforests has had many secondary effects , beyond the risk of depletion of rare , endemic trees .

Small remnants of rainforest are found in Odisha state . Semi-evergreen rainforest is more extensive than the evergreen formation partly because evergreen forests tend to degrade to semi-evergreen with human interference . There are substantial differences in both the flora and fauna between the three major rainforest regions . The Western Ghats monsoon forests occur both on the western ( coastal ) margins of the ghats and on the eastern side where there is less rainfall . These forests contain several tree species of great commercial significance ( e.g. Indian rosewood ( Dalbergia latifolia ) , Malabar Kino ( Pterocarpus marsupium ) , teak ( Tectona grandis ) and Indian laurel ( Terminalia crenulata ) ) , but they have now been cleared from many areas . In the rainforests , there is an enormous number of tree species ; at least 60 percent of the trees of the upper canopy are of species which individually contribute not more than one percent of the total number . Clumps of bamboo occur along streams or in poorly drained hollows throughout the evergreen and semi-evergreen forests of south-west India , probably in areas once cleared for transporting agriculture . The tropical vegetation of north-east India ( which includes the states of Assam , Nagaland , Manipur , Mizoram , Tripura and Meghalaya as well as the plain regions of Arunachal Pradesh ) typically occurs at elevations up to 900 m . It embraces evergreen and semi-evergreen rainforests , moist deciduous monsoon forests , riparian forests , swamps and grasslands . Evergreen rainforests are found in the Assam Valley , the foothills of the eastern Himalayas and the lower parts of the Naga Hills , Meghalaya , Mizoram and Manipur , where the rain fall exceeds 2300 mm per annum . In the Assam Valley the giant Hollong ( Dipterocarpus macrocarpus ) and Shorea assamica occur singly , occasionally attaining a girth of up to 7 m and a height of up to 50 m . The monsoon forests are mainly moist sal ( Shorea robusta ) forests , which occur widely in this region . The Andaman and Nicobar islands have tropical evergreen rainforests and tropical semi-evergreen rainforests as well as tropical monsoon forests . The dominant species of Keruing wood is Dipterocarpus grandiflorus in hilly areas , while Dipterocarpus kerrii is dominant on some islands in the southern parts of the archipelago . The monsoon forests of the Andamans are dominated by the Andaman Redwood ( Pterocarpus dalbergioides ) and Terminalia spp '' . Tropical forests in India 's east present a total contrast with the pine and coniferous woodland of the Western Himalayas . The natural cover of India varies with altitude ; these evergreen forests are bounded with high alpine meadows nearer to the snowline and temperate forests of short stout trees at lower elevations . In the Himalayan foothills are deciduous trees , with shrubs , bamboo , ferns and grass . India 's northern plains , the course of the holy rivers Ganges and Yamuna ; the Thar Desert in the west ; the Sundarbans , the marshy swamplands , in the delta of the Ganges and the Brahmaputra , in the east ; the Deccan Plateau , lying in the rain shadow of the hills and the Western Ghats with their dense ; luxuriant forests -- all provide fascinating variations in habitats . These forests sustain 350 species of mammals , 2,100 kinds of birds ( both local and migratory ) , nearly 350 species of reptile and countless insects . The need for conservation of the environment and the forests has exercised the minds of Indian rulers from the earliest of times . In recent times , it was the administrators and princely rulers who demarcated and reserved forests as private preserves . Today many of the forested regions form the nucleus of India 's wildlife sanctuaries and parks .

Together , India and these countries account for 67 percent of total forest area of the world . India 's forest cover grew at 0.22 % annually over 1990-2000 , and has grown at the rate of 0.46 % per year over 2000-2010 , after decades where forest degradation was a matter of serious concern . As of 2010 , the Food and Agriculture Organisation of the United Nations estimates India 's forest cover to be about 68 million hectares , or 22 % of the country 's area . The 2013 Forest Survey of India states its forest cover increased to 69.8 million hectares by 2012 , per satellite measurements ; this represents an increase of 5,871 square kilometers of forest cover in 2 years . However , the gains were primarily in northern , central and southern Indian states , while northeastern states witnessed a net loss in forest cover over 2010 to 2012 . In 2002 , forestry industry contributed 1.7 % to India 's GDP . In 2010 , the contribution to GDP dropped to 0.9 % , largely because of rapid growth of the economy in other sectors and the government 's decision to reform and reduce import tariffs to let imports satisfy the growing Indian demand for wood products . India produces a range of processed forest ( wood and non-wood ) products ranging from wood panel products and wood pulp to make bronze , rattazikistan ware and pern resin .

India 's wood-based processing industries consumed about 30 million cubic metres of industrial wood in 2002 . India annually consumes an additional 270 million tonnes of fuelwood , 2800 million tonnes of fodder , and about 102 million cubic meter of forest products - valued at about a year . India is one of the world 's largest consumer of fuel-wood . India 's consumption of fuel-wood is about five times higher than what can be sustainably removed from forests . However , a large percentage of this fuel-wood is grown as biomass remaining from agriculture , and is managed outside forests . Fuel-wood meets about 40 % of the energy needs of the country . Around 80 % of rural people and 48 % of urban people use fuel-wood . Unless India makes major , rapid and sustained effort to expand electricity generation and power plants , the rural and urban poor in India will continue to meet their energy needs through unsustainable destruction of forests and fuel wood consumption .

Forestry in India is more than just about wood and fuel . India has a thriving non-wood forest products industry , which produces latex , gums , resins , essential oils , flavours , fragrances and aroma chemicals , incense sticks , handicrafts , thatching materials and medicinal plants . About 60 % of non-wood forest products production is consumed locally . About 50 % of the total revenue from the forestry industry in India is in non-wood forest products category .

This format was followed in subsequent Assessment Reports . The executive summary of the policymakers ' summary of the WG I report includes : We are certain of the following : there is a natural greenhouse effect ... ; emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases : CO2 , methane , CFCs and nitrous oxide . These increases will enhance the greenhouse effect , resulting on average in an additional warming of the Earth 's surface . The main greenhouse gas , water vapour , will increase in response to global warming and further enhance it . We calculate with confidence that : ... CO2 has been responsible for over half the enhanced greenhouse effect ; long-lived gases would require immediate reductions in emissions from human activities of over 60 % to stabilise their concentrations at today 's levels ... Based on current models , we predict : under -LSB- BAU -RSB- increase of global mean temperature during the -LSB- 21st -RSB- century of about 0.3 oC per decade ( with an uncertainty range of 0.2 to 0.5 oC per decade ) ; this is greater than that seen over the past 10,000 years ; under other ... scenarios which assume progressively increasing levels of controls , rates of increase in global mean temperature of about 0.2 oC -LSB- to -RSB- about 0.1 oC per decade . There are many uncertainties in our predictions particularly with regard to the timing , magnitude and regional patterns of climate change , due to our incomplete understanding of : sources and sinks of GHGs ; clouds ; oceans ; polar ice sheets . Our judgement is that : global mean surface air temperature has increased by 0.3 to 0.6 oC over the last 100 years ... ; The size of this warming is broadly consistent with predictions of climate models , but it is also of the same magnitude as natural climate variability . Thus the observed increase could be largely due to this natural variability ; alternatively this variability and other human factors could have offset a still larger human-induced greenhouse warming . The unequivocal detection of the enhanced greenhouse effect is not likely for a decade or more . under the IPCC business as usual emissions scenario , an average rate of global mean sea level rise of about 6 cm per decade over the next century ( with an uncertainty range of 3 -- 10 cm per decade ) , mainly due to thermal expansion of the oceans and the melting of some land ice .

About the same time , Paul and Hattie Barth started a church . The Barths became editors of The Bridegroom 's Messenger . In 1918 , they began Beulah Heights Bible School in Atlanta , and in 1921 they organized an association that became the International Pentecostal Assemblies . John Stroup , a member of the Methodist Protestant Church , professed receiving the baptism of the Holy Ghost in 1908 . Stroup was one of the first individuals to take the Pentecostal message into southern Ohio and parts of Kentucky . He organized the Pentecostal Church of Christ in Flatwoods , Kentucky in 1917 . The body originally headquartered in Ashland , Kentucky , and later in London , Ohio . In 1976 , the International Pentecostal Assemblies and the Pentecostal Church of Christ merged to become the International Pentecostal Church of Christ . Headquarters are located in London , Ohio . The church operates two youth camps , and six departments - Education , Global Missions , Home Missions and Evangelism , Christian Education , National Youth , and Women 's Ministries . Publications of the church are The Bridegroom 's Messenger ( considered the oldest Pentecostal periodical in the world ) and The Pentecostal Leader , a training magazine . Doctrines are detailed in a 19-article Statement of Faith ranging from the inspiration of the Scriptures to tithes and offerings . The IPCC is one of the only Pentecostal and Evangelical denominations to elevate the issue of racism to their statement of faith . The church holds two ordinances - water baptism by immersion , and holy communion . The denomination has two practices that are encouraged within the local church - foot washing , and child dedication . The body is Trinitarian , and , like many related bodies , holds that speaking in tongues is the initial evidence of the baptism of the Holy Ghost . Its affiliations are with the Pentecostal/Charismatic Churches of North America , Pentecostal World Conference , a charter member of the National Association of Evangelicals , and the World Evangelical Fellowship .

The agreement will enter into force when joined by at least 55 countries which together represent at least 55 percent of global greenhouse emissions . On 22 April 2016 ( Earth Day ) , 174 countries signed the agreement in New York , and began adopting it within their own legal systems ( through ratification , acceptance , approval , or accession ) . According to the organizing committee at the outset of the talks , the expected key result was an agreement to set a goal of limiting global warming to less than 2 degrees Celsius ( ° C ) compared to pre-industrial levels . The agreement calls for zero net anthropogenic greenhouse gas emissions to be reached during the second half of the 21st century . In the adopted version of the Paris Agreement , the parties will also `` pursue efforts to '' limit the temperature increase to 1.5 ° C . The 1.5 ° C goal will require zero emissions sometime between 2030 and 2050 , according to some scientists . Prior to the conference , 146 national climate panels publicly presented draft national climate contributions ( called `` Intended Nationally Determined Contributions '' , INDCs ) . These suggested commitments were estimated to limit global warming to 2.7 degrees Celsius by 2100 . For example , the EU suggested INDC is a commitment to a 40 percent reduction in emissions by 2030 compared to 1990 . The agreement establishes a `` global stocktake '' which revisits the national goals to `` update and enhance '' them every five years beginning 2023 . However , no detailed timetable or country-specific goals for emissions were incorporated into the Paris Agreement -- as opposed to the previous Kyoto Protocol .

The business was originally called Import Parts and Service . Due to business issues around purchasing parts wholesale , the partners divided the business between service and parts . Garry Small lead the service portion under the name Import Service Center and Richard Gordon lead the parts area under Import Parts Distributing . The original makeup of the parts business was English Ford , Triumph , Volkswagen and Volvo . Due to sponsorship of a Volvo race car and then competing personally in autocross and sports car racing , the need for high performance parts became urgent . A small collection of race-worthy components followed and Richard put together a catalog to capitalize on product uniqueness . The first catalog was 10 pages long and assembled from typewritten pages , Polaroid pictures and some clip-art . The business was primarily locally focused until 1971 when Road & Track magazine did an article on performance products for imported cars . IPD was mentioned and national marketing began .

In accordance with Article 28 of the Paris Agreement, a country cannot give notice of withdrawal from the agreement before three years of its start date in the relevant country, which was on November 4, 2016 in the case of the United States. The White House later clarified that the U.S. will abide by the four-year exit process. On November 4, 2019, the administration gave a formal notice of intention to withdraw, which takes 12 months to take effect. Until the withdrawal took effect, the United States was obligated to maintain its commitments under the Agreement, such as the requirement to continue reporting its emissions to the United Nations. The withdrawal took effect on November 4, 2020, one day after the 2020 U.S. presidential election.While celebrated by some members of the Republican Party, international reactions to the withdrawal were overwhelmingly negative from across the political spectrum, and the decision received substantial criticism from religious organizations, businesses, political leaders of all parties, environmentalists, and scientists and citizens from the United States and internationally.Following Trump's announcement, the governors of several U.S. states formed the United States Climate Alliance to continue to advance the objectives of the Paris Agreement at the state level despite the federal withdrawal. As of July 1, 2019, 24 states, American Samoa, and Puerto Rico have joined the alliance, and similar commitments have also been expressed by other state governors, mayors, and businesses.Trump's withdrawal from the Paris agreement will impact other countries by reducing its financial aid to the Green Climate fund. The termination of the $3 billion U.S. funding will ultimately impact climate change research and decrease society's chance of reaching the Paris Agreement goals, as well as omit U.S. contributions to the future IPCC reports.

But like most claims regarding global warming, the real effect is small, probably temporary, and most likely due to natural weather patterns
[ { "content": "Title: Regional effects of global warming Content: Regional effects of global warming are long-term significant changes in the expected patterns of average weather of a specific region due to global warming . The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases , especially carbon dioxide . When the global temperature changes , the changes in climate are not expected to be uniform across the Earth . In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores . Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years . There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere . The coast can also be considered a region , and will suffer severe impacts from sea level rise .", "qid": "492", "docid": "Regional_effects_of_global_warming", "rank": 1, "score": 142533 }, { "content": "Title: Global warming Content: Global warming , also referred to as climate change , is the observed century-scale rise in the average temperature of the Earth 's climate system and its related effects . Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' . There are significant regional differences , with Americans and Chinese ( whose economies are responsible for the greatest annual CO2 emissions ) among the least concerned .", "qid": "492", "docid": "Global_warming", "rank": 2, "score": 134662 }, { "content": "Title: Effects of global warming Content: The effects of global warming are the environmental and social changes caused ( directly or indirectly ) by human emissions of greenhouse gases .

Many impacts of climate change have already been observed , including glacier retreat , changes in the timing of seasonal events ( e.g. , earlier flowering of plants ) , and changes in agricultural productivity . Future effects of climate change will vary depending on climate change policies and social development . The two main policies to address climate change are reducing human greenhouse gas emissions ( climate change mitigation ) and adapting to the impacts of climate change . Geoengineering is another policy option . Near-term climate change policies could significantly affect long-term climate change impacts . Stringent mitigation policies might be able to limit global warming ( in 2100 ) to around 2 ° C or below , relative to pre-industrial levels . Without mitigation , increased energy demand and extensive use of fossil fuels might lead to global warming of around 4 ° C.

From a standpoint of environmental scepticism , Booker seeks to combine an analysis of the science of global warming with the consequences of political decisions to reduce emissions and claims that , as governments prepare to make radical changes in energy policies , the scientific evidence for global warming is becoming increasingly challenged . He asserts that global warming is not supported by a significant number of climate scientists , and criticises how the UN 's Intergovernmental Panel on Climate Change ( IPCC ) presents evidence and data , in particular citing its reliance on potentially inaccurate global climate models to make temperature projections . Booker concludes , `` it begins to look very possible that the nightmare vision of our planet being doomed '' may be imaginary , and that , if so , `` it will turn out to be one of the most expensive , destructive , and foolish mistakes the human race has ever made '' .

The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect . This scientific opinion is expressed in synthesis reports , by scientific bodies of national or international standing , and by surveys of opinion among climate scientists . Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys . National and international science academies and scientific societies have assessed current scientific opinion on global warming . These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change . The IPCC Fourth Assessment Report stated that : Warming of the climate system is unequivocal , as evidenced by increases in global average air and ocean temperatures , the widespread melting of snow and ice , and rising global average sea level . Most of the global warming since the mid-20th century is very likely due to human activities .

Some of the effects in temperate and polar regions will be positive and others elsewhere will be negative .

The greenhouse effect is caused by greenhouse gases that absorb sunlight . Energy from the sun that reaches Earth is either retained or sent into space . Greenhouse gases in Earth 's atmosphere such as carbon dioxide , methane , and water vapor absorb energy which cause a blanketing effect that warms the earth .

Scientists have resolved these questions decisively in favour of the view that the current warming trend exists and is ongoing , that human activity is the cause , and that it is without precedent in at least 2000 years .

Part of this radiation is directed towards the surface , warming it . The downward component of this radiation -- that is , the strength of the greenhouse effect -- will depend on the atmosphere 's temperature and on the amount of greenhouse gases that the atmosphere contains . On Earth , the atmosphere is warmed by absorption of infrared thermal radiation from the underlying surface ( heated by the sun ) , absorption of shorter wavelength radiant energy from the sun , and convective heat fluxes from the surface . Greenhouse gases in the atmosphere radiate energy , some of which is directed to the surface and lower atmosphere . The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect . Earth 's natural greenhouse effect is critical to supporting life . Human activities , primarily the burning of fossil fuels and clearing of forests , have intensified the natural greenhouse effect , causing global warming .

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction . Climate changes is projected to affect individual organisms , populations , species distributions and ecosystem composition and function both directly ( ex . Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) .

These can include or be affected by temperature , aridity , resource availability , habitat requirements , enemies , soil characteristics , competitors , and pollinators .

Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming .

Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency .

Circulation in the atmosphere and oceans is primarily driven by solar radiation and transports heat from the tropical regions to regions that receive less energy from the Sun. The water cycle also moves energy throughout the climate system. In addition, different chemical elements, necessary for life, are constantly recycled between the different components. The climate system can change due to internal variability and external forcings. These external forcings can be natural, such as variations in solar intensity and volcanic eruptions, or caused by humans.

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming .

Positive feedback amplifies the change in the first quantity while negative feedback reduces it . The term `` forcing '' means a change which may `` push '' the climate system in the direction of warming or cooling . An example of a climate forcing is increased atmospheric concentrations of greenhouse gases . By definition , forcings are external to the climate system while feedbacks are internal ; in essence , feedbacks represent the internal processes of the system . Some feedbacks may act in relative isolation to the rest of the climate system ; others may be tightly coupled ; hence it may be difficult to tell just how much a particular process contributes . Forcings , feedbacks and the dynamics of the climate system determine how much and how fast the climate changes .

Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph .

Differences in planetary boundary layer cloud modeling schemes can lead to large differences in derived values of climate sensitivity . A model that decreases boundary layer clouds in response to global warming has a climate sensitivity twice that of a model that does not include this feedback .

It involves denial , dismissal , unwarranted doubt or contrarian views which strongly depart from the scientific opinion on climate change , including the extent to which it is caused by humans , its impacts on nature and human society , or the potential of adaptation to global warming by human actions . Some deniers do endorse the term , but others often prefer the term climate change skepticism , although this is a misnomer for those who deny anthropogenic global warming . In effect , the two terms form a continuous , overlapping range of views , and generally have the same characteristics : both reject , to a greater or lesser extent , mainstream scientific opinion on climate change . Climate change denial can also be implicit , when individuals or social groups accept the science but fail to come to terms with it or to translate their acceptance into action . Several social science studies have analyzed these positions as forms of denialism . Campaigning to undermine public trust in climate science has been described as a `` denial machine '' of industrial , political and ideological interests , supported by conservative media and skeptical bloggers in manufacturing uncertainty about global warming . In the public debate , phrases such as climate skepticism have frequently been used with the same meaning as climate denialism . The labels are contested : those actively challenging climate science commonly describe themselves as `` skeptics '' , but many do not comply with common standards of scientific skepticism and , regardless of evidence , persistently deny the validity of human caused global warming . Although scientific opinion on climate change is that human activity is extremely likely to be the primary driver of climate change , the politics of global warming have been affected by climate change denial , hindering efforts to prevent climate change and adapt to the warming climate . Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none . Of the world 's countries , the climate change denial industry is most powerful in the United States . Since January 2015 , the United States Senate Committee on Environment and Public Works has been chaired by oil lobbyist and climate change denier Jim Inhofe . Inhofe is notorious for having called climate change `` the greatest hoax ever perpetrated against the American people '' and for having claimed to have debunked the alleged hoax in February 2015 when he brought a snowball with him in the Senate chamber and tossed it across the floor . Organised campaigning to undermine public trust in climate science is associated with conservative economic policies and backed by industrial interests opposed to the regulation of emissions . Climate change denial has been associated with the fossil fuels lobby , the Koch brothers , industry advocates and libertarian think tanks , often in the United States . More than 90 % of papers sceptical on climate change originate from right-wing think tanks . The total annual income of these climate change counter-movement-organizations is roughly $ 900 million . Between 2002 and 2010 , nearly $ 120 million ( # 77 million ) was anonymously donated via the Donors Trust and Donors Capital Fund to more than 100 organisations seeking to undermine the public perception of the science on climate change . In 2013 the Center for Media and Democracy reported that the State Policy Network ( SPN ) , an umbrella group of 64 U.S. think tanks , had been lobbying on behalf of major corporations and conservative donors to oppose climate change regulation . Since the late 1970s , oil companies have published research broadly in line with the standard views on global warming .

As approximately 97 % of publishing climate scientists support the consensus on anthropogenic climate change , this list represents a minority viewpoint . The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise . The balance of impacts of global warming become significantly negative at larger values of warming . These findings are recognized by the national science academies of all the major industrialized nations ; the consensus has strengthened over time and is now virtually unanimous .

The report was produced by the Foresight unit at the UK 's Government Office of Science . It became known colloquially as ` The Foresight Report ' among people working in the field of climate-linked migration . The report was led by Professor Richard Black of Sussex University . The report was one of the first assessments of all the existing evidence and research on the connections between climate change and migration . The report authors also commissioned a number of new peer reviewed articles on migration and climate change , significant adding to the evidence base of the topic . The report attracted significant media attention on its release . The report was critical of previous predictions of the number of people who could be forced to move by climate change . It argued that making such numerical predictions was impossible because attributing climate change as the sole cause of someone 's migration was difficult . The report popularized the idea of trapped populations . The report argued that as well as being forced to move by climate change impacts , people might also be forced to stay where they are . The report drew on evidence showing that as people become poorer as a result of a degraded environment , they become less able to migrate . The idea of trapped populations had been present in the academic literature for sometime , however the media attention results from the release of the report brought the idea to a wider public for the first time . The report also popularized the idea of migration as climate change adaptation . Again , the authors drew on existing academic literature on the topic .

During this period , global average temperature was about 10 C-change higher and carbon dioxide ( CO2 ) levels were approximately 1000 parts per million ( ppm ) , 2.5 times the current concentration in Earth 's atmosphere . The abundance of atmospheric carbon dioxide had a very significant impact on global climate and Earth 's natural systems as its concentration is considered one of the main factors in the development of a pronounced greenhouse Earth during the Cretaceous with a very low average global temperature gradient . As a consequence , high paleolatitudes in both hemispheres were much warmer than at present . This temperature gradient was partly responsible for the lack of continental ice sheets in polar regions . As a response to elevated global temperatures , the Earth 's hydrologic cycle was significantly enhanced due to greater volume of moisture evaporation from the surface of the ocean . In turn , the absolute sea level during this time period stood at elevations much higher than the present level . Continental encroachment of seawater formed widespread shallow seas , including expanses of epeiric seas . An increase in surface area between shallow , warm epeiric seawater and the atmosphere permits higher evaporation rates and more precipitation at various latitudes , producing a more temperate global climate . A widespread temperate climate also had significant effects on high latitude ecosystems .", "qid": "492", "docid": "Polar_forests_of_the_Cretaceous", "rank": 100, "score": 83336 } ]

Boats of all sizes in Mobile Bay were sunk or blown ashore , and despite efforts to prepare warehouses for the tidal flooding , $ 500,000 in merchandise was lost . Further east , Pensacola , Florida , endured several days of gale-force winds after the initial passage of the storm 's core ; though wind damage to homes , businesses , and trees was extensive , the worst damage resulted from storm tides along the immediate coast . Throughout the region , the hurricane severed telephone and telegraph communications . Numerous ships were lost in the Gulf of Mexico , some with their entire crews .

Although most storms likely went unrecorded , and many records have been lost , recollections of hurricane occurrences survive from some sufficiently populated coastal areas and rarely ships at sea that survived the tempests . Observation data for years before 1492 is completely unavailable because most natives of North America lacked written languages to keep records in the pre-Columbian era , and most records in written Mesoamerican languages either do not survive or have not been deciphered and translated . Scientists now regard even data from the early years of the Columbian era as suspicious because Renaissance scientists and sailors made no distinction between tropical cyclones and extratropical systems , and incomplete because European exploration of North America and European colonization of the Americas reached only scattered areas in the 16th century . However , palaeotempestological research allows reconstruction of pre-historic hurricane activity trends on timescales of centuries to millennia . A theory has been postulated that an anti-phase pattern exists between the Gulf of Mexico coast and the East Coast of the United States . During the quiescent periods , a more northeasterly position of the Azores High would result in more hurricanes being steered towards the Atlantic coast . During the hyperactive period , more hurricanes were steered towards the Gulf coast as the Azores High -- controlled by the North Atlantic Oscillation -- was shifted to a more southwesterly position near the Caribbean . In fact , few major hurricanes struck the Gulf coast during 3000 BC -- 1400 BC and again during the most recent millennium ; these quiescent intervals were separated by a hyperactive period during 1400 BC and AD 1000 , when catastrophic hurricanes frequently struck the Gulf coast , and their landfall frequencies increased by a factor of three to five . On the Atlantic coast , probability of landfalling hurricanes has doubled in the recent millennium compared to the one and a half millennia before . Using sediment samples from Puerto Rico , the Gulf coast and the Atlantic coast from Florida to New England , Michael E. Mann et al. ( 2009 ) found consistent evidence of a peak in Atlantic tropical cyclone activity during the Medieval Warm Period followed by a subsequent lull in activity .", "qid": "493", "docid": "List_of_Atlantic_hurricanes_before_1600", "rank": 45, "score": 147896 }, { "content": "Title: Mississippi Sound Content: The Mississippi Sound is a sound along the Gulf Coast of the United States .

The sound is bordered on its southern edge by the barrier islands - Cat , Ship , Horn , Petit Bois , and Dauphin . Ship , Horn , and Petit Bois Islands are part of the National Park Service 's Gulf Islands National Seashore . Those islands separate the sound from the Gulf of Mexico . The sediment of the islands was created partly by the ancient Mississippi River when the St. Bernard Lobe of the Mississippi Delta was active over two thousand years ago . The expansion of the St. Bernard subdelta slowly isolated the Mississippi Sound from ocean dynamics of the open Gulf of Mexico .

The hurricane wrought havoc to property and the environment between southwestern Florida and eastern Louisiana , though lesser effects were felt well beyond those areas . Elena developed on August 28 near Cuba , and after traveling lengthwise across the island with little impact , it entered the Gulf of Mexico and continued to strengthen . Initially projected to strike the central Gulf Coast , the hurricane unexpectedly veered toward the east on August 30 , then stalled just 50 mi ( 80 km ) west of Cedar Key , Florida . Despite predictions that Elena would continue eastward across Florida , the cyclone remained nearly stationary for about 48 hours , causing damage all along the eastern gulf with high winds and waves , before slowly moving northwest and ultimately making landfall near Biloxi , Mississippi , on September 2 as a Category 3 major hurricane . The storm quickly weakened upon moving ashore and dissipated on September 4 . The hurricane 's unpredictable shifts in direction created what was considered the largest peacetime evacuation in the nation 's history . Evacuations occurred in sequence to follow the storm 's forecast positions , and many residents and tourists along portions of the Gulf Coast were forced to leave twice in a matter of days . Preparations were generally timely and efficient , though accommodations and resources at storm shelters were stretched thin , and many refugees tried to return home against officials ' orders . About 1.25 million people fled the storm in Florida alone , contributing to a region-wide total of nearly 2 million evacuees . Tropical cyclone warnings and watches were continuously issued and adjusted , and forecasters stressed the storm 's destructive potential for days . Elena 's slow movement off western Florida resulted in severe beach erosion and damage to coastal buildings , roads , and seawalls , especially to those of old or inadequate construction . Destruction was greatest near the shore and on islands such as Cedar Key and Dog Island , though tornadoes spawned by the hurricane swept through communities and mobile home parks well inland . The hurricane devastated the Apalachicola Bay shellfish industry , killing large quantities of oysters , destroying their reefs , and leaving thousands of workers unemployed . Farther west , Dauphin Island in Alabama endured wind gusts as high as 130 mph and a significant storm surge . The island sustained some of the most significant damage inflicted by Elena , including several hundred damaged or demolished homes . The rest of the state 's coast also sustained considerable damage , and the inland pecan and soybean crops were severely diminished in Alabama and Mississippi . Over 13,000 homes were damaged in Mississippi , and 200 were destroyed .

Hurricane Betsy was an intense and destructive tropical cyclone that brought widespread damage to areas of Florida and the central United States Gulf Coast in September 1965 . The storm 's erratic nature , coupled with its intensity and minimized preparation time contributed to making Betsy the first tropical cyclone in the Atlantic basin to accrue at least $ 1 billion in damage . While the storm primarily affected areas of southern Florida and Louisiana , lesser effects were felt in The Bahamas and as far inland in the United States as the Ohio River Valley . Betsy began as a tropical depression north of French Guiana on August 27 , and strengthened as it moved in a general northwestwardly direction . After executing a slight anticyclonic loop north of the Bahamas , Betsy proceeded to move through areas of South Florida on September 8 , causing extensive crop damage . After emerging into the Gulf of Mexico , the cyclone strengthened and reached its peak intensity equivalent to that of a Category 4 hurricane on September 10 before making its final landfall near Grand Isle , Louisiana shortly thereafter . Once inland , Betsy was slow to weaken , and persisted for two more days before degenerating into an extratropical storm ; these remnants lasted until September 13 . As a developing tropical cyclone , Betsy tracked over the northern Leeward Islands , producing moderate gusts and slight rainfall , though only minimal damage was reported . After tracking over open waters for several days , Betsy had significantly strengthened upon moving through the Bahamas . There , considerable damage occurred , particularly to crops on the archipelago 's islands . For the island chain , Betsy was considered the worst hurricane since a tropical cyclone impacted the region in 1929 . Widespread power outage and property damage ensued due to the storm 's strong winds . Overall , damage on the Bahamas amounted to at least $ 14 million , and one fatality occurred . From there Betsy tracked westward and made landfall on southern Florida , where it was considered the worst tropical cyclone since a hurricane in 1926 . Betsy 's strong storm surge inundated large portions of the Florida Keys , flooding streets and causing widespread damage . The only route out of the Keys onto the mainland was cut off by the storm . In the state alone , Betsy caused $ 139 million in damage and five deaths . Betsy 's most severe impacts were felt in Louisiana , where it made landfall as a powerful Category 3 hurricane . The cyclone propelled damaging storm surge into Lake Pontchartrain , breaching levees in New Orleans and inundating several neighborhoods , most notably the Lower Ninth Ward . Strong winds caused widespread power and telecommunications outages across the region . Further inland , effects wrought by Betsy were considerably weaker , though precipitation caused by the storm extended as far northeast as Pennsylvania . Rainfall was primarily beneficial in Arkansas , though localized flooding impacted rice and cotton crops . In Kentucky and Illinois , strong winds caused moderate property damage . By the time the remnants of Betsy moved into the northeastern United States , the storm 's winds and rainfall had substantially lessened , and as such resulting wind damage was negligible while precipitation benefited crops . In total , the damage wrought by Betsy throughout its existence equated to roughly $ 1.42 billion , making it the costliest Atlantic hurricane until it was surpassed by Hurricane Camille four years later . In addition the hurricane caused 81 deaths , primarily in Louisiana .

Less than a day after formation , the system reached tropical storm intensity , followed by hurricane intensity on July 11 . Shortly after strengthening into a hurricane , Bob reached its peak intensity with maximum sustained winds of 75 mph and a minimum barometric pressure of 986 mbar ( hPa ; 29.12 inHg ) . At the same intensity , Bob made landfall west of Grand Isle , Louisiana , and rapidly weakened after moving inland . However , the resulting tropical depression persisted for several days as it paralleled the Mississippi and Ohio rivers . On July 16 , the system emerged into the western Atlantic , where it was subsequently absorbed by a nearby low-pressure area . Widespread offshore and coastal evacuations took place along the United States Gulf Coast in preparation for Hurricane Bob . Effects from the hurricane on the United States were mostly marginal and typical of a minimal hurricane . The cyclone produced a moderate storm surge , damaging some coastal installments and causing coastal inundation . Strong winds were also associated with Bob 's landfall , though no stations observed winds of hurricane force . The winds downed trees and blew out windows , in addition to causing widespread power outages . Heavy rainfall was also reported in some locations , peaking at 7.16 in in Louisiana . Further inland , the torrential rains led to flooding in Indiana , resulting in more considerable damage as opposed to the coast . Bob also spawned eight tornadoes , with two causing significant damage . Overall , Bob was responsible for one death and $ 20 million in damage .", "qid": "493", "docid": "Hurricane_Bob_(1979)", "rank": 54, "score": 145995 }, { "content": "Title: Hurricane Opal Content: Hurricane Opal was a Category 4 hurricane that caused severe damage along the northern Gulf Coast of the United States in September 1995 .

There were seven tropical storm ; three of them attained hurricane status , while none intensified into major hurricanes , which are Category 3 or higher on the modern-day Saffir -- Simpson hurricane wind scale . This had not occurred since 1940 and would not again until 1968 . Operationally , the fifth tropical storm , which existed near the Azores in early October , was not considered a tropical cyclone , but was added to HURDAT in 2014 . Although every tropical storm impacted land , effects overall were light , with less than $ 10 million ( 1946 USD ) in damage and no deaths in the United States throughout the season . The season 's most intense cyclone was the fourth hurricane . While the storm was moving northeastward offshore the East Coast of the United States , the Norwegian tanker Maril II was destroyed at sea , causing 16 drownings ; the incident could not be directly attributed to the hurricane . The second storm brought relatively minor damage to the Cape Fear region of North Carolina after striking the state early in its duration . While an extratropical cyclone , the remnants of the fifth cyclone devastated a few islands of the Azores and left 120 fishermen missing . The Florida hurricane severely damaged sugar cane in western Cuba and caused five deaths in the island nation . Additionally , the storm left $ 5.2 million in damage in Florida , mostly inflicting citrus crops .

Of the storms that made landfall , five of the season 's seven major hurricanes -- Dennis , Emily , Katrina , Rita , and Wilma -- were responsible for most of the destruction . The Mexican states of Quintana Roo and Yucatán and the US states of Florida and Louisiana were each struck twice by major hurricanes ; Cuba , the Bahamas , Haiti , Mississippi , Texas , Alabama , and Tamaulipas were each struck once and in each case brushed by at least one more . The most catastrophic effects of the season were felt on the United States ' Gulf Coast , where a 30 ft ( 10 m ) storm surge from Hurricane Katrina caused devastating flooding that destroyed most structures on the Mississippi coastline ; subsequent levee failures in New Orleans , Louisiana caused by the storm crippled the city . Furthermore , Hurricane Stan combined with an extratropical system to cause deadly mudslides across Central America , with Guatemala being hardest-hit .

Over fifty breaches in New Orleans 's hurricane surge protection were the cause of the majority of the death and destruction during Katrina on August 29 , 2005 . Eventually 80 % of the city and large tracts of neighboring parishes became flooded , and the floodwaters lingered for weeks .

All of the major studies concluded that the USACE , the designers and builders of the levee system as mandated by the Flood Control Act of 1965 , is responsible . This is mainly due to a decision to use shorter steel sheet pilings in an effort to save money . In January 2008 , Judge Stanwood Duval , U.S. District Court , ruled that despite the Corps ' role in the flooding , the agency could not be held financially liable because of sovereign immunity in the Flood Control Act of 1928 .

A day later , the storm struck South Florida as a Category 4 hurricane , its eye becoming the first and only of a major hurricane to strike Fort Lauderdale . In Florida , advance warnings and stringent building codes were credited with minimizing structural damage and reducing loss of life to 17 people , but nevertheless widespread flooding and coastal damage resulted from heavy rainfall and high tides . Many vegetable plantings , citrus groves , and cattle were submerged or drowned as the storm exacerbated already high water levels and briefly threatened to breach the dikes surrounding Lake Okeechobee . However , the dikes held firm , and evacuations were otherwise credited with minimizing the potential death toll . On the west coast of the state , the storm caused further flooding , extensive damage south of the Tampa Bay Area , and the loss of a ship at sea . On September 18 , the hurricane entered the Gulf of Mexico and threatened the Florida Panhandle , but later its track moved farther west than expected , ultimately leading to a landfall southeast of New Orleans , Louisiana . Upon making landfall , the storm killed 34 people on the Gulf Coast of the United States and produced a storm tide as high as 15.2 ft , flooding millions of square miles and destroying thousands of homes . The storm was the first major hurricane to test Greater New Orleans since 1915 , and the widespread flooding that resulted spurred flood-protection legislature and an enlarged levee system to safeguard the flood-prone area . In all , the powerful storm killed 51 people and caused $ 110 million ( 1947 US$ ) in damage .", "qid": "493", "docid": "1947_Fort_Lauderdale_hurricane", "rank": 71, "score": 142077 }, { "content": "Title: Hurricane Alex (2010) Content: Hurricane Alex was a rare June hurricane and the first tropical cyclone to develop in the 2010 Atlantic hurricane season .

At the time , Audrey had a minimum barometric pressure of 946 mbar ( hPa ; 27.91 inHg ) . The hurricane made landfall at the same intensity between the mouth of the Sabine River and Cameron , Louisiana later that day , causing unprecedented destruction across the region . Once inland , Audrey rapidly weakened and turned extratropical over Louisiana on June 28 , before fully dissipating on June 29 . Prior to making landfall , Audrey severely disrupted offshore drilling operations in the Gulf of Mexico . Damages from offshore oil facilities alone was estimated at $ 16 million . Audrey caused much of its destruction near the border between Texas and Louisiana upon its first and only landfall . The hurricane 's strong winds resulted in widespread property and infrastructural damage . Power outages also resulted from the strong winds . However , as typical with most landfalling tropical cyclones , most of the destruction at the coast was the result of the hurricane 's strong storm surge , which was amplified by Audrey 's rapid deepening just prior to landfall . The hurricane 's storm surge was reported to have peaked as high as 12 ft ( 3.7 m ) , helping to inundate coastal areas . Damage from the surge alone extended 25 mi ( 40 km ) inland . The rough seas killed nine people offshore after capsizing the boat they were in . Further inland in Louisiana , the storm spawned two tornadoes , causing additional damage . The hurricane also dropped heavy rainfall , peaking at 10.63 in ( 270 mm ) near Basile , Louisiana . In Louisiana and Texas , where Audrey first impacted , damages totaled $ 128 million . After moving inland and transitioning into an extratropical cyclone , Audrey caused additional damage across the interior United States . The storm produced 23 tornadoes across Mississippi and Alabama , causing $ 600,000 in losses and killing two people . As it moved towards the northeast , moisture associated with the extratropical remnants of Audrey intersected with a weather front over the Midwestern United States , producing record rainfall that peaked at 10.20 in ( 259.08 mm ) in Paris , Illinois . The resultant flooding resulted in ten fatalities . Elsewhere in the United States , the storm brought strong winds , causing additional damage . Further north in Canada , 15 people were killed in Ontario and Quebec . Strong winds and torrential rainfall disrupted transportation services . In Quebec , ten people were killed in the Montreal area , making Audrey the deadliest hurricane to strike the Canadian province in recorded history .

A tropical depression formed in the Caribbean Sea near Jamaica on October 15 , and intensified into a tropical storm two days later , which was named Wilma . After heading westward as a tropical depression , Wilma turned abruptly southward after becoming a tropical storm . Wilma continued intensifying , and eventually became a hurricane on October 18 . Shortly thereafter , explosive intensification occurred , and in only 24 hours , Wilma became a Category 5 hurricane with winds of 185 mph ( 295 km/h ) . Intensity slowly leveled off after becoming a Category 5 hurricane , and winds had decreased to 150 mph ( 240 km/h ) before reaching the Yucatán Peninsula on October 20 and 21 . After crossing the Yucatán Peninsula , Wilma emerged into the Gulf of Mexico as a Category 2 hurricane . As Wilma began accelerating to the northeast , gradual re-intensification occurred , and the hurricane became a Category 3 hurricane on October 24 . Shortly thereafter , Wilma made landfall in Cape Romano , Florida with winds of 120 mph ( 190 km/h ) . As Wilma was crossing Florida , it had briefly weakened back to a Category 2 hurricane , but again re-intensified as it reached the Atlantic Ocean . The hurricane intensified into a Category 3 hurricane for the final occasion , but Wilma dropped below that intensity while accelerating northeastward . By October 26 , Wilma transitioned into an extratropical cyclone southeast of Nova Scotia . Wilma made several landfalls , with the most destructive effects felt in the Yucatán Peninsula of Mexico , Cuba , and the US state of Florida . At least 62 deaths were reported , and damage is estimated at $ 29.4 billion ( 2005 USD , $ USD ) , $ 21 billion ( 2005 USD , $ USD ) of which occurred in the United States alone . As a result , Wilma is ranked as the fifth costliest storm in United States history . Wilma is the most recent major hurricane to make landfall in the contiguous United States . Hurricane Matthew in 2016 was expected to make landfall on Florida 's East Coast as a Category 4 storm , however the cyclone veered more eastward and weakened to a Category 2 , keeping the eye well offshore and continuing a record lull in major hurricane landfalls .

The cyclone slightly weakened before making landfall near Cabo San Lucas with winds of 125 mph ( 205 km/h ) . Odile gradually weakened as it tracked across the length of the Baja California Peninsula , briefly crossing into the Gulf of California before degenerating into a remnant system on September 17 . These remnants tracked northeastward across the Southwestern United States before they were no longer identifiable on September 19 . Initially , the National Hurricane Center ( NHC ) forecast that Odile would track westward and avoid land as it would curve out to sea . Accordingly , the local governments of southwestern Mexico initially posted minor weather alerts . Precautionary measures on the Baja California Peninsula began in earnest after Odile unexpectedly took a direct course towards the peninsula . Several municipalities declared a state of emergency , opening 164 shelters with a total capacity of 30,000 people . Due to the unanticipated threat of Odile , approximately 26,000 foreign tourists were stranded on the peninsula at the time of landfall .

The following day , the cyclone briefly attained tropical storm strength before moving ashore in Nicaragua and proceeding through Honduras . It reorganized into a tropical storm over the Gulf of Honduras on September 17 , but weakened back to a depression upon crossing the Yucatán Peninsula . Once over the warm waters of the Bay of Campeche , Gert quickly strengthened into a Category 2 hurricane on September 20 . The hurricane made a final landfall on the Gulf Coast of Mexico near Tuxpan , Veracruz , with peak winds of 105 mph ( 165 km/h ) . The rugged terrain quickly disrupted the cyclone 's structure , and Gert entered the Pacific Ocean as a depression near the state of Nayarit on September 21 . There , it briefly redeveloped a few strong thunderstorms before dissipating at sea five days later . Gert 's broad wind circulation produced widespread heavy rainfall across Central America through September 15 -- 17 . Combined with saturated soil from Tropical Storm Bret 's passage a month earlier , the rain triggered flooding and mudslides in numerous communities . In Costa Rica , the storm destroyed a national park and had a significant impact on the agricultural and tourism sectors . Much of the Mosquito Coast of Nicaragua and Honduras was affected , and many cities , villages , and crops in those countries were under water .

Tens of thousands were forced to evacuate , and scores of structures were demolished in what was described as the region 's worst disaster in 40 years . In the wake of the hurricane , the road networks across the affected countries were severely disrupted , hampering relief efforts in many regions . Government and emergency officials opened shelters and distributed food for the thousands that had lost their homes or sources of income .

The outer rainbands caused flooding rainfall in southern Texas , and in Louisiana , high tides flooded roads and stranded residents on Grand Isle . Moving generally to the east due to a trough , the depression intensified into a tropical storm on October 6 , and the next day reached peak winds of 70 mph while approaching the west coast of Florida . Josephine made landfall in Taylor County near peak intensity early on October 8 , and soon after became extratropical . While moving ashore , the storm produced a high storm surge reaching 9.3 ft in Suwannee . High tides flooded about 3,600 houses along the west coast . Josephine also produced heavy rainfall , which flooded hundreds of winds , and high winds , which left 400,000 people without power .

The lands of the settlement were located in central New England in what is now Massachusetts , with initial settlements situated on two natural harbors and surrounding land , about 15.4 mi apart -- the areas around the present-day cities of Salem and Boston . The territory nominally administered by the colony included much of present-day central New England , including portions of the U.S. states of Massachusetts , Maine , New Hampshire , and Connecticut . Territory claimed but never administered by the colonial government extended as far west as the Pacific Ocean . The earlier Dutch colony of New Netherlands disputed many of these claims , arguing that they held rights to lands beyond Rhode Island up to the western side of Cape Cod and the Plymouth Bay Colony . The Massachusetts Bay Colony was founded by the owners of the Massachusetts Bay Company , which included investors in the failed Dorchester Company which had established a short-lived settlement on Cape Ann in 1623 . The colony began in 1628 and was the company 's second attempt at colonization . It was successful , with about 20,000 people migrating to New England in the 1630s . The population was strongly Puritan , and its governance was dominated by a small group of leaders who were strongly influenced by Puritan religious leaders . Its governors were elected , and the electorate were limited to freemen who had been examined for their religious views and formally admitted to the local church . As a consequence , the colonial leadership exhibited intolerance to other religious views , including Anglican , Quaker , and Baptist theologies . The colonists initially had good relationships with the local Indian populations , but frictions developed which ultimately led to the Pequot War ( 1636 -- 38 ) and then to King Philip 's War ( 1675 -- 78 ) , after which most of the Indians in southern New England made peace treaties with the colonists ( apart from the Pequot tribe , whose survivors largely merged with the Narragansett and Mohegan tribes after the Pequot War ) . The colony was economically successful , engaging in trade with England and the West Indies . A shortage of hard currency in the colony prompted it to establish a mint in 1652 . Political differences with England after the English Restoration led to the revocation of the colonial charter in 1684 . King James II established the Dominion of New England in 1686 to bring all of the New England colonies under firmer crown control . The dominion collapsed after the Glorious Revolution of 1688 deposed James , and the colony reverted to rule under the revoked charter until the charter for the Province of Massachusetts Bay was issued in 1691 , which combined the Massachusetts Bay territories with those of the Plymouth Colony and proprietary holdings on Nantucket and Martha 's Vineyard . Sir William Phips arrived in 1692 bearing the charter and formally took charge of the new province .

The first observed tropical cyclone of the season , this cyclone developed from a tropical wave over the deep tropics of the Atlantic Ocean on August 18 . Initially a tropical storm , it moved west-northwestward and intensified into a Category 1 hurricane on the modern day Saffir -- Simpson hurricane wind scale by August 19 . The storm deepened significantly over the next few days , and by August 22 , it peaked as a Category 3 hurricane with maximum sustained winds of 125 mph ( 205 km/h ) . Around that time , the system began curving northwestward and later northward . By August 23 , it turned to the north-northeast and then began weakening on August 24 . Thereafter , the storm accelerated toward Atlantic Canada . Late on August 24 , the hurricane struck near Yarmouth , Nova Scotia , as a Category 2 hurricane , just before becoming extratropical . In New England , rainfall caused minor street flooding , especially in central Massachusetts and Maine , where 2.09 in of precipitation fell in the city of Portland . Of the 173-192 fatalities in Canada , most of them occurred due to damaged or missing ships , with two boats losing their entire crew . On land , Nova Scotia was impacted most significantly . Heavy rainfall washed out 20 -- 25 percent of the rail lines , which disrupted rail service . Flooding also damaged numerous roads and swept away bridges making traveling difficult . Crop damage from the hurricane was severe as the storm destroyed about half of the fruit , vegetable , and hay harvest , leaving a loss of $ 1 million . Property damage in the province was in the thousands of dollars range and there were many electrical and telephone service outages . Similar but less severe impact occurred in New Brunswick and Prince Edward Island . The storm also left minor wind damage in Newfoundland .

Some colonial land claims extended all the way to the Pacific Ocean . The first permanent settlement was the Plymouth Colony ( 1620 ) , and the second major settlement was the Massachusetts Bay Colony at Salem in 1629 .

Thus , the sponsors remained in England and played their respective political and military roles in the English Civil War and its aftermath . As a consequence , the colony struggled and , by 1644 , Fenwick agreed to merge the colony with the more vibrant Connecticut Colony a few miles up river . In 1647 , Major John Mason assumed command of Saybrook Fort , which controlled the main trade and supply route to the upper river valley .

Prior to English colonization of the area , it was inhabited by a variety of mainly Algonquian language indigenous tribes . The first permanent English settlement in New England came in 1620 with the founding of Plymouth Colony by the Pilgrims who sailed on the Mayflower . It set precedents but never grew large . A large-scale Puritan migration began in 1630 with the establishment of the Massachusetts Bay Colony , and spawned the settlement of other New England colonies . Friction with the natives erupted in the high-casualty King Philip 's War in the 1670s . Puritanism was the established religion and was strictly enforced ; dissenters were exiled . The Colony clashed with Anglican opponents in England over its religious intolerance and the status of its charter . Most people were farmers . Businessmen established wide-ranging trade links , sending ships to the West Indies and Europe , and sometimes shipping goods in violation of the Navigation Acts . These political and trade issues led to the revocation of the Massachusetts charter in 1684 . The king in 1686 established the Dominion of New England to govern all of New England to centralize royal control and weaken local government . The intensely unpopular rule by Sir Edmund Andros came to a sudden end in 1689 with an uprising sparked by the Glorious Revolution in England . The new king William III established the Province of Massachusetts Bay in 1691 , to govern a territory roughly equivalent to that of the modern state and Maine . Its governors were appointed by the crown , in contrast to the predecessor colonies , which had elected their own governors . This created friction between the colonists and the crown , which reached its height in the early days of the American Revolution in the 1760s and 1770s over issues of who could levy taxes . Massachusetts was where the American Revolutionary War began in 1775 when London tried to shut down local self-government . The commonwealth formally adopted the state constitution in 1780 , electing John Hancock its first governor . The state was the first to abolish slavery in 1783 . In the 19th century Massachusetts became America 's center of manufacturing , with the development of precision manufacturing and weaponry in Springfield , and large-scale textile mill complexes in Worcester , Haverhill , Lowell , and other communities using their rivers for power . It was a major intellectual center and center of abolitionism . The Springfield Armory made most of the weaponry for the Union in the American Civil War . After the war , immigrants from Europe flooded into the state , continuing to expand its industrial base until the 1950s , when textiles and other industries started to fade away , leaving a `` rust belt '' of empty mills and factories . Labor unions were important after the 1860s , as were big city political machines . The state 's strength as a center of education contributed to the development of an economy based on information technology and biotechnology in the later years of the 20th century , leading to the `` Massachusetts Miracle '' of the late 1980s .", "qid": "494", "docid": "History_of_Massachusetts", "rank": 65, "score": 137164 }, { "content": "Title: 2004 Myanmar cyclone Content: The 2004 Myanmar cyclone was considered the worst to strike the country since 1968 .

The storm surge affected all 57 miles of St. Tammany Parish 's coastline , including Lacombe , Mandeville and Madisonville . The storm surge in the area of the Rigolets Pass was estimated to be 16 feet , not including wave action , declining to 7 ft at Madisonville . The surge had a second peak in eastern St. Tammany as the westerly winds from the southern eye wall pushed the surge to the east , backing up at the bottleneck of the Rigolets Pass .

The failures of structures are considered by experts to be the worst engineering disaster in the history of the United States . By August 31 , 2005 , 80 % of New Orleans was flooded , with some parts under 15 ft of water . The famous French Quarter and Garden District escaped flooding because those areas are above sea level . Responsibility for the performance of the city 's levees belongs to the United States Army Corps of Engineers . The major breaches included the 17th Street Canal levee , the Industrial Canal levee , and the London Avenue Canal floodwall . These breaches caused the majority of the flooding , according to a June 2007 report by the American Society of Civil Engineers . The flood disaster halted oil production and refining which increased oil prices worldwide . Between 80 and 90 percent of the residents of New Orleans were evacuated before the hurricane struck , testifying to some of the success of the evacuation measures .

The earliest colonists of Massachusetts Bay Colony used it , and rendered it wider by driving cattle along it . The old route is still followed , for part of its length , by Massachusetts Route 9 and Massachusetts Route 126 . In lean years of the early 1630s , when the Massachusetts Bay Colony ran short of grain , Nipmuck farmers in the valley of the Connecticut River loaded some of their abundant surplus maize into birch-bark backpacks and trod a familiar route to the settlements at the mouth of the Charles River , where they traded food for European goods made of copper and iron and woollen cloth . Fur traders and the exploratory party of John Oldham ( 1633 ) penetrated this first of the trails west into the continent 's interior . In 1635 , some settlers from Watertown took this route when they removed to Wethersfield , Connecticut . In 1636 , the outcast Thomas Hooker and a hundred of his congregation , with 160 cattle , whose milk they drank en route , followed the Old Connecticut Path in a two-weeks ' journey to the Connecticut River . There they settled in a place the native Lenape people called Suckiaug , because of the blackness of its earth . They founded the English settlement of Hartford . By 1643 , documents in the village of Sudbury called this trail the `` Old Connecticut Path . '' In 1672 , with the establishment of a postal system , it became the first colonial post road . Long native usage had emphasized the easiest route , skirting the water meadows of the river bottoms and crossing streams at the most dependable fords . The Path led west along the north bank of the Charles River from New Town ( Cambridge ) to newly settled Watertown and passed through what are now Waltham and Weston , curving southward where it entered the southeasterly section of the new town of Sudbury , now set apart as Wayland , where a section of the route still bears the name `` Old Connecticut Path '' . At Wayland , the Bay Path , later the Boston Post Road , diverged from the Connecticut Path , headed west through Marlborough , Worcester and Brookfield straight toward the Connecticut River . In Sudbury the Connecticut Path was known as `` the road from Watertown to the Dunster Farm '' , for after passing along the north side of Cochituate Pond , it crossed the tract beyond that was granted to Henry Dunster , president of Harvard College , and the lands of Edmund Rice and Philemon Whale . The trail crossed the Sudbury River at `` Danforth 's Farm '' , since 1700 incorporated as Framingham , where another section ( Route 126 ) retains the name `` Old Connecticut Path '' , threading past the northern shore of Lake Cochituate . The Connecticut Path headed west , threading between the Charles and Sudbury rivers on its way to the Connecticut River . `` From Framingham the Old Connecticut Path runs southward through South Framingham , Ashland ( Megunko ) , Hopkinton ( Quansigamog ) , then through Westborough and over Fay Mountain , to the praying town of Grafton ( Hassanamesit/Hassanamisco ) , through Sutton and then beyond to Woodstock , Conn.

Moving westward across the Caribbean Sea , Janet fluctuated in intensity , but generally strengthened before reaching its peak intensity as a Category 5 hurricane with winds of 175 mph ( 280 km/h ) . The intense hurricane later made landfall at that intensity near Chetumal , Mexico on September 28 . After weakening over the Yucatán Peninsula , it moved into the Bay of Campeche , where it slightly strengthened before making its final landfall near Veracruz on September 29 . Janet quickly weakened over Mexico 's mountainous terrain before dissipating on September 30 . In its developmental stages , Janet caused $ 7.8 million in damage to the Lesser Antilles and 189 deaths in the Grenadines and Barbados .

Robert Simpson , a Weather Bureau meteorologist who had participated in Air Force hurricane reconnaissance flights as an observer , was appointed as the first director of NHRP and organized the Research Operations Base at Morrison Air Force Base ( now Palm Beach International Airport ) in West Palm Beach , FL in 1956 . During the first three years of the Project , scientists used three specially instrumented Air Force Hurricane Hunters aircraft with crews on bailment from the 55th Weather Reconnaissance Squadron . They flew missions into Hurricane Greta ( 1956 ) , Hurricane Audrey ( 1957 ) , Hurricane Daisy ( 1958 ) , and Hurricane Helene ( 1958 ) in this initial period , collecting data which delineated the structure and energy budget of hurricanes for the first time . In 1959 , the Project was moved to Miami and collocated with the Miami hurricane forecast office . Simpson left the Project to complete his doctoral degree and Robert Cecil Gentry was appointed NHRP director . The Department of Commerce leased two DC-6 aircraft and received a B-57 jet from the Air Force so that NHRP could continue to carry out airborne experiments on hurricanes . The combination of research project , forecast center , and aircraft facility was dubbed the `` National Hurricane Center '' ( NHC ) . This has caused later confusion , since 1967 the NHC name has been used exclusively by the forecast center . However the Project and Research Flight Facility ( RFF ) remained separate entities , with their own personnel , budgets , and objectives . During the 1960s , while NHRP continued to carry out research flights into Hurricane Donna ( 1960 ) , Hurricane Cleo ( 1964 ) , and Hurricane Betsy ( 1965 ) , the Project also began to create computer models of hurricane circulation , formulated a statistical track program ( NHC-64 ) , wrote a manual on hurricane forecasting , and evaluate the accuracy of track forecasts . Starting with Hurricane Esther ( 1961 ) , NHRP was heavily involved with Project STORMFURY , the U. S. Government 's experiment in hurricane modification . They seeded Hurricane Beulah in 1963 , but had to wait six more years before a suitable candidate storm entered their operational area . Late in 1964 , the Project was renamed the National Hurricane Research Laboratory in recognition of it becoming a permanent institution within the Weather Bureau .

Although Tropical Storm Arlene formed on June 28 , the season officially began on June 1 and ended on November 30 , dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin . The season 's final storm , Tropical Storm Sean , dissipated on November 11 . The season produced twenty tropical depressions , of which nineteen further intensified into tropical storms ; seven strengthened hurricanes , and four hurricanes ultimately intensified into major hurricanes . This makes 2011 the third most active hurricane season on record , along with 1887 , 1995 , and 2010 . The two most significant storms , in terms of loss of life and damage , were Hurricane Irene and Tropical Storm Lee . Hurricane Irene was a powerful and unusually large storm that made several landfalls along the East Coast of the United States after peaking with maximum sustained winds of 120 mph ( 195 km/h ) . Tropical Storm Lee was a disorganized tropical cyclone that moved ashore the coastline of Louisiana before producing historic flooding in the Northeast United States as an extratropical cyclone .

The ninth tropical depression , eighth named storm , and fourth hurricane of the 2016 Atlantic hurricane season , Hermine developed in the Florida Straits on August 28 from a long-tracked tropical wave . The precursor system dropped heavy rainfall in portions of the Caribbean , especially the Dominican Republic and Cuba . In the former , the storm damaged more than 200 homes and displaced over 1,000 people . Although some areas of Cuba recorded more than 12 in of rain , the precipitation was generally beneficial due to a severe drought . After being designated on August 29 , Hermine shifted northeastwards due to a trough over Georgia and steadily intensified into an 80 mph ( 130 km/h ) Category 1 hurricane just before making landfall in the Florida Panhandle during September 2 . After moving inland , Hermine quickly weakened and transitioned into an extratropical cyclone on September 3 near the Outer Banks of North Carolina . The remnant system meandered offshore the Northeastern United States before dissipating over southeastern Massachusetts on September 8 . In preparation of Hermine , multiple tropical cyclone warnings and watches were issued in the Southeastern United States , while state of emergencies were declared in Florida , Georgia , North Carolina , Virginia , Maryland , and New Jersey . Storm surge and heavy rainfall along the Florida gulf coast caused significant damage . In Citrus County , one of the worst areas impacted , 2,694 structures sustained damage , of which 531 suffered major damage , while damage reached about $ 102 million .

S. Weather Bureau 's effort to scientifically examine tropical cyclones in order to make better predictions . Laboratory status signified that this effort was now a permanent part of the Weather Bureau 's activities . Director R. Cecil Gentry supervised the move of NHRL from the Aviation Building near Miami International Airport , to the newly built Computer Center building on the University of Miami 's Coral Gables campus in January 1965 . They were accompanied by the Miami hurricane forecast office , and the two combined entities were known , at that time , as the National Hurricane Center ( NHC ) . The 1965 hurricane field program centered on researching Hurricane Betsy . Project STORMFURY made plans to seed Betsy to examine hurricane modification methods , but Betsy turned before entering the operational area , so instead NHRL carried out a ` dry run ' , in which no silver iodide was released . Confusion in communicating this change in plans to the press resulted in some people believing Betsy was seeded and that its subsequent track changes were a result of that . No further seeding opportunities presented themselves over the next five years , so NHRL scientists concentrated on examining hurricanes in their unmodified states . Notable hurricanes that they flew experiments in include Hurricane Inez ( 1966 ) , Hurricane Beulah ( 1967 ) , and Hurricane Gladys ( 1968 ) . They also improved on their hurricane track forecast models such as NHC-67 and SANBAR , a barotropic model developed in conjunction with Dr. Fred Sanders ( MIT ) . They refined their models of storm circulation , and used these improved versions to test STORMFURY theories . In addition to their earlier projects , they participated in international weather research projects such as BOMEX ( 1969 ) . In 1967 , the ` NHC ' name was claimed solely by the Miami hurricane forecast office . Another seeding opportunity availed itself in August 1969 , when Hurricane Debbie moved into their operational area . They carried out several seedings over two days . While they were busy in Puerto Rico , Hurricane Camille rapidly intensified and struck the Gulf coast . The outfall from that devastating storm prompted improvements in the reconnaissance fleets . NHRL carried out another seeding experiment on Hurricane Ginger ( 1971 ) , but it was a weak , disorganized system , and little change was noted . Hurricane activity in the Atlantic became decidedly slower in the 1970s , and NHRL managers tried to move STORMFURY to the Pacific . That proved politically unfeasible , and the Navy and Air Force withdrew from Project STORMFURY . NHRL turned more to theoretical studies and sought improvements to its computer models . They also participated in GATE , a massive international weather experiment held off the west coast of Africa , examining disturbances which could form into hurricanes . In 1975 , the Experimental Meteorology Laboratory was enfolded into NHRL and it became known as the National Hurricane and Experimental Meteorology Laboratory ( NHEML ) for the next six years . NHEML engaged in several cloud modification studies as hurricane activity remained low . NHEML gained access to new Orion P-3 aircraft in 1975 and 1976 to replace the DC-6s . The new airframes also had better instrumentation , including digitized radars and cloud physics probes . NHC and NHEML were moved from their University of Miami perch in 1978 to a nearby commercial office building . This move proved disruptive , as some archive material was lost and caused some long-time staff members to retire or resign ; however , the better quality data from the P-3s was analyzed by a new generation of researchers , hired to replace those who left after the move . This resulted in improved understanding of hurricane dynamics , leading to the formulation of the eyewall replacement cycle . With the decline in enthusiasm for weather modification and the end of Project STORMFURY in 1983 , a portion of the Experimental Meteorology scientists were transferred out of the NHEML to the former Environmental Research Laboratory in Boulder , Colorado , with the remaining organization once again resuming the title of NHRL . In 1984 , NHRL was renamed the Hurricane Research Division , or HRD , of the Atlantic Oceanographic and Meteorological Laboratory , or AOML . This meant moving the hurricane researchers from their offices co-located with the NHC out to NOAA 's AOML facility , located on Virginia Key , a barrier island located between downtown Miami and Key Biscayne . In August , 1992 , the facility sustained moderate damage after the passage of Hurricane Andrew , however , despite significant personal disruption of their own lives , reconnaissance flights continued into Andrew until it made a final landfall along the Louisiana coastline several days later . During the 1990s the HRD staff continued to refine its forecasting models , and despite the retirement or transfer of several long-time key research staff members , made numerous research flights into a number of notable hurricanes of that decade , including Hurricane Opal ( 1995 ) and Hurricane Georges ( 1998 ) . During the disastrous 2005 hurricane season , the organization flew ongoing missions into infamous Hurricane Katrina , which provided invaluable data that continues to be studied at their Miami facility .", "qid": "496", "docid": "National_Hurricane_Research_Laboratory", "rank": 98, "score": 95877 }, { "content": "Title: Cyclone Narelle Content: Severe Tropical Cyclone Narelle was a Category 4 cyclone in early January 2013 that brought light rains to areas in South Australia suffering from a drought and heat wave .

[ { "content": "Title: Hurricane Katrina Content: Hurricane Katrina was the costliest natural disaster and one of the five deadliest hurricanes in the history of the United States . The storm is currently ranked as the third most intense United States landfalling tropical cyclone , behind only the 1935 Labor Day hurricane and Hurricane Camille in 1969 . Overall , at least 1,245 people died in the hurricane and subsequent floods , making it the deadliest United States hurricane since the 1928 Okeechobee hurricane . Total property damage was estimated at $ 108 billion ( 2005 USD ) , roughly four times the damage wrought by Hurricane Andrew in 1992 in the United States . The eleventh named storm and fifth hurricane of the 2005 Atlantic hurricane season , Katrina originated over the Bahamas on August 23 from the interaction between a tropical wave and the remnants of Tropical Depression Ten . Early the following day , the new depression intensified into Tropical Storm Katrina . The cyclone headed generally westward toward Florida and strengthened into a hurricane only two hours before making landfall at Hallandale Beach and Aventura on August 25 . After very briefly weakening to a tropical storm , Katrina emerged into the Gulf of Mexico on August 26 and began to rapidly deepen . The storm strengthened to a Category 5 hurricane over the warm waters of the Gulf of Mexico , but weakened before making its second landfall as a Category 3 hurricane on August 29 in southeast Louisiana . The storm caused severe destruction along the Gulf coast from central Florida to Texas , much of it due to the storm surge and levee failure . Severe property damage occurred in coastal areas , such as Mississippi beachfront towns ; over 90 percent of these were flooded . Boats and casino barges rammed buildings , pushing cars and houses inland ; water reached 6 - from the beach . Over fifty breaches in New Orleans 's hurricane surge protection were the cause of the majority of the death and destruction during Katrina on August 29 , 2005 . Eventually 80 % of the city and large tracts of neighboring parishes became flooded , and the floodwaters lingered for weeks . According to a modeling exercise conducted by the U.S. Army Corps of Engineers ( USACE ) , two-thirds of the deaths in Greater New Orleans were due to levee and floodwall failure . All of the major studies concluded that the USACE , the designers and builders of the levee system as mandated by the Flood Control Act of 1965 , is responsible . This is mainly due to a decision to use shorter steel sheet pilings in an effort to save money . In January 2008 , Judge Stanwood Duval , U.S. District Court , ruled that despite the Corps ' role in the flooding , the agency could not be held financially liable because of sovereign immunity in the Flood Control Act of 1928 . Exactly ten years after Katrina , J. David Rogers , lead author of a new report in the official journal of the World Water Council concluded that the flooding during Katrina `` could have been prevented had the corps retained an external review board to double-check its flood-wall designs . '' There was also an investigation of the responses from federal , state and local governments , resulting in the resignation of Federal Emergency Management Agency ( FEMA ) director Michael D. Brown , and of New Orleans Police Department ( NOPD ) Superintendent Eddie Compass . Many other government officials were criticized for their responses , especially New Orleans Mayor Ray Nagin , Louisiana Governor Kathleen Blanco , and President George W. Bush .

The Mexican states of Quintana Roo and Yucatán and the US states of Florida and Louisiana were each struck twice by major hurricanes ; Cuba , the Bahamas , Haiti , Mississippi , Texas , Alabama , and Tamaulipas were each struck once and in each case brushed by at least one more . The most catastrophic effects of the season were felt on the United States ' Gulf Coast , where a 30 ft ( 10 m ) storm surge from Hurricane Katrina caused devastating flooding that destroyed most structures on the Mississippi coastline ; subsequent levee failures in New Orleans , Louisiana caused by the storm crippled the city . Furthermore , Hurricane Stan combined with an extratropical system to cause deadly mudslides across Central America , with Guatemala being hardest-hit . The 2005 season was the first to observe more tropical cyclones in the Atlantic than the West Pacific ; on average , the latter experiences 26 while the Atlantic only averages 12 . This event was repeated in the 2010 season ; however , the 2010 typhoon season broke the record for the fewest storms observed in a single year , while the 2005 typhoon season featured near average activity . The season officially began on June 1 , 2005 , and lasted until November 30 , although it effectively persisted into January 2006 due to continued storm activity . A record twenty-eight tropical and subtropical storms formed , of which a record fifteen became hurricanes . Of these , a record seven strengthened into major hurricanes , a record-tying five became Category 4 hurricanes and a record four reached Category 5 strength , the highest categorization for hurricanes on the Saffir-Simpson Hurricane Scale . Among these Category 5 storms were hurricanes Katrina and Wilma , respectively the costliest and the most intense Atlantic hurricanes on record . This year was also notable because the list of storm names was used up and six Greek letter names had to be used .", "qid": "498", "docid": "2005_Atlantic_hurricane_season", "rank": 2, "score": 117072 }, { "content": "Title: 1926 Miami hurricane Content: The 1926 Miami hurricane , commonly called the `` Great Miami '' hurricane , was a large and intense tropical cyclone that devastated the Greater Miami area and caused extensive damage in the Bahamas and the U.S. Gulf Coast in September 1926 , accruing a US$ 78.58 million damage toll that remains the costliest in U.S. history when adjusted using inflation , population , and wealth normalization , yielding a cost of nearly US$ 165 billion . As a result of the destruction in Florida , the hurricane represented an early start to the Great Depression in the aftermath of the state 's 1920s land boom . The tropical cyclone is believed to have formed in the central Atlantic Ocean on September 11 . Steadily strengthening as it tracked west-northwestward , the tropical storm reached hurricane intensity the next day . As a result of scattered observations at open sea , however , no ship encountered the storm until September 15 , by which time the cyclone had reached major hurricane intensity north of the Virgin Islands . Strengthening continued up until the following day , when the storm reached peak intensity with a strength equivalent to a Category 4 hurricane . This intensity was maintained as the storm tracked across the Turks and Caicos and the Bahamas to landfall near Miami on September 18 . The cyclone caused immense destruction throughout the islands and across southern Florida . The storm destroyed hundreds of structures in its path over the islands , leaving thousands of residents homeless . At least 17 deaths occurred on the islands , though many others -- some related only indirectly to the storm -- were reported in the aftermath . Upon striking South Florida , the cyclone generated hurricane-force winds over a broad swath of the region , causing widespread and severe structural damage from both wind and water . Most of the deaths occurred near Lake Okeechobee , when a large storm surge breached muck dikes and drowned hundreds of people . The hurricane quickly traversed the Florida peninsula before emerging into the Gulf of Mexico near Fort Myers . The storm flooded surrounding communities and barrier islands , while strong winds downed trees and disrupted electrical service . The storm later made two landfalls with weaker intensities on Alabama and Mississippi on September 20 and 21 , respectively . The storm caused additional but less severe damage in those states , primarily from heavy rains and storm surge .

Hurricanes , as defined by the National Oceanic and Atmospheric Administration ( NOAA ) , are tropical cyclones -- a warm-core , non-frontal synoptic-scale cyclone , originating over tropical or subtropical waters with organized deep convection and a closed surface wind circulation about a well-defined center -- in the Atlantic , Caribbean Sea , Gulf of Mexico , or eastern Pacific , in which the maximum 1-minute sustained surface wind exceeds 64 knots or greater . The hurricanes on the list below depict the severity of the damage the system has caused . Typically , if a hurricane has caused significant damage to a particular location , its name is retired so that it will not be re-used as a name for any future hurricanes . The costliest hurricane ever recorded in the Atlantic was Hurricane Katrina , which struck the coastlines of Mississippi and Louisiana after brushing the tip of Florida , in August 2005 , causing $ 108 billion ( 2005 USD ) in property damage . The most recent , costliest hurricane was Hurricane Matthew , which struck the coastlines of Haiti , Cuba , and eastern United States , causing $ 15 billion ( 2016 USD ) in damage in September-October 2016 . A majority of the costliest Atlantic hurricanes in recorded history have peaked as major hurricanes . However , weaker tropical cyclones can still cause widespread damage . Both tropical storms Allison in 2001 and Lee in 2011 have caused over a billion in damage ; the former of which accounted for a higher damage total . Due to their excessive damage , the names of tropical cyclones accruing over $ 1 billion in damage are often retired by the World Meteorological Organization . However , this is not always the case . Hurricane Juan in 1985 was the first hurricane to cause over a billion in damage and not be retired ; its name was retired on a later usage in 2003 that did not cause over a billion in damage . Since Juan , five tropical cyclones that caused over a billion in damage were not retired , the most recent of which being Hurricane Isaac in 2012 . All other 39 Atlantic hurricanes to have caused as much damage have had their names retired . The first hurricane to cause over $ 1 billion in damage was Hurricane Betsy in 1965 , which caused much of its damage in southeastern Louisiana . Two and four years later , Hurricanes Beulah and Camille both caused at least $ 1 billion in damage . After the 1960s , each decade saw an increase in tropical cyclones causing at least a billion in damage over the last , due to increasing urban development and population . In the 1970s , four hurricanes caused over a billion in damage ; the costliest of which was Hurricane Frederic , which caused $ 2.3 billion in damage , particularly in Mississippi and Alabama . The following decade featured seven hurricanes causing in excess of a billion in damage . In the 1989 season , Hurricane Hugo was the first storm to hit $ 10 Billion US dollars in cost . In the 1990s , nine tropical cyclones accrued more than a billion in damage . Hurricane Andrew in 1992 greatly exceeded the damage figure of any preceding tropical cyclone after causing $ 26.5 billion in damage , mostly in South Florida . Seventeen tropical cyclones in the 2000s caused in excess of $ 1 billion in damage . Both 2004 and 2005 seasons had five billion-dollar hurricanes apiece , the most of any season on record . Hurricane Ivan caused at least a billion in damage in three separate countries . Thus far in the 2010s , seven storms have caused at least $ 1 billion in damage .", "qid": "498", "docid": "List_of_costliest_Atlantic_hurricanes", "rank": 5, "score": 115982 }, { "content": "Title: Hurricane Andrew Content: Hurricane Andrew was , at the time of its occurrence in August 1992 , the most destructive hurricane in United States history . It caused major damage in the Bahamas and Louisiana , but the greatest impact was in South Florida , where it made landfall at Category 5 hurricane intensity on the Saffir -- Simpson hurricane scale , with wind speeds up to 165 mph ( 270 km/h ) . Passing directly through the town of Homestead , Florida , a city south of Miami , Andrew obliterated entire blocks of homes , in many cases leaving only the concrete foundations . Over 25,500 houses were destroyed in Miami-Dade County alone , and nearly 100,000 more were severely damaged . A total of 65 people were killed and damage across the affected regions exceeded $ 26.5 billion ( 1992 USD ) . Andrew originated from a tropical wave on August 16 over the central Atlantic , becoming the fourth tropical cyclone and the first hurricane of the season . Initially , strong wind shear prevented much intensification , but after turning westward , Andrew entered a stage of rapid intensification , peaking as a powerful Category 5 hurricane near the Bahamas on August 23 . Though it briefly weakened to Category 4 strength while traversing the island nation , Andrew regained its Category 5 status before making two separate landfalls in South Florida -- the first on Elliott Key and the second in Homestead . A barometric pressure of 922 mbar ( 27.23 inHg ) in the latter made Andrew the fourth most intense hurricane to strike the United States . Several hours later , the hurricane emerged over the Gulf of Mexico at Category 4 strength , with the Gulf Coast of the United States in its projected path . After weakening slightly , Andrew moved ashore near Morgan City , Louisiana , as low-end Category 3 storm . The effects of land caused the small hurricane to rapidly lose its intensity , and it diminished to a depression by August 27 while crossing Mississippi . The next day , Andrew merged with a frontal system over the southern Appalachian Mountains . In the Bahamas , Andrew brought storm surge , hurricane-force winds , and tornadoes , causing widespread structural damage , especially on Cat Cays . About 800 houses were destroyed in the archipelago , and there was substantial damage to the transport , water , sanitation , agriculture , and fishing sectors . Overall , Andrew left four dead and $ 250 million in damage throughout the Bahamas . In parts of southern Florida , Andrew produced severe winds ; a wind gust of 177 mph ( 282 km/h ) was observed at a house in Perrine . These winds wreaked catastrophic damage in Florida -- Miami-Dade County cities of Florida City , Homestead , and Cutler Ridge receiving the brunt of the storm . A total of 63,000 homes were destroyed and more than 101,000 others were damaged throughout Florida , leaving roughly 175,000 people homeless . As many as 1.4 million people lost power at the height of the storm . In the Everglades , 70,000 acres ( 280 km2 ) of trees were downed . Rainfall in Florida was substantial , peaking at 13.98 in ( 355 mm ) in western Miami-Dade County . Altogether , Andrew killed 44 and left a record $ 25 billion in damage in the state . Before moving ashore , Andrew caused extensive damage to oil platforms in the Gulf of Mexico , leading to $ 500 million in losses for oil companies . It produced hurricane-force winds along its path through Louisiana , leaving about 152,000 without electricity . Over 80 % of trees in the Atchafalaya River Basin were downed , and the agriculture there was devastated . Throughout the basin and Bayou Lafourche , 187 million freshwater fish were killed in the hurricane . An F3 tornado in St. John the Baptist Parish wrecked 163 structures . With 23,000 houses damaged , 985 others destroyed , and 1,951 mobile homes demolished , property losses in Louisiana exceeded $ 1.5 billion . The hurricane caused the deaths of 17 people in the state , six of whom drowned offshore . Andrew spawned at least 28 tornadoes along the Gulf Coast , especially in Alabama , Georgia , and Mississippi . Throughout its path , Andrew left 65 dead and $ 26.5 billion in damage ; it is currently the fifth costliest hurricane in Atlantic hurricane history , behind only hurricanes Katrina , Sandy , Ike , and Wilma , and the fourth costliest hurricane in the United States , behind Katrina , Sandy , and Ike .", "qid": "498", "docid": "Hurricane_Andrew", "rank": 6, "score": 115429 }, { "content": "Title: 2016 Atlantic hurricane season Content: The 2016 Atlantic hurricane season was the first above average Atlantic hurricane season since 2012 , producing a total of 15 named storms , 7 hurricanes , and 4 major hurricanes .

The final storm , Otto , crossed into the Eastern Pacific on November 25 , a few days before the official end . Following Alex , Tropical Storm Bonnie brought flooding to South Carolina and portions of North Carolina . Tropical Storm Colin in early June brought minor flooding and wind damage to parts of the Southeastern United States , especially Florida . Hurricane Earl left 94 fatalities in the Dominican Republic and Mexico , 81 of which occurred in the latter . In early September , Hurricane Hermine , the first hurricane to make landfall in Florida since Hurricane Wilma in 2005 , brought extensive coastal flooding damage especially to the Forgotten and Nature coasts of Florida . Hermine was responsible for five fatalities and about $ 550 million ( 2016 USD ) in damage . The strongest , costliest , and deadliest storm of the season was Hurricane Matthew , the southernmost Category 5 Atlantic hurricane on record and the first to reach that intensity since Felix in 2007 . With at least 603 deaths attributed to it , Matthew was the deadliest Atlantic hurricane since Stan of 2005 . Furthermore , damage from Matthew is estimated to be at least $ 15.1 billion , making it the ninth costliest Atlantic hurricane on record . Hurricane Nicole became the first major hurricane to directly impact Bermuda since Hurricane Fabian in 2003 , leaving widespread but relatively minor damage on the island . The final tropical cyclone of the season -- Hurricane Otto -- brought severe flooding to Central America in November , particularly in Costa Rica and Nicaragua . Otto left 23 deaths and about $ 190 million in damage . On November 25 , the storm emerged into the Eastern Pacific basin , the first such occurrence since Hurricane Cesar -- Douglas in 1996 .

No activity was observed until late August when a hurricane triggered widespread river flooding in Puerto Rico . After moving north , this storm struck eastern New England . Hurricane `` Three '' avoided land , but its outer periphery generated gusty winds in the Outer Banks of North Carolina . On September 29 , fast-moving Hurricane `` Four '' became one of the costliest United States hurricanes on record at the time after swamping Florida 's Cedar Keys with a large storm surge and subsequently causing extensive devastation in the eastern United States . The hurricane caused 202 deaths and more than $ 9 million in damage across eight states , plus Washington , D.C. and the Great Lakes . About two weeks later , Hurricane `` Five '' roughly paralleled the U.S. East Coast , causing substantial coastal flooding and destruction of beachfront property .

There , it brought extreme winds and the lowest known atmospheric pressure of the time -- 938 mbar ( 27.70 inHg ) -- a record which remained unbroken until the development of a later cyclone in 1924 . It soon curved toward Florida , where it maintained its intensity , continuing to rapidly hasten northward along the East Coast of the United States to New England . It entered an extratropical transition while situated over New York on 13 October , producing intense Category 2-force winds and unusually little precipitation . Eventually , the gale dissipated over the Canadian Maritimes the following day as a markedly weaker storm . In Cuba , the storm caused hundreds of deaths , capsized dozens of ships , obliterated buildings , uprooted trees , and ruined crops . Many towns were wholly destroyed or flattened and never recovered , while others disappeared entirely . Damage in the United States was considerably better-chronicled despite being less severe . In Key West , widespread destruction was noted , with 40 deaths , many vessels rendered unfit , and widespread structural damage , with several buildings swept off of their foundations and hundreds of others flattened . Few supplies arrived in the following days and relief efforts were gradual , with few resources within the town 's vicinity . Along other sections of the Southeastern U.S. coast , copious rainfall and moderate winds impacted agriculture , shipping , and residences .

It also featured the highest one-minute maximum sustained winds ever recorded in a tropical cyclone . Originating from a sprawling disturbance near the Gulf of Tehuantepec in mid-October 2015 , Patricia was first classified a tropical depression on October 20 . Initial development was slow , with only modest strengthening within the first day of its classification . The system later became a tropical storm and was named Patricia , the twenty-fourth named storm of the annual hurricane season . Exceptionally favorable environmental conditions fueled explosive intensification on October 22 . A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours -- a near-record pace . The magnitude of intensification was poorly forecast and both forecast models and meteorologists suffered from record-high prediction errors . On October 23 , two Hurricane Hunter missions both revealed the storm to have acquired maximum sustained winds of 205 mph ( 335 km/h ) and a pressure of 879 mbar ( hPa ; 25.96 inHg ) . Since the peak intensity was assessed to have occurred between the missions , the National Hurricane Center ultimately estimated Patricia to have acquired winds of 215 mph ( 345 km/h ) and pressure of 872 mbar ( hPa ; 25.75 inHg ) . This ranked it just below Typhoon Tip of 1979 as the most intense tropical cyclone on record . Patricia 's exceptional intensity prompted the retirement of its name in April 2016 .

Initially forming as a tropical depression , the storm headed slowly eastward and emerged into the western Caribbean Sea on June 15 . Once in the Caribbean , the depression began to strengthen , and by the following day , it became Tropical Storm Agnes . Thereafter , Agnes slowly curved northward and passed just west of Cuba on June 17 . Early on June 18 , the storm intensified enough to be upgraded to Hurricane Agnes . Heading northward , the hurricane eventually made landfall near Panama City , Florida late on June 19 . After moving inland , Agnes rapidly weakened and was only a tropical depression when it entered Georgia . The weakening trend halted as the storm crossed over Georgia and into South Carolina . While over eastern North Carolina , Agnes re-strengthened into a tropical storm on June 21 , as a result of baroclinic activity . Early the following day , the storm emerged into the Atlantic Ocean before re-curving northwestward and making landfall near New York City as a strong tropical storm .

Prior to its final landfall , the threat that Frederic imposed on areas of the U.S. Gulf Coast triggered a mass exodus from the region larger than any other evacuation in the past . While the storm primarily impacted the U.S. states of Mississippi and Alabama , lesser effects were felt throughout the Greater and Lesser Antilles , as well as inland North America . Frederic developed from a tropical depression south of the Cape Verde Islands on August 28 , 1979 . Tracking at a steady clip westward , the primitive cyclone reached tropical storm intensity the next day . Favorable conditions in the open Atlantic allowed for Frederic to reach hurricane intensity on September 1 . However , outflow from nearby Hurricane David began to inhibit further intensification and would continue to do so for roughly a week , weakening Frederic as it tracked across the Greater Antilles . The tropical cyclone nearly dissipated over Cuba before redeveloping on September 9 near the Isle of Youth . From then on , Frederic moved northwestward , intensifying to its peak intensity in the Gulf of Mexico with winds of 135 mph ( 215 km/h ) on September 12 , shortly before making landfall on the border between Alabama and Mississippi . Over the United States , Frederic weakened for a final time before becoming extratropical in Pennsylvania on September 14 and dissipating the next day .

It became a hurricane north of Venezuela and Colombia on September 29 , before undergoing explosive intensification , ultimately reaching Category 5 intensity on October 1 at just 13.4 ° N latitude -- the lowest latitude ever recorded for a storm of this intensity in the Atlantic basin , breaking a record set by Hurricane Ivan in 2004 . Matthew weakened slightly and fluctuated in intensity while making a northward turn toward the Greater Antilles , remaining a strong Category 4 hurricane as it made its first landfall over Haiti 's Tiburon Peninsula early on October 4 , and then a second one in Cuba later that day . Matthew weakened somewhat but re-intensified as it tracked northwest , making landfall in the northern Bahamas . The storm then paralleled the coast of the southeastern United States over the next 36 hours , gradually weakening while remaining just offshore before making its fourth and final landfall over the Cape Romain National Wildlife Refuge near Myrtle Beach , South Carolina as a Category 1 hurricane on the morning of October 8 . Matthew re-emerged into the Atlantic shortly afterward , eventually completing its transition into an extratropical cyclone as it turned away from Cape Hatteras , North Carolina on October 9 . Widespread effects were felt from Matthew across its destructive path , however , the most significant impacts were felt in Haiti , with US$ 1.9 billion in damage and 546 deaths . The combination of flooding and high winds disrupted telecommunications and destroyed extensive swaths of land ; around 80 % of Jérémie sustained significant damage . Four people were killed in Cuba due to a bridge collapse , and total losses in the country amounted to US$ 2.58 billion , most of which occurred in the Guantánamo Province .

Loss and damage can result from sudden-onset events ( climate disasters , such as cyclones ) as well as slow-onset processes ( such as sea level rise ) . Loss and damage can occur in human systems ( such as livelihoods ) as well as natural systems ( such as biodiversity ) , though the emphasis in research and policy is on human impacts . Within the realm of loss and damage to human systems , a distinction is made between economic losses and non-economic losses . The main difference between the two is that non-economic losses involve things that are not commonly traded in markets . At the 18th Conference of the Parties meeting of the UNFCCC in 2012 in Doha , Qatar , it took 36 hours of negotiation between 195 nations to arrive at a plan to address loss and damage associated with adverse effects of climate change particularly in countries most vulnerable to climate change . A new website was launched at the conference by the Loss and Damage Vulnerable Countries Initiative . It described its aim as being `` the first dedicated site for news , resources and opinion on the issue of loss and damage associated with the adverse impacts of climate change '' . Examples of types of loss and damage include farmers who can no longer grow crops to eat , or grass to feed cattle , because their soil has become too salty , and fishermen who have lost their livelihoods because rivers have dried up . In popular press , and in statements by some parties in the climate negotiations , the terms loss and damage is often associated with liability and compensation . This explains why the topic raises heated debates , and tends to widen the divide between developed countries , which are historically responsible for most greenhouse gas emissions , and developing countries that are more vulnerable to impacts of climate change . For vulnerable countries , loss and damage is most of all about recognizing that past and current efforts to avoid dangerous climate change , and that there are limits and constraints to adaptation . The United Nations Framework Convention on Climate Change has developed a work programme on loss and damage which aims to find ways to address the issue in developing countries that are particularly vulnerable to the adverse effects of climate change . On 12 -- 14 September 2013 , it held a meeting in Fiji to consider how best to address loss and damage from ` slow-onset events ' . These are impacts of climate change that occur over time , such as sea-level rise , rather than in a single , destructive event . Bangladesh is already suffering from loss and damage resulting from sea-level rise , due to its flat terrain in the coastal region . At the 19th Conference of the Parties meeting of the UNFCCC in 2013 in Warsaw , Poland , the Warsaw International Mechanism for Loss and Damage associated with Climate Change Impacts was established . At the 20th Conference of the Parties in Lima , Peru ( 2014 ) , the work plan of the executive committee of the Warsaw International Mechanism was approved . The 5th Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) , published in 2013-2014 had no separate chapter on loss and damage , but WG2 Chapter 16 about adaptation limits and constraints , is very relevant for people interested in loss and damage . A qualitative data analysis ( QDA ) of what the IPCC 5th Assessment Report has to say about loss and damage surprisingly showed that the term was used much more often in statements about Annex 1 countries ( e.g. US , Australia or European countries ) than in text about non-Annex 1 countries ( most countries in Africa , Asia Latin America and the Pacific ) , which tend to be more vulnerable to impacts of climate change .

The fact that bankruptcy is generally a costly process in itself and not only a transfer of ownership implies that these costs negatively affect the total value of the firm . These costs can be thought of as a financial cost , in the sense that the cost of financing increases because the probability of bankruptcy increases . One way to understand this is to realize that when a firm goes bankrupt investors holding its debt are likely to lose part or all of their investment , and therefore investors require a higher rate of return when investing in bonds of a firm that can easily go bankrupt . This implies that an increase in debt which ends up increasing a firm 's bankruptcy probability causes an increase in these bankruptcy costs of debt . In the trade-off theory of capital structure , firms are supposedly choosing their level of debt financing by trading off these bankruptcy costs of debt against tax benefits of debt . In particular , a firm that is trying to maximize the value for its shareholders will equalize the marginal cost of debt that results from these bankruptcy costs with the marginal benefit of debt that results from tax benefits . In the personal bankruptcy there is a cost associated with filling the paperwork . For Chapter 13 Bankruptcy there is a fee of $ 281 and for Chapter 7 Bankruptcy it is $ 306 .

The traditional approach , developed by Bailey ( 1956 ) and Friedman ( 1969 ) , treats real money balances as a consumption good and inflation as a tax on real balances . This approach measures the welfare cost by computing the appropriate area under the money demand curve . Fischer ( 1981 ) and Lucas ( 1981 ) , find the cost of inflation to be low . Fischer computes the deadweight loss generated by an increase in inflation from zero to 10 percent as just 0.3 percent of GDP using the monetary base as the definition of money . Lucas places the cost of a 10 percent inflation at 0.45 percent of GDP using M1 as the measure of money . Lucas ( 2000 ) revised his estimate upward , to slightly less than 1 percent of GDP . Ireland ( 2009 ) extends this line of analysis to study the recent behavior of U.S. money demand . Structural models are a recent alternative to econometric estimates of the triangle under an estimated money demand curve . Cooley and Hansen ( 1989 ) calibrate a cash-in-advance version of a business cycle model . They find that the welfare cost of 10 per cent inflation is about 0.4 per cent of GNP .

Craig and Rocheteau ( 2008 ) argue that a search-theoretic framework is necessary for appropriately measuring the welfare cost of inflation .

In the 1980s , financial problems caused by massive expenditures in the eight-year war with Iran and damage to oil export facilities by Iran led the government to implement austerity measures , borrow heavily , and later reschedule foreign debt payments ; Iraq suffered economic losses of at least $ 80 billion from the war . After the end of hostilities , in 1988 , oil exports gradually increased with the construction of new pipelines and restoration of damaged facilities . Since mid-2009 , oil export earnings have returned to levels seen before Operation New Dawn and government revenues have rebounded , along with global oil prices . In 2011 Baghdad probably will increase oil exports above the current level of 1900000 oilbbl per day as a result of new contracts with international oil companies , but is likely to fall short of the 2400000 oilbbl per day it is forecasting in its budget . Iraq 's recent contracts with major oil companies have the potential to greatly expand oil revenues , but Iraq will need to upgrade its oil processing , pipeline , and export infrastructure to enable these deals to reach their potential . An improved security environment and an initial wave of foreign investment are helping to spur economic activity , particularly in the energy , construction , and retail sectors . Broader economic improvement , long-term fiscal health , and sustained increases in the standard of living still depend on the government passing major policy reforms and on continued development of Iraq 's massive oil reserves . Although foreign investors viewed Iraq with increasing interest in 2010 , most are still hampered by difficulties in acquiring land for projects and by other regulatory impediments . Inflation has decreased consistently since 2006 as the security situation has improved . However , Iraqi leaders remain hard pressed to translate macroeconomic gains into improved lives for ordinary Iraqis . Unemployment remains a problem throughout the country .

These measures failed to produce the intended effect and the Brazilian government floated its currency against the US dollar , which led to the dramatic decrease in its value . The devaluation also precipitated fears that the ongoing economic crisis in Asia would spread to South America , as many South American countries were heavily dependent on industrial exports from Brazil . These fears resulted in the Brazilian government adopting an austerity program in order to receive a $ 41.5 billion aid package from the International Monetary Fund and other world lenders .

A situation that has been often cited of this was the oil crisis of the 1970s , which some economists see as a major cause of the inflation experienced in the Western world in that decade . It is argued that this inflation resulted from increases in the cost of petroleum imposed by the member states of OPEC . Since petroleum is so important to industrialized economies , a large increase in its price can lead to the increase in the price of most products , raising the inflation rate . This can raise the normal or built-in inflation rate , reflecting adaptive expectations and the price/wage spiral , so that a supply shock can have persistent effects . Keynesians argue that in a modern industrial economy , many prices are sticky downward or downward inflexible , so that instead of prices for non-oil-related goods falling in this story , a supply shock would cause a recession , i.e. , rising unemployment and falling gross domestic product . It is the costs of such a recession that likely causes governments and central banks to allow a supply shock to result in inflation . They also note that though there was no deflation in the 1980s , there was a definite fall in the inflation rate during this period . Actual deflation was prevented because supply shocks are not the only cause of inflation ; in terms of the modern triangle model of inflation , supply-driven deflation was counteracted by demand-pull inflation and built-in inflation resulting from adaptive expectations and the price/wage spiral .", "qid": "499", "docid": "Cost-push_inflation", "rank": 12, "score": 82125 }, { "content": "Title: Anti-piracy measures in Somalia Content: Piracy in Somalia has been a threat to international shipping since the second phase of the civil war in Somalia in the early 21st century .

If all the resources of the economy are put into producing only oranges , there will not be any factors of production available to produce cars . So the result is an output of X number of oranges but 0 cars . The reverse is also true - if all the factors of production are used for the production of cars , 0 oranges will be produced . In between these two extremes are situations where some oranges and some cars are produced . There are three assumptions that are made in this possibility . The economy is experiencing full employment ( everyone who wants to work has a job ) , the best technology is being used and production efficiency is being maximized . So the question becomes , what is the cost of producing more oranges or cars ? If the economy is at the maximum for all inputs , then the cost of each unit will be more expensive . The economy will have to incur more variable costs , such as overtime , to produce the unit . The law also applies to switching production in a maxed out economy .

Piracy impeded the delivery of shipments and increased shipping expenses , costing an estimated $ 6.6 to $ 6.9 billion a year in global trade in 2011 according to Oceans Beyond Piracy ( OBP ) . According to the German Institute for Economic Research ( DIW ) , a veritable industry of profiteers also arose around the piracy . Insurance companies significantly increased their profits from the pirate attacks , as the firms hiked rate premiums in response . A United Nations report and several news sources have suggested that the piracy off the coast of Somalia was caused in part by illegal fishing by foreign boats taking advantage of the war , which resulted in lost fishing income to local communities . According to the DIW and the US House Armed Services Committee , the dumping of toxic waste in Somali waters by foreign vessels also severely constrained the ability of local fishermen to earn a living . In response , the fishermen began forming armed groups to stop the foreign ships . They eventually turned to hijacking commercial vessels for ransom as an alternate source of income . In 2009 , a survey by WardheerNews found that approximately 70 percent of the local coastal communities at the time `` strongly support -LSB- ed -RSB- the piracy as a form of national defense of the country 's territorial waters '' . The pirates also believed that they were protecting their fishing grounds and exacting justice and compensation for the marine resources stolen . In the absence of an effective national coast guard following the outbreak of the civil war and the subsequent disintegration of the Armed Forces , local fishermen formed organized groups in order to protect their waters . This is reflected in the names adopted by some of the pirate networks , such as the National Volunteer Coast Guard , which are testimony to the pirates ' initial motivations . However , as piracy became substantially more lucrative , other reports have speculated that financial gain became the primary motive for the pirates . Combined Task Force 150 , a multinational coalition task force , took on the role of fighting piracy off the coast of Somalia by establishing a Maritime Security Patrol Area ( MSPA ) within the Gulf of Aden . The increasing threat posed by piracy has also caused concern in India since most of its shipping trade routes pass through the Gulf of Aden . The Indian Navy responded to these concerns by deploying warships in the region on October 2008 . In September 2008 , Russia announced that it too would join international efforts to combat piracy . Some reports have also accused certain government officials in Somalia of complicity with the pirates , with authorities from the Galmudug administration in the north-central Hobyo district reportedly attempting to use pirate gangs as a bulwark against Islamist insurgents from the nation 's southern conflict zones . However , according to UN Secretary-General Ban Ki Moon , both the former and current administrations of the autonomous Puntland region in northeastern Somalia appear to be more actively involved in combating piracy . The latter measures include on-land raids on pirate hideouts , and the construction of a new naval base in conjunction with Saracen International , a UK-based South African private military contractor described by the UN Security Council as the `` most egregious threat '' to peace and security in Somalia . By the first half of 2010 , these increased policing efforts by Somali government authorities on land and international naval vessels at sea reportedly contributed to a drop in pirate attacks in the Gulf of Aden from 86 a year prior to 33 , forcing pirates to shift attention to other areas such as the Somali Basin and the wider Indian Ocean . By the end of 2011 , pirates had managed to seize only four ships off the coast of Somalia , 22 fewer than the 26 they had captured in each of the two previous years . They also attempted unsuccessful attacks on 52 other vessels , 16 fewer than the year prior . As of April 2017 , there were no major vessels or hostages remaining in pirate captivity . According to another source , there were 151 attacks on ships in 2011 , compared to 127 in 2010 -- but only 25 successful hijacks compared to 47 in 2010 . Pirates had held 10 vessels and 159 hostages in February 2012 . In 2011 , pirates earned $ 146m , an average of $ 4.87 million per ship . An estimated 3,000 to 5,000 pirates operated . By February 2012 1,000 had been captured and were going through legal processes in 21 countries . According to the European Union Naval Force ( EU NAVFOR ) , intensified naval operations had by February 2012 led to a further drop in successful pirate attacks in the Indian Ocean , with the pirates ' movements in the region at large also significantly constrained . About 25 military vessels from EU and NATO countries , China , Russia , India and Japan patrolled approximately 8.3 million km2 ( 3.2 million sq miles ) of ocean , an area about a quarter the size of Africa . On 16 July 2012 , the EU launched a new operation , EUCAP Nestor . An analysis by the Brussels-based Global Governance Institute urged the EU to commit onshore to prevent piracy . By September 2012 , the heyday of piracy in the Indian Ocean was reportedly over . Backers were now reportedly reluctant to finance pirate expeditions due to the low rate of success , and pirates were no longer able to reimburse their creditors .

Depending on many factors , especially public expectations , the fundamental state and development of the economy , and the transmission mechanism , it is likely to result in price inflation , which is usually just called `` inflation '' , which is a rise in the general level of prices of goods and services . There is general agreement among economists that there is a causal relationship between monetary inflation and price inflation . But there is neither a common view about the exact theoretical mechanisms and relationships , nor about how to accurately measure it . This relationship is also constantly changing , within a larger complex economic system . So there is a great deal of debate on the issues involved , such as how to measure the monetary base and price inflation , how to measure the effect of public expectations , how to judge the effect of financial innovations on the transmission mechanisms , and how much factors like the velocity of money affect the relationship . Thus there are different views on what could be the best targets and tools in monetary policy . However , there is a general consensus on the importance and responsibility of central banks and monetary authorities in setting public expectations of price inflation and in trying to control it . Keynesian economists believe the central bank can sufficiently assess the detailed economic variables and circumstances in real time in order to control monetary policy in detail . These economists favor monetary policies that attempt to even out the ups and downs of business cycles and economic shocks in a precise fashion . Followers of the monetarist school think that Keynesian style monetary policies produce a lot of overshooting , time-lag errors and other unwanted effects , sometimes making things even worse . They doubt the central bank 's capacity to analyse economic problems in real time and its ability to influence the economy with correct timing and the right monetary policy measures . So monetarists advocate less intrusive and complex monetary policies , like inflation targeting or a constant growth rate of money supply . Some followers of Austrian School economics advocate either the return to free markets in money , called free banking , or a 100 % gold standard and the abolition of central banks .

In economics , hyperinflation occurs when a country experiences very high and usually accelerating rates of inflation , rapidly eroding the real value of the local currency , and causing the population to minimize their holdings of local money . The population normally switches to holding relatively stable foreign currencies . Under such conditions , the general price level within an economy increases rapidly as the official currency quickly loses real value . The value of economic items remains relatively stable in terms of foreign currencies . Unlike low inflation , where the process of rising prices is protracted and not generally noticeable except by studying past market prices , hyperinflation sees a rapid and continuing increase in nominal prices , the nominal cost of goods , and in the supply of money . Typically , however , the general price level rises even more rapidly than the money supply as people try ridding themselves of the devaluing currency as quickly as possible . As this scenario happens , the real stock of money ( i.e. , the amount of circulating money divided by the price level ) decreases . Economists believe that hyperinflations are caused by large persistent government deficits financed primarily by money creation ( rather than by borrowing or by increasing taxation ) . As such , hyperinflation is often associated with some stress to the government budget , such as wars or their aftermath , sociopolitical upheavals , a collapse in export prices , or other crises that make it difficult for the government to collect tax revenue .

This pattern seemingly goes against the theory in classical economics for which real wage growth is closely tied to labor productivity changes . The phenomenon was described by William J. Baumol and William G. Bowen in the 1960s . The rise of wages in jobs without productivity gains is from the requirement to compete for employees with jobs that have experienced gains and so can naturally pay higher salaries , just as classical economics predicts . For instance , if the retail sector pays its managers 19th-century-style salaries , the managers may decide to quit to get a job at an automobile factory , where salaries are higher because of high labor productivity . Thus , managers ' salaries are increased not by labor productivity increases in the retail sector but by productivity and corresponding wage increases in other industries . The original study was conducted for the performing arts sector . Baumol and Bowen pointed out that the same number of musicians is needed to play a Beethoven string quartet today as was needed in the 19th century ; the productivity of classical music performance has not increased . On the other hand , the real wages of musicians ( like in all other professions ) have increased greatly since the 19th century . In a range of businesses , such as the car manufacturing sector and the retail sector , workers are continually becoming more productive by technological innovations to their tools and equipment . In contrast , in some labor-intensive sectors that rely heavily on human interaction or activities , such as nursing , education , or the performing arts , there is little or no growth in productivity over time . As with the string quartet example , it takes nurses the same amount of time to change a bandage or college professors the same amount of time to mark an essay in 2006 as it did in 1966 , as those types of activities rely on the movements of the human body , which can not be engineered to perform more quickly , accurately , or efficiently in the same way that a machine , such as a computer , can . Baumol 's cost disease is often used to describe consequences of the lack of growth in productivity in the quaternary sector of the economy and public services , such as public hospitals and state colleges . Since many public administration activities are heavily labor-intensive , there is little growth in productivity over time because productivity gains come essentially from a better capital technology .", "qid": "499", "docid": "Baumol's_cost_disease", "rank": 34, "score": 72093 }, { "content": "Title: Monetary overhang Content: Monetary overhang is a phenomenon in which people have money holdings because of a lack of ability to spend them .

This is similar to the concepts of inflation and deflation except that escalation is specific to an item or class of items ( not as general in nature ) , it is often not primarily driven by changes in the money supply , and it tends to be less sustained . While escalation includes general inflation related to the money supply , it is also driven by changes in technology , practices , and particularly supply-demand imbalances that are specific to a good or service in a given economy . For example , while general inflation ( e.g. , consumer price index ) in the US was less than 5 % in the 2003-2007 time period , steel prices increased ( escalated ) by over 50 % because of supply-demand imbalance . Cost escalation may contribute to a project cost overrun but it is not synonymous with it . Over long periods of time , as market supply and demand imbalances are corrected , escalation will tend to more-or-less equal inflation unless there are sustained technology or efficiency changes in a market . Escalation is usually calculated by examining the changes in price index measures for a good or service . Future escalation can be forecast using econometrics . Unfortunately , because escalation ( unlike inflation ) may occur in a micro-market , and it may be hard to measure with surveys , indices can be difficult to find . For example , the Bureau of Labor Statistics has a price index for construction wages and compensation ( what the construction contractor 's labor cost ) , but has none for the prices that owners must pay the construction contractor for their services .

Money supply data are recorded and published , usually by the government or the central bank of the country . Public and private sector analysts have long monitored changes in money supply because of the belief that it affects the price level , inflation , the exchange rate and the business cycle .

There is strong empirical evidence of a direct relation between money-supply growth and long-term price inflation , at least for rapid increases in the amount of money in the economy . For example , a country such as Zimbabwe which saw extremely rapid increases in its money supply also saw extremely rapid increases in prices ( hyperinflation ) . This is one reason for the reliance on monetary policy as a means of controlling inflation . The nature of this causal chain is the subject of contention . Some heterodox economists argue that the money supply is endogenous ( determined by the workings of the economy , not by the central bank ) and that the sources of inflation must be found in the distributional structure of the economy . In addition , those economists seeing the central bank 's control over the money supply as feeble say that there are two weak links between the growth of the money supply and the inflation rate . First , in the aftermath of a recession , when many resources are underutilized , an increase in the money supply can cause a sustained increase in real production instead of inflation .

Steadily strengthening as it tracked west-northwestward , the tropical storm reached hurricane intensity the next day . As a result of scattered observations at open sea , however , no ship encountered the storm until September 15 , by which time the cyclone had reached major hurricane intensity north of the Virgin Islands . Strengthening continued up until the following day , when the storm reached peak intensity with a strength equivalent to a Category 4 hurricane . This intensity was maintained as the storm tracked across the Turks and Caicos and the Bahamas to landfall near Miami on September 18 . The cyclone caused immense destruction throughout the islands and across southern Florida . The storm destroyed hundreds of structures in its path over the islands , leaving thousands of residents homeless . At least 17 deaths occurred on the islands , though many others -- some related only indirectly to the storm -- were reported in the aftermath . Upon striking South Florida , the cyclone generated hurricane-force winds over a broad swath of the region , causing widespread and severe structural damage from both wind and water . Most of the deaths occurred near Lake Okeechobee , when a large storm surge breached muck dikes and drowned hundreds of people . The hurricane quickly traversed the Florida peninsula before emerging into the Gulf of Mexico near Fort Myers . The storm flooded surrounding communities and barrier islands , while strong winds downed trees and disrupted electrical service . The storm later made two landfalls with weaker intensities on Alabama and Mississippi on September 20 and 21 , respectively .

The key insight of MMT is that `` monetarily sovereign government is the monopoly supplier of its currency and can issue currency of any denomination in physical or non-physical forms . As such the government has an unlimited capacity to pay for the things it wishes to purchase and to fulfill promised future payments , and has an unlimited ability to provide funds to the other sectors . Thus , insolvency and bankruptcy of this government is not possible . It can always pay '' . In sovereign financial systems , banks can create money but these `` horizontal '' transactions do not increase net financial assets as assets are offset by liabilities . `` The balance sheet of the government does not include any domestic monetary instrument on its asset side ; it owns no money . All monetary instruments issued by the government are on its liability side and are created and destroyed with spending and taxing/bond offerings , respectively . '' In addition to deficit spending , valuation effects e.g. growth in stock price can increase net financial assets . In MMT , `` vertical '' money ( see below ) enters circulation through government spending . Taxation and its legal tender power to discharge debt establish the fiat money as currency , giving it value by creating demand for it in the form of a private tax obligation that must be met . In addition , fines , fees and licenses create demand for the currency . This can be a currency issued by the government , or a foreign currency such as the euro . An ongoing tax obligation , in concert with private confidence and acceptance of the currency , maintains its value . Because the government can issue its own currency at will , MMT maintains that the level of taxation relative to government spending ( the government 's deficit spending or budget surplus ) is in reality a policy tool that regulates inflation and unemployment , and not a means of funding the government 's activities by itself .", "qid": "499", "docid": "Modern_Monetary_Theory", "rank": 63, "score": 67657 }, { "content": "Title: Impact of the Korean War on the economy of the United States Content: The impact of the Korean War on the Economy of the United States refers to the ways in which the American economy was affected by the Korean experience from 1950 to 1953 .

Historical cost is based on the stable measuring unit assumption . In some circumstances , assets and liabilities may be shown at their historical cost , as if there had been no change in value since the date of acquisition . The balance sheet value of the item may therefore differ from the real value . While historical cost is criticised for its inaccuracy ( deviation from real value ) , it remains in use in most accounting systems during low and high inflation and deflation . During hyperinflation , International Financial Reporting Standards require financial capital maintenance in units of constant purchasing power in terms of the monthly CPI as set out in IAS 29 Financial Reporting in Hyperinflationary Economies . Various corrections to historical cost are used , many of which require the use of management judgment and may be difficult to verify . The trend in most accounting standards is a move to more accurate reflection of the fair or market value , although the historical cost principle remains in use , particularly for assets of little importance . Depreciation affects the carrying value of an asset on the balance sheet . The historical cost will equal the carrying value if there has been no change recorded in the value of the asset since acquisition . Improvements may be added to the cost basis of an asset . Historical cost does not generally reflect current market valuation . Alternative measurement bases to the historical cost measurement basis , which may be applied for some types of assets for which market values are readily available , require that the carrying value of an asset ( or liability ) be updated to the market price ( mark-to-market valuation ) or some other estimate of value that better approximates the real value . Accounting standards may also have different methods required or allowed ( even for different types of balance sheet variable real value non-monetary assets or liabilities ) as to how the resultant change in value of an asset or liability is recorded , as a part of income or as a direct change to shareholders ' equity .

In the past 25 years the UK air transport industry has seen sustained growth , and the demand for passenger air travel in particular is forecast to increase more than twofold , to 465 million passengers , by 2030 . Two airports ; London Heathrow Airport and London Gatwick Airport , are amongst the top ten busiest airports in the world for international passenger traffic . Whilst more than half of all passengers travelling by air in the UK currently travel via the five London area airports , regional airports have experienced the most growth in recent years , due to the success of ` no-frills ' airlines over the last decade . The ability of the existing airport infrastructure to meet forecast demand is limited , and government policy published in 2003 supports the development of additional airport capacity by 2030 to address this . The strategy is generally based on making the best use of existing facilities , although an additional five new runways nationwide are considered to be necessary , three of them at the London airports of Stansted , Heathrow and , towards the end of the timeframe involved , Gatwick . This policy is designed to be a balanced and measured approach to the future of the air transport industry ; one that recognises both an economic advantage in providing for growth in demand for air travel and also the need to address the consequent environmental impacts . The strategy has been criticised by the House of Commons Environmental Audit Select Committee , by environmentalist and campaign groups , and in research papers , for implementing a predict and provide model that overstates the economic advantages whilst paying insufficient heed to the environmental consequences . Support for airport expansion is based on an economic case that regards the air transport industry not only as an important industry in its own right , but also as a facilitator of growth for the economy as a whole . One study predicts that the government 's strategy will realise an additional # 13 billion per annum in Gross Domestic Product ( GDP ) by 2030 . Another study which is critical of the government approach , and which favours addressing environmental impacts through increased taxation of air transport , indicates a negative economic benefit resulting from airport expansion . In 2006 the industry was responsible for over 6 per cent of all UK carbon emissions , a figure that is set to rise as demand increases . Under current strategies of emissions reduction and growth in air transport , air travel in the UK could account for up to 50 per cent of the UK carbon budget by 2050 . Industry attempts to address this issue are longer term efforts based on technological and operational improvements , whilst government policy is based on the inclusion of air transport within emissions trading schemes . Critics advocate a shift in government policy to address environmental impacts by constraining the growth in demand for air travel , primarily through the use of economic instruments to price air travel less attractively . Local environmental issues include noise and air quality , and the impact of these , particularly in the case of the former , is subject to debate .

With the launch of the Sputnik satellite by the Soviet Union , many feared that the United States was falling behind on science and technology because it relied on private wealth to fund higher education , whereas the Soviet system was believed to be generously publicly funded , more meritocratic , and more closely tied to the needs of the economy and the military . Many families were unable to borrow sufficient funds to finance a high quality education for their children , and to thereby increase their children 's earning capacity and standard of living , until after the introduction of federal student loans . As public subsidies fell and costs and quality of education increased , loans played an increasingly important role in higher education finance . Except for its military academies , the U.S. federal government does not directly operate and control higher education institutions . Instead it offers loans , grants , tax subsidies and research contracts . Land grants date back to the Morrill Act during the U.S. Civil War and direct grants to students date back to the `` G.I. Bill '' programs implemented after World War II .", "qid": "499", "docid": "College_tuition_in_the_United_States", "rank": 80, "score": 66199 }, { "content": "Title: Monetary reform Content: Monetary reform is any movement or theory that proposes a system of supplying money and financing the economy that is different from the current system .

It states that when the prices of two substitute goods , such as high and low grades of the same product , are both increased by a fixed per-unit amount such as a transportation cost or a lump-sum tax , consumption will shift toward the higher-grade product . This is true because the added per-unit amount decreases the relative price of the higher-grade product . Suppose , for example , that high-grade coffee beans are $ 3/pound and low-grade beans $ 1.50 / pound ; in this example , high-grade beans cost twice as much as low-grade beans . Now add a per-pound international shipping cost of $ 1 . The effective prices are now $ 4 and $ 2.50 ; high-grade beans now cost only 1.6 times as much as low-grade beans . This reduced ratio of difference will induce distant coffee-buyers to now choose a higher ratio of high-to-low grade beans than local coffee-buyers . ( Prices are illustrative only ) . The effect has been studied as it applies to illegal drugs and it has been shown that the potency of marijuana increased in response to higher enforcement budgets , and there was a similar effect for alcohol in the U.S. during Prohibition .

Some areas experienced their largest snowfall levels in 18 years . Snow fell over much of Western Europe . The United Kingdom 's Met Office and Ireland 's Met Éireann issued severe weather warnings in anticipation of the snowfall . More than 30 cm of snow fell on parts of the North Downs and over 20 cm in parts of the London area . Such snow accumulation is uncommon in London . On the morning of 6 February the majority of Great Britain and Ireland had snow cover , with the area surrounding the Bristol Channel ( South Wales ( Cardiff area ) and South West England ( Bristol area ) ) being most affected -- 55 cm had settled overnight around Okehampton , Devon , South West England with similar depths in South Wales . In Ireland the highest totals were recorded around East Kildare and Wicklow County 's were up to 11 inches ( 28 cm ) fell around Naas , County Kildare and even more along the Wicklow Mountains . The last time such widespread snowfall affected Britain was in February 1991 . On the 2nd a total of 32 cm had fallen in Leatherhead , Surrey just south of the M25 . Also 30 cm had fallen over the South Downs and 26 cm in higher areas of Brighton . On 2 February , all London buses were removed from service and there were severe delays on London Underground . All train services on Southeastern railway services between London , Kent and East Sussex were cancelled , as were those on Southern . South West Trains operated an emergency timetable with reduced service . Severe disruption occurred on First Capital Connect services , c2c services , First Great Western services , National Express East Anglia and Eurostar services from St Pancras International . In Ireland Dublin Bus routes were also severely disrupted while in England all bus services in Brighton , Crawley and Royal Tunbridge Wells had been severely disrupted . Heathrow Airport was closed and British Airways cancelled all departures for a period . London City , Luton , Aberdeen , Bristol , Cardiff , Birmingham and Southampton were also affected . The Gatwick Express railway service was suspended . In Ireland on 5 February Dublin Airport was closed for a period to allow snow to be cleared from the runways , delaying flights . Flights at the airport were cancelled the following day . Other effects included lost work time and disruption to education . Costs , mainly in terms of lost work time , are estimated to amount to around # 1.2 billion , although this may be underestimated . The adverse weather conditions caused schools in some areas of the United Kingdom to close during 2 , 3 and 5 February in the Midlands .

They form as cyclonic windstorms associated with areas of low atmospheric pressure . They are most common in the autumn and winter months . On average , the month when most windstorms form is January . The seasonal average is 4.6 windstorms . Deep low pressure areas are relatively common over the North Atlantic , sometimes starting as nor'easter s off the New England coast , and frequently track across the North Atlantic Ocean towards western Europe , past the north coast of Britain and Ireland and into the Norwegian Sea . However , when they track further south they can affect almost any country in Europe . Commonly affected countries include the United Kingdom , Ireland , the Netherlands , Norway , the Faroe Islands and Iceland , but any country in Central Europe , Northern Europe and especially Western Europe is occasionally struck by such a storm system . The strong wind phenomena intrinsic to European windstorms , that give rise to `` damage footprints '' at the surface , can be placed into three categories , namely the `` warm jet '' , the `` cold jet '' and the `` sting jet '' . These phenomena vary in terms of physical mechanisms , atmospheric structure , spatial extent , duration , severity level , predictability , and location relative to cyclone and fronts . On average these storms cause economic damage $ 1.9 billion per year , and insurance losses of $ 1.4 billion per year ( 1990 -- 1998 ) .

Laid down in Leningrad in 1986 , and launched in October 1992 , after the breakup of the Soviet Union , it filled its designed role of keeping shipping lanes open and also carried passengers on arctic excursions . In July of 1994 Yamal took an excursion to the North Pole , with the NSF ( National Science Foundation -- USA ) , to celebrate the official maiden voyage . While at the exact north pole ( verified by GPS & Inmarsat satellite coordinates ) the crew and passengers celebrated with a barbeque -- the ambient temperature was − 23 degrees C ( − 10 degrees F ) ( wind gusts were measured at − 40 degrees C/F ) . Because of the ship 90/90 coordinates the ship captain ( Smirnov ) organized a swimming party with Mr. Will Rountree ( USA ) being recorded as the 1st person to ever swim there ( 21 Jul 94 ) -- water temperature was below freezing , ranging from − 33 to − 35 degrees C ( − 28 degrees to − 31 degrees F ) . The Yamal is equipped with a double hull . The outer hull is 48 mm thick where ice is met and 25 mm elsewhere and has a polymer coating to reduce friction . There is water ballast between the inner and outer hulls which can be shifted in order to aid icebreaking . Icebreaking is also assisted by an air bubbling system which can deliver 24 m ³ / s of air from jets 9 m below the surface . The Yamal can break ice while making way either forwards or backwards . Yamal is one of the Russian `` Arktika '' family of icebreakers , the most powerful icebreakers in the world . These ships must cruise in cold water to cool their reactors , so they can not pass through the tropics to undertake voyages in the Southern hemisphere . Yamal carries one helicopter and several Zodiac boats . Radio and satellite communications systems are installed which can provide navigation , telephone , fax , and email services . Amenities include a large dining room ( capable of holding all 100 passengers in one sitting ) , a library , passenger lounge , auditorium , volleyball court , gymnasium , heated indoor swimming pool , a sauna , and an infirmary . She is equipped with 50 passenger cabins and suites , all with toilets , exterior windows , a television , and a desk .

It can occur at any time of the year producing temperatures near the Chetco River mouth which are up to 40 F-change higher than without the air movement . It is the same phenomenon as the Santa Ana winds . On July 8 , 2008 , Brookings recorded a high temperature of 108 ° F at the airport . This was not only the highest recorded temperature in the town 's history , but also the highest recorded in Oregon on that day . The Crescent City airport , approximately 30 miles south , recorded a high temperature of 68 ° F that day . Temperatures in inland Oregon throughout the Willamette Valley reached temperatures into the mid-nineties . The Brookings Effect remained very strong and localized until July 13 , 2008 , when high temperatures in Brookings dropped to 61 ° F , which is about seven degrees lower than average during the month . This report contradicts the common idea that the Brookings Effect is a Chinook wind , as moisture does not appear to play a role in the moist adiabatic cooling of air on the windward side of a mountain range , followed by dry adiabatic warming on the lee side . In contrast , the Brookings Effect resembles a Santa Ana Wind , common in Southern California in the autumn and winter . In nearly every event observed , the Brookings Effect occurs when there is a high pressure ridge off the Pacific Northwest coast or in the Great Basin , depending on the time of year , and often a cutoff low in southern to central California , causing a northerly to easterly wind in the Brookings area . Studies have shown that the north-to-south orientation of the Chetco River mouth and the town of Brookings plays a large role in the high temperatures recorded , and the reason the effect is localized . During most of the year , a sea breeze sets up along the coastline with prevailing surface winds from the northwest . The heart of Brookings , with its orientation , is protected from this maritime flow and the warm , dry , down-sloping winds that are funneled down the coastal range into the deep Chetco River gorge can reach the coast uninfluenced by the effects of the Pacific . During the Brookings Effect , there is a strong correlation between the observed temperature in Brookings and the 850 millibar temperature ( the temperature at approximately 5000 ft ) in Medford , Oregon , as is determined by the weather balloon sensing equipment launched twice a day . Medford , located inland of Brookings , is located in a valley , surrounded by the Oregon Coast Range , the Siskiyou Mountains , and the Cascade Mountains . The surface temperature in Medford is often influenced by the mountains , but the 850 millibar temperature , well off the surface , is about even with the mountain ridges in the area , and therefore unaffected . Mesoscale easterly flow at this level will cause the same air mass to move westward toward Brookings , and studies show that high pressure induced atmospheric subsidence causes the air mass to flow down the slopes of the coastal range . The Chetco River gorge , which is very deep in some places , works as a funnel to bring the parcel to the coast . Often in the winter , temperatures in Medford may peak near 40 ° F , while temperatures in Brookings will reach the upper 70s ( 25 + ° C ) due to the effect , causing Brookings to live up to its `` banana belt '' reputation .", "qid": "502", "docid": "Brookings_effect", "rank": 81, "score": 106385 }, { "content": "Title: 2017 North India cold wave Content: North India was devastated by a cold wave during the month of January 2017 .

Very warm air pushed northward west of the Great Lakes region , and subsequently spread eastward . The intense poleward air mass movement was propelled by an unusually intense low level southerly jet that stretched from Louisiana to western Wisconsin . Once this warm surge inundated the area , a remarkably prolonged period of record setting temperatures ensued . NOAA 's National Climate Data Center reported that over 7,000 daily record high temperatures were tied or broken from 1 March through 27 March . In some places the temperature exceeded 86 ° F ( 30 ° C ) . For instance , in Grand Rapids , Michigan , the highest temperature recorded was 87 ° F on March 21 ; in Chicago a high of 87 ° F was also recorded on that same day . Records were broken in unusual ways . Chicago , for example , saw temperatures above 80 ° F every day between March 14 -- 18 , breaking records on all five days . Chicago would go on to record eight days at or above 80 ° F during the month , with many suburban areas recording an additional day in the 80s on March 19 ( that day , the city only tied its record high of 78 ° F ) . In context , the National Weather Service 's Chicago branch noted that Chicago typically averages only one day in the 80 's in April . And only once in 140 years of weather observations has April produced as many 80 ° F days as this March . In Traverse City , Michigan one day began with a low temperature ( 67 ° F ) higher than the previous record high for the day . Temperature records across much of southern Canada also were shattered . Some of the most impressive readings came from Nova Scotia on March 22 , when the mercury climbed to 30.0 C at a climate station in Lake Major , making it the highest March temperature recorded in Nova Scotia , and the third highest March temperature recorded in Canada . That same day , the temperature hit 29.2 C at Western Head , Nova Scotia . The heat reached as far east as Cape Breton Island , with the temperature climbing to 24.0 C at Sydney , Nova Scotia on March 22 , a place historically surrounded by ice-jammed waters , frigid winds , and snow in March . The week of March 18 also set record temperatures in Manitoba and much of Ontario as well as into the Maritime Provinces . Non-severe thunderstorms were reported on the evening hours of March 21 , through to the early morning hours March 22 into northern Ontario . In addition , NCEP/NCAR Reanalysis data show that the atmospheric pattern was so persistent that much of the Midwest and Northeast , and up into Ontario , had temperature departures over periods of several days to a week or more of magnitudes which would be unusual even for a single day . Averaged over the seven-day period from March 16 to March 22 inclusive , nearly the entire area of the Midwest and Northeast U.S. and most of Ontario and Quebec had temperatures 10 ° C ( 18 ° F ) or more above the 1981-2010 average . Even more dramatically , most of Iowa and Minnesota , all of Wisconsin and Michigan , and most of southeastern Ontario had seven-day mean temperatures more than 15 ° C ( 27 ° F ) above the climatological average for the same period . An 84 ° F high at Madison , WI in early March was 43 ° F above average and followed an overnight low of 60 ° F , 35 degrees above normal the daily high being more than seven standard deviations above the mean . The absolute temperature and departure statistically would be equivalent to a mid-July high at that station in excess of 125 ° F or more ; the highest temperature recorded there was 107 ° at least once during the heat waves of the middle 1930s . This mild warm spell brought out spring peepers in northern Ontario on 23 March , which are usually not heard until mid-to-late April , or sometimes early May .

Sinusoidal estimates of expected temperatures , for northern locales , usually place the lowest temperatures around January 23 and the highest around July 24 , and provide fairly accurate estimates of temperature expectations . Actual average temperatures in North America usually significantly differ twice over the course of the year : Mid-autumn temperatures tend to be warmer than predicted by the sinusoidal model , creating the impression of extended summer warmth known as Indian summer . For five days around January 25 , temperatures are usually significantly warmer than predicted by the sinusoidal estimate , and also warmer than neighboring temperatures on both sides . During this `` thaw '' period , usually lasting for about a week , temperatures are generally about 6 ° C ( 10 ° F ) above normal . This varies from year to year , and temperatures fluctuate enough that such a rise in late-January temperature would be unremarkable ; what is remarkable ( and unexplained ) is the tendency for such rises to occur more commonly in late January than in mid-January or early February , which sinusoidal estimates have to be slightly warmer . In some regions ( such as northern Canada ) this phenomenon will not be manifest as a `` thaw '' in the technical sense , since temperatures will remain below freezing . The January thaw is believed to be a weather singularity . A possible physical mechanism for such phenomena was offered in the 1950s by E.G. Bowen : he suggested that some `` calendaricities '' ( as he called them ) might be explicable in terms of meteoric particles from cometary orbits acting as ice nuclei in terrestrial clouds ; his theory then received some support from several sources . However , Bowen 's ideas later fell out of favour with the development of atmospheric dynamic modelling techniques , although one of his rainfall peaks does seem to correspond with the date of the January thaw . Data analysis has not found statistically significant support for the supposed January thaw .

There are two polar vortices in the Earth 's atmosphere , which overlie the North , and South Poles . Each polar vortex is a persistent , large-scale , low pressure zone that rotates counter-clockwise at the North Pole ( called a cyclone ) , and clockwise at the South Pole . The bases of the two polar vortices are located in the middle and upper troposphere and extend into the stratosphere . Beneath that lies a large mass of cold , dense arctic air . The vortices weaken and strengthen from year to year . When the vortex of the arctic is strong it is well defined , there is a single vortex and the arctic air is well contained ; when weaker , which it generally is , it will break into two or more vortices ; when very weak , the flow of arctic air becomes more disorganized and masses of cold arctic air can push equatorward , bringing with it a rapid and sharp temperature drop . The interface between the cold dry air mass of the pole and the warm moist air mass further south defines the location of the polar front . The polar front is centered , roughly at 60 ° latitude . A polar vortex strengthens in the winter and weakens in the summer due to its dependence on the temperature difference between the equator and the poles . The vortices span less than 1,000 kilometers ( 620 miles ) in diameter within which they rotate counter-clockwise in the Northern Hemisphere , and in a clockwise fashion in the Southern Hemisphere . As with other cyclones , their rotation is driven by the Coriolis effect . When the polar vortex is strong , there is a single vortex with a jet stream that is `` well constrained '' near the polar front . When the northern vortex weakens , it separates into two or more vortices , the strongest of which are near Baffin Island , Canada and the other over northeast Siberia . The Antarctic vortex of the Southern Hemisphere is a single low pressure zone that is found near the edge of the Ross ice shelf near 160 west longitude . When the polar vortex is strong , the mid-latitude Westerlies ( winds at the surface level between 30 ° and 60 ° latitude from the west ) increase in strength and are persistent . When the polar vortex is weak , high pressure zones of the mid latitudes may push poleward , moving the polar vortex , jet stream , and polar front equatorward . The jet stream is seen to `` buckle '' and deviate south . This rapidly brings cold dry air into contact with the warm , moist air of the mid latitudes , resulting in a rapid and dramatic change of weather known as a `` cold snap '' .

During a pole 's winter , it lies in continuous darkness , chilling the surface and causing the deposition of 25 -- 30 % of the atmosphere into slabs of CO2 ice ( dry ice ) . When the poles are again exposed to sunlight , the frozen CO2 sublimes , creating enormous winds that sweep off the poles as fast as 400 km/h . These seasonal actions transport large amounts of dust and water vapor , giving rise to Earth-like frost and large cirrus clouds . Clouds of water-ice were photographed by the Opportunity rover in 2004 . The caps at both poles consist primarily of water ice . Frozen carbon dioxide accumulates as a comparatively thin layer about one metre thick on the north cap in the northern winter only , while the south cap has a permanent dry ice cover about 8 m thick . The northern polar cap has a diameter of about 1000 km during the northern Mars summer , and contains about 1.6 million cubic km of ice , which if spread evenly on the cap would be 2 km thick . ( This compares to a volume of 2.85 million cubic km ( km3 ) for the Greenland ice sheet . ) The southern polar cap has a diameter of 350 km and a thickness of 3 km . The total volume of ice in the south polar cap plus the adjacent layered deposits has also been estimated at 1.6 million cubic km . Both polar caps show spiral troughs , which recent analysis of SHARAD ice penetrating radar has shown are a result of roughly perpendicular katabatic winds that spiral due to the Coriolis Effect . The seasonal frosting of some areas near the southern ice cap results in the formation of transparent 1 m thick slabs of dry ice above the ground . With the arrival of spring , sunlight warms the subsurface and pressure from subliming CO2 builds up under a slab , elevating and ultimately rupturing it . This leads to geyser-like eruptions of CO2 gas mixed with dark basaltic sand or dust . This process is rapid , observed happening in the space of a few days , weeks or months , a rate of change rather unusual in geology -- especially for Mars . The gas rushing underneath a slab to the site of a geyser carves a spider-like pattern of radial channels under the ice .", "qid": "503", "docid": "Martian_polar_ice_caps", "rank": 22, "score": 96192 }, { "content": "Title: 2010 Northern Hemisphere summer heat waves Content: The 2010 Northern Hemisphere summer heat waves included severe heat waves that impacted most of the United States , Kazakhstan , Mongolia , China , Hong Kong , North Africa and the European continent as a whole , along with parts of Canada , Russia , Indochina , South Korea and Japan during May , June , July , and August 2010 .

Around the summer solstice ( approximately 21 June in the Northern Hemisphere and 22 December in the Southern Hemisphere ) the sun is visible for the full 24 hours , given fair weather . The number of days per year with potential midnight sun increases the farther towards either pole one goes . Although approximately defined by the polar circles , in practice the midnight sun can be seen as much as 55 miles ( 90 km ) outside the polar circle , as described below , and the exact latitudes of the farthest reaches of midnight sun depend on topography and vary slightly year-to-year . Because there are no permanent human settlements south of the Antarctic Circle , apart from research stations , the countries and territories whose populations experience the midnight sun are limited to those crossed by the Arctic Circle : Canada ( Yukon , Northwest Territories , and Nunavut ) , Greenland , Iceland , Finland , Norway , Russia , Sweden , and the United States ( Alaska ) . A quarter of Finland 's territory lies north of the Arctic Circle , and at the country 's northernmost point the sun does not set at all for 60 days during summer . In Svalbard , Norway , the northernmost inhabited region of Europe , there is no sunset from approximately 19 April to 23 August . The extreme sites are the poles , where the sun can be continuously visible for half the year . North Pole has midnight sun for Least 6 months from late March to late September . The opposite phenomenon , polar night , occurs in winter , when the sun stays below the horizon throughout the day . Since the axial tilt of the Earth is considerable ( approximately 23 degrees 27 minutes ) , the sun does not set at high latitudes in local summer . The duration of sunlight increases from one day during the summer solstice at the polar circle , to several weeks only 100 km closer to the pole , to six months at the poles . At extreme latitudes , the midnight sun is usually referred to as polar day . At the poles themselves , the sun rises and sets only once each year . During the six months that the sun is above the horizon , it spends the days continuously moving in circles around the observer , gradually spiralling higher and reaching its highest circuit of the sky at the summer solstice . Because of atmospheric refraction , and also because the sun is a disc rather than a point , the midnight sun may be experienced at latitudes slightly below the polar circle , though not exceeding one degree ( depending on local conditions ) . For example , Iceland is known for its midnight sun , even though most of it ( Grímsey is the exception ) is slightly south of the Arctic Circle . For the same reasons , the period of sunlight at the poles is slightly longer than six months . Even the northern extremities of Scotland ( and places at similar latitudes , such as St. Petersburg ) experience twilight throughout the night in the northern sky at around the summer solstice . Observers at heights appreciably above sea level can experience extended periods of midnight sun as a result of the `` dip '' of the horizon viewed from altitude .", "qid": "503", "docid": "Midnight_sun", "rank": 25, "score": 94484 }, { "content": "Title: Solar eclipse of January 4, 1639 Content: A partial solar eclipse occurred on January 4 , 1639 during winter in Asia 's Siberia in the Samoyed lands .

These strong radar echoes are associated with the extremely cold temperatures that occur above continental Antarctica during the summer . Rocket and radar measurements indicate that a partial reflection from a multitude of ion layers and constructive interference causes at least some of the PMSE . Generally PMSE exhibits dramatic variations in height and intensity as well as large variations in Doppler shift . PMSE exhibit strong signal power enhancements of scattering cross section at VHF radar frequencies in the range 50 MHz to 250 MHz , at times even to over 1 GHz , that occur in summer at high latitudes . The peak PMSE height is slightly below the summer mesopause temperature minimum at 88 km , and above the noctilucent cloud ( NLC ) and/or polar mesospheric cloud ( PMC ) layer at 83 -- 84 km . The usual instrument for observing PMSE is the a VHF Mesosphere-Stratosphere-Troposphere ( MST ) radar , although LIDARs and sounding rockets have also been used . PMSE is believed to be caused by structural irregularities in the ionospheric electron density at lower altitudes . The exact cause of PMSE is not yet known , although theorists have proposed steep electron density gradients , heavy positive ions , dressed aerosols , gravity waves and turbulence as possible explanations .

In the Northern Hemisphere this is the December solstice and in the Southern Hemisphere this is the June solstice . The axial tilt of Earth and gyroscopic effects of its daily rotation mean that the two opposite points in the sky to which the Earth 's axis of rotation points ( axial precession ) change very slowly ( making a complete circle approximately every 26,000 years ) . As the Earth follows its orbit around the Sun , the polar hemisphere that faced away from the Sun , experiencing winter , will , in half a year , face towards the Sun and experience summer . This is because the two hemispheres face opposite directions along Earth 's axis , and so as one polar hemisphere experiences winter , the other experiences summer . More evident from high latitudes , a hemisphere 's winter solstice occurs on the day with the shortest period of daylight and longest night of the year , when the sun 's daily maximum elevation in the sky is at its lowest . Although the winter solstice itself lasts only a moment in time , the term sometimes refers to the day on which it occurs . Other names are `` midwinter '' , the `` extreme of winter '' ( Dongzhi ) , or the `` shortest day '' . In some cultures it is seen as the middle of winter , while in others it is seen as the beginning of winter . In meteorology , winter in the Northern Hemisphere spans the entire period of December through February . The seasonal significance of the winter solstice is in the reversal of the gradual lengthening of nights and shortening hours of daylight during the day . The earliest sunset and latest sunrise dates differ from winter solstice , however , and these depend on latitude , due to the variation in the solar day throughout the year caused by the Earth 's elliptical orbit ( see earliest and latest sunrise and sunset ) .

The solar wind ionizes gas molecules in the upper atmosphere to such high energy that some of them reach escape velocity and pour into space . A considerable percentage of these ions remain bound inside Earth 's magnetic field , where they form part of the radiation belts . The term was coined in 1968 in a pair of articles by Banks and Holzer and by Ian Axford . Since the process by which the ionospheric plasma flows away from the Earth along magnetic field lines is similar to the flow of solar plasma away from the sun 's corona ( the solar wind ) , Axford suggested the term `` polar wind . '' The idea for the polar wind originated with the desire to solve the paradox of the terrestrial helium budget . This paradox consists of the fact that helium in the Earth 's atmosphere seems to be produced ( via radioactive decay of uranium and thorium ) faster than it is lost by escaping from the upper atmosphere . The realization that some helium could be ionized , and therefore escape the earth along open magnetic field lines near the magnetic poles ( the ` polar wind ' ) , is one possible solution to the paradox .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions . They were preserved so well by quick freezing , which is taken as evidence of a rapid onset of a global blizzard or similar event . Interspersed with the analytical parts of the book are a series of interlinked short fictional scenarios , written in italics , describing what might transpire today if a destabilization of the North Atlantic Current were to occur .

Cold air subsides at the poles creating the high pressure , forcing an equatorward outflow of air ; that outflow is then deflected westward by the Coriolis effect . Unlike the westerlies in the middle latitudes , the polar easterlies are often weak and irregular . These prevailing winds blow from the polar easterlies are one of the five primary wind zones , known as wind belts , that make up our atmosphere 's circulatory system . This particular belt of wind begins at approximately 60 degrees north and south latitude and reaches to the poles . When air moves near the poles , cold temperatures shrink the air . This promotes air from warmer latitudes to flow into the area , causing a polar high-pressure zone . Air from this high-pressure zone then rushes toward the low-pressure zone surrounding the sub-polar region . This flow of air is altered by the Earth 's rotation and deflected west , hence the name between high - and low-pressure zones , its path is deflected -- as we saw with the polar easterlies -- thanks to the rotation of the Earth . All of this unequal heat , rushing air and spinning Earth combine to form global currents such as the polar easterlies . Another example of the phenomenon would be the trade winds , which reach from where the doldrums ( the area that gets the biggest blast of heat from the sun ) leave off at about 5 degrees north and south latitude to as far as 30 degrees north and south . They are caused by air moving into the area from the subtropics to fill the void left by the doldrums ' rising air . The trade winds blow steadily westward out of the northeast in the Northern Hemisphere and out of the southeast in the Southern Hemisphere .

It has been found that carbon dioxide from the burning of coal , natural gas , and oil for electricity and heat is the largest single source of global greenhouse gas emissions . For years , governments and corporations have been attempting to balance out their emissions by participating in carbon-offsetting -- the practice in which they invest in renewable energy to compensate for the global-warming pollution that they produce . Despite these efforts the results are still far off and we continue to see growth in CO2 concentration . Now , a growing number of individuals are trying to make a reduction in the amount of CO2 that is being produced by participating in low carbon dieting . This small adjustment in household CO2 production has the potential to reduce emissions much more quickly than other kinds of changes and it deserves explicit consideration as part of climate policy .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years .

Climate engineering is an umbrella term for measures that mainly fall into two types : carbon dioxide removal and solar radiation management . Carbon dioxide removal addresses the cause of global warming by removing one of the greenhouse gases ( carbon dioxide ) from the atmosphere . Solar radiation management attempts to offset effects of greenhouse gases by causing the Earth to absorb less solar radiation . Climate engineering approaches are sometimes viewed as additional potential options for limiting global warming , alongside mitigation and adaptation . There is substantial agreement among scientists that climate engineering can not substitute for climate change mitigation . Some approaches might be used as accompanying measures to sharp cuts in greenhouse gas emissions . Given that all types of measures for addressing climate change have economic , political , or physical limitations , some climate engineering approaches might eventually be used as part of an ensemble of measures . Research on costs , benefits , and various types of risks of most climate engineering approaches is at an early stage and their understanding needs to improve to judge their adequacy and feasibility . Almost all research into solar radiation management has consisted of computer modelling or laboratory tests , and an attempt to move to outdoor experimentation was controversial . Some carbon dioxide removal practices , such as planting of trees and bio-energy with carbon capture and storage projects , are underway . Their scalability to effectively affect global climate is , however , debated . Ocean iron fertilization has been given small-scale research trials , sparking substantial controversy . Most experts and major reports advise against relying on climate engineering techniques as a simple solution to global warming , in part due to the large uncertainties over effectiveness and side effects . However , most experts also argue that the risks of such interventions must be seen in the context of risks of dangerous global warming . Interventions at large scale may run a greater risk of disrupting natural systems resulting in a dilemma that those approaches that could prove highly ( cost - ) effective in addressing extreme climate risk , might themselves cause substantial risk . Some have suggested that the concept of engineering the climate presents a so-called `` moral hazard '' because it could reduce political and public pressure for emissions reduction , which could exacerbate overall climate risks ; others assert that the threat of climate engineering could spur emissions cuts .

The Earth is much cooler and so radiates heat back away from itself at much longer wavelengths , mostly in the infrared range . The idealized greenhouse model is based on the fact that certain gases in the Earth 's atmosphere , including carbon dioxide and water vapour , are transparent to the high-frequency , high-energy solar radiation , but are much more opaque to the lower frequency infrared radiation leaving the surface of the earth . Thus heat is easily let in , but is partially trapped by these gases as it tries to leave . Rather than get hotter and hotter , Kirchhoff 's law of thermal radiation says that the gases of the atmosphere also have to re-emit the infrared energy that they absorb , and they do so , also at long infrared wavelengths , both upwards into space as well as downwards back towards the Earth 's surface . In the long-term , thermal equilibrium is reached when all the heat energy arriving on the planet is leaving again at the same rate . In this idealized model , the greenhouse gases cause the surface of the planet to be warmer than it would be without them , in order for the required amount of heat energy finally to be radiated out into space from the top of the atmosphere . The greenhouse effect can be illustrated with an idealized planet . This is a common `` textbook model '' : the planet will have a constant surface temperature Ts and an atmosphere with constant temperature Ta . For diagrammatic clarity , a gap can be depicted between the atmosphere and the surface . Alternatively , Ts could be interpreted as a temperature representative of the surface and the lower atmosphere , and Ta could be interpreted as the temperature of the upper atmosphere .

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction .

Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) .

These can include or be affected by temperature , aridity , resource availability , habitat requirements , enemies , soil characteristics , competitors , and pollinators .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change .

A low carbon diet is a way of reducing impact by choosing food that causes much less pollution . Trees : Protecting forests and planting new trees contributes to the absorption of carbon dioxide from the air . There are many opportunities to plant trees in the yard , along roads , in parks , and in public gardens . In addition , some charities plant fast-growing trees -- for as little as $ US0 .10 per tree -- to help people in tropical developing countries restore the productivity of their lands . Conversely , clearing old-growth forests adds to the carbon in the atmosphere , so buying non-old-growth paper is good for the climate as well as the forest .

Energy Star products use less energy . Travel : In the United States , perception towards climate change influenced people to change their travel lifestyle . More than a third of Americans have changed their travel habits in 2008 , versus only 14 % in 2007 . Cars : Purchasing a vehicle which gets high gas mileage helps to reduce emissions of carbon dioxide . Flying : Avoiding air travel and particularly frequent flyer programs has a high benefit because the convenience makes frequent , long distance travel easy , and high-altitude emissions are more potent for the climate than the same emissions made at ground level . Walking and running are among the least environmentally harmful modes of transportation , followed by the bicycle .

These methods of energy production emit no greenhouse gases once they are up and running . Carbon offsets : The principle of carbon offset is thus : one decides that they do n't want to be responsible for accelerating climate change , and they 've already made efforts to reduce their carbon dioxide emissions , so they decide to pay someone else to further reduce their net emissions by planting trees or by taking up low-carbon technologies . Every unit of carbon that is absorbed by trees -- or not emitted due to your funding of renewable energy deployment -- offsets the emissions from their fossil fuel use . In many cases , funding of renewable energy , energy efficiency , or tree planting -- particularly in developing nations -- can be a relatively cheap way of making an individual `` carbon neutral '' .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation .

For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph .

If we understand governance as the creation of `` conditions for ordered rule and collective action '' then , given the fact that the reduction of carbon emissions will require concerted collective action , it follows that the governance of carbon will be of paramount concern . We have seen numerous international conferences over the past 20 years tasked with finding a way of facilitating this , and while international agreements have been infamously difficult to reach , action at the national level has been much more effective . In the UK , the Climate Change Act 2008 committed the government to meeting significant carbon reduction targets . In England , these carbon emissions are governed using numerous different instruments , which involve a variety of actors . While it has been argued by authors like Rhodes that there has been a `` hollowing out '' of the nation state , and that governments have lost their capabilities to govern to a variety of non-state actors and the European Union , the case of carbon governance in England actually runs counter to this . The government body responsible for the task , the Department of Energy and Climate Change ( DECC ) , is the `` main external dynamic '' behind governing actions in this area , and `` rather than hollowing out ( there has actually been a strengthening of ) central co-ordination '' . The department may rely on other bodies to deliver its desired outcomes , but it is still ultimately responsible for the imposition of the rules and regulations that `` steer ( carbon ) governmental action at the national level '' . It is therefore evident that carbon governance in England is hierarchical in nature , in that `` legislative decisions and executive decisions '' are the main dynamic behind carbon governance action . This does not deny the existence of a network of bodies around DECC who are part of the process , but they are supplementary actors who are steered by central decisions .

Future effects of climate change will vary depending on climate change policies and social development . The two main policies to address climate change are reducing human greenhouse gas emissions ( climate change mitigation ) and adapting to the impacts of climate change . Geoengineering is another policy option . Near-term climate change policies could significantly affect long-term climate change impacts . Stringent mitigation policies might be able to limit global warming ( in 2100 ) to around 2 ° C or below , relative to pre-industrial levels .

Although climate sensitivity is usually used in the context of radiative forcing by carbon dioxide ( CO2 ) , it is thought of as a general property of the climate system : the change in surface air temperature ( ΔTs ) following a unit change in radiative forcing ( RF ) , and thus is expressed in units of ° C / ( W/m2 ) . For this to be useful , the measure must be independent of the nature of the forcing ( e.g. from greenhouse gases or solar variation ) ; to first order this is indeed found to be so . The climate sensitivity specifically due to is often expressed as the temperature change in ° C associated with a doubling of the concentration of carbon dioxide in Earth 's atmosphere . For coupled atmosphere-ocean global climate models ( e.g. CMIP5 ) the climate sensitivity is an emergent property : it is not a model parameter , but rather a result of a combination of model physics and parameters . By contrast , simpler energy-balance models may have climate sensitivity as an explicit parameter . The terms represented in the equation relate radiative forcing ( RF ) to linear changes in global surface temperature change ( ΔTs ) via the climate sensitivity λ .

CDR is a different approach than removing CO2 from the stack emissions of large fossil fuel point sources , such as power stations . The latter reduces emission to the atmosphere but can not reduce the amount of carbon dioxide already in the atmosphere . As CDR removes carbon dioxide from the atmosphere , it creates negative emissions , offsetting emissions from small and dispersed point sources such as domestic heating systems , airplanes and vehicle exhausts . It is regarded by some as a form of climate engineering , while other commentators describe it as a form of carbon capture and storage or extreme mitigation .

Two main forms of downscaling technique exist . One form is dynamical downscaling , where output from the GCM is used to drive a regional , numerical model in higher spatial resolution , which therefore is able to simulate local conditions in greater detail . The other form is statistical downscaling , where a statistical relationship is established from observations between large scale variables , like atmospheric surface pressure , and a local variable , like the wind speed at a particular site . The relationship is then subsequently used on the GCM data to obtain the local variables from the GCM output . In 1997 , Wilby and Wigley divided downscaling into four categories : regression methods , weather pattern-based approaches , stochastic weather generators , which are all statistical downscaling methods , and limited-area modeling .

DGVMs use time series of climate data and , given constraints of latitude , topography , and soil characteristics , simulate monthly or daily dynamics of ecosystem processes . DGVMs are used most often to simulate the effects of future climate change on natural vegetation and its carbon and water cycles . DGVMs generally combine biogeochemistry , biogeography , and disturbance submodels . Disturbance is often limited to wildfires , but in principle could include any of : forest/land management decisions , windthrow , insect damage , ozone damage etc. . DGVMs usually `` spin up '' their simulations from bare ground to `` equilibrium '' vegetation to establish realistic initial values for their various `` pools '' : carbon and nitrogen in live and dead vegetation , soil organic matter , etc. corresponding to a documented historical vegetation cover . DGVMs are usually run in a spatially distributed mode , with simulations carried out for thousands of `` cells '' , geographic points which are assumed to have homogeneous conditions within each cell . Simulations are carried out across a range of spatial scales , from global to landscape . Cells are usually arranged as lattice points ; the distance between adjacent lattice points may be as coarse as a few degrees of latitude or longitude , or as fine as 30 arc-seconds . Simulations of the conterminous United States in the first DGVM comparison exercise ( LPJ and MC1 ) called the VEMAP project in the 1990s used a lattice grain of one-half degree . Global simulations by the PIK group and collaborators using 6 different DGVMs ( HYBRID , IBIS , LPJ , SDGVM , TRIFFID , and VECODE ) used the same resolution as the general circulation model ( GCM ) that provided the climate data , 3.75 deg longitude x 2.5 deg latitude , a total of 1631 land grid cells . Sometimes lattice distances are specified in kilometers rather than angular measure , especially for finer grains , so a project like VEMAP is often referred to as 50 km grain . Several DGVMs appeared in the middle 1990s . The first was apparently IBIS ( Foley et al. , 1996 ) , VECODE ( Brovkin et al. , 1997 ) , followed by several others described below : Several DGVMs have been developed by various research groups around the world : LPJ - Germany , Sweden IBIS - Integrated Biosphere Simulator - U.S. MC1 - U.S. HYBRID - U.K. SDGVM - U.K. SEIB-DGVM - Japan TRIFFID - U.K. VECODE - Germany CLM-DVGM - U.S. Ecosystem Demography ( ED , ED2 ) The next generation of models - earth system models ( ex .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

This system is made up of earth 's water , ice , atmosphere , rocky crust , and all living things . Quantifying changes in these amounts is required to accurately model the Earth 's climate .

Energy is absorbed by the atmosphere , hydrosphere , and lithosphere , and , in a process informally described as Earth 's heat engine , the solar heating is redistributed through evaporation of surface water , convection , rainfall , winds , and ocean circulation . When the incoming solar energy is balanced by an equal flow of heat to space , the Earth is said to be in radiative equilibrium and under that condition , global temperatures will be stable . Disturbances of Earth 's radiative equilibrium , such as an increase of greenhouse gases , will change global temperatures in response . However , Earth 's energy balance and heat fluxes depend on many factors , such as atmospheric composition ( mainly aerosols and greenhouse gases ) , the albedo ( reflectivity ) of surface properties , cloud cover and vegetation and land use patterns . Changes in surface temperature due to Earth 's energy budget do not occur instantaneously , due to the inertia of the oceans and the cryosphere .

Circulation in the atmosphere and oceans is primarily driven by solar radiation and transports heat from the tropical regions to regions that receive less energy from the Sun. The water cycle also moves energy throughout the climate system. In addition, different chemical elements, necessary for life, are constantly recycled between the different components.

These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end . These periods are caused by variations in eccentricity , axial tilt , and precession of the Earth 's orbit . As part of the ongoing supercontinent cycle , plate tectonics will probably result in a supercontinent in 250 -- 350 million years . Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present . This will cause the atmosphere to become a `` moist greenhouse '' , resulting in a runaway evaporation of the oceans . As a likely consequence , plate tectonics will come to an end , and with them the entire carbon cycle . Following this event , in about 2 − 3 billion years , the planet 's magnetic dynamo may cease , causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere . Four billion years from now , the increase in the Earth 's surface temperature will cause a runaway greenhouse effect , heating the surface enough to melt it . By that point , all life on the Earth will be extinct . The most probable fate of the planet is absorption by the Sun in about 7.5 billion years , after the star has entered the red giant phase and expanded to cross the planet 's current orbit .", "qid": "508", "docid": "Future_of_Earth", "rank": 66, "score": 72594 }, { "content": "Title: The Weather of the Future Content: The Weather of the Future : Heat Waves , Extreme Storms , and Other Scenes From a Climate-Changed Planet ( ISBN 978-0-06-172688-0 ) is a 2010 book by climatologist Heidi Cullen .

Statistical models forecast the evolution of a tropical cyclone in a simpler manner , by extrapolating from historical datasets , and thus can be run quickly on platforms such as personal computers . Statistical-dynamical models use aspects of both types of forecasting . Four primary types of forecasts exist for tropical cyclones : track , intensity , storm surge , and rainfall . Dynamical models were not developed until the 1970s and the 1980s , with earlier efforts focused on the storm surge problem . Track models did not show forecast skill when compared to statistical models until the 1980s . Statistical-dynamical models were used from the 1970s into the 1990s . Early models use data from previous model runs while late models produce output after the official hurricane forecast has been sent . The use of consensus , ensemble , and superensemble forecasts lowers errors more than any individual forecast model . Both consensus and superensemble forecasts can use the guidance of global and regional models runs to improve the performance more than any of their respective components .

The procedure gets its name from its use of the Newtonian laws of the dynamics , or motion , of asteroids as they move around the Solar System . The procedure works by taking multiple position measurements to determine the gravitational deflection caused when two or more asteroids move past each other . The method relies on the fact that the large number of known asteroids means they will occasionally move past one another at very close distances . If at least one of the two interacting bodies is large enough , its gravitational influence on the other can reveal its mass . The accuracy of the determined mass is limited by the precision and timing of the appropriate astrometric observations being made to determine the gravitational deflection caused by a given interaction . Because the method relies on detecting the amount of gravitational deflection induced during an interaction , the procedure works best for objects which will produce a large deflection in their interactions with other objects . This means that the procedure works best for large objects , but it can also be effectively applied to objects which have repeated close interactions with each other such as when the two objects are in orbital resonance with one another . Regardless of the mass of the interacting objects , the amount of deflection will be greater if the objects approach nearer to each other and it will also be greater if the objects pass slowly , allowing more time for gravity to perturb the orbits of the two objects .

Though first attempted manually in the 1920s , it was not until the advent of the computer and computer simulation that computation time was reduced to less than the forecast period itself . ENIAC was used to create the first forecasts via computer in 1950 , and over the years more powerful computers have been used to increase the size of initial datasets as well as include more complicated versions of the equations of motion . The development of global forecasting models led to the first climate models . The development of limited area ( regional ) models facilitated advances in forecasting the tracks of tropical cyclone as well as air quality in the 1970s and 1980s . Because the output of forecast models based on atmospheric dynamics requires corrections near ground level , model output statistics ( MOS ) were developed in the 1970s and 1980s for individual forecast points ( locations ) . The MOS apply statistical techniques to post-process the output of dynamical models with the most recent surface observations and the forecast point 's climatology . This technique can correct for model resolution as well as model biases . Even with the increasing power of supercomputers , the forecast skill of numerical weather models only extends to about two weeks into the future , since the density and quality of observations -- together with the chaotic nature of the partial differential equations used to calculate the forecast -- introduce errors which double every five days .

Thus disturbances emanating from the western Pacific Ocean ( such as El Niño ) may propagate across the basin on time scales of weeks compared to years for corresponding basin-wide propagation at higher latitudes . The significance of shorter dynamic times scales near the equator is that they are similar to those of highly energetic atmospheric modes . This similarity allows the formation of coupled modes between the ocean and the atmosphere . TOGA was instrumental in developing a comprehensive observing system for the equatorial Pacific Ocean and laid important groundwork for ENSO prediction , data assimilation and understanding of air-sea interaction .", "qid": "508", "docid": "Tropical_Ocean_Global_Atmosphere_program", "rank": 98, "score": 69757 }, { "content": "Title: Frozen Planet Content: Frozen Planet is a 2011 British nature documentary series , co-produced by the BBC and The Open University .

A first application of this concept of dynamical time was the definition of the ephemeris time scale ( ET ) . In the late 19th century it was suspected , and in the early 20th century it was established , that the rotation of the Earth ( i.e. the length of the day ) was both irregular on short time scales , and was slowing down on longer time scales . The suggestion was made , that observation of the position of the Moon , Sun and planets and comparison of the observations with their gravitational ephemerides would be a better way to determine a uniform time scale . A detailed proposal of this kind was published in 1948 and adopted by the IAU in 1952 ( see Ephemeris time - history ) . Using data from Newcomb 's Tables of the Sun ( based on the theory of the apparent motion of the Sun by Simon Newcomb , 1895 , as retrospectively used in the definition of ephemeris time ) , the SI second was defined in 1960 as : the fraction 1/31 ,556,925.9747 of the tropical year for 1900 January 0 at 12 hours ephemeris time . Caesium atomic clocks became operational in 1955 , and their use provided further confirmation that the rotation of the earth fluctuated randomly . This confirmed the unsuitability of the mean solar second of Universal Time as a precision measure of time interval . After three years of comparisons with lunar observations it was determined that the ephemeris second corresponded to 9,192,631,770 + / - 20 cycles of the caesium resonance . In 1967/8 the length of the SI second was redefined to be 9,192,631,770 cycles of the caesium resonance , equal to the previous measurement result for the ephemeris second ( see Ephemeris time - redefinition of the second ) . In 1976 , however , the IAU resolved that the theoretical basis for ephemeris time was wholly non-relativistic , and therefore , beginning in 1984 ephemeris time would be replaced by two further time scales with allowance for relativistic corrections . Their names , assigned in 1979 , emphasized their dynamical nature or origin , Barycentric Dynamical Time ( TDB ) and Terrestrial Dynamical Time ( TDT ) . Both were defined for continuity with ET and were based on what had become the standard SI second , which in turn had been derived from the measured second of ET . During the period 1991 -- 2006 , the TDB and TDT time scales were both redefined and replaced , owing to difficulties or inconsistencies in their original definitions . The current fundamental relativistic time scales are Geocentric Coordinate Time ( TCG ) and Barycentric Coordinate Time ( TCB ) ; both of these have rates that are based on the SI second in respective reference frames ( and hypothetically outside the relevant gravity well ) , but on account of relativistic effects , their rates would appear slightly faster when observed at the Earth 's surface , and therefore diverge from local earth-based time scales based on the SI second at the Earth 's surface . Therefore , the currently defined IAU time scales also include Terrestrial Time ( TT ) ( replacing TDT , and now defined as a re-scaling of TCG , chosen to give TT a rate that matches the SI second when observed at the Earth 's surface ) , and a redefined Barycentric Dynamical Time ( TDB ) , a re-scaling of TCB to give TDB a rate that matches the SI second at the Earth 's surface .", "qid": "508", "docid": "Dynamical_time_scale", "rank": 100, "score": 69624 } ]

This process is the fundamental cause of the greenhouse effect . The primary greenhouse gases in Earth 's atmosphere are water vapor , carbon dioxide , methane , nitrous oxide , and ozone . Without greenhouse gases , the average temperature of Earth 's surface would be about -18 ° C , rather than the present average of 15 ° C . In the Solar System , the atmospheres of Venus , Mars and Titan also contain gases that cause a greenhouse effect . Human activities since the beginning of the Industrial Revolution ( taken as the year 1750 ) have produced a 40 % increase in the atmospheric concentration of carbon dioxide , from 280 ppm in 1750 to 406 ppm in early 2017 . This increase has occurred despite the uptake of a large portion of the emissions by various natural `` sinks '' involved in the carbon cycle . Anthropogenic carbon dioxide emissions ( i.e. , emissions produced by human activities ) come from combustion of fossil fuels , principally coal , oil , and natural gas , along with deforestation , soil erosion and animal agriculture . It has been estimated that if greenhouse gas emissions continue at the present rate , Earth 's surface temperature could exceed historical values as early as 2047 , with potentially harmful effects on ecosystems , biodiversity and the livelihoods of people worldwide .

Despite these efforts the results are still far off and we continue to see growth in CO2 concentration . Now , a growing number of individuals are trying to make a reduction in the amount of CO2 that is being produced by participating in low carbon dieting . This small adjustment in household CO2 production has the potential to reduce emissions much more quickly than other kinds of changes and it deserves explicit consideration as part of climate policy .

It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide . A GWP is calculated over a specific time interval , commonly 20 , 100 , or 500 years . GWP is expressed as a factor of carbon dioxide ( whose GWP is standardized to 1 ) . In the Fifth Assessment Report of the Intergovernmental Panel on Climate Change , methane has a lifetime of 12.4 years and with climate-carbon feedbacks a global warming potential of 86 over 20 years and 34 over 100 years in response to emissions . User related choices such as the time horizon can greatly affect the numerical values obtained for carbon dioxide equivalents . For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph . Because the GWP of a greenhouse gas depends directly on its infrared spectrum , the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change .", "qid": "512", "docid": "Global_warming_potential", "rank": 22, "score": 136440 }, { "content": "Title: Contribution to global warming by Australia Content: Australia has one of the highest per capita emissions of carbon dioxide in the world , with 0.3 % of the world 's population it produces 1.8 % of the world 's greenhouse gasses .

Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming .

This is a derivative of Karl Marx 's concept of metabolic rift . In practical terms , increased commodity production demands that greater levels of carbon dioxide ( or CO2 ) be emitted into the biosphere via fossil fuel consumption . Carbon rift theory states that this ultimately disrupts the natural carbon cycle and that this `` rift '' has adverse effects on nearly every aspect of life . Many of the specifics regarding how this metabolic carbon rift interacts with capitalism are proposed by Brett Clark and Richard York in a 2005 article titled `` Carbon Metabolism : Global capitalism , climate change , and the biospheric rift '' in the journal Theory and Society . Researchers such as Jean P. Sapinski of the University of Oregon claim that , despite increased interest in closing the carbon rift , it is projected that as long as capitalism continues , there is little hope of reducing the rift . Both deforestation and the emission of greenhouse gases have been linked to increased atmospheric CO2 levels . Carbon rift theory states that these are the result of human production through capitalistic systems . There are proposed solutions to climate change such as geoengineering proposed in the December 2015 Paris Agreement . However , some argue that the capitalist mode of production is at fault for the emission of greenhouse gas and that solutions must be found to this issue before climate change itself can be addressed . Carbon rift theory , while rarely criticized directly , often indirectly receives criticism regarding the underlying causes of climate change and attributing the stated effects to alternative explanations for climate change , instead of as a result of human activity .

If a planet 's atmosphere contains radiatively active gases ( i.e. , greenhouse gases ) the atmosphere will radiate energy in all directions . Part of this radiation is directed towards the surface , warming it . The downward component of this radiation -- that is , the strength of the greenhouse effect -- will depend on the atmosphere 's temperature and on the amount of greenhouse gases that the atmosphere contains . On Earth , the atmosphere is warmed by absorption of infrared thermal radiation from the underlying surface ( heated by the sun ) , absorption of shorter wavelength radiant energy from the sun , and convective heat fluxes from the surface . Greenhouse gases in the atmosphere radiate energy , some of which is directed to the surface and lower atmosphere . The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect . Earth 's natural greenhouse effect is critical to supporting life . Human activities , primarily the burning of fossil fuels and clearing of forests , have intensified the natural greenhouse effect , causing global warming .

Climate engineering is an umbrella term for measures that mainly fall into two types : carbon dioxide removal and solar radiation management . Carbon dioxide removal addresses the cause of global warming by removing one of the greenhouse gases ( carbon dioxide ) from the atmosphere . Solar radiation management attempts to offset effects of greenhouse gases by causing the Earth to absorb less solar radiation . Climate engineering approaches are sometimes viewed as additional potential options for limiting global warming , alongside mitigation and adaptation . There is substantial agreement among scientists that climate engineering can not substitute for climate change mitigation . Some approaches might be used as accompanying measures to sharp cuts in greenhouse gas emissions . Given that all types of measures for addressing climate change have economic , political , or physical limitations , some climate engineering approaches might eventually be used as part of an ensemble of measures . Research on costs , benefits , and various types of risks of most climate engineering approaches is at an early stage and their understanding needs to improve to judge their adequacy and feasibility . Almost all research into solar radiation management has consisted of computer modelling or laboratory tests , and an attempt to move to outdoor experimentation was controversial . Some carbon dioxide removal practices , such as planting of trees and bio-energy with carbon capture and storage projects , are underway . Their scalability to effectively affect global climate is , however , debated . Ocean iron fertilization has been given small-scale research trials , sparking substantial controversy . Most experts and major reports advise against relying on climate engineering techniques as a simple solution to global warming , in part due to the large uncertainties over effectiveness and side effects . However , most experts also argue that the risks of such interventions must be seen in the context of risks of dangerous global warming . Interventions at large scale may run a greater risk of disrupting natural systems resulting in a dilemma that those approaches that could prove highly ( cost - ) effective in addressing extreme climate risk , might themselves cause substantial risk . Some have suggested that the concept of engineering the climate presents a so-called `` moral hazard '' because it could reduce political and public pressure for emissions reduction , which could exacerbate overall climate risks ; others assert that the threat of climate engineering could spur emissions cuts .

For example , in June 2012 , the UK coalition government announced the introduction of mandatory carbon reporting , requiring around 1,100 of the UK 's largest listed companies to report their greenhouse gas emissions every year . Deputy Prime Minister Nick Clegg confirmed that emission reporting rules would come into effect from April 2013 in his piece for The Guardian . Guidance for accounting for GHG emissions from organizations and emission reduction projects is provided by the World Resources Institute ( WRI ) and World Business Council for Sustainable Development ( WBCSD ) GHG Protocol . For national GHG inventories , guidance is provided by the Intergovernmental Panel on Climate Change ( IPCC ) methodology reports . The International Organization for Standardization ( ISO ) also provides some general standards for greenhouse gas emissions at organisation level ( ISO 14064 - 1 ) and greenhouse gas emissions at project level ( ISO 14064 - 2 ) .

One example of a Joint Implementation project resulting in an emission reduction unit , is the production of biogases by landfill sites . These gases consist of mainly methane which escapes to the atmosphere if it is not collected . The main reason for dealing with methane is that it has a 100-year global warming potential multiplier of 25 compared to carbon dioxide ( i.e. has 25 times the greenhouse potency ) .

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction . Climate changes is projected to affect individual organisms , populations , species distributions and ecosystem composition and function both directly ( ex . Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) .

These can include or be affected by temperature , aridity , resource availability , habitat requirements , enemies , soil characteristics , competitors , and pollinators .

The idealized greenhouse model is based on the fact that certain gases in the Earth 's atmosphere , including carbon dioxide and water vapour , are transparent to the high-frequency , high-energy solar radiation , but are much more opaque to the lower frequency infrared radiation leaving the surface of the earth . Thus heat is easily let in , but is partially trapped by these gases as it tries to leave .

In the long-term , thermal equilibrium is reached when all the heat energy arriving on the planet is leaving again at the same rate . In this idealized model , the greenhouse gases cause the surface of the planet to be warmer than it would be without them , in order for the required amount of heat energy finally to be radiated out into space from the top of the atmosphere .

From an economic policy perspective , an important distinction between biofuels and fossil fuels is that only the former is sustainable or renewable . Whereas we can continue to obtain energy from biofuels indefinitely in principle , the Earth 's reserves of fossil fuels was determined millions of years ago and is therefore fixed as far as our foreseeable future is concerned . The great variability in the ease of extraction of fossil fuels however makes its endgame scenario one of increasing prices over one or more centuries rather than of abrupt exhaustion .

However biofuels actively participate in the carbon cycle today by photosynthesizing carbon dioxide , unlike fossil fuels whose participation was long ago , and can therefore in principle bring atmospheric CO2 into an equilibrium not possible with the continued use of fossil fuel .

[ { "content": "Title: Milankovitch cycles Content: Milankovitch cycles describes the collective effects of changes in the Earth 's movements on its climate over thousands of years . The term is named after Serbian geophysicist and astronomer Milutin Milanković . In the 1920s , he theorized that variations in eccentricity , axial tilt , and precession of the Earth 's orbit resulted in cyclical variation in the solar radiation ( insolation ) reaching the Earth , and that this orbital forcing strongly influenced climatic patterns on Earth . The Earth 's orbit varies between nearly circular and mildly elliptical ( its eccentricity varies ) . When the orbit is more elongated , there is more variation in the distance between the Earth and the Sun , and in the amount of solar radiation , at different times in the year . In addition , the rotational tilt of the Earth ( its obliquity ) , which causes the seasons as the Earth revolves around the Sun , changes slightly . A greater tilt makes the seasons more extreme . Finally , the direction in the fixed stars pointed to by the Earth 's axis changes ( axial precession ) , while the Earth 's elliptical orbit around the Sun rotates ( apsidal precession ) . The combined effect of the two precessions is a cycle in which proximity to the Sun occurs during different astronomical seasons . If the Earth is closer to the Sun while the northern or southern hemisphere is tilted toward the Sun ( is in summer ) , then both effects work together to heat that hemisphere . If the Earth is further from the Sun during summer , the greater distance slightly reduces the heat of summer . Similar astronomical theories had been advanced in the 19th century by Joseph Adhemar , James Croll and others , but verification was difficult because there was no reliably dated evidence , and because it was unclear which periods were important . Now , materials on Earth that have been unchanged for millennia are being studied to indicate the history of Earth 's climate . A study of the chronology of Antarctic ice cores using oxygen-nitrogen ratios in air bubbles trapped in the ice , which appear to respond directly to the local insolation , concluded that the climatic response documented in the ice cores was driven by northern hemisphere insolation as proposed by the Milankovitch hypothesis . Analysis of deep-ocean cores and a seminal paper by Hays , Imbrie , and Shackleton provide additional validation of the Milankovitch hypothesis through physical artifacts .

Variations in the amount of incident solar energy drive changes in the climate of the Earth , and are recognised as a key factor in the timing of initiation and termination of glaciations .

These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end .

Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present .

The greenhouse effect is caused by greenhouse gases that absorb sunlight . Energy from the sun that reaches Earth is either retained or sent into space . Greenhouse gases in Earth 's atmosphere such as carbon dioxide , methane , and water vapor absorb energy which cause a blanketing effect that warms the earth . Aerosols such as black carbon also catalyze the warming effect as they are unreflective and absorb energy from the sun supplementing greenhouse gases in the warming effect .

In temperate and polar regions , the seasons are marked by changes in the intensity of sunlight that reaches the Earth 's surface , variations of which may cause animals to go into hibernation or to migrate , and plants to be dormant . During May , June , and July , the northern hemisphere is exposed to more direct sunlight because the hemisphere faces the sun . The same is true of the southern hemisphere in November , December , and January . It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux . However , due to seasonal lag , June , July , and August are the hottest months in the northern hemisphere and December , January , and February are the hottest months in the southern hemisphere . In temperate and subpolar regions , four calendar-based seasons are generally recognized : spring , autumn or fall , and winter . Ecologists often use a six-season model for temperate climate regions : prevernal , vernal , estival , serotinal , autumnal , and hibernal .

In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics .

Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years .

Due to the Earth 's axial tilt , the course of a year sees the passing of the seasons , marked by changes in weather , the hours of daylight , and , consequently , vegetation and soil fertility . In temperate and subpolar regions around the globe , four seasons are generally recognized : spring , summer , autumn and winter . In tropical and subtropical regions several geographical sectors do not present defined seasons ; but in the seasonal tropics , the annual wet and dry seasons are recognized and tracked . A calendar year is an approximation of the number of days of the Earth 's orbital period as counted in a given calendar . The Gregorian , or modern , calendar , presents its calendar year to be either a common year of 365 days or a leap year of 366 days , as do the Julian calendars ; see below . For the Gregorian calendar the average length of the calendar year ( the mean year ) across the complete leap cycle of 400 years is 365.2425 days . The ISO standard ISO 80000-3 , Annex C , supports the symbol `` a '' ( for Latin annus ) to represent a year of either 365 or 366 days . In English , the abbreviations `` y '' and `` yr '' are commonly used . In astronomy , the Julian year is a unit of time ; it is defined as 365.25 days of exactly seconds ( SI base unit ) , totalling exactly seconds in the Julian astronomical year . The word `` year '' is also used for periods loosely associated with , but not identical to , the calendar or astronomical year , such as the seasonal year , the fiscal year , the academic year , etc. .

In the time since the industrial revolution the climate has increasingly been affected by human activities that are causing global warming and climate change.The climate system receives nearly all of its energy from the sun. The climate system also radiates energy to outer space. The balance of incoming and outgoing energy, and the passage of the energy through the climate system, determines Earth's energy budget. When the incoming energy is greater than the outgoing energy, earth's energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and earth experiences cooling. The energy moving through Earth's climate system finds expression in weather, varying on geographic scales and time. Long-term averages and variability of weather in a region constitute the region's climate. Such changes can be the result of \"internal variability\", when natural processes inherent to the various parts of the climate system alter the distribution of energy. Examples include variability in ocean basins such as the Pacific decadal oscillation and Atlantic multidecadal oscillation. Climate variability can also result from external forcing, when events outside of the climate system's components nonetheless produce changes within the system.

Much of this energy is lost when the earth re-radiates it back into outer space , and the rest of the energy is distributed throughout the five components of Earth 's climate system . This system is made up of earth 's water , ice , atmosphere , rocky crust , and all living things . Quantifying changes in these amounts is required to accurately model the Earth 's climate . Received radiation is unevenly distributed over the planet , because the Sun heats equatorial regions more than polar regions . Energy is absorbed by the atmosphere , hydrosphere , and lithosphere , and , in a process informally described as Earth 's heat engine , the solar heating is redistributed through evaporation of surface water , convection , rainfall , winds , and ocean circulation . When the incoming solar energy is balanced by an equal flow of heat to space , the Earth is said to be in radiative equilibrium and under that condition , global temperatures will be stable . Disturbances of Earth 's radiative equilibrium , such as an increase of greenhouse gases , will change global temperatures in response . However , Earth 's energy balance and heat fluxes depend on many factors , such as atmospheric composition ( mainly aerosols and greenhouse gases ) , the albedo ( reflectivity ) of surface properties , cloud cover and vegetation and land use patterns . Changes in surface temperature due to Earth 's energy budget do not occur instantaneously , due to the inertia of the oceans and the cryosphere . The net heat flux is buffered primarily by becoming part of the ocean 's heat content , until a new equilibrium state is established between radiative forcings and the climate response .", "qid": "516", "docid": "Earth's_energy_budget", "rank": 49, "score": 104757 }, { "content": "Title: Orbiting Solar Observatory Content: The Orbiting Solar Observatory ( abbreviated OSO ) Program was the name of a series of American space telescopes primarily intended to study the Sun , though they also included important non-solar experiments . Eight were launched successfully into Low Earth orbit by NASA between 1962 and 1975 using Delta rockets . Their primary mission was to observe an 11-year sun spot cycle in UV and X-ray spectra . The initial seven ( OSO 1 -- 7 ) were built by Ball Aerospace , then known as Ball Brothers Research Corporation ( BBRC ) , in Boulder Colorado . OSO 8 was built by Hughes Space and Communications Company , in Culver City , California . The basic design of the entire series featured a rotating section , the `` Wheel , '' to provide gyroscopic stability . A second section , the `` Sail , '' was driven electrically against the Wheel 's rotation , and stabilized to point at the Sun . The Sail carried pointed solar instruments , and also the array of solar photovoltaic cells which powered the spacecraft . The critical bearing between the Wheel and the Sail was a major feature of the design , as it had to operate smoothly for months in the hard vacuum of space without normal lubrication . It also carried both the power from the Sail and the data from the pointed solar instruments to the Wheel , where most of the spacecraft functions were located . Additional science instruments could also be located in the Wheel , generally looking out on a rotating radius vector which scanned the sky , and also across the Sun , every few seconds . OSO B suffered an incident during integration and checkout activities on 14 April 1964 . The satellite was inside the Spin Test Facility at Cape Canaveral attached to the third stage of its Delta C booster when a technician accidentally ignited the booster through static electricity . The third-stage motor activated , launched itself and the satellite into the roof , and ricocheted into a corner of the facility until burning out . Three technicians were burned to death . The satellite , although damaged , was able to be repaired using a combination of prototype parts , spare flight parts and new components . It was launched ten months later on 3 February 1965 and was designated OSO 2 on orbit . OSO C never made it to orbit . Liftoff took place on 25 August 1965 and all went well through the second stage burn . During the coasting phase prior to third stage separation , its rocket motor ignited prematurely . This registered on ground readouts as an attitude disturbance followed by loss of second stage telemetry , and although the third stage managed to separate itself , it suffered from an 18 % drop in thrust . The OSO spacecraft could not attain orbital velocity and instead fell back into the atmosphere and burned up . The failure was suspected to have been caused by a modification to the igniter mechanism in the third stage after some minor technical difficulties experienced on the previous Delta C launch ( TIROS 10 on 2 Jul ) . The Advanced Orbiting Solar Observatory ( AOSO ) program was developed in the mid 1960s as a more advanced version of the OSO series . Conceived as a polar-orbiting satellite system , these spacecraft would continuously monitor the Sun and surrounding environment with detectors and electronic imaging ranging from x-rays to visual light . Due to budget constraints , the AOSO program was cancelled in 1965 . Instead , it was replaced by the OSO-I , OSO-J and OSO-K satellites .

He was the first to suggest that ice ages were controlled by astronomical forces in his 1842 book Revolutions of the Sea . The Earth 's orbit is elliptical , with the Sun at one focus ; lines drawn through the summer and winter solstice ; and the spring and autumn equinox ; intersect with the sun at right angles . The Earth is closest to the Sun ( perihelion ) near the northern hemisphere winter solstice . The earth moves faster through its orbit when closer to the sun . Hence , the period from the northern hemisphere 's autumn equinox to winter and spring is shorter by around seven days than the period from spring to summer to autumn ; the reverse is true in the southern hemisphere . Hence , northern hemisphere winter is shorter . Because of this , Adhemar reasoned that because the southern hemisphere had more hours of darkness in winter , it must be cooling , and attributed the Antarctic ice sheet to this . Adhemar knew of the 22,000 year cycle of precession of the equinoxes , and theorised that the ice ages occurred in this cycle . One immediate objection to the theory was that the total insolation during a year does not vary at all during the precessional cycle , only its seasonal distribution . Another was that the timing was wrong ; however this could not be tested by observations available at the time . Adhemar 's theory was further developed , first by James Croll and later by Milutin Milanković . Adhemar predicted the Antarctic ice sheet and theorised about its thickness by comparing the depths of the Arctic and circum-Antarctic oceans . Finding the Antarctic oceans deeper ( the measurements he used may not have been fully representative ) and attributing this to the gravitational attraction of the Antarctic ice sheet , he postulated a truly enormous ice sheet approximately 90 km thick .", "qid": "516", "docid": "Joseph_Adhémar", "rank": 58, "score": 103360 }, { "content": "Title: Solar cycle 7 Content: Solar cycle 7 was the seventh solar cycle since 1755 , when extensive recording of solar sunspot activity began .

Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically .

Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) .

For example , Jupiter has a sidereal period of 11.86 years while the main binary star Alpha Centauri AB has a period of about 79.91 years .

Such an orbit can place a satellite in constant sunlight and is useful for imaging , spy , and weather satellites . More technically , it is an orbit arranged in such a way that it precesses once a year . The surface illumination angle will be nearly the same every time that the satellite is overhead . This consistent lighting is a useful characteristic for satellites that image the Earth 's surface in visible or infrared wavelengths ( e.g. weather and spy satellites ) and for other remote sensing satellites ( e.g. those carrying ocean and atmospheric remote sensing instruments that require sunlight ) . For example , a satellite in sun-synchronous orbit might ascend across the equator twelve times a day each time at approximately 15:00 mean local time . This is achieved by having the osculating orbital plane precess ( rotate ) approximately one degree each day with respect to the celestial sphere , eastward , to keep pace with the Earth 's movement around the Sun . The uniformity of Sun angle is achieved by tuning the inclination to the altitude of the orbit ( see Technical details ) such that the extra mass near the equator causes the orbital plane of the spacecraft to precess with the desired rate : the plane of the orbit is not fixed in space relative to the distant stars , but rotates slowly about the Earth 's axis . Typical sun-synchronous orbits are about 600 -- 800 km in altitude , with periods in the 96 -- 100 minute range , and inclinations of around 98 ° ( i.e. slightly retrograde compared to the direction of Earth 's rotation : 0 ° represents an equatorial orbit and 90 ° represents a polar orbit ) . Special cases of the sun-synchronous orbit are the noon/midnight orbit , where the local mean solar time of passage for equatorial longitudes is around noon or midnight , and the dawn/dusk orbit , where the local mean solar time of passage for equatorial longitudes is around sunrise or sunset , so that the satellite rides the terminator between day and night . Riding the terminator is useful for active radar satellites as the satellites ' solar panels can always see the Sun , without being shadowed by the Earth . It is also useful for some satellites with passive instruments that need to limit the Sun 's influence on the measurements , as it is possible to always point the instruments towards the night side of the Earth . The dawn/dusk orbit has been used for solar observing scientific satellites such as Yohkoh , TRACE , Hinode and PROBA2 , affording them a nearly continuous view of the Sun . Sun-synchronous orbits can happen around other oblate planets , such as Mars .

The total sum of all solar fluctuations is referred to as solar variation . The collective effect of all solar variations within the Sun 's gravitational field is referred to as space weather . A major weather component is the solar wind , a stream of plasma released from the Sun 's upper atmosphere .

Potential tipping points have been identified in the physical climate system, in impacted ecosystems, and sometimes in both. For instance, feedback from the global carbon cycle is a driver for the transition between glacial and interglacial periods, with orbital forcing providing the initial trigger. Earth's geologic temperature record includes many more examples of geologically rapid transitions between different climate states.Climate tipping points are of particular interest in reference to concerns about global warming in the modern era. Possible tipping point behaviour has been identified for the global mean surface temperature by studying self-reinforcing feedbacks and the past behavior of Earth's climate system. Self-reinforcing feedbacks in the carbon cycle and planetary reflectivity could trigger a cascading set of tipping points that lead the world into a hothouse climate state.Large-scale components of the Earth system that may pass a tipping point have been referred to as tipping elements. Tipping elements are found in the Greenland and Antarctic ice sheets, possibly causing tens of meters of sea level rise. These tipping points are not always abrupt. For example, at some level of temperature rise the melt of a large part of the Greenland ice sheet and/or West Antarctic Ice Sheet will become inevitable; but the ice sheet itself may persist for many centuries.

The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect .

Two major dry fluctuations occurred; during the Younger Dryas and the short 8.2 kiloyear event. The African humid period ended 6,000–5,000 years ago during the Piora Oscillation cold period. While some evidence points to an end 5,500 years ago, in the Sahel, Arabia and East Africa the period appears to have taken place in several steps such as the 4.2 kiloyear event. The AHP led to a widespread settlement of the Sahara and the Arabian Deserts, and had a profound effect on African cultures, such as the birth of the Pharaonic civilization. They lived as hunter-gatherers until the agricultural revolution and domesticated cattle, goats and sheep. They left archeological sites and artifacts such as one of the oldest ships in the world, and rock paintings such as those in the Cave of Swimmers and in the Acacus Mountains. Earlier humid periods in Africa were postulated after the discovery of these rock paintings in now-inhospitable parts of the Sahara. When the period ended, humans gradually abandoned the desert in favour of regions with more secure water supplies, such as the Nile Valley and Mesopotamia, where they gave rise to early complex societies.", "qid": "516", "docid": "African_humid_period", "rank": 92, "score": 95934 }, { "content": "Title: Akatsuki (spacecraft) Content: , also known as the Venus Climate Orbiter ( VCO ) and Planet-C , is a Japanese ( JAXA ) space probe tasked to study the atmosphere of Venus .

Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional : the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that `` Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely '' the highest in at least the past 1,300 years . '' The curve shown in graphs of these reconstructions is widely known as the hockey stick graph because of the sharp increase in temperatures during the last century . As of 2010 this broad pattern was supported by more than two dozen reconstructions , using various statistical methods and combinations of proxy records , with variations in how flat the pre-20th-century `` shaft '' appears . Sparseness of proxy records results in considerable uncertainty for earlier periods . Individual proxy records , such as tree ring widths and densities used in dendroclimatology , are calibrated against the instrumental record for the period of overlap . Networks of such records are used to reconstruct past temperatures for regions : tree ring proxies have been used to reconstruct Northern Hemisphere extratropical temperatures ( within the tropics trees do not form rings ) but are confined to land areas and are scarce in the Southern Hemisphere which is largely ocean . Wider coverage is provided by multiproxy reconstructions , incorporating proxies such as lake sediments , ice cores and corals which are found in different regions , and using statistical methods to relate these sparser proxies to the greater numbers of tree ring records . The `` Composite Plus Scaling '' ( CPS ) method is widely used for large-scale multiproxy reconstructions of hemispheric or global average temperatures ; this is complemented by Climate Field Reconstruction ( CFR ) methods which show how climate patterns have developed over large spatial areas , making the reconstruction useful for investigating natural variability and long-term oscillations as well as for comparisons with patterns produced by climate models . During the 1,900 years before the 20th century , it is likely that the next warmest period was from 950 to 1100 , with peaks at different times in different regions . This has been called the Medieval Warm Period , and some evidence suggests widespread cooler conditions during a period around the 17th century known as the Little Ice Age .

Because of the precession of the equinoxes , the seasonal cycle does not remain exactly synchronized with the position of the Earth in its orbit around the Sun .

Neoglaciation has followed the hypsithermal or Holocene Climatic Optimum , the warmest point in the Earth 's climate during the current interglacial stage . The neoglaciation has no well-marked universal beginning : local conditions and ecological inertia affected the onset of detectably cooler ( and wetter ) conditions . Driven inexorably by the Milankovitch cycle , cooler summers in higher latitudes of North America , which would cease to completely melt the annual snowfall , were masked at first by the presence of the slowly disappearing continental ice sheets , which persisted long after the astronomically calculated moment of maximum summer warmth : `` the neoglaciation can be said to have begun when the cooling caught up with the warming '' , remarked E. C. Pielou .

These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end . These periods are caused by variations in eccentricity , axial tilt , and precession of the Earth 's orbit . As part of the ongoing supercontinent cycle , plate tectonics will probably result in a supercontinent in 250 -- 350 million years . Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present . This will cause the atmosphere to become a `` moist greenhouse '' , resulting in a runaway evaporation of the oceans . As a likely consequence , plate tectonics will come to an end , and with them the entire carbon cycle . Following this event , in about 2 − 3 billion years , the planet 's magnetic dynamo may cease , causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere . Four billion years from now , the increase in the Earth 's surface temperature will cause a runaway greenhouse effect , heating the surface enough to melt it .

It was produced by a National Research Council committee , chaired by Gerald North , at the request of Representative Sherwood Boehlert as chairman of the U.S. House of Representatives Committee on Science . These reconstructions had been dubbed `` hockey stick graphs '' after the 1999 reconstruction by Mann , Bradley and Hughes ( MBH99 ) , which used the methodology of their 1998 reconstruction covering 600 years ( MBH98 ) . A graph based on MBH99 was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , and became a focus of the global warming controversy over the 1997 Kyoto Protocol . It was disputed by various contrarians , and in the politicisation of this hockey stick controversy the New York Times of 14 February 2005 hailed a paper by businessman Stephen McIntyre and economist Ross McKitrick ( MM05 ) as undermining the scientific consensus behind the Kyoto agreement . On 23 June 2005 , Rep. Joe Barton , chairman of the House Committee on Energy and Commerce , with Ed Whitfield , Chairman of the Subcommittee on Oversight and Investigations , wrote joint letters referring to issues raised by the Wall Street Journal article , and demanding that Mann , Bradley and Hughes provide full records on their data and methods , finances and careers , information about grants provided to the institutions they had worked for , and the exact computer codes used to generate their results . Boehlert said this was a `` misguided and illegitimate investigation '' into something that should properly be under the jurisdiction of the Science Committee , and in November 2005 after Barton dismissed the offer of an independent investigation organised by the U.S. National Academy of Sciences , Boehlert requested the review , which became the North Report .

The generational planets are the outer planets Uranus , Neptune , Pluto , Sedna , and Quaoar . Uranus was discovered by amateur astronomer William Herschel on 13 March 1781 . Uranus exhibits the ideals of the 18th century , where people such as Benjamin Franklin endeavoured to use their inventive mind to move man into a more enlightened era . It has an orbit of 84 years , staying in each sign of the zodiac for approximately 7 years . Uranus is considered to be a higher octave of Mercury , which means that as people develop within their selves , their character and means of communication will exhibit more influences of the sign and house of Uranus . In essence , Uranus can be seen as a person 's higher self . Because it takes Uranus 84 years to travel through the zodiac , transiting Uranus just might conjoin the natal Uranus within a person 's lifetime . Neptune was discovered on 23 September 1846 . Neptune is a 19th-century planet in that it heralded in many of the varied assortment of Protestant religions , as well as spiritualism , took hold . Visionaries such as Edgar Cayce and Rudolf Steiner were born in the second half of the 19th century , and their psychic abilities are indicative of the Neptunian themes of this time . It has an orbit of 165 years , which is approximately twice the time of Uranus . Neptune is considered to be the higher octave of Venus because both planet 's are gaseous and both strive to achieve the higher ideals of mankind ; Venus through the adoption of beauty and Neptune through unconditional love . Because Neptune has such a long orbit , an individual may see transiting Neptune form an opposition to their natal Neptune . Pluto was discovered by Clyde W. Tombaugh on 18 February 1930 . When Pluto was first discovered , it was initially known as Planet X. Astronomers had been searching for another planet past Neptune , hoping to solve the dilemma of its rather irregular orbit . It is now known , however , that the perceived irregular orbit of Neptune was the result of a mathematical error because Pluto , being a planetoid smaller than our own Moon , was far too small to affect any type of gravitational pull on the gas giant . Pluto is very much a 20th-century planet and refers to the two world wars , and weapons of mass destruction , nuclear power , and a desire to totally control the world we live in . It is a planet that reveals to us the extremes we are capable of if we do not set necessary boundaries in our lives . This planet governs the compulsions in our life : those things we are compelled to do but know we should not , such as murder , rape , drug addiction , and even overeating if it is of such an extent that it threatens our health . Pluto is considered to be a higher octave of Mars , and this is evidenced by the fact that both planets co-rule Scorpio . Pluto , circling the Sun in 248 years , has a rather elliptical orbit , which means that it stays in the sign it rules , Scorpio , for a mere 9 years , and the sign of its fall , Taurus for 30 ! With this in mind , some astrologers believe that Pluto should rightfully rule Taurus , but for the time being it still rules Scorpio . As other trans-Neptunian object planets are discovered , however , this placement just might have to be reconsidered . Quaoar was discovered on 4 June 2002 and is considered to be a trans-Neptunian object . Although a planetoid , it is considered by many to be more of a planet than Pluto because its orbit is more circular in nature , being 286 years . When a person is around 71 years old , transiting Quaoar will form a square aspect to his natal placement . Since this is a recently discovered object , not much is yet known about its astrological significance and what part it plays in the universe . Sedna was discovered by a team using the Samuel Oschin telescope on 14 November 2003 and is a trans-Neptunian object . It has an orbit of 11,250 years , so stays in a sign for approximately a millennium .

Although Mars is smaller than the Earth , at 11 % of Earth 's mass , and 50 % farther from the Sun than the Earth , its climate has important similarities , such as the polar ice caps , seasonal changes and the observable presence of weather patterns . It has attracted sustained study from planetologists and climatologists . While Mars 's climate has similarities to Earth 's , including periodic ice ages , there are also important differences , such as much lower thermal inertia . Mars ' atmosphere has a scale height of approximately 11 km , 60 % greater than that on Earth . The climate is of considerable relevance to the question of whether life is or was present on the planet . The climate briefly received more interest in the news due to NASA measurements indicating increased sublimation of the south polar icecap leading to some popular press speculation that Mars was undergoing a parallel bout of global warming , although Mars ' average temperature has actually cooled in recent decades . Mars has been studied by Earth-based instruments since the 17th century but it is only since the exploration of Mars began in the mid-1960s that close-range observation has been possible . Flyby and orbital spacecraft have provided data from above , while direct measurements of atmospheric conditions have been provided by a number of landers and rovers . Advanced Earth orbital instruments today continue to provide some useful `` big picture '' observations of relatively large weather phenomena . The first Martian flyby mission was Mariner 4 which arrived in 1965 . That quick two-day pass ( July 14 -- 15 , 1965 ) was limited and crude in terms of its contribution to the state of knowledge of Martian climate . Later Mariner missions ( Mariner 6 , and Mariner 7 ) filled in some of the gaps in basic climate information . Data-based climate studies started in earnest with the Viking program in 1975 and continues with such probes as the Mars Reconnaissance Orbiter . This observational work has been complemented by a type of scientific computer simulation called the Mars general circulation model .

The cooling causes the pressure to drop , and the star or planet shrinks as a result . This compression , in turn , heats the core of the star/planet . This mechanism is evident on Jupiter and Saturn and on brown dwarfs whose central temperatures are not high enough to undergo nuclear fusion . It is estimated that Jupiter radiates more energy through this mechanism than it receives from the Sun , but Saturn might not . The latter process causes Jupiter to shrink at a rate of two centimetres each year . The mechanism was originally proposed by Kelvin and Helmholtz in the late 19th century to explain the source of energy of the Sun . By the mid-19th century , conservation of energy had been accepted , and one consequence of this law of physics is that the Sun must have some energy source to continue to shine . Because nuclear reactions were unknown , the main candidate for the source of solar energy was gravitational contraction .

Nearly all branches of natural science have contributed to the understanding of the main events of the Earth 's past . The age of Earth is approximately one-third of the age of the universe . An immense amount of geological change has occurred in that timespan , accompanied by the emergence of life and its subsequent evolution . Earth formed around 4.54 billion years ago by accretion from the solar nebula . Volcanic outgassing probably created the primordial atmosphere and then the ocean ; but the atmosphere contained almost no oxygen and so would have been toxic to most modern life including humans . Much of the Earth was molten because of frequent collisions with other bodies which led to extreme volcanism . A giant impact collision with a planet-sized body named Theia while Earth was in its earliest stage , also known as Early Earth , is thought to have been responsible for forming the Moon . Over time , the Earth cooled , causing the formation of a solid crust , and allowing liquid water to exist on the surface . The geological time scale ( GTS ) clock ( see graphic ) depicts the larger spans of time from the beginning of the Earth as well as a chronology of some definitive events of Earth history . The Hadean Eon represents time before the reliable ( fossil ) record of life beginning on Earth ; it began with the formation of the planet and ended at 4.0 billion years ago as defined by international convention . The Archean and Proterozoic eons follow ; they produced the abiogenesis of life on Earth and then the evolution of early life . The succeeding eon is the Phanerozoic , which is represented by its three component eras : the Palaeozoic ; the Mesozoic , which spanned the rise , reign , and climactic extinction of the huge dinosaurs ; and the Cenozoic , which presented the subsequent development of dominant mammals on Earth . Hominins , the earliest direct ancestors of the human clade , rose sometime during the latter part of the Miocene epoch ; the precise time marking the first hominins is broadly debated over a current range of 13 to 4 mya . The succeeding Quaternary period is the time of recognizable humans , i.e. , the genus Homo , but that period 's two million-year-plus term of the recent times is too small to be visible at the scale of the GTS graphic . ( Notes re the graphic : Ga means `` billion years '' ; Ma , `` million years '' . ) The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago , during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon . There are microbial mat fossils such as stromatolites found in 3.48 billion-year-old sandstone discovered in Western Australia . Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old metasedimentary rocks discovered in southwestern Greenland as well as `` remains of biotic life '' found in 4.1 billion-year-old rocks in Western Australia . According to one of the researchers , `` If life arose relatively quickly on Earth ... then it could be common in the universe . '' Living forms derived from photosynthesis appeared between 3.2 and 2.4 billion years ago and began enriching the atmosphere with oxygen . Life remained mostly small and microscopic until about 580 million years ago , when complex multicellular life arose , developed over time , and culminated in the Cambrian Explosion about 541 million years ago . This event drove a rapid diversification of life forms on Earth that produced most of the major phyla known today ; and it marked the end of the Proterozoic Eon and the beginning of the Cambrian Period of the Paleozoic Era . More than 99 percent of all species , amounting to over five billion species , that ever lived on Earth are estimated to be extinct . Estimates on the number of Earth 's current species range from 10 million to 14 million , of which about 1.2 million have been documented and over 86 percent have not yet been described . More recently , in May 2016 , scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described . Geological change has been a constant of Earth 's crust since the time of its formation , and biological change since the first appearance of life . Species continue to evolve , taking on new forms , splitting into daughter species or going extinct in the process of adapting or dying in response to ever-changing physical environments . The process of plate tectonics continues to play a dominant role in the shaping of Earth 's oceans and continents and the living species they harbor . Changes in the biosphere -- now dominated by human activity -- continue , in turn , to produce significant effects on the atmosphere and other systems of the Earth 's surface , such as the integrity of the ozone layer , the proliferation of greenhouse gases , the conditions of productive soils and clean air and water , and others .", "qid": "519", "docid": "History_of_Earth", "rank": 52, "score": 66491 }, { "content": "Title: Cooling, Kent Content: Cooling is a village and civil parish on the Hoo Peninsula , overlooking the North Kent Marshes , 6 miles north northwest of Rochester , England .

Small variations in the phase of pulsation led to the suggestion that the star was being orbited by a giant planet which caused the pulsations to be delayed due to the varying distance to the star caused by the reflex motion about the system 's centre-of-mass . Observations with the Spitzer Space Telescope failed to directly detect the planet , which put an upper limit on the mass of 5 -- 6 Jupiter masses . Investigation of a separate pulsation mode revealed timing variations in antiphase with the variations in the originally-analysed pulsation mode .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years . Global temperatures increased by 5 -- 8 ° C . The carbon dioxide was likely released in two pulses , the first lasting less than 2,000 years . Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon . Stratigraphic sections of rock from this period reveal numerous other changes . Fossil records for many organisms show major turnovers . For example , in the marine realm , a mass extinction of benthic foraminifera , a global expansion of subtropical dinoflagellates , and an appearance of excursion , planktic foraminifera and calcareous nanofossils all occurred during the beginning stages of PETM . On land , modern mammal orders ( including primates ) suddenly appear in Europe and in North America . Sediment deposition changed significantly at many outcrops and in many drill cores spanning this time interval . At least since 1997 , the Paleocene -- Eocene Thermal Maximum has become a focal point of considerable geoscience research because it probably provides the best past analog by which to understand impacts of global climate warming and of massive carbon input to the ocean and atmosphere , including ocean acidification .

These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century , with the instrumental temperature record by 2000 exceeding earlier temperatures . The term `` hockey stick graph '' was coined by the climatologist Jerry Mahlman , to describe the pattern shown by the ( MBH99 ) reconstruction , envisaging a graph that is relatively flat with a downward trend to 1900 as forming an ice hockey stick 's `` shaft '' followed by a sharp , steady increase corresponding to the `` blade '' portion . The reconstructions have featured in Intergovernmental Panel on Climate Change ( IPCC ) reports as evidence of global warming . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . Paleoclimatology dates back to the 19th century , and the concept of examining varves in lake beds and tree rings to track local climatic changes was suggested in the 1930s . In the 1960s , Hubert Lamb generalised from historical documents and temperature records of central England to propose a Medieval Warm Period from around 900 to 1300 , followed by Little Ice Age . This was the basis of a `` schematic diagram '' featured in the IPCC First Assessment Report of 1990 beside cautions that the medieval warming might not have been global . The use of indicators to get quantitative estimates of the temperature record of past centuries was developed , and by the late 1990s a number of competing teams of climatologists found indications that recent warming was exceptional . introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large scale reconstructions . Their study was featured in the IPCC Second Assessment Report of 1995 . In 1998 Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 with shading emphasising that uncertainties ( to two standard error limits ) were much greater in earlier centuries . independently produced a CPS reconstruction extending back for a thousand years , and ( MBH99 ) used the MBH98 methodology to extend their study back to 1000 . A version of the MBH99 graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , which also drew on Jones et al. 1998 and three other reconstructions to support the conclusion that , in the Northern Hemisphere , the 1990s was likely to have been the warmest decade and 1998 the warmest year during the past 1,000 years . The graph became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th century warmth was exceptional . In 2003 , as lobbying over the 1997 Kyoto Protocol intensified , a paper claiming greater medieval warmth was quickly dismissed by scientists in the Soon and Baliunas controversy . Later in 2003 , Stephen McIntyre and Ross McKitrick published disputing the data used in MBH98 paper . In 2004 Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 McIntyre and McKitrick published criticisms of the principal components analysis methodology as used in MBH98 and MBH99 . Their analysis was subsequently disputed by published papers including and which pointed to errors in the McIntyre and McKitrick methodology . Political disputes led to the formation of a panel of scientists convened by the National Research Council , their North Report in 2006 supported Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result . More than two dozen reconstructions , using various statistical methods and combinations of proxy records , support the broad consensus shown in the original 1998 hockey-stick graph , with variations in how flat the pre-20th century `` shaft '' appears . The 2007 IPCC Fourth Assessment Report cited 14 reconstructions , 10 of which covered 1,000 years or longer , to support its strengthened conclusion that it was likely that Northern Hemisphere temperatures during the 20th century were the highest in at least the past 1,300 years .

Due to the lack of solar heating and very strong radiative cooling from carbon dioxide , the mesosphere is the coldest region on Earth with temperatures as low as -100 ° C ( -148 ° F or 173 K ) . The altitude of the mesopause for many years was assumed to be at around 85 km ( 53 mi . ) , but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km .

It is due to a summer-to-winter circulation giving rise to upwelling at the summer pole and downwelling at the winter pole . Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause . In the mesosphere the summer-to-winter circulation is due to gravity wave dissipation , which deposits momentum against the mean east-west flow , resulting in a small north-south circulation . In recent years the mesopause has also been the focus of studies on global climate change associated with increases in CO2 . Unlike the troposphere , where greenhouse gases result in the atmosphere heating up , increased CO2 in the mesosphere acts to cool the atmosphere due to increased radiative emission . This results in a measurable effect - the mesopause should become cooler with increased CO2 .

Today , it includes M-dwarf late-type stars , at the threshold of L4 dwarf stars . They form a heterogeneous group which includes stars of very low mass and brown dwarfs . Together , they represent about 15 % of astronomical objects in the stellar neighbourhood of the Sun . The accretion model suggests that , considering their low mass and the small size of their proto-planetary disks , these stars could host a relatively abundant population of Earth-like planets ranging from Mercury-size to Earth-size .

This net decrease in the amount of carbonate ions available makes it more difficult for marine calcifying organisms , such as coral and some plankton , to form biogenic calcium carbonate , and such structures become vulnerable to dissolution . Ongoing acidification of the oceans threatens food chains connected with the oceans . As members of the InterAcademy Panel , 105 science academies have issued a statement on ocean acidification recommending that by 2050 , global emissions be reduced by at least 50 % compared to the 1990 level . While ongoing ocean acidification is anthropogenic in origin , it has occurred previously in Earth 's history . The most notable example is the Paleocene-Eocene Thermal Maximum ( PETM ) , which occurred approximately 56 million years ago . For reasons that are currently uncertain , massive amounts of carbon entered the ocean and atmosphere , and led to the dissolution of carbonate sediments in all ocean basins .

At the surface of the oceans towards the poles , seawater becomes cooler and more carbonic acid is formed as CO2 becomes more soluble . This is coupled to the ocean 's thermohaline circulation which transports dense surface water into the ocean 's interior ( see the entry on the solubility pump ) . Although the deep ocean contains much more dissolved inorganic carbon than the surface ocean , the concentration is only 15 % higher in the deep ocean as compared to the surface ocean due to the higher volume of the deep ocean . In upper ocean areas of high biological productivity , organisms convert reduced carbon to tissues , or carbonates to hard body parts such as shells and tests . These are , respectively , oxidized ( soft-tissue pump ) and redissolved ( carbonate pump ) at lower average levels of the ocean than those at which they formed , resulting in a downward flow of carbon ( see entry on the biological pump ) . The flux or absorption of carbon dioxide into the world 's oceans is influenced by the presence of widespread viruses within ocean water , that infect many species of bacteria . The resulting bacterial deaths spawn a sequence of events that lead to greatly enlarged respiration of carbon dioxide , enhancing the role of the oceans as a carbon sink . The balance of dissolved inorganic carbon ( DIC ) : dissolved organic carbon ( DOC ) : particle organic carbon is about 2000:38:1 . The CaCO3 counter pump increases the partial pressure of CO2 in the ocean , thus leading to higher outgasing of carbon dioxide . Higher ocean temperatures lead to stronger layering , thus less mixing and less capacity for thermohaline circulation to bring carbon into lower ocean layers . The weathering of silicate rock ( see carbonate-silicate cycle ) . Carbonic acid reacts with weathered rock to produce bicarbonate ions . The bicarbonate ions produced are carried to the ocean , where they are used to make marine carbonates . Unlike dissolved CO2 in equilibrium or tissues , which decay , weathering does not move the carbon into a reservoir from which it can readily return to the atmosphere . Much remains to be learned about the cycling of carbon in the deep ocean . For example , a recent discovery is that larvacean mucus houses ( commonly known as `` sinkers '' ) are created in such large numbers that they can deliver as much carbon to the deep ocean as has been previously detected by sediment traps . Because of their size and composition , these houses are rarely collected in such traps , so most biogeochemical analyses have erroneously ignored them . The amount of dissolved inorganic carbon in the ocean is significantly higher in the deep layer ( below 300 m depth ) .

The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) .

Land-use changes and fire , mainly associated with plantation development and logging ( deforestation and drainage ) , are reducing this carbon store and contributing to greenhouse gas ( GHG ) emissions . The problems that result from development of tropical peatland stem mainly from a lack of understanding of the complexities of this ecosystem and the fragility of the relationship between peat and forest . Once the forest is removed and the peat is drained , the surface peat oxidises and loses stored carbon rapidly to the atmosphere ( as carbon dioxide ) . This results in progressive loss of the peat surface , leading to local flooding and , due to the large areas involved , global climate change . Failure to account for such emissions results in underestimates of the rate of increase in atmospheric GHGs and the extent of human induced climate change .", "qid": "520", "docid": "Tropical_peat", "rank": 26, "score": 131554 }, { "content": "Title: Carbon dioxide removal Content: Carbon dioxide removal ( CDR ) methods refers to a number of technologies which reduce the levels of carbon dioxide in the atmosphere . Among such technologies are bio-energy with carbon capture and storage , biochar , direct air capture , ocean fertilization and enhanced weathering . CDR is a different approach than removing CO2 from the stack emissions of large fossil fuel point sources , such as power stations . The latter reduces emission to the atmosphere but can not reduce the amount of carbon dioxide already in the atmosphere . As CDR removes carbon dioxide from the atmosphere , it creates negative emissions , offsetting emissions from small and dispersed point sources such as domestic heating systems , airplanes and vehicle exhausts . It is regarded by some as a form of climate engineering , while other commentators describe it as a form of carbon capture and storage or extreme mitigation . Whether CDR would satisfy common definitions of `` climate engineering '' or `` geoengineering '' usually depends upon the scale on which it would be undertaken . The likely need for CDR has been publicly expressed by a range of individuals and organizations involved with climate change issues , including IPCC chief Rajendra Pachauri , the UNFCCC executive secretary Christiana Figueres , and the World Watch Institute . Institutions with major programs focusing on CDR include the Lenfest Center for Sustainable Energy at the Earth Institute , Columbia University , and the Climate Decision Making Center , an international collaboration operated out of Carnegie-Mellon University 's Department of Engineering and Public Policy . The mitigation effectiveness of air capture is limited by societal investment , land use , availability of geologic reservoirs , and leakage . The reservoirs are estimated to be sufficient to for storing at least 545 GtC . Storing 771 GtC would cause an 186 ppm atmospheric reduction .

The carbon neutrality concept may be extended to include other greenhouse gases ( GHG ) measured in terms of their carbon dioxide equivalence ( e ) -- the impact a GHG has on the atmosphere expressed in the equivalent amount of CO2 . The term `` climate neutral '' reflects the broader inclusiveness of other greenhouse gases in climate change , even if CO2 is the most abundant , encompassing other greenhouse gases regulated by the Kyoto Protocol , namely : methane ( CH4 ) , nitrous oxide ( N2O ) , hydrofluorocarbons ( HFC ) , perfluorocarbons ( PFC ) , and sulphur hexafluoride ( SF6 ) . Both terms are used interchangeably throughout this article . The best practice for organizations and individuals seeking carbon neutral status entails reducing and/or avoiding carbon emissions first so that only unavoidable emissions are offset . Carbon neutral status is commonly achieved in two ways : Balancing carbon dioxide released into the atmosphere from burning fossil fuels , with renewable energy that creates a similar amount of useful energy , so that the carbon emissions are compensated , or alternatively using only renewable energies that do n't produce any carbon dioxide ( also called a post-carbon economy ) . Carbon offsetting by paying others to remove or sequester 100 % of the carbon dioxide emitted from the atmosphere -- for example by planting trees -- or by funding ` carbon projects ' that should lead to the prevention of future greenhouse gas emissions , or by buying carbon credits to remove ( or ` retire ' ) them through carbon trading .

The transportation sector is a major source of greenhouse gas emissions ( GHGs ) in the United States . An estimated 30 percent of national GHGs are directly attributable to transportation -- and in some regions , the proportion is even higher . Transportation methods are the greatest contributing source of GHGs in the U.S. , accounting for 47 percent of the net increase in total U.S. emissions since 1990 . Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl , which can consume natural habitat and agricultural lands . By reducing transportation emissions globally , it is predicted that there will be significant positive effects on Earth 's air quality , acid rain , smog and climate change . The health impact of transport emissions is also of concern . A recent survey of the studies on the effect of traffic emissions on pregnancy outcomes has linked exposure to emissions to adverse effects on gestational duration and possibly also intrauterine growth . As listed above direct impacts such as noise and carbon monoxide emissions create direct and harmful effects on the environment , along with indirect impacts . The indirect impacts are often of higher consequence which leads to the misconception that it 's the opposite since it is frequently understood that initial effects cause the most damage . For example , particulates which are the outcome of incomplete combustion done by an internal combustion engine , are not linked with respiratory and cardiovascular problems since they contribute to other factors not only to that specific condition . Even though the environmental impacts are usually listed individually there are also cumulative impacts . The synergetic consequences of transport activities . They take into account of the varied effects of direct and indirect impacts on an ecosystem .

For this reason , Wright , Kemp , and Williams , have suggested to define the carbon footprint as : A measure of the total amount of carbon dioxide ( CO2 ) and methane ( CH4 ) emissions of a defined population , system or activity , considering all relevant sources , sinks and storage within the spatial and temporal boundary of the population , system or activity of interest . Calculated as carbon dioxide equivalent using the relevant 100-year global warming potential ( GWP100 ) .

For simplicity of reporting , it is often expressed in terms of the amount of carbon dioxide , or its equivalent of other GHGs , emitted . Most of the carbon footprint emissions for the average U.S. household come from `` indirect '' sources , i.e. fuel burned to produce goods far away from the final consumer . These are distinguished from emissions which come from burning fuel directly in one 's car or stove , commonly referred to as `` direct '' sources of the consumer 's carbon footprint . The concept name of the carbon footprint originates from ecological footprint , discussion , which was developed by Rees and Wackernagel in the 1990s which estimates the number of `` earths '' that would theoretically be required if everyone on the planet consumed resources at the same level as the person calculating their ecological footprint . However , given that ecological footprints are a measure of failure , Anindita Mitra ( CREA , Seattle ) chose the more easily calculated `` carbon footprint '' to easily measure use of carbon , as an indicator of unsustainable energy use . In 2007 , carbon footprint was used as a measure of carbon emissions to develop the energy plan for City of Lynnwood , Washington .

That charge , called a carbon price , is the amount that must be paid for the right to emit one tonne of CO2 into the atmosphere . Carbon pricing usually takes the form either of a carbon tax or a requirement to purchase permits to emit , generally known as cap-and-trade , but also called `` allowances '' . Carbon pricing solves the economic problem that , a known greenhouse gas , is what economics calls a negative externality -- a detrimental product that is not priced ( charged for ) by any market . As a consequence of not being priced , there is no market mechanism responsive to the costs of CO2 emitted . The standard economic solution to problems of this type , first proposed by Arthur Pigou in 1920 , is for the product - in this case , CO2 emissions - to be charged at a price equal to the monetary value of the damage caused by the emissions . This should result in the economically optimal ( efficient ) amount of CO2 emissions . Many practical concerns mar the theoretical simplicity of this picture : for example , the exact monetary damage caused by a tonne of CO2 is uncertain . The economics of carbon pricing is much the same for taxes and cap-and-trade . Both prices are efficient ; they have the same social cost and the same effect on profits if permits are auctioned . However , some economists argue that caps prevent non-price policies , such as renewable energy subsidies , from reducing carbon emissions , while carbon taxes do not . Others argue that an enforced cap is the only way to guarantee that carbon emissions will actually be reduced ; a carbon tax will not prevent those who can afford to do so from continuing to generate emissions . The choice of pricing approach , a tax or cap-and-trade , has been controversial . A carbon tax is generally favored on economic grounds for its simplicity and stability , while cap-and-trade is often favored on political grounds .

The aim is to prevent the release of large quantities of into the atmosphere ( from fossil fuel use in power generation and other industries ) . It is a potential means of mitigating the contribution of fossil fuel emissions to global warming and ocean acidification .

An integrated pilot-scale CCS power plant was to begin operating in September 2008 in the eastern German power plant Schwarze Pumpe run by utility Vattenfall , to test the technological feasibility and economic efficiency . CCS applied to a modern conventional power plant could reduce emissions to the atmosphere by approximately 80 -- 90 % compared to a plant without CCS . The IPCC estimates that the economic potential of CCS could be between 10 % and 55 % of the total carbon mitigation effort until year 2100 . Carbon dioxide can be captured out of air or fossil fuel power plant flue gas using adsorption ( or carbon scrubbing ) , membrane gas separation , or adsorption technologies . Amines are the leading carbon scrubbing technology . Capturing and compressing may increase the energy needs of a coal-fired CCS plant by 25 -- 40 % . These and other system costs are estimated to increase the cost per watt energy produced by 21 -- 91 % for fossil fuel power plants . Applying the technology to existing plants would be more expensive , especially if they are far from a sequestration site .

Through the transition to renewable energy sources , Germany has become the climate change policy leader and renewable energy leader in the European Union ( EU ) and in the world with ambitious climate change programs . The current goal of the German government was approved on 14 November 2016 in the German Climate Action Plan 2050 , which outlines measures by which Germany can meet its greenhouse gas emissions by 2050 . By 2050 , Germany wants to reduce their GHGs by 80 to 95 % and by 2030 they want to reduce it by 55 % , compared to the EU target of 40 % . In order to achieve these goals , a variety of strategies and policies are used rather than legislation . The four strategies the German government bases air pollution control on are laying down environmental quality standards , emission reduction requirements according to the best available technology , production regulations , and laying down emission ceilings . Through these strategies , policy instruments have been put in place that have contributed to the success of the significant air pollution reduction in Germany . These instruments include the Federal Emission Control Act and Implementing Ordinances , Technical Instructions on Air Quality Control ( TA Luft ) , Amendment to Ordinance on Small Firing Installations , Implementation of the directive on industrial emissions , and Transboundary air pollution control policy . The German Feed-in-Tariff policy introduced in 2000 led to the significant increase in renewable energy use and decreasing air pollution . They have been introduced in Germany to increase the use of renewables , such as wind power , biomass , hydropower , geothermal power , and photovoltaics , thereby reducing GHG emissions causing air pollution and combating climate change . The German government has been an agenda setter in international climate policy negotiations since the late 1980s . However , national and global climate policies have become a top priority since the conservative-social democratic government came into power in 2005 , pushing both European and international climate negotiations .

They help to address the problem of emitters of greenhouse gases not facing the full social cost of their actions . Carbon taxes can be a regressive tax , in that they may directly or indirectly affect low-income groups disproportionately . The regressive impact of carbon taxes could be addressed by using tax revenues to favour low-income groups . A number of countries have implemented carbon taxes or energy taxes that are related to carbon content . Most environmentally related taxes with implications for greenhouse gas emissions in OECD countries are levied on energy products and motor vehicles , rather than on emissions directly . Opposition to increased environmental regulation such as carbon taxes often centers on concerns that firms might relocate and/or people might lose their jobs . It has been argued , however , that carbon taxes are more efficient than direct regulation and may even lead to higher employment ( see footnotes ) . Many large users of carbon resources in electricity generation , such as the United States , Russia , and China , are resisting carbon taxation .", "qid": "520", "docid": "Carbon_tax", "rank": 72, "score": 115622 }, { "content": "Title: Flue-gas emissions from fossil-fuel combustion Content: Flue-gas emissions from fossil-fuel combustion refers to the combustion-product gas resulting from the burning of fossil fuels . Most fossil fuels are combusted with ambient air ( as differentiated from combustion with pure oxygen ) . Since ambient air contains about 79 volume percent gaseous nitrogen ( N2 ) , which is essentially non-combustible , the largest part of the flue gas from most fossil-fuel combustion is uncombusted nitrogen . Carbon dioxide , the next largest part of flue gas , can be as much as 10 − 25 volume percent or more of the flue gas . This is closely followed in volume by water vapor ( H2O ) created by the combustion of the hydrogen in the fuel with atmospheric oxygen . Much of the ` smoke ' seen pouring from flue gas stacks is this water vapor forming a cloud as it contacts cool air . A typical flue gas from the combustion of fossil fuels contains very small amounts of nitrogen oxides ( NOx ) , sulfur dioxide ( SO2 ) and particulate matter . The nitrogen oxides are derived from the nitrogen in the ambient air as well as from any nitrogen-containing compounds in the fossil fuel . The sulfur dioxide is derived from any sulfur-containing compounds in the fuels . The particulate matter is composed of very small particles of solid materials and very small liquid droplets which give flue gases their smoky appearance . The steam generators in large power plants and the process furnaces in large refineries , petrochemical and chemical plants , and incinerators burn considerable amounts of fossil fuels and therefore emit large amounts of flue gas to the ambient atmosphere . The table below presents the total amounts of flue gas typically generated by the burning of fossil fuels such as natural gas , fuel oil and coal . The data were obtained by stoichiometric calculations . It is of interest to note that the total amount of flue gas generated by coal combustion is only 10 percent higher than the flue gas generated by natural-gas combustion .

Signed in 1998 , the agreement sought to achieve an average of 140 g/km of CO2 by 2008 for new passenger vehicles sold by the association 's cars in Europe . This target represents a 25 % reduction from the 1995 level of 186 g/km and is equivalent to a fuel economy of 5.8 L/100 km or 5.25 L/100 km for petrol and diesel engines respectively . However , the average for the whole car market for 2008 was 153.7 g/km , so the target has not been achieved .

It plays a large part in the carbon cycle , since the equilibrium point of the carbonate-silicate cycle dictates the pace of carbon release from the lithosphere . The carbonate-silicate cycle involves several chemical reactions that occur in different environments . In the atmosphere , gaseous carbon dioxide ( CO2 ) dissolves in rainwater , forming natural carbonic acid ( H2CO3 ) . This weak acid weathers silicate rocks on continents , slowly dissolving the rock and releasing aqueous minerals through the chemical reaction CaSiO3 ( s ) ( wollastonite ) + 2CO2 ( g ) + H2O ( l ) → Ca + 2HCO ( aq ) ( bicarbonate ) + SiO2 ( aq ) ( dissolved silica ) . These dissolved minerals are eventually carried by water to the ocean , where they are used by living organisms such as foraminifera , radiolarians , coccolithopores , and diatoms to create shells of CaCO3 ( calcite ) or SiO2 ( opal ) through the reactions Ca2 + ( aq ) + 2HCO3 → CaCO3 ( s ) + CO2 ( g ) + H2O ( l ) ( for calcite precipitation ) and SiO2 ( aq ) → SiO2 ( s ) ( for opal precipitation ) . When these organisms die , many shells are remineralized but some shells fall all the way to the sea floor and are buried . The cycle is completed when the sea floor is subducted and carbonate minerals recombine with silicate minerals under temperatures above 300 ° C to reform calcium silicates and release gaseous CO2 through volcanism ( CaCO3 ( s ) + SiO2 ( s ) → CaSiO3 ( s ) + CO2 ( g ) ) . The carbonate-silicate cycle impacts the global carbon cycle , as carbon dioxide is removed from the Earth 's surface through the burial of weathered minerals in deep ocean sediments and returned to the atmosphere through metamorphism and volcanism . However , this process is far from being a closed loop . In Earth history generally the formation of carbonates significantly outpaces the formation of silicates , effectively removing carbon dioxide from the atmosphere . Because carbon dioxide is a potent greenhouse gas , the carbonate-silicate cycle is suspected to initiate ice ages by creating a negative feedback on the global temperature with a typical time scale of a few million years that is capable of countering water vapor and carbon dioxide short-term positive feedback on global temperature . The carbonate-silicate cycle equilibrium point is shifted on Venus due to surface temperatures above 300 ° C , which favor the formation of calcium silicates over weathering .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago .

Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon .

[ { "content": "Title: Local World Evolving Network Models Content: Evolving networks are dynamic networks which change in time . In each period t there are new nodes and edges that join the network while the old ones disappear . Such dynamic behaviour is characteristic for most real-world networks , regardless of their range - global or local . However , networks differ not only in their range but also in their topological structure . It is possible to distinguish : Random networks Free - scale networks Small - world networks Local -- world networks One of the main feature which allows to differentiate networks is their evolution process . In random networks points are added and removed from the network in a totally random way ( model of Erdős and Rényi ) . Evolution of free scale networks is based on the preferential attachment -- nodes connect to nodes that have already possessed a large number of links . In result hubs ( nodes that have the largest number of edges ) are created and networks follow power law of distribution ( model of Barabási and Albert 's ) . In opposite , in small world networks there are no hubs , and nodes are rather egalitarian and locally grouped in smaller clusters . These kind of networks are described by Watts and Strogatz ( WS ) model . All aforementioned models assume that newly added points have a global information about the whole network . However , in case of large systems , such knowledge is rather rare . This strongly limits nodes ' possibilities of connection choice . As a result , decisions about links are made rather in a local world than in the whole network . Networks which consider this locality are called local-world networks and were first described by the Li and Chen model ( 2003 ) .

To quantify this process , there is a need of inspection on how the size of the largest connected cluster within the network , , varies with . Networks change their topology as they evolve , undergoing phase transitions . Phase transitions are generally known from physics , where it occurs as matter changes state according to its thermal energy level , or when ferromagnetic properties emerge in some materials as they are cooling down . Such phase transitions take place in matter because it is a network of particles , and as such , rules of network phase transition directly apply to it . Phase transitions in networks happen as links are added to a network , meaning that having N nodes , in each time increment , a link is placed between a randomly chosen pair of them . The transformation from a set of disconnected nodes to a fully connected network is called the evolution of a network . If we begin with a network having N totally disconnected nodes ( number of links is zero ) , and start adding links between randomly selected pairs of nodes , the evolution of the network begins . For some time we will just create pairs of nodes . After a while some of these pairs will connect , forming little trees . As we continue adding more links to the network , there comes a point when a giant component emerges in the network as some of these isolated trees connect to each other . This is called the critical point . In our natural example , this point corresponds to temperatures where materials change their state . Further adding nodes to the system , the giant component becomes even larger , as more and more nodes get a link to an other node which is already part of the giant component . The other special moment in this transition is when the network becomes fully connected , that is , when all nodes belong to the one giant component , which is effectively the network itself at that point .", "qid": "527", "docid": "Evolution_of_a_random_network", "rank": 9, "score": 67292 }, { "content": "Title: Evolving networks Content: Evolving Networks are networks that change as a function of time .

In general a function is said to exhibit dynamic scaling if it satisfies Here the exponent is fixed by the dimensional requirement . Now , the numerical value of should remain invariant despite the unit of measurement of is changed by some factor since is a dimensionless quantity . However , Tamás Vicsek and Fereydoon Family first proposed the idea of dynamic scaling in the context of diffusion-limited aggregation DLA of clusters in two dimensions . The form of their proposal for dynamic scaling was Many phenomena which physicists often investigate are not static but rather evolve probabilistically with time . The universe is perhaps one of the best examples which is expanding ever since the Big Bang . Similarly , growth of networks like WWW , the Internet etc are also ever growing systems . Another example is polymer degradation process where degradation does not occur in a blink of an eye rather it happens over quite a long time . Spread of biological and computer viruses too does not happen over night . Many of these evolves in a self-similar fashion in the sense that data obtained from the snapshot at any fixed time is similar to the respective data taken from the snapshot of any earlier or later time . That is , the system is similar to itself at different times and hence it is often referred as self-similarity . The litmus test of such self-similarity is provided by the dynamic scaling . In such system we find certain stochastic variable which assume values that depend on time . In such cases , we are often interested to know the distribution of at various instant of time i.e. . Now the numerical value of and the typical or mean value of may well be very different at every different instant measurement . The question is : What happens to the corresponding dimensionless variables ? If the numerical values of the dimensional quantities are different , however , corresponding dimensionless quantities remain invariant then we can argue that the snapshot of the system at different times are similar . When this happens we conclude that the system is self-similar because the system is similar to itself at different time . One way of verifying the dynamic scaling is to plot dimensionless variables as a function of of the data extracted at various different time . Then if all the plots of vs obtained at different times collapse onto a single universal curve then it is said that the systems at different time are similar and it obeys dynamic scaling . The idea of data collapse is deeply rooted to the Buckingham theorem . Essentially such systems can be termed as temporal self-similarity since the same system is similar at different times . There have many seemingly disparate systems which are found to exhibit dynamic scaling e.g. , kinetics of aggregation described by Smoluchowski coagulation equation , complex network described by Barabasi -- Albert model , kinetic and stochastic Cantor set . The growth model within the Kardar -- Parisi -- Zhang ( KPZ ) class , one find that the width of the surface exhibits dynamic scaling .

Mars probably had oceans in the past , and it definitely had lakes and a thicker atmosphere . Modern Mars has become cold , dry , and almost uninhabitable , yet , if life did ever arise on Mars , some hardy microbes and perhaps even multicellular life might survive there right through to the present . The only missions to search for life on Mars , the two Viking missions , returned results that were inconclusive . However the instruments were not designed to cope with the unusual conditions which Viking discovered on Mars , which may have confused the results of the experiments . Also , they did n't know enough about Mars at that time to target the regions we now think are most likely to have present day life . Life would meet many challenges on present day Mars . Liquid water boils at 0 ° C , over much of its surface . Even at the depths of the Hellas basin , any water is close to its boiling point of 10 ° C and will dry out quickly . Ice also evaporates into the atmosphere over geological timescales - and most of the equatorial regions are thought to be dry to depths of tens of meters . As its axial tilt varies , Mars atmosphere is sometimes thicker , and liquid water may then form on the surface - but any dormant life in the top few meters of soil would be destroyed over periods of millions of years by cosmic radiation . However , in 2008 , droplets were observed on the landing legs of Phoenix . Sadly , there was no way to analyse them , but the leading hypothesis is that they were droplets of salty water . Phoenix also made isotopic measurements which show that the Mars atmosphere has exchanged oxygen molecules with liquid on the surface in the recent geological past . This could indicate either recent episodic occurrences of liquid water ( for instance after a meteorite strike ) or water present every year , in contact with the atmosphere . We now know of many seasonal changes in the surface of Mars which are only visible in high resolution photographs . Most of these are now thought to be caused by dry ice or wind effects . However , the `` Recurrent slope lineae '' , and some of the `` flow like features '' form in conditions that suggest the occasional presence of small quantities of water on Mars . The evidence of flowing brines in the RSLs is strong , though it 's not known if they are habitable . Curiosity has also found indirect evidence of a brine layer 15 cm below the sands that it drives over , though most scientists think that this layer is not habitable for Earth life . Recent Mars surface simulations by Nilton Renno and his team have shown that small droplets of water can form on salt / ice interfaces for a few hours per day almost anywhere on the surface of Mars , and this may explain the Phoenix leg droplets observations . In a separate development , research by the German aerospace company DLR in Mars simulation chambers and on the ISS show that some Earth life can survive simulated Mars surface conditions without any water at all , and photosynthesize and metabolize , slowly . It can do this using the high relative humidity of the Mars atmosphere at night . All of this work was done after the Phoenix discoveries in 2008 . Other potential habitats include lakes formed in the higher latitudes after cometary or meteorite impacts , or as a result of volcanism . Covered by ice , these may remain liquid for centuries , or up to a few thousand years for the largest impacts . The planet may also have underground trapped layers of water heated by geothermal hotspots . Also there are suggestions that Mars may have a deep hydrosphere , a liquid layer below its cryosphere , a few kilometers below the surface . Deep rock habitats on Earth are inhabited by life so if this layer exists , it may also be habitable on Mars . The main questions are Do these potential habitats exist ? Are they habitable ? For instance , liquid water , if present , could be too cold , or too salty for Earth life Are they in fact inhabited by any forms of life ? As Mars is so inhospitable , life might not be able to spread to new habitats easily . So there might be life in some of the habitats and not in others . Or life on Mars may have gone extinct , or never evolved at all , in which case none of the habitats would be inhabited . These discoveries have renewed interest in this topic , with many astrobiologists saying that they think present day Mars may be more habitable than previously thought .

Other fish evolved into land mammals and subsequently returned to the ocean as seals , dolphins or whales . Plant forms such as kelp and algae grow in the water and are the basis for some underwater ecosystems . Plankton , and particularly phytoplankton , are key primary producers forming the general foundation of the ocean food chain . Marine vertebrates must obtain oxygen to survive , and they do so in various ways . Fish have gills instead of lungs , although some species of fish , such as the lungfish , have both . Marine mammals , such as dolphins , whales , otters , and seals need to surface periodically to breathe air . Some amphibians are able to absorb oxygen through their skin . Invertebrates exhibit a wide range of modifications to survive in poorly oxygenated waters including breathing tubes ( see insect and mollusc siphons ) and gills ( Carcinus ) . However , as invertebrate life evolved in an aquatic habitat most have little or no specialisation for respiration in water . Altogether there are 230,000 documented marine species , including over 16,000 species of fish , and it has been estimated that nearly two million marine species are yet to be documented . Marine species range in size from the microscopic , including plankton and phytoplankton which can be as small as 0.02 micrometres , to huge cetaceans ( whales , dolphins and porpoises ) which in the case of the blue whale reach up to 33 metres ( 109 feet ) in length , being the largest known animal .", "qid": "527", "docid": "Marine_life", "rank": 21, "score": 61492 }, { "content": "Title: Sea Change Radio Content: Sea Change Radio is a weekly radio show whose mission is to advance the shift toward environmental sustainability .

According to Ward , humanity may exist for a long time . Nevertheless , we are impacting our world . He splits his book in different chronologies , starting with the near future ( the next 1,000 years ) . Humanity would be struggling to support a massive population of 11 billion . Global warming raises sea levels . The ozone layer weakens . Most of the available land is devoted to agriculture due to the demand for food . Despite all this , the oceanic wildlife remains untethered by most of these impacts , specifically the commercial farmed fish . This is , according to Ward , an era of extinction that would last about 10 million years ( note that many human-caused extinctions have already occurred ) . After that , the world gets stranger . Ward labels the species that have the potential to survive in a human-infested world . These include dandelions , raccoons , owls , pigs , cattle , rats , snakes , and crows to name but a few . In the human-infested ecosystem , those preadapted to live amongst man survived and prospered . Ward describes garbage dumps in the future infested with multiple species of rats , a snake with a sticky frog-like tongue to snap up rodents , and pigs with snouts specialized for rooting through garbage . The story 's time traveller who views this new refuse-covered habitat is gruesomely attacked by ravenous flesh-eating crows . Ward then questions the potential for humanity to evolve into a new species . According to him , this is incredibly unlikely . For this to happen a human population must isolate itself and interbreed until it becomes a new species . Then he questions if humanity would survive or extinguish itself by climate change , nuclear war , disease , or the posing threat of nanotechnology as terrorist weapons .", "qid": "527", "docid": "Future_Evolution", "rank": 25, "score": 59929 }, { "content": "Title: Global Sea Level Observing System Content: The Global Sea Level Observing System ( GLOSS ) is an Intergovernmental Oceanographic Commission program whose purpose is to measure sea level globally for long-term climate change studies .

After the initial breakup of the Allman Brothers Band when Gregg Allman and Dicky Betts left , most of the remaining members who evolved into Sea Level were the trio `` We Three '' comprising bassist Lamar Williams , drummer Jaimoe and Chuck Leavell ( piano , keyboards , vocals ) . The trio would occasionally open shows for the group in 1975 and 1976 . With the Allmans disbanding in 1976 , the trio added guitarist Jimmy Nalls and named the band based on a phonetic pun of their new bandleader Chuck Leavell 's name : `` C. Leavell . '' They toured relentlessly , experimenting and refining their sound , eventually signing with Capricorn Records ( home of the Allman Brothers ) and recording their self-titled debut album in 1977 . After the release of their first album , the group expanded to a septet with the additions of Davis Causey ( guitar ) , George Weaver ( drums , percussion ) and Randall Bramblett ( saxophones , keyboards and vocals ) . That configuration recorded the group 's second album , Cats on the Coast , in 1978 ( with the leadoff track , `` That 's Your Secret '' , reaching # 50 on the Billboard Hot 100 ) .

Some dinosaur groups which may or may not be true birds are listed below under ` Proto-birds ' . This page contains a listing of prehistoric bird taxa only known from completely fossilized specimens . These extinctions took place before the Late Quaternary and thus took place in the absence of significant human interference . While the earliest hominids had been eating birds and especially their eggs , human population and technology was simply insufficient to seriously affect healthy bird populations until the Upper Paleolithic Revolution . Rather , reasons for the extinctions listed here are stochastic abiotic events such as bolide impacts , climate change due to orbital shifts , mass volcanic eruptions etc. . Alternatively , species may have gone extinct due to evolutionary displacement by successor or competitor taxa -- it is notable that an extremely large number of seabirds have gone extinct during the mid-Tertiary ; this seems at least partly due to competition by the contemporary radiation of marine mammals . The relationships of these taxa are often hard to determine , as many are known only from very fragmentary remains and due to the complete fossilization precluding analysis of information from DNA , RNA or protein sequencing . The taxa listed in this article should be classified with the Wikipedia conservation status category `` Fossil '' . Before the late 19th century , when minerals were still considered one of the kingdoms of binomial nomenclature , fossils were often treated according to a parallel taxonomy . Rather than assigning them to animal or plant genera , they were treated as mineral genera and given binomial names typically using Osteornis ( `` bone-bird '' ) or Ornitholithus ( `` bird fossil '' ) as `` genus '' . The latter name , however , is still in use for an oogenus of fossil bird eggs . Also , other animals ( in particular pterosaurs ) were placed in these `` genera '' .

Panspermia is a hypothesis proposing that microscopic life forms that can survive the effects of space , such as extremophiles , become trapped in debris that is ejected into space after collisions between planets and small Solar System bodies that harbor life . Some organisms may travel dormant for an extended amount of time before colliding randomly with other planets or intermingling with protoplanetary disks . If met with ideal conditions on a new planet 's surfaces , the organisms become active and the process of evolution begins . Panspermia is not meant to address how life began , just the method that may cause its distribution in the Universe . Pseudo-panspermia ( sometimes called `` soft panspermia '' or `` molecular panspermia '' ) argues that the pre-biotic organic building blocks of life originated in space and were incorporated in the solar nebula from which the planets condensed and were further -- and continuously -- distributed to planetary surfaces where life then emerged ( abiogenesis ) . From the early 1970s it was becoming evident that interstellar dust consisted of a large component of organic molecules . Interstellar molecules are formed by chemical reactions within very sparse interstellar or circumstellar clouds of dust and gas . The dust plays a critical role of shielding the molecules from the ionizing effect of ultraviolet radiation emitted by stars . The chemistry leading to life may have begun shortly after the Big Bang , 13.8 billion years ago , during a habitable epoch when the Universe was only 10 -- 17 million years old . Though life is confirmed only on the Earth , some think that extraterrestrial life is not only plausible , but probable or inevitable .

With the exception of some ectothermic species like the leatherback sea turtle and crocodiles , no tetrapods weighing more than 25 kg survived . It marked the end of the Cretaceous period and with it , the entire Mesozoic Era , opening the Cenozoic Era that continues today . In the geologic record , the K -- Pg event is marked by a thin layer of sediment called the K -- Pg boundary , which can be found throughout the world in marine and terrestrial rocks . The boundary clay shows high levels of the metal iridium , which is rare in the Earth 's crust but abundant in asteroids . As originally proposed in 1980 by a team of scientists led by Luis Alvarez , it is now generally thought that the K -- Pg extinction was caused by a massive comet or asteroid impact , estimated to be 10 km wide , 66 million years ago and its catastrophic effects on the global environment , including a lingering impact winter that made it impossible for plants and plankton to carry out photosynthesis . The impact hypothesis , also known as the Alvarez hypothesis , was bolstered by the discovery of the 180 km Chicxulub crater in the Gulf of Mexico in the early 1990s , which provided conclusive evidence that the K -- Pg boundary clay represented debris from an asteroid impact . The fact that the extinctions occurred at the same time as the impact provides strong situational evidence that the K -- Pg extinction was caused by the asteroid . It was possibly accelerated by the creation of the Deccan Traps . However , some scientists maintain the extinction was caused or exacerbated by other factors , such as volcanic eruptions , climate change , or sea level change , separately or together . A wide range of species perished in the K -- Pg extinction . The best-known victims are the non-avian dinosaurs . However , the extinction also destroyed a plethora of other terrestrial organisms , including certain mammals , pterosaurs , birds , lizards , insects , and plants . In the oceans , the K -- Pg extinction killed off plesiosaurs and the giant marine lizards ( Mosasauridae ) and devastated fish , sharks , mollusks ( especially ammonites , which became extinct ) and many species of plankton . It is estimated that 75 % or more of all species on Earth vanished . Yet the devastation caused by the extinction also provided evolutionary opportunities . In the wake of the extinction , many groups underwent remarkable adaptive radiations -- a sudden and prolific divergence into new forms and species within the disrupted and emptied ecological niches resulting from the event .

These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end . These periods are caused by variations in eccentricity , axial tilt , and precession of the Earth 's orbit . As part of the ongoing supercontinent cycle , plate tectonics will probably result in a supercontinent in 250 -- 350 million years . Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present . This will cause the atmosphere to become a `` moist greenhouse '' , resulting in a runaway evaporation of the oceans . As a likely consequence , plate tectonics will come to an end , and with them the entire carbon cycle . Following this event , in about 2 − 3 billion years , the planet 's magnetic dynamo may cease , causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere . Four billion years from now , the increase in the Earth 's surface temperature will cause a runaway greenhouse effect , heating the surface enough to melt it . By that point , all life on the Earth will be extinct . The most probable fate of the planet is absorption by the Sun in about 7.5 billion years , after the star has entered the red giant phase and expanded to cross the planet 's current orbit .", "qid": "527", "docid": "Future_of_Earth", "rank": 71, "score": 55318 }, { "content": "Title: MSV Seawell Content: Seawell entered service in 1987 as a diving support vessel but it is widely credited with pioneering subsea light well intervention in the North Sea after completing its first well intervention project in 1988 .

It is located on the eastern part of the Darwin CBD on Knuckey Street . The roof of the tower is 100 metres above ground , reaching Darwin 's maximum height limit of 120 meters above sea level . The project was designed by architectural firm Burling Brown Architects and was built by Darwin-based Sunbuild . When first proposed in 2004 , the project faced opposition from the Department of Defence , who control the airspace over the city . Defence objected to the height of the tower which would be more than twice the height of any other building in Darwin at the time , calling for it to be reduced to 28 stories . Sunbuild successfully lobbied the department to have the height restriction raised in order to ensure the project 's viability and secure construction . The building will contain five commercial suites on the ground floor , 104 apartments , and two penthouse units . Construction began on Evolution in July 2006 and was completed in July 2008 .

The purpose of a sea wall is to protect areas of human habitation , conservation and leisure activities from the action of tides , waves , or tsunamis . As a seawall is a static feature it will conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea . The coast is generally a high-energy , dynamic environment with spatial variations over a wide range of timescales . The coast is exposed to erosion by rivers and winds as well as the sea , so that a combination of denudational processes will work against a sea wall . Because of these persistent natural forces , sea walls need to be maintained ( and eventually replaced ) to maintain their effectiveness . The many types of sea wall in use today reflect both the varying physical forces they are designed to withstand , and location specific aspects , such as local climate , coastal position , wave regime , and value of landform . Sea walls are hard engineering shore-based structures which protect the coast from erosion . But various environmental problems and issues may arise from the construction of a sea wall , including disrupting sediment movement and transport patterns . Combined with a high construction cost , this has led to an increasing use of other soft engineering coastal management options such as beach replenishment . Sea walls may be constructed from various materials , most commonly reinforced concrete , boulders , steel , or gabions . Other possible construction materials are : vinyl , wood , aluminium , fibreglass composite , and large biodegrable sandbags made of jute and coir .

Our evolving dynamic planet has survived[…] mass extinctions
[ { "content": "Title: Cretaceous–Paleogene extinction event Content: The Cretaceous -- Paleogene ( K -- Pg ) extinction event , also known as the Cretaceous -- Tertiary ( K -- T ) extinction , was a mass extinction of some three-quarters of the plant and animal species on Earth that occurred over a geologically short period of time approximately 65 million years ago . With the exception of some ectothermic species like the leatherback sea turtle and crocodiles , no tetrapods weighing more than 25 kg survived . It marked the end of the Cretaceous period and with it , the entire Mesozoic Era , opening the Cenozoic Era that continues today . In the geologic record , the K -- Pg event is marked by a thin layer of sediment called the K -- Pg boundary , which can be found throughout the world in marine and terrestrial rocks . The boundary clay shows high levels of the metal iridium , which is rare in the Earth 's crust but abundant in asteroids . As originally proposed in 1980 by a team of scientists led by Luis Alvarez , it is now generally thought that the K -- Pg extinction was caused by a massive comet or asteroid impact , estimated to be 10 km wide , 66 million years ago and its catastrophic effects on the global environment , including a lingering impact winter that made it impossible for plants and plankton to carry out photosynthesis . The impact hypothesis , also known as the Alvarez hypothesis , was bolstered by the discovery of the 180 km Chicxulub crater in the Gulf of Mexico in the early 1990s , which provided conclusive evidence that the K -- Pg boundary clay represented debris from an asteroid impact . The fact that the extinctions occurred at the same time as the impact provides strong situational evidence that the K -- Pg extinction was caused by the asteroid . It was possibly accelerated by the creation of the Deccan Traps . However , some scientists maintain the extinction was caused or exacerbated by other factors , such as volcanic eruptions , climate change , or sea level change , separately or together . A wide range of species perished in the K -- Pg extinction . The best-known victims are the non-avian dinosaurs . However , the extinction also destroyed a plethora of other terrestrial organisms , including certain mammals , pterosaurs , birds , lizards , insects , and plants . In the oceans , the K -- Pg extinction killed off plesiosaurs and the giant marine lizards ( Mosasauridae ) and devastated fish , sharks , mollusks ( especially ammonites , which became extinct ) and many species of plankton . It is estimated that 75 % or more of all species on Earth vanished . Yet the devastation caused by the extinction also provided evolutionary opportunities . In the wake of the extinction , many groups underwent remarkable adaptive radiations -- a sudden and prolific divergence into new forms and species within the disrupted and emptied ecological niches resulting from the event . Mammals in particular diversified in the Paleogene , producing new forms such as horses , whales , bats , and primates . Birds , fish and perhaps lizards also radiated .", "qid": "528", "docid": "Cretaceous–Paleogene_extinction_event", "rank": 1, "score": 105415 }, { "content": "Title: Extinction event Content: An extinction event ( also known as a mass extinction or biotic crisis ) is a widespread and rapid decrease in the biodiversity on Earth . Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms . It occurs when the rate of extinction increases with respect to the rate of speciation . Because the majority of diversity and biomass on Earth is microbial , and thus difficult to measure , recorded extinction events affect the easily observed , biologically complex component of the biosphere rather than the total diversity and abundance of life . Extinction occurs at an uneven rate . Based on the fossil record , the background rate of extinctions on Earth is about two to five taxonomic families of marine animals every million years . Marine fossils are mostly used to measure extinction rates because of their superior fossil record and stratigraphic range compared to land animals . The Great Oxygenation Event was probably the first major extinction event . Since the Cambrian explosion five further major mass extinctions have significantly exceeded the background extinction rate . The most recent and debatably best-known , the Cretaceous -- Paleogene extinction event , which occurred approximately million years ago ( Ma ) , was a large-scale mass extinction of animal and plant species in a geologically short period of time . In addition to the five major mass extinctions , there are numerous minor ones as well , and the ongoing mass extinction caused by human activity is sometimes called the sixth extinction . Mass extinctions seem to be a mainly Phanerozoic phenomenon , with extinction rates low before large complex organisms arose . Estimates of the number of major mass extinctions in the last 540 million years range from as few as five to more than twenty . These differences stem from the threshold chosen for describing an extinction event as `` major '' , and the data chosen to measure past diversity .", "qid": "528", "docid": "Extinction_event", "rank": 2, "score": 99918 }, { "content": "Title: Future of Earth Content: The biological and geological future of Earth can be extrapolated based upon the estimated effects of several long-term influences . These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end . These periods are caused by variations in eccentricity , axial tilt , and precession of the Earth 's orbit . As part of the ongoing supercontinent cycle , plate tectonics will probably result in a supercontinent in 250 -- 350 million years . Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present . This will cause the atmosphere to become a `` moist greenhouse '' , resulting in a runaway evaporation of the oceans . As a likely consequence , plate tectonics will come to an end , and with them the entire carbon cycle . Following this event , in about 2 − 3 billion years , the planet 's magnetic dynamo may cease , causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere . Four billion years from now , the increase in the Earth 's surface temperature will cause a runaway greenhouse effect , heating the surface enough to melt it . By that point , all life on the Earth will be extinct . The most probable fate of the planet is absorption by the Sun in about 7.5 billion years , after the star has entered the red giant phase and expanded to cross the planet 's current orbit .", "qid": "528", "docid": "Future_of_Earth", "rank": 3, "score": 98823 }, { "content": "Title: Red Queen hypothesis Content: The Red Queen hypothesis , also referred to as Red Queen 's , Red Queen 's race or the Red Queen effect , is an evolutionary hypothesis which proposes that organisms must constantly adapt , evolve , and proliferate not merely to gain reproductive advantage , but also simply to survive while pitted against ever-evolving opposing organisms in an ever-changing environment . The hypothesis intends to explain two different phenomena : the constant extinction rates as observed in the paleontological record caused by co-evolution between competing species , and the advantage of sexual reproduction ( as opposed to asexual reproduction ) at the level of individuals . Leigh Van Valen proposed the hypothesis to explain the `` Law of Extinction '' , showing that , in many populations , the probability of extinction does not depend on the lifetime of the population , instead being constant over millions of years for a given population . This could be explained by the coevolution of species . At other times , established species have evolved cooperatively by assuming adaptive coevolutionary dependencies . These complementary relationships develop through graduated symbiosis , directing punctuated advantages specialized enough to ensure a greater survivability and fitness rate for both species , coupled . Indeed , however , an adaptation in a population of one species ( e.g. predators , parasites ) may change the natural selection pressure on a population of another species ( e.g. prey , hosts ) , giving rise to common antagonistic coevolutions . If this positive feedback occurs reciprocally , a potential dynamic coevolution may result . In another idea , the Red Queen hypothesis is used independently by Hartung and Bell to explain the evolution of sex , by John Jaenike to explain the maintenance of sex and W. D. Hamilton to explain the role of sex in response to parasites . In all cases , sexual reproduction confers species variability and a faster generational response to selection by making offspring genetically unique . Sexual species are able to improve their genotype in changing conditions . Consequently , co-evolutionary interactions , between host and parasite , for example , may select for sexual reproduction in hosts in order to reduce the risk of infection . Oscillations in genotype frequencies are observed between parasites and hosts in an antagonistic coevolutionary way without necessitating changes to the phenotype .

For stars that lie near the plane of the Milky Way and are within a few thousand parsecs of the Earth , extinction in the visual band of frequencies ( photometric system ) is on the order of 1.8 magnitudes per kiloparsec . For Earth-bound observers , extinction arises both from the interstellar medium ( ISM ) and the Earth 's atmosphere ; it may also arise from circumstellar dust around an observed object . The strong atmospheric extinction in some wavelength regions ( such as X-ray , ultraviolet , and infrared ) requires the use of space-based observatories .

This page contains a listing of prehistoric bird taxa only known from completely fossilized specimens . These extinctions took place before the Late Quaternary and thus took place in the absence of significant human interference . While the earliest hominids had been eating birds and especially their eggs , human population and technology was simply insufficient to seriously affect healthy bird populations until the Upper Paleolithic Revolution . Rather , reasons for the extinctions listed here are stochastic abiotic events such as bolide impacts , climate change due to orbital shifts , mass volcanic eruptions etc. . Alternatively , species may have gone extinct due to evolutionary displacement by successor or competitor taxa -- it is notable that an extremely large number of seabirds have gone extinct during the mid-Tertiary ; this seems at least partly due to competition by the contemporary radiation of marine mammals . The relationships of these taxa are often hard to determine , as many are known only from very fragmentary remains and due to the complete fossilization precluding analysis of information from DNA , RNA or protein sequencing . The taxa listed in this article should be classified with the Wikipedia conservation status category `` Fossil '' . Before the late 19th century , when minerals were still considered one of the kingdoms of binomial nomenclature , fossils were often treated according to a parallel taxonomy . Rather than assigning them to animal or plant genera , they were treated as mineral genera and given binomial names typically using Osteornis ( `` bone-bird '' ) or Ornitholithus ( `` bird fossil '' ) as `` genus '' . The latter name , however , is still in use for an oogenus of fossil bird eggs . Also , other animals ( in particular pterosaurs ) were placed in these `` genera '' . In sources pre-dating the Linnean system , the above terms are also seen in the more extensive descriptions used to name taxa back then .", "qid": "528", "docid": "List_of_fossil_bird_genera", "rank": 6, "score": 92408 }, { "content": "Title: Alvarez hypothesis Content: The Alvarez hypothesis posits that the mass extinction of the dinosaurs and many other living things during the Cretaceous -- Paleogene extinction event was caused by the impact of a large asteroid on the Earth .

The hypothesis is named after the father-and-son team of scientists Luis and Walter Alvarez , who first suggested it in 1980 . In March 2010 , an international panel of scientists endorsed the asteroid hypothesis , specifically the Chicxulub impact , as being the cause of the extinction .

In the book , Kolbert chronicles previous mass extinction events , and compares them to the accelerated , widespread extinctions during our present time . She also describes specific species extinguished by humans , as well as the ecologies surrounding prehistoric and near-present extinction events .

The moment of extinction is generally considered to be the death of the last individual of the species , although the capacity to breed and recover may have been lost before this point . Because a species ' potential range may be very large , determining this moment is difficult , and is usually done retrospectively . This difficulty leads to phenomena such as Lazarus taxa , where a species presumed extinct abruptly `` reappears '' ( typically in the fossil record ) after a period of apparent absence . More than 99 percent of all species , amounting to over five billion species , that ever lived on Earth are estimated to be extinct . Estimates on the number of Earth 's current species range from 10 million to 14 million , of which about 1.2 million have been documented and over 86 percent have not yet been described . More recently , in May 2016 , scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described . Through evolution , species arise through the process of speciation -- where new varieties of organisms arise and thrive when they are able to find and exploit an ecological niche -- and species become extinct when they are no longer able to survive in changing conditions or against superior competition . The relationship between animals and their ecological niches has been firmly established . A typical species becomes extinct within 10 million years of its first appearance , although some species , called living fossils , survive with virtually no morphological change for hundreds of millions of years . Mass extinctions are relatively rare events ; however , isolated extinctions are quite common . Only recently have extinctions been recorded and scientists have become alarmed at the current high rate of extinctions . Most species that become extinct are never scientifically documented . Some scientists estimate that up to half of presently existing plant and animal species may become extinct by 2100 .

According to Ward , humanity may exist for a long time . Nevertheless , we are impacting our world . He splits his book in different chronologies , starting with the near future ( the next 1,000 years ) . Humanity would be struggling to support a massive population of 11 billion . Global warming raises sea levels . The ozone layer weakens . Most of the available land is devoted to agriculture due to the demand for food . Despite all this , the oceanic wildlife remains untethered by most of these impacts , specifically the commercial farmed fish . This is , according to Ward , an era of extinction that would last about 10 million years ( note that many human-caused extinctions have already occurred ) . After that , the world gets stranger . Ward labels the species that have the potential to survive in a human-infested world . These include dandelions , raccoons , owls , pigs , cattle , rats , snakes , and crows to name but a few . In the human-infested ecosystem , those preadapted to live amongst man survived and prospered . Ward describes garbage dumps in the future infested with multiple species of rats , a snake with a sticky frog-like tongue to snap up rodents , and pigs with snouts specialized for rooting through garbage . The story 's time traveller who views this new refuse-covered habitat is gruesomely attacked by ravenous flesh-eating crows . Ward then questions the potential for humanity to evolve into a new species . According to him , this is incredibly unlikely . For this to happen a human population must isolate itself and interbreed until it becomes a new species .

Consequently , celestial bodies at the horizon appear less bright than when at the zenith . The attenuation , known as atmospheric extinction , is described quantitatively by the Beer -- Lambert -- Bouguer law . `` Air mass '' normally indicates relative air mass , the path length relative to that at the zenith at sea level so , by definition , the sea-level air mass at the zenith is 1 . Air mass increases as the angle between the source and the zenith increases , reaching a value of approximately 38 at the horizon . Air mass can be less than one at an elevation greater than sea level ; however , most closed-form expressions for air mass do not include the effects of elevation , so adjustment must usually be accomplished by other means . In some fields , such as solar energy and photovoltaics , air mass is indicated by the acronym AM ; additionally , the value of the air mass is often given by appending its value to AM , so that AM1 indicates an air mass of 1 , AM2 indicates an air mass of 2 , and so on .

A major extinction , the Kellwasser event , occurred at the boundary that marks the beginning of the last phase of the Devonian period , the Famennian faunal stage ( the Frasnian -- Famennian boundary ) , about 375 -- 360 million years ago . Overall , 19 % of all families and 50 % of all genera became extinct . A second , distinct mass extinction , the Hangenberg event , closed the Devonian period . Although it is clear a massive loss of biodiversity occurred in the Later Devonian , the extent of time during which these events took place is uncertain , with estimates ranging from 500,000 to 25 million years , extending from the mid-Givetian to the end-Famennian . Nor is it clear whether it concerned two sharp mass extinctions or a series of smaller extinctions , though the latest research suggests multiple causes and a series of distinct extinction pulses through an interval of some three million years . Some consider the extinction to be as many as seven distinct events , spread over about 25 million years , with notable extinctions at the ends of the Givetian , Frasnian , and Famennian stages . By the late Devonian , the land had been colonized by plants and insects . In the oceans were massive reefs built by corals and stromatoporoids . Euramerica and Gondwana were beginning to converge into what would become Pangaea . The extinction seems to have only affected marine life . Hard-hit groups include brachiopods , trilobites , and reef-building organisms ; the reef-building organisms almost completely disappeared . The causes of these extinctions are unclear . Leading theories include changes in sea level and ocean anoxia , possibly triggered by global cooling or oceanic volcanism . The impact of a comet or another extraterrestrial body has also been suggested , such as the Siljan Ring event in Sweden . Some statistical analysis suggests the decrease in diversity was caused more by a decrease in speciation than by an increase in extinctions . This might have been caused by invasions of cosmopolitan species , rather than any single event . Surprisingly , jawed vertebrates seem to have been unaffected by the loss of reefs or other aspects of the Kellwasser event , while agnathans were in decline long before the end of the Frasnian .", "qid": "528", "docid": "Late_Devonian_extinction", "rank": 23, "score": 86018 }, { "content": "Title: Racing Extinction Content: Racing Extinction is a 2015 documentary about the ongoing Anthropogenic mass extinction of species and the efforts from scientists , activists and journalists to document it by Oscar-winning director Louie Psihoyos , who directed the documentary The Cove ( 2009 ) .

A chronology of this research is presented here . Paleontologists have recognized that a significant transition occurred between the Mesozoic and Cenozoic eras at least since the 1820s . Around this time dinosaur fossils were first being described in the scientific literature . Nevertheless , so few dinosaurs were known that the significance of their passing went unrecognized and little scientific effort was exerted toward finding an explanation . As more and more different kinds of dinosaurs were discovered , their extinction and replacement by mammals was recognized as significant but dismissed with little examination as a natural consequence of the mammals ' supposed innate superiority . Consequently , paleontologist Michael J. Benton has called the years up to 1920 as the `` Nonquestion Phase '' of Cretaceous -- Paleogene extinction research . Ideas that evolution might proceed along pre-ordained patterns or that evolutionary lineages might age , deteriorate , and die like individual animals became popular starting in the late 19th century , but were superseded by the Neo-Darwinian synthesis . The aftermath of this transition brought renewed interest to the extinction at the end of the Cretaceous . Paleontologists began dabbling in the subject , proposing environmental changes during the Cretaceous like mountain-building , dropping temperatures or volcanic eruptions as explanation for the extinction of the dinosaurs . Nevertheless , much of the research occurring during this period lacked rigor , evidential support or depended on tenuous assumptions . Michael J. Benton called the years between 1920 and 1970 the `` dilettante Phase '' of Cretaceous -- Paleogene extinction research . In 1970 , paleontologists began studying the Cretaceous -- Paleogene extinction in a detailed , rigorous way . Benton considered this to be the beginning of the `` Professional Phase '' of Cretaceous -- Paleogene extinction research . Early in this phase , the pace of the extinctions and the potential role of the Deccan Traps volcanism in India were major subjects of interest . In 1980 , father and son duo Luis and Walter Alvarez reported anomalously high levels of the platinum group metal iridium from the K -- Pg boundary , but because iridium is rare in Earth 's crust they argued that an asteroid impact was needed to account for it . This suggestion set off a bitter controversy . Evidence for an impact continued to mount , like the discovery of shocked quartz at the K -- Pg boundary . In 1991 , Alan Hildebrand and William Boynton reported the Chicxulub crater in the Yucatan peninsula of Mexico as a probable impact site . While the controversy continued , the accumulating evidence gradually began to sway the scientific community toward the Alvarez hypothesis . In 2010 , an international panel of researchers concluded that impact best explained the extinction event and that Chicxulub was indeed the resulting crater .", "qid": "528", "docid": "Timeline_of_Cretaceous–Paleogene_extinction_event_research", "rank": 27, "score": 84645 }, { "content": "Title: Medea hypothesis Content: The Medea hypothesis is a term coined by paleontologist Peter Ward for the anti-Gaian hypothesis that multicellular life , understood as a superorganism , is suicidal ; in this view , microbial-triggered mass extinctions are attempts to return the Earth to the microbial-dominated state it has been for most of its history .

New dating of the Popigai meteor suggests it may be a cause of the mass extinction . A leading scientific theory on climate cooling at this time is decrease in atmospheric carbon dioxide , which slowly declined in the mid to late Eocene and possibly reached some threshold approximately 34 million years ago .

With widespread degradation of highly biodiverse habitats such as coral reefs and rainforest , as well as other areas , the vast majority of these extinctions is thought to be undocumented . According to the species-area theory , and based on upper-bound estimating , the present rate of extinction may be up to 140,000 species per year , making it the greatest loss of biodiversity since the Cretaceous -- Paleogene extinction event . The Holocene extinction includes the disappearance of large land animals known as megafauna , starting at the end of the last Ice Age . Megafauna outside of the African continent , which did not evolve alongside humans , proved highly sensitive to the introduction of new predation , and many died out shortly after early humans began spreading and hunting across the Earth ( additionally , many African species have also gone extinct in the Holocene ) . These extinctions , occurring near the Pleistocene -- Holocene boundary , are sometimes referred to as the Quaternary extinction event . The arrival of humans on different continents coincides with megafaunal extinction . The most popular theory is that human overhunting of species added to existing stress conditions . Although there is debate regarding how much human predation affected their decline , certain population declines have been directly correlated with human activity , such as the extinction events of New Zealand and Hawaii . Aside from humans , climate change may have been a driving factor in the megafaunal extinctions , especially at the end of the Quaternary . The ecology of humanity has been noted as being that of an unprecedented `` global superpredator '' that regularly preys on the adults of other apex predators and has worldwide effects on food webs . Extinctions of species have occurred on every land mass and ocean , with many famous examples within Africa , Asia , Europe , Australia , North and South America , and on smaller islands . Overall , the Holocene extinction can be characterized by the human impact on the environment . The Holocene extinction continues into the 21st century , with meat consumption , overfishing , ocean acidification and the amphibian crisis being a few broader examples of an almost universal , cosmopolitan decline in biodiversity .

Extinction debt may be local or global , but most examples are local as these are easier to observe and model . It is most likely to be found in long-lived species and species with very specific habitat requirements ( specialists ) . Extinction debt has important implications for conservation , as it implies that species may become extinct due to past habitat destruction , even if continued impacts cease , and that current reserves may not be sufficient to maintain the species that occupy them .

'' However , this is a historical convention and should not imply that all extinct sloths were strictly terrestrial in nature . Their most recent survivors lived in the Antilles , where it has been proposed they may have survived until 1550 BCE ; however , radiocarbon dating suggests an age of between 2819 and 2660 BCE for the last known occurrence of Megalocnus in Cuba .

Their later survival in the Caribbean correlates with the later colonization of this area by humans . Some insular sloth populations persisted 5,000 -- 6,000 years longer than their continental mainland relatives , in congruence with the global pattern of late Quaternary large vertebrate extinction due to human dispersal . The bulk of ground sloth evolution took place during the mid to late Tertiary of South America while the continent was isolated . At their earliest appearance in the fossil record , the ground sloths were already distinct at the family level . The presence of intervening islands between the American continents in the Miocene allowed a dispersal of forms into North America . A number of mid - to small-sized forms are believed to have previously dispersed to the Antilles islands either by making short swims or using land bridges . Ground sloths were a hardy group as evidenced by their diverse numbers and dispersals into remote areas given the finding of their remains in Patagonia ( Cueva del Milodón ) and parts of Alaska . Sloths , and xenarthrans as a whole , represent one of the more successful South American groups during the Great American Biotic Interchange .

( The other being the earlier Selli Event , or OAE 1a , in the Aptian . ) The OAE 2 occurred approximately 91.5 ± 8.6 Ma , though other estimates are given as 93-94 Ma . The event brought about the extinction of the Spinosauridae , Pliosauridae , and possibly Ichthyosauria ; although coracoids of Maastrichtian age may belong to ichthyosaurs , indicating the survival of the group until the latest Cretaceous . Other animals lost some diversity as well . Although the cause is still uncertain , the result starved the Earth 's oceans of oxygen for nearly half a million years , causing the extinction of approximately 27 percent of marine invertebrates . This global environmental disturbance increased atmospheric and oceanic temperatures . Boundary sediments show an enrichment of trace elements , and contain elevated δ13C values . One possible cause was sub-oceanic volcanism , possibly the Caribbean large igneous province , with increased activity approximately 500,000 years earlier . During that period , the rate of crustal production reached its highest level for 100 million years . This was largely caused by the widespread melting of hot mantle plumes under the oceans at the base of the lithosphere . This resulted in the thickening of the oceanic crust in the Pacific and Indian Oceans . This volcanism would have sent large quantities of carbon dioxide into the atmosphere , leading to global warming . Within the oceans , the emission of SO2 , H2S , CO2 , and halogens would have increased the acidity of the water , causing the dissolution of carbonate , and a further release of carbon dioxide . When the volcanic activity declined , this run-away greenhouse effect would have likely been put into reverse . The increased CO2 content of the oceans could have increased organic productivity in the ocean surface waters . The consumption of this newly abundant organic life by aerobic bacteria would produce anoxia and mass extinction . The resulting elevated levels of carbon burial would account for the black shale deposition in the ocean basins .", "qid": "528", "docid": "Cenomanian-Turonian_boundary_event", "rank": 81, "score": 75608 }, { "content": "Title: Pseudoextinction Content: Pseudoextinction ( or phyletic extinction ) of a species occurs when all members of the species are extinct , but members of a daughter species remain alive . The term pseudoextinction refers to the evolution of a species into a new form , with the resultant disappearance of the ancestral form . Pseudoextinction results in the relationship between ancestor and descendant still existing even though the ancestor species no longer exists . The classic example is that of the dinosaurs . While the dinosaurs of the Mesozoic died out , their distant children , birds , live on today . As of now it is accepted that modern birds evolved from Archaeopteryx , a small dinosaur with flight feathers from the Mesozoic period . Many other families of bird-like dinosaurs also died out as the heirs of the dinosaurs continued to evolve , but because their birds continue to thrive in the world today these species are only pseudoextinct . From a taxonomic perspective , pseudoextinction is `` within an evolutionary lineage , the disappearance of one taxon caused by the appearance of the next . '' The pseudoextinction of a species can be arbitrary , simply resulting from a change in the naming of a species as it evolves from its ancestral form to its descendant form . Taxonomic pseudoextinction has to do with the disappearance of taxa that are categorized together by taxonomists . As they are just grouped together , their extinction is not reflected through lineage ; therefore , unlike evolutionary pseudoextinction , taxonomic pseudoextinction does not alter the evolution of daughter species . From an evolutionary perspective , pseudoextinction entails the loss of a species as a result of the creation of a new one . As the primordial species evolves into its daughter species , either by anagenesis or cladogenesis , the ancestral species can be subject to extinction . Throughout the process of evolution , a taxon can disappear ; in this case , pseudoextinction is considered an evolutionary event . From a genetic perspective , pseudoextinction is the `` disappearance of a taxon by virtue of its being evolved by anagenesis into another taxon . '' As all species must have an ancestor of a previous species , much of evolution is believed to occur through pseudoextinction . However , it is difficult to prove that any particular fossil species is pseudoextinct unless genetic information has been preserved . For example , it is sometimes claimed that the extinct Hyracotherium ( an ancient horse-like animal commonly known as an eohippus ) is pseudoextinct , rather than extinct , because several species of horse , including the zebra and the donkey , are extant today . However , it is not known , and probably can not be known , whether modern horses actually descend from members of the genus Hyracotherium , or whether they simply share a common ancestor . One proposed mechanism of pseudoextinction is endocrine disruption ( changing hormone levels ) . Additionally , when the primary sex-ratio ( male to female ratio of a population ) is male-biased , predicted levels of pseudoextinction increase . Because the variance of the population size increases with time , the probability of pseudoextinction increases with the length of the time horizon used . Mammal systematist and paleobiologist David Archibald has estimated that as many as 25 % of the extinctions recorded in three different early Puercan mammal lineages are pseudoextinctions . Pseudotermination is an extreme form of pseudoextinction , when a lineage continues as a new species ; phylogeny is often difficult to determine in such cases . Extirpation or regional disappearance can be a stage in pseudoextinction when progressive diachronous range contraction leads to final extinction by the elimination of the last refuge or population growth from this temporal bottleneck . The notion of pseudoextinction is sometimes applied to wider taxa than species . For instance , the entire superorder Dinosauria , as traditionally conceived , would have to be considered as pseudoextinct , because feathered dinosaurs are considered by the majority of modern palaeontologists as the ancestors of modern-day birds . Pseudoextinction for such higher taxa appears to be easier to prove . However , pseudoextinct higher taxa are paraphyletic groups , which are rejected as formal taxa in phylogenetic nomenclature ; either all dinosaurs are stem-group birds , or birds are derived dinosaurs , but there is no taxon Dinosauria , acceptable in cladistic taxonomy , that excludes the taxon Aves . Pseudoextinction can not be applied to the genus or family levels as , `` when a species evolves to a new form , causing the pseudoextinction of the ancestral form , the new species is normally assigned the same higher taxa as the ancestor . '' When a family or genus goes extinct it must be true extinction , because pseudoextinction would mean that at least one member of the family or genus is still extant . Pseudoextinction is an event that occurs much more frequently under the assumption of a Phyletic gradualism model of evolution , under which speciation is slow , uniform and gradual . The majority of speciation would occur through anagenesis under this model , resulting in a majority of species undergoing Pseudoextinction . However , the model of punctuated equilibrium is more widely accepted , with the proposal that most species remain in stasis , a state of very little evolutionary change , for a large proportion of the species ' lifespan . This would result in increased cases of speciation through cladogenesis and true extinction , with fewer cases of Pseudoextinction . Nearly all species undergo true extinction under the model of punctuated equilibrium . Charles Darwin proposed the idea of stasis in his book , On the Origin of Species . He suggested that species spend the majority of their evolutionary lifespan in the same form , having undergone very little morphological or genetic change . Another concept of species on the tree of life is the composite species concept . It sees one species as occupying all internodes of the tree that have the same combination of ( morphological , ecological , etc. ) characters . Here , a species starts with the acquisition of a character and ends when another change is fixed in its lineage . This process - of one lineage turning into what is afterwards seen as another species because of the fixation of a novel character - is often called anagenesis . But we have a similar situation here where a species is considered to end by definition but is not really extinct ( it survived , after all , in the form of one descendent species with a different character combination ) , and so we could also consider it to be pseudoextinction . On the other hand , under the composite species concept a species continues through a lineage split if only one of the two resulting lineages acquires a new character , an event that is sometimes called speciation through `` budding '' . The one that has a new character is now a new species but the other lineage , the one that looks identical to the common ancestor , is considered to be the common ancestor . An example would be a widespread breeding group remaining unchanged while `` budding off '' a small isolated population that accumulates changes until it can not interbreed with the others any more .", "qid": "528", "docid": "Pseudoextinction", "rank": 82, "score": 75572 }, { "content": "Title: Extinct comet Content: Extinct comets are comets that have expelled most of their volatile ice and have little left to form a tail or coma .

The specimens were originally catalogued in the American Museum of Natural History as Kingoria , however , with no formal reasoning for this categorization , this has since been revised with more up-to-date knowledge of features and speciation . Kingoria was defined early on as a close relative to Kombuisia and Hotton describes the two groups as sister Taxa . Kingoria and K. frerensis were relatively close geographically during there time of existence . Kingoria fossils are found in the mid to southern region of Africa .

However , in terms of proportion of production exported , Australia was the world 's second largest coal exporter , with exports accounting for roughly 73 % of coal production . Indonesia exports about 87 % of its coal production . Coal mining in Australia has been criticised by members of the environmental movement , due to carbon dioxide emissions during combustion . This criticism is primarily directed at thermal coal , for its connection to coal-fired power stations as a major source of carbon dioxide emissions , and the link to climate change and the effects of global warming on Australia . The burning of coal for electricity produces 29 % of Australia 's total greenhouse gas emissions , based on 2013-2014 Clean Energy Regulator data . Both Greenpeace Australia Pacific ( Energy -LSB- R -RSB- evolution ) and Beyond Zero Emissions ( Zero Carbon Australia 2020 ) have produced reports claiming a transition can be made to renewable energy and Greenpeace has called for a just transition for coal based communities , but others argue at present there is no strong evidence of a viable alternative for the vast majority of Australia 's electricity generation , or for the significant economic and social benefits coal mining delivers to regional communities . Many of these arguments specifically ignore the differentiation between thermal and metallurgical coal , and the different application they play in modern society . Coal Seam Gas , methane-based gas associated with deposits of coal has historically been flared , however over the past 10 years has been recovered and used to generate further electricity .

The state comprises less than 8 percent of the Australian population and ranks fifth in population among the six states and two territories . The majority of its people reside in Adelaide . Most of the remainder are settled in fertile areas along the south-eastern coast and River Murray . The state 's colonial origins are unique in Australia as a freely settled , planned British province , rather than as a convict settlement . Official settlement began on 28 December 1836 , when the colony was proclaimed at the Old Gum Tree by Governor John Hindmarsh . As with the rest of the continent , the region had been long occupied by Aboriginal peoples , who were organised into numerous tribes and languages . The first British settlement to be established was Kingscote , Kangaroo Island , on 26 July 1836 , five months before Adelaide was founded . The guiding principle behind settlement was that of systematic colonisation , a theory espoused by Edward Gibbon Wakefield that was later employed by the New Zealand Company . The goal was to establish the province as a centre of civilisation for free immigrants , promising civil liberties and religious tolerance . Although its history is marked by economic hardship , South Australia has remained politically innovative and culturally vibrant .

Following the Japanese Fukushima nuclear disaster in early 2011 , many countries are scaling back their nuclear power production , with some setting deadlines for a complete shutdown of all nuclear power reactors . It is expected that this may impact on demand for Australian Uranium . However , State governments have now approved mine development in Western Australia and Queensland . But as of 2013 uranium prices are very low , and it is unlikely that any new projects will enter active development until the market improves . Historically , many prospective Australian uranium mines have been constrained by active antinuclear opposition . For several decades uranium mining has been a major part of the Australian political landscape , with opposition groups citing the wide ranging environmental impacts , indigenous land access and nuclear proliferation as reasons for ceasing or restricting the industry . The debate has resulted in limitations on mining and export activities , with Federal and State governments occasionally backflipping on public policy .

Though more expensive to produce , requiring a $ 0.33 / litre Federal subsidy , a 2006 report found it would likely save at least $ 27 million per year when the social and health costs of petrol-sniffing were taken into account . A 2010 senate report showed that the introduction of Opal in 106 communities across remote and regional Australia had led to a 70 % drop in petrol sniffing in those communities . Typical unleaded petrol contains 25 % aromatics , such as toluene , ortho-xylene and para-xylene . In contrast , Opal contains only 5 % aromatics , which means that it has less of the toluene and other solvents which produce the intoxication ( or `` high '' ) that inhalant users are seeking . The Australian Government subsidizes Opal 's provision and restricts traditional unleaded petrol in some remote communities . According to BP , the lower volatile component in Opal means that cars using it are less prone to vapor lock .

Similar to many other countries , development of renewable electricity in Australia has been encouraged by government energy policy implemented in response to concerns about climate change , energy independence and economic stimulus . A key policy that has been in place since 2001 to encourage large-scale renewable energy development is a mandatory renewable energy target , which in 2010 was increased to 41,000 gigawatt-hours of renewable generation from power stations . This was subsequently reduced to 33,000 gigawatt-hours by the Abbott Government with the agreement of the Labor opposition . Alongside this there is the Small-Scale Renewable Energy Scheme , an uncapped scheme to support rooftop solar power and solar hot water and several State schemes providing feed-in tariffs to encourage photovoltaics . In 2012 , these policies were supplemented by a carbon price and a 10 billion-dollar fund to finance renewable energy projects , although these initiatives were later withdrawn by the Federal Government .

Australia subsidizes fossil fuel energy , keeping prices artificially low and raising greenhouse gas emissions due to the increased use of fossil fuels as a result of the subsidies . The Australian Energy Regulator and state agencies such as the New South Wales ' Independent Pricing and Regulatory Tribunal set and regulate electricity prices , thereby lowering production and consumer cost . According to a report by The Institute for Sustainable Futures ( ISF ) at University of Technology Sydney , titled : `` Energy and Transport Subsidies in Australia '' , roughly 70 % of the country 's greenhouse gas emissions are caused by the energy and transport industries . The uptake of renewable energy in these sectors is slow because of subsidies to fossil fuels and the high cost of acquiring the sophisticated technology required to produce cleaner fuels . Furthermore , fossil fuels are easier to transport and use , compared to renewable energy , which often require sophisticated instruments to acquire and store . The report revealed that for the 2005 -- 2006 financial year , transport subsidies were measured to reach up to $ 10.1 billion , of which 74 % related to transport , 18 % to electricity and 4 % to renewable and efficient energy . These subsidies help energy generation companies increase their profits , therefore encouraging the building of additional coal-fuel power plants . Investing in other , more sustainable , types of electricity generation plants would have cost less than continuing to subsidize the building of these power plants . On a positive note , alternative transport fuels such as natural gas and liquefied petroleum gas are excused from fuel excise/tax . Tax calculated for the use of a company car is calculated as such : the further the person drives the car , the higher the business use and the lower the personal use . Since tax is calculated based on personal use , drivers tend to drive longer distances to lessen the amount of tax that they have to pay . This leads to a higher consumption of vehicular fossil fuels and , subsequently , higher greenhouse gas emissions . Dr Hal Turton , the Group Leader of the Energy Economics Group at Swiss research establishment , the Paul Scherrer Institute , discussed in his report for Canberra-based think tank The Australia Institute titled : `` The Aluminium Smelting Industry : Structure , Market Power , Subsidies and Greenhouse Gas Emissions '' , that the yearly electrical use subsidy for the use of the six aluminium smelters in Australia is at least A$ 210 million . According to the report , Australia 's aluminium smelting industry is party to one of the most subsidized electricity charges as compared to other similar establishments . The ISF report found that removing electrical subsidies would bring up electricity prices by 3.9 % , which would lead to a fall in demand of electricity by 1.4 % in the long run . Reducing transport subsidies would increase prices by 32 % , which would lead to a fall in demand worth 18 % . It suggests that subsidies should be removed gradually so as not to hurt drivers who have no choice but to use petrol ( due to the lack of alternatives ) , and that taxpayer 's funds be channeled to subsidize the sustainable energy industry instead . The National Roads and Motorists ' Association ( NRMA ) is pushing for Australian petrol consumption to be reduced by 50 % by 2050 . It is advocating a move towards greener transport , and has called for a reduction of the A$ 10 billion subsidies given to the nation 's fossil fuel industry .", "qid": "531", "docid": "Environmental_impact_of_transport_in_Australia", "rank": 37, "score": 128795 }, { "content": "Title: Ladbroke Grove Power Station Content: Ladbroke Grove Power Station is a gas-fired power station near Penola in the Limestone Coast region of South Australia .

A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide , or 12 per cent of all greenhouse gases emitted by the sector . Venting of natural gas , flaring , accidental releases and storage losses accounted for an additional 38 per cent . Fugitive emissions present other risks and hazards . Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities . In situations where large amounts of flammable liquids and gases are contained under pressure , leaks also increase the risk of fire and explosion . Leaks from pressurized process equipment generally occur through valves , pipe connections , mechanical seals , or related equipment . Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks . Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks , fugitive emissions can be a significant proportion of total emissions . Though the quantities of leaked gases may be small , gases that have serious health or environmental impacts can cause a significant problem . To minimize and control leaks at process facilities operators carry out regular leak detection and repair activities . Routine inspections of process equipment with gas detectors can be used to identify leaks and estimate the leak rate in order to decide on appropriate corrective action . Proper routine maintenance of equipment reduces the likelihood of leaks . Because of the technical difficulties and costs of detecting and quantifying actual fugitive emissions at a site or facility , and the variability and intermittent nature of emission flow rates , bottom-up estimates based on standard emission factors are generally used for annual reporting purposes . New technologies are under development that could revolutionize the detection and monitoring of fugitive emissions . One technology , known as differential absorption lidar ( DIAL ) , can be used to remotely measure concentration profiles of hydrocarbons in the atmosphere up to several hundred meters from a facility . DIAL has been used for refinery surveys in Europe for over 15 years . A pilot study carried out in 2005 using DIAL found that actual emissions at a refinery were fifteen times higher than those previously reported using the emission factor approach . The fugitive emissions were equivalent to 0.17 % of the refinery throughput . Portable gas leak imaging cameras are also a new technology that can be used to improve leak detection and repair , leading to reduced fugitive emissions . The cameras use infrared imaging technology to produce video images in which invisible gases escaping from leak sources can be clearly identified .", "qid": "532", "docid": "Fugitive_emissions", "rank": 24, "score": 117171 }, { "content": "Title: Sustainable automotive air conditioning Content: Sustainable automotive air conditioning is the subject of a debate -- nicknamed the Cool War -- about the next-generation refrigerant in car air conditioning .

Wind power , as an alternative to burning fossil fuels , is plentiful , renewable , widely distributed , clean , produces no greenhouse gas emissions during operation , consumes no water , and uses little land . The net effects on the environment are far less problematic than those of nonrenewable power sources . Wind farms consist of many individual wind turbines which are connected to the electric power transmission network . Onshore wind is an inexpensive source of electric power , competitive with or in many places cheaper than coal or gas plants . Offshore wind is steadier and stronger than on land , and offshore farms have less visual impact , but construction and maintenance costs are considerably higher . Small onshore wind farms can feed some energy into the grid or provide electric power to isolated off-grid locations . Wind power gives variable power which is very consistent from year to year but which has significant variation over shorter time scales . It is therefore used in conjunction with other electric power sources to give a reliable supply . As the proportion of wind power in a region increases , a need to upgrade the grid , and a lowered ability to supplant conventional production can occur . Power management techniques such as having excess capacity , geographically distributed turbines , dispatchable backing sources , sufficient hydroelectric power , exporting and importing power to neighboring areas , using vehicle-to-grid strategies or reducing demand when wind production is low , can in many cases overcome these problems . In addition , weather forecasting permits the electric power network to be readied for the predictable variations in production that occur . As of 2015 , Denmark generates 40 % of its electric power from wind , and at least 83 other countries around the world are using wind power to supply their electric power grids .

That charge , called a carbon price , is the amount that must be paid for the right to emit one tonne of CO2 into the atmosphere . Carbon pricing usually takes the form either of a carbon tax or a requirement to purchase permits to emit , generally known as cap-and-trade , but also called `` allowances '' . Carbon pricing solves the economic problem that , a known greenhouse gas , is what economics calls a negative externality -- a detrimental product that is not priced ( charged for ) by any market . As a consequence of not being priced , there is no market mechanism responsive to the costs of CO2 emitted . The standard economic solution to problems of this type , first proposed by Arthur Pigou in 1920 , is for the product - in this case , CO2 emissions - to be charged at a price equal to the monetary value of the damage caused by the emissions . This should result in the economically optimal ( efficient ) amount of CO2 emissions . Many practical concerns mar the theoretical simplicity of this picture : for example , the exact monetary damage caused by a tonne of CO2 is uncertain . The economics of carbon pricing is much the same for taxes and cap-and-trade . Both prices are efficient ; they have the same social cost and the same effect on profits if permits are auctioned . However , some economists argue that caps prevent non-price policies , such as renewable energy subsidies , from reducing carbon emissions , while carbon taxes do not . Others argue that an enforced cap is the only way to guarantee that carbon emissions will actually be reduced ; a carbon tax will not prevent those who can afford to do so from continuing to generate emissions .

A carbon tax is generally favored on economic grounds for its simplicity and stability , while cap-and-trade is often favored on political grounds .

CDR is a different approach than removing CO2 from the stack emissions of large fossil fuel point sources , such as power stations . The latter reduces emission to the atmosphere but can not reduce the amount of carbon dioxide already in the atmosphere . As CDR removes carbon dioxide from the atmosphere , it creates negative emissions , offsetting emissions from small and dispersed point sources such as domestic heating systems , airplanes and vehicle exhausts . It is regarded by some as a form of climate engineering , while other commentators describe it as a form of carbon capture and storage or extreme mitigation .

Carbon offsets are measured in metric tons of carbon dioxide-equivalent ( CO2e ) and may represent six primary categories of greenhouse gases : carbon dioxide , methane ( CH4 ) , nitrous oxide ( N2O ) , perfluorocarbons ( PFCs ) , hydrofluorocarbons ( HFCs ) , and sulfur hexafluoride ( SF6 ) . One carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases . There are two markets for carbon offsets . In the larger , compliance market , companies , governments , or other entities buy carbon offsets in order to comply with caps on the total amount of carbon dioxide they are allowed to emit . This market exists in order to achieve compliance with obligations of Annex 1 Parties under the Kyoto Protocol , and of liable entities under the EU Emission Trading Scheme . In 2006 , about $ 5.5 billion of carbon offsets were purchased in the compliance market , representing about 1.6 billion metric tons of CO2e reductions . In the much smaller , voluntary market , individuals , companies , or governments purchase carbon offsets to mitigate their own greenhouse gas emissions from transportation , electricity use , and other sources . For example , an individual might purchase carbon offsets to compensate for the greenhouse gas emissions caused by personal air travel . Many companies ( see list ) offer carbon offsets as an up-sell during the sales process so that customers can mitigate the emissions related with their product or service purchase ( such as offsetting emissions related to a vacation flight , car rental , hotel stay , consumer good , etc. ) . In 2008 , about $ 705 million of carbon offsets were purchased in the voluntary market , representing about 123.4 million metric tons of CO2e reductions . Some fuel suppliers in the UK offer fuel which has been carbon offset such as Fuel dyes . Offsets are typically achieved through financial support of projects that reduce the emission of greenhouse gases in the short - or long-term . The most common project type is renewable energy , such as wind farms , biomass energy , or hydroelectric dams . Others include energy efficiency projects , the destruction of industrial pollutants or agricultural byproducts , destruction of landfill methane , and forestry projects . Some of the most popular carbon offset projects from a corporate perspective are energy efficiency and wind turbine projects . Carbon offsetting has gained some appeal and momentum mainly among consumers in western countries who have become aware and concerned about the potentially negative environmental effects of energy-intensive lifestyles and economies . The Kyoto Protocol has sanctioned offsets as a way for governments and private companies to earn carbon credits that can be traded on a marketplace . The protocol established the Clean Development Mechanism ( CDM ) , which validates and measures projects to ensure they produce authentic benefits and are genuinely `` additional '' activities that would not otherwise have been undertaken . Organizations that are unable to meet their emissions quota can offset their emissions by buying CDM-approved Certified Emissions Reductions . Emissions from burning fuel , such as red diesel , has pushed one UK fuel supplier to create a carbon offset fuel named Carbon Offset Red Diesel . Offsets may be cheaper or more convenient alternatives to reducing one 's own fossil-fuel consumption . However , some critics object to carbon offsets , and question the benefits of certain types of offsets . Due diligence is recommended to help businesses in the assessment and identification of `` good quality '' offsets to ensure offsetting provides the desired additional environmental benefits , and to avoid reputational risk associated with poor quality offsets . Offsets are viewed as an important policy tool to maintain stable economies and to improve sustainability . One of the hidden dangers of climate change policy is unequal prices of carbon in the economy , which can cause economic collateral damage if production flows to regions or industries that have a lower price of carbon -- unless carbon can be purchased from that area , which offsets effectively permit , equalizing the price .", "qid": "532", "docid": "Carbon_offset", "rank": 66, "score": 105351 }, { "content": "Title: Carbon Emission Reduction Target Content: The Carbon Emission Reduction Target ( CERT ) in the United Kingdom ( formerly the Energy Efficiency Commitment ) is a target imposed on the gas and electricity transporters and suppliers under Section 33BC of the Gas Act 1986 and Section 41A of the Electricity Act 1989 , as modified by the Climate Change and Sustainable Energy Act 2006 The original Energy Efficiency Commitment 1 ( 2002 -- 2005 ) program required that all electricity and gas suppliers with 15,000 or more domestic customers must achieve a combined energy saving of 62 TWh by 2005 by assisting their customers to take energy-efficiency measures in their homes : suppliers had to achieve at least half of their energy savings in households on income-related benefits and tax credits .

The aim is to prevent the release of large quantities of into the atmosphere ( from fossil fuel use in power generation and other industries ) . It is a potential means of mitigating the contribution of fossil fuel emissions to global warming and ocean acidification . Although has been injected into geological formations for several decades for various purposes , including enhanced oil recovery , the long term storage of is a relatively new concept . The first commercial example was the Weyburn-Midale Carbon Dioxide Project in 2000 . Other examples include SaskPower 's Boundary Dam and Mississippi Power 's Kemper Project . ` CCS ' can also be used to describe the scrubbing of from ambient air as a climate engineering technique . An integrated pilot-scale CCS power plant was to begin operating in September 2008 in the eastern German power plant Schwarze Pumpe run by utility Vattenfall , to test the technological feasibility and economic efficiency . CCS applied to a modern conventional power plant could reduce emissions to the atmosphere by approximately 80 -- 90 % compared to a plant without CCS . The IPCC estimates that the economic potential of CCS could be between 10 % and 55 % of the total carbon mitigation effort until year 2100 . Carbon dioxide can be captured out of air or fossil fuel power plant flue gas using adsorption ( or carbon scrubbing ) , membrane gas separation , or adsorption technologies . Amines are the leading carbon scrubbing technology . Capturing and compressing may increase the energy needs of a coal-fired CCS plant by 25 -- 40 % . These and other system costs are estimated to increase the cost per watt energy produced by 21 -- 91 % for fossil fuel power plants . Applying the technology to existing plants would be more expensive , especially if they are far from a sequestration site . A 2005 industry report suggests that with successful research , development and deployment ( RD&D ) , sequestered coal-based electricity generation in 2025 may cost less than unsequestered coal-based electricity generation today . Storage of the is envisaged either in deep geological formations , or in the form of mineral carbonates . Deep ocean storage is not currently considered feasible due to the associated effect of ocean acidification . Geological formations are currently considered the most promising sequestration sites . The National Energy Technology Laboratory ( NETL ) reported that North America has enough storage capacity for more than 900 years worth of carbon dioxide at current production rates .

Carbon dioxide removal addresses the cause of global warming by removing one of the greenhouse gases ( carbon dioxide ) from the atmosphere . Solar radiation management attempts to offset effects of greenhouse gases by causing the Earth to absorb less solar radiation .

Almost all research into solar radiation management has consisted of computer modelling or laboratory tests , and an attempt to move to outdoor experimentation was controversial . Some carbon dioxide removal practices , such as planting of trees and bio-energy with carbon capture and storage projects , are underway . Their scalability to effectively affect global climate is , however , debated . Ocean iron fertilization has been given small-scale research trials , sparking substantial controversy .

Potential tipping points have been identified in the physical climate system, in impacted ecosystems, and sometimes in both. For instance, feedback from the global carbon cycle is a driver for the transition between glacial and interglacial periods, with orbital forcing providing the initial trigger. Earth's geologic temperature record includes many more examples of geologically rapid transitions between different climate states.Climate tipping points are of particular interest in reference to concerns about global warming in the modern era. Possible tipping point behaviour has been identified for the global mean surface temperature by studying self-reinforcing feedbacks and the past behavior of Earth's climate system. Self-reinforcing feedbacks in the carbon cycle and planetary reflectivity could trigger a cascading set of tipping points that lead the world into a hothouse climate state.Large-scale components of the Earth system that may pass a tipping point have been referred to as tipping elements. Tipping elements are found in the Greenland and Antarctic ice sheets, possibly causing tens of meters of sea level rise. These tipping points are not always abrupt. For example, at some level of temperature rise the melt of a large part of the Greenland ice sheet and/or West Antarctic Ice Sheet will become inevitable; but the ice sheet itself may persist for many centuries.

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction . Climate changes is projected to affect individual organisms , populations , species distributions and ecosystem composition and function both directly ( ex . Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) . Every organism has a unique set of preferences or requirements , a niche and biodiversity has been tied to the diversity of animals ' niches . These can include or be affected by temperature , aridity , resource availability , habitat requirements , enemies , soil characteristics , competitors , and pollinators .

These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end . These periods are caused by variations in eccentricity , axial tilt , and precession of the Earth 's orbit . As part of the ongoing supercontinent cycle , plate tectonics will probably result in a supercontinent in 250 -- 350 million years . Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present . This will cause the atmosphere to become a `` moist greenhouse '' , resulting in a runaway evaporation of the oceans . As a likely consequence , plate tectonics will come to an end , and with them the entire carbon cycle . Following this event , in about 2 − 3 billion years , the planet 's magnetic dynamo may cease , causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere . Four billion years from now , the increase in the Earth 's surface temperature will cause a runaway greenhouse effect , heating the surface enough to melt it .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

Circulation in the atmosphere and oceans is primarily driven by solar radiation and transports heat from the tropical regions to regions that receive less energy from the Sun. The water cycle also moves energy throughout the climate system. In addition, different chemical elements, necessary for life, are constantly recycled between the different components. The climate system can change due to internal variability and external forcings. These external forcings can be natural, such as variations in solar intensity and volcanic eruptions, or caused by humans.

The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago .

The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon .

Most weather phenomena occur in the lowest level of the atmosphere , the troposphere , just below the stratosphere . Weather refers to day-to-day temperature and precipitation activity , whereas climate is the term for the averaging of atmospheric conditions over longer periods of time . When used without qualification , `` weather '' is generally understood to mean the weather of Earth . Weather is driven by air pressure , temperature and moisture differences between one place and another . These differences can occur due to the sun 's angle at any particular spot , which varies with latitude . The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations : the Hadley Cell , the Ferrel Cell , the Polar Cell , and the jet stream . Weather systems in the mid-latitudes , such as extratropical cyclones , are caused by instabilities of the jet stream flow . Because the Earth 's axis is tilted relative to its orbital plane , sunlight is incident at different angles at different times of the year . On Earth 's surface , temperatures usually range ± 40 ° C ( − 40 ° F to 100 ° F ) annually . Over thousands of years , changes in Earth 's orbit can affect the amount and distribution of solar energy received by the Earth , thus influencing long-term climate and global climate change . Surface temperature differences in turn cause pressure differences . Higher altitudes are cooler than lower altitudes as most atmospheric heating is due to contact with the Earth 's surface while radiative losses to space are mostly constant . Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location . The Earth 's weather system is a chaotic system ; as a result , small changes to one part of the system can grow to have large effects on the system as a whole . Human attempts to control the weather have occurred throughout history , and there is evidence that human activities such as agriculture and industry have modified weather patterns .

A famous landmark in the Solar System , Jupiter 's Great Red Spot , is an anticyclonic storm known to have existed for at least 300 years . However , weather is not limited to planetary bodies .

These variations can explain events such as ice ages and the Great Oxygenation Event , while the Sun 's future expansion into a red giant will likely end life on Earth . Solar activity and related events have been recorded since the 8th century BCE . Babylonians inscribed and possibly predicted solar eclipses , while the earliest extant report of sunspots dates back to the Chinese Book of Changes , . The first extant description of the solar corona was in 968 , while the earliest sunspot drawing was in 1128 and a solar prominence was described in 1185 in the Russian Chronicle of Novgorod . The invention of the telescope allowed major advances in understanding , allowing the first detailed observations in the 1600s . Solar spectroscopy began in the 1800s , from which properties of the solar atmosphere could be determined , while the creation of daguerreotypy led to the first solar photographs on 2 April 1845 . Photography assisted in the study of solar prominences , granulation and spectroscopy . Early in the 20th century , interest in astrophysics surged in America . A number of new observatories were built with solar telescopes around the world . The 1931 invention of the coronagraph allowed the corona to be studied in full daylight .", "qid": "534", "docid": "Solar_phenomena", "rank": 53, "score": 75129 }, { "content": "Title: Hot air (economics) Content: Hot air in economics refers to the Assigned Amount Units ( AAU ) credits given for the reduction of Green House Gas ( GHG ) emissions among the former Soviet Bloc countries since 1990 .

The first phase of the global heatwaves was caused by a moderate El Niño event , which lasted from June 2009 to May 2010 . The first phase lasted only from April 2010 to June 2010 , and caused only moderate above average temperatures in the areas affected . But it also set new record high temperatures for most of the area affected , in the Northern Hemisphere . The second phase ( the main , and most devastating phase ) was caused by a very strong La Niña event , which lasted from June 2010 to June 2011 . According to meteorologists , the 2010 -- 11 La Niña event was one of the strongest La Niña events ever observed . That same La Niña event also had devastating effects in the Eastern states of Australia .

The heat wave during the summer of 2010 was at its worst in June , over the Eastern United States , Middle East , Eastern Europe and European Russia , and over Northeastern China and southeastern Russia . June 2010 marked the fourth consecutive warmest month on record globally , at 0.66 ° C ( 1.22 ° F ) above average , while the period April -- June was the warmest ever recorded for land areas in the Northern Hemisphere , at 1.25 ° C ( 2.25 ° F ) above average . The previous record for the global average temperature in June was set in 2005 at 0.66 ° C ( 1.19 ° F ) , and the previous warm record for April -- June over Northern Hemisphere land areas was 1.16 ° C ( 2.09 ° F ) , set in 2007 . Sometime during June 2010 , the highest recorded temperature caused by the heatwave was 53.5 ° C , in Southeastern Russia , just north of Kazakhstan . The strongest of the anticyclones , the one situated over Siberia , registered a maximum high pressure of 1040 millibars . The weather caused forest fires in China , where three in a team of 300 died fighting a fire that broke out in the Binchuan County of Dali , as Yunnan suffered the worst drought in 60 years by February 17 .

The term is named after Serbian geophysicist and astronomer Milutin Milanković . In the 1920s , he theorized that variations in eccentricity , axial tilt , and precession of the Earth 's orbit resulted in cyclical variation in the solar radiation ( insolation ) reaching the Earth , and that this orbital forcing strongly influenced climatic patterns on Earth . The Earth 's orbit varies between nearly circular and mildly elliptical ( its eccentricity varies ) . When the orbit is more elongated , there is more variation in the distance between the Earth and the Sun , and in the amount of solar radiation , at different times in the year . In addition , the rotational tilt of the Earth ( its obliquity ) , which causes the seasons as the Earth revolves around the Sun , changes slightly . A greater tilt makes the seasons more extreme . Finally , the direction in the fixed stars pointed to by the Earth 's axis changes ( axial precession ) , while the Earth 's elliptical orbit around the Sun rotates ( apsidal precession ) . The combined effect of the two precessions is a cycle in which proximity to the Sun occurs during different astronomical seasons . If the Earth is closer to the Sun while the northern or southern hemisphere is tilted toward the Sun ( is in summer ) , then both effects work together to heat that hemisphere . If the Earth is further from the Sun during summer , the greater distance slightly reduces the heat of summer . Similar astronomical theories had been advanced in the 19th century by Joseph Adhemar , James Croll and others , but verification was difficult because there was no reliably dated evidence , and because it was unclear which periods were important . Now , materials on Earth that have been unchanged for millennia are being studied to indicate the history of Earth 's climate . A study of the chronology of Antarctic ice cores using oxygen-nitrogen ratios in air bubbles trapped in the ice , which appear to respond directly to the local insolation , concluded that the climatic response documented in the ice cores was driven by northern hemisphere insolation as proposed by the Milankovitch hypothesis . Analysis of deep-ocean cores and a seminal paper by Hays , Imbrie , and Shackleton provide additional validation of the Milankovitch hypothesis through physical artifacts .

The neoglaciation has no well-marked universal beginning : local conditions and ecological inertia affected the onset of detectably cooler ( and wetter ) conditions . Driven inexorably by the Milankovitch cycle , cooler summers in higher latitudes of North America , which would cease to completely melt the annual snowfall , were masked at first by the presence of the slowly disappearing continental ice sheets , which persisted long after the astronomically calculated moment of maximum summer warmth : `` the neoglaciation can be said to have begun when the cooling caught up with the warming '' , remarked E. C. Pielou . With the close of the `` Little Ice Age '' ( mid-14th to late 19th centuries ) , neoglaciation appears to have been stalled in the late 20th century , assumed to be caused by anthropogenic global warming . Whether it has been temporarily or semi-permanently stalled , neoglaciation has been marked by a retreat from the warm conditions of the Climatic Optimum and the advance or reformation of glaciers that had not existed since the last ice age . In the mountains of western North America , montane glaciers that had completely melted reformed shortly before 5000 BP . The most severe part of the best documented neoglacial period , especially in Europe and the North Atlantic , is termed the `` Little Ice Age '' . In North America , neoglaciation had ecological effects in the spread of muskeg on flat , poorly drained land , such as the bed of recently drained Lake Agassiz and in the Hudson Bay lowlands , in the retreat of grassland before an advancing forest border in the Great Plains , and in shifting ranges of forest trees and diagnostic plant species ( identified through palynology ) .

Much of this energy is lost when the earth re-radiates it back into outer space , and the rest of the energy is distributed throughout the five components of Earth 's climate system . This system is made up of earth 's water , ice , atmosphere , rocky crust , and all living things . Quantifying changes in these amounts is required to accurately model the Earth 's climate . Received radiation is unevenly distributed over the planet , because the Sun heats equatorial regions more than polar regions . Energy is absorbed by the atmosphere , hydrosphere , and lithosphere , and , in a process informally described as Earth 's heat engine , the solar heating is redistributed through evaporation of surface water , convection , rainfall , winds , and ocean circulation . When the incoming solar energy is balanced by an equal flow of heat to space , the Earth is said to be in radiative equilibrium and under that condition , global temperatures will be stable . Disturbances of Earth 's radiative equilibrium , such as an increase of greenhouse gases , will change global temperatures in response . However , Earth 's energy balance and heat fluxes depend on many factors , such as atmospheric composition ( mainly aerosols and greenhouse gases ) , the albedo ( reflectivity ) of surface properties , cloud cover and vegetation and land use patterns . Changes in surface temperature due to Earth 's energy budget do not occur instantaneously , due to the inertia of the oceans and the cryosphere . The net heat flux is buffered primarily by becoming part of the ocean 's heat content , until a new equilibrium state is established between radiative forcings and the climate response .", "qid": "534", "docid": "Earth's_energy_budget", "rank": 82, "score": 70340 }, { "content": "Title: Hot House (British band) Content: Hot House ( also billed as `` Hot!House '' ) were an English soul music band featuring Heather Small , Martin Colyer and Mark Pringle , who first came to the attention of the British Music Press ( Record Mirror etc. ) in January 1987 .

Martian geysers are distinct from geysers on Earth, which are typically associated with hydrothermal activity. These are unlike any terrestrial geological phenomenon. The reflectance (albedo), shapes and unusual spider appearance of these features have stimulated a variety of hypotheses about their origin, ranging from differences in frosting reflectance, to explanations involving biological processes. However, all current geophysical models assume some sort of jet or geyser-like activity on Mars. Their characteristics, and the process of their formation, are still a matter of debate. These features are unique to the south polar region of Mars in an area informally called the 'cryptic region', at latitudes 60° to 80° south and longitudes 150°W to 310°W; this 1 meter deep carbon dioxide (CO2) ice transition area—between the scarps of the thick polar ice layer and the permafrost—is where clusters of the apparent geyser systems are located. The seasonal frosting and defrosting of carbon dioxide ice results in the appearance of a number of features, such dark dune spots with spider-like rilles or channels below the ice, where spider-like radial channels are carved between the ground and the carbon dioxide ice, giving it an appearance of spider webs, then, pressure accumulating in their interior ejects gas and dark basaltic sand or dust, which is deposited on the ice surface and thus, forming dark dune spots. This process is rapid, observed happening in the space of a few days, weeks or months, a growth rate rather unusual in geology – especially for Mars.

Thermohaline circulation of the world 's oceans involves the flow of warm surface waters from the southern hemisphere into the North Atlantic . Water flowing northward becomes modified through evaporation and mixing with other water masses , leading to increased salinity . When this water reaches the North Atlantic it cools and sinks through convection , due to its decreased temperature and increased salinity resulting in increased density . NADW is the outflow of this thick deep layer , which can be detected by its high salinity , high oxygen content , nutrient minima , and chlorofluorocarbons ( CFCs ) . CFCs are anthropogenic substances that enter the surface of the ocean from gas exchange with the atmosphere .

It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide . A GWP is calculated over a specific time interval , commonly 20 , 100 , or 500 years . GWP is expressed as a factor of carbon dioxide ( whose GWP is standardized to 1 ) . In the Fifth Assessment Report of the Intergovernmental Panel on Climate Change , methane has a lifetime of 12.4 years and with climate-carbon feedbacks a global warming potential of 86 over 20 years and 34 over 100 years in response to emissions . User related choices such as the time horizon can greatly affect the numerical values obtained for carbon dioxide equivalents . For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph . Because the GWP of a greenhouse gas depends directly on its infrared spectrum , the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change .", "qid": "538", "docid": "Global_warming_potential", "rank": 66, "score": 94841 }, { "content": "Title: Stordalen (Sweden) Content: Stordalen mire ( elevation 351 m ) lies in the subarctic region in northernmost Sweden .

The palsas are dry , ombrotrophic plateaus ( or hummocks ) with permafrost cores that raise the peat surface above its surroundings that is the wet minerotrophic depressions , largely permafrost free and water saturated . The small-scale topography is often very patchy in its structure , creating an environment where localities nearby each other have distinct differences in moisture , permafrost and nutrient status , which creates differences in vegetation types . Of these subhabitats the vegetation in the dry parts consists mainly of mosses , lichens and dwarf shrubs , whereas the wet parts are dominated by sphagnum or tall graminoids . A peat layer up to 3 m deep covers most of the area and is an indication of a net carbon accumulation over the past 5000 years . In the areas underlying by permafrost the active layer reaches a thickness of about 60 cm in the late summer .

This includes respiration of plant roots , the rhizosphere , microbes and fauna . Soil respiration is a key ecosystem process that releases carbon from the soil in the form of CO2 . CO2 is acquired from the atmosphere and converted into organic compounds in the process of photosynthesis . Plants use these organic compounds to build structural components or respire them to release energy . When plant respiration occurs below-ground in the roots , it adds to soil respiration . Over time , plant structural components are consumed by heterotrophs . This heterotrophic consumption releases CO2 and when this CO2 is released by below-ground organisms , it is considered soil respiration . The amount of soil respiration that occurs in an ecosystem is controlled by several factors . The temperature , moisture , nutrient content and level of oxygen in the soil can produce extremely disparate rates of respiration . These rates of respiration can be measured in a variety of methods . Other methods can be used to separate the source components , in this case the type of photosynthetic pathway ( C3/C4 ) , of the respired plant structures . Soil respiration rates can be largely affected by human activity . This is because humans have the ability to and have been changing the various controlling factors of soil respiration for numerous years . Global climate change is composed of numerous changing factors including rising atmospheric CO2 , increasing temperature and shifting precipitation patterns . All of these factors can affect the rate of global soil respiration . Increased nitrogen fertilization by humans also has the potential to effect rates over the entire Earth . Soil respiration and its rate across ecosystems is extremely important to understand . This is because soil respiration plays a large role in global carbon cycling as well as other nutrient cycles . The respiration of plant structures releases not only CO2 but also other nutrients in those structures , such as nitrogen . Soil respiration is also associated with positive feedbacks with global climate change . Positive feedbacks are when a change in a system produces response in the same direction of the change .

Sinusoidal estimates of expected temperatures , for northern locales , usually place the lowest temperatures around January 23 and the highest around July 24 , and provide fairly accurate estimates of temperature expectations . Actual average temperatures in North America usually significantly differ twice over the course of the year : Mid-autumn temperatures tend to be warmer than predicted by the sinusoidal model , creating the impression of extended summer warmth known as Indian summer . For five days around January 25 , temperatures are usually significantly warmer than predicted by the sinusoidal estimate , and also warmer than neighboring temperatures on both sides . During this `` thaw '' period , usually lasting for about a week , temperatures are generally about 6 ° C ( 10 ° F ) above normal . This varies from year to year , and temperatures fluctuate enough that such a rise in late-January temperature would be unremarkable ; what is remarkable ( and unexplained ) is the tendency for such rises to occur more commonly in late January than in mid-January or early February , which sinusoidal estimates have to be slightly warmer . In some regions ( such as northern Canada ) this phenomenon will not be manifest as a `` thaw '' in the technical sense , since temperatures will remain below freezing . The January thaw is believed to be a weather singularity . A possible physical mechanism for such phenomena was offered in the 1950s by E.G. Bowen : he suggested that some `` calendaricities '' ( as he called them ) might be explicable in terms of meteoric particles from cometary orbits acting as ice nuclei in terrestrial clouds ; his theory then received some support from several sources . However , Bowen 's ideas later fell out of favour with the development of atmospheric dynamic modelling techniques , although one of his rainfall peaks does seem to correspond with the date of the January thaw .

Climate change mitigation generally involves reductions in human ( anthropogenic ) emissions of greenhouse gases ( GHGs ) . Mitigation may also be achieved by increasing the capacity of carbon sinks , e.g. , through reforestation . Mitigation policies can substantially reduce the risks associated with human-induced global warming . According to the IPCC 's 2014 assessment report , `` Mitigation is a public good ; climate change is a case of the ` tragedy of the commons . Effective climate change mitigation will not be achieved if each agent ( individual , institution or country ) acts independently in its own selfish interest ( see international cooperation and emissions trading ) , suggesting the need for collective action . Some adaptation actions , on the other hand , have characteristics of a private good as benefits of actions may accrue more directly to the individuals , regions , or countries that undertake them , at least in the short term . Nevertheless , financing such adaptive activities remains an issue , particularly for poor individuals and countries . '' Examples of mitigation include phasing out fossil fuels by switching to low-carbon energy sources , such as renewable and nuclear energy , and expanding forests and other `` sinks '' to remove greater amounts of carbon dioxide from the atmosphere . Energy efficiency may also play a role , for example , through improving the insulation of buildings . Another approach to climate change mitigation is climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) . The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of GHGs at a level that would prevent dangerous human interference of the climate system . Scientific analysis can provide information on the impacts of climate change , but deciding which impacts are dangerous requires value judgments . In 2010 , Parties to the UNFCCC agreed that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . With the Paris Agreement of 2015 this was confirmed , but was revised with a new target laying down `` parties will do the best '' to achieve warming below 1.5 ° C . The current trajectory of global greenhouse gas emissions does not appear to be consistent with limiting global warming to below 1.5 or 2 ° C .

A carbon diet is an effective way to understand the amount of impact on the environment and how to make meaningful changes .

Trees : Protecting forests and planting new trees contributes to the absorption of carbon dioxide from the air . There are many opportunities to plant trees in the yard , along roads , in parks , and in public gardens . In addition , some charities plant fast-growing trees -- for as little as $ US0 .10 per tree -- to help people in tropical developing countries restore the productivity of their lands . Conversely , clearing old-growth forests adds to the carbon in the atmosphere , so buying non-old-growth paper is good for the climate as well as the forest .

More than a third of Americans have changed their travel habits in 2008 , versus only 14 % in 2007 . Cars : Purchasing a vehicle which gets high gas mileage helps to reduce emissions of carbon dioxide . Flying : Avoiding air travel and particularly frequent flyer programs has a high benefit because the convenience makes frequent , long distance travel easy , and high-altitude emissions are more potent for the climate than the same emissions made at ground level . Walking and running are among the least environmentally harmful modes of transportation , followed by the bicycle . Many energy suppliers in various countries worldwide have options to purchase part or pure `` green energy .

Every unit of carbon that is absorbed by trees -- or not emitted due to your funding of renewable energy deployment -- offsets the emissions from their fossil fuel use . In many cases , funding of renewable energy , energy efficiency , or tree planting -- particularly in developing nations -- can be a relatively cheap way of making an individual `` carbon neutral '' .

Normal respiration is driven mostly by the levels of carbon dioxide in the arteries , which are detected indirectly by central chemoreceptors when carbon dioxide crosses the blood -- brain barrier , forming detectable hydrogen ions , and directly by peripheral chemoreceptors , and very little by the oxygen levels . An increase in carbon dioxide will cause chemoreceptor reflexes to trigger an increase in ventilation . Hypoxic drive normally accounts for 10 % of the total drive to breathe . This increases as the PaO2 drops to 70 torr and below , while hypoxic drive is no longer active when PaO2 exceeds 170 torr . The hypoxic drive is so weak that unconsciousness will develop before respiratory distress is noted and is therefore a risk for pilots flying at high altitudes . For this reason , supplemental oxygen is required by Federal Aviation Regulations for pilots flying above an altitude of about 12,500 feet in unpressurized airplanes .

In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century .

Climate is the average weather, typically over a period of 30 years, and is determined by a combination of processes in the climate system, such as ocean currents and wind patterns. Circulation in the atmosphere and oceans is primarily driven by solar radiation and transports heat from the tropical regions to regions that receive less energy from the Sun. The water cycle also moves energy throughout the climate system. In addition, different chemical elements, necessary for life, are constantly recycled between the different components. The climate system can change due to internal variability and external forcings. These external forcings can be natural, such as variations in solar intensity and volcanic eruptions, or caused by humans. Accumulation of heat-trapping greenhouse gases, mainly being emitted by people burning fossil fuels, is causing global warming. Human activity also releases cooling aerosols, but their net effect is far less than that of greenhouse gases.

The Earth is much cooler and so radiates heat back away from itself at much longer wavelengths , mostly in the infrared range . The idealized greenhouse model is based on the fact that certain gases in the Earth 's atmosphere , including carbon dioxide and water vapour , are transparent to the high-frequency , high-energy solar radiation , but are much more opaque to the lower frequency infrared radiation leaving the surface of the earth . Thus heat is easily let in , but is partially trapped by these gases as it tries to leave . Rather than get hotter and hotter , Kirchhoff 's law of thermal radiation says that the gases of the atmosphere also have to re-emit the infrared energy that they absorb , and they do so , also at long infrared wavelengths , both upwards into space as well as downwards back towards the Earth 's surface . In the long-term , thermal equilibrium is reached when all the heat energy arriving on the planet is leaving again at the same rate . In this idealized model , the greenhouse gases cause the surface of the planet to be warmer than it would be without them , in order for the required amount of heat energy finally to be radiated out into space from the top of the atmosphere . The greenhouse effect can be illustrated with an idealized planet . This is a common `` textbook model '' : the planet will have a constant surface temperature Ts and an atmosphere with constant temperature Ta . For diagrammatic clarity , a gap can be depicted between the atmosphere and the surface . Alternatively , Ts could be interpreted as a temperature representative of the surface and the lower atmosphere , and Ta could be interpreted as the temperature of the upper atmosphere . In order to justify that Ta and Ts remain constant over the planet , strong ocean and atmospheric currents can be imagined to provide plentiful lateral mixing .

Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world . The latter effect is currently causing global warming , and `` climate change '' is often used to describe human-specific impacts .", "qid": "539", "docid": "History_of_climate_change_science", "rank": 28, "score": 116506 }, { "content": "Title: 2015 United Nations Climate Change Conference Content: The 2015 United Nations Climate Change Conference , COP 21 or CMP 11 was held in Paris , France , from 30 November to 12 December 2015 .

The conference negotiated the Paris Agreement , a global agreement on the reduction of climate change , the text of which represented a consensus of the representatives of the 196 parties attending it . The agreement will enter into force when joined by at least 55 countries which together represent at least 55 percent of global greenhouse emissions . On 22 April 2016 ( Earth Day ) , 174 countries signed the agreement in New York , and began adopting it within their own legal systems ( through ratification , acceptance , approval , or accession ) .

The agreement calls for zero net anthropogenic greenhouse gas emissions to be reached during the second half of the 21st century . In the adopted version of the Paris Agreement , the parties will also `` pursue efforts to '' limit the temperature increase to 1.5 ° C .

The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph . Because the GWP of a greenhouse gas depends directly on its infrared spectrum , the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change .", "qid": "539", "docid": "Global_warming_potential", "rank": 36, "score": 114034 }, { "content": "Title: Adiabatic accessibility Content: Adiabatic accessibility denotes a certain relation between two equilibrium states of a thermodynamic system ( or of different such systems ) . The concept was coined by Constantin Carathéodory in 1909 ( `` adiabatische Erreichbarkeit '' ) and taken up 90 years later by Elliott Lieb and J. Yngvason in their axiomatic approach to the foundations of thermodynamics . It was also used by R. Giles in his 1964 monograph . A system in a state Y is said to be adiabatically accessible from a state X if X can be transformed into Y without the system suffering transfer of energy as heat or transfer of matter . X may , however , be transformed to Y by doing work on X. For example , a system consisting of one kilogram of warm water is adiabatically accessible from a system consisting of one kilogram of cool water , since the cool water may be mechanically stirred to warm it . However , the cool water is not adiabatically accessible from the warm water , since no amount or type of work may be done to cool it . The original definition of Carathéodory was limited to reversible , quasistatic process , described by a curve in the manifold of equilibrium states of the system under consideration . He called such a state change adiabatic if the infinitesimal ` heat ' differential form vanishes along the curve . In other words , at no time in the process does heat enter or leave the system . Carathéodory 's formulation of the Second Law of Thermodynamics then takes the form : `` In the neighbourhood of any initial state , there are states which can not be approached arbitrarily close through adiabatic changes of state . '' From this principle he derived the existence of entropy as a state function whose differential is proportional to the heat differential form , so it remains constant under adiabatic state changes ( in Carathéodory 's sense ) . The increase of entropy during irreversible processes is not obvious in this formulation , without further assumptions . The definition employed by Lieb and Yngvason is rather different since the state changes considered can be the result of arbitrarily complicated , possibly violent , irreversible processes and there is no mention of ` heat ' or differential forms . In the example of the water given above , if the stirring is done slowly , the transition from cool water to warm water will be quasistatic . However , a system containing an exploded firecracker is adiabatically accessible from a system containing an unexploded firecracker ( but not vice versa ) , and this transition is far from quasistatic . Lieb and Yngvason 's definition of adiabatic accessibility is : A state is adiabatically accessible from a state , in symbols , if it is possible to transform into in such a way that the only net effect of the process on the surroundings is that a weight has been raised or lowered ( or a spring is stretched/compressed , or a flywheel is set in motion ) . A definition of thermodynamic entropy can be based entirely on certain properties of the relation of adiabatic accessibility that are taken as axioms in the Lieb-Yngvason approach . In the following list of properties of the operator , a system is represented by a capital letter , e.g. X , Y or Z . A system X whose extensive parameters are multiplied by is written . ( e.g. for a simple gas , this would mean twice the amount of gas in twice the volume , at the same pressure . ) A system consisting of two subsystems X and Y is written ( X , Y ) . If and are both true , then each system can access the other and the transformation taking one into the other is reversible . This is an equivalence relationship written . Otherwise , it is irreversible . Adiabatic accessibility has the following properties : Reflexivity : Transitivity : If and then Consistency : if and then Scaling Invariance : if and then Splitting and Recombination : for all Stability : if then The entropy has the property that if and only if and if and only if in accord with the Second Law .

It was launched in 2005 to fight Global warming and is a major pillar of EU climate policy . As of 2013 , the EU ETS covers more than 11,000 factories , power stations , and other installations with a net heat excess of 20 MW in 31 countries -- all 28 EU member states plus Iceland , Norway , and Liechtenstein . In 2008 , the installations regulated by the EU ETS were collectively responsible for close to half of the EU 's anthropogenic emissions of CO2 and 40 % of its total greenhouse gas emissions . Under the ` cap and trade ' principle , a maximum ( cap ) is set on the total amount of greenhouse gases that can be emitted by all participating installations . ` Allowances ' for emissions are then auctioned off or allocated for free , and can subsequently be traded . Installations must monitor and report their CO2 emissions , ensuring they hand in enough allowances to the authorities to cover their emissions . If emission exceeds what is permitted by its allowances , an installation must purchase allowances from others . Conversely , if an installation has performed well at reducing its emissions , it can sell its leftover credits . This allows the system to find the most cost-effective ways of reducing emissions without significant government intervention . The scheme has been divided into a number of `` trading periods '' . The first ETS trading period lasted three years , from January 2005 to December 2007 . The second trading period ran from January 2008 until December 2012 , coinciding with the first commitment period of the Kyoto Protocol . The third trading period began in January 2013 and will span until December 2020 . Compared to 2005 , when the EU ETS was first implemented , the proposed caps for 2020 represents a 21 % reduction of greenhouse gases . This target has been reached 6 years early as emissions in the ETS fell to 1812 mln tonnes in 2014 . The EU ETS has seen a number of significant changes , with the first trading period described as a ` learning by doing ' phase . Phase III sees a turn to auctioning a majority of permits rather than allocating freely ; harmonisation of rules for the remaining allocations ; and the inclusion of other greenhouse gases , such as nitrous oxide and perfluorocarbons . In 2012 , the EU ETS was also extended to the airline industry , though this has been paused for one year given the possibility of a global system for these emissions . The price of EU ETS carbon credits has been lower than intended , with a large surplus of allowances , in part because of the impact of the recent economic crisis on demand . In 2012 , the Commission said it would delay the auctioning of some allowances . Currently legislation is under way which would introduce a Market Stability Reserve to the EU ETS that adjusts the annual supply of CO2 permits based on the CO2 permits in circulation .

An example of this is quasi-static compression , where the volume of a system changes at a rate slow enough to allow the pressure to remain uniform and constant throughout the system . Any reversible process is necessarily a quasi-static one . However , quasi-static processes involving entropy production are irreversible . An example of a quasi-static process that is not reversible is a compression against a system with a piston subject to friction -- although the system is always in thermal equilibrium , the friction ensures the generation of dissipative entropy , which directly goes against the definition of reversible . A notable example of a process that is not even quasi-static is the slow heat exchange between two bodies at two finitely different temperatures , where the heat exchange rate is controlled by an approximately adiabatic partition between the two bodies -- in this case , no matter how slowly the process takes place , the states of the two bodies are never infinitesimally close to equilibrium , since thermal equilibrium requires that the two bodies be at the same temperature . Some ambiguity exists in the literature concerning the distinction between quasi-static and reversible processes , as these are sometimes taken as synonyms .

In practical situations , it is essential to differentiate between the two : any engineer would remember to include friction when calculating the dissipative entropy generation , so there are no reversible processes in practice .

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction . Climate changes is projected to affect individual organisms , populations , species distributions and ecosystem composition and function both directly ( ex . Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) . Every organism has a unique set of preferences or requirements , a niche and biodiversity has been tied to the diversity of animals ' niches . These can include or be affected by temperature , aridity , resource availability , habitat requirements , enemies , soil characteristics , competitors , and pollinators . Since the factors that compose a niche can be so complex and interconnected , the niches of many animals are bound to be affected by climate change ( Parmesan Yohe 2003 ) . One study done by Camille Parmesan and Gary Yohe from University of Texas , Austin shows the global fingerprint of climate change on natural systems . The results of their global analysis of 334 species were recorded to demonstrate the correlation of patterns consistent with global climate change of the 20th century . Using the IPCC 's ( Intergovernmental Panel on Climate Change ) ` levels of confidence ' , this study proved significant nonrandom behavioral changes due to global climate change with very high confidence ( > 95 ) .

Due to the lack of solar heating and very strong radiative cooling from carbon dioxide , the mesosphere is the coldest region on Earth with temperatures as low as -100 ° C ( -148 ° F or 173 K ) . The altitude of the mesopause for many years was assumed to be at around 85 km ( 53 mi . ) , but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km . ( 62 mi . ) Another feature is that the summer mesopause is cooler than the winter ( sometimes referred to as the mesopause anomaly ) . It is due to a summer-to-winter circulation giving rise to upwelling at the summer pole and downwelling at the winter pole . Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause . In the mesosphere the summer-to-winter circulation is due to gravity wave dissipation , which deposits momentum against the mean east-west flow , resulting in a small north-south circulation . In recent years the mesopause has also been the focus of studies on global climate change associated with increases in CO2 . Unlike the troposphere , where greenhouse gases result in the atmosphere heating up , increased CO2 in the mesosphere acts to cool the atmosphere due to increased radiative emission . This results in a measurable effect - the mesopause should become cooler with increased CO2 . Observations do show a decrease of temperature of the mesopause , though the magnitude of this decrease varies and is subject to further study .

By volume , dry air contains 78.09 % nitrogen , 20.95 % oxygen , 0.93 % argon , 0.04 % carbon dioxide , and small amounts of other gases . Air also contains a variable amount of water vapor , on average around 1 % at sea level , and 0.4 % over the entire atmosphere . Air content and atmospheric pressure vary at different layers , and air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in Earth 's troposphere and in artificial atmospheres .

As well as the economic cost of lost commodities , fugitive emissions contribute to air pollution and climate change . A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide , or 12 per cent of all greenhouse gases emitted by the sector . Venting of natural gas , flaring , accidental releases and storage losses accounted for an additional 38 per cent . Fugitive emissions present other risks and hazards . Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities . In situations where large amounts of flammable liquids and gases are contained under pressure , leaks also increase the risk of fire and explosion . Leaks from pressurized process equipment generally occur through valves , pipe connections , mechanical seals , or related equipment . Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks . Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks , fugitive emissions can be a significant proportion of total emissions . Though the quantities of leaked gases may be small , gases that have serious health or environmental impacts can cause a significant problem . To minimize and control leaks at process facilities operators carry out regular leak detection and repair activities . Routine inspections of process equipment with gas detectors can be used to identify leaks and estimate the leak rate in order to decide on appropriate corrective action . Proper routine maintenance of equipment reduces the likelihood of leaks . Because of the technical difficulties and costs of detecting and quantifying actual fugitive emissions at a site or facility , and the variability and intermittent nature of emission flow rates , bottom-up estimates based on standard emission factors are generally used for annual reporting purposes . New technologies are under development that could revolutionize the detection and monitoring of fugitive emissions . One technology , known as differential absorption lidar ( DIAL ) , can be used to remotely measure concentration profiles of hydrocarbons in the atmosphere up to several hundred meters from a facility . DIAL has been used for refinery surveys in Europe for over 15 years . A pilot study carried out in 2005 using DIAL found that actual emissions at a refinery were fifteen times higher than those previously reported using the emission factor approach . The fugitive emissions were equivalent to 0.17 % of the refinery throughput . Portable gas leak imaging cameras are also a new technology that can be used to improve leak detection and repair , leading to reduced fugitive emissions .

Germany took interest in reducing its greenhouse gas ( GHG ) emissions by switching to renewable energy sources . Renewable energy use rose from 6.3 % in 2000 to 34 % in 2016 . Through the transition to renewable energy sources , Germany has become the climate change policy leader and renewable energy leader in the European Union ( EU ) and in the world with ambitious climate change programs . The current goal of the German government was approved on 14 November 2016 in the German Climate Action Plan 2050 , which outlines measures by which Germany can meet its greenhouse gas emissions by 2050 . By 2050 , Germany wants to reduce their GHGs by 80 to 95 % and by 2030 they want to reduce it by 55 % , compared to the EU target of 40 % . In order to achieve these goals , a variety of strategies and policies are used rather than legislation . The four strategies the German government bases air pollution control on are laying down environmental quality standards , emission reduction requirements according to the best available technology , production regulations , and laying down emission ceilings . Through these strategies , policy instruments have been put in place that have contributed to the success of the significant air pollution reduction in Germany . These instruments include the Federal Emission Control Act and Implementing Ordinances , Technical Instructions on Air Quality Control ( TA Luft ) , Amendment to Ordinance on Small Firing Installations , Implementation of the directive on industrial emissions , and Transboundary air pollution control policy . The German Feed-in-Tariff policy introduced in 2000 led to the significant increase in renewable energy use and decreasing air pollution . They have been introduced in Germany to increase the use of renewables , such as wind power , biomass , hydropower , geothermal power , and photovoltaics , thereby reducing GHG emissions causing air pollution and combating climate change .

However , national and global climate policies have become a top priority since the conservative-social democratic government came into power in 2005 , pushing both European and international climate negotiations . Positive path dependency in Germany 's climate and energy policies has occurred over the past 20 years . There are three main triggers that put Germany on this positive path dependency and what led them to becoming a climate change policy leader . The first being the widespread damages to health , due to smog , and to nature , due to acid rain , caused by air pollution . The second being the shock of the two oil price crises , in 1973 and 1979 , that highlighted the problem of the German economy 's strong dependence on unsure foreign sources .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation . In some areas , policies designed to address global warming may contribute positively towards other development objectives . In other areas , the cost of global warming policies may divert resources away from other socially and environmentally beneficial investments ( the opportunity costs of climate change policy ) .", "qid": "539", "docid": "Economics_of_global_warming", "rank": 94, "score": 101892 }, { "content": "Title: Hagedorn temperature Content: The Hagedorn temperature is the temperature in theoretical physics where hadronic matter ( i.e. ordinary matter ) is no longer stable , and must either `` evaporate '' or convert into quark matter ; as such , it can be thought of as the `` boiling point '' of hadronic matter . The Hagedorn temperature exists because the amount of energy available is high enough that matter particle ( quark-antiquark ) pairs can be spontaneously pulled from vacuum . Thus , naively considered , a system at Hagedorn temperature can accommodate as much energy as one can put in , because the formed quarks provide new degrees of freedom , and thus the Hagedorn temperature would be an impassable absolute hot . However , if this phase is viewed as quarks instead , it becomes apparent that the matter has transformed into quark matter , which can be further heated . It is about the same as the mass-energy of the lightest hadrons , the pion , at 130-140 MeV per particle or about 2 × 1012 K . This energy range can be routinely probed in particle accelerators such as CERN 's Large Hadron Collider . Matter at Hagedorn temperature or above will spew out fireballs of new particles , which can again produce new fireballs , and the ejected particles can then be detected by particle detectors . This quark matter has been detected in heavy-ion collisions at SPS and LHC in CERN ( France and Switzerland ) and at RHIC in Brookhaven National Laboratory ( USA ) .

It appears to be the second major hyperthermal that punctuated the long-term warming trend from the Late Paleocene through the early Eocene ( 58 to 50 Ma ) . The hyperthermals were geologically brief time intervals ( < 200,000 years ) of global warming and massive carbon input . The most extreme and best-studied event , the Paleocene-Eocene Thermal Maximum ( PETM or ETM-1 ) , occurred about 1.8 million years before ETM-2 , at approximately 55.5 Ma . Other hyperthermals likely followed ETM-2 at nominally 53.6 Ma ( H-2 ) , 53.3 ( I-1 ) , 53.2 ( I-2 ) and 52.8 Ma ( informally called K , X or ETM-3 ) . The number , nomenclature , absolute ages and relative global impact of the Eocene hyperthermals are the source of much current research . In any case , the hyperthermals appear to have ushered in the Early Eocene Climatic Optimum , the warmest interval of the Cenozoic Era . They also definitely precede the Azolla event at about 49 Ma . ETM-2 is clearly recognized in sediment sequences by analyzing the stable carbon isotope composition of carbon-bearing material . The 13C/12C ratio of calcium carbonate or organic matter drops significantly across the event . This is similar to what happens when one examines sediment across the PETM , although the magnitude of the negative carbon isotope excursion is not as large . The timing of Earth system perturbations during ETM-2 and the PETM also appear different . Specifically , the onset of ETM-2 may have been longer ( perhaps 30,000 years ) while the recovery seems to have been shorter ( perhaps < 50,000 years ) . ( Note , however , that the timing of short-term carbon cycle perturbations during both events remains difficult to constrain ) . A thin clay-rich horizon marks ETM-2 in marine sediment from widely separated locations . In sections recovered from the deep-sea ( for example those recovered by Ocean Drilling Program Leg 208 on Walvis Ridge ) , this layer is caused by dissolution of calcium carbonate . However , in sections deposited along continental margins ( for example those now exposed along the Clarence River , New Zealand ) , the clay-rich horizon represents dilution by excess accumulation of terrestrial material entering into the ocean . Similar changes in sediment accumulation are found across the PETM . In sediment from Lomonosov Ridge in the Arctic Ocean , intervals across both ETM-2 and the PETM shows signs of higher temperature , lower salinity and lower dissolved oxygen . The PETM and ETM-2 are thought to have a similar generic origin , although this idea is at the edge of current research . During both events , a tremendous amount of 13C-depleted carbon rapidly entered the ocean and atmosphere . This decreased the 13C/12C ratio of carbon-bearing sedimentary components , and dissolved carbonate in the deep ocean . Somehow the carbon input was coupled to an increase in Earth surface temperature and a greater seasonality in precipitation , which explains the excess terrestrial sediment discharge along continental margins . Possible explanations for changes during ETM-2 are the same as those for the PETM , and are discussed under the latter entry . The H-2 event appears to be a `` minor '' hyperthermal that follows ETM-2 ( H-1 ) by about 100,000 years . This has led to speculation that the two events are somehow coupled and paced by changes in orbital eccentricity . As in the case of the PETM , reversible dwarfing of mammals has been noted during the ETM-2 .", "qid": "540", "docid": "Eocene_Thermal_Maximum_2", "rank": 29, "score": 80317 }, { "content": "Title: 2013 heatwave in Ireland and the United Kingdom Content: The 2013 heat wave in the United Kingdom and Ireland was a period of unusually hot weather primarily in July 2013 , with isolated warm days in June and August .

It was launched in 2005 to fight Global warming and is a major pillar of EU climate policy . As of 2013 , the EU ETS covers more than 11,000 factories , power stations , and other installations with a net heat excess of 20 MW in 31 countries -- all 28 EU member states plus Iceland , Norway , and Liechtenstein . In 2008 , the installations regulated by the EU ETS were collectively responsible for close to half of the EU 's anthropogenic emissions of CO2 and 40 % of its total greenhouse gas emissions . Under the ` cap and trade ' principle , a maximum ( cap ) is set on the total amount of greenhouse gases that can be emitted by all participating installations . ` Allowances ' for emissions are then auctioned off or allocated for free , and can subsequently be traded . Installations must monitor and report their CO2 emissions , ensuring they hand in enough allowances to the authorities to cover their emissions . If emission exceeds what is permitted by its allowances , an installation must purchase allowances from others . Conversely , if an installation has performed well at reducing its emissions , it can sell its leftover credits . This allows the system to find the most cost-effective ways of reducing emissions without significant government intervention . The scheme has been divided into a number of `` trading periods '' . The first ETS trading period lasted three years , from January 2005 to December 2007 . The second trading period ran from January 2008 until December 2012 , coinciding with the first commitment period of the Kyoto Protocol . The third trading period began in January 2013 and will span until December 2020 . Compared to 2005 , when the EU ETS was first implemented , the proposed caps for 2020 represents a 21 % reduction of greenhouse gases . This target has been reached 6 years early as emissions in the ETS fell to 1812 mln tonnes in 2014 . The EU ETS has seen a number of significant changes , with the first trading period described as a ` learning by doing ' phase . Phase III sees a turn to auctioning a majority of permits rather than allocating freely ; harmonisation of rules for the remaining allocations ; and the inclusion of other greenhouse gases , such as nitrous oxide and perfluorocarbons . In 2012 , the EU ETS was also extended to the airline industry , though this has been paused for one year given the possibility of a global system for these emissions . The price of EU ETS carbon credits has been lower than intended , with a large surplus of allowances , in part because of the impact of the recent economic crisis on demand . In 2012 , the Commission said it would delay the auctioning of some allowances . Currently legislation is under way which would introduce a Market Stability Reserve to the EU ETS that adjusts the annual supply of CO2 permits based on the CO2 permits in circulation . Overall , since its conception , the EU ETS has been characterized by relatively high levels of policy uncertainty . This uncertainty has been both technical , in terms of its detailed rules and procedures , and political , in terms of its public , industry , and governmental support .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years . Global temperatures increased by 5 -- 8 ° C . The carbon dioxide was likely released in two pulses , the first lasting less than 2,000 years . Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon . Stratigraphic sections of rock from this period reveal numerous other changes . Fossil records for many organisms show major turnovers . For example , in the marine realm , a mass extinction of benthic foraminifera , a global expansion of subtropical dinoflagellates , and an appearance of excursion , planktic foraminifera and calcareous nanofossils all occurred during the beginning stages of PETM . On land , modern mammal orders ( including primates ) suddenly appear in Europe and in North America . Sediment deposition changed significantly at many outcrops and in many drill cores spanning this time interval .

On Earth , the main jet streams are located near the altitude of the tropopause and are westerly winds ( flowing west to east ) . Their paths typically have a meandering shape . Jet streams may start , stop , split into two or more parts , combine into one stream , or flow in various directions including opposite to the direction of the remainder of the jet . The strongest jet streams are the polar jets , at 9 - above sea level , and the higher altitude and somewhat weaker subtropical jets at 10 - . The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet . The northern hemisphere polar jet flows over the middle to northern latitudes of North America , Europe , and Asia and their intervening oceans , while the southern hemisphere polar jet mostly circles Antarctica all year round . Jet streams are the product of two factors : the atmospheric heating by solar radiation that produces the large scale Polar , Ferrel , and Hadley circulation cells , and the action of the Coriolis force acting on those moving masses . The Coriolis force is caused by the planet 's rotation on its axis . On other planets , internal heat rather than solar heating drives their jet streams . The Polar jet stream forms near the interface of the Polar and Ferrel circulation cells ; while the subtropical jet forms near the boundary of the Ferrel and Hadley circulation cells . Other jet streams also exist . During the Northern Hemisphere summer , easterly jets can form in tropical regions , typically where dry air encounters more humid air at high altitudes . Low-level jets also are typical of various regions such as the central United States . Meteorologists use the location of some of the jet streams as an aid in weather forecasting . The main commercial relevance of the jet streams is in air travel , as flight time can be dramatically affected by either flying with the flow or against , which results in significant fuel and time cost savings for airlines . Often , the airlines work to fly ` with ' the jet stream for this reason . Dynamic North Atlantic Tracks are one example of how airlines and air traffic control work together to accommodate the jet steam and winds aloft that results in the maximum benefit for airlines and other users . Clear-air turbulence , a potential hazard to aircraft passenger safety , is often found in a jet stream 's vicinity , but it does not create a substantial alteration on flight times .", "qid": "548", "docid": "Jet_stream", "rank": 2, "score": 127760 }, { "content": "Title: Rear-inflow jet Content: The rear-inflow jet is a component of bow echoes in a mesoscale convective system that aids in creating a stronger cold pool and downdraft . The jet forms as a response to a convective circulation having upshear tilt and horizontal pressure gradients . The cold pool that comes from the outflow of a storm forms an area of high pressure at the surface . In response to the surface high and warmer temperatures aloft due to convection , a mid-level mesolow forms behind the leading edge of the storm . With a mid-level area of low pressure , air is drawn in under the trailing stratiform region of precipitation . As air is drawn in on the rear side of the storm , it begins to descend as it approaches the front line of the cells . Before the reaching the leading edge , the jet dives heads to the ground as a strong downdraft , creating straight-line winds . Any mature mesoscale convective system is capable of developing its own rear-inflow jet , but questions remain as to what influences the strength of the jet . While the diabatic effects of sublimation , melting and evaporation play a role in influencing jet strength , these effects do not account for cases with strong rear-inflow jets . However , the diabatic effects are responsible for the jet subsiding behind the leading edge of the MCS . The sinking of the jet first starts when the mid level inflow goes under the trailing stratiform cloud before descending to the melting layer . There are other factors that contribute to the strength of any rear inflow jet . The strength of a rear inflow jet can be greatly increased with induced vortices at the end of the line , called `` line-end vortices '' or `` book-end vortices . '' These vortices at either end of the line will help reinforce the rear inflow towards the center of the line . The other factor that can help strengthen the jet is an environment in which the large scale flow is feeding/forcing mid-level air into the rear end of the storm .", "qid": "548", "docid": "Rear-inflow_jet", "rank": 3, "score": 126983 }, { "content": "Title: Mountain jet Content: Mountain jets are a type of jet stream created by surface winds channeled through mountain passes , sometimes causing high wind speeds and drastic temperature changes .", "qid": "548", "docid": "Mountain_jet", "rank": 4, "score": 122581 }, { "content": "Title: Pacific–North American teleconnection pattern Content: The Pacific -- North American teleconnection pattern ( PNA ) is a climatological term for a large-scale weather pattern with two modes , denoted positive and negative , and which relates the atmospheric circulation pattern over the North Pacific Ocean with the one over the North American continent .

The PNA pattern is associated with strong fluctuations in the strength and location of the East Asian jet stream . The positive phase is associated with an enhanced East Asian jet stream and with an eastward shift in the jet exit region toward the western United States .

It is the primary physical mechanism for the jet stream and plays an important role in other large-scale atmospheric phenomena . The thermal wind ensures the jet stream is typically strongest in the upper half of the troposphere , which is the atmospheric layer extending from the surface of the planet up to a height of 12 km to 15 km . Mathematically , the thermal wind relation defines a vertical wind shear -- a variation in wind speed or direction with height . The wind shear in this case is a function of a horizontal temperature gradient , which is a variation in temperature over some horizontal distance . Also called baroclinic flow , the thermal wind varies with height in proportion to the horizontal temperature gradient . The thermal wind relation results from hydrostatic balance and geostrophic balance in the presence of a temperature gradient along constant pressure surfaces , or isobars . The term thermal wind is often considered a misnomer , since it really describes the change in wind with height , rather the wind itself . However , one can view the thermal wind as a geostrophic wind that varies with height , so that the term wind seems appropriate . In the early years of meteorology , when data was scarce , the wind field could be estimated using the thermal wind relation and knowledge of a surface wind speed and direction as well as thermodynamic soundings aloft . In this way , the thermal wind relation acts to define the wind itself , rather than just its shear .

Initially , a high-pressure system moves poleward of a north-south mountain range . Once it sloshes over poleward and eastward of the range , the flow around the high banks up against the mountains , forming a barrier jet which funnels cool air down a stretch of land east of the mountains . The higher the mountain chain , the deeper the cold air mass becomes lodged to its east , and the greater impediment it is within the flow pattern and the more resistant it becomes to intrusions of milder air . As the equatorward portion of the system approaches the cold air wedge , persistent low cloudiness , such as stratus , and precipitation such as drizzle develop , which can linger for long periods of time ; as long as ten days . The precipitation itself can create or enhance a damming signature , if the poleward high is relatively weak . If such events accelerate through mountain passes , dangerously accelerated mountain-gap winds can result , such as the Tehuantepecer and Santa Ana winds .

The AO is believed by climatologists to be causally related to , and thus partially predictive of , weather patterns in locations many thousands of miles away , including many of the major population centers of Europe and North America . NASA climatologist Dr. James E. Hansen explained the mechanism by which the AO affects weather at points so distant from the Arctic , as follows : `` The degree to which Arctic air penetrates into middle latitudes is related to the AO index , which is defined by surface atmospheric pressure patterns . When the AO index is positive , surface pressure is low in the polar region . This helps the middle latitude jet stream to blow strongly and consistently from west to east , thus keeping cold Arctic air locked in the polar region . When the AO index is negative , there tends to be high pressure in the polar region , weaker zonal winds , and greater movement of frigid polar air into middle latitudes . '' This zonally symmetric seesaw between sea level pressures in polar and temperate latitudes was first identified by Edward Lorenz and named in 1998 by David W.J. Thompson and John Michael Wallace . The North Atlantic oscillation ( NAO ) is a close relative of the AO and there exist arguments about whether one or the other is more fundamentally representative of the atmosphere 's dynamics ; Ambaum et al. argue that the NAO can be identified in a more physically meaningful way . Over most of the past century , the Arctic Oscillation alternated between its positive and negative phases . Starting in the 1970s the oscillation has trended to more of a positive phase when averaged using a 60-day running mean , though it has trended to a more neutral state in the last decade . The oscillation still fluctuates stochastically between negative and positive values on daily , monthly , seasonal and annual time scales , although , despite its stochastic nature , meteorologists have attained high levels of predictive accuracy in recent times , at least for the shorter term forecasts . ( The correlation between actual observations and the 7-day mean GFS ensemble AO forecasts is approximately 0.9 , a figure at the high end for that statistic . ) The National Snow and Ice Data Center describes the effects of the AO in some detail : `` In the positive phase , higher pressure at midlatitudes drives ocean storms farther north , and changes in the circulation pattern bring wetter weather to Alaska , Scotland and Scandinavia , as well as drier conditions to the western United States and the Mediterranean . In the positive phase , frigid winter air does not extend as far into the middle of North America as it would during the negative phase of the oscillation . This keeps much of the United States east of the Rocky Mountains warmer than normal , but leaves Greenland and Newfoundland colder than usual . Weather patterns in the negative phase are in general `` opposite '' to those of the positive phase . '' Climatologists are now routinely invoking the Arctic Oscillation in their official public explanations for extremes of weather . The following statement from the National Oceanic and Atmospheric Administration 's National Climatic Data Center : State of the Climate December 2010 which uses the phrase `` negative Arctic Oscillation '' four times , is very representative of this increasing tendency : `` Cold arctic air gripped western Europe in the first three weeks of December . Two major snowstorms , icy conditions , and frigid temperatures wreaked havoc across much of the region ... The harsh winter weather was attributed to a negative Arctic Oscillation , which is a climate pattern that influences weather in the Northern Hemisphere . A very persistent , strong ridge of high pressure , or ` blocking system ' , near Greenland allowed cold Arctic air to slide south into Europe . Europe was not the only region in the Northern Hemisphere affected by the Arctic Oscillation . A large snow storm and frigid temperatures affected much of the Midwest United States on December 10 -- 13 ... '' A further , quite graphic illustration of the effects of the negative phase of the oscillation occurred in February 2010 . In that month , the Arctic Oscillation reached its most negative monthly mean value , − 4.266 , in the entire post-1950 era ( the period of accurate record-keeping ) . That month was characterized by three separate historic snowstorms that occurred in the mid-Atlantic region of the United States . The first storm dumped 25 in on Baltimore , Maryland , on February 5 -- 6 , and then a second storm dumped 19.5 in on February 9 -- 10 . In New York City , a separate storm deposited 20.9 in on February 25 -- 26 . This kind of snowstorm activity is as anomalous and extreme as the negative AO value itself . Similarly , the greatest negative value for the AO since 1950 in January was − 3.767 in 1977 , which coincided with the coldest mean January temperature in New York City , Washington , D.C. , Baltimore , and many other mid-Atlantic locations in that span of time . And though the January AO has been negative only 60.6 % of the time between 1950 and 2010 , 9 of the 10 coldest Januarys in New York City since 1950 have coincided with negative AOs . However , the correlation between sharply negative Arctic Oscillations and excessive winter cold and snow in regions vulnerable in that way to these negative AOs should not be overstated . It is by no means a simple , one-to-one equivalence . An extreme Arctic Oscillation does not necessarily mean extreme weather will occur . For example , since 1950 , eight out of the 10 coldest Januarys in New York did not coincide with the 10 lowest January AO values . And the fourth warmest January there since 1950 coincided with one of those 10 most negative AOs . So , although many climatologists believe that the Arctic Oscillation affects the probability of certain weather events occurring in certain places , the heightened chance of a phenomenon by no means assures it , nor does the lessened likelihood exclude it . Further , the precise value of the AO index only imperfectly reflects the severity of the weather associated with it .", "qid": "548", "docid": "Arctic_oscillation", "rank": 16, "score": 105821 }, { "content": "Title: Wasaburo Oishi Content: was a Japanese meteorologist .

This turbulence includes various components , the most important of which are wingtip vortices and jetwash . Jetwash refers simply to the rapidly moving gases expelled from a jet engine ; it is extremely turbulent , but of short duration . Wingtip vortices , on the other hand , are much more stable and can remain in the air for up to three minutes after the passage of an aircraft . Wingtip vortices occur when a wing is generating lift . Air from below the wing is drawn around the wingtip into the region above the wing by the lower pressure above the wing , causing a vortex to trail from each wingtip . Wake turbulence exists in the vortex flow behind the wing . The strength of wingtip vortices is determined primarily by the weight and airspeed of the aircraft . Wingtip vortices make up the primary and most dangerous component of wake turbulence . Lift is generated by high pressure below the wing and low pressure above the wing . As the high-pressure air moves around the wingtip to the low-pressure regions ( since the gradient is always from high to low pressure ) , the air rotates , or creates a horizontal `` tornado '' behind the wings . This tornado sinks lower and lower until it dissipates . Wake turbulence is especially hazardous in the region behind an aircraft in the takeoff or landing phases of flight . During take-off and landing , aircraft operate at high angle of attack . This flight attitude maximizes the formation of strong vortices .

Most weather phenomena occur in the lowest level of the atmosphere , the troposphere , just below the stratosphere . Weather refers to day-to-day temperature and precipitation activity , whereas climate is the term for the averaging of atmospheric conditions over longer periods of time . When used without qualification , `` weather '' is generally understood to mean the weather of Earth . Weather is driven by air pressure , temperature and moisture differences between one place and another . These differences can occur due to the sun 's angle at any particular spot , which varies with latitude . The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations : the Hadley Cell , the Ferrel Cell , the Polar Cell , and the jet stream . Weather systems in the mid-latitudes , such as extratropical cyclones , are caused by instabilities of the jet stream flow . Because the Earth 's axis is tilted relative to its orbital plane , sunlight is incident at different angles at different times of the year . On Earth 's surface , temperatures usually range ± 40 ° C ( − 40 ° F to 100 ° F ) annually . Over thousands of years , changes in Earth 's orbit can affect the amount and distribution of solar energy received by the Earth , thus influencing long-term climate and global climate change . Surface temperature differences in turn cause pressure differences . Higher altitudes are cooler than lower altitudes as most atmospheric heating is due to contact with the Earth 's surface while radiative losses to space are mostly constant . Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location . The Earth 's weather system is a chaotic system ; as a result , small changes to one part of the system can grow to have large effects on the system as a whole . Human attempts to control the weather have occurred throughout history , and there is evidence that human activities such as agriculture and industry have modified weather patterns . Studying how the weather works on other planets has been helpful in understanding how weather works on Earth . A famous landmark in the Solar System , Jupiter 's Great Red Spot , is an anticyclonic storm known to have existed for at least 300 years . However , weather is not limited to planetary bodies .

Flow-control structures are known to have existed for thousands of years . Some built by the Chinese have been in continuous use for over 2,000 years . The Chinese used these structures to divert water to irrigate fields and to actually deposit silt in specific areas so that the channels were not blocked by silt build-up . Structures like this required yearly maintenance to remove the accumulated silt . More modern structures add to these basic principles . In Hawaii , there are numerous flow-control structures that have been built to irrigate the pineapple and sugar cane fields . The purpose of these structures is to divert water into the various canals and to keep them full . When over full , they dump excess water back into either streams or other canals .

The ramp sits at an acute angle to deflect the intake air from the longitudinal direction . At supersonic flight speeds , the deflection of the air stream creates a number of oblique shock waves at each change of gradient along at the ramp . Air crossing each shock wave suddenly slows to a lower Mach number , thus increasing pressure . Ideally , the first oblique shock wave should intercept the air intake lip , thus avoiding air spillage and pre-entry drag on the outer boundary of the deflected streamtube . For a fixed geometry intake at zero incidence , this condition can only be achieved at one particular flight Mach number , because the angle of the shock wave ( to the longitudinal direction ) becomes more acute with increasing aircraft speed . More advanced supersonic intakes feature a ramp with a number of discrete changes of gradient in order to generate multiple oblique shock waves . In the case of Concorde , the first ( converging ) intake ramp is followed by a diverging ramp . After the air passes the end of the first ramp it has become subsonic such that the diverging ramp further contributes towards the reduction in airstream velocity and consequently its increase in pressure . This intake design thus ensures excellent pressure recovery and contributes to Concorde 's improved fuel efficiency whilst cruising supersonically at up to Mach 2.2 ( beyond which airframe heating effects limit any further increase in speed ) . For a fixed geometry it is feasible to use curved intakes without any shocks before the final normal shock . Modern fighter jets ( like the F-22 Raptor ) have engines so powerful that top speed is not limited by them , thus spillage at the intake is acceptable and a lightweight fixed geometry chosen . The nacelle has a round outer lip to deflect spillage back into the longitudinal direction . The nacelle thus gets a very large cross section with more volume than needed for the engine and in the F-22 the nacelles are combined with the fuselage to create a large weapon bay , place for fuel , and a wide body , which generates some lift . Modern jets have a horizontal ramp thus spillage at least produces some lift . In the case of the F-22 the inlet has two ramps placed in a diamond shape , thus for most Mach - and thrust-conditions spillage occurs only at the aft / lower corner of that diamond . In the case of the F-22 the leading edges of the wing become supersonic at Mach 1.8 and certainly are as large a source of wave drag as the inlet . Variable geometry intakes , such as those on Concorde , vary the ramp angle to focus the series of oblique shock waves onto the intake lip , control of which is accomplished by complex non-linear control laws using the ramp void pressure ( the pressure of the air in the gap between the two ramps ) as a control input .", "qid": "548", "docid": "Intake_ramp", "rank": 40, "score": 91538 }, { "content": "Title: Jet mill Content: A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other .

It is one of the earliest , if not the earliest motorized sufboard , produced from 1965 to 1968 . The original designer was a former engineer from Boeing Aircraft . It was designed to use an aircraft trim tab roller control with your foot for acceleration . There was a simple ingenious safety OFF switch , using a magnet that connected two electrical terminals across a point , located close by the engine 's surface watertight hatch . The rider would attach a strap to his ankle with a flexible wire line to the magnet . When he fell off , it would stop the engine . To start it , there was a flush submerged pull start handle in the top surface of the deck by the engine hatch . Air feed to the engine was controlled by a flapper valve vent forward on the nose of the board 's top surface . It sucked air in , porting it to the stern ( or rear ) of the craft . It was constructed of a heavy marine grade aircraft aluminum alloy to withstand the saltwater conditions it would be used in . The hull was self-bailing via a venturi effect off the grated forward water feed port , on the bottom of the board , that exhausted through the jet drive nozzle to rear for propulsion . It required routine maintenance to keep a tiny vent hole clear of seaweed or debris or the engine compartment would flood easily . This board was n't designed to be like a modern jet ski or later jet boards that were completely self-powered by much larger engines . The main design principal behind it was to aide a surfer in getting out through the waves , instead of laboriously paddling . This powered board also aided in times of smaller ocean waves to push them along or in order to catch faster waves without paddling . Steering was accomplished by moving your weight around on the board and leaning similar to any standard surfboard . But this board was no lightweight and carrying it any distance ( despite its flip out handle ) at 11 feet long and weighing 85 pounds , could be a real chore . Even with two people going to a remote access beach to launch it could be more work than paddling a normal board once in the water . In heavy wave action , you would not want this beast coming down on your head , if you fell off . So it was seldom used in rough water conditions for this reason . With its aluminum hull and unique flat lightweight custom Tehcumsuh 6.25-horsepower engine and its custom Phelon Ignition , this board was indeed fairly thin . It was , however , remarkably buoyant with only the engine compartment , air vent feed tube and jet tube to nozzle stern , not being filled with flotation foam . Being that this board was only around five inches thick , made it much more like its big log board , non-powered cousins . In the later model , this original engine was further modified for reliability . Originally designed from a custom single-cylinder chainsaw motor with custom water-cooled jacket design , fed by the venturi effect of the enclosed jet prop that also bailed engine compartment water out through the jet drive 's stern nozzle . This also carried the exhaust gases out the rear nozzle with a preventive flap to keep water from getting into the engine , when it was n't running . The early mock up hulls were made of wood , but later production hulls were made by the aeronautical company Sargent Fletcher in El Monte , California . They very expensive to build , being made of thick gauge form fabricated , marine grade alloy or modified aircraft aluminum ( like a plane wing or floats on float plane ) and were mostly made of custom parts . They were priced expensive because of this costly fabrication process and only saw limited manufacture of just over six hundred . Sales were mostly to elite surfers and the wealthy .

Because spacecraft only contain a finite amount of fuel and there is little chance to refill them , some alternative reaction control systems have been developed so that fuel can be conserved . For stationkeeping , some spacecraft ( particularly those in geosynchronous orbit ) use high-specific-impulse engines such as arcjets , ion thrusters , or Hall effect thrusters .

The jet winds travel southwest from the Caribbean and the Gulf of Mexico to the Pacific Ocean through a pass in the Cordillera mountains at Lake Nicaragua . The jet follows the same path as the northeast trade winds in this region ; however , due to a unique combination of synoptic scale meteorology and orographic phenomena , the jet winds can reach much greater speeds than their trade wind counterparts . That is to say , the winds occur when cold high-pressure systems from the North American continent meet warm moist air over the Caribbean and Gulf of Mexico , generating winds that are then funneled through a mountain pass in the Cordillera . The Papagayo jet is also not unique to this region . There are two other breaks in the Cordillera where this same phenomenon occurs , one at the Chivela Pass in México and another at the Panama Canal , producing the Tehuano ( Tehuantepecer ) and the Panama jets respectively . The Papagayo jet also induces mesoscale meteorology phenomena that influence the pacific waters hundreds of kilometers off the Nicaraguan and Costa Rican shores . When the jet wind surges , it creates cyclonic and anticyclonic eddies , Ekman transport , and upwelling that contribute to the creation of the Costa Rica Dome off the western coast of Central America in the Western Hemisphere Warm Pool ( WHWP ) .

Because they move northward from over or near the Gulf of Mexico , these storm systems are capable of transporting copious amounts of moisture with them . At their strongest , these storm systems are even more potent snowfall producers than panhandle hooks , primarily because of the mixing of Atlantic Ocean moisture into the storm system once they cross the Appalachian Mountains . Because of the general west to east movement of weather systems in the mid latitudes of the northern hemisphere , Gulf Lows rarely affect areas west of the Mississippi River . One such exception was the Halloween Blizzard of 1991 . There are two types of `` Gulf Lows '' : West and East Gulf Cyclones or Types Ga and Gb . As western storms ( Alberta , North and South Pacific and Rocky Mountain ) move eastward , a trailing frontal remnant is often left in the Gulf of Mexico or the adjacent coastal states . When the frontal trough from a new cyclone enters this area , cyclogenesis often occurs on the Gulf front . This newly formed Gulf wave that moves northeastward and dominates the weather over the eastern United States . One of the basic differences between the two types is that the Ga track is west of the Appalachians and the Gb track is east of the Appalachians . The Ga type is characterized by an upper level trough in the central and eastern part of the United States which steers the newly formed wave north and northeast over the western side of the Appalachians accompanied by widespread precipitation to the north . This type is most frequently observed in the winter and early spring .

The concept is from the Age of Sail , and is now largely antiquated . A ship at sea is said to possess the weather gage if it is in any position upwind of the other vessel . Close proximity with the land , tidal and stream effects , and wind variability due to geography ( hills , cliffs , etc. ) may also come into play . An upwind vessel is able to manoeuvre at will toward any downwind point , since in doing so the relative wind moves aft . A vessel downwind of another , however , in attempting to attack upwind , is constrained to trim sail as the relative wind moves forward and can not point too far into the wind for fear of being headed . In sailing warfare , when beating to windward , the vessel experiences heeling under the sideward pressure of the wind . This restricts gunnery , as cannon on the windward side are now elevated , while the leeward gun ports aim into the sea , or in heavy weather may be awash . A ship with the weather gage , turning downwind to attack , may alter course at will in order to bring starboard and port guns to appropriate elevations . Ships seeking to evade capture or attack , however , have the advantage being downwind if they are faster vessels or are close to friendly land . The term has had a literary rebirth in the popular seafaring novels of C.S. Forester , Patrick O'Brian , and Alexander Kent . One of the last times that weather gage was perhaps a factor in a naval engagement was in the Battle of the Denmark Strait in 1941 where the German battleship Bismarck and the heavy cruiser Prinz Eugen held the weather gage over the British battleship HMS Prince of Wales and the battlecruiser . Being upwind , the German ships had the advantage that their rangefinders were not as wet as the British rangefinders , which faced the spray direction . The weather restricted the visual range to much less than the gun range . In the end , being upwind from one 's target was not an advantage for the Germans -- it was even detrimental . The common tactic was to bypass the thick armor of a ship 's hull , making the shells dive almost vertically over the less-protected horizontal decks . Firing against the wind would make the shells fall more vertically , given their parabolic trajectories . The concept of weather gage is still useful in modern yacht racing , although it is hardly ever referred to by that name . The sails of a boat disrupt the wind to leeward ; this disruption is often called `` dirt '' or `` dirty air '' . An overtaking boat on a downwind course can position itself to focus its dirty air on the boat ahead of it .

On Earth , the main jet streams are located near the altitude of the tropopause and are westerly winds ( flowing west to east ) . Their paths typically have a meandering shape . Jet streams may start , stop , split into two or more parts , combine into one stream , or flow in various directions including opposite to the direction of the remainder of the jet . The strongest jet streams are the polar jets , at 9 - above sea level , and the higher altitude and somewhat weaker subtropical jets at 10 - . The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet . The northern hemisphere polar jet flows over the middle to northern latitudes of North America , Europe , and Asia and their intervening oceans , while the southern hemisphere polar jet mostly circles Antarctica all year round . Jet streams are the product of two factors : the atmospheric heating by solar radiation that produces the large scale Polar , Ferrel , and Hadley circulation cells , and the action of the Coriolis force acting on those moving masses . The Coriolis force is caused by the planet 's rotation on its axis . On other planets , internal heat rather than solar heating drives their jet streams . The Polar jet stream forms near the interface of the Polar and Ferrel circulation cells ; while the subtropical jet forms near the boundary of the Ferrel and Hadley circulation cells . Other jet streams also exist . During the Northern Hemisphere summer , easterly jets can form in tropical regions , typically where dry air encounters more humid air at high altitudes . Low-level jets also are typical of various regions such as the central United States . Meteorologists use the location of some of the jet streams as an aid in weather forecasting . The main commercial relevance of the jet streams is in air travel , as flight time can be dramatically affected by either flying with the flow or against , which results in significant fuel and time cost savings for airlines . Often , the airlines work to fly ` with ' the jet stream for this reason . Dynamic North Atlantic Tracks are one example of how airlines and air traffic control work together to accommodate the jet steam and winds aloft that results in the maximum benefit for airlines and other users .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

The jet forms as a response to a convective circulation having upshear tilt and horizontal pressure gradients . The cold pool that comes from the outflow of a storm forms an area of high pressure at the surface . In response to the surface high and warmer temperatures aloft due to convection , a mid-level mesolow forms behind the leading edge of the storm . With a mid-level area of low pressure , air is drawn in under the trailing stratiform region of precipitation . As air is drawn in on the rear side of the storm , it begins to descend as it approaches the front line of the cells . Before the reaching the leading edge , the jet dives heads to the ground as a strong downdraft , creating straight-line winds . Any mature mesoscale convective system is capable of developing its own rear-inflow jet , but questions remain as to what influences the strength of the jet . While the diabatic effects of sublimation , melting and evaporation play a role in influencing jet strength , these effects do not account for cases with strong rear-inflow jets . However , the diabatic effects are responsible for the jet subsiding behind the leading edge of the MCS . The sinking of the jet first starts when the mid level inflow goes under the trailing stratiform cloud before descending to the melting layer . There are other factors that contribute to the strength of any rear inflow jet . The strength of a rear inflow jet can be greatly increased with induced vortices at the end of the line , called `` line-end vortices '' or `` book-end vortices . '' These vortices at either end of the line will help reinforce the rear inflow towards the center of the line .

It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect .

Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world .

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) .

These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift .

It involves denial , dismissal , unwarranted doubt or contrarian views which strongly depart from the scientific opinion on climate change , including the extent to which it is caused by humans , its impacts on nature and human society , or the potential of adaptation to global warming by human actions . Some deniers do endorse the term , but others often prefer the term climate change skepticism , although this is a misnomer for those who deny anthropogenic global warming . In effect , the two terms form a continuous , overlapping range of views , and generally have the same characteristics : both reject , to a greater or lesser extent , mainstream scientific opinion on climate change . Climate change denial can also be implicit , when individuals or social groups accept the science but fail to come to terms with it or to translate their acceptance into action . Several social science studies have analyzed these positions as forms of denialism . Campaigning to undermine public trust in climate science has been described as a `` denial machine '' of industrial , political and ideological interests , supported by conservative media and skeptical bloggers in manufacturing uncertainty about global warming . In the public debate , phrases such as climate skepticism have frequently been used with the same meaning as climate denialism . The labels are contested : those actively challenging climate science commonly describe themselves as `` skeptics '' , but many do not comply with common standards of scientific skepticism and , regardless of evidence , persistently deny the validity of human caused global warming . Although scientific opinion on climate change is that human activity is extremely likely to be the primary driver of climate change , the politics of global warming have been affected by climate change denial , hindering efforts to prevent climate change and adapt to the warming climate . Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none . Of the world 's countries , the climate change denial industry is most powerful in the United States . Since January 2015 , the United States Senate Committee on Environment and Public Works has been chaired by oil lobbyist and climate change denier Jim Inhofe . Inhofe is notorious for having called climate change `` the greatest hoax ever perpetrated against the American people '' and for having claimed to have debunked the alleged hoax in February 2015 when he brought a snowball with him in the Senate chamber and tossed it across the floor . Organised campaigning to undermine public trust in climate science is associated with conservative economic policies and backed by industrial interests opposed to the regulation of emissions . Climate change denial has been associated with the fossil fuels lobby , the Koch brothers , industry advocates and libertarian think tanks , often in the United States . More than 90 % of papers sceptical on climate change originate from right-wing think tanks . The total annual income of these climate change counter-movement-organizations is roughly $ 900 million . Between 2002 and 2010 , nearly $ 120 million ( # 77 million ) was anonymously donated via the Donors Trust and Donors Capital Fund to more than 100 organisations seeking to undermine the public perception of the science on climate change . In 2013 the Center for Media and Democracy reported that the State Policy Network ( SPN ) , an umbrella group of 64 U.S. think tanks , had been lobbying on behalf of major corporations and conservative donors to oppose climate change regulation . Since the late 1970s , oil companies have published research broadly in line with the standard views on global warming .

The report discusses the effect of global warming on the world economy . Although not the first economic report on climate change , it is significant as the largest and most widely known and discussed report of its kind . The Review states that climate change is the greatest and widest-ranging market failure ever seen , presenting a unique challenge for economics . The Review provides prescriptions including environmental taxes to minimise the economic and social disruptions . The Stern Review 's main conclusion is that the benefits of strong , early action on climate change far outweigh the costs of not acting . The Review points to the potential impacts of climate change on water resources , food production , health , and the environment . According to the Review , without action , the overall costs of climate change will be equivalent to losing at least 5 % of global gross domestic product ( GDP ) each year , now and forever . Including a wider range of risks and impacts could increase this to 20 % of GDP or more , also indefinitely . Stern believes that 5 -- 6 degrees of temperature increase is `` a real possibility . '' The Review proposes that one percent of global GDP per annum is required to be invested to avoid the worst effects of climate change . In June 2008 , Stern increased the estimate for the annual cost of achieving stabilisation between 500 and 550 ppm CO2e to 2 % of GDP to account for faster than expected climate change .

On Earth , the main jet streams are located near the altitude of the tropopause and are westerly winds ( flowing west to east ) . Their paths typically have a meandering shape . Jet streams may start , stop , split into two or more parts , combine into one stream , or flow in various directions including opposite to the direction of the remainder of the jet . The strongest jet streams are the polar jets , at 9 - above sea level , and the higher altitude and somewhat weaker subtropical jets at 10 - . The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet . The northern hemisphere polar jet flows over the middle to northern latitudes of North America , Europe , and Asia and their intervening oceans , while the southern hemisphere polar jet mostly circles Antarctica all year round . Jet streams are the product of two factors : the atmospheric heating by solar radiation that produces the large scale Polar , Ferrel , and Hadley circulation cells , and the action of the Coriolis force acting on those moving masses . The Coriolis force is caused by the planet 's rotation on its axis . On other planets , internal heat rather than solar heating drives their jet streams . The Polar jet stream forms near the interface of the Polar and Ferrel circulation cells ; while the subtropical jet forms near the boundary of the Ferrel and Hadley circulation cells . Other jet streams also exist . During the Northern Hemisphere summer , easterly jets can form in tropical regions , typically where dry air encounters more humid air at high altitudes . Low-level jets also are typical of various regions such as the central United States . Meteorologists use the location of some of the jet streams as an aid in weather forecasting .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions . They were preserved so well by quick freezing , which is taken as evidence of a rapid onset of a global blizzard or similar event . Interspersed with the analytical parts of the book are a series of interlinked short fictional scenarios , written in italics , describing what might transpire today if a destabilization of the North Atlantic Current were to occur . The fictional accounts of `` current events '' as the meteorological situation deteriorates provided background and inspiration for the 2004 science fiction film The Day After Tomorrow .

The AO is believed by climatologists to be causally related to , and thus partially predictive of , weather patterns in locations many thousands of miles away , including many of the major population centers of Europe and North America . NASA climatologist Dr. James E. Hansen explained the mechanism by which the AO affects weather at points so distant from the Arctic , as follows : `` The degree to which Arctic air penetrates into middle latitudes is related to the AO index , which is defined by surface atmospheric pressure patterns . When the AO index is positive , surface pressure is low in the polar region . This helps the middle latitude jet stream to blow strongly and consistently from west to east , thus keeping cold Arctic air locked in the polar region . When the AO index is negative , there tends to be high pressure in the polar region , weaker zonal winds , and greater movement of frigid polar air into middle latitudes . '' This zonally symmetric seesaw between sea level pressures in polar and temperate latitudes was first identified by Edward Lorenz and named in 1998 by David W.J. Thompson and John Michael Wallace . The North Atlantic oscillation ( NAO ) is a close relative of the AO and there exist arguments about whether one or the other is more fundamentally representative of the atmosphere 's dynamics ; Ambaum et al. argue that the NAO can be identified in a more physically meaningful way . Over most of the past century , the Arctic Oscillation alternated between its positive and negative phases . Starting in the 1970s the oscillation has trended to more of a positive phase when averaged using a 60-day running mean , though it has trended to a more neutral state in the last decade . The oscillation still fluctuates stochastically between negative and positive values on daily , monthly , seasonal and annual time scales , although , despite its stochastic nature , meteorologists have attained high levels of predictive accuracy in recent times , at least for the shorter term forecasts . ( The correlation between actual observations and the 7-day mean GFS ensemble AO forecasts is approximately 0.9 , a figure at the high end for that statistic . ) The National Snow and Ice Data Center describes the effects of the AO in some detail : `` In the positive phase , higher pressure at midlatitudes drives ocean storms farther north , and changes in the circulation pattern bring wetter weather to Alaska , Scotland and Scandinavia , as well as drier conditions to the western United States and the Mediterranean . In the positive phase , frigid winter air does not extend as far into the middle of North America as it would during the negative phase of the oscillation . This keeps much of the United States east of the Rocky Mountains warmer than normal , but leaves Greenland and Newfoundland colder than usual . Weather patterns in the negative phase are in general `` opposite '' to those of the positive phase . '' Climatologists are now routinely invoking the Arctic Oscillation in their official public explanations for extremes of weather . The following statement from the National Oceanic and Atmospheric Administration 's National Climatic Data Center : State of the Climate December 2010 which uses the phrase `` negative Arctic Oscillation '' four times , is very representative of this increasing tendency : `` Cold arctic air gripped western Europe in the first three weeks of December . Two major snowstorms , icy conditions , and frigid temperatures wreaked havoc across much of the region ... The harsh winter weather was attributed to a negative Arctic Oscillation , which is a climate pattern that influences weather in the Northern Hemisphere . A very persistent , strong ridge of high pressure , or ` blocking system ' , near Greenland allowed cold Arctic air to slide south into Europe . Europe was not the only region in the Northern Hemisphere affected by the Arctic Oscillation . A large snow storm and frigid temperatures affected much of the Midwest United States on December 10 -- 13 ... '' A further , quite graphic illustration of the effects of the negative phase of the oscillation occurred in February 2010 . In that month , the Arctic Oscillation reached its most negative monthly mean value , − 4.266 , in the entire post-1950 era ( the period of accurate record-keeping ) . That month was characterized by three separate historic snowstorms that occurred in the mid-Atlantic region of the United States . The first storm dumped 25 in on Baltimore , Maryland , on February 5 -- 6 , and then a second storm dumped 19.5 in on February 9 -- 10 . In New York City , a separate storm deposited 20.9 in on February 25 -- 26 . This kind of snowstorm activity is as anomalous and extreme as the negative AO value itself . Similarly , the greatest negative value for the AO since 1950 in January was − 3.767 in 1977 , which coincided with the coldest mean January temperature in New York City , Washington , D.C. , Baltimore , and many other mid-Atlantic locations in that span of time . And though the January AO has been negative only 60.6 % of the time between 1950 and 2010 , 9 of the 10 coldest Januarys in New York City since 1950 have coincided with negative AOs . However , the correlation between sharply negative Arctic Oscillations and excessive winter cold and snow in regions vulnerable in that way to these negative AOs should not be overstated . It is by no means a simple , one-to-one equivalence . An extreme Arctic Oscillation does not necessarily mean extreme weather will occur . For example , since 1950 , eight out of the 10 coldest Januarys in New York did not coincide with the 10 lowest January AO values . And the fourth warmest January there since 1950 coincided with one of those 10 most negative AOs . So , although many climatologists believe that the Arctic Oscillation affects the probability of certain weather events occurring in certain places , the heightened chance of a phenomenon by no means assures it , nor does the lessened likelihood exclude it . Further , the precise value of the AO index only imperfectly reflects the severity of the weather associated with it .", "qid": "550", "docid": "Arctic_oscillation", "rank": 8, "score": 109190 }, { "content": "Title: John H.

Mercer ( Cheltenham , England , 19 October 1922 -- Columbus , Ohio 3 July 1987 ) was a glaciologist , chiefly known for his theoretical work on , and field studies of Antarctic ice streams , especially in the Transantarctic Mountains and in West Antarctica . Following John T. Hollin 's work ( 1962 ) suggesting that climatic warming and rising sea-level cause Antarctic ice shelves to retreat , Mercer postulated that the West Antarctic ice sheet , being grounded well below sea-level and terminating in floating ice shelves , was vulnerable to these changes and may have collapsed altogether during the last interglacial when Antarctica may have been warmer and sea-level may have been higher . In 1978 , in the science magazine Nature , Mercer pointed out that `` green-house '' warming from burning fossil fuel could have the same effect during the present interglacial . Two studies published 12 May 2014 confirm Mercer 's assumption . Climate scientist James Hansen has coined the term , `` John Mercer effect . '' After Mercer published his paper suggesting that the West Antarctic ice sheet could collapse in response to warming , he struggled to get funding . Others , including Hansen , had similar problems . Many climate scientists censor their own work to avoid losing funding , especially regarding prospects for limiting warming to 2 ° C above pre-industrial temperatures . John H. Mercer was the third child of Harriet and John W. Mercer . He was educated at private schools in Cheltenham and , later , at Gordonstoun in Scotland . During World War II he served in the British Merchant Marines ( 1940 -- 46 ) as a radio man . After the war he went to University of Cambridge and studied geography . At that time he came under the influence of William Vaughan Lewis . After finishing his B.A. in 1949 Mercer went to Canada , where he received his PhD in geography from McGill University in 1954 . He was a Research Scholar from 1954 to 1956 at the Australian National University in Canberra , where he studied land use and population in western Samoa .

The jet forms as a response to a convective circulation having upshear tilt and horizontal pressure gradients . The cold pool that comes from the outflow of a storm forms an area of high pressure at the surface . In response to the surface high and warmer temperatures aloft due to convection , a mid-level mesolow forms behind the leading edge of the storm . With a mid-level area of low pressure , air is drawn in under the trailing stratiform region of precipitation . As air is drawn in on the rear side of the storm , it begins to descend as it approaches the front line of the cells . Before the reaching the leading edge , the jet dives heads to the ground as a strong downdraft , creating straight-line winds . Any mature mesoscale convective system is capable of developing its own rear-inflow jet , but questions remain as to what influences the strength of the jet . While the diabatic effects of sublimation , melting and evaporation play a role in influencing jet strength , these effects do not account for cases with strong rear-inflow jets . However , the diabatic effects are responsible for the jet subsiding behind the leading edge of the MCS . The sinking of the jet first starts when the mid level inflow goes under the trailing stratiform cloud before descending to the melting layer . There are other factors that contribute to the strength of any rear inflow jet . The strength of a rear inflow jet can be greatly increased with induced vortices at the end of the line , called `` line-end vortices '' or `` book-end vortices . '' These vortices at either end of the line will help reinforce the rear inflow towards the center of the line . The other factor that can help strengthen the jet is an environment in which the large scale flow is feeding/forcing mid-level air into the rear end of the storm .", "qid": "550", "docid": "Rear-inflow_jet", "rank": 28, "score": 94643 }, { "content": "Title: Arctic Circle (organization) Content: The Arctic Circle is a nonprofit organization introduced by President Ólafur Ragnar Grímsson of Iceland on April 15 , 2013 , at the National Press Club in Washington .

The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect .

The effort has focused on changes observed during the period of instrumental temperature record , when records are most reliable ; particularly in the last 50 years , when human activity has grown fastest and observations of the troposphere have become available . The dominant mechanisms are anthropogenic , i.e. , the result of human activity . They are : increasing atmospheric concentrations of greenhouse gases global changes to land surface , such as deforestation increasing atmospheric concentrations of aerosols . There are also natural mechanisms for variation including climate oscillations , changes in solar activity , and volcanic activity . According to the Intergovernmental Panel on Climate Change ( IPCC ) , it is `` extremely likely '' that human influence was the dominant cause of global warming between 1951 and 2010 . The IPCC defines `` extremely likely '' as indicating a probability of 95 to 100 % , based on an expert assessment of all the available evidence . Multiple lines of evidence support attribution of recent climate change to human activities : A basic physical understanding of the climate system : greenhouse gas concentrations have increased and their warming properties are well-established . Historical estimates of past climate changes suggest that the recent changes in global surface temperature are unusual . Computer-based climate models are unable to replicate the observed warming unless human greenhouse gas emissions are included . Natural forces alone ( such as solar and volcanic activity ) can not explain the observed warming .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century , with the instrumental temperature record by 2000 exceeding earlier temperatures . The term `` hockey stick graph '' was coined by the climatologist Jerry Mahlman , to describe the pattern shown by the ( MBH99 ) reconstruction , envisaging a graph that is relatively flat with a downward trend to 1900 as forming an ice hockey stick 's `` shaft '' followed by a sharp , steady increase corresponding to the `` blade '' portion . The reconstructions have featured in Intergovernmental Panel on Climate Change ( IPCC ) reports as evidence of global warming . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . Paleoclimatology dates back to the 19th century , and the concept of examining varves in lake beds and tree rings to track local climatic changes was suggested in the 1930s . In the 1960s , Hubert Lamb generalised from historical documents and temperature records of central England to propose a Medieval Warm Period from around 900 to 1300 , followed by Little Ice Age . This was the basis of a `` schematic diagram '' featured in the IPCC First Assessment Report of 1990 beside cautions that the medieval warming might not have been global . The use of indicators to get quantitative estimates of the temperature record of past centuries was developed , and by the late 1990s a number of competing teams of climatologists found indications that recent warming was exceptional . introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large scale reconstructions . Their study was featured in the IPCC Second Assessment Report of 1995 . In 1998 Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 with shading emphasising that uncertainties ( to two standard error limits ) were much greater in earlier centuries . independently produced a CPS reconstruction extending back for a thousand years , and ( MBH99 ) used the MBH98 methodology to extend their study back to 1000 . A version of the MBH99 graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , which also drew on Jones et al. 1998 and three other reconstructions to support the conclusion that , in the Northern Hemisphere , the 1990s was likely to have been the warmest decade and 1998 the warmest year during the past 1,000 years . The graph became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th century warmth was exceptional . In 2003 , as lobbying over the 1997 Kyoto Protocol intensified , a paper claiming greater medieval warmth was quickly dismissed by scientists in the Soon and Baliunas controversy . Later in 2003 , Stephen McIntyre and Ross McKitrick published disputing the data used in MBH98 paper . In 2004 Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 McIntyre and McKitrick published criticisms of the principal components analysis methodology as used in MBH98 and MBH99 . Their analysis was subsequently disputed by published papers including and which pointed to errors in the McIntyre and McKitrick methodology . Political disputes led to the formation of a panel of scientists convened by the National Research Council , their North Report in 2006 supported Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result . More than two dozen reconstructions , using various statistical methods and combinations of proxy records , support the broad consensus shown in the original 1998 hockey-stick graph , with variations in how flat the pre-20th century `` shaft '' appears . The 2007 IPCC Fourth Assessment Report cited 14 reconstructions , 10 of which covered 1,000 years or longer , to support its strengthened conclusion that it was likely that Northern Hemisphere temperatures during the 20th century were the highest in at least the past 1,300 years .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change .

Climatology now includes aspects of oceanography and biogeochemistry . Basic knowledge of climate can be used within shorter term weather forecasting using analog techniques such as the El Niño -- Southern Oscillation ( ENSO ) , the Madden -- Julian oscillation ( MJO ) , the North Atlantic oscillation ( NAO ) , the Northern Annular Mode ( NAM ) which is also known as the Arctic oscillation ( AO ) , the Northern Pacific ( NP ) Index , the Pacific decadal oscillation ( PDO ) , and the Interdecadal Pacific Oscillation ( IPO ) .

The scientific consensus is that the Earth 's climate system is unequivocally warming , and that it is extremely likely ( meaning 95 % probability or higher ) that this warming is predominantly caused by humans . It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect . This scientific opinion is expressed in synthesis reports , by scientific bodies of national or international standing , and by surveys of opinion among climate scientists . Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys . National and international science academies and scientific societies have assessed current scientific opinion on global warming . These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change . The IPCC Fourth Assessment Report stated that : Warming of the climate system is unequivocal , as evidenced by increases in global average air and ocean temperatures , the widespread melting of snow and ice , and rising global average sea level . Most of the global warming since the mid-20th century is very likely due to human activities . Benefits and costs of climate change for -LSB- human -RSB- society will vary widely by location and scale . Some of the effects in temperate and polar regions will be positive and others elsewhere will be negative . Overall , net effects are more likely to be strongly negative with larger or more rapid warming . The range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time . The resilience of many ecosystems is likely to be exceeded this century by an unprecedented combination of climate change , associated disturbances ( e.g. flooding , drought , wildfire , insects , ocean acidification ) and other global change drivers ( e.g. land-use change , pollution , fragmentation of natural systems , over-exploitation of resources ) . Some scientific bodies have recommended specific policies to governments , and science can play a role in informing an effective response to climate change . Policy decisions , however , may require value judgements and so are not included in the scientific opinion . No scientific body of national or international standing maintains a formal opinion dissenting from any of these main points . The last national or international scientific body to drop dissent was the American Association of Petroleum Geologists , which in 2007 updated its statement to its current non-committal position .

The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise . The balance of impacts of global warming become significantly negative at larger values of warming . These findings are recognized by the national science academies of all the major industrialized nations ; the consensus has strengthened over time and is now virtually unanimous .

The project was funded by the National Science Foundation as part of the International Decade of Ocean Exploration ( 1970s ) and is based in large part of the collection and analysis of a very large number of sediment cores to create a snapshot of conditions across the oceans . The CLIMAP project also resulted in maps of vegetative zones across the continents and the estimated extent of glaciation at the time . Most CLIMAP results aim to describe the Earth as it was 18 thousand years ago , but there was also an analysis to look at conditions during the previous interglacial -- 120 thousand years ago ( CLIMAP 1981 ) . CLIMAP has been a cornerstone of paleoclimate research and remains the most used sea surface temperature reconstruction of the global ocean during the last glacial maximum ( Yin and Battisti 2001 ) , but it has also been persistently controversial . CLIMAP resulted in estimates of global cooling of only 3.0 ± 0.6 ° C relative to the modern day ( Hoffert and Covey 1992 ) . The climate change during an ice age that occurs far from the continental ice sheets themselves is believed to be primarily controlled by changes in greenhouse gases , hence the conditions during the last glacial maximum provide a natural experiment for measuring the impact of changes in greenhouse gases on climate . The cited estimates of 3.0 ° C implies a climate sensitivity to carbon dioxide changes at the low end of the range proposed by the Intergovernmental Panel on Climate Change . However , CLIMAP also suggested that some of the tropics and in particular much of the Pacific Ocean were warmer than they are today . To date , no climate model has been able to reproduce the proposed warming in the Pacific ( Yin and Battisti 2001 ) , with most preferring a several degree cooling . Also , it appears that climate models which are forced to match the CLIMAP sea surface measurements are too warm to match estimates for changes at continental locations ( Pinot et al. 1999 ) . This suggests that either climate model design is missing some important unknown factor , or CLIMAP systematically overestimated the temperatures in the tropical oceans during the last glacial , though there is at present no consistent explanation for why or how this should have happened . Unfortunately cost and difficulty of collecting sediment cores from the open Pacific has limited the availability of samples that might help to confirm or disprove these observations . If the Pacific reconstruction is assumed to be in error , it would result in a larger climate sensitivity to changes in greenhouse gases .", "qid": "551", "docid": "Climate:_Long_range_Investigation,_Mapping,_and_Prediction", "rank": 62, "score": 69407 }, { "content": "Title: Thomas Stocker Content: Thomas Stocker ( born 1959 ) is a Swiss climate scientist .

Most weather phenomena occur in the lowest level of the atmosphere , the troposphere , just below the stratosphere . Weather refers to day-to-day temperature and precipitation activity , whereas climate is the term for the averaging of atmospheric conditions over longer periods of time . When used without qualification , `` weather '' is generally understood to mean the weather of Earth . Weather is driven by air pressure , temperature and moisture differences between one place and another . These differences can occur due to the sun 's angle at any particular spot , which varies with latitude . The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations : the Hadley Cell , the Ferrel Cell , the Polar Cell , and the jet stream . Weather systems in the mid-latitudes , such as extratropical cyclones , are caused by instabilities of the jet stream flow . Because the Earth 's axis is tilted relative to its orbital plane , sunlight is incident at different angles at different times of the year . On Earth 's surface , temperatures usually range ± 40 ° C ( − 40 ° F to 100 ° F ) annually . Over thousands of years , changes in Earth 's orbit can affect the amount and distribution of solar energy received by the Earth , thus influencing long-term climate and global climate change . Surface temperature differences in turn cause pressure differences . Higher altitudes are cooler than lower altitudes as most atmospheric heating is due to contact with the Earth 's surface while radiative losses to space are mostly constant . Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location . The Earth 's weather system is a chaotic system ; as a result , small changes to one part of the system can grow to have large effects on the system as a whole . Human attempts to control the weather have occurred throughout history , and there is evidence that human activities such as agriculture and industry have modified weather patterns . Studying how the weather works on other planets has been helpful in understanding how weather works on Earth . A famous landmark in the Solar System , Jupiter 's Great Red Spot , is an anticyclonic storm known to have existed for at least 300 years . However , weather is not limited to planetary bodies . A star 's corona is constantly being lost to space , creating what is essentially a very thin atmosphere throughout the Solar System .

The main forms of precipitation include drizzle , rain , sleet , snow , graupel and hail . Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor , so that the water condenses and `` precipitates '' . Thus , fog and mist are not precipitation but suspensions , because the water vapor does not condense sufficiently to precipitate . Two processes , possibly acting together , can lead to air becoming saturated : cooling the air or adding water vapor to the air . Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud . Short , intense periods of rain in scattered locations are called `` showers . '' Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain . This process is typically active when freezing rain is occurring . A stationary front is often present near the area of freezing rain and serves as the foci for forcing and rising air . Provided necessary and sufficient atmospheric moisture content , the moisture within the rising air will condense into clouds , namely stratus and cumulonimbus . Eventually , the cloud droplets will grow large enough to form raindrops and descend toward the Earth where they will freeze on contact with exposed objects . Where relatively warm water bodies are present , for example due to water evaporation from lakes , lake-effect snowfall becomes a concern downwind of the warm lakes within the cold cyclonic flow around the backside of extratropical cyclones . Lake-effect snowfall can be locally heavy . Thundersnow is possible within a cyclone 's comma head and within lake effect precipitation bands . In mountainous areas , heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation . On the leeward side of mountains , desert climates can exist due to the dry air caused by compressional heating . The movement of the monsoon trough , or intertropical convergence zone , brings rainy seasons to savannah climes . Precipitation is a major component of the water cycle , and is responsible for depositing the fresh water on the planet . Approximately 505000 km3 of water falls as precipitation each year ; 398000 km3 of it over the oceans and 107000 km3 over land . Given the Earth 's surface area , that means the globally averaged annual precipitation is 990 mm , but over land it is only 715 mm . Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes . Precipitation may occur on other celestial bodies , e.g. when it gets cold , Mars has precipitation which most likely takes the form of frost , rather than rain or snow .", "qid": "554", "docid": "Precipitation", "rank": 9, "score": 95402 }, { "content": "Title: Global storm activity of 2008 Content: Global storm activity of 2008 profiles the major worldwide storms , including blizzards , ice storms , and other winter events , from January 1 , 2008 to December 31 , 2008 .

Knowledge of tropical cyclone rainfall climatology is helpful in the determination of a tropical cyclone rainfall forecast . More rainfall falls in advance of the center of the cyclone than in its wake . The heaviest rainfall falls within its central dense overcast and eyewall . Slow moving tropical cyclones , like Hurricane Danny and Hurricane Wilma , can lead to the highest rainfall amounts due to prolonged heavy rains over a specific location . However , vertical wind shear leads to decreased rainfall amounts , as rainfall is favored downshear and slightly left of the center and the upshear side is left devoid of rainfall . The presence of hills or mountains near the coast , as is the case across much of Mexico , Haiti , the Dominican Republic , much of Central America , Madagascar , Réunion , China , and Japan act to magnify amounts on their windward side due to forced ascent causing heavy rainfall in the mountains . A strong system moving through the mid latitudes , such as a cold front , can lead to high amounts from tropical systems , occurring well in advance of its center . Movement of a tropical cyclone over cool water will also limit its rainfall potential . A combination of factors can lead to exceptionally high rainfall amounts , as was seen during Hurricane Mitch in Central America . Use of forecast models can help determine the magnitude and pattern of the rainfall expected . Climatology and persistence models , such as r-CLIPER , can create a baseline for tropical cyclone rainfall forecast skill . Simplified forecast models , such as the Kraft technique and the eight and sixteen-inch rules , can create quick and simple rainfall forecasts , but come with a variety of assumptions which may not be true , such as assuming average forward motion , average storm size , and a knowledge of the rainfall observing network the tropical cyclone is moving towards .

In 2013 , the CSIRO released a report stating that Australia is becoming hotter , and that it will experience more extreme heat and longer fire seasons because of climate change . In 2014 , the Bureau of Meteorology released a report on the state of Australia 's climate that highlighted several key points , including the significant increase in Australia 's temperatures ( particularly night-time temperatures ) and the increasing frequency of bush fires , droughts and floods , which have all been linked to climate change . Since the beginning of the 20th century Australia has experienced an increase of nearly 1 ° C in average annual temperatures , with warming occurring at twice the rate over the past 50 years than in the previous 50 years . Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the impacts of climate change in Australia . Rainfall in southwestern Australia has decreased by 10 -- 20 % since the 1970s , while southeastern Australia has also experienced a moderate decline since the 1990s . Rainfall patterns are expected to be problematic , as rain has become heavier and infrequent , as well as more common in summer rather than in winter , with little or no uptrend in rainfall in the Western Plateau and the Central Lowlands of Australia . Water sources in the southeastern areas of Australia have depleted due to increasing population in urban areas ( rising demand ) coupled with climate change factors such as persistent prolonged drought ( diminishing supply ) . At the same time , Australia continues to have the highest per capita greenhouse gas emissions . Temperatures in Australia have also risen dramatically since 1910 and nights have become warmer . A carbon tax was introduced in 2011 by the Gillard government in an effort to reduce the impact of climate change and despite some criticism , it successfully reduced Australia 's carbon dioxide emissions , with coal generation down 11 % since 2008 -- 09 . The subsequent Australian Government , elected in 2013 under then Prime Minister Tony Abbott was criticised for being `` in complete denial about climate change '' . Furthermore , the Abbott government repealed the carbon tax on 17 July 2014 in a heavily criticised move . The renewable energy target ( RET ) , launched in 2001 , was heavily modified under Abbott 's government . However , under the government of Malcolm Turnbull , Australia attended the 2015 United Nations Climate Change Conference and adopted the Paris Agreement . This agreement includes a review of emission reduction targets every 5 years from 2020 . The federal government and all state governments ( New South Wales , Victoria , Queensland , South Australia , Western Australia , Tasmania , Northern Territory and the Australian Capital Territory ) have explicitly recognised that climate change is being caused by greenhouse gas emissions , in conformity with the scientific opinion on climate change . Sectors of the population have campaigned against new coal mines and coal-fired power stations , reflecting concerns about the effects of global warming on Australia . The Garnaut Climate Change Review predicted that a net benefit to Australia may be derived by stabilising greenhouse gases in the atmosphere at 450ppm CO2 eq .

Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth . It provides suitable conditions for many types of ecosystems , as well as water for hydroelectric power plants and crop irrigation . The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts . If enough moisture and upward motion is present , precipitation falls from convective clouds ( those with strong upward vertical motion ) such as cumulonimbus ( thunder clouds ) which can organize into narrow rainbands . In mountainous areas , heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains . On the leeward side of mountains , desert climates can exist due to the dry air caused by downslope flow which causes heating and drying of the air mass . The movement of the monsoon trough , or intertropical convergence zone , brings rainy seasons to savannah climes . The urban heat island effect leads to increased rainfall , both in amounts and intensity , downwind of cities .

Formally , a wider study includes water falling as ice crystals , i.e. hail , sleet , snow ( parts of the hydrological cycle known as precipitation ) . The aim of rainfall climatology is to measure , understand and predict rain distribution across different regions of planet Earth , a factor of air pressure , humidity , topography , cloud type and raindrop size , via direct measurement and remote sensing data acquisition . Current technologies accurately predict rainfall 3 -- 4 days in advance using numerical weather prediction . Geostationary orbiting satellites gather IR and visual wavelength data to measure realtime localised rainfall by estimating cloud albedo , water content , and the corresponding probability of rain . Geographic distribution of rain is largely governed by climate type , topography and habitat humidity . In mountainous areas , heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation . On the leeward side of mountains , desert climates can exist due to the dry air caused by compressional heating . The movement of the monsoon trough , or intertropical convergence zone , brings rainy seasons to savannah climes . The urban heat island effect leads to increased rainfall , both in amounts and intensity , downwind of cities .

Precipitation is a major component of the water cycle , and is responsible for depositing most of the fresh water on the planet . Approximately 505000 km3 of water falls as precipitation each year ; 398000 km3 of it over the oceans .

Australia 's rainfall is mainly regulated by the movement of the monsoon trough during the summer rainy season , with lesser amounts falling during the winter and spring in its southernmost sections . Almost whole North Africa is semi-arid , arid or hyper-arid , containing the Sahara Desert which is the largest hot desert in the world , while central Africa ( known as Sub-Saharan Africa ) sees an annual rainy season regulated by the movement of the intertropical convergence zone or monsoon trough , though the Sahel Belt located at the south of the Sahara Desert knows an extremely intense and a nearly permanent dry season and only receives minimum summer rainfall . Across Asia , a large annual rainfall minimum , composed primarily of deserts , stretches from the Gobi Desert in Mongolia west-southwest through Pakistan and Iran into the Arabian Desert in Saudi Arabia . In Asia , rainfall is favored across its southern portion from India east and northeast across the Philippines and southern China into Japan due to the monsoon advecting moisture primarily from the Indian Ocean into the region . Similar , but weaker , monsoon circulations are present over North America and Australia . In Europe , the wettest regions are in the Alps and downwind of bodies of water , particularly the Atlantic west coasts . Within North America , the drier areas of the United States are the Desert Southwest , Great Basin , valleys of northeast Arizona , eastern Utah , central Wyoming , and the Columbia Basin . Other dry regions within the continent are far northern Canada and the Sonoran Desert of northwest Mexico . The Pacific Northwest United States , the Rockies of British Columbia , and the coastal ranges of Alaska are the wettest locations in North America . The equatorial region near the Intertropical Convergence Zone ( ITCZ ) , or monsoon trough , is the wettest portion of the world 's continents . Annually , the rain belt within the tropics marches northward by August , then moves back southward into the Southern Hemisphere by February and March .", "qid": "554", "docid": "Earth_rainfall_climatology", "rank": 57, "score": 81249 }, { "content": "Title: Interception (water) Content: Interception refers to precipitation that does not reach the soil , but is instead intercepted by the leaves , branches of plants and the forest floor . It occurs in the canopy ( i.e. canopy interception ) , and in the forest floor or litter layer ( i.e. forest floor interception ) . Because of evaporation , interception of liquid water generally leads to loss of that precipitation for the drainage basin , except for cases such as fog interception , but increase flood protection dramatically , Alila et al. , ( 2009 ) . Intercepted snowfall does not result in any notable amount of evaporation , and most of the snow falls off the tree by wind or melts . However , intercepted snow can more easily drift with the wind , out of the watershed . Conifers have a greater interception capacity than hardwoods . Their needles gives them more surface area for droplets to adhere to , and they have foliage in spring and fall , therefore interception also depends on the type of vegetation in a wooded area . Mitscherlich in 1971 calculated the water storage potential as interception values for different species and stand densities . A storm event might produce 50 - 100 mm of rainfall and 4 mm might be the maximum intercepted in this way . Grah and Wilson in 1944 did sprinkling experiments where they watered plants to see how much of the intercepted is kept after watering stops . The interception depends on the leaf area index and what kind of leaves they are .

The small convergence zone forms within specific weather conditions sometimes found in the wake of extratropical cyclones shifting east of the area . Given air pressure decreasing with both longitude and latitude , as well as weak synoptic low-level flow , winds are channeled east along the Mohawk Valley and south through the Hudson Valley , converging over Albany . With sufficient moisture in the lower atmosphere , a localized area of precipitation may form where the valleys meet , extending for several miles around Albany . The process manifests primarily in the lowest 2500 ft of the atmosphere . MHC-induced precipitation occurs predominately in the winter . It typically produces low clouds and light snowfall , often locally prolonging significant snow events by several hours . The strongest MHC events may yield snowfall rates approaching 1 in ( 2.5 cm ) per hour . Occasionally , MHC contributes to shower and thunderstorm formation in the warm season .

This process is known as the Bergeron Process , and is believed to be the primary process by which precipitation is formed . Bergeron was one of the principal scientists in the Bergen School of Meteorology , which transformed this science by introducing a new conceptual foundation for understanding and predicting weather . While developing innovative methods of forecasting , the Bergen scientists established the notion of weather fronts and elaborated a new model of extratropical cyclones that accounted for their birth , growth , and decay .

Alaska Peninsula brown bears are a very large brown bear subspecies , usually ranging in weight from 800 to 1,200 pounds ( 363 to 544 kg ) . They are found in high densities along the southern Alaskan coast due not only to the large amount of clams and sedge grass but also to the annual salmon runs ; this allows them to attain huge sizes , some of the biggest in the world . They may gather in large numbers at feeding sites , such as Brooks Falls and McNeil Falls , both in Katmai National Park near King Salmon . There is debate as to if Alaska Peninsula brown bears should be referred to as `` grizzlies '' along with all other North American subspecies of the brown bear . There is confusion experienced when referring to inland and coastal ones separately , but biologists still maintain that coastal ones are truly brown bears . However , it is considered correct to place all North American members of U. arctos in the subspecies horribilis except the giant Kodiak bears of Kodiak Island . To avoid confusion , many simply refer to all North American members , including Kodiaks , as `` grizzly bears . '' Prized by hunters for their skulls and hides , up to 500 of Alaska 's 1,500 brown bears killed yearly by hunters come from the Alaska Peninsula .

Physiologically , the Kodiak bear is very similar to the other brown bear subspecies , such as the mainland grizzly bear ( Ursus arctos horribilis ) and the now-extinct California grizzly bear ( U. a. californicus † ) , with the main difference being in size . While there is generally much variation in size between brown bears in different areas , most usually weigh between 115 and 360 kg ( 254 and 794 lb ) . The Kodiak bear , on the other hand , commonly reaches sizes of 300 to , and has even been known to exceed weights of 680 kg on occasion . Despite this large variation in size , the diet and lifestyle of the Kodiak bear does not differ greatly from that of other brown bears . Ever since the first humans arrived in Alaska over the Bering land bridge , encounters between people and Kodiak bears have occurred . Today , these encounters have become relatively more common as a result of the increase in the human population in the region . Such encounters have included the hunting of bears by humans for their fur or meat , and , less commonly , attacks by bears upon humans .

Although most polar bears are born on land , they spend most of their time on the sea ice . Their scientific name means `` maritime bear '' and derives from this fact . Polar bears hunt their preferred food of seals from the edge of sea ice , often living off fat reserves when no sea ice is present . Because of their dependence on the sea ice , polar bears are classified as marine mammals ; an alternative basis for classification as marine mammals is that they depend on the ocean as their main food source . Because of expected habitat loss caused by climate change , the polar bear is classified as a vulnerable species , and at least three of the nineteen polar bear subpopulations are currently in decline . For decades , large-scale hunting raised international concern for the future of the species , but populations rebounded after controls and quotas began to take effect .

JJ1 , also known as Bruno in the German press ( some newspapers also gave the bear different names , such as Beppo or Petzi ) , is believed to have been the first brown bear on German soil in 170 years . Previously , the last sighting of a bear in what is now Germany was recorded in 1838 when hunters shot a bear in Bavaria . Initially heralded as a welcome visitor and a symbol of the success of endangered species reintroduction programs , his dietary preferences for sheep , chickens , and beehives led government officials to believe that he could become a threat to humans , and they ordered that he be shot or captured . Public objection to the destruction order resulted in its revision , and the German government tried to use non-lethal means to sedate and capture the bear . JJ1 was described as bloodthirsty , clever , and fast . Bavarian minister-president Edmund Stoiber referred to him as a Problembär ( `` problem bear '' ) . Farmers claimed the bear `` enjoyed killing , '' because he typically killed sheep without eating them . This behavior , called surplus killing , common among predators , was construed as being caused by interaction with people . As of 21 June 2006 , his kills included 33 sheep , four domestic rabbits , one guinea pig , as well as some hens and goats . Further concern was expressed due to the proximity of the bear 's preferred prey to humans . Purportedly , several attempts were made to catch Bruno alive , assisted by a team of Finnish bear hunters using five dogs ( which were described in the press as either Karelian Bear Dogs or Elkhounds ) . The attempts failed , and JJ1 was shot at Rotwand mountain ( see Miesbach ( district ) ) near Lake Spitzingsee in southern Bavaria in the early morning of 26 June . The magazine Private Eye reported in early July 2006 that Bruno was part of an EU-funded $ 1 million conservation project in Italy . A spokesman said that there had been `` co-ordination '' between Italy , Austria and Slovenia to ensure the bear 's welfare but apparently Germany had not been informed . The Life Ursus reintroduction project of the Italian province of Trento had introduced 10 Slovenian bears in the region monitoring them . JJ1 was the first son of Jurka and Joze ( thus the name JJ1 ) , JJ3 the younger brother also showed an aggressive character and wandered in Switzerland in 2008 and was killed there . Because of this second problem the mother Jurka was put in captivity in Italy among protests of the environmentalists , authorities of the park maintained that 50 % of the incidents involving bears had been caused by Jurka or her descendant . Bruno has become a subject of diplomatic strife . The Italian government in Rome has declared Bruno state property of Italy , and is demanding his return .

While the polar bear is mostly carnivorous , and the giant panda feeds almost entirely on bamboo , the remaining six species are omnivorous with varied diets . With the exception of courting individuals and mothers with their young , bears are typically solitary animals . They may be diurnal or nocturnal and have an excellent sense of smell . Despite their heavy build and awkward gait , they are adept runners , climbers , and swimmers . Bears use shelters , such as caves and logs , as their dens ; most species occupy their dens during the winter for a long period of hibernation , up to 100 days . Bears have been hunted since prehistoric times for their meat and fur ; they have been used for bear-baiting and other forms of entertainment , such as being made to dance . With their powerful physical presence , they play a prominent role in the arts , mythology , and other cultural aspects of various human societies . In modern times , bears have come under pressure through encroachment on their habitats and illegal trade in bear parts , including the Asian bile bear market .

Once this warm surge inundated the area , a remarkably prolonged period of record setting temperatures ensued . NOAA 's National Climate Data Center reported that over 7,000 daily record high temperatures were tied or broken from 1 March through 27 March .

The week of March 18 also set record temperatures in Manitoba and much of Ontario as well as into the Maritime Provinces . Non-severe thunderstorms were reported on the evening hours of March 21 , through to the early morning hours March 22 into northern Ontario . In addition , NCEP/NCAR Reanalysis data show that the atmospheric pattern was so persistent that much of the Midwest and Northeast , and up into Ontario , had temperature departures over periods of several days to a week or more of magnitudes which would be unusual even for a single day . Averaged over the seven-day period from March 16 to March 22 inclusive , nearly the entire area of the Midwest and Northeast U.S. and most of Ontario and Quebec had temperatures 10 ° C ( 18 ° F ) or more above the 1981-2010 average . Even more dramatically , most of Iowa and Minnesota , all of Wisconsin and Michigan , and most of southeastern Ontario had seven-day mean temperatures more than 15 ° C ( 27 ° F ) above the climatological average for the same period . An 84 ° F high at Madison , WI in early March was 43 ° F above average and followed an overnight low of 60 ° F , 35 degrees above normal the daily high being more than seven standard deviations above the mean . The absolute temperature and departure statistically would be equivalent to a mid-July high at that station in excess of 125 ° F or more ; the highest temperature recorded there was 107 ° at least once during the heat waves of the middle 1930s .

Thermodynamic temperature is defined by the third law of thermodynamics in which the theoretically lowest temperature is the null or zero point . At this point , absolute zero , the particle constituents of matter have minimal motion and can become no colder . In the quantum-mechanical description , matter at absolute zero is in its ground state , which is its state of lowest energy . Thermodynamic temperature is often also called absolute temperature , for two reasons : one , proposed by Kelvin , that it does not depend on the properties of a particular material ; two that it refers to an absolute zero according to the properties of the ideal gas . The International System of Units specifies a particular scale for thermodynamic temperature . It uses the kelvin scale for measurement and selects the triple point of water at 273.16 K as the fundamental fixing point . Other scales have been in use historically . The Rankine scale , using the degree Fahrenheit as its unit interval , is still in use as part of the English Engineering Units in the United States in some engineering fields . ITS-90 gives a practical means of estimating the thermodynamic temperature to a very high degree of accuracy . Roughly , the temperature of a body at rest is a measure of the mean of the energy of the translational , vibrational and rotational motions of matter 's particle constituents , such as molecules , atoms , and subatomic particles . The full variety of these kinetic motions , along with potential energies of particles , and also occasionally certain other types of particle energy in equilibrium with these , make up the total internal energy of a substance . Internal energy is loosely called the heat energy or thermal energy in conditions when no work is done upon the substance by its surroundings , or by the substance upon the surroundings . Internal energy may be stored in a number of ways within a substance , each way constituting a `` degree of freedom '' . At equilibrium , each degree of freedom will have on average the same energy : where is the Boltzmann constant , unless that degree of freedom is in the quantum regime . The internal degrees of freedom ( rotation , vibration , etc. ) may be in the quantum regime at room temperature , but the translational degrees of freedom will be in the classical regime except at extremely low temperatures ( fractions of kelvins ) and it may be said that , for most situations , the thermodynamic temperature is specified by the average translational kinetic energy of the particles .", "qid": "556", "docid": "Thermodynamic_temperature", "rank": 48, "score": 89395 }, { "content": "Title: Climate of East Anglia Content: The climate of East Anglia is generally dry and mild .

Due to the lack of solar heating and very strong radiative cooling from carbon dioxide , the mesosphere is the coldest region on Earth with temperatures as low as -100 ° C ( -148 ° F or 173 K ) . The altitude of the mesopause for many years was assumed to be at around 85 km ( 53 mi . ) , but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km . ( 62 mi . ) Another feature is that the summer mesopause is cooler than the winter ( sometimes referred to as the mesopause anomaly ) . It is due to a summer-to-winter circulation giving rise to upwelling at the summer pole and downwelling at the winter pole . Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause . In the mesosphere the summer-to-winter circulation is due to gravity wave dissipation , which deposits momentum against the mean east-west flow , resulting in a small north-south circulation . In recent years the mesopause has also been the focus of studies on global climate change associated with increases in CO2 . Unlike the troposphere , where greenhouse gases result in the atmosphere heating up , increased CO2 in the mesosphere acts to cool the atmosphere due to increased radiative emission . This results in a measurable effect - the mesopause should become cooler with increased CO2 .

The weather in the tropics is dominated by the tropical rain belt , which moves from the northern to the southern tropics and back over the course of the year . The tropical rain belt lies in the southern hemisphere roughly from October to March ; during that time the northern tropics have a dry season with sparser precipitation , and days are typically sunny throughout . From April to September , the rain belt lies in the northern hemisphere , and the southern tropics have their dry season . Under the Köppen climate classification , for tropical climates , a dry season month is defined as a month when average precipitation is below 60 mm . The dry season has low humidity , and some watering holes and rivers dry up . This lack of water ( and hence of food ) may force many grazing animals to migrate to more fertile spots . Examples of such animals are zebras , elephants , and wildebeest . Because of the lack of water in the plants , bushfires are common . Data shows that in Africa the start of the dry season coincides with a rise in the cases of measles -- which researchers believe might be attributed to the higher concentration of people in the dry season , as agricultural operations are all but impossible without irrigation . During this time , some farmers move into cities , creating hubs of higher population density , and allowing disease to spread more easily . The rain belt reaches roughly as far north as the Tropic of Cancer and as far south as the Tropic of Capricorn . Near these latitudes , there is one wet season and one dry season annually . At the equator there are two wet and two dry seasons , as the rain belt passes over twice a year , once moving north and once moving south . Between the tropics and the equator , locations may experience a short wet and a long wet season ; and a short dry and a long dry season . Local geography may substantially modify these climate patterns , however . New data shows that in the seasonal parts of the South American Amazon forest , foliage growth and coverage varies between the dry and wet seasons -- with about 25 % more leaves and faster growth in the dry season . Researchers believe that the Amazon itself has an effect in bringing the onset of the wet season : by growing more foliage , it evaporates more water . However , this growth appears only in the undisturbed parts of the Amazon basin , where researchers believe roots can reach deeper and gather more rain water .

The annual rainfall averages about seven inches , falling mainly during July and August . The southwesterly monsoon wind begins to blow in mid-February and continues until the end of September , whereas the cool northerly wind blows during the winter months from October to January . Sindh lies between the two monsoons -- the southwest monsoon from the Indian Ocean and the northeast or retreating monsoon , deflected towards it by the Himalayan mountains -- and escapes the influence of both . The average rainfall in Sindh is only 6 - per year . The region 's scarcity of rainfall is compensated by the inundation of the Indus twice a year , caused by the spring and summer melting of Himalayan snow and by rainfall in the monsoon season . These natural patterns have recently changed somewhat with the construction of dams and barrages on the Indus River . Parts of southeastern Sindh receive rainfall of up to 36 in and some cities have received very heavy rainfall on occasion . In 2005 , Hyderabad received 14.4 in in just 11 hours .

The nation has four seasons : winter ( December , January and February ) , summer ( March , April and May ) , a monsoon rainy season ( June to September ) , and a post-monsoon period ( October to November ) . India 's geography and geology are climatically pivotal : the Thar Desert in the northwest and the Himalayas in the north work in tandem to effect a culturally and economically important monsoonal regime . As Earth 's highest and most massive mountain range , the Himalayas bar the influx of frigid katabatic winds from the icy Tibetan Plateau and northerly Central Asia . Most of North India is thus kept warm or is only mildly chilly or cold during winter ; the same thermal dam keeps most regions in India hot in summer . Though the Tropic of Cancer -- the boundary between the tropics and subtropics -- passes through the middle of India , the bulk of the country can be regarded as climatically tropical . As in much of the tropics , monsoonal and other weather patterns in India can be wildly unstable : epochal droughts , floods , cyclones , and other natural disasters are sporadic , but have displaced or ended millions of human lives .

The story focuses on the boy and his father who calls him Schatz ( German , meaning darling ) . When the boy gets the flu , a doctor is called in and recommends three different medicines and tells the boy 's father that his temperature is 102 degrees Fahrenheit ( 39 degrees Celsius ) . He is very quiet and depressed , finally asking when he will die ; he had thought that a 102 degree temperature was lethal because he heard in France ( where Celsius is used ) that one can not live with a temperature over 44 degrees . When the father explains to him the difference in scales , the boy slowly relaxes , and the next day , `` he cried very easily at little things that were of no importance . '' The story ´ s theme is the boy 's misunderstanding leading to the fear of his death without his father realizing this . analysis : a ) A fateful misunderstanding The misunderstanding between father and son exists because they do not have the same thoughts . The boy thinks he will die but the father thinks his son is only ill . The boy uses the word `` it '' to describe the process of dying . The father also uses the word `` it '' , but to describe that it is no problem for him to stay at home with his son . Since they only use the pronoun `` it '' neither of them knows what the other person is talking about . b ) The hunting scene The landscape is described as frozen because it 's a cold day . The father 's behaviour is also cold because he is shooting birds and killing them . The father 's inability to understand his son is symbolically expressed by the layer of ice separating him from nature ( he is helpless on the icy surface ) ; the same helplessness applies to his relationship to his son . c ) Interdependence between theme and point of view The theme focuses on the misunderstanding between father and son , which is disastrous for the son due to the lack of knowledge as far as the different scales are concerned . The failure in communication leads to the son ´ s being afraid of dying . This is why Hemingway chooses the first person narrator with a limited point of view . He is therefore confined to presenting mere observations and suppositions . `` The boy was evidently holding tight onto himself about something '' , which is only one example of the father ´ s suppositions . The father is only an observer of the scene without realizing the son ´ s fears . He remains detached and can not imagine and feel the son ´ s distress . An observer narrator is the best way of expressing this distance between the two . Hemingway cleverly chooses this point of view as one means of showing the lack of mutual closeness in the relationship between father and son .

Species that have a lot of plasticity tend to be generalists.
[ { "content": "Title: Generalist and specialist species Content: A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources ( for example , a heterotroph with a varied diet ) . A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet . Most organisms do not all fit neatly into either group , however . Some species are highly specialized ( the most extreme case being monophagy ) , others less so , and some can tolerate many different environments . In other words , there is a continuum from highly-specialized to broadly-generalist species . Omnivores are usually generalists . Herbivores are often specialists , but those that eat a variety of plants may be considered generalists . A well-known example of a specialist animal is the koala , which subsists almost entirely on eucalyptus leaves . The raccoon is a generalist because it has a natural range that includes most of North and Central America , and it is omnivorous , eating berries , insects , eggs and small animals . Monophagous organisms feed exclusively , or nearly so , on a single other species . The distinction between generalists and specialists is not limited to animals . For example , some plants require a narrow range of temperatures , soil conditions and precipitation to survive while others can tolerate a broader range of conditions . A cactus could be considered a specialist species . It will die during winters at high latitudes or if it receives too much water . When body weight is controlled for , specialist feeders such as insectivores and frugivores have larger home ranges than generalists like some folivores ( leaf eaters ) . Because their food source is less abundant , they need a bigger area for foraging . An example comes from the research of Tim Clutton-Brock , who found that the black and white colobus , a folivore generalist , needs a home range of only 15ha . On the other hand , the more specialized red colobus monkey has a home range of 70 ha , which it requires to find patchy shoots , flowers and fruit . When environmental conditions change , generalists are able to adapt , but specialists tend to fall victim to extinction much more easily . For example , if a species of fish were to go extinct , any specialist parasites would also face extinction . On the other hand , a species with a highly specialized ecological niche is more effective at competing with other organisms . For example , a fish and its parasites are in an evolutionary arms race , a form of co-evolution , in which the fish constantly develops defenses against the parasite , while the parasite in turn evolves adaptations to cope with the specific defenses of its host . This tends to drive the speciation of more specialized species provided conditions remain relatively stable . This involves niche partitioning as new species are formed , and biodiversity is increased .", "qid": "558", "docid": "Generalist_and_specialist_species", "rank": 1, "score": 103763 }, { "content": "Title: Plasticity (physics) Content: In physics and materials science , plasticity describes the deformation of a ( solid ) material undergoing non-reversible changes of shape in response to applied forces . For example , a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself . In engineering , the transition from elastic behavior to plastic behavior is called yield . Plastic deformation is observed in most materials , particularly metals , soils , rocks , concrete , foams , bone and skin . However , the physical mechanisms that cause plastic deformation can vary widely . At a crystalline scale , plasticity in metals is usually a consequence of dislocations . Such defects are relatively rare in most crystalline materials , but are numerous in some and part of their crystal structure ; in such cases , plastic crystallinity can result . In brittle materials such as rock , concrete and bone , plasticity is caused predominantly by slip at microcracks . For many ductile metals , tensile loading applied to a sample will cause it to behave in an elastic manner . Each increment of load is accompanied by a proportional increment in extension . When the load is removed , the piece returns to its original size . However , once the load exceeds a threshold -- the yield strength -- the extension increases more rapidly than in the elastic region ; now when the load is removed , some degree of extension will remain . Elastic deformation , however , is an approximation and its quality depends on the time frame considered and loading speed . If , as indicated in the graph opposite , the deformation includes elastic deformation , it is also often referred to as `` elasto-plastic deformation '' or `` elastic-plastic deformation '' . Perfect plasticity is a property of materials to undergo irreversible deformation without any increase in stresses or loads . Plastic materials with hardening necessitate increasingly higher stresses to result in further plastic deformation . Generally , plastic deformation is also dependent on the deformation speed , i.e. higher stresses usually have to be applied to increase the rate of deformation . Such materials are said to deform visco-plastically .", "qid": "558", "docid": "Plasticity_(physics)", "rank": 2, "score": 93450 }, { "content": "Title: Rock mass plasticity Content: thumb | 300px | right | Boudinaged quartz vein ( with strain fringe ) showing sinistral shear sense , Starlight Pit , Fortnum Gold Mine , Western Australia Plasticity theory for rocks is concerned with the response of rocks to loads beyond the elastic limit . Historically , conventional wisdom has it that rock is brittle and fails by fracture while plasticity is identified with ductile materials . In field scale rock masses , structural discontinuities exist in the rock indicating that failure has taken place . Since the rock has not fallen apart , contrary to expectation of brittle behavior , clearly elasticity theory is not the last work . Theoretically , the concept of rock plasticity is based on soil plasticity which is different from metal plasticity . In metal plasticity , for example in steel , the size of a dislocation is sub-grain size while for soil it is the relative movement of microscopic grains . The theory of soil plasticity was developed in the 1960s at Rice University to provide for inelastic effects not observed in metals . Typical behaviors observed in rocks include strain softening , perfect plasticity , and work hardening . Application of continuum theory is possible in jointed rocks because of the continuity of tractions across joints even through displacements may be discontinuous .

In developed countries , about a third of plastic is used in packaging and another third in buildings such as piping used in plumbing or vinyl siding . Other uses include automobiles ( up to 20 % plastic ) , furniture , and toys . In the developing world , the ratios may be different - for example , reportedly 42 % of India 's consumption is used in packaging . Plastics have many uses in the medical field as well , to include polymer implants , however the field of plastic surgery is not named for use of plastic material , but rather the more generic meaning of the word plasticity in regard to the reshaping of flesh . The world 's first fully synthetic plastic was bakelite , invented in New York in 1907 by Leo Baekeland who coined the term ` plastics ' . Many chemists contributed to the materials science of plastics , including Nobel laureate Hermann Staudinger who has been called `` the father of polymer chemistry '' and Herman Mark , known as `` the father of polymer physics '' . The success and dominance of plastics starting in the early 20th century led to environmental concerns regarding its slow decomposition rate after being discarded as trash due to its composition of very large molecules . Toward the end of the century , one approach to this problem was met with wide efforts toward recycling .", "qid": "558", "docid": "Plastic", "rank": 24, "score": 79547 }, { "content": "Title: Plastic arts Content: Plastic arts are art forms which involve physical manipulation of a plastic medium by moulding or modeling such as sculpture or ceramics .

A plastic is a polymeric material that is in a semi-liquid state , having the property of plasticity and exhibiting flow . Plastics engineering encompasses plastics material and plastic machinery . Plastic Machinery is the general term for all types of machinery and devices used in the plastics processing industry . The nature of plastic materials poses unique challenges to an engineer . Mechanical properties of plastics are often difficult to quantify , and the plastics engineer has to design a product that meets certain specifications while keeping costs to a minimum . Other properties that the plastics engineer has to address include : outdoor weatherability , thermal properties such as upper use temperature , electrical properties , barrier properties , and resistance to chemical attack . In plastics engineering , as in most engineering disciplines , the economics of a product plays an important role . The cost of plastic materials ranges from the cheapest commodity plastics used in mass-produced consumer products to the very expensive , specialty plastics . The cost of a plastic product is measured in different ways , and the absolute cost of a plastic material is difficult to ascertain . Cost is often measured in price per pound of material , or price per unit volume of material . In many cases however , it is important for a product to meet certain specifications , and cost could then be measured in price per unit of a property . Price with respect to processibility is often important , as some materials need to be processed at very high temperatures , increasing the amount of cooling time a part needs . In a large production run cooling time is very expensive . Some plastics are manufactured from re-cycled materials but their use in engineering tends to be limited because the consistency of formulation and their physical properties tend to be less consistent . Electrical and electronic equipment and motor vehicle markets together accounted for 58 percent of engineered plastics demand in 2003 . Engineered plastics demand in the US was estimated at $ 9,702 million in 2007 . A big challenge for plastics engineers is the reduction of the ecological footprints of their products . First attempts like the Vinyloop process can guarantee that a product 's primary energy demand is 46 percent lower than conventional produced PVC . The global warming potential is 39 percent lower .", "qid": "558", "docid": "Plastics_engineering", "rank": 26, "score": 78110 }, { "content": "Title: Nonsynaptic plasticity Content: Nonsynaptic plasticity is a form of neuroplasticity that involves modification of ion channel function in the axon , dendrites , and cell body that results in specific changes in the integration of excitatory postsynaptic potentials ( EPSPs ) and inhibitory postsynaptic potentials ( IPSPs ) .

It is this trait to retain and form memories that is associated with neural plasticity and therefore many of the functions individuals perform on a daily basis . This plasticity occurs as a result of changes in gene expression which are triggered by signaling cascades that are activated by various signaling molecules ( e.g. , calcium , dopamine , and glutamate , among many others ) during increased neuronal activity .

These mechanisms depend on current synaptic `` state '' , as set by ongoing extrinsic influences such as the level of synaptic inhibition , the activity of modulatory afferents such as catecholamines , and the pool of hormones affecting the synapses under study . Recently , it has become clear that the prior history of synaptic activity is an additional variable that influences the synaptic state , and thereby the degree , of LTP or LTD produced by a given experimental protocol . In a sense , then , synaptic plasticity is governed by an activity-dependent plasticity of the synaptic state ; such plasticity of synaptic plasticity has been termed metaplasticity .

Experiments have been done to test inescapability and insolubility . Fergus Lowe has questioned the generality of schedule effects in cases of fixed-interval performance among humans and non-humans . The ability to generalize information from one situation to another is a function of several factors . The reliability of the original information ; the paradigm 's validity ; your understanding of the paradigm and the true determinants of the behavior and the relevant details of the situations in question ; and the similarity between the original source of the data and the situation to which it is to be applied .

On the other hand , as plastic is broken down into smaller pieces and eventually microplastics , there is a higher likelihood that it will be consumed by plankton and enter into the food chain . As plankton are eaten by larger organisms , the plastic may eventually accumulate in fish eaten by humans .

Rate-dependence in this context means that the deformation of the material depends on the rate at which loads are applied . The inelastic behavior that is the subject of viscoplasticity is plastic deformation which means that the material undergoes unrecoverable deformations when a load level is reached . Rate-dependent plasticity is important for transient plasticity calculations . The main difference between rate-independent plastic and viscoplastic material models is that the latter exhibit not only permanent deformations after the application of loads but continue to undergo a creep flow as a function of time under the influence of the applied load . The elastic response of viscoplastic materials can be represented in one-dimension by Hookean spring elements . Rate-dependence can be represented by nonlinear dashpot elements in a manner similar to viscoelasticity . Plasticity can be accounted for by adding sliding frictional elements as shown in Figure 1 . In the figure E is the modulus of elasticity , λ is the viscosity parameter and N is a power-law type parameter that represents non-linear dashpot -LSB- σ ( dε / dt ) = σ = λ ( dε / dt ) ( 1/N ) -RSB- . The sliding element can have a yield stress ( σy ) that is strain rate dependent , or even constant , as shown in Figure 1c . Viscoplasticity is usually modeled in three-dimensions using overstress models of the Perzyna or Duvaut-Lions types . In these models , the stress is allowed to increase beyond the rate-independent yield surface upon application of a load and then allowed to relax back to the yield surface over time . The yield surface is usually assumed not to be rate-dependent in such models . An alternative approach is to add a strain rate dependence to the yield stress and use the techniques of rate independent plasticity to calculate the response of a material For metals and alloys , viscoplasticity is the macroscopic behavior caused by a mechanism linked to the movement of dislocations in grains , with superposed effects of inter-crystalline gliding . The mechanism usually becomes dominant at temperatures greater than approximately one third of the absolute melting temperature . However , certain alloys exhibit viscoplasticity at room temperature ( 300K ) . For polymers , wood , and bitumen , the theory of viscoplasticity is required to describe behavior beyond the limit of elasticity or viscoelasticity . In general , viscoplasticity theories are useful in areas such as the calculation of permanent deformations , the prediction of the plastic collapse of structures , the investigation of stability , crash simulations , systems exposed to high temperatures such as turbines in engines , e.g. a power plant , dynamic problems and systems exposed to high strain rates .", "qid": "558", "docid": "Viscoplasticity", "rank": 54, "score": 72093 }, { "content": "Title: Plasticizer Content: Plasticizers ( UK : plasticisers ) or dispersants are additives that increase the plasticity or viscosity of a material .

However , the mechanisms that regulate this process were not understood until Klann 's laboratory published a number of seminal studies describing the translational control mechanisms that are required for proper long-lasting synaptic plasticity and long-term memory . In addition , Klann 's laboratory subsequently demonstrated that dysregulated translational control mechanisms are involved in several brain disorders , including fragile X syndromeand autism . His laboratory uses a number of experimental approaches to dissect the molecular mechanisms necessary for maintaining long-lasting changes in synaptic strength and memory . Detailed biochemical and sophisticated imaging experiments are employed to delineate the molecular signaling cascades that are activated and required for long-lasting synaptic plasticity in the hippocampus , amygdala , cortex , and striatum , and whether these signaling events are required for memory formation , social behaviors , and behavioral flexibility . Klann 's laboratory also conducts electrophysiological , biochemical , imaging , and behavioral studies with various knockout and transgenic mice to determine how precise genetic manipulations that either activate or abolish signaling cascades alter synaptic function and behavior . Klann serves as a reviewing editor for The Journal of Neuroscience and as an associate editor for Neurobiology of Learning and Memory , and serves on the editorial boards of several other journals . He is a former member and chair of both the Neural Oxidative Metabolism & Death and the Molecular & Cellular Substrates of Complex Disorders Study Sections of the National Institutes of Health . Klann serves on the Scientific Advisory Boards of the Foundation for Angelman Syndrome Therapeutics and Pitt Hopkins Syndrome International Network . He also served on the Fragile X Outcomes Measures Group and the Fragile X Syndrome Research Plan Working Group of the National Institutes of Health . Klann also was the treasurer ( 2010-2012 ) and is the current president of the Molecular and Cellular Cognition Society . Klann received his Ph.D. from the Medical College of Virginia , did postdoctoral training at Baylor College of Medicine , and held faculty positions at the University of Pittsburgh ( 1994-2001 ) and Baylor College of Medicine ( 2001-2006 ) before joining the faculty of New York University in 2006 .", "qid": "558", "docid": "Eric_Klann", "rank": 56, "score": 71652 }, { "content": "Title: Plastic model Content: In art and architecture , plastic model may also be any three-dimensional physical model , regardless of material .

In order to model the stress-strain relation in these fluids , some fitting have been proposed such as the linear Bingham equation and the non-linear Herschel-Bulkley and Casson models . Analytical solutions exist for such models in simple flows . For general flow fields , it is necessary to develop numerical techniques to track down yielded/unyielded regions . This can be avoided by introducing into the models a continuation parameter , which facilitates the solution process and produces virtually the same results as the ideal models by the right choice of its value . Viscoplastic materials like slurries , pastes , and suspension materials have a yield stress , i.e. a critical value of stress below which they do not flow are also called Bingham plastics , after Bingham . Viscoplastic materials can be well approximated uniformly at all levels of stress as liquids that exhibit infinitely high viscosity in the limit of low shear rates followed by a continuous transition to a viscous liquid . This approximation could be made more and more accurate at even vanishingly small shear rates by means of a material parameter that controls the exponential growth of stress . Thus , a new impetus was given in 1987 with the publication by Papanastasiou of such a modification of the Bingham model with an exponential stress-growth term . The new model basically rendered the original discontinuous Bingham viscoplastic model as a purely viscous one , which was easy to implement and solve and was valid for all rates of deformation . The early efforts by Papanastasiou and his co-workers were taken up by the author and his coworkers , who in a series of papers solved many benchmark problems and presented useful solutions always providing the yielded/unyielded regions in flow fields of interest .

As a consequence , 18th century mathematicians believed that they could derive meaningful results by applying the usual rules of algebra and calculus that hold for finite expansions even when manipulating infinite expansions . In works such as Cours d'Analyse , Cauchy rejected the use of `` generality of algebra '' methods and sought a more rigorous foundation for mathematical analysis .

In the DRC , forests are cleared for agricultural purposes by utilizing slash and burn techniques . Aside from the visible depletion of resources , deforestation of the DRC also leads to a lost habit for the mountain gorilla among other rare species like the okapi , resulting in decreased biodiversity , soil erosion , and contribute to climate change . Since 1990 , the rate of deforestation in the DRC has remained constant at 0.20 % , which equates to the loss of 311,000 hectares , or roughly 1,200 square miles , annually . This amounts to destroying forests the size of Delaware every two years . The fact that the rate of deforestation has remained constant over the last twenty years is misleading as one might believe that government or non-government organizations ( NGO ) interventions have been responsible for the decline , but reports indicate otherwise . Three reasons have been postulated as to why deforestation rates have remained relatively low : 1 ) the road network within the country has been gradually in decline making access to more remote areas more difficult , 2 ) political and regulatory changes have disincentivized investment in the country , and 3 ) agriculture has expanded outside of forest areas . Additionally , while the rates remain constant , wood removal ( measured in cubic meters ) continues to dramatically increase annually . Industrialized roundwood has increased from 3.05 million cubic meters in 1990 to 4.45 million cubic meters in 2010 ; fuelwood has increased from 44.2 million cubic meters to 75.44 million cubic meters annually in that same time .

Disruption due to climate change , or other anthropogenic perturbations can result in decreased productivity and in some cases lead to disruptions in global biogeochemical cycles . The possible ramifications of changes in ecosystem biodiversity are not well characterized or understood , and it may be possible that disruption , up to a point , will have little to no effect given the redundancy within an ecosystem . This is particularly troubling in the context of microbial ecosystems . The dynamics of microbial ecosystems are tightly coupled to biogeochemical processes , and any perturbation within this system in particular could result in dramatic changes ( Kirchman , 2008 ) . For example , the microbial loop within the marine context is responsible for the decomposition of organics and recycling of nutrients back into the ecosystem . This allows for other organisms , such as phytoplankton , to reuse essential nutrients , like nitrogen , and continue production ( Kirchman 2008 ) . Without this recycled nitrogen , phytoplankton would be highly limited in their production rates , in turn limiting the growth of grazers . The effects of such an occurrence would reverberate throughout the food web , and nitrogen cycle . It is important to establish a base line of microbial diversity within ecosystems in order to gauge possible change due to climate change and the possible outcomes . Recent use of high-throughput sequencing techniques has broadened the scope of biodiversity , with the discovery of what has been titled the `` Rare Biosphere '' ( Sogin et al. , 2006 ) . Previous attempts to characterize in situ abundance have been made through pure culture and molecular techniques ( Fuhrman , 2009 ) . Pure culture providing a very narrow picture of some of the rarer species present , < 1-5 % of bacteria present ( Fuhrman , 2009 ) . Molecular techniques , such as Sanger sequencing , resulting in a much broader scope but highlighting the more abundant species present ( Heidelberg et al. , 2010 ) ( Pedros-Alio , 2007 ) . Neither technique captures all of the diversity present . Alternatively high throughput sequencing , `` tag sequencing '' , divides unique rRNA tag sequences into operational taxonomic units ( OTUs ) based upon similarities in mitochondrial-encoded cytochrome oxidases ( Sogin et al. , 2006 ) . Both Sanger , shot gun sequencing , and tag sequencing organize sequences into OTUs ( Heidelberg et al. , 2010 ) . However , it is the resolution that tag sequencing provides that sets it apart , resulting from the increased efficiency in serial analysis ( Heidelberg et al. , 2010 ) . This efficiency increase is made possible through the use of internal primer sequences resulting in restriction-digest overhanging sequences ( Heidelberg et al. , 2010 ) . Though OTUs provide a means of distinguishing the possible number of phylogenetic groups , it is not possible to deduce phylogenetic relationships based upon OTU 's . Tags associated with OTUs must be cross-referenced with gene banks , in order for tags to be phylotyped and relationships established ( Sogin et al. , 2006 ) . The result of tag sequencing has been to produce orders of magnitude larger estimates of OTUs present in ecosystems , producing a long tail on species abundance curves ( Patterson , 2009 ) ( Pedrós-Alío , 2007 ) . This long tail accounts for less than .1 % of the abundant species in a particular ecosystem . At the same time it represents thousands of populations accounting for most of the phylogenetic diversity in an ecosystem . This low-abundance high-diversity group is what is now called the `` Rare Biosphere '' . Using this method , Sogin et al. 's study of microbial diversity in North Atlantic deep water produced an estimate of 5266 different taxa ( Sogin et al. , 2006 ) . This is particularly dramatic considering that previous studies employing more traditional PCR cloning techniques have resulted in estimates of up to 500 ( Pedrós-Alío , 2007 ) .", "qid": "559", "docid": "Rare_biosphere", "rank": 9, "score": 107991 }, { "content": "Title: Ecological effects of biodiversity Content: The diversity of species and genes in ecological communities affects the functioning of these communities .

The current rate of extinction is sometimes considered a mass extinction , with current species extinction rates on the order of 100 to 1000 times as high as in the past . The two main areas where the effect of biodiversity on ecosystem function have been studied are the relationship between diversity and productivity , and the relationship between diversity and community stability .

Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction .

Upper Fremont Glacier is at an average altitude of 13450 ft and is one of the highest altitude glaciers in the American Rockies . Ice core samples were taken from Upper Fremont Glacier in 1990-1991 . These ice cores were analyzed for climatic changes as well as alterations of atmospheric chemicals . In 1998 an unbroken ice core sample of 538 ft was taken from the glacier and subsequent analysis of the ice showed an abrupt change in the oxygen isotope ratio oxygen-18 to oxygen-16 in conjunction with what is widely regarded as the end of the Little Ice Age , a period of cooler global temperatures between the years 1550 and 1850 . A linkage was established with a similar ice core study which had been undertaken on the Quelccaya Ice Cap in Peru , which also demonstrated the same changes in the oxygen isotope ratio during the same period . The climatic implications from the ice cores taken from both sites support evidence of a sudden global climate change during the mid 19th century . Ice cores from the glacier also showed increased levels of Tritium ( 3H ) and chlorine-36 around the year 1963 , which coincides with the peak period of above ground nuclear testing .

As air rises from sea level to the upper regions of the atmosphere the temperature decreases . The effect of mountain topography on prevailing winds is to force warm air from the lower region into an upper zone where it expands in volume at the cost of a proportionate loss of heat , often accompanied by the precipitation of moisture in the form of snow , rain or hail . The position of the Alps in the central European continent profoundly affects the climate of all the surrounding regions . The accumulation of vast masses of snow , which have gradually been converted into permanent glaciers , maintains a gradation of very different climates within the narrow space that intervenes between the foot of the mountains and their upper ridges ; it cools breezes that waft to the plains on either side , but its most important function is to regulate the water supply of the large region which is traversed by the streams of the Alps . Nearly all the moisture that is precipitated during fall , winter , and spring is stored in the form of snow and gradually diffused in the course of the succeeding summer ; even in the hottest and driest seasons the reserves accumulated during a long preceding period of years in the form of glaciers are available to maintain the regular flow of the greater streams . Nor is this all ; the lakes that fill several of the main valleys on the southern side of the Alps are somewhat above the level of the plains of Lombardy and Venetia , and afford an inexhaustible supply of water , which , from a remote period , has been used for that system of irrigation to which they owe their proverbial fertility . Six regions or zones , which are best distinguished by their characteristic vegetation , are found in the Alps .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change .

The greenhouse effect is caused by greenhouse gases that absorb sunlight . Energy from the sun that reaches Earth is either retained or sent into space . Greenhouse gases in Earth 's atmosphere such as carbon dioxide , methane , and water vapor absorb energy which cause a blanketing effect that warms the earth .

In July 2016 , scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor ( LUCA ) of all organisms living on Earth . The age of the Earth is about 4.54 billion years old . The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago , during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon . There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia . Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland . More recently , in 2015 , `` remains of biotic life '' were found in 4.1 billion-year-old rocks in Western Australia . According to one of the researchers , `` If life arose relatively quickly on Earth . . then it could be common in the universe . '' Since life began on Earth , five major mass extinctions and several minor events have led to large and sudden drops in biodiversity . The Phanerozoic eon ( the last 540 million years ) marked a rapid growth in biodiversity via the Cambrian explosion -- a period during which the majority of multicellular phyla first appeared . The next 400 million years included repeated , massive biodiversity losses classified as mass extinction events . In the Carboniferous , rainforest collapse led to a great loss of plant and animal life . The Permian -- Triassic extinction event , 251 million years ago , was the worst ; vertebrate recovery took 30 million years . The most recent , the Cretaceous -- Paleogene extinction event , occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the dinosaurs . The period since the emergence of humans has displayed an ongoing biodiversity reduction and an accompanying loss of genetic diversity . Named the Holocene extinction , the reduction is caused primarily by human impacts , particularly habitat destruction . Conversely , biodiversity impacts human health in a number of ways , both positively and negatively .

West of the 100th meridian , much of the US is semi-arid to desert in the far southwestern US , and Mediterranean along the California coast . East of the 100th meridian , the climate is humid continental in the northern areas east through New England , to humid subtropical in the Gulf and South Atlantic regions . Southern Florida is tropical , as is Hawaii and the US Virgin Islands . Higher-elevation areas of the Rocky Mountains , the Wasatch , Sierra Nevada , and Cascade Range are alpine . The West Coast areas in coastal Oregon and Washington are oceanic climate . The state of Alaska , on the northwestern corner of the North American continent , is largely subarctic climate , but with a subpolar oceanic climate in the southeast ( Alaska Panhandle ) , southwestern peninsula and Aleutian Islands . The primary drivers of weather in the contiguous United States are the seasonal change in the solar angle , the migration north/south of the subtropical highs , and the seasonal change in the position of the polar jet stream . In the Northern Hemisphere summer the Subtropical high pressure systems move northward and closer to the United States mainland . In the Atlantic Ocean , the `` Bermuda High '' creates a south-southwest flow of warm , humid air over the eastern , southern and central United States - resulting in warm to hot temperatures , high humidity and occasional thunderstorm activity . In the Pacific Ocean high pressure builds toward the California coast resulting in a northwesterly airflow creating the typical sunny , dry , and stable weather conditions along the West Coast . In the Northern Hemisphere winter , the subtropical highs retreat southward . The polar jet stream ( and associated conflict zone between cold , dry air masses from Canada and warm , moist air masses from the Gulf of Mexico ) drops further southward into the United States - bringing more precipitation and periods of disturbed weather , as well as colder or mild air masses . Areas in the southern US ( Florida , the Gulf Coast , the Desert Southwest , and southern California ) however , often have more stable weather , as the polar jet stream 's impact does not usually reach that far south . Weather systems , be they high-pressure systems ( anticyclones ) , low-pressure systems ( cyclones ) or fronts ( boundaries between air masses of differing temperature , humidity and most commonly , both ) are faster-moving and more intense in the winter/colder months than in the summer/warmer months , when the belt of lows and storms generally move into southern Canada . The Gulf of Alaska is the origination area of many storms that enter the United States . Such `` North Pacific lows '' enter the US through the Pacific Northwest , then move eastward across the northern Rocky Mountains , northern Great Plains , upper Midwest , Great Lakes and New England states . Across the central states from late fall to spring , `` Panhandle hook '' storms move from the central Rockies into the Oklahoma/Texas panhandle areas , then northeast toward the Great Lakes . They generate unusually large temperature contrasts , and often bring heavy Gulf moisture northward , resulting sometimes in cold conditions and possibly-heavy snow or ice north and west of the storm track , and warm conditions , heavy rains and potentially-severe thunderstorms south and east of the storm track - often simultaneously . Across the northern states in winter usually from Montana eastward , `` Alberta clipper '' storms track east and bring light to moderate snowfalls from the Great Lakes to New England , and often , windy and severe Arctic outbreaks behind them . When winter-season Canadian cold air masses drop unusually far southward , `` Gulf lows '' can develop in or near the Gulf of Mexico , then track eastward or northeastward across the Southern states , or nearby Gulf or South Atlantic waters . They often bring rain , but on rare occasions can bring ice to areas of the interior southern states . In the cold season ( generally November to March ) , most precipitation occurs in conjunction with organized low-pressure systems and associated fronts . In the summer , storms are much more localized , with short-duration thunderstorms common in many areas east of the 100th meridian . In the warm season , storm systems affecting a large area are less frequent , and weather conditions are more solar -LCB- sun -RCB- controlled , with the greatest chance for thunderstorm and severe weather activity during peak heating hours , mostly between 3 PM and 9 PM local time . From May to August especially , often-overnight mesoscale-convective-system ( MCS ) thunderstorm complexes , usually associated with frontal activity , can deliver significant to flooding rainfall amounts from the Dakotas/Nebraska eastward across Iowa/Minnesota to the Great Lakes states . From late summer into fall ( mostly August to October ) , tropical cyclones sometimes approach or cross the Gulf and Atlantic states , bringing high winds , heavy rainfall , and storm surges ( often topped with battering waves ) to coastal areas .", "qid": "559", "docid": "Climate_of_the_United_States", "rank": 50, "score": 91851 }, { "content": "Title: Land use, land-use change and forestry Content: Land use , land-use change and forestry ( LULUCF ) is defined by the United Nations Climate Change Secretariat as a `` greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use , land-use change and forestry activities .

Alpine pastures are typically below 2,400 m but may exceptionally be located as high as 2,800 m. ) . The High Alps have tundra or ice cap climate rather than the Alpine climate eponymous of the Alpine region at 1,800-2 ,500 m , above the tree-line but still amenable to transhumance economy . Exploration of the High Alps began in the 18th century , with Horace-Bénédict de Saussure . The first ascent of the highest peak of the alps , Mont Blanc , dates to 1786 . All important mountain passes in Switzerland are below 2,500 m ( with Nufenen Pass as high as 2,478 m ) but there are a few minor foot passes above 3,000 m : Schöllijoch at 3,343 m , Theodul Pass at 3,301 m , Zwischbergen Pass at 3,268 m , and others . Of historical interest is the Schnidejoch at 2,756 m which appears to have served as a pass since prehistoric times . In other Alpine countries there are higher road passes , such as the Col de l'Iseran ( the highest paved road in Europe ) in France and the Stelvio Pass in Italy . The alpine line of perpetual snow is not fixed . The occurrence of favorable meteorological conditions during several successive seasons can increase the extent of the snowfields and lower the limit of seemingly permanent snow , while the opposite may cause the limit to rise higher on the flanks of the mountains . In some parts of the Alps the limit is about 2,400 m elevation , while in others it can not be placed much below 2,900 m . As very little snow remains on rocks angled more than 60 ° , this is soon removed by the wind , some steep masses of rock remain bare even near the summits of the highest peaks , but as almost every spot offering the least hold for vegetation is covered with snow , few flowering plants are seen above 3,350 m. The climate of the glacial region has often been compared to that of the polar regions , but they are very different . Here , intense solar radiation by day , which raises the surface when dry to a temperature approaching 27 ° C , alternates with severe frost by night . There , the Sun , which never sets is only able to send feeble rays that maintain a low temperature , rarely rising more than a few degrees above the freezing point .

Feedback in general is the process in which changing one quantity changes a second quantity , and the change in the second quantity in turn changes the first . Positive feedback amplifies the change in the first quantity while negative feedback reduces it . The term `` forcing '' means a change which may `` push '' the climate system in the direction of warming or cooling . An example of a climate forcing is increased atmospheric concentrations of greenhouse gases . By definition , forcings are external to the climate system while feedbacks are internal ; in essence , feedbacks represent the internal processes of the system . Some feedbacks may act in relative isolation to the rest of the climate system ; others may be tightly coupled ; hence it may be difficult to tell just how much a particular process contributes . Forcings , feedbacks and the dynamics of the climate system determine how much and how fast the climate changes . The main positive feedback in global warming is the tendency of warming to increase the amount of water vapor in the atmosphere , which in turn leads to further warming . The main negative feedback comes from the Stefan -- Boltzmann law , the amount of heat radiated from the Earth into space changes with the fourth power of the temperature of Earth 's surface and atmosphere . Some observed and potential effects of global warming are positive feedbacks , which contribute directly to further global warming .

Loss and damage can result from sudden-onset events ( climate disasters , such as cyclones ) as well as slow-onset processes ( such as sea level rise ) . Loss and damage can occur in human systems ( such as livelihoods ) as well as natural systems ( such as biodiversity ) , though the emphasis in research and policy is on human impacts . Within the realm of loss and damage to human systems , a distinction is made between economic losses and non-economic losses . The main difference between the two is that non-economic losses involve things that are not commonly traded in markets . At the 18th Conference of the Parties meeting of the UNFCCC in 2012 in Doha , Qatar , it took 36 hours of negotiation between 195 nations to arrive at a plan to address loss and damage associated with adverse effects of climate change particularly in countries most vulnerable to climate change . A new website was launched at the conference by the Loss and Damage Vulnerable Countries Initiative . It described its aim as being `` the first dedicated site for news , resources and opinion on the issue of loss and damage associated with the adverse impacts of climate change '' . Examples of types of loss and damage include farmers who can no longer grow crops to eat , or grass to feed cattle , because their soil has become too salty , and fishermen who have lost their livelihoods because rivers have dried up . In popular press , and in statements by some parties in the climate negotiations , the terms loss and damage is often associated with liability and compensation . This explains why the topic raises heated debates , and tends to widen the divide between developed countries , which are historically responsible for most greenhouse gas emissions , and developing countries that are more vulnerable to impacts of climate change . For vulnerable countries , loss and damage is most of all about recognizing that past and current efforts to avoid dangerous climate change , and that there are limits and constraints to adaptation . The United Nations Framework Convention on Climate Change has developed a work programme on loss and damage which aims to find ways to address the issue in developing countries that are particularly vulnerable to the adverse effects of climate change . On 12 -- 14 September 2013 , it held a meeting in Fiji to consider how best to address loss and damage from ` slow-onset events ' . These are impacts of climate change that occur over time , such as sea-level rise , rather than in a single , destructive event . Bangladesh is already suffering from loss and damage resulting from sea-level rise , due to its flat terrain in the coastal region . At the 19th Conference of the Parties meeting of the UNFCCC in 2013 in Warsaw , Poland , the Warsaw International Mechanism for Loss and Damage associated with Climate Change Impacts was established . At the 20th Conference of the Parties in Lima , Peru ( 2014 ) , the work plan of the executive committee of the Warsaw International Mechanism was approved . The 5th Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) , published in 2013-2014 had no separate chapter on loss and damage , but WG2 Chapter 16 about adaptation limits and constraints , is very relevant for people interested in loss and damage . A qualitative data analysis ( QDA ) of what the IPCC 5th Assessment Report has to say about loss and damage surprisingly showed that the term was used much more often in statements about Annex 1 countries ( e.g. US , Australia or European countries ) than in text about non-Annex 1 countries ( most countries in Africa , Asia Latin America and the Pacific ) , which tend to be more vulnerable to impacts of climate change .

It is named after an indicator genus , the alpine-tundra wildflower Dryas octopetala . Leaves of Dryas octopetala are occasionally abundant in the Late Glacial , often minerogenic-rich , like the lake sediments of Scandinavian lakes . The Younger Dryas saw a sharp decline in temperature over most of the northern hemisphere , at the end of the Pleistocene epoch , immediately before the current warmer Holocene . It was the most recent and longest of several interruptions to the gradual warming of the Earth 's climate since the severe Last Glacial Maximum , c. 27,000 to 24,000 calendar years BP . The change was relatively sudden , taking place in decades , and resulted in a decline of 2 to 6 degrees Celsius , advances of glaciers and drier conditions , over much of the temperate northern hemisphere . It is thought to have been caused by a decline in the strength of the Atlantic meridional overturning circulation , which transports warm water from the equator towards the North Pole , and which in turn is thought to have been caused by an influx of fresh cold water from North America into the Atlantic . The Younger Dryas was a period of climatic change , but the effects were complex and variable . In the southern hemisphere , and some areas of the north such as southeastern North America , there was a slight warming . The presence of a distinct cold period at the end of the Late Glacial interval has been known for a long time . Paleobotanical and lithostratigraphic studies of Swedish and Danish bog and lake sites , e.g. the Allerød clay pit in Denmark , first recognized and described the Younger Dryas . The Younger Dryas is the youngest and longest of three stadials that resulted from typically abrupt climatic changes that took place over the last 16,000 calendar years . Within the Blytt-Sernander classification of north European climatic phases , the prefix ` Younger ' refers to the recognition that this original ` Dryas ' period was preceded by a warmer stage , the Allerød oscillation , which in turn was preceded by the Older Dryas around 14,000 calendar years BP . This is not securely dated , and estimates vary by 400 years , but it is generally accepted that it lasted around 200 years . In northern Scotland the glaciers were thicker and more extensive than during the Younger Dryas . The Older Dryas , in turn , is preceded by another warmer stage , the Bølling oscillation that separates it from a third and even older stadial . This stadial is often , but not always , known as the Oldest Dryas . The Oldest Dryas occurred approximately 1,770 calendar years before the Younger Dryas and lasted about 400 calendar years . According to the GISP2 ice core from Greenland , the Oldest Dryas occurred between about 15,070 and 14,670 calendar years BP . In Ireland , the Younger Dryas has also been known as the Nahanagan Stadial , while in Great Britain it has been called the Loch Lomond Stadial . In the Greenland Summit ice core chronology , the Younger Dryas corresponds to Greenland Stadial 1 ( GS-1 ) .

The term is sometimes used in a narrow sense , such as when describing the loss of particular alleles or genes , as well as being used more broadly , as when referring to the loss of a phenotype or whole species . Genetic erosion occurs because each individual organism has many unique genes which get lost when it dies without getting a chance to breed . Low genetic diversity in a population of wild animals and plants leads to a further diminishing gene pool -- inbreeding and a weakening immune system can then `` fast-track '' that species towards eventual extinction . By definition , endangered species suffer varying degrees of genetic erosion . Many species benefit from a human-assisted breeding program to keep their population viable , thereby avoiding extinction over long time-frames . Small populations are more susceptible to genetic erosion than larger populations . Genetic erosion gets compounded and accelerated by habitat loss and habitat fragmentation -- many endangered species are threatened by habitat loss and ( fragmentation ) habitat . Fragmented habitat create barriers in gene flow between populations . The gene pool of a species or a population is the complete set of unique alleles that would be found by inspecting the genetic material of every living member of that species or population .

Though first attempted in the 1920s , it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic results . A number of global and regional forecast models are run in different countries worldwide , using current weather observations relayed from radiosondes , weather satellites and other observing systems as inputs . Mathematical models based on the same physical principles can be used to generate either short-term weather forecasts or longer-term climate predictions ; the latter are widely applied for understanding and projecting climate change . The improvements made to regional models have allowed for significant improvements in tropical cyclone track and air quality forecasts ; however , atmospheric models perform poorly at handling processes that occur in a relatively constricted area , such as wildfires . Manipulating the vast datasets and performing the complex calculations necessary to modern numerical weather prediction requires some of the most powerful supercomputers in the world . Even with the increasing power of supercomputers , the forecast skill of numerical weather models extends to only about six days . Factors affecting the accuracy of numerical predictions include the density and quality of observations used as input to the forecasts , along with deficiencies in the numerical models themselves . Post-processing techniques such as model output statistics ( MOS ) have been developed to improve the handling of errors in numerical predictions . A more fundamental problem lies in the chaotic nature of the partial differential equations that govern the atmosphere . It is impossible to solve these equations exactly , and small errors grow with time ( doubling about every five days ) . Present understanding is that this chaotic behavior limits accurate forecasts to about 14 days even with perfectly accurate input data and a flawless model . In addition , the partial differential equations used in the model need to be supplemented with parameterizations for solar radiation , moist processes ( clouds and precipitation ) , heat exchange , soil , vegetation , surface water , and the effects of terrain . In an effort to quantify the large amount of inherent uncertainty remaining in numerical predictions , ensemble forecasts have been used since the 1990s to help gauge the confidence in the forecast , and to obtain useful results farther into the future than otherwise possible .

The project was funded by the National Science Foundation as part of the International Decade of Ocean Exploration ( 1970s ) and is based in large part of the collection and analysis of a very large number of sediment cores to create a snapshot of conditions across the oceans . The CLIMAP project also resulted in maps of vegetative zones across the continents and the estimated extent of glaciation at the time . Most CLIMAP results aim to describe the Earth as it was 18 thousand years ago , but there was also an analysis to look at conditions during the previous interglacial -- 120 thousand years ago ( CLIMAP 1981 ) . CLIMAP has been a cornerstone of paleoclimate research and remains the most used sea surface temperature reconstruction of the global ocean during the last glacial maximum ( Yin and Battisti 2001 ) , but it has also been persistently controversial . CLIMAP resulted in estimates of global cooling of only 3.0 ± 0.6 ° C relative to the modern day ( Hoffert and Covey 1992 ) . The climate change during an ice age that occurs far from the continental ice sheets themselves is believed to be primarily controlled by changes in greenhouse gases , hence the conditions during the last glacial maximum provide a natural experiment for measuring the impact of changes in greenhouse gases on climate . The cited estimates of 3.0 ° C implies a climate sensitivity to carbon dioxide changes at the low end of the range proposed by the Intergovernmental Panel on Climate Change . However , CLIMAP also suggested that some of the tropics and in particular much of the Pacific Ocean were warmer than they are today . To date , no climate model has been able to reproduce the proposed warming in the Pacific ( Yin and Battisti 2001 ) , with most preferring a several degree cooling . Also , it appears that climate models which are forced to match the CLIMAP sea surface measurements are too warm to match estimates for changes at continental locations ( Pinot et al. 1999 ) . This suggests that either climate model design is missing some important unknown factor , or CLIMAP systematically overestimated the temperatures in the tropical oceans during the last glacial , though there is at present no consistent explanation for why or how this should have happened . Unfortunately cost and difficulty of collecting sediment cores from the open Pacific has limited the availability of samples that might help to confirm or disprove these observations .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation . In some areas , policies designed to address global warming may contribute positively towards other development objectives . In other areas , the cost of global warming policies may divert resources away from other socially and environmentally beneficial investments ( the opportunity costs of climate change policy ) .", "qid": "562", "docid": "Economics_of_global_warming", "rank": 23, "score": 83927 }, { "content": "Title: Climate change in Argentina Content: According to scientists , global warming is predicted to have significant effects on the climate of Argentina .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

Human beings have attempted to predict the weather informally for millennia , and formally since the nineteenth century . Weather forecasts are made by collecting quantitative data about the current state of the atmosphere at a given place and using scientific understanding of atmospheric processes to project how the atmosphere will change . Once an all-human endeavor based mainly upon changes in barometric pressure , current weather conditions , and sky condition , weather forecasting now relies on computer-based models that take many atmospheric factors into account . Human input is still required to pick the best possible forecast model to base the forecast upon , which involves pattern recognition skills , teleconnections , knowledge of model performance , and knowledge of model biases . The inaccuracy of forecasting is due to the chaotic nature of the atmosphere , the massive computational power required to solve the equations that describe the atmosphere , the error involved in measuring the initial conditions , and an incomplete understanding of atmospheric processes . Hence , forecasts become less accurate as the difference between current time and the time for which the forecast is being made ( the range of the forecast ) increases . The use of ensembles and model consensus help narrow the error and pick the most likely outcome . There are a variety of end uses to weather forecasts . Weather warnings are important forecasts because they are used to protect life and property . Forecasts based on temperature and precipitation are important to agriculture , and therefore to traders within commodity markets . Temperature forecasts are used by utility companies to estimate demand over coming days . On an everyday basis , people use weather forecasts to determine what to wear on a given day .

The greenhouse effect is caused by greenhouse gases that absorb sunlight . Energy from the sun that reaches Earth is either retained or sent into space . Greenhouse gases in Earth 's atmosphere such as carbon dioxide , methane , and water vapor absorb energy which cause a blanketing effect that warms the earth . Aerosols such as black carbon also catalyze the warming effect as they are unreflective and absorb energy from the sun supplementing greenhouse gases in the warming effect . These combined factors are warming the Earth 's land as well as the oceans . Many fish species possess a certain range of water temperature that they are able to tolerate which is causing species to migrate to different areas where the water temperature is livable .

These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end . These periods are caused by variations in eccentricity , axial tilt , and precession of the Earth 's orbit . As part of the ongoing supercontinent cycle , plate tectonics will probably result in a supercontinent in 250 -- 350 million years . Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present . This will cause the atmosphere to become a `` moist greenhouse '' , resulting in a runaway evaporation of the oceans . As a likely consequence , plate tectonics will come to an end , and with them the entire carbon cycle . Following this event , in about 2 − 3 billion years , the planet 's magnetic dynamo may cease , causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere . Four billion years from now , the increase in the Earth 's surface temperature will cause a runaway greenhouse effect , heating the surface enough to melt it . By that point , all life on the Earth will be extinct . The most probable fate of the planet is absorption by the Sun in about 7.5 billion years , after the star has entered the red giant phase and expanded to cross the planet 's current orbit .", "qid": "562", "docid": "Future_of_Earth", "rank": 33, "score": 80690 }, { "content": "Title: Global warming hiatus Content: A global warming hiatus , also sometimes referred to as a global warming pause or a global warming slowdown , is a period of relatively little change in globally averaged surface temperatures . In the current episode of global warming many such 15-year periods appear in the surface temperature record , along with robust evidence of the long-term warming trend ; climate is classically averaged over 30-year periods . Publicity has surrounded claims of a global warming hiatus during the period 1998 -- 2013 . The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend , and so subsequent annual temperatures gave the appearance of a hiatus : by January 2006 , it appeared to some that global warming had stopped or paused . A 2009 study showed that decades without warming were not exceptional , and in 2011 a study showed that if allowances were made for known variability , the rising temperature trend continued unabated . There was increased public interest in 2013 in the run-up to publication of the IPCC Fifth Assessment Report , and despite concerns that a 15-year period was too short to determine a meaningful trend , the IPCC included a section on a hiatus , which it defined as a much smaller increasing linear trend over the 15 years from 1998 to 2012 , than over the 60 years from 1951 to 2012 . Various studies examined possible causes of the short-term slowdown . Even though the overall climate system has continued to accumulate energy due to Earth 's positive energy budget , the available temperature readings at the Earth 's surface indicate slower rates of increase in surface warming than in the prior decade . Since measurements at the top of the atmosphere show that Earth is receiving more energy than it is radiating back into space , the retained energy should be producing warming in the Earth 's climate system . Research reported in July 2015 on an updated NOAA dataset casts doubt on the existence of a hiatus , and it finds no indication of a slowdown even in earlier years . Scientists working on other datasets welcomed this study , though they have expressed the view that the recent warming trend was less than in previous periods of the same length . Subsequently , a detailed study supports the conclusion that warming is continuing , but it also find there was less warming between 2001 and 2010 than climate models had predicted , and that this slowdown might be attributed to short-term variations in the Pacific decadal oscillation ( PDO ) , which was negative during that period . Another review finds `` no substantive evidence '' of a pause in global warming . A statistical study of global temperature data since 1970 concludes that the term ` hiatus ' or ` pause ' is not justified . Independent of these discussions about data and measurements for earlier years , 2015 turned out to be much warmer than any of the earlier years , already before El Niño conditions started . The warmth of 2015 largely ended any remaining scientific credibility of claims that the supposed `` hiatus '' since 1998 had any significance for the long-term warming trend . In January 2017 , a study published in the journal Science Advances cast further doubt on the existence of a recent pause , with more evidence that ocean temperatures have been underestimated . An April 2017 study found the data consistent with a steady warming trend globally since the 1970s , with fluctuations within the expected range of short term variability .", "qid": "562", "docid": "Global_warming_hiatus", "rank": 34, "score": 80598 }, { "content": "Title: Tim Palmer (physicist) Content: Timothy Noel Palmer CBE FRS ( born 31 December 1952 ) is a mathematical physicist by training .

Australia is vulnerable to the effects of global warming projected for the next 50 to 100 years because of its extensive arid and semi-arid areas , an already warm climate , high annual rainfall variability , and existing pressures on water supply . The continent 's high fire risk increases this susceptibility to change in temperature and climate .

The impacts of climate change in Australia will be complex and to some degree uncertain , but increased foresight may enable the country to safeguard its future through planned mitigation and adaptation .

His research greatly influenced global and regional climate change studies including development of breakthrough reanalysis and downscaling datasets and weather forecasting studies . He was the co-author of one of the most cited geophysics paper in his time . Kanamitsu was born in 1943 and was raised in Sapporo . He did his B.S. and M. Sc . in 1968 at Hokkaido University , Japan and M.Sc . and Ph. D. in 1975 at Florida State University . He was one of the large group of Japanese scientists who after the World War II greatly contributed to the development of the dynamic meteorology in the US and in the World including Syukuro Manabe , Taroh Matsuno , Kikuro Miyakoda , and Akio Arakawa . He served as a Forecaster at Japan Meteorological Agency , as a leader of the Global Modeling Branch , Development Division , and later as an Acting Chief of the Prediction Branch at the Climate Prediction Center of the National Meteorological Center . In 2001 he moved to Scripps Institution of Oceanography where he worked to the rest of his life . He had a group of young researchers working with him . Kanamitsu was instrumental in creating one of the most successful datasets used in global change studies - the NCEP/NCAR Reanalysis for which he received a Group Gold Medal from the Department of Commerce in 1997 . His 1996 reanalysis paper is one of the most celebrated paper in atmospheric science and geosciences - at the time of his death this paper was cited 7985 times . His publications report ambitious , multiyear in making , and extensive project to develop regional-scale climate change dataset based on the NCEP -- NCAR reanalysis for the period 1948 -- 2005 . This downscaling paved the way for local scale understanding of climate changes . In he worked out a problem of how to produce meteorological dataset such as winds , pressures , or temperature on fine scale ( say every 10 km ) if the measurements are performed every 200 km . This led to a concept of dynamical downscaling of climate analysis using regional models . He served as an editor for the Journal of the Meteorological Society of Japan ( 1980 -- 1985 ) and the Monthly Weather Review ( 1991 -- 1993 ) .

In the scientific literature , there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases . No scientific body of national or international standing disagrees with this view , though a few organizations with members in extractive industries hold non-committal positions . Disputes over the key scientific facts of global warming are more prevalent in the media than in the scientific literature , where such issues are treated as resolved , and such disputes are more prevalent in the United States than globally . Political and popular debate concerning the existence and cause of climate change includes the reasons for the increase seen in the instrumental temperature record , whether the warming trend exceeds normal climatic variations , and whether human activities have contributed significantly to it . Scientists have resolved these questions decisively in favour of the view that the current warming trend exists and is ongoing , that human activity is the cause , and that it is without precedent in at least 2000 years . Public disputes that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases ( climate sensitivity ) , how global climate change will play out at local and regional scales , and what the consequences of global warming will be . Global warming remains an issue of widespread political debate , often split along party political lines , especially in the United States .

It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide . A GWP is calculated over a specific time interval , commonly 20 , 100 , or 500 years . GWP is expressed as a factor of carbon dioxide ( whose GWP is standardized to 1 ) . In the Fifth Assessment Report of the Intergovernmental Panel on Climate Change , methane has a lifetime of 12.4 years and with climate-carbon feedbacks a global warming potential of 86 over 20 years and 34 over 100 years in response to emissions . User related choices such as the time horizon can greatly affect the numerical values obtained for carbon dioxide equivalents . For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph . Because the GWP of a greenhouse gas depends directly on its infrared spectrum , the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change .", "qid": "562", "docid": "Global_warming_potential", "rank": 53, "score": 75997 }, { "content": "Title: Environmental Modeling Center Content: The Environmental Modeling Center ( EMC ) improves numerical weather , marine and climate predictions at the National Centers for Environmental Prediction ( NCEP ) , through a broad program of research in data assimilation and modeling .

It originates in the western North Pacific around 20 ° N , and flows eastward against the northeast trade winds and stretches northeastward to the north of Hawaii . It is accompanied by a subsurface temperature and density front called the subtropical front , in thermal wind relation with the STCC . Furthermore , the STCC maintains a sea surface temperature front during winter and spring . During April and May when the SST front is still strong , the seasonal warming makes the region conductive to atmospheric convection , and surface wind stress curls turn weakly positive along the front on the background of negative curls that drive the subtropical gyre . On the weather timescale , positive wind curls are related to low-pressure systems of a subsynoptic scale in space , energized by surface baroclinicity and latent heat release along the STF front . The SST front also anchors a meridional maximum in column-integrated water vapor , indicating a deep structure of the atmosphere response .", "qid": "562", "docid": "Subtropical_Countercurrent", "rank": 71, "score": 73963 }, { "content": "Title: Joseph D'Aleo Content: Joseph D'Aleo is a Certified Consultant meteorologist and the first Director of Meteorology at The Weather Channel .

It was the 21st yearly session of the Conference of the Parties ( COP ) to the 1992 United Nations Framework Convention on Climate Change ( UNFCCC ) and the 11th session of the Conference of the Parties ( CMP ) to the 1997 Kyoto Protocol . The conference negotiated the Paris Agreement , a global agreement on the reduction of climate change , the text of which represented a consensus of the representatives of the 196 parties attending it . The agreement will enter into force when joined by at least 55 countries which together represent at least 55 percent of global greenhouse emissions . On 22 April 2016 ( Earth Day ) , 174 countries signed the agreement in New York , and began adopting it within their own legal systems ( through ratification , acceptance , approval , or accession ) . According to the organizing committee at the outset of the talks , the expected key result was an agreement to set a goal of limiting global warming to less than 2 degrees Celsius ( ° C ) compared to pre-industrial levels . The agreement calls for zero net anthropogenic greenhouse gas emissions to be reached during the second half of the 21st century . In the adopted version of the Paris Agreement , the parties will also `` pursue efforts to '' limit the temperature increase to 1.5 ° C . The 1.5 ° C goal will require zero emissions sometime between 2030 and 2050 , according to some scientists . Prior to the conference , 146 national climate panels publicly presented draft national climate contributions ( called `` Intended Nationally Determined Contributions '' , INDCs ) . These suggested commitments were estimated to limit global warming to 2.7 degrees Celsius by 2100 . For example , the EU suggested INDC is a commitment to a 40 percent reduction in emissions by 2030 compared to 1990 . The agreement establishes a `` global stocktake '' which revisits the national goals to `` update and enhance '' them every five years beginning 2023 . However , no detailed timetable or country-specific goals for emissions were incorporated into the Paris Agreement -- as opposed to the previous Kyoto Protocol . A number of meetings took place in preparation for COP21 , including the Bonn Climate Change Conference , 19 to 23 October 2015 , which produced a draft agreement .", "qid": "564", "docid": "2015_United_Nations_Climate_Change_Conference", "rank": 1, "score": 203725 }, { "content": "Title: Paris Agreement Content: The Paris Agreement ( Accord de Paris ) is an agreement within the United Nations Framework Convention on Climate Change ( UNFCCC ) dealing with greenhouse gas emissions mitigation , adaptation and finance starting in the year 2020 .

In accordance with Article 28 of the Paris Agreement, a country cannot give notice of withdrawal from the agreement before three years of its start date in the relevant country, which was on November 4, 2016 in the case of the United States. The White House later clarified that the U.S. will abide by the four-year exit process. On November 4, 2019, the administration gave a formal notice of intention to withdraw, which takes 12 months to take effect.

The lower defining point , 0 ° F , was established as the temperature of a solution of brine made from equal parts of ice and salt . Further limits were established as the melting point of ice ( 32 ° F ) and his best estimate of the average human body temperature ( 96 ° F , about 2.6 ° F less than the modern value due to a later redefinition of the scale ) . The scale is now usually defined by two fixed points : the temperature at which water freezes into ice is defined as 32 ° F , and the boiling point of water is defined to be 212 ° F , a 180 ° F separation , as defined at sea level and standard atmospheric pressure . By the end of the 20th century , Fahrenheit was used as the official temperature scale only in the United States ( including its unincorporated territories ) , its freely associated states in the Western Pacific ( Palau , the Federated States of Micronesia and the Marshall Islands ) , the Bahamas , Belize , and the Cayman Islands .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

The Kyoto Protocol was adopted in Kyoto , Japan , on 11 December 1997 and entered into force on 16 February 2005 . There are currently 192 parties ( Canada withdrew effective December 2012 ) to the Protocol . The Kyoto Protocol implemented the objective of the UNFCCC to fight global warming by reducing greenhouse gas concentrations in the atmosphere to `` a level that would prevent dangerous anthropogenic interference with the climate system '' ( Art. 2 ) . The Protocol is based on the principle of common but differentiated responsibilities : it puts the obligation to reduce current emissions on developed countries on the basis that they are historically responsible for the current levels of greenhouse gases in the atmosphere . The Protocol 's first commitment period started in 2008 and ended in 2012 . A second commitment period was agreed on in 2012 , known as the Doha Amendment to the protocol , in which 37 countries have binding targets : Australia , the European Union ( and its 28 member states ) , Belarus , Iceland , Kazakhstan , Liechtenstein , Norway , Switzerland , and Ukraine .

When the boy gets the flu , a doctor is called in and recommends three different medicines and tells the boy 's father that his temperature is 102 degrees Fahrenheit ( 39 degrees Celsius ) . He is very quiet and depressed , finally asking when he will die ; he had thought that a 102 degree temperature was lethal because he heard in France ( where Celsius is used ) that one can not live with a temperature over 44 degrees . When the father explains to him the difference in scales , the boy slowly relaxes , and the next day , `` he cried very easily at little things that were of no importance . '' The story ´ s theme is the boy 's misunderstanding leading to the fear of his death without his father realizing this . analysis : a ) A fateful misunderstanding The misunderstanding between father and son exists because they do not have the same thoughts . The boy thinks he will die but the father thinks his son is only ill . The boy uses the word `` it '' to describe the process of dying . The father also uses the word `` it '' , but to describe that it is no problem for him to stay at home with his son . Since they only use the pronoun `` it '' neither of them knows what the other person is talking about . b ) The hunting scene The landscape is described as frozen because it 's a cold day . The father 's behaviour is also cold because he is shooting birds and killing them . The father 's inability to understand his son is symbolically expressed by the layer of ice separating him from nature ( he is helpless on the icy surface ) ; the same helplessness applies to his relationship to his son . c ) Interdependence between theme and point of view The theme focuses on the misunderstanding between father and son , which is disastrous for the son due to the lack of knowledge as far as the different scales are concerned . The failure in communication leads to the son ´ s being afraid of dying . This is why Hemingway chooses the first person narrator with a limited point of view . He is therefore confined to presenting mere observations and suppositions . `` The boy was evidently holding tight onto himself about something '' , which is only one example of the father ´ s suppositions . The father is only an observer of the scene without realizing the son ´ s fears . He remains detached and can not imagine and feel the son ´ s distress . An observer narrator is the best way of expressing this distance between the two . Hemingway cleverly chooses this point of view as one means of showing the lack of mutual closeness in the relationship between father and son .

President Barack Obama committed in the December 2009 Copenhagen Climate Change Summit to reduce carbon dioxide emissions in the range of 17 % below 2005 levels by 2020 , 42 % below 2005 levels by 2030 , and 83 % below 2005 levels by 2050 . In an address towards the U.S. Congress in June 2013 , Obama detailed a specific action plan to achieve the 17 % carbon emissions cut from 2005 by 2020 . He included such measures as shifting from coal-based power generation to solar and natural gas production . Climate change is seen as a national security threat to the United States . In 2015 , according to The New York Times and others , oil companies knew that burning oil and gas could cause global warming since the 1970s but , nonetheless , funded deniers for years . 2016 was an historic year for billion-dollar weather and climate disasters in U.S.", "qid": "564", "docid": "Climate_change_in_the_United_States", "rank": 46, "score": 106845 }, { "content": "Title: European Climate Change Programme Content: The European Climate Change Programme ( ECCP ) was launched in June 2000 by the European Union 's European Commission , with the purpose of avoiding dangerous climate change .

The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise . The balance of impacts of global warming become significantly negative at larger values of warming .

It concluded `` with a high level of confidence that global mean surface temperature was higher during the last few decades of the 20th century than during any comparable period during the preceding four centuries '' , justified by consistent evidence from a wide variety of geographically diverse proxies , but `` Less confidence can be placed in large-scale surface temperature reconstructions for the period from 900 to 1600 '' . It broadly agreed with the basic findings of the original MBH studies , which subsequently been supported by other reconstructions and proxy records , while emphasising uncertainties over earlier periods .

The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases , especially carbon dioxide . When the global temperature changes , the changes in climate are not expected to be uniform across the Earth . In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores . Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years . There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere . The coast can also be considered a region , and will suffer severe impacts from sea level rise .", "qid": "564", "docid": "Regional_effects_of_global_warming", "rank": 73, "score": 101039 }, { "content": "Title: Paris Conference Content: Paris Conference may refer to : Paris Conference on Passports & Customs Formalities and Through Tickets ( 1920 ) Paris Economic Conference ( 1916 ) Paris Peace Accords ( 1973 ) 2015 United Nations Climate Change Conference , held in Paris Paris Peace Conference ( disambiguation )", "qid": "564", "docid": "Paris_Conference", "rank": 74, "score": 100961 }, { "content": "Title: Paris Economy Pact Content: Paris Economy Pact was an international economic agreement reached at the Paris Economic Conference held from 14 June 1916 in Paris , France .

It has been endorsed internationally by governments in different arenas , including the International Labour Organisation ( ILO ) , which adopted conclusions on this matter in 2013 and tripartite ( union-employer-government ) `` Guidelines on a Just Transition towards environmentally-sustainable economies and societies for all '' in 2015 . The Paris Climate Agreement also contains references to a Just Transition , where government commit to ensure that workers are accompanied in the transformation through the creation of decent work opportunities . The rationale for a Just Transition comes from evidence that shows that if millions of jobs can be created out of the transformation towards a clean economy , some sectors such as energy extraction and production , manufacturing , agriculture and forestry , just to mention a few , which employ today millions of workers will undergo dramatic restructuring . Just Transition policies should be therefore deployed to ensure that there is strong public support for environmental action . There is a concern that significant periods of economic restructuring in the past have often happened in a chaotic fashion leaving ordinary workers , their families and communities to bear the brunt of the transition to new ways of producing wealth , leading to unemployment , poverty and exclusion . Just Transition policies For trade unions , `` Just Transition '' describes the transition towards a low‐carbon and climate‐resilient economy that maximises the benefits of climate action while minimising hardships for workers and their communities . Needs will vary in different countries , though some policies must be applied everywhere . These include : Sound investments in low‐emission and job-rich sectors and technologies . These investments must be undertaken through due consultation with all those affected , respecting human and labour rights , and Decent Work principles . Social dialogue and democratic consultation of social partners ( trade unions and employers ) and other stakeholders ( i.e. communities ) . Research and early assessment of the social and employment impacts of climate policies.Training and skills development , which are key to support the deployment of new technologies and foster industrial change . Social protection , along with active labour markets policies . Local economic diversification plans that support decent work and provide community stability in the transition . Communities should not be left on their own to manage the impacts of the transition as this will not lead to a fair distribution of costs and benefits . Definition and evolution of the Just Transition concept A summary of this evolution is contained in an article published by the International Journal on Labour Research In 1998 , a Canadian union activist , Brian Kohler , published what was going to become one of the first mentions of the Just Transition concept in a union newsletter . It constituted an attempt to reconcile the union movement 's efforts to provide workers with decent jobs and the need to protect the environment . As Kohler had clearly stated previously : `` The real choice is not jobs or environment . It is both or neither . '' In ten years , the union movement perception of environmental challenges has evolved and with it the definition , boundaries and scope of the `` just transition '' needed . Today , `` Just Transition '' can be understood as the conceptual framework in which the labour movement captures the complexities of the transition towards a low-carbon and climate-resilient economy , highlighting public policy needs and aiming to maximize benefits and minimize hardships for workers and their communities in this transformation . In a document prepared by the International Trade Union Confederation ( ITUC ) , Just Transition is defined as a `` tool the trade union movement shares with the international community , aimed at smoothing the shift towards a more sustainable society and providing hope for the capacity of a green economy to sustain decent jobs and livelihoods for all '' ( ITUC , 2009b ) . It is important to note that Just Transition is a supporting mechanism of climate action , and not inaction . Just Transition is not in opposition to , but complements environmental policies . This comforts the idea that environmental and social policies are not contradictory but , on the contrary , can reinforce each other . This approach to the Just Transition concept was unanimously adopted at the 2nd ITUC Congress , in 2010 , when the Congress declared `` Just Transition '' to be `` the '' approach to fight climate change : 5 . Early mentions of Just Transition can also be found in ICFTU : ` Plough to Plate ' Approaches to Food and Agriculture , 2000 ; ICFTU : Fashioning A New Deal -- Workers and Trade Unions at the World Summit for Sustainable Development , 2002 . International Journal of Labour Research 2010 Vol . 2 Issue 2 142 Congress is committed to promoting an integrated approach to sustainable development through a just transition where social progress , environmental protection and economic needs are brought into a framework of democratic governance , where labour and other human rights are respected and gender equality achieved ( ITUC , 2010 ) . Other Global Union Federations , representing workers in specific economic sectors , joined this policy approach . The International Transport workers ' Federation ( ITF ) adopted , at its 2010 Congress , a resolution stating that `` while the urgent adoption of these policies is vital to tackle climate change , the ITF and its affiliates must defend the interests of transport workers by fighting to ensure that these policies are implemented in a way which protects jobs and creates new ones through a process of just transition '' ( ITF , 2010 ) . Federations of industrial workers have also voiced their positions on Just Transition . The International Federation of Chemical , Energy , Mine and General Workers ' Unions ( ICEM ) , for example , states that `` with a Just Transition , we can build a public consensus to move towards more sustainable production '' ( ICEM , 2009 ) . The Just Transition framework is a package of policy proposals which addresses the different aspects related to the vulnerability of workers and their communities : uncertainties regarding job impacts , risks of job losses , risks of undemocratic decision-making processes , risks of regional or local economic downturn , among others . A concept whose use has broadened In the past years , we have seen a number of organisations ( environmental and climate justice , foundations ) use the concept of Just Transition .

[ { "content": "Title: Timeline of the far future Content: While predictions of the future can never be absolutely certain , present understanding in various fields allows for the prediction of far-future events , if only in the broadest outline . These fields include astrophysics , which has revealed how planets and stars form , interact , and die ; particle physics , which has revealed how matter behaves at the smallest scales ; evolutionary biology , which predicts how life will evolve over time ; and plate tectonics , which shows how continents shift over millennia . All projections of the future of the Earth , the Solar System , and the Universe must account for the second law of thermodynamics , which states that entropy , or a loss of the energy available to do work , must increase over time . Stars will eventually exhaust their supply of hydrogen fuel and burn out . Close encounters gravitationally fling planets from their star systems , and star systems from galaxies . Eventually , matter itself is expected to come under the influence of radioactive decay , as even the most stable materials break apart into subatomic particles . Current data suggest that the universe has a flat geometry ( or very close to flat ) , and thus , will not collapse in on itself after a finite time , and the infinite future potentially allows for the occurrence of a number of massively improbable events , such as the formation of a Boltzmann brain . The timelines displayed here cover events from the beginning of the 11th millennium to the furthest reaches of future time . A number of alternate future events are listed to account for questions still unresolved , such as whether humans will become extinct , whether protons decay , or whether Earth will survive the Sun 's expansion into a red giant .", "qid": "565", "docid": "Timeline_of_the_far_future", "rank": 1, "score": 120206 }, { "content": "Title: Physics of the Future Content: Physics of the Future : How Science Will Shape Human Destiny and Our Daily Lives by the Year 2100 is a 2011 book by theoretical physicist Michio Kaku , author of Hyperspace and Physics of the Impossible .

Nonetheless , in modern days , nontheists have largely come to accept the theory , while Christian eschatology is in conflict with the idea that entropy will be the predominant factor in determining the state of the far future , instead predicting God 's creation of the New Earth and its existence into the far future . According to Mahayana Buddhism , an emanation of the Buddha-nature will appear in the material world in the far future .

These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end . These periods are caused by variations in eccentricity , axial tilt , and precession of the Earth 's orbit . As part of the ongoing supercontinent cycle , plate tectonics will probably result in a supercontinent in 250 -- 350 million years . Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present . This will cause the atmosphere to become a `` moist greenhouse '' , resulting in a runaway evaporation of the oceans . As a likely consequence , plate tectonics will come to an end , and with them the entire carbon cycle . Following this event , in about 2 − 3 billion years , the planet 's magnetic dynamo may cease , causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere . Four billion years from now , the increase in the Earth 's surface temperature will cause a runaway greenhouse effect , heating the surface enough to melt it . By that point , all life on the Earth will be extinct . The most probable fate of the planet is absorption by the Sun in about 7.5 billion years , after the star has entered the red giant phase and expanded to cross the planet 's current orbit .", "qid": "565", "docid": "Future_of_Earth", "rank": 7, "score": 109186 }, { "content": "Title: The Weather of the Future Content: The Weather of the Future : Heat Waves , Extreme Storms , and Other Scenes From a Climate-Changed Planet ( ISBN 978-0-06-172688-0 ) is a 2010 book by climatologist Heidi Cullen .

Von Collani 's answer is that the future outcome of any development does not exist at the beginning , since many different outcomes are possible , and that therefore it can not be predicted in principle . He concludes that the resulting uncertainty about the future outcome is the most striking feature of any real process and that this uncertainty leads to most of the problems humans are faced with .

Set in the 1950s , the narrator Ifan Powel takes part in a time travel experiment and lands in Cardiff in the year 2033 . He is hosted by a family and for 5 days is taken on a journey around Wales . He finds that Wales has secured self government and is prosperous economically , and socially harmonious ; everyone is bilingual in both Welsh and English . He falls in love with the daughter of his host family , Mair , and when he returns to the Wales of the 1950s his longing for her makes him want to return to 2033 . The scientist conducting the experiment cautions him against this as the future is not set and Ifan may therefore encounter a very different future if he travels again ( see Rules of Time Travel ) , but after Ifan begs for his help he agrees to send Ifan back . However , when Ifan returns he finds a totally different Wales . In this dystopian future , the Welsh language has died out and traces of Welsh identity have all but disappeared . Indeed , even the country 's name has been changed to `` Western England '' . Violence and social tensions are also commonplace . Ifan only stays here for two days in order to look for Mair , but when he finds her he discovers that her name in this future is Maria , and she has no memory of him . After returning to the present for the second time , the scientist explains to Ifan that both scenarios that Ifan encountered are possible for Wales and that it is up to the Welsh people which one comes to pass . This converts Ifan into a Welsh nationalist ( he had previously been opposed to nationalism ) and he swears to do everything within his power to ensure that the Wales that he visited first is the one that will be realised .

He can not speak and is said to give his answer by writing on paper . Initially , he is said to have shocked his parents by writing the names of all the countries in the world and the name of their leaders . He is also said to remember the name and occupation of everyone he meets , meaning of every words asked to him and even the meaning of the words from different language . Although many are shocked , credentials scientists are not amazed , many urge others to stay away from such beliefs . His predictions , although no one knows for a fact if those predictions were made by himself , are generally vague .

The basis of biodata 's predictive abilities is the axiom that past behaviour is the best predictor of future behaviour . Biographical information is not expected to predict all future behaviours but it is useful in personnel selection in that it can give an indication of probable future behaviours based on an individual 's prior learning history . Biodata instruments ( also called Biographical Information Blanks ) have an advantage over personality and interest inventories in that they can capture directly the past behaviour of a person , probably the best predictor of his or her future actions . These measures deal with facts about the person 's life , not introspections and subjective judgements . Over the years , personnel selection has relied on standardized psychological tests . The five major categories for these tests are intellectual abilities , spatial and mechanical abilities , perceptual accuracy , motor abilities and personality tests . The mean coefficient for a standardized test of g is 0.51 . A review of 58 studies on biodata found coefficients that ranged from 0.32 to 0.46 with a mean validity of 0.35 . The mean validity of interviews was found to be 0.19 . research has indicated a validity coefficient of 0.29 for unstructured interviews and 0.31 for structured interviews but interview results can be affected by interviewer biases and have been challenged in a number of different court cases .

Simply put , it says that supposing that all humans are born in a random order , chances are that any one human is born roughly in the middle . It was first proposed in an explicit way by the astrophysicist Brandon Carter in 1983 , from which it is sometimes called the Carter catastrophe ; the argument was subsequently championed by the philosopher John A. Leslie and has since been independently discovered by J. Richard Gott and Holger Bech Nielsen . Similar principles of eschatology were proposed earlier by Heinz von Foerster , among others . A more general form was given earlier in the Lindy effect , in which for certain phenomena the future life expectancy is proportional to ( though not necessarily equal to ) the current age , and is based on decreasing mortality rate over time : old things endure . Denoting by N the total number of humans who were ever or will ever be born , the Copernican principle suggests that humans are equally likely ( along with the other N − 1 humans ) to find themselves at any position n of the total population N , so humans assume that our fractional position f = n/N is uniformly distributed on the interval -LSB- 0 , 1 -RSB- prior to learning our absolute position . f is uniformly distributed on ( 0 , 1 ) even after learning of the absolute position n . That is , for example , there is a 95 % chance that f is in the interval ( 0.05 , 1 ) , that is f > 0.05 . In other words , we could assume that we could be 95 % certain that we would be within the last 95 % of all the humans ever to be born . If we know our absolute position n , this implies an upper bound for N obtained by rearranging n/N > 0.05 to give N < 20n . If Leslie 's figure is used , then 60 billion humans have been born so far , so it can be estimated that there is a 95 % chance that the total number of humans N will be less than 20 × 60 billion = 1.2 trillion . Assuming that the world population stabilizes at 10 billion and a life expectancy of 80 years , it can be estimated that the remaining 1140 billion humans will be born in 9120 years . Depending on the projection of world population in the forthcoming centuries , estimates may vary , but the main point of the argument is that it is unlikely that more than 1.2 trillion humans will ever live on Earth .

According to Ward , humanity may exist for a long time . Nevertheless , we are impacting our world . He splits his book in different chronologies , starting with the near future ( the next 1,000 years ) . Humanity would be struggling to support a massive population of 11 billion . Global warming raises sea levels . The ozone layer weakens . Most of the available land is devoted to agriculture due to the demand for food . Despite all this , the oceanic wildlife remains untethered by most of these impacts , specifically the commercial farmed fish . This is , according to Ward , an era of extinction that would last about 10 million years ( note that many human-caused extinctions have already occurred ) . After that , the world gets stranger . Ward labels the species that have the potential to survive in a human-infested world . These include dandelions , raccoons , owls , pigs , cattle , rats , snakes , and crows to name but a few . In the human-infested ecosystem , those preadapted to live amongst man survived and prospered . Ward describes garbage dumps in the future infested with multiple species of rats , a snake with a sticky frog-like tongue to snap up rodents , and pigs with snouts specialized for rooting through garbage . The story 's time traveller who views this new refuse-covered habitat is gruesomely attacked by ravenous flesh-eating crows . Ward then questions the potential for humanity to evolve into a new species . According to him , this is incredibly unlikely . For this to happen a human population must isolate itself and interbreed until it becomes a new species .

The term `` law '' has diverse usage in many cases : approximate , accurate , broad or narrow theories , in all natural scientific disciplines ( physics , chemistry , biology , geology , astronomy etc. ) . Scientific laws summarize and explain a large collection of facts determined by experiment , and are tested based on their ability to predict the results of future experiments . They are developed either from facts or through mathematics , and are strongly supported by empirical evidence . It is generally understood that they reflect causal relationships fundamental to reality , and are discovered rather than invented . Laws reflect scientific knowledge that experiments have repeatedly verified ( and never falsified ) . Their accuracy does not change when new theories are worked out , but rather the scope of application , since the equation ( if any ) representing the law does not change . As with other scientific knowledge , they do not have absolute certainty ( as mathematical theorems or identities do ) , and it is always possible for a law to be overturned by future observations . A law can usually be formulated as one or several statements or equations , so that it can be used to predict the outcome of an experiment , given the circumstances of the processes taking place . Laws differ from hypotheses and postulates , which are proposed during the scientific process before and during validation by experiment and observation . These are not laws since they have not been verified to the same degree and may not be sufficiently general , although they may lead to the formulation of laws . A law is a more solidified and formal statement , distilled from repeated experiment . Laws are narrower in scope than scientific theories , which may contain one or several laws . Unlike hypotheses , theories and laws may be simply referred to as scientific fact . Although the nature of a scientific law is a question in philosophy and although scientific laws describe nature mathematically , scientific laws are practical conclusions reached by the scientific method ; they are intended to be neither laden with ontological commitments nor statements of logical absolute #Noun .

This interdisciplinary field encompasses research on the origin and evolution of planetary systems , origins of organic compounds in space , rock-water-carbon interactions , abiogenesis on Earth , planetary habitability , research on biosignatures for life detection , and studies on the potential for life to adapt to challenges on Earth and in outer space . The chemistry of life may have begun shortly after the Big Bang , 13.8 billion years ago , during a habitable epoch when the Universe was only 10 -- 17 million years old . According to the panspermia hypothesis , microscopic life -- distributed by meteoroids , asteroids and other small Solar System bodies -- may exist throughout the universe . According to research published in August 2015 , very large galaxies may be more favorable to the creation and development of habitable planets than such smaller galaxies as the Milky Way . Nonetheless , Earth is the only place in the universe humans know to harbor life . Estimates of habitable zones around other stars , sometimes referred to as `` Goldilocks zones , '' along with the discovery of hundreds of extrasolar planets and new insights into extreme habitats here on Earth , suggest that there may be many more habitable places in the universe than considered possible until very recently . Current studies on the planet Mars by the Curiosity and Opportunity rovers are searching for evidence of ancient life as well as plains related to ancient rivers or lakes that may have been habitable . The search for evidence of habitability , taphonomy ( related to fossils ) , and organic molecules on the planet Mars is now a primary NASA and ESA objective .", "qid": "565", "docid": "Astrobiology", "rank": 95, "score": 75867 }, { "content": "Title: Ailuromancy Content: Ailuromancy or aeluromancy ( from Greek αἴλουρος aílouros meaning `` cat '' ) , also known as felidomancy , is a form of theriomancy .

Nearly all branches of natural science have contributed to the understanding of the main events of the Earth 's past . The age of Earth is approximately one-third of the age of the universe . An immense amount of geological change has occurred in that timespan , accompanied by the emergence of life and its subsequent evolution . Earth formed around 4.54 billion years ago by accretion from the solar nebula . Volcanic outgassing probably created the primordial atmosphere and then the ocean ; but the atmosphere contained almost no oxygen and so would have been toxic to most modern life including humans . Much of the Earth was molten because of frequent collisions with other bodies which led to extreme volcanism . A giant impact collision with a planet-sized body named Theia while Earth was in its earliest stage , also known as Early Earth , is thought to have been responsible for forming the Moon . Over time , the Earth cooled , causing the formation of a solid crust , and allowing liquid water to exist on the surface . The geological time scale ( GTS ) clock ( see graphic ) depicts the larger spans of time from the beginning of the Earth as well as a chronology of some definitive events of Earth history . The Hadean Eon represents time before the reliable ( fossil ) record of life beginning on Earth ; it began with the formation of the planet and ended at 4.0 billion years ago as defined by international convention . The Archean and Proterozoic eons follow ; they produced the abiogenesis of life on Earth and then the evolution of early life . The succeeding eon is the Phanerozoic , which is represented by its three component eras : the Palaeozoic ; the Mesozoic , which spanned the rise , reign , and climactic extinction of the huge dinosaurs ; and the Cenozoic , which presented the subsequent development of dominant mammals on Earth . Hominins , the earliest direct ancestors of the human clade , rose sometime during the latter part of the Miocene epoch ; the precise time marking the first hominins is broadly debated over a current range of 13 to 4 mya . The succeeding Quaternary period is the time of recognizable humans , i.e. , the genus Homo , but that period 's two million-year-plus term of the recent times is too small to be visible at the scale of the GTS graphic . ( Notes re the graphic : Ga means `` billion years '' ; Ma , `` million years '' . ) The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago , during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon . There are microbial mat fossils such as stromatolites found in 3.48 billion-year-old sandstone discovered in Western Australia . Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old metasedimentary rocks discovered in southwestern Greenland as well as `` remains of biotic life '' found in 4.1 billion-year-old rocks in Western Australia . According to one of the researchers , `` If life arose relatively quickly on Earth ... then it could be common in the universe . '' Living forms derived from photosynthesis appeared between 3.2 and 2.4 billion years ago and began enriching the atmosphere with oxygen . Life remained mostly small and microscopic until about 580 million years ago , when complex multicellular life arose , developed over time , and culminated in the Cambrian Explosion about 541 million years ago . This event drove a rapid diversification of life forms on Earth that produced most of the major phyla known today ; and it marked the end of the Proterozoic Eon and the beginning of the Cambrian Period of the Paleozoic Era . More than 99 percent of all species , amounting to over five billion species , that ever lived on Earth are estimated to be extinct . Estimates on the number of Earth 's current species range from 10 million to 14 million , of which about 1.2 million have been documented and over 86 percent have not yet been described . More recently , in May 2016 , scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described . Geological change has been a constant of Earth 's crust since the time of its formation , and biological change since the first appearance of life . Species continue to evolve , taking on new forms , splitting into daughter species or going extinct in the process of adapting or dying in response to ever-changing physical environments . The process of plate tectonics continues to play a dominant role in the shaping of Earth 's oceans and continents and the living species they harbor . Changes in the biosphere -- now dominated by human activity -- continue , in turn , to produce significant effects on the atmosphere and other systems of the Earth 's surface , such as the integrity of the ozone layer , the proliferation of greenhouse gases , the conditions of productive soils and clean air and water , and others .", "qid": "565", "docid": "History_of_Earth", "rank": 100, "score": 75678 } ]

Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction . Climate changes is projected to affect individual organisms , populations , species distributions and ecosystem composition and function both directly ( ex . Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) . Every organism has a unique set of preferences or requirements , a niche and biodiversity has been tied to the diversity of animals ' niches . These can include or be affected by temperature , aridity , resource availability , habitat requirements , enemies , soil characteristics , competitors , and pollinators .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering .

In the late 19th century , scientists first argued that human emissions of greenhouse gases could change the climate . Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change . Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years . It may be a change in average weather conditions , or in the distribution of weather around the average conditions ( such as more or fewer extreme weather events ) . Climate change is caused by factors that include oceanic processes ( such as oceanic circulation ) , biotic processes , variations in solar radiation received by Earth , plate tectonics and volcanic eruptions , and human-induced alterations of the natural world .

In 2013 , the CSIRO released a report stating that Australia is becoming hotter , and that it will experience more extreme heat and longer fire seasons because of climate change . In 2014 , the Bureau of Meteorology released a report on the state of Australia 's climate that highlighted several key points , including the significant increase in Australia 's temperatures ( particularly night-time temperatures ) and the increasing frequency of bush fires , droughts and floods , which have all been linked to climate change . Since the beginning of the 20th century Australia has experienced an increase of nearly 1 ° C in average annual temperatures , with warming occurring at twice the rate over the past 50 years than in the previous 50 years . Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the impacts of climate change in Australia . Rainfall in southwestern Australia has decreased by 10 -- 20 % since the 1970s , while southeastern Australia has also experienced a moderate decline since the 1990s . Rainfall patterns are expected to be problematic , as rain has become heavier and infrequent , as well as more common in summer rather than in winter , with little or no uptrend in rainfall in the Western Plateau and the Central Lowlands of Australia . Water sources in the southeastern areas of Australia have depleted due to increasing population in urban areas ( rising demand ) coupled with climate change factors such as persistent prolonged drought ( diminishing supply ) . At the same time , Australia continues to have the highest per capita greenhouse gas emissions . Temperatures in Australia have also risen dramatically since 1910 and nights have become warmer . A carbon tax was introduced in 2011 by the Gillard government in an effort to reduce the impact of climate change and despite some criticism , it successfully reduced Australia 's carbon dioxide emissions , with coal generation down 11 % since 2008 -- 09 . The subsequent Australian Government , elected in 2013 under then Prime Minister Tony Abbott was criticised for being `` in complete denial about climate change '' . Furthermore , the Abbott government repealed the carbon tax on 17 July 2014 in a heavily criticised move . The renewable energy target ( RET ) , launched in 2001 , was heavily modified under Abbott 's government . However , under the government of Malcolm Turnbull , Australia attended the 2015 United Nations Climate Change Conference and adopted the Paris Agreement . This agreement includes a review of emission reduction targets every 5 years from 2020 . The federal government and all state governments ( New South Wales , Victoria , Queensland , South Australia , Western Australia , Tasmania , Northern Territory and the Australian Capital Territory ) have explicitly recognised that climate change is being caused by greenhouse gas emissions , in conformity with the scientific opinion on climate change . Sectors of the population have campaigned against new coal mines and coal-fired power stations , reflecting concerns about the effects of global warming on Australia . The Garnaut Climate Change Review predicted that a net benefit to Australia may be derived by stabilising greenhouse gases in the atmosphere at 450ppm CO2 eq . The per-capita carbon footprint in Australia was rated 12th in the world by PNAS in 2011 , considerably large given the small population of the country .", "qid": "567", "docid": "Climate_change_in_Australia", "rank": 44, "score": 71714 }, { "content": "Title: Climate change in Tuvalu Content: Global warming (recent climate change) is particularly threatening in Tuvalu.

Between 1971 and 2014, during a period of global warming, Tuvalu islands have increased in size, according to aerial photography and satellite imagery. Over four decades, there was a net increase in land area in Tuvalu of 73.5 ha (2.9%), although the changes were not uniform, with 74% of land increasing in size and 27% of land decreasing in size. The sea level at the Funafuti tide gauge has risen at 3.9 mm per year, which is approximately twice the global average.Tuvalu could be one of the first nations to be significantly impacted by rising sea levels. Not only could parts of the island be flooded but the rising saltwater table could also destroy deep rooted food crops such as coconut, pulaka, and taro. Research from the University of Auckland suggests that Tuvalu may remain habitable over the next century. However, as of March 2018, Prime Minister Enele Sopoaga stated that Tuvalu is not expanding and has gained no additional habitable land.

The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 .

In the current episode of global warming many such 15-year periods appear in the surface temperature record , along with robust evidence of the long-term warming trend ; climate is classically averaged over 30-year periods . Publicity has surrounded claims of a global warming hiatus during the period 1998 -- 2013 . The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend , and so subsequent annual temperatures gave the appearance of a hiatus : by January 2006 , it appeared to some that global warming had stopped or paused . A 2009 study showed that decades without warming were not exceptional , and in 2011 a study showed that if allowances were made for known variability , the rising temperature trend continued unabated . There was increased public interest in 2013 in the run-up to publication of the IPCC Fifth Assessment Report , and despite concerns that a 15-year period was too short to determine a meaningful trend , the IPCC included a section on a hiatus , which it defined as a much smaller increasing linear trend over the 15 years from 1998 to 2012 , than over the 60 years from 1951 to 2012 . Various studies examined possible causes of the short-term slowdown . Even though the overall climate system has continued to accumulate energy due to Earth 's positive energy budget , the available temperature readings at the Earth 's surface indicate slower rates of increase in surface warming than in the prior decade . Since measurements at the top of the atmosphere show that Earth is receiving more energy than it is radiating back into space , the retained energy should be producing warming in the Earth 's climate system . Research reported in July 2015 on an updated NOAA dataset casts doubt on the existence of a hiatus , and it finds no indication of a slowdown even in earlier years . Scientists working on other datasets welcomed this study , though they have expressed the view that the recent warming trend was less than in previous periods of the same length . Subsequently , a detailed study supports the conclusion that warming is continuing , but it also find there was less warming between 2001 and 2010 than climate models had predicted , and that this slowdown might be attributed to short-term variations in the Pacific decadal oscillation ( PDO ) , which was negative during that period . Another review finds `` no substantive evidence '' of a pause in global warming . A statistical study of global temperature data since 1970 concludes that the term ` hiatus ' or ` pause ' is not justified . Independent of these discussions about data and measurements for earlier years , 2015 turned out to be much warmer than any of the earlier years , already before El Niño conditions started . The warmth of 2015 largely ended any remaining scientific credibility of claims that the supposed `` hiatus '' since 1998 had any significance for the long-term warming trend . In January 2017 , a study published in the journal Science Advances cast further doubt on the existence of a recent pause , with more evidence that ocean temperatures have been underestimated . An April 2017 study found the data consistent with a steady warming trend globally since the 1970s , with fluctuations within the expected range of short term variability .", "qid": "567", "docid": "Global_warming_hiatus", "rank": 78, "score": 68822 }, { "content": "Title: 4Change Content: 4Change , formerly known as the Climate Change Coalition ( CCC ) , was an Australian political party , which was formed in 2007 with a view to accelerate action by politicians from all parties on global warming and climate change .

Climate change mitigation generally involves reductions in human ( anthropogenic ) emissions of greenhouse gases ( GHGs ) . Mitigation may also be achieved by increasing the capacity of carbon sinks , e.g. , through reforestation . Mitigation policies can substantially reduce the risks associated with human-induced global warming . According to the IPCC 's 2014 assessment report , `` Mitigation is a public good ; climate change is a case of the ` tragedy of the commons . Effective climate change mitigation will not be achieved if each agent ( individual , institution or country ) acts independently in its own selfish interest ( see international cooperation and emissions trading ) , suggesting the need for collective action . Some adaptation actions , on the other hand , have characteristics of a private good as benefits of actions may accrue more directly to the individuals , regions , or countries that undertake them , at least in the short term . Nevertheless , financing such adaptive activities remains an issue , particularly for poor individuals and countries . '' Examples of mitigation include phasing out fossil fuels by switching to low-carbon energy sources , such as renewable and nuclear energy , and expanding forests and other `` sinks '' to remove greater amounts of carbon dioxide from the atmosphere . Energy efficiency may also play a role , for example , through improving the insulation of buildings . Another approach to climate change mitigation is climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) . The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of GHGs at a level that would prevent dangerous human interference of the climate system . Scientific analysis can provide information on the impacts of climate change , but deciding which impacts are dangerous requires value judgments . In 2010 , Parties to the UNFCCC agreed that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . With the Paris Agreement of 2015 this was confirmed , but was revised with a new target laying down `` parties will do the best '' to achieve warming below 1.5 ° C . The current trajectory of global greenhouse gas emissions does not appear to be consistent with limiting global warming to below 1.5 or 2 ° C .

Most of the key REDD + decisions were completed by 2013 , with the final pieces of the rulebook finished in 2015 . In the last two decades , various studies estimate that land use change , including deforestation and forest degradation , accounts for 12-29 % of global greenhouse gas emissions . For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) . What remained on forestry was `` Afforestation and Reforestation '' , sectoral scope 14 of the CDM . Under this sectoral scope areas of land that had no forest cover since 1990 could be replanted with commercial or indigenous tree species . In its first eight years of operation 52 projects had been registered under the `` Afforestation and Reforestation '' scope of the CDM . The cumbersome administrative procedures and corresponding high transaction costs are often blamed for this slow uptake . Beyond the CDM , all developed countries that were parties to the Kyoto Protocol also committed to measuring and reporting on efforts to reduce net greenhouse gas emissions from forests . The United States also measures and reports on the net greenhouse gas sequestration in its forests . In response to what many perceived to be a failure to address a major source of global greenhouse gas emissions , the Coalition for Rainforest Nations ( CfRN ) was established and in 2005 they proposed to the Conference of the Parties to the UNFCCC policy approaches and positive incentives for the reduction of emissions of greenhouse gases stemming from tropical deforestation and forest degradation as a climate change mitigation measure .", "qid": "567", "docid": "Reducing_emissions_from_deforestation_and_forest_degradation", "rank": 86, "score": 68325 }, { "content": "Title: Effects of climate change on plant biodiversity Content: Environmental conditions play a key role in defining the function and distribution of plants , in combination with other factors .

The UNFCCC objective is to `` stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system '' . The framework sets no binding limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms . Instead , the framework outlines how specific international treaties ( called `` protocols '' or `` Agreements '' ) may be negotiated to specify further action towards the objective of the UNFCCC . Initially an Intergovernmental Negotiating Committee ( INC ) produced the text of the Framework Convention during its meeting in New York from 30 April to 9 May 1992 . The UNFCCC was adopted on 9 May 1992 , and opened for signature on 4 June 1992 . The UNFCCC has 197 parties as of December 2015 . The convention enjoys broad legitimacy , largely due to its nearly universal membership . The parties to the convention have met annually from 1995 in Conferences of the Parties ( COP ) to assess progress in dealing with climate change . In 1997 , the Kyoto Protocol was concluded and established legally binding obligations for developed countries to reduce their greenhouse gas emissions in the period 2008-2012 . The 2010 Cancún agreements state that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . The Protocol was amended in 2012 to encompass the period 2013-2020 in the Doha Amendment , which - as of December 2015 - had not entered into force . In 2015 the Paris Agreement was adopted , governing emission reductions from 2020 on through commitments of countries in ambitious Nationally Determined Contributions . The Paris Agreement entered into force on November 4th , 2016 . One of the first tasks set by the UNFCCC was for signatory nations to establish national greenhouse gas inventories of greenhouse gas ( GHG ) emissions and removals , which were used to create the 1990 benchmark levels for accession of Annex I countries to the Kyoto Protocol and for the commitment of those countries to GHG reductions . Updated inventories must be submitted annually by Annex I countries .

Some deniers do endorse the term , but others often prefer the term climate change skepticism , although this is a misnomer for those who deny anthropogenic global warming . In effect , the two terms form a continuous , overlapping range of views , and generally have the same characteristics : both reject , to a greater or lesser extent , mainstream scientific opinion on climate change . Climate change denial can also be implicit , when individuals or social groups accept the science but fail to come to terms with it or to translate their acceptance into action . Several social science studies have analyzed these positions as forms of denialism . Campaigning to undermine public trust in climate science has been described as a `` denial machine '' of industrial , political and ideological interests , supported by conservative media and skeptical bloggers in manufacturing uncertainty about global warming . In the public debate , phrases such as climate skepticism have frequently been used with the same meaning as climate denialism . The labels are contested : those actively challenging climate science commonly describe themselves as `` skeptics '' , but many do not comply with common standards of scientific skepticism and , regardless of evidence , persistently deny the validity of human caused global warming . Although scientific opinion on climate change is that human activity is extremely likely to be the primary driver of climate change , the politics of global warming have been affected by climate change denial , hindering efforts to prevent climate change and adapt to the warming climate . Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none . Of the world 's countries , the climate change denial industry is most powerful in the United States . Since January 2015 , the United States Senate Committee on Environment and Public Works has been chaired by oil lobbyist and climate change denier Jim Inhofe . Inhofe is notorious for having called climate change `` the greatest hoax ever perpetrated against the American people '' and for having claimed to have debunked the alleged hoax in February 2015 when he brought a snowball with him in the Senate chamber and tossed it across the floor . Organised campaigning to undermine public trust in climate science is associated with conservative economic policies and backed by industrial interests opposed to the regulation of emissions . Climate change denial has been associated with the fossil fuels lobby , the Koch brothers , industry advocates and libertarian think tanks , often in the United States .

Many ecosystems , particularly prairie , savanna , chaparral and coniferous forests , have evolved with fire as an essential contributor to habitat vitality and renewal . Many plant species in fire-affected environments require fire to germinate , establish , or to reproduce . Wildfire suppression not only eliminates these species , but also the animals that depend upon them . Campaigns in the United States have historically molded public opinion to believe that wildfires are always harmful to nature . This view is based on the outdated belief that ecosystems progress toward an equilibrium and that any disturbance , such as fire , disrupts the harmony of nature . More recent ecological research has shown , however , that fire is an integral component in the function and biodiversity of many natural habitats , and that the organisms within these communities have adapted to withstand , and even to exploit , natural wildfire . More generally , fire is now regarded as a ` natural disturbance ' , similar to flooding , wind-storms , and landslides , that has driven the evolution of species and controls the characteristics of ecosystems .

Some large wildfires in the United States have been blamed on years of fire suppression and the continuing expansion of people into fire-adapted ecosystems , but climate change is more likely responsible .

The best known example of this is the Carboniferous Rainforest Collapse which occurred 350 million years ago . This event decimated amphibian populations and spurred on the evolution of reptiles . Climate change is a natural event that has occurred throughout history . However , with the recent increased emission of CO2 in the Earth 's atmosphere , abrupt climate change has occurred . It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about 8000 before present ( Van Hoof 2006 ) . Animals have had specific responses to climate change . Species respond to climate changes by migration , adaptation , or if neither of those occur , death . These migrations can sometimes follow an animal 's preferred temperature , elevation , soil , etc. , as said terrain moves due to climate change . Adaptation can be either genetic or phenological , and death can occur in a local population only ( extirpation ) or as an entire species , otherwise known as extinction . Climate changes is projected to affect individual organisms , populations , species distributions and ecosystem composition and function both directly ( ex . Increased temperatures and changes in precipitation ) and indirectly ( through climate changing the intensity and frequency of disturbances such as wildfires and severe storms ) ( IPCC 2002 ) . Every organism has a unique set of preferences or requirements , a niche and biodiversity has been tied to the diversity of animals ' niches . These can include or be affected by temperature , aridity , resource availability , habitat requirements , enemies , soil characteristics , competitors , and pollinators .

As the ice forms from the incremental buildup of annual layers of snow , lower layers are older than upper , and an ice core contains ice formed over a range of years . The properties of the ice and the recrystallized inclusions within the ice can then be used to reconstruct a climatic record over the age range of the core , normally through isotopic analysis . This enables the reconstruction of local temperature records and the history of atmospheric composition . Ice cores contain an abundance of information about climate . Inclusions in the snow of each year remain in the ice , such as wind-blown dust , ash , pollen , bubbles of atmospheric gas and radioactive substances . The variety of climatic proxies is greater than in any other natural recorder of climate , such as tree rings or sediment layers . These include ( proxies for ) temperature , ocean volume , precipitation , chemistry and gas composition of the lower atmosphere , volcanic eruptions , solar variability , sea-surface productivity , desert extent and forest fires . The length of the record depends on the depth of the ice core and varies from a few years up to 800 kyr ( 800,000 years ) for the EPICA core . The time resolution ( i.e. the shortest time period which can be accurately distinguished ) depends on the amount of annual snowfall , and reduces with depth as the ice compacts under the weight of layers accumulating on top of it . Upper layers of ice in a core correspond to a single year or sometimes a single season . Deeper into the ice the layers thin and annual layers become indistinguishable . An ice core from the right site can be used to reconstruct an uninterrupted and detailed climate record extending over hundreds of thousands of years , providing information on a wide variety of aspects of climate at each point in time .

During a pole 's winter , it lies in continuous darkness , chilling the surface and causing the deposition of 25 -- 30 % of the atmosphere into slabs of CO2 ice ( dry ice ) . When the poles are again exposed to sunlight , the frozen CO2 sublimes , creating enormous winds that sweep off the poles as fast as 400 km/h . These seasonal actions transport large amounts of dust and water vapor , giving rise to Earth-like frost and large cirrus clouds . Clouds of water-ice were photographed by the Opportunity rover in 2004 . The caps at both poles consist primarily of water ice . Frozen carbon dioxide accumulates as a comparatively thin layer about one metre thick on the north cap in the northern winter only , while the south cap has a permanent dry ice cover about 8 m thick . The northern polar cap has a diameter of about 1000 km during the northern Mars summer , and contains about 1.6 million cubic km of ice , which if spread evenly on the cap would be 2 km thick .

Both polar caps show spiral troughs , which recent analysis of SHARAD ice penetrating radar has shown are a result of roughly perpendicular katabatic winds that spiral due to the Coriolis Effect . The seasonal frosting of some areas near the southern ice cap results in the formation of transparent 1 m thick slabs of dry ice above the ground .

Many rare and usual herbaceous plants are found here , particularly orchids ( e.g. Calopogon species , Pogonia ophioglossoides ) , sedges ( e.g. Rhynchospora species ) and carnivorous plants ( e.g. Sarracenia species ) . A second key factor is moisture . Overall , wet pine savannas have more species than pine savannas , and the distribution of each species within a savanna is intimately connected with soil moisture regimes . Temporary ponds , and seepage areas , are therefore a critical control on plant species composition . Orchids and pitcher plants , for example , are associated with wetter locations . But even these wetter locations burn during dry periods , allowing regeneration of species of pitcher plant and sundew . Pineywoods are characterized by low basal area and large widely spaced mature pine . Historically , the flatwoods were dominated by longleaf pine , which can live to be 500 years old . Large scale overharvesting in conjunction with detrimental silvicultural practices like replacement with faster growing loblolly pine has drastically reduced the range of the longleaf pine ecosystem . Longleaf requires frequent fires , ideally every 1 -- 3 years , which prevent invasion of the habitat by other tree species . Decades of fire exclusion in the Southeast have contributed to the decline of this community type . However , with the restoration of fire , and natural flooding regimes , it is possible to restore small areas of habitat , and with concerted effort , several large wilderness areas could still be restored east of the Mississippi River . Some of the largest remaining areas of this habitat type are found in De Soto National Forest , Eglin Air Force Base , and Apalachicola National Forest .", "qid": "568", "docid": "Flatwoods", "rank": 23, "score": 120915 }, { "content": "Title: Ferrallitisation Content: Ferrallitisation is the process in which rock is changed into a soil consisting of clay ( kaolinite ) and sesquioxides , in the form of hydrated oxides of iron and aluminium .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions . They were preserved so well by quick freezing , which is taken as evidence of a rapid onset of a global blizzard or similar event . Interspersed with the analytical parts of the book are a series of interlinked short fictional scenarios , written in italics , describing what might transpire today if a destabilization of the North Atlantic Current were to occur .

The covering of much of the Sahara desert by grasses, trees and lakes was caused by changes in Earth's orbit around the Sun; changes in vegetation and dust in the Sahara which strengthened the African monsoon; and increased greenhouse gases, which may imply that anthropogenic global warming could result in a shrinkage of the Sahara desert. During the preceding last glacial maximum, the Sahara contained extensive dune fields and was mostly uninhabited. It was much larger than today, but its lakes and rivers such as Lake Victoria and the White Nile were either dry or at low levels. The humid period began about 14,600–14,500 years ago at the end of Heinrich event 1, simultaneously to the Bølling-Allerød warming. Rivers and lakes such as Lake Chad formed or expanded, glaciers grew on Mount Kilimanjaro and the Sahara retreated. Two major dry fluctuations occurred; during the Younger Dryas and the short 8.2 kiloyear event. The African humid period ended 6,000–5,000 years ago during the Piora Oscillation cold period.

Following John T. Hollin 's work ( 1962 ) suggesting that climatic warming and rising sea-level cause Antarctic ice shelves to retreat , Mercer postulated that the West Antarctic ice sheet , being grounded well below sea-level and terminating in floating ice shelves , was vulnerable to these changes and may have collapsed altogether during the last interglacial when Antarctica may have been warmer and sea-level may have been higher . In 1978 , in the science magazine Nature , Mercer pointed out that `` green-house '' warming from burning fossil fuel could have the same effect during the present interglacial . Two studies published 12 May 2014 confirm Mercer 's assumption . Climate scientist James Hansen has coined the term , `` John Mercer effect . '' After Mercer published his paper suggesting that the West Antarctic ice sheet could collapse in response to warming , he struggled to get funding . Others , including Hansen , had similar problems . Many climate scientists censor their own work to avoid losing funding , especially regarding prospects for limiting warming to 2 ° C above pre-industrial temperatures . John H. Mercer was the third child of Harriet and John W. Mercer . He was educated at private schools in Cheltenham and , later , at Gordonstoun in Scotland .

Much of the land in this area would be seabed if the ice sheet were not there . In contrast to the melting of the Arctic sea ice , sea ice around Antarctica was expanding . The reasons for this are not fully understood , but suggestions include the climatic effects on ocean and atmospheric circulation of the ozone hole , and/or cooler ocean surface temperatures as the warming deep waters melt the ice shelves .", "qid": "568", "docid": "Antarctic_ice_sheet", "rank": 50, "score": 109285 }, { "content": "Title: Plant ecology Content: Plant ecology is a subdiscipline of ecology which studies the distribution and abundance of plants , the effects of environmental factors upon the abundance of plants , and the interactions among and between plants and other organisms . Examples of these are the distribution of temperate deciduous forests in North America , the effects of drought or flooding upon plant survival , and competition among desert plants for water , or effects of herds of grazing animals upon the composition of grasslands . A global overview of the Earth 's major vegetation types is provided by O.W. Archibold . He recognizes 11 major vegetation types : tropical forests , tropical savannas , arid regions ( deserts ) , Mediterranean ecosystems , temperate forest ecosystems , temperate grasslands , coniferous forests , tundra ( both polar and high mountain ) , terrestrial wetlands , freshwater ecosystems and coastal/marine systems . This breadth of topics shows the complexity of plant ecology , since it includes plants from floating single-celled algae up to large canopy forming trees . One feature that defines plants is photosynthesis . One of the most important aspects of plant ecology is the role plants have played in creating the oxygenated atmosphere of earth , an event that occurred some 2 billion years ago . It can be dated by the deposition of banded iron formations , distinctive sedimentary rocks with large amounts of iron oxide . At the same time , plants began removing carbon dioxide from the atmosphere , thereby initiating the process of controlling Earth 's climate . A long term trend of the Earth has been toward increasing oxygen and decreasing carbon dioxide , and many other events in the Earths history , like the first movement of life onto land , are likely tied to this sequence of events . One of the early classic books on plant ecology was written by J.E. Weaver and F.E. Clements . It talks broadly about plant communities , and particularly the importance of forces like competition and processes like succession . Although some of the terminology is dated , this important book can still often be obtained in used book stores . Plant ecology can also be divided by levels of organization including plant ecophysiology , plant population ecology , community ecology , ecosystem ecology , landscape ecology and biosphere ecology . The study of plants and vegetation is complicated by their form . First , most plants are rooted in the soil , which makes it difficult to observe and measure nutrient uptake and species interactions . Second , plants often reproduce vegetatively , that is asexually , in a way that makes it difficult to distinguish individual plants . Indeed , the very concept of an individual is doubtful , since even a tree may be regarded as a large collection of linked meristems . Hence , plant ecology and animal ecology have different styles of approach to problems that involve processes like reproduction , dispersal and mutualism . Some plant ecologists have placed considerable emphasis upon trying to treat plant populations as if they were animal populations , focusing on population ecology . Many other ecologists believe that while it is useful to draw upon population ecology to solve certain scientific problems , plants demand that ecologists work with multiple perspectives , appropriate to the problem , the scale and the situation .", "qid": "568", "docid": "Plant_ecology", "rank": 51, "score": 109212 }, { "content": "Title: Tropical ecology Content: Tropical ecology is the study of the relationships between the biotic and abiotic components of the tropics , or the area of the Earth that lies between the Tropic of Cancer and the Tropic of Capricorn ( 23.4378 ° N and 23.4378 ° S , respectively ) .

Temperature is the primary determinate for spatial patterns of fir and spruce . The two dominant trees in this type of forest are Picea engelmannii ( Engelmann spruce ) and Abies lasiocarpa ( subalpine fir ) . Although thick-barked trees , such as the Pinus resinosa , frequently survive fire , the thin bark of spruce make them more vulnerable . Trees such as the Douglas fir withstand much of the fire due to the thicker bark they have . The scale of the burn mosaic during a fire , relative to species niche requirements and mobility , can have major impacts on flora and fauna dynamics . Forests of the Southern Appalachian Mountains had covered approximately 140 km ² on peaks and ranges . Today this forest type occupies less than 70 km ² . Much of this forest loss is due to logging , followed by slash fires . The Waterrock Knob fire was composed of different group of plant species than are normally found in burned spruce and fir forests . The tree layer of this stand consists of fewer than expected stems and has low basal area . The shrub layer is very dense , which may reduce successful tree reproduction . The herbaceous layer growth is not typical of young , disturbed spruce and fir stands . These vegetation characteristics suggest that possibly a hot fire in conjunction with a steep rocky slope and shallow soils have been some of the reasons for the reduced development of a typical spruce and fir stand . Burned soil has been an important factor in determining earlier and present vegetation patterns and species composition . Post fire effects of the western United States forests include an important study of the fire of Yellowstone National Park in 1988 . Historically , controlled burns had been utilized to thin forests . By the 1970s , Yellowstone started a natural fire management plan to allow the process of lightning caused fires to continue influencing wild land succession . In 1988 , 248 fires were started in Yellowstone National Park . As for the animals that were killed by the fires , the U.S National Park Service tallied 345 elk , 36 deer , 12 moose , 6 black bears , 9 bison and 1 grizzly bear . Fish were also killed due to heated water . Surveys indicated that less than 1 % of the soils were heated enough to burn below ground plant seeds and roots . The U.S Congress launched a massive study of the long term ecological effects caused by the Yellowstone fires . The short term effects proved most wildlife populations showed no effects or rebounded quickly . In the years following the fire , precipitation combined with short term ash and nutrient influx led to a stunning display of wild flowers on the burned areas . Because plants are immobile , they must develop resistances to disturbances through natural selection . Individual plant species vary their resistance to fire injury in predictable ways . These resistances make it possible for the biodiversity to greatly increase during recolonization after a fire . Studies show that in a spruce and fir forest , eleven years after a fire , there is a greater diversity of herbs than in a community where there was no fire . The shrubs took longer to regenerate but soon there was greater diversity in the shrub population as well . Spruce and fir forests have a greater biodiversity than most other forests because of their multiple layers of canopy and dense understories . This creates a heterogeneous , diverse stand structure which leads to an assortment of fire types which usually leave patches of unburned trees . Because the soil is oxidized by the fire , seed germination is encouraged . Also , many herb species were present in burned areas but not areas that were unaffected by fire . Fir and spruce trees are wind-dispersed , so the number of regenerated trees depends on the distance from the unburned stands to the sample location . The time it takes for fir and spruce to regenerate varies greatly , but it takes a number of years if no roots or snags remain . Regeneration time depends on a number of environmental factors , such as species type , wind strength , and aspect . It may be much more difficult for fir and spruce to be established on a slope , not only because of the dispersion technique , but also because erosion is greatly increased by fire , making it harder for the seeds to take root . Also , fir and spruce differ in survival techniques . Fir uses rapid growth , short lifespan , and easy establishment to come back more quickly after a fire , while spruce relies on longer lifespan and larger basal area to survive . Spruce has a much lower establishment rate , but the larger basal area increases its chances of survival and allows it to regenerate by both wind dispersion and growth from the roots remaining after a fire . The result is that fir and spruce repopulate the site contemporaneously , although most of the initial biomass is dominated by fir and later on the dominance shifts to spruce . Recurrent high-intensity crown fire also helps spruce and fir forests by preventing fir from overtaking spruce through competitive exclusion . Because spruce is shade-intolerant , it requires an open canopy to be established . This means that without fire to wipe out fir trees , thus creating holes in the canopy , spruce would be outcompeted by fir . Fire has an interesting relationship with micro fauna in forests . Damage done to trees by fire hurts the vascular cambium , thus leaving trees more susceptible to insectivorous and fungal attacks . Fungal infections are not as common as insect attacks , but can be just as deadly . The fungus Amylostereum areolatum weakens trees and allows insects such as the Sirex noctilio ( European wood wasp ) to take over massive numbers of forests . The most common problems in spruce and fir forests are bark beetles , budworms , and gall-forming insects , to which spruce is extremely susceptible . Several gall-forming insects are present in spruce forests , including the Eastern Spruce gall adelgid and the Cooley 's Spruce gall adelgid , which normally would not harm forests , unless the trees are unusually vulnerable to them , as they are after a fire . Budworm larvae feed on the leaves of spruce and fir trees , and can become present in large amounts , which is when they become detrimental to a forest . Bark beetles are the most common insect killer of spruce and fir forests because they can spread quickly , breed rapidly , and can easily devour thousands of acres before actions can be taken against them . During the 1990s , the bark beetles affected almost three million acres ( 12,000 km ² ) of spruce forests . The attacks of these insects , in turn , raise the mortality rate of trees in the burn area , which provides even more fuel for the next fire . A number of larger animals are supported by fir and spruce forests , such as moose , deer , elk , birds , snowshoe hares , and other small mammals . Effects on bird populations after fire in fir and spruce forests varied . Of the 41 avian species observed in 3 or more studies comparing post fire and adjacent unburned forests , 22 % are consistently more abundant in burned forests and 34 % are more abundant in unburned forests . In general , woodpeckers and aerial foragers are more abundant in burned forests and foliage grazing species are more abundant in unburned forests . Within the spruce and fir community type , trees often lose their lower branches , becoming unavailable to hare and other small mammals for food or cover during the seven to nine months of winter . This makes larger mammals more densely populated in fir and spruce forests . Fire does not displace fauna that are dependent on fir and spruce forests . When fir and spruce begin sprouting , they are utilized for food and the patches of trees remaining provides shelter . Because of the heterogeneity in fir and spruce forests , patches of trees are always left in nature . Fire suppression , on the other hand , alters the natural patch dynamics , thus greatly reducing the number of mammals present . The trees all grow older , close the canopy , the understory is repressed , branches fall off during the winter , and for the majority of the year there is no available food . Also , if fire is suppressed for a number of years and then a crown fire breaks out in the area , it will quickly spread throughout the dense canopy . No patches will be left for shelter and the fir and spruce will take much longer to regenerate because of the distance from the remaining stands to the center of the burned site .", "qid": "568", "docid": "Spruce-fir_forests", "rank": 66, "score": 105824 }, { "content": "Title: Trianthema portulacastrum Content: Trianthema portulacastrum is a species of flowering plant in the ice plant family known by the common names desert horsepurslane , black pigweed , and giant pigweed .

Tropical peatlands are vulnerable to destabilisation through human and climate induced changes . Estimates of the area ( and hence volume ) of tropical peatland vary but a reasonable estimate is in the region of 380,000 square kilometres .

Disruption due to climate change , or other anthropogenic perturbations can result in decreased productivity and in some cases lead to disruptions in global biogeochemical cycles . The possible ramifications of changes in ecosystem biodiversity are not well characterized or understood , and it may be possible that disruption , up to a point , will have little to no effect given the redundancy within an ecosystem . This is particularly troubling in the context of microbial ecosystems . The dynamics of microbial ecosystems are tightly coupled to biogeochemical processes , and any perturbation within this system in particular could result in dramatic changes ( Kirchman , 2008 ) . For example , the microbial loop within the marine context is responsible for the decomposition of organics and recycling of nutrients back into the ecosystem . This allows for other organisms , such as phytoplankton , to reuse essential nutrients , like nitrogen , and continue production ( Kirchman 2008 ) . Without this recycled nitrogen , phytoplankton would be highly limited in their production rates , in turn limiting the growth of grazers . The effects of such an occurrence would reverberate throughout the food web , and nitrogen cycle . It is important to establish a base line of microbial diversity within ecosystems in order to gauge possible change due to climate change and the possible outcomes . Recent use of high-throughput sequencing techniques has broadened the scope of biodiversity , with the discovery of what has been titled the `` Rare Biosphere '' ( Sogin et al. , 2006 ) . Previous attempts to characterize in situ abundance have been made through pure culture and molecular techniques ( Fuhrman , 2009 ) . Pure culture providing a very narrow picture of some of the rarer species present , < 1-5 % of bacteria present ( Fuhrman , 2009 ) . Molecular techniques , such as Sanger sequencing , resulting in a much broader scope but highlighting the more abundant species present ( Heidelberg et al. , 2010 ) ( Pedros-Alio , 2007 ) . Neither technique captures all of the diversity present . Alternatively high throughput sequencing , `` tag sequencing '' , divides unique rRNA tag sequences into operational taxonomic units ( OTUs ) based upon similarities in mitochondrial-encoded cytochrome oxidases ( Sogin et al. , 2006 ) . Both Sanger , shot gun sequencing , and tag sequencing organize sequences into OTUs ( Heidelberg et al. , 2010 ) . However , it is the resolution that tag sequencing provides that sets it apart , resulting from the increased efficiency in serial analysis ( Heidelberg et al. , 2010 ) . This efficiency increase is made possible through the use of internal primer sequences resulting in restriction-digest overhanging sequences ( Heidelberg et al. , 2010 ) . Though OTUs provide a means of distinguishing the possible number of phylogenetic groups , it is not possible to deduce phylogenetic relationships based upon OTU 's . Tags associated with OTUs must be cross-referenced with gene banks , in order for tags to be phylotyped and relationships established ( Sogin et al. , 2006 ) . The result of tag sequencing has been to produce orders of magnitude larger estimates of OTUs present in ecosystems , producing a long tail on species abundance curves ( Patterson , 2009 ) ( Pedrós-Alío , 2007 ) . This long tail accounts for less than .1 % of the abundant species in a particular ecosystem . At the same time it represents thousands of populations accounting for most of the phylogenetic diversity in an ecosystem . This low-abundance high-diversity group is what is now called the `` Rare Biosphere '' . Using this method , Sogin et al. 's study of microbial diversity in North Atlantic deep water produced an estimate of 5266 different taxa ( Sogin et al. , 2006 ) . This is particularly dramatic considering that previous studies employing more traditional PCR cloning techniques have resulted in estimates of up to 500 ( Pedrós-Alío , 2007 ) .", "qid": "568", "docid": "Rare_biosphere", "rank": 73, "score": 104937 }, { "content": "Title: Census of Antarctic Marine Life Content: The Census of Antarctic Marine Life ( CAML ) is a field project of the Census of Marine Life that researches the marine biodiversity of Antarctica , how it is affected by climate change , and how this change is altering the ecosystem of the Southern Ocean .

Much of the carbon in the peat deposits produced by coal forests came from photosynthetic splitting of existing carbon dioxide , which released the accompanying split-off oxygen into the atmosphere . This process may have greatly increased the oxygen level , possibly as high as about 35 % , making the air more easily breathable by animals with inefficient respiratory systems , as indicated by the size of Meganeura compared to modern dragonflies . Coal forests covered tropical Euramerica ( Europe , eastern North America , northwesternmost Africa ) and Cathaysia ( mainly China ) . Climate change devastated these tropical rainforests during the Carboniferous period . The Carboniferous Rainforest Collapse was caused by a cooler drier climate that initially fragmented , then collapsed the rainforest ecosystem . During most of the rest of Carboniferous times , the coal forests were mainly restricted to refugia in North America ( such as the Appalachian and Illinois coal basins ) and central Europe . At the very end of the Carboniferous period , the coal forests underwent a resurgence , expanding mainly in eastern Asia , notably China ; they never recovered fully in Euramerica . The Chinese coal forests continued to flourish well into Permian times . This resurgence of the coal forests in very late Carboniferous times seems to have coincided with a lowering of global temperatures and a return of extensive polar ice in southern Gondwana , perhaps due to lessening of the greenhouse effect as the massive coal deposition process abstracted carbon dioxide from the atmosphere .", "qid": "568", "docid": "Coal_forest", "rank": 81, "score": 103468 }, { "content": "Title: Julie Palais Content: Julie Michelle Palais ( * September 2 , 1956 in Massachusetts ) is an award-winning polar glaciologist who has made great contributions to climate change research studying volcanic fallout in ice cores from both Greenland and Antarctica .

The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation . About one third of the land surface of the world is arid or semi-arid . This includes much of the polar regions where little precipitation occurs and which are sometimes called polar deserts or `` cold deserts '' . Deserts can be classified by the amount of precipitation that falls , by the temperature that prevails , by the causes of desertification or by their geographical location . Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks which consequently break in pieces . Although rain seldom occurs in deserts , there are occasional downpours that can result in flash floods . Rain falling on hot rocks can cause them to shatter and the resulting fragments and rubble strewn over the desert floor is further eroded by the wind . This picks up particles of sand and dust and wafts them aloft in sand or dust storms . Wind-blown sand grains striking any solid object in their path can abrade the surface . Rocks are smoothed down , and the wind sorts sand into uniform deposits . The grains end up as level sheets of sand or are piled high in billowing sand dunes . Other deserts are flat , stony plains where all the fine material has been blown away and the surface consists of a mosaic of smooth stones . These areas are known as desert pavements and little further erosion takes place . Other desert features include rock outcrops , exposed bedrock and clays once deposited by flowing water . Temporary lakes may form and salt pans may be left when waters evaporate . There may be underground sources of water in the form of springs and seepages from aquifers . Where these are found , oases can occur . Plants and animals living in the desert need special adaptations to survive in the harsh environment . Plants tend to be tough and wiry with small or no leaves , water-resistant cuticles and often spines to deter herbivory . Some annual plants germinate , bloom and die in the course of a few weeks after rainfall while other long-lived plants survive for years and have deep root systems able to tap underground moisture . Animals need to keep cool and find enough food and water to survive . Many are nocturnal and stay in the shade or underground during the heat of the day . They tend to be efficient at conserving water , extracting most of their needs from their food and concentrating their urine . Some animals remain in a state of dormancy for long periods , ready to become active again when the rare rains fall . They then reproduce rapidly while conditions are favorable before returning to dormancy . People have struggled to live in deserts and the surrounding semi-arid lands for millennia . Nomads have moved their flocks and herds to wherever grazing is available and oases have provided opportunities for a more settled way of life . The cultivation of semi-arid regions encourages erosion of soil and is one of the causes of increased desertification . Desert farming is possible with the aid of irrigation and the Imperial Valley in California provides an example of how previously barren land can be made productive by the import of water from an outside source .

[ { "content": "Title: Schottky anomaly Content: The Schottky anomaly is an effect observed in solid-state physics where the specific heat capacity of a solid at low temperature has a peak . It is called anomalous because the heat capacity usually increases with temperature , or stays constant . It occurs in systems with a limited number of energy levels so that E ( T ) increases with sharp steps , one for each energy level that becomes available . Since Cv = ( dE/dT ) , it will experience a large peak as the temperature crosses over from one step to the next . This effect can be explained by looking at the change in entropy of the system . At zero temperature only the lowest energy level is occupied , entropy is zero , and there is very little probability of a transition to a higher energy level . As the temperature increases , there is an increase in entropy and thus the probability of a transition goes up . As the temperature approaches the difference between the energy levels there is a broad peak in the specific heat corresponding to a large change in entropy for a small change in temperature . At high temperatures all of the levels are populated evenly , so there is again little change in entropy for small changes in temperature , and thus a lower specific heat capacity . For a two level system the specific heat coming from the Schottky anomaly has the form : Where kBΔ is the energy between the two levels . This anomaly is usually seen in paramagnetic salts or even ordinary glass ( due to paramagnetic iron impurities ) at low temperature . At high temperature the paramagnetic spins have many spin states available , but at low temperatures some of the spin states are `` frozen out '' ( having too high energy due to crystal field splitting ) , and the entropy per impurity is lowered .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

Both Pioneer spacecraft are escaping the Solar System , but are slowing under the influence of the Sun 's gravity . Upon very close examination of navigational data , the spacecraft were found to be slowing slightly more than expected . The effect is an extremely small acceleration towards the Sun , of , which is equivalent to a reduction of the outbound velocity by 1 km/h over a period of ten years .

The last communication with either spacecraft was in 2003 , but analysis of recorded data continues . Various explanations , both of spacecraft behavior and of gravitation itself , were proposed to explain the anomaly . Over the period 1998 -- 2012 , one particular explanation became accepted . The spacecraft , which are surrounded by an ultra-high vacuum and are each powered by a radioisotope thermoelectric generator ( RTG ) , can shed heat only via thermal radiation . If , due to the design of the spacecraft , more heat is emitted in a particular direction -- what is known as a radiative anisotropy -- then the spacecraft would accelerate slightly in the direction opposite of the excess emitted radiation due to the recoil of thermal photons -- thermal recoil force . If the excess radiation and attendant radiation pressure were pointed in a general direction opposite the Sun , the spacecraft 's velocity away from the Sun would be decreasing at a rate greater than could be explained by previously recognized forces , such as gravity and trace friction , due to the interplanetary medium ( imperfect vacuum ) . By 2012 several papers by different groups , all reanalyzing the thermal radiation pressure forces inherent in the spacecraft , showed that a careful accounting of this explains the entire anomaly , and thus the cause was mundane and did not point to any new phenomena or need for a different physical paradigm .

The internal energy of a thermally isolated system may therefore change due to the exchange of work energy . The entropy of a thermally isolated system will increase in time if it is not at equilibrium , but as long as it is at equilibrium , its entropy will be at a maximum and constant value and will not change , no matter how much work energy the system exchanges with its environment . To maintain this constant entropy , any exchange of work energy with the environment must therefore be quasistatic in nature , in order to assure that the system remains essentially at equilibrium during the process . The opposite of a thermally isolated system is a thermally open system , which allows the transfer of heat energy and entropy . Thermally open systems may vary , however , in the rate at which they equilibrate , depending on the nature of the boundary of the open system . At equilibrium , the temperatures on both sides of a thermally open boundary are equal .

It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide . A GWP is calculated over a specific time interval , commonly 20 , 100 , or 500 years . GWP is expressed as a factor of carbon dioxide ( whose GWP is standardized to 1 ) . In the Fifth Assessment Report of the Intergovernmental Panel on Climate Change , methane has a lifetime of 12.4 years and with climate-carbon feedbacks a global warming potential of 86 over 20 years and 34 over 100 years in response to emissions . User related choices such as the time horizon can greatly affect the numerical values obtained for carbon dioxide equivalents . For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph . Because the GWP of a greenhouse gas depends directly on its infrared spectrum , the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change .", "qid": "575", "docid": "Global_warming_potential", "rank": 24, "score": 91055 }, { "content": "Title: 2007 European heat wave Content: The 2007 European heatwave was a heat wave that affected most of Southern Europe and the Balkans .

It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere , such as from deforestation and the burning of fossil fuels , partially offset by human caused increases in aerosols ; natural changes had little effect .

Individual scientists , universities , and laboratories contribute to the overall scientific opinion via their peer-reviewed publications , and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys . National and international science academies and scientific societies have assessed current scientific opinion on global warming . These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change . The IPCC Fourth Assessment Report stated that : Warming of the climate system is unequivocal , as evidenced by increases in global average air and ocean temperatures , the widespread melting of snow and ice , and rising global average sea level .

Some of the effects in temperate and polar regions will be positive and others elsewhere will be negative .

In some theories of fermions with chiral symmetry , the quantization may lead to the breaking of this ( global ) chiral symmetry . In that case , the charge associated with the chiral symmetry is not conserved . The non-conservation happens in a tunneling process from one vacuum to another . Such a process is called an instanton . In the case of a symmetry related to the conservation of a fermionic particle number , one may understand the creation of such particles as follows . The definition of a particle is different in the two vacuum states between which the tunneling occurs ; therefore a state of no particles in one vacuum corresponds to a state with some particles in the other vacuum . In particular , there is a Dirac sea of fermions and , when such a tunneling happens , it causes the energy levels of the sea fermions to gradually shift upwards for the particles and downwards for the anti-particles , or vice versa . This means particles which once belonged to the Dirac sea become real ( positive energy ) particles and particle creation happens . Technically , an anomalous symmetry is a symmetry of the action , but not of the measure and therefore not of the generating functional of the quantized theory ( ℏ is Planck 's action-quantum divided by 2π ) . The measure consists of a part depending on the fermion field and a part depending on its complex conjugate . The transformations of both parts under a chiral symmetry do not cancel in general .

In geochemistry a europium anomaly is said to be `` positive '' if the Eu concentration in the mineral is enriched relative to the other rare earth elements ( REEs ) and is said to be `` negative '' if Eu is depleted relative to the other REEs . While all lanthanides form relatively large trivalent ( 3 + ) ions , Eu and cerium ( Ce ) have additional valences , europium forms 2 + ions , and Ce forms 4 + ions , leading to chemical reaction differences in how these ions can partition versus the 3 + REEs . In the case of Eu , its reduced divalent ( 2 + ) cations are similar in size and carry the same charge as Ca2 + , an ion found in plagioclase and other minerals . While Eu is an incompatible element in its trivalent form ( Eu3 + ) in an oxidizing magma , it is preferentially incorporated into plagioclase in its divalent form ( Eu2 + ) in a reducing magma where it substitutes for calcium ( Ca2 + ) . Enrichment or depletion is generally attributed to europium 's tendency to be incorporated into plagioclase preferentially over other minerals . If a magma crystallizes stable plagioclase , most of the Eu will be incorporated into this mineral causing a higher than expected concentration of Eu in the mineral versus other REE in that mineral ( a positive anomaly ) . The rest of the magma will then be relatively depleted in Eu with a concentration of Eu lower than expected versus the concentrations of other REEs in that magma . If the Eu-depleted magma is then separated from its plagioclase crystals and subsequently solidifies , its chemical composition will display a negative Eu anomaly ( because the Eu is locked up in the plagioclase left in the magma chamber ) . Conversely , if a magma accumulates plagioclase crystals before solidification , its rock composition will display a relatively positive Eu anomaly . A well-known example of the Eu anomaly is seen on the moon .

It should not be confused with the Thermoelectric effect ( specifically , the Peltier effect ) , in which a temperature difference occurs when a current is driven through an electric junction with two dissimilar conductors . The underlying mechanism of the effect is not fully established ; in particular , different textbooks give conflicting explanations . However , as with any isolated ( adiabatic ) temperature change , the effect comes from the voltage raising or lowering the entropy of the system . ( The magnetocaloric effect is an analogous , but better-known and understood , phenomenon . ) Electrocaloric materials were the focus of significant scientific interest in the 1960s and 1970s , but were not commercially exploited as the electrocaloric effects were insufficient for practical applications , the highest response being 2.5 degrees Celsius under an applied potential of 750 volts . In March 2006 it was reported in the journal Science that thin films of the material PZT ( a mixture of lead , titanium , oxygen and zirconium ) showed the strongest electrocalorific response yet reported , with the materials cooling down by as much as ~ 12 K ( 12 ° C ) for an electric field change of 480 kV/cm , at an ambient temperature of 220 ° C ( 430 ° F ) . The device structure consisted of a thin film ( PZT ) on top of a much thicker substrate , but the figure of 12 K represents the cooling of the thin film only . The net cooling of such a device would be lower than 12 K due to the heat capacity of the substrate to which it is attached . Along the same lines , in 2008 , it was shown that a ferroelectric polymer can also achieve 12 K of cooling , nearer room temperature .

Though subject internally to its own gravity , an isolated system is usually taken to be outside the reach of external gravitational and other long-range forces . This can be contrasted with what ( in the more common terminology used in thermodynamics ) is called a closed system , being enclosed by selective walls through which can pass energy as heat or work , but not matter ; and with an open system , which both matter and energy can enter or exit , though it may have variously impermeable walls in parts of its boundaries . An isolated system obeys the conservation law that its total energy -- mass stays constant . Most often , in thermodynamics , matter and energy are treated as separately conserved . Because of the requirement of enclosure , and the near ubiquity of gravity , strictly and ideally isolated systems do not actually occur in experiments or in nature . Though very useful , they are thus hypothetical concepts only . Classical thermodynamics is usually presented as postulating the existence of isolated systems . It is also usually presented as the fruit of experience . Obviously , no experience has been reported of an ideally isolated system . It is , however , the fruit of experience that some physical systems , including isolated ones , do seem to reach their own states of internal thermodynamic equilibrium . Classical thermodynamics postulates the existence of systems in their own states of internal thermodynamic equilibrium . This postulate is a very useful idealization . In the attempt to explain the idea of gradual approach to thermodynamic equilibrium after a thermodynamic operation , with entropy increase according to the second law of thermodynamics , Boltzmann 's H-theorem used equations which assumed a system ( for example , a gas ) was isolated . That is , all the mechanical degrees of freedom could be specified , treating the enclosing walls simply as mirror boundary conditions . This led to Loschmidt 's paradox . If , however , the stochastic behavior of the molecules and thermal radiation in real enclosing walls is considered , then the system is in effect in a heat bath . Then Boltzmann 's assumption of molecular chaos can be justified . The concept of an isolated system can serve as a useful model approximating many real-world situations . It is an acceptable idealization used in constructing mathematical models of certain natural phenomena ; e.g. , the planets in the Solar System , and the proton and electron in a hydrogen atom are often treated as isolated systems . But from time to time , a hydrogen atom will interact with electromagnetic radiation and go to an excited state .

A Ce anomaly is said to be `` negative '' if Ce is depleted relative to the other REEs and is said to be `` positive '' if Ce is enriched relative to the other REEs . Cerium is a rare earth element ( lanthanide ) characterized by two different redox states : III and IV . Contrary to other lanthanide elements which are only trivalent ( with the notable exception of Eu2 + ) , Ce3 + can be oxidized by atmospheric oxygen ( O2 ) to Ce4 + under alkaline conditions . The cerium anomaly relates to the decrease in solubility which accompanies the oxidation of Ce ( III ) to Ce ( IV ) .

Sediments deposited under oxic or anoxic conditions can preserve on the long term the geochemical signature of Ce3 + or Ce4 + upon reserve that no early diagenetic transformation altered it .

Thomas et al. , ( 2003 ) state that `` terrestrial zircons commonly show a positive Ce anomaly due to the incorporation of Ce4 + into zircon , which is because Ce4 + has the same charge and a similar ionic radius than Zr4 + ( Ce4 + = 0.97 Å ; Zr4 + = 0.84 Å ) '' . As such , Ce4 + is incorporated into zircon much more easily than the larger Ce3 + ( ionic radius = 1.143 Å ) .

Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans .

Feedback in general is the process in which changing one quantity changes a second quantity , and the change in the second quantity in turn changes the first . Positive feedback amplifies the change in the first quantity while negative feedback reduces it . The term `` forcing '' means a change which may `` push '' the climate system in the direction of warming or cooling . An example of a climate forcing is increased atmospheric concentrations of greenhouse gases . By definition , forcings are external to the climate system while feedbacks are internal ; in essence , feedbacks represent the internal processes of the system . Some feedbacks may act in relative isolation to the rest of the climate system ; others may be tightly coupled ; hence it may be difficult to tell just how much a particular process contributes . Forcings , feedbacks and the dynamics of the climate system determine how much and how fast the climate changes . The main positive feedback in global warming is the tendency of warming to increase the amount of water vapor in the atmosphere , which in turn leads to further warming . The main negative feedback comes from the Stefan -- Boltzmann law , the amount of heat radiated from the Earth into space changes with the fourth power of the temperature of Earth 's surface and atmosphere . Some observed and potential effects of global warming are positive feedbacks , which contribute directly to further global warming .

Reconstructions have consistently shown that the rise in the instrumental temperature record of the past 150 years is not matched in earlier centuries , and the name `` hockey stick graph '' was coined for figures showing a long-term decline followed by an abrupt rise in temperatures . These graphs were publicised to explain the scientific findings of climatology , and in addition to scientific debate over the reconstructions , they have been the topic of political dispute . The issue is part of the global warming controversy and has been one focus of political responses to reports by the Intergovernmental Panel on Climate Change ( IPCC ) . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . The use of proxy indicators to get quantitative estimates of the temperature record of past centuries was developed from the 1990s onwards , and found indications that recent warming was exceptional . The reconstruction introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large-scale reconstructions , and its findings were disputed by Patrick Michaels at the United States House Committee on Science . In 1998 , Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 . In ( MBH99 ) the methodology was extended back to 1000 . The term hockey stick was coined by the climatologist Jerry D. Mahlman , to describe the pattern this showed , envisaging a graph that is relatively flat to 1900 as forming an ice hockey stick 's `` shaft '' , followed by a sharp increase corresponding to the `` blade '' . A version of this graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , along with four other reconstructions supporting the same conclusion . The graph was publicised , and became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th-century warmth was exceptional . Those disputing the graph included Pat Michaels , the George C. Marshall Institute and Fred Singer . A paper by Willie Soon and Sallie Baliunas claiming greater medieval warmth was used by the Bush administration chief of staff Philip Cooney to justify altering the first Environmental Protection Agency Report on the Environment . The paper was quickly dismissed by scientists in the Soon and Baliunas controversy , but on July 28 , Republican Jim Inhofe spoke in the Senate citing it to claim `` that man-made global warming is the greatest hoax ever perpetrated on the American people '' . Later in 2003 , a paper by Steve McIntyre and Ross McKitrick disputing the data used in MBH98 paper was publicised by the George C. Marshall Institute and the Competitive Enterprise Institute . In 2004 , Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 , McIntyre and McKitrick published criticisms of the principal component analysis methodology as used in MBH98 and MBH99 . The analysis therein was subsequently disputed by published papers , including and , which pointed to errors in the McIntyre and McKitrick methodology . In June 2005 , Rep. Joe Barton launched what Sherwood Boehlert , chairman of the House Science Committee , called a `` misguided and illegitimate investigation '' into the data , methods and personal information of Mann , Bradley and Hughes . At Boehlert 's request , a panel of scientists convened by the National Research Council was set up , which reported in 2006 , supporting Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result . Barton and U.S. Rep. Ed Whitfield requested Edward Wegman to set up a team of statisticians to investigate , and they supported McIntyre and McKitrick 's view that there were statistical failings , although they did not quantify whether there was any significant effect . They also produced an extensive network analysis which has been discredited by expert opinion and found to have issues of plagiarism . Arguments against the MBH studies were reintroduced as part of the Climatic Research Unit email controversy , but dismissed by eight independent investigations . More than two dozen reconstructions , using various statistical methods and combinations of proxy records , have supported the broad consensus shown in the original 1998 hockey-stick graph , with variations in how flat the pre-20th century `` shaft '' appears . The 2007 IPCC Fourth Assessment Report cited 14 reconstructions , 10 of which covered 1,000 years or longer , to support its strengthened conclusion that it was likely that Northern Hemisphere temperatures during the 20th century were the highest in at least the past 1,300 years .

In the current episode of global warming many such 15-year periods appear in the surface temperature record , along with robust evidence of the long-term warming trend ; climate is classically averaged over 30-year periods . Publicity has surrounded claims of a global warming hiatus during the period 1998 -- 2013 . The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend , and so subsequent annual temperatures gave the appearance of a hiatus : by January 2006 , it appeared to some that global warming had stopped or paused . A 2009 study showed that decades without warming were not exceptional , and in 2011 a study showed that if allowances were made for known variability , the rising temperature trend continued unabated . There was increased public interest in 2013 in the run-up to publication of the IPCC Fifth Assessment Report , and despite concerns that a 15-year period was too short to determine a meaningful trend , the IPCC included a section on a hiatus , which it defined as a much smaller increasing linear trend over the 15 years from 1998 to 2012 , than over the 60 years from 1951 to 2012 . Various studies examined possible causes of the short-term slowdown . Even though the overall climate system has continued to accumulate energy due to Earth 's positive energy budget , the available temperature readings at the Earth 's surface indicate slower rates of increase in surface warming than in the prior decade . Since measurements at the top of the atmosphere show that Earth is receiving more energy than it is radiating back into space , the retained energy should be producing warming in the Earth 's climate system . Research reported in July 2015 on an updated NOAA dataset casts doubt on the existence of a hiatus , and it finds no indication of a slowdown even in earlier years . Scientists working on other datasets welcomed this study , though they have expressed the view that the recent warming trend was less than in previous periods of the same length . Subsequently , a detailed study supports the conclusion that warming is continuing , but it also find there was less warming between 2001 and 2010 than climate models had predicted , and that this slowdown might be attributed to short-term variations in the Pacific decadal oscillation ( PDO ) , which was negative during that period . Another review finds `` no substantive evidence '' of a pause in global warming . A statistical study of global temperature data since 1970 concludes that the term ` hiatus ' or ` pause ' is not justified . Independent of these discussions about data and measurements for earlier years , 2015 turned out to be much warmer than any of the earlier years , already before El Niño conditions started . The warmth of 2015 largely ended any remaining scientific credibility of claims that the supposed `` hiatus '' since 1998 had any significance for the long-term warming trend . In January 2017 , a study published in the journal Science Advances cast further doubt on the existence of a recent pause , with more evidence that ocean temperatures have been underestimated . An April 2017 study found the data consistent with a steady warming trend globally since the 1970s , with fluctuations within the expected range of short term variability .", "qid": "575", "docid": "Global_warming_hiatus", "rank": 85, "score": 81466 }, { "content": "Title: Effects of global warming Content: The effects of global warming are the environmental and social changes caused ( directly or indirectly ) by human emissions of greenhouse gases .

This facility provides the means to make precise measurements of their decay modes . The absence of most or all of the electrons in the ions simplifies theoretical treatments of their influence on the decay . Also , such a high degree of ionization is typical in stellar environments where such decays play an important role in nucleosynthesis . In 2007 an ESR experiment reported the observation of unexpected modulation in time of the rate of electron capture decays of highly ionized heavy atoms -- 140Pr58 + , which have a lifetime of 3.39 min . Such findings were soon repeated by the same group , and extended to include the decay of 142Pm60 + ( lifetime 40.5 s ) . The oscillations in decay rate had time periods near to 7 s and amplitudes of about 20 % . Such a phenomenon had not been previously observed , and was difficult to understand . The experimental group considered it very improbable that the appearance of the phenomenon is due to a technical artefact because they report that their detection technique provides -- during the whole observation time -- complete and uninterrupted information upon the status of each stored ion . As this type of weak decay involves the production of an electron neutrino , attempts have been made to relate the observed oscillations to neutrino oscillations , but this proposal was highly controversial . In 2013 , a similar experimental group at the ESR now called the Two-Body-Weak-Decays Collaboration reported further observations of the phenomenon with measurements on 142Pm60 + with much higher precision in period and amplitude . The same period was observed , but the amplitude was only about a half of that previously seen . Based on the assumption that the measurements have no serious flaws , as of 2017 of order fifty articles have been published offering and debating various possible theoretical explanations for the oscillating modulations . No consensus has emerged . An example of a proposed explanation relates to the difference in mass of neutrino mass eigenstates , but not through the well-known neutrino flavour oscillations . It is proposed that the quantum state of the daughter ion is `` prematurely '' disentangled from that of the co-produced neutrino by the ion 's motion in its circular orbit guided by the magnetic fields of the storage ring magnets , well before detection of the ion . ( Such disentanglement is usually caused by detection of the daughter in experiments not using a storage ring . ) A probability amplitude for the ion circulating in the ring for a given time before detection is calculated to depend on the neutrino mass , so that the corresponding probability including all neutrino mass eigenstates would include an interference term involving the neutrino mass difference . The oscillation period estimated in this scheme is within an order of magnitude of that observed .", "qid": "575", "docid": "GSI_anomaly", "rank": 97, "score": 80419 }, { "content": "Title: Runaway greenhouse effect Content: A runaway greenhouse effect is a process in which a net positive feedback between surface temperature and atmospheric opacity increases the strength of the greenhouse effect on a planet until its oceans boil away .

Low-altitude stratus clouds form over the cool water of the California Current , and spread overnight into the coastal regions of Southern California . The overcast skies often are accompanied by fog and drizzle , though usually not rain . June Gloom usually clears up between mid-morning and early afternoon , depending on the strength of the marine layer , and gives way to sunny skies . On a strong June Gloom day , the clouds and fog may extend inland to the valleys and Inland Empire and may persist into the mid-afternoon or evening . A combination of atmospheric and oceanic conditions must be just right in order for June Gloom to form , and these conditions usually align only around May and June of each year . These include the marine layer effect common to the west coast of the United States , an atmospheric inversion caused by subsidence of high-pressure air from the subtropical ridge , and sufficiently cool ocean water off the coast . The June Gloom pattern is also enhanced by the Catalina eddy local to southern California . May and June together are usually the cloudiest months in coastal Southern California . June Gloom is stronger in years associated with a La Niña , and weaker or nonexistent in years with an El Niño . This weather pattern is relatively rare , and occurs only in a few other parts of the world where climates and conditions are similar .

Seasons result from the yearly orbit of the Earth around the Sun and the tilt of the Earth 's rotational axis relative to the plane of the orbit . In temperate and polar regions , the seasons are marked by changes in the intensity of sunlight that reaches the Earth 's surface , variations of which may cause animals to go into hibernation or to migrate , and plants to be dormant . During May , June , and July , the northern hemisphere is exposed to more direct sunlight because the hemisphere faces the sun . The same is true of the southern hemisphere in November , December , and January . It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux . However , due to seasonal lag , June , July , and August are the hottest months in the northern hemisphere and December , January , and February are the hottest months in the southern hemisphere . In temperate and subpolar regions , four calendar-based seasons are generally recognized : spring , autumn or fall , and winter . Ecologists often use a six-season model for temperate climate regions : prevernal , vernal , estival , serotinal , autumnal , and hibernal . Many tropical regions have two seasons : the rainy , wet , or monsoon season and the dry season . Some have a third cool , mild , or harmattan season . Seasons often held special significance for agrarian societies , whose lives revolved around planting and harvest times , and the change of seasons was often attended by ritual . In some parts of the world , some other `` seasons '' capture the timing of important ecological events such as hurricane season , tornado season , and wildfire season .

This happens twice each year ( once in each hemisphere ) , at which times the Sun reaches its highest position in the sky as seen from the north or the south pole . The summer solstice occurs during the hemisphere 's summer . This is the northern solstice in the northern hemisphere and the southern solstice in the southern hemisphere . Depending on the shift of the calendar , the summer solstice occurs some time between June 20 and June 22 in the northern hemisphere and between December 20 and December 23 each year in the southern hemisphere . The same dates in the opposite hemisphere are referred to as the winter solstice . When on a geographic pole , the Sun reaches its greatest height at the moment of solstice . It can be noon only along that longitude which at that moment lies in the direction of the Sun from the pole . For other longitudes , it is not noon . Noon has either passed or has yet to come . Hence the notion of a solstice day is useful . The term is colloquially used like `` midsummer '' to refer to the day on which solstice occurs .

Over 99 % of outgoing longwave radiation has wavelengths between 4 µm and 100 µm , in the thermal infrared part of the electromagnetic spectrum .

Once this warm surge inundated the area , a remarkably prolonged period of record setting temperatures ensued . NOAA 's National Climate Data Center reported that over 7,000 daily record high temperatures were tied or broken from 1 March through 27 March . In some places the temperature exceeded 86 ° F ( 30 ° C ) . For instance , in Grand Rapids , Michigan , the highest temperature recorded was 87 ° F on March 21 ; in Chicago a high of 87 ° F was also recorded on that same day . Records were broken in unusual ways . Chicago , for example , saw temperatures above 80 ° F every day between March 14 -- 18 , breaking records on all five days .

In context , the National Weather Service 's Chicago branch noted that Chicago typically averages only one day in the 80 's in April . And only once in 140 years of weather observations has April produced as many 80 ° F days as this March . In Traverse City , Michigan one day began with a low temperature ( 67 ° F ) higher than the previous record high for the day . Temperature records across much of southern Canada also were shattered . Some of the most impressive readings came from Nova Scotia on March 22 , when the mercury climbed to 30.0 C at a climate station in Lake Major , making it the highest March temperature recorded in Nova Scotia , and the third highest March temperature recorded in Canada . That same day , the temperature hit 29.2 C at Western Head , Nova Scotia . The heat reached as far east as Cape Breton Island , with the temperature climbing to 24.0 C at Sydney , Nova Scotia on March 22 , a place historically surrounded by ice-jammed waters , frigid winds , and snow in March . The week of March 18 also set record temperatures in Manitoba and much of Ontario as well as into the Maritime Provinces .

Averaged over the seven-day period from March 16 to March 22 inclusive , nearly the entire area of the Midwest and Northeast U.S. and most of Ontario and Quebec had temperatures 10 ° C ( 18 ° F ) or more above the 1981-2010 average . Even more dramatically , most of Iowa and Minnesota , all of Wisconsin and Michigan , and most of southeastern Ontario had seven-day mean temperatures more than 15 ° C ( 27 ° F ) above the climatological average for the same period . An 84 ° F high at Madison , WI in early March was 43 ° F above average and followed an overnight low of 60 ° F , 35 degrees above normal the daily high being more than seven standard deviations above the mean . The absolute temperature and departure statistically would be equivalent to a mid-July high at that station in excess of 125 ° F or more ; the highest temperature recorded there was 107 ° at least once during the heat waves of the middle 1930s . This mild warm spell brought out spring peepers in northern Ontario on 23 March , which are usually not heard until mid-to-late April , or sometimes early May .

All matter with a temperature greater than absolute zero emits thermal radiation . When the temperature of a body is greater than absolute zero , inter-atomic collisions cause the kinetic energy of the atoms or molecules to change . This results in charge-acceleration and/or dipole oscillation which produces electromagnetic radiation , and the wide spectrum of radiation reflects the wide spectrum of energies and accelerations that occur even at a single temperature . Examples of thermal radiation include the visible light and infrared light emitted by an incandescent light bulb , the infrared radiation emitted by animals is detectable with an infrared camera , and the cosmic microwave background radiation . Thermal radiation is different from thermal convection and thermal conduction -- a person near a raging bonfire feels radiant heating from the fire , even if the surrounding air is very cold . Sunlight is part of thermal radiation generated by the hot plasma of the Sun . The Earth also emits thermal radiation , but at a much lower intensity and different spectral distribution ( infrared rather than visible ) because it is cooler . The Earth 's absorption of solar radiation , followed by its outgoing thermal radiation are the two most important processes that determine the temperature and climate of the Earth . If a radiation-emitting object meets the physical characteristics of a black body in thermodynamic equilibrium , the radiation is called blackbody radiation . Planck 's law describes the spectrum of blackbody radiation , which depends only on the object 's temperature . Wien 's displacement law determines the most likely frequency of the emitted radiation , and the Stefan -- Boltzmann law gives the radiant intensity .

For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) .

It was launched in 2005 to fight Global warming and is a major pillar of EU climate policy . As of 2013 , the EU ETS covers more than 11,000 factories , power stations , and other installations with a net heat excess of 20 MW in 31 countries -- all 28 EU member states plus Iceland , Norway , and Liechtenstein . In 2008 , the installations regulated by the EU ETS were collectively responsible for close to half of the EU 's anthropogenic emissions of CO2 and 40 % of its total greenhouse gas emissions . Under the ` cap and trade ' principle , a maximum ( cap ) is set on the total amount of greenhouse gases that can be emitted by all participating installations . ` Allowances ' for emissions are then auctioned off or allocated for free , and can subsequently be traded . Installations must monitor and report their CO2 emissions , ensuring they hand in enough allowances to the authorities to cover their emissions . If emission exceeds what is permitted by its allowances , an installation must purchase allowances from others . Conversely , if an installation has performed well at reducing its emissions , it can sell its leftover credits . This allows the system to find the most cost-effective ways of reducing emissions without significant government intervention . The scheme has been divided into a number of `` trading periods '' . The first ETS trading period lasted three years , from January 2005 to December 2007 . The second trading period ran from January 2008 until December 2012 , coinciding with the first commitment period of the Kyoto Protocol . The third trading period began in January 2013 and will span until December 2020 . Compared to 2005 , when the EU ETS was first implemented , the proposed caps for 2020 represents a 21 % reduction of greenhouse gases . This target has been reached 6 years early as emissions in the ETS fell to 1812 mln tonnes in 2014 . The EU ETS has seen a number of significant changes , with the first trading period described as a ` learning by doing ' phase . Phase III sees a turn to auctioning a majority of permits rather than allocating freely ; harmonisation of rules for the remaining allocations ; and the inclusion of other greenhouse gases , such as nitrous oxide and perfluorocarbons . In 2012 , the EU ETS was also extended to the airline industry , though this has been paused for one year given the possibility of a global system for these emissions . The price of EU ETS carbon credits has been lower than intended , with a large surplus of allowances , in part because of the impact of the recent economic crisis on demand . In 2012 , the Commission said it would delay the auctioning of some allowances . Currently legislation is under way which would introduce a Market Stability Reserve to the EU ETS that adjusts the annual supply of CO2 permits based on the CO2 permits in circulation . Overall , since its conception , the EU ETS has been characterized by relatively high levels of policy uncertainty . This uncertainty has been both technical , in terms of its detailed rules and procedures , and political , in terms of its public , industry , and governmental support .

Air pollution occurs when harmful substances are released into the Earth 's atmosphere . These pollutants are released through human activity and natural sources .

Through the transition to renewable energy sources , Germany has become the climate change policy leader and renewable energy leader in the European Union ( EU ) and in the world with ambitious climate change programs . The current goal of the German government was approved on 14 November 2016 in the German Climate Action Plan 2050 , which outlines measures by which Germany can meet its greenhouse gas emissions by 2050 . By 2050 , Germany wants to reduce their GHGs by 80 to 95 % and by 2030 they want to reduce it by 55 % , compared to the EU target of 40 % . In order to achieve these goals , a variety of strategies and policies are used rather than legislation . The four strategies the German government bases air pollution control on are laying down environmental quality standards , emission reduction requirements according to the best available technology , production regulations , and laying down emission ceilings . Through these strategies , policy instruments have been put in place that have contributed to the success of the significant air pollution reduction in Germany . These instruments include the Federal Emission Control Act and Implementing Ordinances , Technical Instructions on Air Quality Control ( TA Luft ) , Amendment to Ordinance on Small Firing Installations , Implementation of the directive on industrial emissions , and Transboundary air pollution control policy . The German Feed-in-Tariff policy introduced in 2000 led to the significant increase in renewable energy use and decreasing air pollution . They have been introduced in Germany to increase the use of renewables , such as wind power , biomass , hydropower , geothermal power , and photovoltaics , thereby reducing GHG emissions causing air pollution and combating climate change .

The third being the growing opposition to the country 's growing reliance on nuclear energy .

Part of this radiation is directed towards the surface , warming it . The downward component of this radiation -- that is , the strength of the greenhouse effect -- will depend on the atmosphere 's temperature and on the amount of greenhouse gases that the atmosphere contains . On Earth , the atmosphere is warmed by absorption of infrared thermal radiation from the underlying surface ( heated by the sun ) , absorption of shorter wavelength radiant energy from the sun , and convective heat fluxes from the surface . Greenhouse gases in the atmosphere radiate energy , some of which is directed to the surface and lower atmosphere .

Polluters are required to hold permits in amount equal to their emissions . Polluters that want to increase their emissions must buy permits from others willing to sell them . Financial derivatives of permits can also be traded on secondary markets . In theory , polluters who can reduce emissions most cheaply will do so , achieving the emission reduction at the lowest cost to society . Cap and trade is meant to provide the private sector with the flexibility required to reduce emissions while stimulating technological innovation and economic growth . There are active trading programs in several air pollutants . For greenhouse gases , which cause climate change , permit units are often called carbon credits . The largest greenhouse gases trading program is the European Union Emission Trading Scheme , which trades primarily in European Union Allowances ( EUAs ) ; the Californian scheme trades in California Carbon Allowances , the New Zealand scheme in New Zealand Units and the Australian scheme in Australian Units .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation . In some areas , policies designed to address global warming may contribute positively towards other development objectives .

The drivers for corporate GHG accounting include mandatory GHG reporting in directors ' reports , investment due diligence , shareholder and stakeholder communication , staff engagement , green messaging , and tender requirements for business and government contracts . Accounting for greenhouse gas emissions is increasingly seen as a standard requirement for business .

As well as the economic cost of lost commodities , fugitive emissions contribute to air pollution and climate change . A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide , or 12 per cent of all greenhouse gases emitted by the sector . Venting of natural gas , flaring , accidental releases and storage losses accounted for an additional 38 per cent . Fugitive emissions present other risks and hazards . Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities . In situations where large amounts of flammable liquids and gases are contained under pressure , leaks also increase the risk of fire and explosion . Leaks from pressurized process equipment generally occur through valves , pipe connections , mechanical seals , or related equipment . Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks . Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks , fugitive emissions can be a significant proportion of total emissions . Though the quantities of leaked gases may be small , gases that have serious health or environmental impacts can cause a significant problem . To minimize and control leaks at process facilities operators carry out regular leak detection and repair activities . Routine inspections of process equipment with gas detectors can be used to identify leaks and estimate the leak rate in order to decide on appropriate corrective action . Proper routine maintenance of equipment reduces the likelihood of leaks . Because of the technical difficulties and costs of detecting and quantifying actual fugitive emissions at a site or facility , and the variability and intermittent nature of emission flow rates , bottom-up estimates based on standard emission factors are generally used for annual reporting purposes . New technologies are under development that could revolutionize the detection and monitoring of fugitive emissions . One technology , known as differential absorption lidar ( DIAL ) , can be used to remotely measure concentration profiles of hydrocarbons in the atmosphere up to several hundred meters from a facility . DIAL has been used for refinery surveys in Europe for over 15 years . A pilot study carried out in 2005 using DIAL found that actual emissions at a refinery were fifteen times higher than those previously reported using the emission factor approach . The fugitive emissions were equivalent to 0.17 % of the refinery throughput . Portable gas leak imaging cameras are also a new technology that can be used to improve leak detection and repair , leading to reduced fugitive emissions .

The UNFCCC measures emissions according to production , rather than consumption ( UK Parliament , 2010 ) . Consequently , embedded emissions on imported goods are attributed to the exporting , rather than the importing , country . The question of whether to measure emissions on production instead of consumption is partly an issue of equity , i.e. , who is responsible for emissions ( Toth et al. , 2001 , p. 670 ) .

That charge , called a carbon price , is the amount that must be paid for the right to emit one tonne of CO2 into the atmosphere . Carbon pricing usually takes the form either of a carbon tax or a requirement to purchase permits to emit , generally known as cap-and-trade , but also called `` allowances '' . Carbon pricing solves the economic problem that , a known greenhouse gas , is what economics calls a negative externality -- a detrimental product that is not priced ( charged for ) by any market . As a consequence of not being priced , there is no market mechanism responsive to the costs of CO2 emitted . The standard economic solution to problems of this type , first proposed by Arthur Pigou in 1920 , is for the product - in this case , CO2 emissions - to be charged at a price equal to the monetary value of the damage caused by the emissions . This should result in the economically optimal ( efficient ) amount of CO2 emissions . Many practical concerns mar the theoretical simplicity of this picture : for example , the exact monetary damage caused by a tonne of CO2 is uncertain . The economics of carbon pricing is much the same for taxes and cap-and-trade . Both prices are efficient ; they have the same social cost and the same effect on profits if permits are auctioned . However , some economists argue that caps prevent non-price policies , such as renewable energy subsidies , from reducing carbon emissions , while carbon taxes do not . Others argue that an enforced cap is the only way to guarantee that carbon emissions will actually be reduced ; a carbon tax will not prevent those who can afford to do so from continuing to generate emissions . The choice of pricing approach , a tax or cap-and-trade , has been controversial . A carbon tax is generally favored on economic grounds for its simplicity and stability , while cap-and-trade is often favored on political grounds .

Carbon offsets are measured in metric tons of carbon dioxide-equivalent ( CO2e ) and may represent six primary categories of greenhouse gases : carbon dioxide , methane ( CH4 ) , nitrous oxide ( N2O ) , perfluorocarbons ( PFCs ) , hydrofluorocarbons ( HFCs ) , and sulfur hexafluoride ( SF6 ) . One carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases . There are two markets for carbon offsets . In the larger , compliance market , companies , governments , or other entities buy carbon offsets in order to comply with caps on the total amount of carbon dioxide they are allowed to emit . This market exists in order to achieve compliance with obligations of Annex 1 Parties under the Kyoto Protocol , and of liable entities under the EU Emission Trading Scheme . In 2006 , about $ 5.5 billion of carbon offsets were purchased in the compliance market , representing about 1.6 billion metric tons of CO2e reductions . In the much smaller , voluntary market , individuals , companies , or governments purchase carbon offsets to mitigate their own greenhouse gas emissions from transportation , electricity use , and other sources . For example , an individual might purchase carbon offsets to compensate for the greenhouse gas emissions caused by personal air travel . Many companies ( see list ) offer carbon offsets as an up-sell during the sales process so that customers can mitigate the emissions related with their product or service purchase ( such as offsetting emissions related to a vacation flight , car rental , hotel stay , consumer good , etc. ) . In 2008 , about $ 705 million of carbon offsets were purchased in the voluntary market , representing about 123.4 million metric tons of CO2e reductions . Some fuel suppliers in the UK offer fuel which has been carbon offset such as Fuel dyes . Offsets are typically achieved through financial support of projects that reduce the emission of greenhouse gases in the short - or long-term . The most common project type is renewable energy , such as wind farms , biomass energy , or hydroelectric dams . Others include energy efficiency projects , the destruction of industrial pollutants or agricultural byproducts , destruction of landfill methane , and forestry projects . Some of the most popular carbon offset projects from a corporate perspective are energy efficiency and wind turbine projects . Carbon offsetting has gained some appeal and momentum mainly among consumers in western countries who have become aware and concerned about the potentially negative environmental effects of energy-intensive lifestyles and economies . The Kyoto Protocol has sanctioned offsets as a way for governments and private companies to earn carbon credits that can be traded on a marketplace . The protocol established the Clean Development Mechanism ( CDM ) , which validates and measures projects to ensure they produce authentic benefits and are genuinely `` additional '' activities that would not otherwise have been undertaken . Organizations that are unable to meet their emissions quota can offset their emissions by buying CDM-approved Certified Emissions Reductions . Emissions from burning fuel , such as red diesel , has pushed one UK fuel supplier to create a carbon offset fuel named Carbon Offset Red Diesel . Offsets may be cheaper or more convenient alternatives to reducing one 's own fossil-fuel consumption . However , some critics object to carbon offsets , and question the benefits of certain types of offsets . Due diligence is recommended to help businesses in the assessment and identification of `` good quality '' offsets to ensure offsetting provides the desired additional environmental benefits , and to avoid reputational risk associated with poor quality offsets . Offsets are viewed as an important policy tool to maintain stable economies and to improve sustainability .

By subsector , road transport is the largest contributor to global warming . Environmental regulations in developed countries have reduced the individual vehicle 's emission ; however , this has been offset by an increase in the number of vehicles , and more use of each vehicle . Some pathways to reduce the carbon emissions of road vehicles considerably have been studied . Energy use and emissions vary largely between modes , causing environmentalists to call for a transition from air and road to rail and human-powered transport , and increase transport electrification and energy efficiency . The transportation sector is a major source of greenhouse gas emissions ( GHGs ) in the United States . An estimated 30 percent of national GHGs are directly attributable to transportation -- and in some regions , the proportion is even higher . Transportation methods are the greatest contributing source of GHGs in the U.S. , accounting for 47 percent of the net increase in total U.S. emissions since 1990 .

Climate change mitigation generally involves reductions in human ( anthropogenic ) emissions of greenhouse gases ( GHGs ) . Mitigation may also be achieved by increasing the capacity of carbon sinks , e.g. , through reforestation . Mitigation policies can substantially reduce the risks associated with human-induced global warming . According to the IPCC 's 2014 assessment report , `` Mitigation is a public good ; climate change is a case of the ` tragedy of the commons . Effective climate change mitigation will not be achieved if each agent ( individual , institution or country ) acts independently in its own selfish interest ( see international cooperation and emissions trading ) , suggesting the need for collective action . Some adaptation actions , on the other hand , have characteristics of a private good as benefits of actions may accrue more directly to the individuals , regions , or countries that undertake them , at least in the short term . Nevertheless , financing such adaptive activities remains an issue , particularly for poor individuals and countries . '' Examples of mitigation include phasing out fossil fuels by switching to low-carbon energy sources , such as renewable and nuclear energy , and expanding forests and other `` sinks '' to remove greater amounts of carbon dioxide from the atmosphere . Energy efficiency may also play a role , for example , through improving the insulation of buildings . Another approach to climate change mitigation is climate engineering .

The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of GHGs at a level that would prevent dangerous human interference of the climate system .

That same La Niña event also had devastating effects in the Eastern states of Australia . The second phase lasted from June 2010 to October 2010 , caused severe heat waves , and multiple record-breaking temperatures . The heatwaves began on April 2010 , when strong anticyclones began to develop , over most of the affected regions , in the Northern Hemisphere . The heatwaves ended in October 2010 , when the powerful anticyclones over most of the affected areas dissipated . The heat wave during the summer of 2010 was at its worst in June , over the Eastern United States , Middle East , Eastern Europe and European Russia , and over Northeastern China and southeastern Russia . June 2010 marked the fourth consecutive warmest month on record globally , at 0.66 ° C ( 1.22 ° F ) above average , while the period April -- June was the warmest ever recorded for land areas in the Northern Hemisphere , at 1.25 ° C ( 2.25 ° F ) above average . The previous record for the global average temperature in June was set in 2005 at 0.66 ° C ( 1.19 ° F ) , and the previous warm record for April -- June over Northern Hemisphere land areas was 1.16 ° C ( 2.09 ° F ) , set in 2007 . Sometime during June 2010 , the highest recorded temperature caused by the heatwave was 53.5 ° C , in Southeastern Russia , just north of Kazakhstan . The strongest of the anticyclones , the one situated over Siberia , registered a maximum high pressure of 1040 millibars . The weather caused forest fires in China , where three in a team of 300 died fighting a fire that broke out in the Binchuan County of Dali , as Yunnan suffered the worst drought in 60 years by February 17 . A major drought was reported across the Sahel as early as January .

In 2013 , the CSIRO released a report stating that Australia is becoming hotter , and that it will experience more extreme heat and longer fire seasons because of climate change . In 2014 , the Bureau of Meteorology released a report on the state of Australia 's climate that highlighted several key points , including the significant increase in Australia 's temperatures ( particularly night-time temperatures ) and the increasing frequency of bush fires , droughts and floods , which have all been linked to climate change . Since the beginning of the 20th century Australia has experienced an increase of nearly 1 ° C in average annual temperatures , with warming occurring at twice the rate over the past 50 years than in the previous 50 years . Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the impacts of climate change in Australia . Rainfall in southwestern Australia has decreased by 10 -- 20 % since the 1970s , while southeastern Australia has also experienced a moderate decline since the 1990s . Rainfall patterns are expected to be problematic , as rain has become heavier and infrequent , as well as more common in summer rather than in winter , with little or no uptrend in rainfall in the Western Plateau and the Central Lowlands of Australia . Water sources in the southeastern areas of Australia have depleted due to increasing population in urban areas ( rising demand ) coupled with climate change factors such as persistent prolonged drought ( diminishing supply ) . At the same time , Australia continues to have the highest per capita greenhouse gas emissions . Temperatures in Australia have also risen dramatically since 1910 and nights have become warmer . A carbon tax was introduced in 2011 by the Gillard government in an effort to reduce the impact of climate change and despite some criticism , it successfully reduced Australia 's carbon dioxide emissions , with coal generation down 11 % since 2008 -- 09 . The subsequent Australian Government , elected in 2013 under then Prime Minister Tony Abbott was criticised for being `` in complete denial about climate change '' . Furthermore , the Abbott government repealed the carbon tax on 17 July 2014 in a heavily criticised move . The renewable energy target ( RET ) , launched in 2001 , was heavily modified under Abbott 's government . However , under the government of Malcolm Turnbull , Australia attended the 2015 United Nations Climate Change Conference and adopted the Paris Agreement . This agreement includes a review of emission reduction targets every 5 years from 2020 . The federal government and all state governments ( New South Wales , Victoria , Queensland , South Australia , Western Australia , Tasmania , Northern Territory and the Australian Capital Territory ) have explicitly recognised that climate change is being caused by greenhouse gas emissions , in conformity with the scientific opinion on climate change . Sectors of the population have campaigned against new coal mines and coal-fired power stations , reflecting concerns about the effects of global warming on Australia . The Garnaut Climate Change Review predicted that a net benefit to Australia may be derived by stabilising greenhouse gases in the atmosphere at 450ppm CO2 eq . The per-capita carbon footprint in Australia was rated 12th in the world by PNAS in 2011 , considerably large given the small population of the country .", "qid": "581", "docid": "Climate_change_in_Australia", "rank": 8, "score": 103221 }, { "content": "Title: 1976 United Kingdom heat wave Content: The 1976 United Kingdom heat wave led to the hottest summer average temperature in the UK since records began .

In all climates , whether they contain permafrost or not , the temperature in the lower levels of the soil will remain more stable than that at the surface , where the influence of the ambient temperature is greatest . This means that , over many years , the influence of cooling in winter and heating in summer ( in temperate climates ) will decrease as depth increases . If the winter temperature is below the freezing point of water , a frost front will form in the soil . This `` frost front '' is the boundary between frozen and unfrozen soil , and with the coming of spring and summer , the soil is thawed , always from the top down . If the heating during summer exceeds the cooling during winter , the soil will be completely thawed during the summer and there will be no permafrost . This occurs when the mean annual temperature is above 0 ° C ( 32 ° F ) , but also occurs when the mean annual temperature is slightly below 0 ° C on sites exposed to the sun with coarse-textured parent materials ( vegetation ) . When there is not sufficient heat to thaw the frozen soil completely , permafrost forms . The active layer in this environment consists of the top layers of soil which thaws during the summer , while the inactive layer refers to the soil below which is frozen year-round because the heat fails to penetrate .

It may lead to phenomena such as houses feeling cooler in the winter and warmer in the summer at the same temperature . For example , in a room in which air temperature is maintained at 22 ° Celsius at all times , but in which the inner surfaces of the house is estimated to be an average temperature of 10 ° Celsius in the winter or 25 ° Celsius in the summer , heat transfer from the surfaces to the individual will occur , resulting in a difference in the perceived temperature . We can observe and compare the rate of radiation heat transfer between a person and the surrounding surfaces if we first make a few simplifying assumptions : The heat exchange in the environment is in a `` steady state '' , meaning that there is a constant flow of heat either into or out of the house . The person is completely surrounded by the interior surfaces of the room . Heat transfer by convection is not considered . The walls , ceiling , and floor are all at the same temperature . For an average person , the outer surface area is 1.4 m ² , the surface temperature is 30 ° Celsius , and the emissivity is 0.95 . Emissivity is the ability of a surface to emit radiant energy compared to that of a black body at the same temperature . We will be using the following equation to find out how much heat is lost by a person standing in the same room in summertime as compared to the winter , at exactly the same thermostat reading temperature : Q ̇ = εσA_s ( T_s ^ 4-T_surr ^ 4 ) Where Q ̇ is the rate of heat loss ( W ) , ε is the emissivity ( or the ability of an objects surface to emit energy by radiation ) of a person , σ is the Stefan-Boltzmann constant ( 5.670 x 10 ^ ( -8 ) W/m2 ∙ K4 ) , As is the surface area of a person , Ts is the surface temperature of a person ( K ) , and Tsurr is the surface temperature of the walls , ceiling , and floor ( K ) . Please note that this equation is only valid for an object standing in a completely enclosed room , box , etc. .

Networks of such records are used to reconstruct past temperatures for regions : tree ring proxies have been used to reconstruct Northern Hemisphere extratropical temperatures ( within the tropics trees do not form rings ) but are confined to land areas and are scarce in the Southern Hemisphere which is largely ocean . Wider coverage is provided by multiproxy reconstructions , incorporating proxies such as lake sediments , ice cores and corals which are found in different regions , and using statistical methods to relate these sparser proxies to the greater numbers of tree ring records . The `` Composite Plus Scaling '' ( CPS ) method is widely used for large-scale multiproxy reconstructions of hemispheric or global average temperatures ; this is complemented by Climate Field Reconstruction ( CFR ) methods which show how climate patterns have developed over large spatial areas , making the reconstruction useful for investigating natural variability and long-term oscillations as well as for comparisons with patterns produced by climate models . During the 1,900 years before the 20th century , it is likely that the next warmest period was from 950 to 1100 , with peaks at different times in different regions . This has been called the Medieval Warm Period , and some evidence suggests widespread cooler conditions during a period around the 17th century known as the Little Ice Age . In the hockey stick controversy , contrarians have asserted that the Medieval Warm Period was warmer than at present , and have disputed the data and methods of climate reconstructions .", "qid": "581", "docid": "Temperature_record_of_the_past_1000_years", "rank": 54, "score": 84598 }, { "content": "Title: Climate of New York Content: The climate of New York state is generally humid continental , while the extreme southeastern portion of the state ( New York City area ) lies in the warm temperate climate zone .

Due to the lack of solar heating and very strong radiative cooling from carbon dioxide , the mesosphere is the coldest region on Earth with temperatures as low as -100 ° C ( -148 ° F or 173 K ) . The altitude of the mesopause for many years was assumed to be at around 85 km ( 53 mi . ) , but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km . ( 62 mi . ) Another feature is that the summer mesopause is cooler than the winter ( sometimes referred to as the mesopause anomaly ) . It is due to a summer-to-winter circulation giving rise to upwelling at the summer pole and downwelling at the winter pole . Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause . In the mesosphere the summer-to-winter circulation is due to gravity wave dissipation , which deposits momentum against the mean east-west flow , resulting in a small north-south circulation . In recent years the mesopause has also been the focus of studies on global climate change associated with increases in CO2 . Unlike the troposphere , where greenhouse gases result in the atmosphere heating up , increased CO2 in the mesosphere acts to cool the atmosphere due to increased radiative emission . This results in a measurable effect - the mesopause should become cooler with increased CO2 .

As Pakistan is located on a great landmass north of the Tropic of Cancer ( between latitudes 25 ° and 36 ° N ) , it has a continental type of climate characterized by extreme variations of temperature , both seasonally and daily . Very high altitudes modify the climate in the cold , snow-covered northern mountains ; temperatures on the Balochistan Plateau are somewhat higher . Along the coastal strip , the climate is modified by sea breezes . In the rest of the country , temperatures reach great heights in the summer ; the mean temperature during June is 38 ° F in the plains , the highest temperatures can exceed 47 ° C . In the summer , hot winds called Loo blow across the plains during the day . Trees shed their leaves to avoid loss of moisture . The dry , hot weather is broken occasionally by dust storms and thunderstorms that temporarily lower the temperature . Evenings are cool ; the diurnal variation in temperature may be as much as 11C to 17C . Winters are cold , with minimum mean temperatures in Punjab of about 4 ° C in January , and sub-zero temperatures in the far north and Balochistan . The monsoon and the Western Disturbance are the two main factors which alter the weather over Pakistan ; otherwise , Continental air prevails for rest of the year . Following are the main factors that influence the weather over Pakistan . Western Disturbances mostly occur during the winter months and cause light to moderate showers in southern parts of the country while moderate to heavy showers with heavy snowfall in the northern parts of the country . These westerly waves are robbed of most of the moisture by the time they reach Pakistan . Fog occurs during the winter season and remains for weeks in upper Sindh , central Khyber Pakhtunkhwa and Punjab . Southwest Monsoon occurs in summer from the month of June till September in almost whole Pakistan excluding western Balochistan , FATA , Chitral and Gilgit -- Baltistan . Monsoon rains bring much awaited relief from the scorching summer heat . These monsoon rains are quite heavy by nature and can cause significant flooding , even severe flooding if they interact with westerly waves in the upper parts of the country . Tropical Storms usually form during the summer months from late April till June and then from late September till November . They affect the coastal localities of the country . Dust storms occur during summer months with peak in May and June , They are locally known as Andhi . These dust storms are quite violent . Dust storms during the early summer indicates the arrival of the monsoons while dust storms in the autumn indicate the arrival of winter . Heat waves occur during May and June , especially in southern Punjab , central Balochistan and interior Sindh . Thunderstorms most commonly occur in northern Punjab , Khyber Pakhtunkhwa and Azad Kashmir . Continental air prevails during the period when there is no precipitation in the country .

The onset and duration of these seasons vary somewhat according to location . The climate in the capital city of Islamabad varies from an average daily low of 2 ° C in January to an average daily high of 38 ° C in June . Half of the annual rainfall occurs in July and August , averaging about 255 millimeters in each of those two months .

Rocket and radar measurements indicate that a partial reflection from a multitude of ion layers and constructive interference causes at least some of the PMSE . Generally PMSE exhibits dramatic variations in height and intensity as well as large variations in Doppler shift . PMSE exhibit strong signal power enhancements of scattering cross section at VHF radar frequencies in the range 50 MHz to 250 MHz , at times even to over 1 GHz , that occur in summer at high latitudes . The peak PMSE height is slightly below the summer mesopause temperature minimum at 88 km , and above the noctilucent cloud ( NLC ) and/or polar mesospheric cloud ( PMC ) layer at 83 -- 84 km . The usual instrument for observing PMSE is the a VHF Mesosphere-Stratosphere-Troposphere ( MST ) radar , although LIDARs and sounding rockets have also been used .

The average rainfall in Sindh is only 6 - per year . The region 's scarcity of rainfall is compensated by the inundation of the Indus twice a year , caused by the spring and summer melting of Himalayan snow and by rainfall in the monsoon season .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions . They were preserved so well by quick freezing , which is taken as evidence of a rapid onset of a global blizzard or similar event . Interspersed with the analytical parts of the book are a series of interlinked short fictional scenarios , written in italics , describing what might transpire today if a destabilization of the North Atlantic Current were to occur .

The adjective thermohaline derives from thermo - referring to temperature and referring to salt content , factors which together determine the density of sea water . Wind-driven surface currents ( such as the Gulf Stream ) travel polewards from the equatorial Atlantic Ocean , cooling en route , and eventually sinking at high latitudes ( forming North Atlantic Deep Water ) . This dense water then flows into the ocean basins . While the bulk of it upwells in the Southern Ocean , the oldest waters ( with a transit time of around 1000 years ) upwell in the North Pacific . Extensive mixing therefore takes place between the ocean basins , reducing differences between them and making the Earth 's oceans a global system .

The state of Alaska , on the northwestern corner of the North American continent , is largely subarctic climate , but with a subpolar oceanic climate in the southeast ( Alaska Panhandle ) , southwestern peninsula and Aleutian Islands . The primary drivers of weather in the contiguous United States are the seasonal change in the solar angle , the migration north/south of the subtropical highs , and the seasonal change in the position of the polar jet stream . In the Northern Hemisphere summer the Subtropical high pressure systems move northward and closer to the United States mainland . In the Atlantic Ocean , the `` Bermuda High '' creates a south-southwest flow of warm , humid air over the eastern , southern and central United States - resulting in warm to hot temperatures , high humidity and occasional thunderstorm activity . In the Pacific Ocean high pressure builds toward the California coast resulting in a northwesterly airflow creating the typical sunny , dry , and stable weather conditions along the West Coast . In the Northern Hemisphere winter , the subtropical highs retreat southward . The polar jet stream ( and associated conflict zone between cold , dry air masses from Canada and warm , moist air masses from the Gulf of Mexico ) drops further southward into the United States - bringing more precipitation and periods of disturbed weather , as well as colder or mild air masses . Areas in the southern US ( Florida , the Gulf Coast , the Desert Southwest , and southern California ) however , often have more stable weather , as the polar jet stream 's impact does not usually reach that far south . Weather systems , be they high-pressure systems ( anticyclones ) , low-pressure systems ( cyclones ) or fronts ( boundaries between air masses of differing temperature , humidity and most commonly , both ) are faster-moving and more intense in the winter/colder months than in the summer/warmer months , when the belt of lows and storms generally move into southern Canada . The Gulf of Alaska is the origination area of many storms that enter the United States . Such `` North Pacific lows '' enter the US through the Pacific Northwest , then move eastward across the northern Rocky Mountains , northern Great Plains , upper Midwest , Great Lakes and New England states . Across the central states from late fall to spring , `` Panhandle hook '' storms move from the central Rockies into the Oklahoma/Texas panhandle areas , then northeast toward the Great Lakes . They generate unusually large temperature contrasts , and often bring heavy Gulf moisture northward , resulting sometimes in cold conditions and possibly-heavy snow or ice north and west of the storm track , and warm conditions , heavy rains and potentially-severe thunderstorms south and east of the storm track - often simultaneously . Across the northern states in winter usually from Montana eastward , `` Alberta clipper '' storms track east and bring light to moderate snowfalls from the Great Lakes to New England , and often , windy and severe Arctic outbreaks behind them . When winter-season Canadian cold air masses drop unusually far southward , `` Gulf lows '' can develop in or near the Gulf of Mexico , then track eastward or northeastward across the Southern states , or nearby Gulf or South Atlantic waters . They often bring rain , but on rare occasions can bring ice to areas of the interior southern states . In the cold season ( generally November to March ) , most precipitation occurs in conjunction with organized low-pressure systems and associated fronts . In the summer , storms are much more localized , with short-duration thunderstorms common in many areas east of the 100th meridian . In the warm season , storm systems affecting a large area are less frequent , and weather conditions are more solar -LCB- sun -RCB- controlled , with the greatest chance for thunderstorm and severe weather activity during peak heating hours , mostly between 3 PM and 9 PM local time . From May to August especially , often-overnight mesoscale-convective-system ( MCS ) thunderstorm complexes , usually associated with frontal activity , can deliver significant to flooding rainfall amounts from the Dakotas/Nebraska eastward across Iowa/Minnesota to the Great Lakes states . From late summer into fall ( mostly August to October ) , tropical cyclones sometimes approach or cross the Gulf and Atlantic states , bringing high winds , heavy rainfall , and storm surges ( often topped with battering waves ) to coastal areas .", "qid": "582", "docid": "Climate_of_the_United_States", "rank": 7, "score": 140238 }, { "content": "Title: Migration of marine species in the Northern Atlantic Ocean Content: The world 's oceans are warming due to climate change .

The greenhouse effect is caused by greenhouse gases that absorb sunlight . Energy from the sun that reaches Earth is either retained or sent into space . Greenhouse gases in Earth 's atmosphere such as carbon dioxide , methane , and water vapor absorb energy which cause a blanketing effect that warms the earth .

The difference of density being the only driving force . If the differences of density are caused by heat , this force is called as `` thermal head '' or `` thermal driving head . '' A fluid system designed for natural circulation will have a heat source and a heat sink . Each of these is in contact with some of the fluid in the system , but not all of it . The heat source is positioned lower than the heat sink . Most materials that are fluid at common temperatures expand when they are heated , becoming less dense . Correspondingly , they become denser when they are cooled . At the heat source of a system of natural circulation , the heated fluid becomes lighter than the fluid surrounding it , and thus rises . At the heat sink , the nearby fluid becomes denser as it cools , and is drawn downward by gravity . Together , these effects create a flow of fluid from the heat source to the heat sink and back again . Systems of natural circulation include tornadoes and other weather systems , ocean currents , and household ventilation . Some solar water heaters use natural circulation . The Gulf Stream circulates as a result of the evaporation of water . In this process , the water increases in salinity and density . In the North Atlantic Ocean , the water becomes so dense that it begins to sink down . In a nuclear reactor , natural circulation can be a design criterion . It is achieved by reducing turbulence and friction in the fluid flow ( that is , minimizing head loss ) , and by providing a way to remove any inoperative pumps from the fluid path . Also , the reactor ( as the heat source ) must be physically lower than the steam generators or turbines ( the heat sink ) . In this way , natural circulation will ensure that the fluid will continue to flow as long as the reactor is hotter than the heat sink , even when power can not be supplied to the pumps . Notable examples are the S5G and S8G United States Naval reactors , which were designed to operate at a significant fraction of full power under natural circulation , quieting those propulsion plants . The S6G reactor can not operate at power under natural circulation , but can use it to maintain emergency cooling while shut down . By the nature of natural circulation , fluids do not typically move very fast , but this is not necessarily bad , as high flow rates are not essential to safe and effective reactor operation . In modern design nuclear reactors , flow reversal is almost impossible . All nuclear reactors , even ones designed to primarily use natural circulation as the main method of fluid circulation , have pumps that can circulate the fluid in the case that natural circulation is not sufficient .", "qid": "582", "docid": "Natural_circulation", "rank": 71, "score": 109792 }, { "content": "Title: Gulf of Guinea Content: The Gulf of Guinea is the northeasternmost part of the tropical Atlantic Ocean between Cape Lopez in Gabon , north and west to Cape Palmas in Liberia .

Precipitation is usually well distributed through the year . The definition of this climate regarding temperature is as follows : the mean temperature of the coldest month must be below − 3 ° C and there must be at least four months whose mean temperatures are at or above 10 ° C . Some climatologists prefer to use the 0 ° C isotherm as it is more commonly used . In addition , the location in question must not be semi-arid or arid . Humid continental climates tend to be found between latitudes 40 ° N and 60 ° N , within the central and northeastern portions of North America , Europe , and Asia . They are much less commonly found in the Southern Hemisphere due to the larger ocean area at that latitude and the consequent greater maritime moderation . In the Northern Hemisphere some of the humid continental climates , typically in Scandinavia , Nova Scotia , and Newfoundland are heavily maritime-influenced , with relatively cool summers and winters being just below the freezing mark . More extreme humid continental climates found in southern Siberia and the American Midwest combine hotter summer maxima and colder winters than the marine-based variety .

The water that is upwelled by the current merges with another upwelling system , creating one of the most productive ecosystems in the ocean . The Somali current is characterized by seasonal changes influenced by the Southwest monsoon and the Northeast Monsoon .

It generated the highest storm surge on record in Mobile , Alabama , wrought widespread havoc on shipping , and dropped torrential rainfall peaking at more than 2 ft. The second tropical cyclone , first hurricane , and first major hurricane -- Category 3 or stronger on the modern-day Saffir -- Simpson scale -- of the highly active 1916 Atlantic hurricane season , the system originated in the southwestern Caribbean Sea on June 28 and moved generally toward the north-northwest . Crossing the Yucatán Channel on July 3 as a strengthening hurricane and brushing Cuba with gusty winds , the cyclone reached its peak intensity with maximum sustained winds of 125 mph ( 195 km/h ) prior to making landfall near Pascagoula , Mississippi , at 20:00 UTC on July 5 . Over land , the hurricane rapidly weakened to a tropical storm , but then retained much of its remaining strength as it meandered across interior Mississippi and Alabama for several days , its northward progress suppressed by a sprawling high pressure area to the north . It weakened into a tropical depression on June 9 and dissipated late the next day over southern Tennessee . The United States Weather Bureau first took notice of the developing storm on July 2 , and tropical cyclone watches and warnings were posted for much of the central Gulf Coast on July 4 and 5 . Upon moving ashore , the cyclone produced sustained Category 3 winds over coastal Mississippi and Alabama , with the worst damage mainly confined to east of the storm 's center . An 11.6 ft storm surge in Mobile destroyed wharves and severely flooded the city 's business district , while many buildings were unroofed or otherwise damaged by the winds . Boats of all sizes in Mobile Bay were sunk or blown ashore , and despite efforts to prepare warehouses for the tidal flooding , $ 500,000 in merchandise was lost . Further east , Pensacola , Florida , endured several days of gale-force winds after the initial passage of the storm 's core ; though wind damage to homes , businesses , and trees was extensive , the worst damage resulted from storm tides along the immediate coast . Throughout the region , the hurricane severed telephone and telegraph communications . Numerous ships were lost in the Gulf of Mexico , some with their entire crews . As the storm slowly proceeded inland , days of downpours caused rivers to rise precipitously from Mississippi to Georgia , overflowing their banks for several miles in each direction ; the Chattahoochee River exceeded flood stage by 23.7 ft. In Alabama alone , 350,000 acres of farmland was submerged , leading to millions of dollars in crop damage . Railroads were flooded , washed out , or blocked by debris , and many sawmills and other industrial facilities were adversely affected . In addition , the hurricane 's outer bands spawned multiple tornadoes that each caused severe but localized damage to homes . More moderate rainfall in western North Carolina primed the French Broad River watershed for a catastrophic flooding event when another hurricane from the Atlantic coast moved over the same area just days later . The resulting disaster , the worst in Asheville , North Carolina 's history , killed 80 people . Including property damage , shipping losses , and crop failures , the Gulf Coast hurricane 's monetary toll was approximately $ 12.5 million , and at least 34 people died .", "qid": "583", "docid": "1916_Gulf_Coast_hurricane", "rank": 13, "score": 112103 }, { "content": "Title: Summer Content: Summer is the hottest of the four temperate seasons , falling between spring and autumn .

The third named storm of the 2015 North Indian Ocean cyclone season , it developed on 28 October off western India from the monsoon trough . Fueled by record warm water temperatures , the system quickly intensified and was named Chapala by the India Meteorological Department ( IMD ) . By 30 October , the storm developed an eye in the center of a well-defined circular area of deep convection . That day , the IMD estimated peak three-minute sustained winds of 215 km/h ( 130 mph ) , and the JTWC estimated one-minute winds of 240 km/h ( 150 mph ) ; only Cyclone Gonu in 2007 was stronger in the Arabian Sea . After peak intensity , Chapala skirted the Yemeni island of Socotra on 1 November . Drier air and increased wind shear weakened the cyclone , although it maintained much of its intensity upon entering the Gulf of Aden on 2 November , becoming the strongest known cyclone in that body of water . After bypassing northern Somalia , Chapala weakened further and turned to the west-northwest . Early on 3 November , the storm made landfall near Mukalla , Yemen , as a very severe cyclonic storm , making it the strongest storm on record to strike the nation . The storm dissipated the next day . The cyclone first affected Socotra , becoming the first hurricane-force storm there since 1922 . High winds and heavy rainfall resulted in an island-wide power outage , and severe damage was compounded by Cyclone Megh just days later . Chapala brushed the northern coast of Somalia , killing thousands of animals and wrecking 250 houses . One person drowned off the coast when a boat capsized amid the storm . Ahead of the cyclone 's final landfall , widespread evacuations occurred across southeastern Yemen , including in areas controlled by al-Qaeda , amid the country 's ongoing civil war . Heavy rainfall -- the equivalent to several years ' worth -- inundated coastal areas , which damaged or destroyed roads and hundreds of homes . Eight people died in Yemen , a low total credited to the evacuations , and another 65 were injured . After the storm and later Cyclone Megh , various countries , non-government organizations , and agencies within the United Nations provided monetary and material assistance to Yemen .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions . They were preserved so well by quick freezing , which is taken as evidence of a rapid onset of a global blizzard or similar event . Interspersed with the analytical parts of the book are a series of interlinked short fictional scenarios , written in italics , describing what might transpire today if a destabilization of the North Atlantic Current were to occur . The fictional accounts of `` current events '' as the meteorological situation deteriorates provided background and inspiration for the 2004 science fiction film The Day After Tomorrow .

Lows sometimes fall to or below 50 F , with an average 3 such occurrences annually , but very rarely 40 F ; from 1981 to 2010 , temperatures reached that level in only eight calendar years . Highs generally reach 70 F or higher , and fail to do so on only an average of 12 days annually . The wet season usually begins during the month of May and continues through mid-October . During this period , temperatures are in the mid 80s to low 90s ( 29 -- 35 ° C ) , accompanied by high humidity , though the heat is often relieved by afternoon thunderstorms or a sea breeze that develops off the Atlantic Ocean , which then allow lower temperatures , but conditions still remain very muggy .

Miami reports more thunderstorms than most US cities , with about eighty days per year having thunder reported . These storms are often strong , with frequent lightning and very heavy rain . Occasionally , they can be severe with damaging straight line winds and large hail . Tornadoes and waterspouts sometimes occur , although violent tornadoes of the type seen in other parts of the United States are rare in Florida .

The former highest official temperature on Earth , held for 90 years by ` Aziziya , Libya , was de-certified by the WMO ( World Meteorological Organization ) in January 2012 as the record for the world 's highest surface temperature ( this temperature of 57.8 ° C ( 136 ° F ) , registered on 13 September 1922 , is currently considered to have been a recorder 's error ) .

Exceptionally favorable environmental conditions fueled explosive intensification on October 22 . A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours -- a near-record pace . On October 23 , the hurricane achieved its record peak intensity with maximum sustained winds of 215 mph ( 345 km/h ) . This made it the most intense tropical cyclone on record in the Western Hemisphere , and the strongest globally in terms of 1-minute maximum sustained winds . Late on October 23 , dramatic weakening ensued and Patricia made landfall near Cuixmala , Jalisco , with winds of 150 mph ( 240 km/h ) . This made it the strongest landfalling hurricane on record along the Pacific coast of Mexico . Patricia continued to weaken extremely quickly , faster than it had intensified , as it interacted with the mountainous terrain of Mexico .

As Pakistan is located on a great landmass north of the Tropic of Cancer ( between latitudes 25 ° and 36 ° N ) , it has a continental type of climate characterized by extreme variations of temperature , both seasonally and daily . Very high altitudes modify the climate in the cold , snow-covered northern mountains ; temperatures on the Balochistan Plateau are somewhat higher . Along the coastal strip , the climate is modified by sea breezes . In the rest of the country , temperatures reach great heights in the summer ; the mean temperature during June is 38 ° F in the plains , the highest temperatures can exceed 47 ° C . In the summer , hot winds called Loo blow across the plains during the day . Trees shed their leaves to avoid loss of moisture . The dry , hot weather is broken occasionally by dust storms and thunderstorms that temporarily lower the temperature . Evenings are cool ; the diurnal variation in temperature may be as much as 11C to 17C . Winters are cold , with minimum mean temperatures in Punjab of about 4 ° C in January , and sub-zero temperatures in the far north and Balochistan . The monsoon and the Western Disturbance are the two main factors which alter the weather over Pakistan ; otherwise , Continental air prevails for rest of the year . Following are the main factors that influence the weather over Pakistan . Western Disturbances mostly occur during the winter months and cause light to moderate showers in southern parts of the country while moderate to heavy showers with heavy snowfall in the northern parts of the country . These westerly waves are robbed of most of the moisture by the time they reach Pakistan . Fog occurs during the winter season and remains for weeks in upper Sindh , central Khyber Pakhtunkhwa and Punjab . Southwest Monsoon occurs in summer from the month of June till September in almost whole Pakistan excluding western Balochistan , FATA , Chitral and Gilgit -- Baltistan . Monsoon rains bring much awaited relief from the scorching summer heat . These monsoon rains are quite heavy by nature and can cause significant flooding , even severe flooding if they interact with westerly waves in the upper parts of the country . Tropical Storms usually form during the summer months from late April till June and then from late September till November . They affect the coastal localities of the country . Dust storms occur during summer months with peak in May and June , They are locally known as Andhi . These dust storms are quite violent . Dust storms during the early summer indicates the arrival of the monsoons while dust storms in the autumn indicate the arrival of winter . Heat waves occur during May and June , especially in southern Punjab , central Balochistan and interior Sindh . Thunderstorms most commonly occur in northern Punjab , Khyber Pakhtunkhwa and Azad Kashmir . Continental air prevails during the period when there is no precipitation in the country . Pakistan has four seasons : a cool , dry winter from December through February ; a hot , dry spring from March through May ; the summer rainy season , or southwest monsoon period , from June through September ; and the retreating monsoon period of October and November . The onset and duration of these seasons vary somewhat according to location . The climate in the capital city of Islamabad varies from an average daily low of 2 ° C in January to an average daily high of 38 ° C in June . Half of the annual rainfall occurs in July and August , averaging about 255 millimeters in each of those two months . The remainder of the year has significantly less rain , amounting to about fifty millimeters per month . Hailstorms are common in the spring . Pakistan 's largest city , Karachi , which is also the country 's industrial center , is more humid than Islamabad but gets less rain . Only July and August average more than twenty-five millimeters of rain in the Karachi area ; the remaining months are exceedingly dry .

Originating from a sprawling disturbance near the Gulf of Tehuantepec in mid-October 2015 , Patricia was first classified a tropical depression on October 20 . Initial development was slow , with only modest strengthening within the first day of its classification . The system later became a tropical storm and was named Patricia , the twenty-fourth named storm of the annual hurricane season . Exceptionally favorable environmental conditions fueled explosive intensification on October 22 . A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours -- a near-record pace . The magnitude of intensification was poorly forecast and both forecast models and meteorologists suffered from record-high prediction errors . On October 23 , two Hurricane Hunter missions both revealed the storm to have acquired maximum sustained winds of 205 mph ( 335 km/h ) and a pressure of 879 mbar ( hPa ; 25.96 inHg ) . Since the peak intensity was assessed to have occurred between the missions , the National Hurricane Center ultimately estimated Patricia to have acquired winds of 215 mph ( 345 km/h ) and pressure of 872 mbar ( hPa ; 25.75 inHg ) .

Very warm air pushed northward west of the Great Lakes region , and subsequently spread eastward . The intense poleward air mass movement was propelled by an unusually intense low level southerly jet that stretched from Louisiana to western Wisconsin . Once this warm surge inundated the area , a remarkably prolonged period of record setting temperatures ensued . NOAA 's National Climate Data Center reported that over 7,000 daily record high temperatures were tied or broken from 1 March through 27 March . In some places the temperature exceeded 86 ° F ( 30 ° C ) . For instance , in Grand Rapids , Michigan , the highest temperature recorded was 87 ° F on March 21 ; in Chicago a high of 87 ° F was also recorded on that same day . Records were broken in unusual ways . Chicago , for example , saw temperatures above 80 ° F every day between March 14 -- 18 , breaking records on all five days . Chicago would go on to record eight days at or above 80 ° F during the month , with many suburban areas recording an additional day in the 80s on March 19 ( that day , the city only tied its record high of 78 ° F ) . In context , the National Weather Service 's Chicago branch noted that Chicago typically averages only one day in the 80 's in April . And only once in 140 years of weather observations has April produced as many 80 ° F days as this March . In Traverse City , Michigan one day began with a low temperature ( 67 ° F ) higher than the previous record high for the day . Temperature records across much of southern Canada also were shattered . Some of the most impressive readings came from Nova Scotia on March 22 , when the mercury climbed to 30.0 C at a climate station in Lake Major , making it the highest March temperature recorded in Nova Scotia , and the third highest March temperature recorded in Canada . That same day , the temperature hit 29.2 C at Western Head , Nova Scotia . The heat reached as far east as Cape Breton Island , with the temperature climbing to 24.0 C at Sydney , Nova Scotia on March 22 , a place historically surrounded by ice-jammed waters , frigid winds , and snow in March . The week of March 18 also set record temperatures in Manitoba and much of Ontario as well as into the Maritime Provinces . Non-severe thunderstorms were reported on the evening hours of March 21 , through to the early morning hours March 22 into northern Ontario . In addition , NCEP/NCAR Reanalysis data show that the atmospheric pattern was so persistent that much of the Midwest and Northeast , and up into Ontario , had temperature departures over periods of several days to a week or more of magnitudes which would be unusual even for a single day . Averaged over the seven-day period from March 16 to March 22 inclusive , nearly the entire area of the Midwest and Northeast U.S. and most of Ontario and Quebec had temperatures 10 ° C ( 18 ° F ) or more above the 1981-2010 average . Even more dramatically , most of Iowa and Minnesota , all of Wisconsin and Michigan , and most of southeastern Ontario had seven-day mean temperatures more than 15 ° C ( 27 ° F ) above the climatological average for the same period . An 84 ° F high at Madison , WI in early March was 43 ° F above average and followed an overnight low of 60 ° F , 35 degrees above normal the daily high being more than seven standard deviations above the mean . The absolute temperature and departure statistically would be equivalent to a mid-July high at that station in excess of 125 ° F or more ; the highest temperature recorded there was 107 ° at least once during the heat waves of the middle 1930s . This mild warm spell brought out spring peepers in northern Ontario on 23 March , which are usually not heard until mid-to-late April , or sometimes early May .

In principle , thermometers made of different material ( e.g. , coloured alcohol thermometers ) might be expected to give different intermediate readings due to different expansion properties ; in practice the substances used are chosen to have reasonably linear expansion characteristics as a function of true thermodynamic temperature , and so give similar results .

Also , like Venus and the Moon , the planet displays the complete range of phases as it moves around its orbit relative to Earth .

The mercury runs down into a smaller bulb at the other end of the capillary , which is graduated to read temperature . A 360 ° turn in a locally widened portion of the capillary serves as a trap to prevent further addition of mercury if the thermometer is warmed and the mercury expands past the break-off point .

It is still used for barometric pressure in weather reports , refrigeration and aviation in the United States . It is the pressure exerted by a column of mercury of 1 in in height at the standard acceleration of gravity . Conversion to metric units depends on the temperature of mercury , and hence its density ; typical conversion factors are : Aircraft altimeters measure the relative pressure difference between the lower ambient pressure at altitude and a calibrated reading on the ground . Within the United States and Canada , these readings are provided in inches of mercury . Ground readings vary with weather and along the route of the aircraft as it travels , so current readings are relayed periodically by air traffic control . Aircraft operating at higher altitudes ( at or above what is called the transition altitude , which varies by country ) set their barometric altimeters to a standard pressure of 29.92 inHg ( 1 atm = 29.92 inHg ) or 1013.25 hPa ( 1 hPa = 1 mbar ) regardless of the actual sea level pressure . The resulting altimeter readings are known as flight levels . Piston engine aircraft with constant-speed propellers also use inches of mercury to measure manifold pressure , which is indicative of engine power produced . In automobile racing , particularly United States Auto Club and Champ Car Indy car racing , inches of mercury was the unit used to measure turbocharger inlet pressure . However , the inch of mercury is still used today in car performance modification to measure the amount of vacuum within the engine 's intake manifold . This can be seen on boost/vacuum gauges . In air conditioning and refrigeration , inHg is often used to describe `` inches of mercury vacuum '' , or pressures below ambient atmospheric pressure , for recovery of refrigerants from air conditioning and refrigeration systems , as well as for leak testing of systems while under a vacuum , and for dehydration of refrigeration systems . The low-side gauge in a refrigeration gauge manifold indicates pressures below ambient in `` inches of mercury vacuum '' ( inHg ) , down to a 30 inHg vacuum . Inches of mercury is also used in automotive cooling system vacuum test and fill tools . A technician will use this tool to remove air from modern automotive cooling systems , test the systems ability to hold vacuum and subsequently refill using the vacuum as suction for the new coolant .

This mainly includes the planets Mercury and Venus . A solar eclipse is also a solar transit of the Moon , but technically only if it does not cover the entire disc of the Sun ( an annular eclipse ) , as `` transit '' counts only objects that are smaller than what they are passing in front of . Solar transit is only one of several types of astronomical transit . Solar transit ( or a solar outage , sometimes solar fade , sun outage , or sun fade ) also occurs to communications satellites , which pass in front of the Sun for several minutes each day for several days straight for a period in the months around the equinoxes , the exact dates depending on where the satellite is in the sky relative to its earth station . Because the Sun also produces a great deal of microwave radiation in addition to sunlight , it overwhelms the microwave radio signals coming from the satellite 's transponders . This enormous electromagnetic interference causes interruptions in fixed satellite services that use satellite dishes , including TV networks and radio networks , as well as VSAT and DBS . Only downlinks from the satellite are affected , uplinks from the Earth are normally not , as the planet `` shades '' the Earth station when viewed from the satellite . Satellites in geosynchronous orbit are irregularly affected based on their inclination . Reception from satellites in other orbits are frequently but only momentarily affected by this , and by their nature the same signal is usually repeated or relayed on another satellite , if a tracking dish is used at all . Satellite radio and other services like GPS are not affected , as they use no receiving dish , and therefore do not concentrate the interference . ( GPS and certain satellite radio systems use non-geosynchronous satellites . ) Solar transit begins with only a brief degradation in signal quality for a few moments . At the same time each day , for the next several days , it gets longer and gets worse , until finally gradually improving after several more days . For digital satellite services , the cliff effect will eliminate reception entirely at a given threshold . Reception is typically lost for only a few minutes on the worst day , but the beam width of the dish can affect this . Signal strength also affects this , as does the bandwidth of the signal . If the power is concentrated into a narrower band , there is a higher signal-to-noise ratio . If the same signal is spread wider , the receiver also gets a wider swath of noise , degrading reception . The exact days and times of solar transit outages , for each satellite and for each receiving point ( Earth station ) on the Earth , are available at various websites . For broadcast networks , the network feed must be pre-recorded , replaced with local programming , fed via another satellite in a different orbital position , or fed via another method entirely during these times . In the Northern Hemisphere , solar transit is usually in early March and October . In the Southern Hemisphere , solar transit is usually in early September and April . The time of day varies mainly with the longitude of the satellite and receiving station , while the exact days vary mainly with the station 's latitude . Stations along the equator will experience solar transit right at the equinoxes , as that is where geostationary satellites are located directly over .

A thermometer has two important elements : ( 1 ) a temperature sensor ( e.g. the bulb of a mercury-in-glass thermometer ) in which some physical change occurs with temperature , and ( 2 ) some means of converting this physical change into a numerical value ( e.g. the visible scale that is marked on a mercury-in-glass thermometer ) . Thermometers are widely used in industry to control and regulate processes , in the study of weather , in medicine , and in scientific research . There are various principles by which different thermometers operate . They include the thermal expansion of solids or liquids with temperature , and the change in pressure of a gas on heating or cooling . Radiation-type thermometers measure the infrared energy emitted by an object , allowing measurement of temperature without contact . Most metals are good conductors of heat and they are solids at room temperature . Mercury is the only one in liquid state at room temperature , and has high coefficient of expansion . Hence , the slightest change in temperature is notable when it 's used in a thermometer . This is the reason behind mercury and alcohol being used in thermometer . Some of the principles of the thermometer were known to Greek philosophers of two thousand years ago .

Unlike the mercury-in-glass thermometer , the contents of an alcohol thermometer are less toxic and will evaporate away fairly quickly . The ethanol version is the most widely used due to the low cost and relatively low hazard posed by the liquid in case of breakage . An organic liquid is contained in a glass bulb which is connected to a capillary of the same glass and the end is sealed with an expansion bulb . The space above the liquid is a mixture of nitrogen and the vapor of the liquid . For the working temperature range , the meniscus or interface between the liquid is within the capillary . With increasing temperature , the volume of liquid expands and the meniscus moves up the capillary . The position of the meniscus shows the temperature against an inscribed scale . The liquid used can be pure ethanol , toluene , kerosene or Isoamyl acetate , depending on manufacturer and working temperature range . Since these are transparent , the liquid is made more visible by the addition of a red or blue dye . One half of the glass containing the capillary is usually enamelled white or yellow to give a background for reading the scale . The range of usefulness of the thermometer is set by the boiling point of the liquid used .

Ethanol-filled thermometers are used in preference to mercury for meteorological measurements of minimum temperatures and can be used down to − 70 ° C ( -94 ° F ) .

They are a system of linear hills and valleys that extend more than 1000 km to the northeast from the mountainous rim of Caloris Basin in the Shakespeare quadrangle ( H-3 ) . The range consists of numerous rectilinear massifs 1 to 2 km high and about 10 to 50 km long , mostly elongated radially from the center of the basin and separated by hackly-floored , radial troughs and gouge-like structures . The surfaces of the massifs are hackly . They are best developed along the inner edge of the basin where steep inward-facing scarps are common , grading outward into smaller massifs and blocks . The range marks the crest of most prominent ring structure around Caloris . The type area is the region near 18 ° , 184.5 ° ( FDS 229 ) .

Due to the lack of solar heating and very strong radiative cooling from carbon dioxide , the mesosphere is the coldest region on Earth with temperatures as low as -100 ° C ( -148 ° F or 173 K ) . The altitude of the mesopause for many years was assumed to be at around 85 km ( 53 mi . ) , but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km . ( 62 mi . ) Another feature is that the summer mesopause is cooler than the winter ( sometimes referred to as the mesopause anomaly ) . It is due to a summer-to-winter circulation giving rise to upwelling at the summer pole and downwelling at the winter pole . Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause . In the mesosphere the summer-to-winter circulation is due to gravity wave dissipation , which deposits momentum against the mean east-west flow , resulting in a small north-south circulation . In recent years the mesopause has also been the focus of studies on global climate change associated with increases in CO2 . Unlike the troposphere , where greenhouse gases result in the atmosphere heating up , increased CO2 in the mesosphere acts to cool the atmosphere due to increased radiative emission . This results in a measurable effect - the mesopause should become cooler with increased CO2 .

The Mercury spacecraft was unmanned and carried no launch escape system . The mission was to conduct a suborbital test flight and reentry of the spacecraft . The capsule had live posigrade separation rockets , but dummy retrorockets . Several other systems were missing including the cabin pressurization system and the astronaut couch . The ASIS abort system was flown for the first time on MA-1 in open-loop mode , meaning that the booster portion was present , but not the capsule portion . The Atlas rocket suffered a structural failure 58 seconds after launch . The vehicle at that time was at approximately an altitude of 30,000 feet ( 9.1 km ) and 11,000 feet ( 3.4 km ) down range when it was passing through Max Q and all telemetry signals suddenly ceased . Because the day was rainy and overcast with thick clouds , the booster had been out of sight from T +26 seconds and it was impossible to see what happened . A number of Mercury engineers had voiced their objection to launching on July 29 because of the weather precluding visual coverage of the flight . Some observers claim to have heard an explosion , but this could not be verified . The capsule continued transmitting until it impacted the ocean , approximately 6 miles downrange . Subsequent salvage attempts dredged it and the Atlas 's booster engines and LOX vent valve from the ocean floor . The booster engines showed no sign of damage except some deformation from impact with the ocean , but the vent valve and a still-attached segment of piping had noticeable fatigue cracks . Telemetry indicated that the Atlas functioned normally up to T +58 seconds and there was no sign of any problems up to that point , when a severe axial disturbance was detected . Approximately one second later , the pressure difference between the RP-1 and LOX tanks dropped to zero followed by loss of engine thrust and telemetry and the appearance of multiple objects on radar . Capsule data indicated violent movements following loss of booster telemetry , but the Mercury otherwise continued functioning normally until impact with the ocean at around 220 seconds after launch . The automatic abort system appeared to have functioned correctly and issued a shutdown command to the Atlas 's engines the moment that it detected an abnormal situation . The parachute system did not deploy because the abort had taken place too early in the launch . Unlike R&D Atlas D missiles , Atlas 50D was not carrying a large compliment of telemetry probes ; only 50 measurements were taken on this flight . The Atlas had appeared to be on a steady flight path when telemetry was lost at T +60 seconds , but the last 1.2 seconds of telemetry data was questionable due to open circuits in the booster following the disturbance . The capsule gyroscope data suggested that the stack had pitched over as much as 10 ° . There had been two separate disturbances . The first one , at T +58.5 seconds , had caused the instant loss of telemetry measurements in the forward part of the booster . The second disturbance occurred at T +59.4 seconds , following the ASIS-generated engine cutoff . The propulsion system did not appear to be affected by the initial event . The initial suspicion was that the fiberglass fairing placed on top of the capsule to sit in place of the absent LES had broken loose and punctured the Atlas 's LOX tank . NASA 's Owen Maynard , who was involved in Mercury systems engineering , led the recovery of the MA-1 capsule from the sea-floor ( in which he performed a 30-foot free-dive to find one particular missing component of the capsule ) . He stated in an oral history interview that his post-flight calculations showed the skin of the launch vehicle just below the spacecraft would have buckled due to the combined drag , acceleration , and bending loads which exceeded the resisting tensile stress in the skin provided by internal pressure . Maynard recalled that `` The problem of mating the Mercury capsule to the Atlas was far from being properly resolved at the time of MA-1 . '' Based on that finding , the NASA specified that future Mercury-Atlas launch vehicles add doublers to the skin structure in that area , and that future launch trajectories be shallowed to reduce pitch angle rate , to reduce the bending stress on the launch vehicle . In fact , Atlas 50D already had slightly thicker skin than Big Joe 's booster ( Atlas 10D ) but only on the RP-1 tank while the LOX tank still had the standard thin-gauge Atlas ICBM skin . This failure mode did not recur on those subsequent launches . There were also suspicions that the lack of a launch escape system had negatively affected the booster 's aerodynamic profile . Convair engineers had argued that including the LES was necessary both from an aerodynamic standpoint and for data-gathering purposes , but Mercury program officials ultimately ruled against it . The capsule reached an apogee of 13 km and flew 9.6 km downrange . The flight lasted 3 minutes and 18 seconds . Capsule weight 1,154 kg . Serial numbers : Atlas 50-D , Mercury spacecraft # 4 .

Each weed or insect , is based on studies of how many warm days they need to emerge so each month a total of 50 degree days are totaled and compared to how many are needed for each . Temperature controls the developmental rate of many organisms . Plants and invertebrate animals , including insects and nematodes , require a certain amount of heat to develop from one point in their life cycles to another . This measure of accumulated heat is known as physiological time . Theoretically , physiological time provides a common reference for the development of organisms . The amount of heat required to complete a given organism 's development does not vary -- the combination of temperature ( between thresholds ) and time will always be the same . Physiological time is often expressed and approximated in units called degree-days ( ° D ) .

Colloquially , some refer to these organisms as `` cold blooded '' though such a term is not technically correct , as the blood temperature of the organism varies with ambient environmental temperature . Some of these animals live in environments where temperatures are practically constant , as is typical of regions of the abyssal ocean .

The degree Celsius ( ° C ) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval , a difference between two temperatures or an uncertainty . Before being renamed to honour Anders Celsius in 1948 , the unit was called centigrade , from the Latin centum , which means 100 , and gradus , which means steps . The current scale is based on 0 ° for the freezing point of water and 100 ° for the boiling point of water at 1 atm pressure following a change introduced by Jean-Pierre Christin to reverse the Celsius thermometer scale ( from water boiling at 0 degrees and ice melting at 100 degrees ) . This scale is widely taught in schools today . By international agreement the unit `` degree Celsius '' and the Celsius scale are currently defined by two different temperatures : absolute zero , and the triple point of Vienna Standard Mean Ocean Water ( VSMOW ) , a specially purified water . This definition also precisely relates the Celsius scale to the Kelvin scale , which defines the SI base unit of thermodynamic temperature with symbol K.

IFS is developed and maintained by the European Centre for Medium-Range Weather Forecasts ( ECMWF ) based in Reading , England . Because of its source , it is often known as the `` ECMWF '' or the `` European model '' in North America , to distinguish it from the American Global Forecast System ( GFS ) . It is one of the predominant synoptic-scale medium-range models in general use worldwide ; its most prominent rivals in the 6 -- 10 day medium range include the GFS and the Canadian Global Environmental Multiscale Model ( GEM and GDPS ) . The IFS is a global model that runs every twelve hours . Its output runs out to fifteen days in one-day intervals ( although output is only made available to most members of the public out to 7 to 10 days , depending on the variable ) . The operational model runs both in a deterministic forecast mode and as a 51-member ensemble . The current deterministic mode has a horizontal resolution of 16 km while the ensemble prediction systems have resolutions of 32 and 64 km , and 137 layers in the vertical resolution in the deterministic compared to 91 layers in the ensemble ; both modes ' vertical layers follow terrain at low levels . The IFS , like the GFS , uses spectral representation rather than a grid-based system . Because the IFS only offers output on a day-by-day interval , each individual ECMWF member country typically runs its own synoptic-scale forecast for the shorter ranges of 5 days or less , separate from the IFS , with smaller time intervals ( examples include the French ARPEGE , British Unified Model and German GME/ICON ) . In contrast to the GEM/GDPS ( which is copyrighted but freely licensed ) and the GFS ( which is public domain ) , the ECMWF 's proprietary data and forecasts are heavily restricted and require a licence for most output .

Weather forecasting represents a service in which probability forecasts are sometimes published for public consumption , although it may also be used by weather forecasters as the basis of a simpler type of forecast .

The pre-race odds published for a horse race can be considered to correspond to a summary of bettors ' opinions about the likely outcome of a race , although this needs to be tempered with caution as bookmakers ' profits needs to be taken into account .

It may lead to phenomena such as houses feeling cooler in the winter and warmer in the summer at the same temperature . For example , in a room in which air temperature is maintained at 22 ° Celsius at all times , but in which the inner surfaces of the house is estimated to be an average temperature of 10 ° Celsius in the winter or 25 ° Celsius in the summer , heat transfer from the surfaces to the individual will occur , resulting in a difference in the perceived temperature . We can observe and compare the rate of radiation heat transfer between a person and the surrounding surfaces if we first make a few simplifying assumptions : The heat exchange in the environment is in a `` steady state '' , meaning that there is a constant flow of heat either into or out of the house . The person is completely surrounded by the interior surfaces of the room . Heat transfer by convection is not considered . The walls , ceiling , and floor are all at the same temperature . For an average person , the outer surface area is 1.4 m ² , the surface temperature is 30 ° Celsius , and the emissivity is 0.95 . Emissivity is the ability of a surface to emit radiant energy compared to that of a black body at the same temperature . We will be using the following equation to find out how much heat is lost by a person standing in the same room in summertime as compared to the winter , at exactly the same thermostat reading temperature : Q ̇ = εσA_s ( T_s ^ 4-T_surr ^ 4 ) Where Q ̇ is the rate of heat loss ( W ) , ε is the emissivity ( or the ability of an objects surface to emit energy by radiation ) of a person , σ is the Stefan-Boltzmann constant ( 5.670 x 10 ^ ( -8 ) W/m2 ∙ K4 ) , As is the surface area of a person , Ts is the surface temperature of a person ( K ) , and Tsurr is the surface temperature of the walls , ceiling , and floor ( K ) .

The number of independent ways by which a dynamic system can move , without violating any constraint imposed on it , is called number of degrees of freedom . In other words , the number of degrees of freedom can be defined as the minimum number of independent coordinates that can specify the position of the system completely . Estimates of statistical parameters can be based upon different amounts of information or data . The number of independent pieces of information that go into the estimate of a parameter are called the degrees of freedom . In general , the degrees of freedom of an estimate of a parameter are equal to the number of independent scores that go into the estimate minus the number of parameters used as intermediate steps in the estimation of the parameter itself ( e.g. the sample variance has N − 1 degrees of freedom , since it is computed from N random scores minus the only 1 parameter estimated as intermediate step , which is the sample mean ) . Mathematically , degrees of freedom is the number of dimensions of the domain of a random vector , or essentially the number of `` free '' components ( how many components need to be known before the vector is fully determined ) . The term is most often used in the context of linear models ( linear regression , analysis of variance ) , where certain random vectors are constrained to lie in linear subspaces , and the number of degrees of freedom is the dimension of the subspace . The degrees of freedom are also commonly associated with the squared lengths ( or `` sum of squares '' of the coordinates ) of such vectors , and the parameters of chi-squared and other distributions that arise in associated statistical testing problems . While introductory textbooks may introduce degrees of freedom as distribution parameters or through hypothesis testing , it is the underlying geometry that defines degrees of freedom , and is critical to a proper understanding of the concept .

It is caused by the fungus Pithomyces chartarum that under favorable conditions can rapidly disseminate in pastures . The fungus requires warm humid weather with night time temperatures of over 13 ° C ( 55 ° F ) for several days , and litter at the bottom of the sward . Pithomyces chartarum occurs worldwide but is a problem predominantly where farm animals are intensively grazed , especially in New Zealand . The spores of the fungus release the mycotoxin sporidesmin in the gastrointestinal tract , causing a blockage in the bile ducts that leads to injury of the liver . Bile , chlorophyll and other waste products consequently build up in the bloodstream causing photo sensitivity of the skin especially that exposed to direct sunlight . This in turn causes severe skin irritation that the animal attempts to relieve by rubbing its head against available objects , resulting in peeling of the skin . The large family of fungi that produce mycotoxins , of which sporidesmin is one , live mainly on ryegrasses and can cause significant problems in grazing animals . Sporidesmin can lower an animals immunity and affect total production in farm animals , and , when taken in larger quantities , can result in death . The clinical symptoms of FE are distressing : restlessness , frequent urination , shaking , persistent rubbing of the head against objects ( e.g. fences , trees etc. ) , drooping and reddened ears , swollen eyes , and avoidance of sunlight by seeking shade .

Most escapements are capable of being stopped by a sudden movement but the detent escapement gives an impulse to the balance only when it is moving in one direction .

Therefore , climate sensitivity depends on the initial climate state , but potentially can be accurately inferred from precise palaeoclimate data . Slow climate feedbacks , especially changes of ice sheet size and atmospheric CO2 , amplify the total Earth system sensitivity by an amount that depends on the time scale considered . Although climate sensitivity is usually used in the context of radiative forcing by carbon dioxide ( CO2 ) , it is thought of as a general property of the climate system : the change in surface air temperature ( ΔTs ) following a unit change in radiative forcing ( RF ) , and thus is expressed in units of ° C / ( W/m2 ) . For this to be useful , the measure must be independent of the nature of the forcing ( e.g. from greenhouse gases or solar variation ) ; to first order this is indeed found to be so . The climate sensitivity specifically due to is often expressed as the temperature change in ° C associated with a doubling of the concentration of carbon dioxide in Earth 's atmosphere . For coupled atmosphere-ocean global climate models ( e.g. CMIP5 ) the climate sensitivity is an emergent property : it is not a model parameter , but rather a result of a combination of model physics and parameters . By contrast , simpler energy-balance models may have climate sensitivity as an explicit parameter . The terms represented in the equation relate radiative forcing ( RF ) to linear changes in global surface temperature change ( ΔTs ) via the climate sensitivity λ .

The Earth is much cooler and so radiates heat back away from itself at much longer wavelengths , mostly in the infrared range . The idealized greenhouse model is based on the fact that certain gases in the Earth 's atmosphere , including carbon dioxide and water vapour , are transparent to the high-frequency , high-energy solar radiation , but are much more opaque to the lower frequency infrared radiation leaving the surface of the earth . Thus heat is easily let in , but is partially trapped by these gases as it tries to leave . Rather than get hotter and hotter , Kirchhoff 's law of thermal radiation says that the gases of the atmosphere also have to re-emit the infrared energy that they absorb , and they do so , also at long infrared wavelengths , both upwards into space as well as downwards back towards the Earth 's surface . In the long-term , thermal equilibrium is reached when all the heat energy arriving on the planet is leaving again at the same rate . In this idealized model , the greenhouse gases cause the surface of the planet to be warmer than it would be without them , in order for the required amount of heat energy finally to be radiated out into space from the top of the atmosphere . The greenhouse effect can be illustrated with an idealized planet . This is a common `` textbook model '' : the planet will have a constant surface temperature Ts and an atmosphere with constant temperature Ta . For diagrammatic clarity , a gap can be depicted between the atmosphere and the surface . Alternatively , Ts could be interpreted as a temperature representative of the surface and the lower atmosphere , and Ta could be interpreted as the temperature of the upper atmosphere . In order to justify that Ta and Ts remain constant over the planet , strong ocean and atmospheric currents can be imagined to provide plentiful lateral mixing .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change .

The Global Climate Model at the core of EdGCM is GISS Model II . During the 1980s and early 1990s this GCM was one of NASA 's primary climate research tools . Results from the model have appeared in hundreds of scientific publications . The coarser resolution of the climate model in EdGCM ( 8 ° x 10 ° , latitude x longitude ) makes it inexpensive to run .

As approximately 97 % of publishing climate scientists support the consensus on anthropogenic climate change , this list represents a minority viewpoint . The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise . The balance of impacts of global warming become significantly negative at larger values of warming .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation .

The executive summary of the policymakers ' summary of the WG I report includes : We are certain of the following : there is a natural greenhouse effect ... ; emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases : CO2 , methane , CFCs and nitrous oxide . These increases will enhance the greenhouse effect , resulting on average in an additional warming of the Earth 's surface . The main greenhouse gas , water vapour , will increase in response to global warming and further enhance it . We calculate with confidence that : ... CO2 has been responsible for over half the enhanced greenhouse effect ; long-lived gases would require immediate reductions in emissions from human activities of over 60 % to stabilise their concentrations at today 's levels ...

Some scientific bodies have recommended specific policies to governments , and science can play a role in informing an effective response to climate change . Policy decisions , however , may require value judgements and so are not included in the scientific opinion . No scientific body of national or international standing maintains a formal opinion dissenting from any of these main points . The last national or international scientific body to drop dissent was the American Association of Petroleum Geologists , which in 2007 updated its statement to its current non-committal position .

Climate engineering is an umbrella term for measures that mainly fall into two types : carbon dioxide removal and solar radiation management . Carbon dioxide removal addresses the cause of global warming by removing one of the greenhouse gases ( carbon dioxide ) from the atmosphere . Solar radiation management attempts to offset effects of greenhouse gases by causing the Earth to absorb less solar radiation . Climate engineering approaches are sometimes viewed as additional potential options for limiting global warming , alongside mitigation and adaptation . There is substantial agreement among scientists that climate engineering can not substitute for climate change mitigation . Some approaches might be used as accompanying measures to sharp cuts in greenhouse gas emissions . Given that all types of measures for addressing climate change have economic , political , or physical limitations , some climate engineering approaches might eventually be used as part of an ensemble of measures . Research on costs , benefits , and various types of risks of most climate engineering approaches is at an early stage and their understanding needs to improve to judge their adequacy and feasibility . Almost all research into solar radiation management has consisted of computer modelling or laboratory tests , and an attempt to move to outdoor experimentation was controversial . Some carbon dioxide removal practices , such as planting of trees and bio-energy with carbon capture and storage projects , are underway . Their scalability to effectively affect global climate is , however , debated . Ocean iron fertilization has been given small-scale research trials , sparking substantial controversy . Most experts and major reports advise against relying on climate engineering techniques as a simple solution to global warming , in part due to the large uncertainties over effectiveness and side effects . However , most experts also argue that the risks of such interventions must be seen in the context of risks of dangerous global warming . Interventions at large scale may run a greater risk of disrupting natural systems resulting in a dilemma that those approaches that could prove highly ( cost - ) effective in addressing extreme climate risk , might themselves cause substantial risk . Some have suggested that the concept of engineering the climate presents a so-called `` moral hazard '' because it could reduce political and public pressure for emissions reduction , which could exacerbate overall climate risks ; others assert that the threat of climate engineering could spur emissions cuts .

In the scientific literature , there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases . No scientific body of national or international standing disagrees with this view , though a few organizations with members in extractive industries hold non-committal positions . Disputes over the key scientific facts of global warming are more prevalent in the media than in the scientific literature , where such issues are treated as resolved , and such disputes are more prevalent in the United States than globally . Political and popular debate concerning the existence and cause of climate change includes the reasons for the increase seen in the instrumental temperature record , whether the warming trend exceeds normal climatic variations , and whether human activities have contributed significantly to it . Scientists have resolved these questions decisively in favour of the view that the current warming trend exists and is ongoing , that human activity is the cause , and that it is without precedent in at least 2000 years . Public disputes that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases ( climate sensitivity ) , how global climate change will play out at local and regional scales , and what the consequences of global warming will be . Global warming remains an issue of widespread political debate , often split along party political lines , especially in the United States . Many of the issues that are settled within the scientific community , such as human responsibility for global warming , remain the subject of politically or economically motivated attempts to downplay , dismiss or deny them -- an ideological phenomenon categorised by academics and scientists as climate change denial . The sources of funding for those involved with climate science -- both supporting and opposing mainstream scientific positions -- have been questioned by both sides . There are debates about the best policy responses to the science , their cost-effectiveness and their urgency .

A National Emissions Inventory ( NEI ) measuring a country 's GHG emissions in a year is required by the UNFCCC to provide a benchmark for the country 's emission reductions , and subsequently to evaluate international climate policies such as the Kyoto protocol ( although the original has now expired , extensions have been agreed ) as well as regional climate policies such as the EU Emissions Trading Scheme ( ETS ) . There are two conflicting ways of measuring GHG emissions : production-based ( sometimes referred to as territorial-based ) or consumption-based . Production-based emissions take place `` within national territory and offshore areas over which the country has jurisdiction '' . Consumption-based emissions encompass those emissions from domestic final consumption and those caused by the production of its imports . This means the importing country takes responsibility for emissions related to production of the exporting country 's exports . By these definitions production-based emissions include exports but exclude imports and emissions embodied in international trade , whereas consumption-based emissions refer to the reverse ( Table 1 ) . Which technique is applied by policymakers is fundamental as each can generate a very different NEI . Different NEIs would result in a country 's choosing different optimal mitigation activities , the wrong choice based on wrong information being potentially damaging . The application of production-based emissions accounting is currently favoured in policy terms , although much of the literature favours consumption-based accounting .

The greenhouse effect is caused by greenhouse gases that absorb sunlight . Energy from the sun that reaches Earth is either retained or sent into space . Greenhouse gases in Earth 's atmosphere such as carbon dioxide , methane , and water vapor absorb energy which cause a blanketing effect that warms the earth . Aerosols such as black carbon also catalyze the warming effect as they are unreflective and absorb energy from the sun supplementing greenhouse gases in the warming effect . These combined factors are warming the Earth 's land as well as the oceans .

GHG emissions due to anthropogenic ( human ) activity are the dominant cause of observed global warming ( climate change ) since the mid-20th century .

This system is made up of earth 's water , ice , atmosphere , rocky crust , and all living things . Quantifying changes in these amounts is required to accurately model the Earth 's climate . Received radiation is unevenly distributed over the planet , because the Sun heats equatorial regions more than polar regions . Energy is absorbed by the atmosphere , hydrosphere , and lithosphere , and , in a process informally described as Earth 's heat engine , the solar heating is redistributed through evaporation of surface water , convection , rainfall , winds , and ocean circulation . When the incoming solar energy is balanced by an equal flow of heat to space , the Earth is said to be in radiative equilibrium and under that condition , global temperatures will be stable . Disturbances of Earth 's radiative equilibrium , such as an increase of greenhouse gases , will change global temperatures in response . However , Earth 's energy balance and heat fluxes depend on many factors , such as atmospheric composition ( mainly aerosols and greenhouse gases ) , the albedo ( reflectivity ) of surface properties , cloud cover and vegetation and land use patterns .

Colloquially , some refer to these organisms as `` cold blooded '' though such a term is not technically correct , as the blood temperature of the organism varies with ambient environmental temperature . Some of these animals live in environments where temperatures are practically constant , as is typical of regions of the abyssal ocean . In contrast , in places where temperature varies so widely as to limit the physiological activities of other kinds of ectotherms , many species habitually seek out external sources of heat or shelter from heat ; for example , many reptiles regulate their body temperature by bask in the sun , or seeking shade when necessary in addition to a whole host of other behavioral thermoregulation mechanisms . In contrast to ectotherms , endotherms rely largely , even predominantly , on heat from internal metabolic processes . In ectotherms , fluctuating ambient temperatures may affect the body temperature . Such variation in body temperature is called poikilothermy , though the concept is not widely satisfactory and the use of the term is declining .

P. fumarii is an unicellular organism from the domain Archaea living in the hydrothermal vents in black smokers along the Mid-Atlantic Ridge . These organisms can live at 106 ° C at a pH of 5.5 . In order to get energy from their environment these organisms are facultatively aerobic obligate chemolithoautotrophs , meaning these organisms build biomolecules by harvesting carbon dioxide ( CO2 ) from their environment by using hydrogen ( H2 ) as the primary electron donor and nitrate ( NO3 − ) as the primary electron acceptor . These organisms can even survive the autoclave , which is a machine designed to kill organisms through high temperature and pressure . Because hyperthermophiles live in such hot environments , they need to have DNA , membrane and enzyme modifications in order to withstand the intense thermal energy .

The degree Celsius ( ° C ) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval , a difference between two temperatures or an uncertainty . Before being renamed to honour Anders Celsius in 1948 , the unit was called centigrade , from the Latin centum , which means 100 , and gradus , which means steps .

This scale is widely taught in schools today . By international agreement the unit `` degree Celsius '' and the Celsius scale are currently defined by two different temperatures : absolute zero , and the triple point of Vienna Standard Mean Ocean Water ( VSMOW ) , a specially purified water .

When the boy gets the flu , a doctor is called in and recommends three different medicines and tells the boy 's father that his temperature is 102 degrees Fahrenheit ( 39 degrees Celsius ) . He is very quiet and depressed , finally asking when he will die ; he had thought that a 102 degree temperature was lethal because he heard in France ( where Celsius is used ) that one can not live with a temperature over 44 degrees .

The boy thinks he will die but the father thinks his son is only ill . The boy uses the word `` it '' to describe the process of dying . The father also uses the word `` it '' , but to describe that it is no problem for him to stay at home with his son . Since they only use the pronoun `` it '' neither of them knows what the other person is talking about . b ) The hunting scene The landscape is described as frozen because it 's a cold day . The father 's behaviour is also cold because he is shooting birds and killing them . The father 's inability to understand his son is symbolically expressed by the layer of ice separating him from nature ( he is helpless on the icy surface ) ; the same helplessness applies to his relationship to his son . c ) Interdependence between theme and point of view The theme focuses on the misunderstanding between father and son , which is disastrous for the son due to the lack of knowledge as far as the different scales are concerned . The failure in communication leads to the son ´ s being afraid of dying . This is why Hemingway chooses the first person narrator with a limited point of view . He is therefore confined to presenting mere observations and suppositions . `` The boy was evidently holding tight onto himself about something '' , which is only one example of the father ´ s suppositions . The father is only an observer of the scene without realizing the son ´ s fears . He remains detached and can not imagine and feel the son ´ s distress . An observer narrator is the best way of expressing this distance between the two .

The altitude of the mesopause for many years was assumed to be at around 85 km ( 53 mi . ) , but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km .

It is due to a summer-to-winter circulation giving rise to upwelling at the summer pole and downwelling at the winter pole . Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause . In the mesosphere the summer-to-winter circulation is due to gravity wave dissipation , which deposits momentum against the mean east-west flow , resulting in a small north-south circulation . In recent years the mesopause has also been the focus of studies on global climate change associated with increases in CO2 . Unlike the troposphere , where greenhouse gases result in the atmosphere heating up , increased CO2 in the mesosphere acts to cool the atmosphere due to increased radiative emission . This results in a measurable effect - the mesopause should become cooler with increased CO2 .

This system is made up of earth 's water , ice , atmosphere , rocky crust , and all living things . Quantifying changes in these amounts is required to accurately model the Earth 's climate . Received radiation is unevenly distributed over the planet , because the Sun heats equatorial regions more than polar regions . Energy is absorbed by the atmosphere , hydrosphere , and lithosphere , and , in a process informally described as Earth 's heat engine , the solar heating is redistributed through evaporation of surface water , convection , rainfall , winds , and ocean circulation . When the incoming solar energy is balanced by an equal flow of heat to space , the Earth is said to be in radiative equilibrium and under that condition , global temperatures will be stable . Disturbances of Earth 's radiative equilibrium , such as an increase of greenhouse gases , will change global temperatures in response . However , Earth 's energy balance and heat fluxes depend on many factors , such as atmospheric composition ( mainly aerosols and greenhouse gases ) , the albedo ( reflectivity ) of surface properties , cloud cover and vegetation and land use patterns . Changes in surface temperature due to Earth 's energy budget do not occur instantaneously , due to the inertia of the oceans and the cryosphere .

The Earth is much cooler and so radiates heat back away from itself at much longer wavelengths , mostly in the infrared range . The idealized greenhouse model is based on the fact that certain gases in the Earth 's atmosphere , including carbon dioxide and water vapour , are transparent to the high-frequency , high-energy solar radiation , but are much more opaque to the lower frequency infrared radiation leaving the surface of the earth . Thus heat is easily let in , but is partially trapped by these gases as it tries to leave . Rather than get hotter and hotter , Kirchhoff 's law of thermal radiation says that the gases of the atmosphere also have to re-emit the infrared energy that they absorb , and they do so , also at long infrared wavelengths , both upwards into space as well as downwards back towards the Earth 's surface . In the long-term , thermal equilibrium is reached when all the heat energy arriving on the planet is leaving again at the same rate . In this idealized model , the greenhouse gases cause the surface of the planet to be warmer than it would be without them , in order for the required amount of heat energy finally to be radiated out into space from the top of the atmosphere . The greenhouse effect can be illustrated with an idealized planet . This is a common `` textbook model '' : the planet will have a constant surface temperature Ts and an atmosphere with constant temperature Ta . For diagrammatic clarity , a gap can be depicted between the atmosphere and the surface . Alternatively , Ts could be interpreted as a temperature representative of the surface and the lower atmosphere , and Ta could be interpreted as the temperature of the upper atmosphere .

The difference in these three terms represents the amount of energy absorbed during the conversion of liquid water to vapor , which is ET . METRIC expresses near-surface temperature gradients used in heat convection as indexed functions of radiometric surface temperature , thereby eliminating the need for absolutely accurate surface temperature and the need for air-temperature measurements .

Slope and aspect functions and temperature lapsing are used for application to mountainous terrain . METRIC algorithms are designed for relatively routine application by trained engineers and other technical professionals who possess a familiarity with energy balance and basic radiation physics .

In the time since the industrial revolution the climate has increasingly been affected by human activities that are causing global warming and climate change.The climate system receives nearly all of its energy from the sun. The climate system also radiates energy to outer space. The balance of incoming and outgoing energy, and the passage of the energy through the climate system, determines Earth's energy budget. When the incoming energy is greater than the outgoing energy, earth's energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and earth experiences cooling. The energy moving through Earth's climate system finds expression in weather, varying on geographic scales and time. Long-term averages and variability of weather in a region constitute the region's climate. Such changes can be the result of \"internal variability\", when natural processes inherent to the various parts of the climate system alter the distribution of energy. Examples include variability in ocean basins such as the Pacific decadal oscillation and Atlantic multidecadal oscillation. Climate variability can also result from external forcing, when events outside of the climate system's components nonetheless produce changes within the system.

ATES is applied to provide heating and cooling to buildings . Storage and recovery of thermal energy is achieved by extraction and injection of groundwater from aquifers using groundwater wells . Systems commonly operate in a seasonal mode . The groundwater that is extracted in summer , is used for cooling by transferring heat from the building to the groundwater by means of a heat exchanger . Subsequently , the heated groundwater is injected back into the aquifer , which creates a storage of heated groundwater . In wintertime , the flow direction is reversed such that the heated groundwater is extracted and can be used for heating ( often in combination with a heat pump ) . Therefore , operating an ATES system uses the subsurface as a temporal storage to buffer seasonal variations in heating and cooling demand . When replacing traditional fossil fuel dependent heating and cooling systems , ATES can serve as a cost-effective technology to reduce the primary energy consumption of a building and the associated CO2 emissions . In 2009 United Nations Climate Change Conference in Copenhagen , Denmark , many countries and regions have made targets for global climate protection . The European Union also set a target to reduce greenhouse gas emissions , increase use of sustainable energy and improve energy efficiency . For this target , ATES can actually contribute significantly , as about 40 % of global energy consumption is done by buildings , and is mainly for heating and cooling . Therefore , the development of ATES has been paid a lot of attention and the number of ATES has increased dramatically , especially in Europe . For example , in the Netherlands , it was estimated that about 20,000 ATES systems could be achieved by 2020 .

The climate system also radiates energy to outer space. The balance of incoming and outgoing energy, and the passage of the energy through the climate system, determines Earth\\'s energy budget. When the incoming energy is greater than the outgoing energy, earth\\'s energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and earth experiences cooling.\\nThe energy moving through Earth\\'s climate system finds expression in weather, varying on geographic scales and time. Long-term averages and variability of weather in a region constitute the region\\'s climate. Such changes can be the result of \"internal variability\", when natural processes inherent to the various parts of the climate system alter the distribution of energy.

Climate change may cause variations in both temperature and snowfall , causing changes in the surface mass balance . Changes in mass balance control a glacier 's long-term behavior and are the most sensitive climate indicators on a glacier . From 1980 -- 2012 the mean cumulative mass loss of glaciers reporting mass balance to the World Glacier Monitoring Service is − 16 m . This includes 23 consecutive years of negative mass balances . A glacier with a sustained negative balance is out of equilibrium and will retreat , while one with a sustained positive balance is out of equilibrium and will advance . Glacier retreat results in the loss of the low elevation region of the glacier . Since higher elevations are cooler than lower ones , the disappearance of the lowest portion of the glacier reduces overall ablation , thereby increasing mass balance and potentially reestablishing equilibrium . However , if the mass balance of a significant portion of the accumulation zone of the glacier is negative , it is in disequilibrium with the local climate . Such a glacier will melt away with a continuation of this local climate . The key symptom of a glacier in disequilibrium is thinning along the entire length of the glacier . For example , Easton Glacier ( pictured below ) will likely shrink to half its size , but at a slowing rate of reduction , and stabilize at that size , despite the warmer temperature , over a few decades . However , the Grinnell Glacier ( pictured below ) will shrink at an increasing rate until it disappears . The difference is that the upper section of Easton Glacier remains healthy and snow-covered , while even the upper section of the Grinnell Glacier is bare , melting and has thinned . Small glaciers with shallow slopes such as Grinnell Glacier are most likely to fall into disequilibrium if there is a change in the local climate . In the case of positive mass balance , the glacier will continue to advance expanding its low elevation area , resulting in more melting . If this still does not create an equilibrium balance the glacier will continue to advance . If a glacier is near a large body of water , especially an ocean , the glacier may advance until iceberg calving losses bring about equilibrium .", "qid": "598", "docid": "Glacier_mass_balance", "rank": 34, "score": 93401 }, { "content": "Title: Low Emission Development Strategies Global Partnership (LEDS GP) Content: The Low Emissions Development Strategies Global Partnership ( LEDS GP ) aims to advance climate-resilient low emission development and support transitions to a low-carbon economy through coordination , information exchange and cooperation among countries and programs working to advance low-emission economic growth .

To provide the correct power output heating or cooling devices require a certain flow known as the design flow . Theoretically it is possible to design plants that deliver the design flow at each terminal unit ( heating or cooling device ) . In reality this is not possible because pipes and valves only come in certain sizes and accurately predicting the real flow in a system is too complex . Some circuits ( typically those closest to the pump ) will be favoured by higher than required flows at the expense of other circuits that will have underflows . In small heating systems ( e.g. domestic systems ) balancing is quite easy because of the small number of terminal units and relatively simple distribution network . Balancing can normally be achieved by simply pre-setting the flow through the radiators . Larger buildings , such as offices or hospitals , have a more complicated heating and cooling system and require a more accurate balancing technique . To obtain a plant with the correct design flows , consultants design systems to include balancing valves , differential pressure controllers or pressure independent control valves . Balancing valves allow the measurement of differential pressures which can be used to calculate a flow . There are various balancing methods but all involve measuring differential pressures and adjusting them to the correct value by calculating what flow that represents . Differential pressure controllers are usually membrane - or spring driven valves that control the differential pressures in the installation . This will simplify balancing procedures and enable the installation to be more precisely controlled . Pressure independent valves combine the balancing and control functions in one valve and work based on springs and/or membranes to precisely control the flows in the distribution network and as such need no measuring or balancing procedure .", "qid": "598", "docid": "Hydronic_balancing", "rank": 38, "score": 93052 }, { "content": "Title: Energy Charter Treaty Content: The Energy Charter Treaty ( ECT ) is an international agreement which establishes a multilateral framework for cross-border cooperation in the energy industry .

Colloquially , some refer to these organisms as `` cold blooded '' though such a term is not technically correct , as the blood temperature of the organism varies with ambient environmental temperature . Some of these animals live in environments where temperatures are practically constant , as is typical of regions of the abyssal ocean .

In contrast to ectotherms , endotherms rely largely , even predominantly , on heat from internal metabolic processes .

The GEM 's operational model , known as the Global Deterministic Prediction System ( GDPS ) , is currently operational for the global data assimilation cycle and medium-range forecasting , the regional data assimilation spin-up cycle and short-range forecasting . Furthermore , mesoscale forecasts ( distributed under the names Regional Deterministic Prediction System or RDPS for the coarser mesh and High Resolution Deterministic Prediction System or HRDPS for the finer mesh ) are produced overnight and are available to the operational forecasters . A growing number of meteorological applications are now either based on or use the GEM model .

These presently include short-range regional forecasting , medium-range global forecasting , and data assimilation . In the future they will include nowcasting at the meso-scales , and dynamic extended-range forecasting on monthly to seasonal timescales . The essence of the approach is to develop a single highly efficient model that can be reconfigured at run time to either run globally at uniform-resolution ( with possibly degraded resolution in the `` other '' hemisphere ) , or to run with variable resolution over a global domain such that high resolution is focused over an area of interest . The operational GEM model dynamics is formulated in terms of the hydrostatic primitive equations with a terrain following pressure vertical coordinate ( h ) . The time discretization is an implicit two-time-level semi-Lagrangian scheme . The spatial discretization is a Galerkin grid-point formulation on an Arakawa C-grid in the horizontal ( lat-lon ) and an unstaggered vertical discretization . The horizontal mesh can be of uniform or variable resolution , and furthermore can be arbitrarily rotated , the vertical mesh is also variable . The explicit horizontal diffusion is -2 on all prognostic variables .

It has been found that carbon dioxide from the burning of coal , natural gas , and oil for electricity and heat is the largest single source of global greenhouse gas emissions .

Despite these efforts the results are still far off and we continue to see growth in CO2 concentration . Now , a growing number of individuals are trying to make a reduction in the amount of CO2 that is being produced by participating in low carbon dieting . This small adjustment in household CO2 production has the potential to reduce emissions much more quickly than other kinds of changes and it deserves explicit consideration as part of climate policy .

Following the introduction of the detent chronometer escapement with a temperature compensated balance , very close rates could be achieved in marine chronometers and to a lesser degree in pocket chronometers . This achievement was due , other things being equal , to the minimal interference with the balance during unlocking and impulse . A further key advantage of this escapement was that there was no need for oil on the escapement 's working surfaces and hence no deterioration in the friction between the working surfaces as the oil aged . A drawback was that the detent escapement as it was used in pocket chronometers was prone to stopping as a result of motion . Most escapements are capable of being stopped by a sudden movement but the detent escapement gives an impulse to the balance only when it is moving in one direction . The escapement is therefore not self-starting . The lever escapement , as used in most modern mechanical watches , avoided this problem . In common with most other escapements it gave an impulse to the balance in both directions of the balance swing . This creates another problem in doing so because the introduction of a lever between the balance and the final ( escape ) wheel of the escapement requires lubrication on the acting surfaces .", "qid": "598", "docid": "Echappement_naturel", "rank": 56, "score": 86969 }, { "content": "Title: LOWERN Content: LOWERN is an acronym for 6 factors that affect climate .

When air rises it expands due to low air pressure which causes it to cool . Relief . The differences in the elevation in land . As air is forced to rise over a piece of land ( e.g. a mountain ) the temperature decreases and condensation increases . As it condensates water droplets get bigger and heavier and are forced to fall . Once the air mass goes over the mountain the temperature and evaporation increases but condensations decreases , resulting in a halt in precipitation and rain shadows . Nearness to Water . Water heats up and cools down slower than land does , having a moderating effect . On colder days , the water heats up the land , whereas on hotter days , the land is cooled down by the water .

It is called anomalous because the heat capacity usually increases with temperature , or stays constant . It occurs in systems with a limited number of energy levels so that E ( T ) increases with sharp steps , one for each energy level that becomes available . Since Cv = ( dE/dT ) , it will experience a large peak as the temperature crosses over from one step to the next . This effect can be explained by looking at the change in entropy of the system . At zero temperature only the lowest energy level is occupied , entropy is zero , and there is very little probability of a transition to a higher energy level . As the temperature increases , there is an increase in entropy and thus the probability of a transition goes up . As the temperature approaches the difference between the energy levels there is a broad peak in the specific heat corresponding to a large change in entropy for a small change in temperature . At high temperatures all of the levels are populated evenly , so there is again little change in entropy for small changes in temperature , and thus a lower specific heat capacity . For a two level system the specific heat coming from the Schottky anomaly has the form : Where kBΔ is the energy between the two levels . This anomaly is usually seen in paramagnetic salts or even ordinary glass ( due to paramagnetic iron impurities ) at low temperature . At high temperature the paramagnetic spins have many spin states available , but at low temperatures some of the spin states are `` frozen out '' ( having too high energy due to crystal field splitting ) , and the entropy per impurity is lowered .

Photovoltaics ( PV ) were the ideal way of powering this equipment , because there was no grid electricity . Many other opportunities for PV became apparent to Lacayo , like home lighting , battery-charging , water pumping and refrigeration . Over the years the provision of renewable energy systems became more important than communications and is now the main activity of ECAMI . ECAMI routinely supplies and installs solar-homes PV systems in rural areas . ECAMI designs and installs PV-powered mini grids to provide power for homes , hotels , museums and planned health centers in small communities . Underground distribution systems connect all the users to the supply , with individual current limits to each facility . ECAMI installs PV supply systems for mobile phone masts , with considerable savings in fuel diesel . In Managua , the capital of Nicaragua , six hotels have been supplied with solar water heating systems by ECAMI . One with 50 m2 of panel area supplies 100 rooms each of which had previously required a 6 kW immersion heater , another with 16 m2 of panels supplies 40 rooms . About 150 domestic solar water-heaters have also been installed . ECAMI supplies and installs small wind turbines of between 400 W and 5 kW output , and can also install hydro-electric system . The benefits of the thousands of renewable energy systems installed by ECAMI are considerable : more than 100,000 people have been benefited in Nicaragua while the use of CO2 emitting fuels and air pollution is being reduced . The social and economic benefits are perceived through longer hours of emergency service in health centers , the installations of water pumps that bring drinking water to distant communities , the access of satellite internet , land irrigation , longer and more efficient working hours , etc. . Luis Lacayo 's wife Claudia , a lawyer , joined ECAMI in 1997 to manage the administration and contracts , and their son Max Lacayo , also a lawyer , is now the marketing director .

While the Directive 's primary aim is to reduce energy use , it is also aimed at enforcing other environmental considerations including : materials use ; water use ; polluting emissions ; waste issues and recyclability . The Ecodesign Directive is a framework directive , meaning that it does not directly set minimum ecological requirements . These are adopted through specific implementing measures for each group of products in the scope of the Directive . The implementing measures are adopted through the so-called comitology procedure .

The technique of measuring electrochemical noise uses no applied external signal for the collection of experimental data . The ECN technique measures the signal perturbations which are low level fluctuations of the corrosion potential between two nominally identical electrodes which can be used in the mechanistic determination of corrosion type and speed . The fluctuations are usually of low amplitude , less than 1 mV and of low frequency bandpass filtered RMS value ( DC and high frequency AC components removed ) . The noise corresponds with the low level frequency noise ( differential of the ZRA ) signal but has a much lower amplitude when general corrosion is involved . The technique considers the reactions occurring at the metal -- solution interface and suggests two currents flowing on each electrode as a result of the anodic and cathodic reactions . Once regarded as a source of bias and error that compromised electrochemical measurements it is now regarded as a rich source of information . The technique is widely used within the Corrosion engineering world as a useful Corrosion Monitoring technique .

Dicynodonts were a diverse clade that inhabited the earth from the Middle Permian to the Late Triassic . Kombuisia is one of few species to survive the mass extinction event in the late Permian . Kombuisia are non-mammalian synapsid herbivores . Specimens of this genus were discovered in the 1960s and 1970s and years later were determined to be two different species of the genus . The two species were found in diverse areas , K. frerensis in South Africa and K. antarctica in Antarctica . This indicated that this genus existed in a wider biographical region in the southern hemisphere of Pangaea and believed by some to indicate the migration to Antarctica to avoid the rise in global temperatures that lead to the mass extinction . Migration to avoid global warming has been highly controversial because many of the fossils that are found in this region are juvenile and of small body size . Originally the specimens that were collected in Antarctica were considered to be part of the Kingoria ( now known as Dicynodontoides ) genus . The specimens were originally catalogued in the American Museum of Natural History as Kingoria , however , with no formal reasoning for this categorization , this has since been revised with more up-to-date knowledge of features and speciation .

Since the 1980s , decreases in amphibian populations , including population crashes and mass localized extinctions , have been observed in locations all over the world . These declines are known as one of the most critical threats to global biodiversity , and several causes are believed to be involved , including disease , habitat destruction and modification , exploitation , pollution , pesticide use , introduced species , and ultraviolet-B radiation ( UV-B ) . However , many of the causes of amphibian declines are still poorly understood , and the topic is currently a subject of much ongoing research . Calculations based on extinction rates suggest that the current extinction rate of amphibians could be 211 times greater than the background extinction rate and the estimate goes up to 25,000 -- 45,000 times if endangered species are also included in the computation . Although scientists began observing reduced populations of several European amphibian species already in the 1950s , awareness of the phenomenon as a global problem and its subsequent classification as a modern-day mass extinction only dates from the 1980s . By 1993 , more than 500 species of frogs and salamanders present on all five continents were in decline .

Climate change may cause variations in both temperature and snowfall , causing changes in the surface mass balance . Changes in mass balance control a glacier 's long-term behavior and are the most sensitive climate indicators on a glacier . From 1980 -- 2012 the mean cumulative mass loss of glaciers reporting mass balance to the World Glacier Monitoring Service is − 16 m . This includes 23 consecutive years of negative mass balances . A glacier with a sustained negative balance is out of equilibrium and will retreat , while one with a sustained positive balance is out of equilibrium and will advance . Glacier retreat results in the loss of the low elevation region of the glacier . Since higher elevations are cooler than lower ones , the disappearance of the lowest portion of the glacier reduces overall ablation , thereby increasing mass balance and potentially reestablishing equilibrium . However , if the mass balance of a significant portion of the accumulation zone of the glacier is negative , it is in disequilibrium with the local climate . Such a glacier will melt away with a continuation of this local climate . The key symptom of a glacier in disequilibrium is thinning along the entire length of the glacier . For example , Easton Glacier ( pictured below ) will likely shrink to half its size , but at a slowing rate of reduction , and stabilize at that size , despite the warmer temperature , over a few decades . However , the Grinnell Glacier ( pictured below ) will shrink at an increasing rate until it disappears . The difference is that the upper section of Easton Glacier remains healthy and snow-covered , while even the upper section of the Grinnell Glacier is bare , melting and has thinned . Small glaciers with shallow slopes such as Grinnell Glacier are most likely to fall into disequilibrium if there is a change in the local climate . In the case of positive mass balance , the glacier will continue to advance expanding its low elevation area , resulting in more melting . If this still does not create an equilibrium balance the glacier will continue to advance . If a glacier is near a large body of water , especially an ocean , the glacier may advance until iceberg calving losses bring about equilibrium .", "qid": "603", "docid": "Glacier_mass_balance", "rank": 34, "score": 73569 }, { "content": "Title: Antarctic Treaty System Content: The Antarctic Treaty and related agreements , collectively known as the Antarctic Treaty System ( ATS ) , regulate international relations with respect to Antarctica , Earth 's only continent without a native human population .

The study reported here identified that the impact of the iceberg B09B on the penguins since 2010 . The number of penguins breeding at these colonies has declined markedly since estimates were first made 100 years ago . However our study concerns only the impact B09B and the associated fast ice that has built up between it and the land since the iceberg stranded in 2010 . The penguins now have to commute about 65 km between colonies where they breed and the sea where they can feed . Many fewer penguins are now returning to the colonies to attempt to breed and of those that do return most fail to rear their chicks . We found hundreds of abandoned eggs and thousands of dead chicks . We did not suggest that thousands of adult penguins have died as some media reports suggest . In fact it is unlikely many if any adult penguins have died as a result of this stranding event . We found very few , perhaps no pre-breeding birds at Cape Denison and , if as we predict , few if any young birds prospecting for a place to breed in future are visiting these colonies the local colonies could become extinct within the breeding life of an Adelie penguins ( < 16 years ) if young birds do not replace the old established breeders as they come to the end of their lives .

It began when the ship broke loose from its anchorage in McMurdo Sound in May 1915 , during a gale . Caught in heavy pack ice and unable to manoeuvre , Aurora , with eighteen men aboard , was carried into the open waters of the Ross Sea and Southern Ocean , leaving ten men stranded ashore with meagre provisions . Aurora , a 40-year-old former Arctic whaler registered as a steam yacht , had brought the Ross Sea party to Cape Evans in McMurdo Sound in January 1915 , to establish its base there in support of Shackleton 's proposed transcontinental crossing . When Aurora 's captain Aeneas Mackintosh took charge of activities ashore , first officer Joseph Stenhouse assumed command of the ship . Stenhouse 's inexperience may have contributed to the choice of an inappropriate winter 's berth , although his options were restricted by the instructions of his superiors . After the ship was blown away it suffered severe damage in the ice , including the destruction of its rudder and the loss of its anchors ; on several occasions its situation was such that Stenhouse considered abandonment . Efforts to make wireless contact with Cape Evans and , later , with stations in New Zealand and Australia , were unavailing ; the drift extended through the southern winter and spring to reach a position north of the Antarctic Circle . In February 1916 the ice finally broke up , and a month later the ship was free . It was subsequently able to reach New Zealand for repairs and resupply , before returning to Antarctica to rescue the surviving members of the shore party . Despite his role in saving the ship , after Aurora 's arrival in Port Chalmers Stenhouse was removed from command by the organisers of the Ross Sea party relief expedition , so the ship returned to McMurdo Sound under a new commander and with a substantially different crew .

Ice shelves are only found in Antarctica , Greenland , Canada and the Russian Arctic . The boundary between the floating ice shelf and the grounded ( resting on bedrock ) ice that feeds it is called the grounding line . The thickness of ice shelves ranges from about 100 to 1000 meters . In contrast , sea ice is formed on water , is much thinner ( typically less than 3m ) , and forms throughout the Arctic Ocean . It also is found in the Southern Ocean around the continent of Antarctica . Ice shelves are principally driven by gravity-driven pressure from the grounded ice . That flow continually moves ice from the grounding line to the seaward front of the shelf . The primary mechanism of mass loss from ice shelves was thought to have been iceberg calving , in which a chunk of ice breaks off from the seaward front of the shelf . A study by NASA and university researchers - published in the June 14 , 2013 issue of Science - found however that ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent 's ice shelf mass loss . Typically , a shelf front will extend forward for years or decades between major calving events . Snow accumulation on the upper surface and melting from the lower surface are also important to the mass balance of an ice shelf . Ice may also accrete onto the underside of the shelf . The density contrast between glacial ice , which is denser than normal ice , and liquid water means that only about 1/9 of the floating ice is above the ocean surface .

Many of these sediments were deposited before the ice sheet occupied the region , when much of West Antarctica was covered by the ocean . The rapid ice-stream flow is a non-linear process still not fully understood ; streams can start and stop for unclear reasons .

It encompasses the Ross Sea , the area under the Ross Ice Shelf and a part of West Antarctica . Its evolution is due to lithospheric thinning of the non-cratonic area of West Antarctica . Exploration of the geology of the West Antarctic Rift is difficult , because , apart from peaks of the Transantarctic Mountains that protrude above the ice , the region is covered by the vast West Antarctic Ice Sheet . Thus , the rift is less well known than other major rift valleys . It is known , however , that like the East African Rift , the West Antarctic Rift is actually a number of much shorter rifts that cross Antarctica . There is also a sharp division between older , broader Paleogene rifts including the Ross Sea Basin and the younger , narrower Terror Rift . There are also a large number of failed rifts extending as far as Berkner Island . Although many rifts within the West Antarctic Rift system are no longer active , it is now known that West Antarctica is moving away from the East Antarctic Craton in a north/northeasterly direction ( approximately in the direction of the South Georgia Islands ) at a rate of about 2 mm per year or 500,000 years per kilometre . The West Antarctic Rift is the source of all the recently active volcanoes within Antarctica , and of most of the major Antarctic mountain systems outside the Antarctic Peninsula . It is also believed to have a major influence on ice flows in West Antarctica , because fast moving ice streams are believed to be influenced by the lubrication provided by water-saturated till , which some argue could help cause breakup of the ice sheet if global warming accelerates .", "qid": "609", "docid": "West_Antarctic_Rift", "rank": 30, "score": 132478 }, { "content": "Title: John H.

Mercer ( Cheltenham , England , 19 October 1922 -- Columbus , Ohio 3 July 1987 ) was a glaciologist , chiefly known for his theoretical work on , and field studies of Antarctic ice streams , especially in the Transantarctic Mountains and in West Antarctica . Following John T. Hollin 's work ( 1962 ) suggesting that climatic warming and rising sea-level cause Antarctic ice shelves to retreat , Mercer postulated that the West Antarctic ice sheet , being grounded well below sea-level and terminating in floating ice shelves , was vulnerable to these changes and may have collapsed altogether during the last interglacial when Antarctica may have been warmer and sea-level may have been higher . In 1978 , in the science magazine Nature , Mercer pointed out that `` green-house '' warming from burning fossil fuel could have the same effect during the present interglacial . Two studies published 12 May 2014 confirm Mercer 's assumption . Climate scientist James Hansen has coined the term , `` John Mercer effect . '' After Mercer published his paper suggesting that the West Antarctic ice sheet could collapse in response to warming , he struggled to get funding . Others , including Hansen , had similar problems . Many climate scientists censor their own work to avoid losing funding , especially regarding prospects for limiting warming to 2 ° C above pre-industrial temperatures . John H. Mercer was the third child of Harriet and John W. Mercer . He was educated at private schools in Cheltenham and , later , at Gordonstoun in Scotland . During World War II he served in the British Merchant Marines ( 1940 -- 46 ) as a radio man . After the war he went to University of Cambridge and studied geography . At that time he came under the influence of William Vaughan Lewis . After finishing his B.A. in 1949 Mercer went to Canada , where he received his PhD in geography from McGill University in 1954 . He was a Research Scholar from 1954 to 1956 at the Australian National University in Canberra , where he studied land use and population in western Samoa .

Such meteorites are quickly covered by subsequent snowfall and begin a centuries-long journey traveling `` downhill '' across the Antarctic continent while embedded in a vast sheet of flowing ice . Portions of such flowing ice can be halted by natural barriers such as the Transantarctic Mountains . Subsequent wind erosion of the motionless ice brings trapped meteorites back to the surface once more where they may be collected .

Its task was to lay a series of supply depots across the Great Ice Barrier from the Ross Sea to the Beardmore Glacier , along the polar route established by earlier Antarctic expeditions . The expedition 's main party , under Shackleton , was to land near Vahsel Bay on the opposite coast of Antarctica , and to march across the continent via the South Pole to the Ross Sea . As the main party would be unable to carry sufficient fuel and supplies for the whole distance , their survival depended on the Ross Sea party setting up supply depots , which would cover the final quarter of their journey . Shackleton set sail from London on his ship Endurance , bound for the Weddell Sea in August 1914 . Meanwhile , the Ross Sea party personnel gathered in Australia , prior to departure for the Ross Sea in the second expedition ship , SY Aurora . Organisational and financial problems delayed their start until December 1914 , which shortened their first depot-laying season . After their arrival the inexperienced party struggled to master the art of Antarctic travel , in the process losing most of their sled dogs . A greater misfortune occurred at the onset of the southern winter when the Aurora , locked in an ice-floe which broke off from the main shelf , was torn from its moorings . The ocean currents then pulled ship further away from the sledding parties marooned on shore and drifted for over six months before breaking free of the ice . Sadly the Aurora 's damaged rudder forced her to return to New Zealand rather than returning for the stranded shore party . Despite these setbacks , the Ross Sea party survived inter-personnel disputes , extreme weather , illness , and the deaths of three of its members to carry out its mission in full during its second Antarctic season . This success proved ultimately without purpose , because Shackleton 's main expedition was unable to land after Endurance was crushed in the Weddell Sea ice . Shackleton eventually led his men to safety , but the transcontinental march did not take place and the Ross Sea party 's depots were not required . The Ross Sea party remained stranded until January 1917 , when Aurora , which had been repaired and refitted in New Zealand , arrived to rescue them . Public recognition of their efforts was slow in coming , but in due course four Albert Medals were awarded to members of the party , two posthumously .

The river begins at Lake Chapala and continues roughly north-west through the Sierra Madre Occidental , receiving the Verde , Juchipila , Bolaños , and other tributaries . At La Yesca , the La Yesca Dam was completed in 2012 and the El Cajón Dam was completed downstream in 2007 . Below El Cajón , the Aguamilpa Dam was completed in 1993 , creating a reservoir covering a large part of the territory of the municipality of El Nayar in Nayarit . From Aguamilpa , the river descends to the coastal lowlands , passing by Santiago Ixcuintla and empties into the Pacific Ocean , 16 km northwest of San Blas , in Nayarit . The river is viewed by some sources as a continuation of the Lerma River , which flows into Lake Chapala . Mexico possesses a small percentage of the world 's freshwater reserve , 0.1 % . According to an article named Water use ( and abuse ) and its effects on the crater-lake Valle de Santiago , Mexico `` most Mexican lakes are in an advanced state of desiccation or senescence , with volumes and surface area greatly reduced because of human activities '' ( page 145 ) . Some examples of these damaging activities are wood cutting , inflow diversion for agriculture , groundwater over extraction , pollution and eutrophication . Together Rio Lerma Santiago is a little over 600 miles long , but alone Rio Santiago is reported to be 269 miles long . It is an extension of the Lerma River , which at 466 miles long it is one of Mexico 's longest rivers . The water begins in the Mexican Plateau in Mexico City . Then travels westward and goes through the Lerma River , and empties in Lake Chapala , near Guadalajara . From there the water flows southward through Rio Santiago and dissipates to the Pacific Ocean near San Blas , in Nayarit . According to an article named Impacts from contamination of the Santiago River on the well-being of the inhabitants of El Salto , Jalisco the river passes by `` Ocotlán , Poncitlán , Atequiza , Atotonilquillo , Juanacatlán , , El Salto , Tonalá among others '' ( Gonzalez and Hernandez , page 711 ) . Less than 50 years ago the river was once a place to fish , bathe , and swim . It is now a river full of pollutants , with a smell that can only be described as worse than rotten eggs . This river is not the most polluted river ever but it is one of the worst polluted in Mexico . It does n't only hurt locals , but all of Mexico which rely on the river for water supply and food . Up until the 1980s this river was a beautiful place to live and visit . Luz Moreno remembers when she was a little girl playing and swimming in the river . `` Many tourists came not only from Mexico but from the US to see the falls ( El Salto Falls ) '' Moreno says `` which at one time ... I am not sure if they still do ... powered the factories '' . Concepcion Garcia , who still lives near the river , also remembers a time when you could eat the fish from the river `` People would fish and bring it home to cook and serve . I ca n't imagine that happening anymore '' . `` It was probably until the 80s when we stopped playing in the river '' Moreno says . That 's when Moreno claims that the river was rerouted to serve the bigger cities and stopped the flow in her own hometown . `` The water stayed still and was not very deep ... the factories made it worse by dumping all of their sewage water in . The water no longer flowed and cleaned itself it just sat there getting worse '' Moreno remembers . On a bad day in Garcia 's home , with the wind blowing her way , you can smell what can only be described as rotten eggs caused by the river . `` The smell is indescribable , but I know it 's because of the river '' Garcia says . Locals also think that the river causes cancer . `` I know that the river causes cancer . We did n't have a problem before the river stopped flowing ... All of the sudden the river stops flowing and then we have all of these problems with cancer among the locals '' ( Garcia ) . While no official studies have been done to connect cancer to living next to the river , the locals are convinced , and whenever someone gets cancer they blame it on the polluted river . According to Gonzalez and Hernandez the University of Guadalajara had conducted studies where they found `` fecal coliform levels 110 times above the recommended limit and lead concentrations , zinc , ammonia and phosphate threatening animal and plant life '' ( page 712 ) which is partially the governments fault for not regulating the things dumped in the river . Locals would like their river back to its former glory , but that day seems very far away and most locals do n't know where to start . Many people ask why this river is so polluted . It 's a combination of factory sewage dumping such as pulp and paper mills and leather processing plants . We can also blame this on petrochemical dumping and local farms that have dumped fertilizers and chemicals introduced by meat and dairy . If you look further most of the polluting is done by the big factories that have resided on both sides of the river , but some can also be blamed on locals . Farmers mostly have contributed to the contamination of their beloved river . In my opinion it all boils down to lack of education and regulations . Maybe if the Mexican government had put in more thought ( and money ) in to the future and cleaning of the river it would n't be that as horrible as it is today . Many locals blame the factories `` there were so many factories ... they would make all kinds of things ... Levis the jean company was once there , Hershey 's was there , I worked there for a while , and they would all dump into a river that did n't flow '' ( Garcia ) . The thing that locals fail to realize is that they are also part of the problem . Not only do the locals work in these factories , the ones who do n't ( farmers ) also dump into the river . I am not saying that the factory workers should quit their factory jobs and not support their families , but to educate themselves on what they are doing for a living and how it effects the environment . In February 2008 an eight-year-old boy , Miguel Angel Lopez Rocha , died after he fell into the river . Rocha fell near the El Salto Falls , where not that long ago tourists came from all over the world to see the falls . He died nineteen days after he fell into the river . One autopsy indicated heavy metal poison was the reason for his death . This even brought attention to one of Mexico 's worst environmental disasters . `` When Miguel died , an invisible problem became visible '' said Maria Gonzalez from the Mexican Institute for Community Development . After the unfortunate incident many locals organized a group called `` A Leap of Life '' . According to Gonzalez and Hernandez `` this made it possible to carry out the Second National Assembly Environmentally Affected by the end of May 2009 in El Salto '' ( 713 ) . Their goal is to join the national movement that brings together communities and organizational . `` They are struggling to defend their resources , the right to health and to a healthy environment '' ( Gonzalez and Hernandez , page 713 ) . Since Gonzalez and Hernandez 's article was published in 2009 , they did n't get to mention that the National Commission for Human Health tried to declare the area of El Salto an Emergency Zone . They failed because the Secretary of Environment and Natural Resources refused , he feared it would hurt the economy . Also , in the past decade the National Water Commission has not reported a single fine for illegal discharge of chemical waste into the river . When something of this magnitude happens you expect your government to help or regulate the problem , but instead it is up to the locals to try and convince the government to spend their money to save the river . This environmental disaster not only effects humans , but animals as well . Just like all food chains there is always a predator and its prey . Whatever the prey eats , it will effects the predator . Rio Santiago used to be a river thriving with fish . These fish were then eaten by other animals or by humans . If the fish are contaminated then the predators ( humans and other animals ) are most likely going to be negatively affected . `` In the 1980s , when things started to get bad , people stopped fishing , and had to find some other way to find food . A tradition that had been passed down from generation to generation got tossed away after a couple of years '' ( Garcia ) . When one part of the food chain goes away the system has to find a new way to arrange itself to satisfy everyone . Many things contributed to the pollution in Rio Santiago . Some say it is big corporate factories and businesses that should clean it up because it was their fault . Others say it was the locals who contaminated the lake . The thing is that whatever way the river got contaminated , the fact of the matter is that it needs to be cleaned up , and people need to be educated on how to properly dispose of their waste . It is also up to the government to constantly regulate and punish anyone who violates the regulations . The fact of the matter is that whichever way the river got contaminated in the first place it is everyone 's job to help clean up and to respect what mother nature has given us , because we might not get another chance . This not only goes for Rio Santiago , but for all polluted areas .", "qid": "614", "docid": "Grande_de_Santiago_River", "rank": 44, "score": 140384 }, { "content": "Title: Grande de San Miguel River Content: Río Grande de San Miguel is a river in southern El Salvador , Central America .

The 1450 mi river drains an expansive , arid watershed that encompasses parts of seven U.S. and two Mexican states . Starting in the central Rocky Mountains in the U.S. , the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona -- Nevada border , where it turns south toward the international border . After entering Mexico , the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora . Known for its dramatic canyons , whitewater rapids , and eleven U.S. National Parks , the Colorado River system is a vital source of water for 40 million people in southwestern North America . The river and its tributaries are controlled by an extensive system of dams , reservoirs , and aqueducts , which in most years divert its entire flow for agricultural irrigation and domestic water supply . Its large flow and steep gradient are used for generating hydroelectric power , and its major dams regulate peaking power demands in much of the Intermountain West . Intensive water consumption has dried up the lower 100 mi of the river , which has rarely reached the sea since the 1960s . Beginning with small bands of nomadic hunter-gatherers , Native Americans have inhabited the Colorado River basin for at least 8,000 years . Between 2,000 and 1,000 years ago , the river and its tributaries fostered large agricultural civilizations -- some of the most sophisticated indigenous cultures in North America -- which eventually faded due to a combination of severe drought and poor land use practices . Most native peoples that inhabit the basin today are descended from other groups that settled in the region beginning about 1,000 years ago . Europeans first entered the Colorado Basin in the 16th century , when explorers from Spain began mapping and claiming the area , which later became part of Mexico upon its independence in 1821 . Early contact between Europeans and Native Americans was generally limited to the fur trade in the headwaters and sporadic trade interactions along the lower river . After most of the Colorado River basin became part of the U.S. in 1846 , the bulk of the river 's course was still the subject of myths and speculation . Several expeditions charted the Colorado in the mid-19th century -- one of which , led by John Wesley Powell , was the first to run the rapids of the Grand Canyon . American explorers collected valuable information that was later used to develop the river for navigation and water supply . Large-scale settlement of the lower basin began in the mid - to late-19th century , with steamboats providing transportation from the Gulf of California to landings along the river that linked to wagon roads to the interior . Lesser numbers settled in the upper basin , which was the scene of major gold strikes in the 1860s and 1870s . Large engineering works began around the start of the 20th century , with major guidelines established in a series of international and U.S. interstate treaties known as the `` Law of the River '' . The U.S. federal government was the main driving force behind the construction of dams and aqueducts , although many state and local water agencies were also involved . Most of the major dams were built between 1910 and 1970 ; the system keystone , Hoover Dam , was completed in 1935 . The Colorado is now considered among the most controlled and litigated rivers in the world , with every drop of its water fully allocated . The environmental movement in the American Southwest has opposed the damming and diversion of the Colorado River system because of detrimental effects on the ecology and natural beauty of the river and its tributaries . During the construction of Glen Canyon Dam , environmental organizations vowed to block any further development of the river , and a number of later dam and aqueduct proposals were defeated by citizen opposition . As demands for Colorado River water continue to rise , the level of human development and control of the river continues to generate controversy .", "qid": "614", "docid": "Colorado_River", "rank": 91, "score": 131897 }, { "content": "Title: Rio Grande, New Jersey Content: Rio Grande ( -LSB- rioʊɡrʌndeɪ -RSB- ) is an unincorporated community and census-designated place ( CDP ) located within Middle Township in Cape May County , New Jersey , United States .

The total area of the diocese is 153394 sqmi . According to the 2006 parochial report , there are 57 active congregations within the diocese . The see is based in Albuquerque , New Mexico and the diocesan cathedral is the Cathedral Church of St. John . The 1859 General Convention of the Episcopal Church assigned New Mexico to the jurisdiction of the Missionary District of the Northwest under Josiah Cruickshank Talbot . Talbot first visited the region in 1863 , during the abortive attempt by Padre Jose Antonio Martinez of Taos to ally himself and his Roman Catholic congregations with the Episcopal Church . In 1874 , the General Convention of the Episcopal Church approved the formation of the Missionary District of New Mexico and Arizona and appointed William Forbes Adams as Bishop of the new mission . He first traveled to Albuquerque in 1875 , when nine people attended the first Episcopal worship service at the Exchange Hotel on the Plaza , on March 4 , 1875 . Adams resigned in 1877 and was succeeded by George Dunlop , under whose presidency the first convention of the Missionary District of New Mexico and Arizona was held , again at the Exchange Hotel , in 1880 . Dunlop is counted as the first diocesan bishop of the region that went on to be known from 1920 as the Missionary District of New Mexico and South West Texas ; from 1952 as the Episcopal Diocese of New Mexico ( later the Episcopal Diocese of the Rio Grande ) . The election of Terence Kelshaw in 1989 inaugurated a period of change not unmixed with controversy for the diocese . Kelshaw was a theological conservative and declined to support ventures and projects whether at local , national or international level that were not in alignment with conservative views . He was particularly vocal on the importance of traditional values in matters of sexual morality . Kelshaw gradually withdrew from the life of the national church and , by the time of his retirement , Rio Grande was widely regarded as among the most conservative dioceses in the Episcopal Church . The extent to which Kelshaw 's episcopate saw the development of a staunchly conservative approach in a sizable proportion of diocesan life was evident at the convention held to elect his successor , where the nominees included Martyn Minns , the high-profile conservative Rector of Truro Church ( Fairfax , Virginia ) who would go on , in June 2006 , to be elected Missionary Bishop of the Convocation of Anglicans in North America ( CANA ) , a missionary initiative of the Anglican Church of Nigeria primarily comprising congregations that have disaffiliated from the Episcopal Church . Steenson shared his predecessor 's theological conservatism , though unlike Kelshaw , he came from an Anglo-Catholic background . He voiced repeated and increasing concern about the direction of the Episcopal Church , and ultimately determined he should resign his position and orders , and become a Roman Catholic . He resigned in September 2007 , and was subsequently received into the Roman Catholic Church .

In 2012 , the United States experienced its warmest year on record . , the thirteen warmest years for the entire planet have all occurred since 1998 , transcending those from 1880 . From 1950 to 2009 , the American government 's surface temperature record shows an increase by 1 F-change , approximately . Global warming has caused many changes in the U.S. . According to a 2009 statement by the National Oceanic and Atmospheric Administration ( NOAA ) , trends include lake and river ice melting earlier in the spring , plants blooming earlier , multiple animal species shifting their habitat ranges northward , and reductions in the size of glaciers . Predicting future climate changes are fraught with difficulty . Some research has warned against possible problems due to American climate changes such as the spread of invasive species and possibilities of floods as well as droughts . Changes in climate in the regions of the United States appear significant . Drought conditions appear to be worsening in the southwest while improving in the northeast for example . President Barack Obama committed in the December 2009 Copenhagen Climate Change Summit to reduce carbon dioxide emissions in the range of 17 % below 2005 levels by 2020 , 42 % below 2005 levels by 2030 , and 83 % below 2005 levels by 2050 . In an address towards the U.S. Congress in June 2013 , Obama detailed a specific action plan to achieve the 17 % carbon emissions cut from 2005 by 2020 . He included such measures as shifting from coal-based power generation to solar and natural gas production . Climate change is seen as a national security threat to the United States . In 2015 , according to The New York Times and others , oil companies knew that burning oil and gas could cause global warming since the 1970s but , nonetheless , funded deniers for years . 2016 was an historic year for billion-dollar weather and climate disasters in U.S.", "qid": "615", "docid": "Climate_change_in_the_United_States", "rank": 1, "score": 164158 }, { "content": "Title: Greenhouse gas Content: A greenhouse gas ( abbrev .

Without greenhouse gases , the average temperature of Earth 's surface would be about -18 ° C , rather than the present average of 15 ° C . In the Solar System , the atmospheres of Venus , Mars and Titan also contain gases that cause a greenhouse effect . Human activities since the beginning of the Industrial Revolution ( taken as the year 1750 ) have produced a 40 % increase in the atmospheric concentration of carbon dioxide , from 280 ppm in 1750 to 406 ppm in early 2017 . This increase has occurred despite the uptake of a large portion of the emissions by various natural `` sinks '' involved in the carbon cycle . Anthropogenic carbon dioxide emissions ( i.e. , emissions produced by human activities ) come from combustion of fossil fuels , principally coal , oil , and natural gas , along with deforestation , soil erosion and animal agriculture . It has been estimated that if greenhouse gas emissions continue at the present rate , Earth 's surface temperature could exceed historical values as early as 2047 , with potentially harmful effects on ecosystems , biodiversity and the livelihoods of people worldwide .

As approximately 97 % of publishing climate scientists support the consensus on anthropogenic climate change , this list represents a minority viewpoint . The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering .

These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making .

If a planet 's atmosphere contains radiatively active gases ( i.e. , greenhouse gases ) the atmosphere will radiate energy in all directions . Part of this radiation is directed towards the surface , warming it . The downward component of this radiation -- that is , the strength of the greenhouse effect -- will depend on the atmosphere 's temperature and on the amount of greenhouse gases that the atmosphere contains . On Earth , the atmosphere is warmed by absorption of infrared thermal radiation from the underlying surface ( heated by the sun ) , absorption of shorter wavelength radiant energy from the sun , and convective heat fluxes from the surface . Greenhouse gases in the atmosphere radiate energy , some of which is directed to the surface and lower atmosphere . The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect . Earth 's natural greenhouse effect is critical to supporting life . Human activities , primarily the burning of fossil fuels and clearing of forests , have intensified the natural greenhouse effect , causing global warming .

This format was followed in subsequent Assessment Reports . The executive summary of the policymakers ' summary of the WG I report includes : We are certain of the following : there is a natural greenhouse effect ... ; emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases : CO2 , methane , CFCs and nitrous oxide . These increases will enhance the greenhouse effect , resulting on average in an additional warming of the Earth 's surface . The main greenhouse gas , water vapour , will increase in response to global warming and further enhance it . We calculate with confidence that : ... CO2 has been responsible for over half the enhanced greenhouse effect ; long-lived gases would require immediate reductions in emissions from human activities of over 60 % to stabilise their concentrations at today 's levels ... Based on current models , we predict : under -LSB- BAU -RSB- increase of global mean temperature during the -LSB- 21st -RSB- century of about 0.3 oC per decade ( with an uncertainty range of 0.2 to 0.5 oC per decade ) ; this is greater than that seen over the past 10,000 years ; under other ... scenarios which assume progressively increasing levels of controls , rates of increase in global mean temperature of about 0.2 oC -LSB- to -RSB- about 0.1 oC per decade . There are many uncertainties in our predictions particularly with regard to the timing , magnitude and regional patterns of climate change , due to our incomplete understanding of : sources and sinks of GHGs ; clouds ; oceans ; polar ice sheets . Our judgement is that : global mean surface air temperature has increased by 0.3 to 0.6 oC over the last 100 years ... ; The size of this warming is broadly consistent with predictions of climate models , but it is also of the same magnitude as natural climate variability . Thus the observed increase could be largely due to this natural variability ; alternatively this variability and other human factors could have offset a still larger human-induced greenhouse warming . The unequivocal detection of the enhanced greenhouse effect is not likely for a decade or more . under the IPCC business as usual emissions scenario , an average rate of global mean sea level rise of about 6 cm per decade over the next century ( with an uncertainty range of 3 -- 10 cm per decade ) , mainly due to thermal expansion of the oceans and the melting of some land ice .

It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide . A GWP is calculated over a specific time interval , commonly 20 , 100 , or 500 years . GWP is expressed as a factor of carbon dioxide ( whose GWP is standardized to 1 ) .

User related choices such as the time horizon can greatly affect the numerical values obtained for carbon dioxide equivalents . For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph . Because the GWP of a greenhouse gas depends directly on its infrared spectrum , the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change .", "qid": "615", "docid": "Global_warming_potential", "rank": 22, "score": 129331 }, { "content": "Title: Greenhouse gas emissions by the United States Content: According to the U.S. Environmental Protection Agency ( EPA ) , the United States produced 6,587 million metric tonnes of carbon-dioxide equivalent greenhouse gas ( GHG ) emissions in 2015 .

Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities . In situations where large amounts of flammable liquids and gases are contained under pressure , leaks also increase the risk of fire and explosion . Leaks from pressurized process equipment generally occur through valves , pipe connections , mechanical seals , or related equipment . Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks . Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks , fugitive emissions can be a significant proportion of total emissions . Though the quantities of leaked gases may be small , gases that have serious health or environmental impacts can cause a significant problem . To minimize and control leaks at process facilities operators carry out regular leak detection and repair activities . Routine inspections of process equipment with gas detectors can be used to identify leaks and estimate the leak rate in order to decide on appropriate corrective action . Proper routine maintenance of equipment reduces the likelihood of leaks . Because of the technical difficulties and costs of detecting and quantifying actual fugitive emissions at a site or facility , and the variability and intermittent nature of emission flow rates , bottom-up estimates based on standard emission factors are generally used for annual reporting purposes . New technologies are under development that could revolutionize the detection and monitoring of fugitive emissions . One technology , known as differential absorption lidar ( DIAL ) , can be used to remotely measure concentration profiles of hydrocarbons in the atmosphere up to several hundred meters from a facility . DIAL has been used for refinery surveys in Europe for over 15 years . A pilot study carried out in 2005 using DIAL found that actual emissions at a refinery were fifteen times higher than those previously reported using the emission factor approach . The fugitive emissions were equivalent to 0.17 % of the refinery throughput . Portable gas leak imaging cameras are also a new technology that can be used to improve leak detection and repair , leading to reduced fugitive emissions . The cameras use infrared imaging technology to produce video images in which invisible gases escaping from leak sources can be clearly identified .", "qid": "615", "docid": "Fugitive_emissions", "rank": 41, "score": 121344 }, { "content": "Title: Special Report on Emissions Scenarios Content: The Special Report on Emissions Scenarios ( SRES ) is a report by the Intergovernmental Panel on Climate Change ( IPCC ) that was published in 2000 .

It was launched in 2005 to fight Global warming and is a major pillar of EU climate policy . As of 2013 , the EU ETS covers more than 11,000 factories , power stations , and other installations with a net heat excess of 20 MW in 31 countries -- all 28 EU member states plus Iceland , Norway , and Liechtenstein . In 2008 , the installations regulated by the EU ETS were collectively responsible for close to half of the EU 's anthropogenic emissions of CO2 and 40 % of its total greenhouse gas emissions . Under the ` cap and trade ' principle , a maximum ( cap ) is set on the total amount of greenhouse gases that can be emitted by all participating installations . ` Allowances ' for emissions are then auctioned off or allocated for free , and can subsequently be traded . Installations must monitor and report their CO2 emissions , ensuring they hand in enough allowances to the authorities to cover their emissions . If emission exceeds what is permitted by its allowances , an installation must purchase allowances from others . Conversely , if an installation has performed well at reducing its emissions , it can sell its leftover credits . This allows the system to find the most cost-effective ways of reducing emissions without significant government intervention . The scheme has been divided into a number of `` trading periods '' . The first ETS trading period lasted three years , from January 2005 to December 2007 . The second trading period ran from January 2008 until December 2012 , coinciding with the first commitment period of the Kyoto Protocol . The third trading period began in January 2013 and will span until December 2020 . Compared to 2005 , when the EU ETS was first implemented , the proposed caps for 2020 represents a 21 % reduction of greenhouse gases . This target has been reached 6 years early as emissions in the ETS fell to 1812 mln tonnes in 2014 . The EU ETS has seen a number of significant changes , with the first trading period described as a ` learning by doing ' phase . Phase III sees a turn to auctioning a majority of permits rather than allocating freely ; harmonisation of rules for the remaining allocations ; and the inclusion of other greenhouse gases , such as nitrous oxide and perfluorocarbons . In 2012 , the EU ETS was also extended to the airline industry , though this has been paused for one year given the possibility of a global system for these emissions . The price of EU ETS carbon credits has been lower than intended , with a large surplus of allowances , in part because of the impact of the recent economic crisis on demand . In 2012 , the Commission said it would delay the auctioning of some allowances . Currently legislation is under way which would introduce a Market Stability Reserve to the EU ETS that adjusts the annual supply of CO2 permits based on the CO2 permits in circulation . Overall , since its conception , the EU ETS has been characterized by relatively high levels of policy uncertainty . This uncertainty has been both technical , in terms of its detailed rules and procedures , and political , in terms of its public , industry , and governmental support .

There are two conflicting ways of measuring GHG emissions : production-based ( sometimes referred to as territorial-based ) or consumption-based . Production-based emissions take place `` within national territory and offshore areas over which the country has jurisdiction '' . Consumption-based emissions encompass those emissions from domestic final consumption and those caused by the production of its imports . This means the importing country takes responsibility for emissions related to production of the exporting country 's exports . By these definitions production-based emissions include exports but exclude imports and emissions embodied in international trade , whereas consumption-based emissions refer to the reverse ( Table 1 ) . Which technique is applied by policymakers is fundamental as each can generate a very different NEI . Different NEIs would result in a country 's choosing different optimal mitigation activities , the wrong choice based on wrong information being potentially damaging .

It is named after an indicator genus , the alpine-tundra wildflower Dryas octopetala . Leaves of Dryas octopetala are occasionally abundant in the Late Glacial , often minerogenic-rich , like the lake sediments of Scandinavian lakes . The Younger Dryas saw a sharp decline in temperature over most of the northern hemisphere , at the end of the Pleistocene epoch , immediately before the current warmer Holocene . It was the most recent and longest of several interruptions to the gradual warming of the Earth 's climate since the severe Last Glacial Maximum , c. 27,000 to 24,000 calendar years BP . The change was relatively sudden , taking place in decades , and resulted in a decline of 2 to 6 degrees Celsius , advances of glaciers and drier conditions , over much of the temperate northern hemisphere . It is thought to have been caused by a decline in the strength of the Atlantic meridional overturning circulation , which transports warm water from the equator towards the North Pole , and which in turn is thought to have been caused by an influx of fresh cold water from North America into the Atlantic . The Younger Dryas was a period of climatic change , but the effects were complex and variable . In the southern hemisphere , and some areas of the north such as southeastern North America , there was a slight warming . The presence of a distinct cold period at the end of the Late Glacial interval has been known for a long time . Paleobotanical and lithostratigraphic studies of Swedish and Danish bog and lake sites , e.g. the Allerød clay pit in Denmark , first recognized and described the Younger Dryas . The Younger Dryas is the youngest and longest of three stadials that resulted from typically abrupt climatic changes that took place over the last 16,000 calendar years . Within the Blytt-Sernander classification of north European climatic phases , the prefix ` Younger ' refers to the recognition that this original ` Dryas ' period was preceded by a warmer stage , the Allerød oscillation , which in turn was preceded by the Older Dryas around 14,000 calendar years BP . This is not securely dated , and estimates vary by 400 years , but it is generally accepted that it lasted around 200 years . In northern Scotland the glaciers were thicker and more extensive than during the Younger Dryas . The Older Dryas , in turn , is preceded by another warmer stage , the Bølling oscillation that separates it from a third and even older stadial . This stadial is often , but not always , known as the Oldest Dryas . The Oldest Dryas occurred approximately 1,770 calendar years before the Younger Dryas and lasted about 400 calendar years .

ATES is applied to provide heating and cooling to buildings . Storage and recovery of thermal energy is achieved by extraction and injection of groundwater from aquifers using groundwater wells . Systems commonly operate in a seasonal mode . The groundwater that is extracted in summer , is used for cooling by transferring heat from the building to the groundwater by means of a heat exchanger . Subsequently , the heated groundwater is injected back into the aquifer , which creates a storage of heated groundwater . In wintertime , the flow direction is reversed such that the heated groundwater is extracted and can be used for heating ( often in combination with a heat pump ) . Therefore , operating an ATES system uses the subsurface as a temporal storage to buffer seasonal variations in heating and cooling demand . When replacing traditional fossil fuel dependent heating and cooling systems , ATES can serve as a cost-effective technology to reduce the primary energy consumption of a building and the associated CO2 emissions . In 2009 United Nations Climate Change Conference in Copenhagen , Denmark , many countries and regions have made targets for global climate protection . The European Union also set a target to reduce greenhouse gas emissions , increase use of sustainable energy and improve energy efficiency . For this target , ATES can actually contribute significantly , as about 40 % of global energy consumption is done by buildings , and is mainly for heating and cooling . Therefore , the development of ATES has been paid a lot of attention and the number of ATES has increased dramatically , especially in Europe . For example , in the Netherlands , it was estimated that about 20,000 ATES systems could be achieved by 2020 . This can yield a CO2 emission reduction of about 11 % , for the target of the Netherlands . Besides the Netherlands , Belgium , Germany , Turkey , and Sweden are also increasing the application of ATES .

Most of the key REDD + decisions were completed by 2013 , with the final pieces of the rulebook finished in 2015 . In the last two decades , various studies estimate that land use change , including deforestation and forest degradation , accounts for 12-29 % of global greenhouse gas emissions . For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC . During the negotiations for the Kyoto Protocol , and then in particular its Clean Development Mechanism ( CDM ) , the inclusion of tropical forest management was debated but eventually dropped due to anticipated methodological difficulties in establishing -- in particular -- additionality and leakage ( detrimental effects outside of the project area attributable to project activities ) . What remained on forestry was `` Afforestation and Reforestation '' , sectoral scope 14 of the CDM . Under this sectoral scope areas of land that had no forest cover since 1990 could be replanted with commercial or indigenous tree species . In its first eight years of operation 52 projects had been registered under the `` Afforestation and Reforestation '' scope of the CDM .

The United States also measures and reports on the net greenhouse gas sequestration in its forests .

The covering of much of the Sahara desert by grasses, trees and lakes was caused by changes in Earth's orbit around the Sun; changes in vegetation and dust in the Sahara which strengthened the African monsoon; and increased greenhouse gases, which may imply that anthropogenic global warming could result in a shrinkage of the Sahara desert. During the preceding last glacial maximum, the Sahara contained extensive dune fields and was mostly uninhabited. It was much larger than today, but its lakes and rivers such as Lake Victoria and the White Nile were either dry or at low levels. The humid period began about 14,600–14,500 years ago at the end of Heinrich event 1, simultaneously to the Bølling-Allerød warming. Rivers and lakes such as Lake Chad formed or expanded, glaciers grew on Mount Kilimanjaro and the Sahara retreated. Two major dry fluctuations occurred; during the Younger Dryas and the short 8.2 kiloyear event. The African humid period ended 6,000–5,000 years ago during the Piora Oscillation cold period. While some evidence points to an end 5,500 years ago, in the Sahel, Arabia and East Africa the period appears to have taken place in several steps such as the 4.2 kiloyear event.

They lived as hunter-gatherers until the agricultural revolution and domesticated cattle, goats and sheep. They left archeological sites and artifacts such as one of the oldest ships in the world, and rock paintings such as those in the Cave of Swimmers and in the Acacus Mountains. Earlier humid periods in Africa were postulated after the discovery of these rock paintings in now-inhospitable parts of the Sahara.

Nonpoint source pollution generally results from land runoff , precipitation , atmospheric deposition , drainage , seepage , or hydrological modification ( rainfall or snowmelt ) where tracing the pollution back to a single source is difficult . Non-point source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river , or wind-borne debris blowing out to sea . Non-point source air pollution affects air quality from sources such as smokestacks or car tailpipes . Although these pollutants have originated from a point source , the long-range transport ability and multiple sources of the pollutant make it a non-point source of pollution . Non-point source pollution can be contrasted with point source pollution , where discharges occur to a body of water or into the atmosphere at a single location . NPS may derive from many different sources with no specific solution may change to rectify the problem , making it difficult to regulate .

Studied by glaciologists , the temporal coincidence of glacier retreat with the measured increase of atmospheric greenhouse gases is often cited as an evidentiary underpinning of global warming . Mid-latitude mountain ranges such as the Himalayas , Alps , Rocky Mountains , Cascade Range , and the southern Andes , as well as isolated tropical summits such as Mount Kilimanjaro in Africa , are showing some of the largest proportionate glacial losses . Glacier mass balance is the key determinant of the health of a glacier . If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance ; if the accumulation is less than the ablation , the glacier will retreat . Glaciers in retreat will have negative mass balances , and if they do not find an equilibrium between accumulation and ablation , will eventually disappear . The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the present . Subsequently , until about 1940 , glaciers around the world retreated as the climate warmed substantially . Glacial retreat slowed and even reversed temporarily , in many cases , between 1950 and 1980 as global temperatures cooled slightly . Since 1980 , a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous , so much so that some glaciers have disappeared altogether , and the existences of many of the remaining glaciers are threatened . In locations such as the Andes of South America and Himalayas in Asia , the demise of glaciers in these regions has the potential to affect water supplies in those areas . The retreat of mountain glaciers , notably in western North America , Asia , the Alps and tropical and subtropical regions of South America , Africa and Indonesia , provide evidence for the rise in global temperatures since the late 19th century .

Snowbelts are typically found downwind of the lakes , principally off the eastern and southern shores .

The lakes produce snowsqualls and persistently cloudy skies throughout the winter months , as long as air temperatures are colder than water temperatures , or until a lake freezes over . In the United States , snowbelts are located southeast of Lake Erie from Cleveland , Ohio , to Buffalo , New York , and south of Lake Ontario stretching roughly from Rochester , New York , to Utica , New York , and northward to Watertown , New York . Other snowbelts are located on the eastern shore of Lake Michigan from Gary , Indiana , northward through Western Michigan and Northern Michigan to the Straits of Mackinac , and on the eastern and southern shores of Lake Superior from northwest Wisconsin through the northern half of the Upper Peninsula of Michigan .

Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation . In some areas , policies designed to address global warming may contribute positively towards other development objectives .

Part of this radiation is directed towards the surface , warming it . The downward component of this radiation -- that is , the strength of the greenhouse effect -- will depend on the atmosphere 's temperature and on the amount of greenhouse gases that the atmosphere contains . On Earth , the atmosphere is warmed by absorption of infrared thermal radiation from the underlying surface ( heated by the sun ) , absorption of shorter wavelength radiant energy from the sun , and convective heat fluxes from the surface . Greenhouse gases in the atmosphere radiate energy , some of which is directed to the surface and lower atmosphere . The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect . Earth 's natural greenhouse effect is critical to supporting life . Human activities , primarily the burning of fossil fuels and clearing of forests , have intensified the natural greenhouse effect , causing global warming .

Freshets occur with generally diminishing strength and duration depending upon the snowpacks having large accumulations and then the local average rates of warming temperatures ; late spring melts allowing faster flooding from the relatively longer days and higher solar angle against more southerly latitudes and elevations reaching average melting temperatures sooner where earlier and generally lesser seasonal snow piles melt more gradually spread over a longer melt period . Serious flooding from southern freshets are more often related to rain storms of large tropical weather systems rolling in from the South Atlantic or Gulf of Mexico , to add their powerful heating capacity to lesser snow packs . Tropically induced rainfall influenced quick melts can also affect snow cover to latitudes as far north as southern Canada , so long as the generally colder air mass is not blocking northward movement of low pressure systems .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change .

Climate change may cause variations in both temperature and snowfall , causing changes in the surface mass balance . Changes in mass balance control a glacier 's long-term behavior and are the most sensitive climate indicators on a glacier . From 1980 -- 2012 the mean cumulative mass loss of glaciers reporting mass balance to the World Glacier Monitoring Service is − 16 m . This includes 23 consecutive years of negative mass balances . A glacier with a sustained negative balance is out of equilibrium and will retreat , while one with a sustained positive balance is out of equilibrium and will advance . Glacier retreat results in the loss of the low elevation region of the glacier . Since higher elevations are cooler than lower ones , the disappearance of the lowest portion of the glacier reduces overall ablation , thereby increasing mass balance and potentially reestablishing equilibrium . However , if the mass balance of a significant portion of the accumulation zone of the glacier is negative , it is in disequilibrium with the local climate . Such a glacier will melt away with a continuation of this local climate . The key symptom of a glacier in disequilibrium is thinning along the entire length of the glacier . For example , Easton Glacier ( pictured below ) will likely shrink to half its size , but at a slowing rate of reduction , and stabilize at that size , despite the warmer temperature , over a few decades . However , the Grinnell Glacier ( pictured below ) will shrink at an increasing rate until it disappears . The difference is that the upper section of Easton Glacier remains healthy and snow-covered , while even the upper section of the Grinnell Glacier is bare , melting and has thinned . Small glaciers with shallow slopes such as Grinnell Glacier are most likely to fall into disequilibrium if there is a change in the local climate . In the case of positive mass balance , the glacier will continue to advance expanding its low elevation area , resulting in more melting .

The heart of Brookings , with its orientation , is protected from this maritime flow and the warm , dry , down-sloping winds that are funneled down the coastal range into the deep Chetco River gorge can reach the coast uninfluenced by the effects of the Pacific .

A shaft of precipitation which does n't evaporate before reaching the ground is a precipitation shaft . At high altitudes the precipitation falls mainly as ice crystals before melting and finally evaporating ; this is often due to compressional heating , because the air pressure increases closer to the ground . It is very common in the desert and in temperate climates . In North America , it is commonly seen in the Western United States and the Canadian Prairies . It is also very common in the Middle East , Australia and North Africa . Virga can cause varying weather effects , because as rain is changed from liquid to vapor form , it removes heat from the air due to the high heat of vaporization of water . Precipitation falling into these cooling down drafts may eventually reach the ground . In some instances , these pockets of colder air can descend rapidly , creating a wet or dry microburst which can be extremely hazardous to aviation . Conversely , precipitation evaporating at high altitude can compressionally heat as it falls , and result in a gusty downburst which may substantially and rapidly warm the surface temperature . This fairly rare phenomenon , a heat burst , also tends to be of exceedingly dry air . Virga also has a role in seeding storm cells whereby small particles from one cloud are blown into neighboring supersaturated air and act as nucleation particles for the next thunderhead cloud to begin forming .

Weathering occurs in situ ( on site ) , that is , in the same place , with little or no movement , and thus should not be confused with erosion , which involves the movement of rocks and minerals by agents such as water , ice , snow , wind , waves and gravity and then being transported and deposited in other locations . Two important classifications of weathering processes exist -- physical and chemical weathering ; each sometimes involves a biological component . Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions , such as heat , water , ice and pressure . The second classification , chemical weathering , involves the direct effect of atmospheric chemicals or biologically produced chemicals also known as biological weathering in the breakdown of rocks , soils and minerals . While physical weathering is accentuated in very cold or very dry environments , chemical reactions are most intense where the climate is wet and hot . However , both types of weathering occur together , and each tends to accelerate the other . For example , physical abrasion ( rubbing together ) decreases the size of particles and therefore increases their surface area , making them more susceptible to rapid chemical reactions . The various agents act in concert to convert primary minerals ( feldspars and micas ) to secondary minerals ( clays and carbonates ) and release plant nutrient elements in soluble forms . The materials left over after the rock breaks down combined with organic material creates soil . The mineral content of the soil is determined by the parent material ; thus , a soil derived from a single rock type can often be deficient in one or more minerals needed for good fertility , while a soil weathered from a mix of rock types ( as in glacial , aeolian or alluvial sediments ) often makes more fertile soil .

No one could keep warm , and many businesses shut down temporarily . When warm weather returned , the ice thawed and flooding was severe in most low-lying areas . Beginning on 21 January 1947 , the UK experienced several cold spells that brought large drifts of snow to the country , blocking roads and railways . It was harder to bring coal to the electric power stations . Many had to shut down , forcing severe restrictions to cut power consumption , including restricting domestic electricity to 19 hours per day and cutting industrial supplies completely . In addition , radio broadcasts were limited , television services were suspended , some magazines were ordered to stop being published and newspapers were cut in size . These measures badly affected public morale and turned the Minister of Fuel and Power , Emanuel Shinwell , into a scapegoat ; he received death threats and had to be placed under police guard .

Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth . It provides suitable conditions for many types of ecosystems , as well as water for hydroelectric power plants and crop irrigation . The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts . If enough moisture and upward motion is present , precipitation falls from convective clouds ( those with strong upward vertical motion ) such as cumulonimbus ( thunder clouds ) which can organize into narrow rainbands . In mountainous areas , heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains . On the leeward side of mountains , desert climates can exist due to the dry air caused by downslope flow which causes heating and drying of the air mass . The movement of the monsoon trough , or intertropical convergence zone , brings rainy seasons to savannah climes . The urban heat island effect leads to increased rainfall , both in amounts and intensity , downwind of cities .

It is not to be confused with a type of out in baseball , though a baseball game can be rained out . Delays due to other forms of weather are named `` snow delay '' , `` lightning delay '' , `` thunderstorm delay '' , or `` fog delay '' , while there are many other effects of weather on sport . Also , a night game can be delayed if the floodlight system fails . Often spectators will be issued a ticket for a make up event , known as a `` rain check '' . Sports typically stopped due to the onset of rain include baseball , golf , tennis , and cricket , where even slightly damp conditions in the latter three sports seriously affect playing quality and the players ' safety . In the case of tennis , several venues ( such as those of Wimbledon and the Australian Open ) have built retractable roofs atop their existing courts and stadiums in the last decade to avert rain delays that could push a tournament further than the final date . Association football generally plays on through rain , although matches can be abandoned if the pitch becomes severely waterlogged or there is lightning in the area , with the latter case being more for the protection of spectators within the metal stands surrounding stadiums . In NCAA play , should lightning be detected by any pitch official , a minimum 30-minute delay and a potential `` rainout '' can be declared if the lightning continues for a considerable amount of time under the NCAA 's all-sports policy regarding lightning . In North America , the only one of the four major sports to stop play due to rain is baseball . American football plays through all types of weather except lightning and hurricanes ( the former being more in concern to the safety of the fans sitting upon metal grandstand seating than the players ) , while basketball and hockey usually play indoors ( with some exceptions such as the Winter Classic ) , although those sports have seen event cancellations or delays due to moisture on a basketball court making safe play impossible , or a malfunction in the rink ice system of an arena causing indoor fog , along with external factors such as snowstorms or flooding preventing safe access to venues . There have also been stoppages in auto racing events like the Indianapolis 500 due to rain . If there is severe rain during a match , it can become a point of controversy whether a match should be abandoned .

They should be designed for specific soils and climates . The purpose of a rain garden is to improve water quality in nearby bodies of water and to ensure that rainwater becomes available for plants as groundwater rather than being sent through stormwater drains straight out to sea . Rain gardens can cut down on the amount of pollution reaching creeks and streams by up to 30 % . Native and adapted plants are recommended for rain gardens because they are more tolerant of the local climate , soil , and water conditions ; have deep and variable root systems for enhanced water infiltration and drought tolerance ; habitat value and diversity for local ecological communities ; and overall sustainability once established . There can be trade-offs associated with using native plants , including lack of availability for some species , late spring emergence , short blooming season , and relatively slow establishment . The plants -- a selection of wetland edge vegetation , such as wildflowers , sedges , rushes , ferns , shrubs and small trees -- take up excess water flowing into the rain garden . Water filters through soil layers before entering the groundwater system .

The case revolved around whether the Bureau of Reclamation had the authority to use water to assist the minnow when this might affect delivery of water under contract to existing users . The case was effectively settled in favor of the conservationists in 2003 . The United States Court of Appeals for the Tenth Circuit stated that provision of water for fish and wildlife is a beneficial use of the water resources , and the Bureau of Reclamation could and should act to assist the minnow .

The river begins at Lake Chapala and continues roughly north-west through the Sierra Madre Occidental , receiving the Verde , Juchipila , Bolaños , and other tributaries . At La Yesca , the La Yesca Dam was completed in 2012 and the El Cajón Dam was completed downstream in 2007 . Below El Cajón , the Aguamilpa Dam was completed in 1993 , creating a reservoir covering a large part of the territory of the municipality of El Nayar in Nayarit . From Aguamilpa , the river descends to the coastal lowlands , passing by Santiago Ixcuintla and empties into the Pacific Ocean , 16 km northwest of San Blas , in Nayarit . The river is viewed by some sources as a continuation of the Lerma River , which flows into Lake Chapala . Mexico possesses a small percentage of the world 's freshwater reserve , 0.1 % . According to an article named Water use ( and abuse ) and its effects on the crater-lake Valle de Santiago , Mexico `` most Mexican lakes are in an advanced state of desiccation or senescence , with volumes and surface area greatly reduced because of human activities '' ( page 145 ) . Some examples of these damaging activities are wood cutting , inflow diversion for agriculture , groundwater over extraction , pollution and eutrophication . Together Rio Lerma Santiago is a little over 600 miles long , but alone Rio Santiago is reported to be 269 miles long . It is an extension of the Lerma River , which at 466 miles long it is one of Mexico 's longest rivers . The water begins in the Mexican Plateau in Mexico City . Then travels westward and goes through the Lerma River , and empties in Lake Chapala , near Guadalajara . From there the water flows southward through Rio Santiago and dissipates to the Pacific Ocean near San Blas , in Nayarit . According to an article named Impacts from contamination of the Santiago River on the well-being of the inhabitants of El Salto , Jalisco the river passes by `` Ocotlán , Poncitlán , Atequiza , Atotonilquillo , Juanacatlán , , El Salto , Tonalá among others '' ( Gonzalez and Hernandez , page 711 ) . Less than 50 years ago the river was once a place to fish , bathe , and swim . It is now a river full of pollutants , with a smell that can only be described as worse than rotten eggs . This river is not the most polluted river ever but it is one of the worst polluted in Mexico . It does n't only hurt locals , but all of Mexico which rely on the river for water supply and food . Up until the 1980s this river was a beautiful place to live and visit . Luz Moreno remembers when she was a little girl playing and swimming in the river . `` Many tourists came not only from Mexico but from the US to see the falls ( El Salto Falls ) '' Moreno says `` which at one time ... I am not sure if they still do ... powered the factories '' . Concepcion Garcia , who still lives near the river , also remembers a time when you could eat the fish from the river `` People would fish and bring it home to cook and serve . I ca n't imagine that happening anymore '' . `` It was probably until the 80s when we stopped playing in the river '' Moreno says . That 's when Moreno claims that the river was rerouted to serve the bigger cities and stopped the flow in her own hometown . `` The water stayed still and was not very deep ... the factories made it worse by dumping all of their sewage water in . The water no longer flowed and cleaned itself it just sat there getting worse '' Moreno remembers . On a bad day in Garcia 's home , with the wind blowing her way , you can smell what can only be described as rotten eggs caused by the river . `` The smell is indescribable , but I know it 's because of the river '' Garcia says . Locals also think that the river causes cancer . `` I know that the river causes cancer . We did n't have a problem before the river stopped flowing ... All of the sudden the river stops flowing and then we have all of these problems with cancer among the locals '' ( Garcia ) . While no official studies have been done to connect cancer to living next to the river , the locals are convinced , and whenever someone gets cancer they blame it on the polluted river . According to Gonzalez and Hernandez the University of Guadalajara had conducted studies where they found `` fecal coliform levels 110 times above the recommended limit and lead concentrations , zinc , ammonia and phosphate threatening animal and plant life '' ( page 712 ) which is partially the governments fault for not regulating the things dumped in the river . Locals would like their river back to its former glory , but that day seems very far away and most locals do n't know where to start . Many people ask why this river is so polluted . It 's a combination of factory sewage dumping such as pulp and paper mills and leather processing plants . We can also blame this on petrochemical dumping and local farms that have dumped fertilizers and chemicals introduced by meat and dairy . If you look further most of the polluting is done by the big factories that have resided on both sides of the river , but some can also be blamed on locals . Farmers mostly have contributed to the contamination of their beloved river . In my opinion it all boils down to lack of education and regulations . Maybe if the Mexican government had put in more thought ( and money ) in to the future and cleaning of the river it would n't be that as horrible as it is today . Many locals blame the factories `` there were so many factories ... they would make all kinds of things ... Levis the jean company was once there , Hershey 's was there , I worked there for a while , and they would all dump into a river that did n't flow '' ( Garcia ) . The thing that locals fail to realize is that they are also part of the problem . Not only do the locals work in these factories , the ones who do n't ( farmers ) also dump into the river . I am not saying that the factory workers should quit their factory jobs and not support their families , but to educate themselves on what they are doing for a living and how it effects the environment . In February 2008 an eight-year-old boy , Miguel Angel Lopez Rocha , died after he fell into the river . Rocha fell near the El Salto Falls , where not that long ago tourists came from all over the world to see the falls . He died nineteen days after he fell into the river . One autopsy indicated heavy metal poison was the reason for his death . This even brought attention to one of Mexico 's worst environmental disasters . `` When Miguel died , an invisible problem became visible '' said Maria Gonzalez from the Mexican Institute for Community Development . After the unfortunate incident many locals organized a group called `` A Leap of Life '' . According to Gonzalez and Hernandez `` this made it possible to carry out the Second National Assembly Environmentally Affected by the end of May 2009 in El Salto '' ( 713 ) . Their goal is to join the national movement that brings together communities and organizational . `` They are struggling to defend their resources , the right to health and to a healthy environment '' ( Gonzalez and Hernandez , page 713 ) . Since Gonzalez and Hernandez 's article was published in 2009 , they did n't get to mention that the National Commission for Human Health tried to declare the area of El Salto an Emergency Zone . They failed because the Secretary of Environment and Natural Resources refused , he feared it would hurt the economy . Also , in the past decade the National Water Commission has not reported a single fine for illegal discharge of chemical waste into the river . When something of this magnitude happens you expect your government to help or regulate the problem , but instead it is up to the locals to try and convince the government to spend their money to save the river . This environmental disaster not only effects humans , but animals as well . Just like all food chains there is always a predator and its prey . Whatever the prey eats , it will effects the predator . Rio Santiago used to be a river thriving with fish . These fish were then eaten by other animals or by humans . If the fish are contaminated then the predators ( humans and other animals ) are most likely going to be negatively affected . `` In the 1980s , when things started to get bad , people stopped fishing , and had to find some other way to find food . A tradition that had been passed down from generation to generation got tossed away after a couple of years '' ( Garcia ) . When one part of the food chain goes away the system has to find a new way to arrange itself to satisfy everyone . Many things contributed to the pollution in Rio Santiago . Some say it is big corporate factories and businesses that should clean it up because it was their fault . Others say it was the locals who contaminated the lake . The thing is that whatever way the river got contaminated , the fact of the matter is that it needs to be cleaned up , and people need to be educated on how to properly dispose of their waste . It is also up to the government to constantly regulate and punish anyone who violates the regulations . The fact of the matter is that whichever way the river got contaminated in the first place it is everyone 's job to help clean up and to respect what mother nature has given us , because we might not get another chance .

In particular , the unequal distribution of water resources and population across the state and especially across the great continental divide was publicized . Since that time , drought and increasing competition for limited water resources has led to a critical public policy debate and raised the profile of the River District .

The 1450 mi river drains an expansive , arid watershed that encompasses parts of seven U.S. and two Mexican states . Starting in the central Rocky Mountains in the U.S. , the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona -- Nevada border , where it turns south toward the international border . After entering Mexico , the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora . Known for its dramatic canyons , whitewater rapids , and eleven U.S. National Parks , the Colorado River system is a vital source of water for 40 million people in southwestern North America . The river and its tributaries are controlled by an extensive system of dams , reservoirs , and aqueducts , which in most years divert its entire flow for agricultural irrigation and domestic water supply . Its large flow and steep gradient are used for generating hydroelectric power , and its major dams regulate peaking power demands in much of the Intermountain West . Intensive water consumption has dried up the lower 100 mi of the river , which has rarely reached the sea since the 1960s . Beginning with small bands of nomadic hunter-gatherers , Native Americans have inhabited the Colorado River basin for at least 8,000 years . Between 2,000 and 1,000 years ago , the river and its tributaries fostered large agricultural civilizations -- some of the most sophisticated indigenous cultures in North America -- which eventually faded due to a combination of severe drought and poor land use practices . Most native peoples that inhabit the basin today are descended from other groups that settled in the region beginning about 1,000 years ago . Europeans first entered the Colorado Basin in the 16th century , when explorers from Spain began mapping and claiming the area , which later became part of Mexico upon its independence in 1821 . Early contact between Europeans and Native Americans was generally limited to the fur trade in the headwaters and sporadic trade interactions along the lower river . After most of the Colorado River basin became part of the U.S. in 1846 , the bulk of the river 's course was still the subject of myths and speculation . Several expeditions charted the Colorado in the mid-19th century -- one of which , led by John Wesley Powell , was the first to run the rapids of the Grand Canyon . American explorers collected valuable information that was later used to develop the river for navigation and water supply . Large-scale settlement of the lower basin began in the mid - to late-19th century , with steamboats providing transportation from the Gulf of California to landings along the river that linked to wagon roads to the interior . Lesser numbers settled in the upper basin , which was the scene of major gold strikes in the 1860s and 1870s . Large engineering works began around the start of the 20th century , with major guidelines established in a series of international and U.S. interstate treaties known as the `` Law of the River '' . The U.S. federal government was the main driving force behind the construction of dams and aqueducts , although many state and local water agencies were also involved . Most of the major dams were built between 1910 and 1970 ; the system keystone , Hoover Dam , was completed in 1935 . The Colorado is now considered among the most controlled and litigated rivers in the world , with every drop of its water fully allocated . The environmental movement in the American Southwest has opposed the damming and diversion of the Colorado River system because of detrimental effects on the ecology and natural beauty of the river and its tributaries . During the construction of Glen Canyon Dam , environmental organizations vowed to block any further development of the river , and a number of later dam and aqueduct proposals were defeated by citizen opposition .

The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise .

The father 's behaviour is also cold because he is shooting birds and killing them . The father 's inability to understand his son is symbolically expressed by the layer of ice separating him from nature ( he is helpless on the icy surface ) ; the same helplessness applies to his relationship to his son . c ) Interdependence between theme and point of view The theme focuses on the misunderstanding between father and son , which is disastrous for the son due to the lack of knowledge as far as the different scales are concerned . The failure in communication leads to the son ´ s being afraid of dying . This is why Hemingway chooses the first person narrator with a limited point of view . He is therefore confined to presenting mere observations and suppositions . `` The boy was evidently holding tight onto himself about something '' , which is only one example of the father ´ s suppositions . The father is only an observer of the scene without realizing the son ´ s fears . He remains detached and can not imagine and feel the son ´ s distress . An observer narrator is the best way of expressing this distance between the two .

Rainfall in southwestern Australia has decreased by 10 -- 20 % since the 1970s , while southeastern Australia has also experienced a moderate decline since the 1990s . Rainfall patterns are expected to be problematic , as rain has become heavier and infrequent , as well as more common in summer rather than in winter , with little or no uptrend in rainfall in the Western Plateau and the Central Lowlands of Australia .

The degree Celsius ( ° C ) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval , a difference between two temperatures or an uncertainty . Before being renamed to honour Anders Celsius in 1948 , the unit was called centigrade , from the Latin centum , which means 100 , and gradus , which means steps .

Temperatures frequently rise above 46 ° C between May and August , and the minimum average temperature of 2 ° C occurs during December and January . The annual rainfall averages about seven inches , falling mainly during July and August . The southwesterly monsoon wind begins to blow in mid-February and continues until the end of September , whereas the cool northerly wind blows during the winter months from October to January . Sindh lies between the two monsoons -- the southwest monsoon from the Indian Ocean and the northeast or retreating monsoon , deflected towards it by the Himalayan mountains -- and escapes the influence of both . The average rainfall in Sindh is only 6 - per year . The region 's scarcity of rainfall is compensated by the inundation of the Indus twice a year , caused by the spring and summer melting of Himalayan snow and by rainfall in the monsoon season . These natural patterns have recently changed somewhat with the construction of dams and barrages on the Indus River . Parts of southeastern Sindh receive rainfall of up to 36 in and some cities have received very heavy rainfall on occasion . In 2005 , Hyderabad received 14.4 in in just 11 hours . Sindh is divided into three climatic regions : Siro ( the upper region , centred on Jacobabad ) , Wicholo ( the middle region , centred on Hyderabad ) , and Lar ( the lower region , centred on Karachi ) . The thermal equator passes through upper Sindh , where the air is generally very dry . The highest temperature ever recorded in Sindh was 53.5 C , which was recorded in Mohenjo-daro on 26 May 2010 . It was not only the hottest temperature ever recorded in Pakistan but also the hottest reliably measured temperature ever recorded in the continent of Asia and the fourth highest temperature ever recorded on earth .

Because of the effect , average low temperatures vary from 9.5 ° C in wintertime to 23 ° C in summertime and average high temperatures vary from 17 ° C in wintertime to 32 ° C in summertime . Though temperatures are moderated along the coasts , the situation changes in the interior , which are away from the moderating northerly winds .

West of the 100th meridian , much of the US is semi-arid to desert in the far southwestern US , and Mediterranean along the California coast . East of the 100th meridian , the climate is humid continental in the northern areas east through New England , to humid subtropical in the Gulf and South Atlantic regions . Southern Florida is tropical , as is Hawaii and the US Virgin Islands . Higher-elevation areas of the Rocky Mountains , the Wasatch , Sierra Nevada , and Cascade Range are alpine . The West Coast areas in coastal Oregon and Washington are oceanic climate . The state of Alaska , on the northwestern corner of the North American continent , is largely subarctic climate , but with a subpolar oceanic climate in the southeast ( Alaska Panhandle ) , southwestern peninsula and Aleutian Islands . The primary drivers of weather in the contiguous United States are the seasonal change in the solar angle , the migration north/south of the subtropical highs , and the seasonal change in the position of the polar jet stream . In the Northern Hemisphere summer the Subtropical high pressure systems move northward and closer to the United States mainland . In the Atlantic Ocean , the `` Bermuda High '' creates a south-southwest flow of warm , humid air over the eastern , southern and central United States - resulting in warm to hot temperatures , high humidity and occasional thunderstorm activity . In the Pacific Ocean high pressure builds toward the California coast resulting in a northwesterly airflow creating the typical sunny , dry , and stable weather conditions along the West Coast . In the Northern Hemisphere winter , the subtropical highs retreat southward . The polar jet stream ( and associated conflict zone between cold , dry air masses from Canada and warm , moist air masses from the Gulf of Mexico ) drops further southward into the United States - bringing more precipitation and periods of disturbed weather , as well as colder or mild air masses . Areas in the southern US ( Florida , the Gulf Coast , the Desert Southwest , and southern California ) however , often have more stable weather , as the polar jet stream 's impact does not usually reach that far south . Weather systems , be they high-pressure systems ( anticyclones ) , low-pressure systems ( cyclones ) or fronts ( boundaries between air masses of differing temperature , humidity and most commonly , both ) are faster-moving and more intense in the winter/colder months than in the summer/warmer months , when the belt of lows and storms generally move into southern Canada . The Gulf of Alaska is the origination area of many storms that enter the United States . Such `` North Pacific lows '' enter the US through the Pacific Northwest , then move eastward across the northern Rocky Mountains , northern Great Plains , upper Midwest , Great Lakes and New England states . Across the central states from late fall to spring , `` Panhandle hook '' storms move from the central Rockies into the Oklahoma/Texas panhandle areas , then northeast toward the Great Lakes . They generate unusually large temperature contrasts , and often bring heavy Gulf moisture northward , resulting sometimes in cold conditions and possibly-heavy snow or ice north and west of the storm track , and warm conditions , heavy rains and potentially-severe thunderstorms south and east of the storm track - often simultaneously . Across the northern states in winter usually from Montana eastward , `` Alberta clipper '' storms track east and bring light to moderate snowfalls from the Great Lakes to New England , and often , windy and severe Arctic outbreaks behind them . When winter-season Canadian cold air masses drop unusually far southward , `` Gulf lows '' can develop in or near the Gulf of Mexico , then track eastward or northeastward across the Southern states , or nearby Gulf or South Atlantic waters . They often bring rain , but on rare occasions can bring ice to areas of the interior southern states . In the cold season ( generally November to March ) , most precipitation occurs in conjunction with organized low-pressure systems and associated fronts . In the summer , storms are much more localized , with short-duration thunderstorms common in many areas east of the 100th meridian . In the warm season , storm systems affecting a large area are less frequent , and weather conditions are more solar -LCB- sun -RCB- controlled , with the greatest chance for thunderstorm and severe weather activity during peak heating hours , mostly between 3 PM and 9 PM local time . From May to August especially , often-overnight mesoscale-convective-system ( MCS ) thunderstorm complexes , usually associated with frontal activity , can deliver significant to flooding rainfall amounts from the Dakotas/Nebraska eastward across Iowa/Minnesota to the Great Lakes states .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years . Global temperatures increased by 5 -- 8 ° C . The carbon dioxide was likely released in two pulses , the first lasting less than 2,000 years . Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon . Stratigraphic sections of rock from this period reveal numerous other changes . Fossil records for many organisms show major turnovers . For example , in the marine realm , a mass extinction of benthic foraminifera , a global expansion of subtropical dinoflagellates , and an appearance of excursion , planktic foraminifera and calcareous nanofossils all occurred during the beginning stages of PETM .

The paradox is resolved by understanding temperature through its more rigorous definition as the tradeoff between energy and entropy , with the reciprocal of the temperature , thermodynamic beta , as the more fundamental quantity . Systems with a positive temperature will increase in entropy as one adds energy to the system . Systems with a negative temperature will decrease in entropy as one adds energy to the system . Most familiar systems can not achieve negative temperatures , because adding energy always increases their entropy . The possibility of decreasing in entropy with increasing energy requires the system to `` saturate '' in entropy , with the number of high energy states being small . These kinds of systems , bounded by a maximum amount of energy , are generally forbidden classically . Thus , negative temperature is a strictly quantum phenomenon .

Concern over human induced climate change through the emission of carbon dioxide from fossil fuels and methane from agriculture and industry , are driving research efforts across the state at university , state , and federals levels to understand what the implications of climate change could be in Idaho . In the big picture of greenhouse gas emissions , Idaho emits the least carbon dioxide per person of the United States , less than 23,000 pounds a year . It relies mostly on nonpolluting hydroelectric power from its rivers . Like other parts of the world , Idaho has seen significant temperature increases , especially in the last several decades .

Sinusoidal estimates of expected temperatures , for northern locales , usually place the lowest temperatures around January 23 and the highest around July 24 , and provide fairly accurate estimates of temperature expectations . Actual average temperatures in North America usually significantly differ twice over the course of the year : Mid-autumn temperatures tend to be warmer than predicted by the sinusoidal model , creating the impression of extended summer warmth known as Indian summer . For five days around January 25 , temperatures are usually significantly warmer than predicted by the sinusoidal estimate , and also warmer than neighboring temperatures on both sides . During this `` thaw '' period , usually lasting for about a week , temperatures are generally about 6 ° C ( 10 ° F ) above normal . This varies from year to year , and temperatures fluctuate enough that such a rise in late-January temperature would be unremarkable ; what is remarkable ( and unexplained ) is the tendency for such rises to occur more commonly in late January than in mid-January or early February , which sinusoidal estimates have to be slightly warmer . In some regions ( such as northern Canada ) this phenomenon will not be manifest as a `` thaw '' in the technical sense , since temperatures will remain below freezing . The January thaw is believed to be a weather singularity . A possible physical mechanism for such phenomena was offered in the 1950s by E.G. Bowen : he suggested that some `` calendaricities '' ( as he called them ) might be explicable in terms of meteoric particles from cometary orbits acting as ice nuclei in terrestrial clouds ; his theory then received some support from several sources .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years .

The severe winter led to mass unemployment and severe disruptions to shipping on the River Thames , which froze for the last time on record .

Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional : the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that `` Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely '' the highest in at least the past 1,300 years . '' The curve shown in graphs of these reconstructions is widely known as the hockey stick graph because of the sharp increase in temperatures during the last century . As of 2010 this broad pattern was supported by more than two dozen reconstructions , using various statistical methods and combinations of proxy records , with variations in how flat the pre-20th-century `` shaft '' appears . Sparseness of proxy records results in considerable uncertainty for earlier periods . Individual proxy records , such as tree ring widths and densities used in dendroclimatology , are calibrated against the instrumental record for the period of overlap . Networks of such records are used to reconstruct past temperatures for regions : tree ring proxies have been used to reconstruct Northern Hemisphere extratropical temperatures ( within the tropics trees do not form rings ) but are confined to land areas and are scarce in the Southern Hemisphere which is largely ocean . Wider coverage is provided by multiproxy reconstructions , incorporating proxies such as lake sediments , ice cores and corals which are found in different regions , and using statistical methods to relate these sparser proxies to the greater numbers of tree ring records . The `` Composite Plus Scaling '' ( CPS ) method is widely used for large-scale multiproxy reconstructions of hemispheric or global average temperatures ; this is complemented by Climate Field Reconstruction ( CFR ) methods which show how climate patterns have developed over large spatial areas , making the reconstruction useful for investigating natural variability and long-term oscillations as well as for comparisons with patterns produced by climate models .

We will be using the following equation to find out how much heat is lost by a person standing in the same room in summertime as compared to the winter , at exactly the same thermostat reading temperature : Q ̇ = εσA_s ( T_s ^ 4-T_surr ^ 4 ) Where Q ̇ is the rate of heat loss ( W ) , ε is the emissivity ( or the ability of an objects surface to emit energy by radiation ) of a person , σ is the Stefan-Boltzmann constant ( 5.670 x 10 ^ ( -8 ) W/m2 ∙ K4 ) , As is the surface area of a person , Ts is the surface temperature of a person ( K ) , and Tsurr is the surface temperature of the walls , ceiling , and floor ( K ) . Please note that this equation is only valid for an object standing in a completely enclosed room , box , etc. .

Dr. Gutzler said spring temperatures have an impact, too, with warmer air causing more snow to turn to vapor and essentially disappear.
[ { "content": "Title: Lake-effect snow Content: Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water , warming the lower layer of air which picks up water vapor from the lake , rises up through the colder air above , freezes and is deposited on the leeward ( downwind ) shores . The same effect also occurs over bodies of salt water , when it is termed ocean-effect or bay-effect snow . The effect is enhanced when the moving air mass is uplifted by the orographic influence of higher elevations on the downwind shores . This uplifting can produce narrow but very intense bands of precipitation , which deposit at a rate of many inches of snow each hour , often resulting in a large amount of total snowfall . The areas affected by lake-effect snow are called snowbelts . These include areas east of the Great Lakes , the west coasts of northern Japan , the Kamchatka Peninsula in Russia , and areas near the Great Salt Lake , Black Sea , Caspian Sea , Baltic Sea , and parts of the northern Atlantic Ocean . A lake-effect blizzard is the blizzard-like conditions resulting from lake-effect snow . Under certain conditions , strong winds can accompany lake-effect snows creating blizzard-like conditions ; however the duration of the event is often slightly less than that required for a blizzard warning in both the US and Canada . If the air temperature is low enough to keep the precipitation frozen , it falls as lake-effect snow . For lake-effect rain or snow to form , the air moving across the lake must be significantly cooler than the surface air ( which is likely to be near the temperature of the water surface ) . Specifically , the air temperature at an altitude where the air pressure is 850 mbar ( roughly 1.5 km vertically ) should be 13 ° C-change lower than the temperature of the air at the surface . Lake-effect occurring when the air at 850 mbar is much colder than the water surface can produce thundersnow , snow showers accompanied by lightning and thunder ( caused by larger amounts of energy available from the increased instability ) .", "qid": "621", "docid": "Lake-effect_snow", "rank": 1, "score": 152947 }, { "content": "Title: Impact winter Content: An impact winter is a hypothesized period of prolonged cold weather due to the impact of a large asteroid or comet on the Earth 's surface .

The main forms of precipitation include drizzle , rain , sleet , snow , graupel and hail . Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor , so that the water condenses and `` precipitates '' . Thus , fog and mist are not precipitation but suspensions , because the water vapor does not condense sufficiently to precipitate . Two processes , possibly acting together , can lead to air becoming saturated : cooling the air or adding water vapor to the air . Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud . Short , intense periods of rain in scattered locations are called `` showers . '' Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain . This process is typically active when freezing rain is occurring . A stationary front is often present near the area of freezing rain and serves as the foci for forcing and rising air . Provided necessary and sufficient atmospheric moisture content , the moisture within the rising air will condense into clouds , namely stratus and cumulonimbus . Eventually , the cloud droplets will grow large enough to form raindrops and descend toward the Earth where they will freeze on contact with exposed objects . Where relatively warm water bodies are present , for example due to water evaporation from lakes , lake-effect snowfall becomes a concern downwind of the warm lakes within the cold cyclonic flow around the backside of extratropical cyclones . Lake-effect snowfall can be locally heavy . Thundersnow is possible within a cyclone 's comma head and within lake effect precipitation bands . In mountainous areas , heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation . On the leeward side of mountains , desert climates can exist due to the dry air caused by compressional heating . The movement of the monsoon trough , or intertropical convergence zone , brings rainy seasons to savannah climes . Precipitation is a major component of the water cycle , and is responsible for depositing the fresh water on the planet . Approximately 505000 km3 of water falls as precipitation each year ; 398000 km3 of it over the oceans and 107000 km3 over land . Given the Earth 's surface area , that means the globally averaged annual precipitation is 990 mm , but over land it is only 715 mm . Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes .

Snowbelts are typically found downwind of the lakes , principally off the eastern and southern shores . Lake-effect snow occurs when cold air moves over warmer water , taking up moisture that later precipitates as snow when the air moves over land and cools . The lakes produce snowsqualls and persistently cloudy skies throughout the winter months , as long as air temperatures are colder than water temperatures , or until a lake freezes over . In the United States , snowbelts are located southeast of Lake Erie from Cleveland , Ohio , to Buffalo , New York , and south of Lake Ontario stretching roughly from Rochester , New York , to Utica , New York , and northward to Watertown , New York . Other snowbelts are located on the eastern shore of Lake Michigan from Gary , Indiana , northward through Western Michigan and Northern Michigan to the Straits of Mackinac , and on the eastern and southern shores of Lake Superior from northwest Wisconsin through the northern half of the Upper Peninsula of Michigan . Portions of the snowbelt are located in Ontario , Canada , which includes the eastern shore of Lake Superior from Sault Ste. Marie northward to Wawa , as well as the eastern and southern shores of Lake Huron and Georgian Bay from Parry Sound to London . During the winter season , north-westerly winds cause frequent road closures , with Highway 21 on the Lake Huron coast and Highway 26 south of Georgian Bay as far east as Barrie , Ontario , being strongly affected . The Niagara Peninsula and the north-eastern shores of Lake Ontario are especially hard-hit by heavy snowfall when south-western winds are predominant . Lake Erie is the second smallest of the five Great Lakes and the most shallow . It can completely freeze over during winter . Once frozen , lake-effect snow over land to the east and south of Lake Erie is temporarily alleviated . This does not end the possibility of a damaging winter storm .

As air rises from sea level to the upper regions of the atmosphere the temperature decreases .

The position of the Alps in the central European continent profoundly affects the climate of all the surrounding regions . The accumulation of vast masses of snow , which have gradually been converted into permanent glaciers , maintains a gradation of very different climates within the narrow space that intervenes between the foot of the mountains and their upper ridges ; it cools breezes that waft to the plains on either side , but its most important function is to regulate the water supply of the large region which is traversed by the streams of the Alps . Nearly all the moisture that is precipitated during fall , winter , and spring is stored in the form of snow and gradually diffused in the course of the succeeding summer ; even in the hottest and driest seasons the reserves accumulated during a long preceding period of years in the form of glaciers are available to maintain the regular flow of the greater streams .

In an address towards the U.S. Congress in June 2013 , Obama detailed a specific action plan to achieve the 17 % carbon emissions cut from 2005 by 2020 . He included such measures as shifting from coal-based power generation to solar and natural gas production . Climate change is seen as a national security threat to the United States . In 2015 , according to The New York Times and others , oil companies knew that burning oil and gas could cause global warming since the 1970s but , nonetheless , funded deniers for years . 2016 was an historic year for billion-dollar weather and climate disasters in U.S.", "qid": "621", "docid": "Climate_change_in_the_United_States", "rank": 21, "score": 113101 }, { "content": "Title: January 1987 Southeast England snowfall Content: The January 1987 snowfall was a very heavy lake-effect type snow event that affected the areas of East Anglia , South-East England and London between 11 and 14 January and was the heaviest snowfall to fall in that part of the United Kingdom since the winter of 1981/82 . Over 50 cm ( 20 inches ) of snow fell in parts of Kent , Essex , London and Surrey , with the North Downs just east of Maidstone recording 75 cm ( 30 inches ) . Parts of West Cornwall also had heavy falls . Several towns were cut off due to the heavy snowfall including the Isle of Sheppey which needed airlifts during the height of the storm . This was due to a high pressure system over Siberia that moved into Scandinavia which in turn dragged a strong easterly airflow and brought very cold temperatures across Europe and the United Kingdom . A low pressure system over Italy caused the airflow to drag the very cold air from Siberia to Western Europe and picked up further moisture from the North Sea which produced the heavy snowfall . This caused serious disruption of transport in the area including the cancellation of many train services and the closure of many roads and railway lines .

Atmospheric stability is a measure of the atmosphere 's tendency to encourage or deter vertical motion , and vertical motion is directly correlated to different types of weather systems and their severity . In unstable conditions , a lifted thing , such as a parcel of air will be warmer than the surrounding air at altitude . Because it is warmer , it is less dense and is prone to further ascent . In meteorology , instability can be described by various indices such as the Bulk Richardson Number , lifted index , K-index , convective available potential energy ( CAPE ) , the Showalter , and the Vertical totals . These indices , as well as atmospheric instability itself , involve temperature changes through the troposphere with height , or lapse rate . Effects of atmospheric instability in moist atmospheres include thunderstorm development , which over warm oceans can lead to tropical cyclogenesis , and turbulence .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions . They were preserved so well by quick freezing , which is taken as evidence of a rapid onset of a global blizzard or similar event . Interspersed with the analytical parts of the book are a series of interlinked short fictional scenarios , written in italics , describing what might transpire today if a destabilization of the North Atlantic Current were to occur .

The exact meaning of surface varies according to the measurement method used , but it is between 1 mm and 20 m below the sea surface . Air masses in the Earth 's atmosphere are highly modified by sea surface temperatures within a short distance of the shore . Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass . Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth 's oceans . Tropical cyclones can also cause a cool wake , due to turbulent mixing of the upper 30 m of the ocean . SST changes diurnally , like the air above it , but to a lesser degree . There is less SST variation on breezy days than on calm days . In addition , ocean currents such as the Atlantic Multidecadal Oscillation ( AMO ) , can effect SST 's on multi-decadal time scales , a major impact results from the global thermohaline circulation , which affects average SST significantly throughout most of the world 's oceans . Coastal SSTs can cause offshore winds to generate upwelling , which can significantly cool or warm nearby landmasses , but shallower waters over a continental shelf are often warmer . Onshore winds can cause a considerable warm-up even in areas where upwelling is fairly constant , such as the northwest coast of South America .

The reverse of deposition is sublimation and hence sometimes deposition is called desublimation .

This is how snow forms in clouds , as well as how frost and hoar frost form on the ground or other surfaces . Another example is when frost forms on a leaf . For deposition to occur , thermal energy must be removed from a gas . When the leaf becomes cold enough , water vapor in the air surrounding the leaf loses enough thermal energy to change into a solid . Even though the air temperature may be below the dew point , the water vapor may not be able to condense spontaneously if there is no way to remove the latent heat . When the leaf is introduced , the supercooled water vapor immediately begins to condense , but by this point is already past the freezing point . This causes the water vapor to change directly into a solid . Another example is the soot that is deposited on the walls of chimneys . Soot molecules rise from the fire in a hot and gaseous state . When they come into contact with the walls they cool , and change to the solid state , without formation of the liquid state . The process is made use of industrially in combustion chemical vapor deposition .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering .

While it is most common in the month of June , it can occur in surrounding months , giving rise to other colloquialisms , such as `` May Gray '' , `` No Sky July '' , and , rarely , `` Fogust '' . Low-altitude stratus clouds form over the cool water of the California Current , and spread overnight into the coastal regions of Southern California . The overcast skies often are accompanied by fog and drizzle , though usually not rain . June Gloom usually clears up between mid-morning and early afternoon , depending on the strength of the marine layer , and gives way to sunny skies . On a strong June Gloom day , the clouds and fog may extend inland to the valleys and Inland Empire and may persist into the mid-afternoon or evening . A combination of atmospheric and oceanic conditions must be just right in order for June Gloom to form , and these conditions usually align only around May and June of each year . These include the marine layer effect common to the west coast of the United States , an atmospheric inversion caused by subsidence of high-pressure air from the subtropical ridge , and sufficiently cool ocean water off the coast . The June Gloom pattern is also enhanced by the Catalina eddy local to southern California . May and June together are usually the cloudiest months in coastal Southern California . June Gloom is stronger in years associated with a La Niña , and weaker or nonexistent in years with an El Niño .

This condensation temperature depends on the volatile substance and the partial pressure of vapor in the protostar nebula . The actual temperature and distance for the snow line of water ice depend on the physical model used to calculate it and on the theoretical solar nebula model : 170 K at 2.7 AU ( Hayashi , 1981 ) 143 K at 3.2 AU to 150 K at 3 AU ( Podolak and Zucker , 2010 ) 3.1 AU ( Martin and Livio , 2012 ) ≈ 150 K for μm-size grains and ≈ 200 K for km-size bodies ( D'Angelo and Podolak , 2015 ) The radial position of the condensation/evaporation front varies over time , as the nebula evolves . Occasionally , the term snow line is also used to represent the present distance at which water ice can be stable ( even under direct sunlight ) . This current snow line distance is different from the formation snow line distance during the formation of Solar System , and approximately equals 5 AU . The reason for the difference is that during the formation of Solar System , the solar nebula was an opaque cloud where temperature were lower close to the Sun , and the Sun itself was less energetic . After formation , the ice got buried by infalling dust and it has remained stable a few meters below the surface . If ice within 5 AU is exposed , e.g. by a crater , then it sublimates on short timescales . However , out of direct sunlight ice can remain stable on the surface of asteroids ( and the Moon ) if it is located in permanently shadowed craters , where temperature may remain very low over the age of the Solar System ( e.g. 30 -- 40 K on the Moon ) . Observations of the asteroid belt , located between Mars and Jupiter , suggest that the water snow line during formation of Solar System was located within this region . The outer asteroids are icy C-class objects ( e.g. Abe et al. 2000 ; Morbidelli et al. 2000 ) whereas the inner asteroid belt is largely devoid of water . This implies that when planetesimal formation occurred the snow line was located at around 2.7 AU from the Sun . For example , the dwarf planet Ceres with semi-major axis of 2.77 AU lies almost exactly on the lower estimation for water snow line during the formation of the Solar System . Ceres appears to have an icy mantle and may even have a water ocean below the surface . Each volatile substance has its own snow line , e.g. carbon monoxide and nitrogen , so it is important to always specify which material 's snow line is meant . The lower temperature in the nebula beyond the frost line makes many more solid grains available for accretion into planetesimals and eventually planets . The frost line therefore separates terrestrial planets from giant planets in the Solar System . However , giant planets have been found inside the frost line around several other stars ( so-called hot Jupiters ) . They are thought to have formed outside the frost line , and later migrated inwards to their current positions . Earth , which lies less than a quarter of the distance to the frost line but is not a giant planet , has adequate gravitation for keeping methane , ammonia , and water vapor from escaping it . Methane and ammonia are rare in the Earth 's atmosphere only because of their instability in an oxygen-rich atmosphere that results from life forms ( largely green plants ) whose biochemistry suggests plentiful methane and ammonia at one time , but of course liquid water and ice , which are chemically stable in such an atmosphere , form much of the surface of Earth . Researchers Rebecca Martin and Mario Livio have proposed that asteroid belts may tend to form in the vicinity of the frost line , due to nearby giant planets disrupting planet formation inside their orbit . By analysing the temperature of warm dust found around some 90 stars , they concluded that the dust ( and therefore possible asteroid belts ) was typically found close to the frost line .

No one could keep warm , and many businesses shut down temporarily . When warm weather returned , the ice thawed and flooding was severe in most low-lying areas . Beginning on 21 January 1947 , the UK experienced several cold spells that brought large drifts of snow to the country , blocking roads and railways . It was harder to bring coal to the electric power stations . Many had to shut down , forcing severe restrictions to cut power consumption , including restricting domestic electricity to 19 hours per day and cutting industrial supplies completely . In addition , radio broadcasts were limited , television services were suspended , some magazines were ordered to stop being published and newspapers were cut in size . These measures badly affected public morale and turned the Minister of Fuel and Power , Emanuel Shinwell , into a scapegoat ; he received death threats and had to be placed under police guard . Towards the end of February there were also fears of a food shortage as supplies were cut off and vegetables were frozen into the ground . Mid-March brought warmer air to the country which thawed the snow lying on the ground . This snowmelt ran off the frozen ground straight into rivers and caused widespread flooding .

It may lead to phenomena such as houses feeling cooler in the winter and warmer in the summer at the same temperature . For example , in a room in which air temperature is maintained at 22 ° Celsius at all times , but in which the inner surfaces of the house is estimated to be an average temperature of 10 ° Celsius in the winter or 25 ° Celsius in the summer , heat transfer from the surfaces to the individual will occur , resulting in a difference in the perceived temperature . We can observe and compare the rate of radiation heat transfer between a person and the surrounding surfaces if we first make a few simplifying assumptions : The heat exchange in the environment is in a `` steady state '' , meaning that there is a constant flow of heat either into or out of the house . The person is completely surrounded by the interior surfaces of the room . Heat transfer by convection is not considered . The walls , ceiling , and floor are all at the same temperature . For an average person , the outer surface area is 1.4 m ² , the surface temperature is 30 ° Celsius , and the emissivity is 0.95 . Emissivity is the ability of a surface to emit radiant energy compared to that of a black body at the same temperature . We will be using the following equation to find out how much heat is lost by a person standing in the same room in summertime as compared to the winter , at exactly the same thermostat reading temperature : Q ̇ = εσA_s ( T_s ^ 4-T_surr ^ 4 ) Where Q ̇ is the rate of heat loss ( W ) , ε is the emissivity ( or the ability of an objects surface to emit energy by radiation ) of a person , σ is the Stefan-Boltzmann constant ( 5.670 x 10 ^ ( -8 ) W/m2 ∙ K4 ) , As is the surface area of a person , Ts is the surface temperature of a person ( K ) , and Tsurr is the surface temperature of the walls , ceiling , and floor ( K ) .

A shaft of precipitation which does n't evaporate before reaching the ground is a precipitation shaft . At high altitudes the precipitation falls mainly as ice crystals before melting and finally evaporating ; this is often due to compressional heating , because the air pressure increases closer to the ground . It is very common in the desert and in temperate climates . In North America , it is commonly seen in the Western United States and the Canadian Prairies . It is also very common in the Middle East , Australia and North Africa . Virga can cause varying weather effects , because as rain is changed from liquid to vapor form , it removes heat from the air due to the high heat of vaporization of water . Precipitation falling into these cooling down drafts may eventually reach the ground . In some instances , these pockets of colder air can descend rapidly , creating a wet or dry microburst which can be extremely hazardous to aviation . Conversely , precipitation evaporating at high altitude can compressionally heat as it falls , and result in a gusty downburst which may substantially and rapidly warm the surface temperature . This fairly rare phenomenon , a heat burst , also tends to be of exceedingly dry air . Virga also has a role in seeding storm cells whereby small particles from one cloud are blown into neighboring supersaturated air and act as nucleation particles for the next thunderhead cloud to begin forming .

As a consequence of the different adiabatic lapse rates of moist and dry air , the air on the leeward slopes becomes warmer than equivalent elevations on the windward slopes .

A wide variety of weather can be found along a stationary front , but usually clouds , prolonged precipitation , and storm trains are found there .

Stationary fronts will either dissipate after several days or devolve into shear lines , but can change into a cold or warm front if conditions aloft change . Additionally , if one air mass enters the other , then it will change into a cold or warm front , and the stationary front will be reclassified as moving . For instance , if a warm air mass enters a cold air mass , since the advancing air mass is warm , the stationary front will change into a warm front . A stationary front becomes a shear line when the density contrast across the frontal boundary vanishes , usually as a result of temperature equalization , while the narrow zone of wind-shift persists for a time .

The nature of the `` snow '' was initially unknown . In radar images , smooth surfaces such as lava plains generally appear dark , while rough surfaces such as impact debris appear bright . The composition of the rock also alters the radar return : conductive material , or material with a high dielectric constant , appears brighter . It was therefore initially difficult to determine whether the high-altitude areas of Venus were different from the lowlands in chemical composition or in texture . Possible explanations included loose soil , different rates of weathering at high and low elevations , and chemical deposition at high elevation . It could not be water ice , which can not exist in the extremely hot , dry conditions of the Venusian surface . Data from the radar mapper on the Pioneer Venus orbiter suggested an explanation in terms of chemical composition . It was hypothesized that the underlying rock contained iron pyrite or other metallic inclusions that would be very reflective . At the high temperatures found on the surface of Venus , these minerals would gradually evaporate . Faster weathering at high elevation might continually expose new material , causing the highlands to appear brighter than lowlands . High-resolution radar observations by the Magellan probe by 1995 began to favor the hypothesis that metallic compounds sublimate in lower , warmer altitudes and deposit in higher , cooler areas .

This mass of cold air was so strong that the temperature at Mequon , Wisconsin , dropped to − 40 ° F ( − 40 ° C ) . The previous record was − 28 ° F ( − 33 ° C ) and temperatures below − 20 ° F ( − 29 ° C ) had been felt there only six times in the previous 100 years .

Thunderstorms occur in association with a type of cloud known as a cumulonimbus . They are usually accompanied by strong winds , heavy rain , and sometimes snow , sleet , hail , or , in contrast , no precipitation at all . Thunderstorms may line up in a series or become a rainband , known as a squall line . Strong or severe thunderstorms , known as supercells , rotate as do cyclones . While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy , vertical wind shear sometimes causes a deviation in their course at a right angle to the wind shear direction . Thunderstorms result from the rapid upward movement of warm , moist air , sometimes along a front . As the warm , moist air moves upward , it cools , condenses , and forms a cumulonimbus cloud that can reach heights of over 20 km . As the rising air reaches its dew point temperature , water vapor condenses into water droplets or ice , reducing pressure locally within the thunderstorm cell . Any precipitation falls the long distance through the clouds towards the Earth 's surface . As the droplets fall , they collide with other droplets and become larger . The falling droplets create a downdraft as it pulls cold air with it , and this cold air spreads out at the Earth 's surface , occasionally causing strong winds that are commonly associated with thunderstorms . Thunderstorms can form and develop in any geographic location but most frequently within the mid-latitude , where warm , moist air from tropical latitudes collides with cooler air from polar latitudes . Thunderstorms are responsible for the development and formation of many severe weather phenomena . Thunderstorms , and the phenomena that occur along with them , pose great hazards . Damage that results from thunderstorms is mainly inflicted by downburst winds , large hailstones , and flash flooding caused by heavy precipitation . Stronger thunderstorm cells are capable of producing tornadoes and waterspouts . There are four types of thunderstorms : single-cell , multi-cell cluster , multi-cell lines , and supercells . Supercell thunderstorms are the strongest and the most associated with severe weather phenomena . Mesoscale convective systems formed by favorable vertical wind shear within the tropics and subtropics can be responsible for the development of hurricanes . Dry thunderstorms , with no precipitation , can cause the outbreak of wildfires from the heat generated from the cloud-to-ground lightning that accompanies them . Several means are used to study thunderstorms : weather radar , weather stations , and video photography .

The problem is most notable in certain realms of aviation . Carburetor icing occurs when there is humid air , and the temperature drop in the venturi causes the water vapor to freeze . The venturi effect can drop the ambient air temperature by 30-40 degrees F , therefore carburetor icing often occurs when the outside air temperature is in the 60-70 degree F range . Unfortunately , the warm air temperature often causes pilots to overlook the possibility of carb icing . The ice will form on the surfaces of the carburetor throat , further restricting it . This may increase the Venturi effect initially , but eventually restricts airflow , perhaps even causing a complete blockage of air to the carburetor . The engine begins to run more rich as ice formation increases . Without intervention ( carb heat or leaning ) this can only continue until the mixture is outside of the `` chemically correct '' range for combustion . Icing may also cause jamming of the mechanical parts of the carburetor , such as the throttle , typically a butterfly valve . While it applies to all carburetors , carburetor icing is of particular concern in association with piston-powered aircraft , especially small , single-engine , light aircraft . Aircraft powered by carbureted engines are equipped with carburetor heat systems to overcome the icing problem . In cars , carburetor icing can occasionally be a nuisance . The inlet manifold and parts of the carburetor often have warm water from the cooling system or exhaust gas circulating through them to combat this problem . Motorcycles can also suffer from carburetor icing , although some engine designs are more susceptible to it than others .

The neoglaciation has no well-marked universal beginning : local conditions and ecological inertia affected the onset of detectably cooler ( and wetter ) conditions . Driven inexorably by the Milankovitch cycle , cooler summers in higher latitudes of North America , which would cease to completely melt the annual snowfall , were masked at first by the presence of the slowly disappearing continental ice sheets , which persisted long after the astronomically calculated moment of maximum summer warmth : `` the neoglaciation can be said to have begun when the cooling caught up with the warming '' , remarked E. C. Pielou .

Whether it has been temporarily or semi-permanently stalled , neoglaciation has been marked by a retreat from the warm conditions of the Climatic Optimum and the advance or reformation of glaciers that had not existed since the last ice age .

The storms caused chaos around the country , leaving people stranded at airports , blocking state highways and resulting in entire regions , particularly Otago , being completely closed . The initial storm of July was relatively short lived , only to return again in August . The winter storm also caused mixed precipitation . The snowfall was caused by Antarctic storms which moved northward . A large high pressure system had developed and stretched from Antarctica to the subtropics , where it had then merged with three neighbouring low pressure systems , causing cold temperatures and heavy snowfall . The storms were incorrectly deemed by news reporters as `` once in a lifetime in New Zealand '' , though snow fall in the country during the winter months is quite common .", "qid": "621", "docid": "2011_New_Zealand_snowstorms", "rank": 93, "score": 99208 }, { "content": "Title: Pneumonia front Content: The term Pneumonia front , first coined by Milwaukee Weather Bureau Office in the 1960s , is used to describe a rare meteorological phenomenon observed on the western Lake Michigan , USA , shoreline during the warm season .

An energy-expensive approach . There are many other ways to beat the cold , for earlier spring planting and growing into the fall and winter : Row covers : Light fabric placed over plants retains heat and can offer up to several degrees of frost protection . In smaller gardens almost any type of cover , including newspaper cones , miscellaneous bits of plastic , etc. , can serve the same purpose . Hoop houses : Plastic sheeting is placed over a frame ( usually in an arced shape ) , to create a type of greenhouse . Hoophouses can be large or small , simple or nearly as functional as greenhouses . Cold frames : Transparent-roofed enclosure , built low to the ground , used to protect plants from cold weather . Cold frames are found in home gardens and in vegetable farming . They are most often used for growing seedlings that are later transplanted into open ground . Hotbeds : A mass of hot compost is used for the heat it gives off to warm a nearby plant . Typically a few centimeters of soil are placed on top of the compost mass , and the plant grows there , above the rising heat . Mulches : Any material placed on the soil around plants will help retain heat . Organic mulches include straw , compost , etc. . Synthetic mulches , typically , plastic sheeting with slits through which plants grow , is used extensively in large-scale vegetable growing . Raised beds : Beds where the soil has been loosened and piled a few inches to over a foot above the surrounding ground heat up more quickly in spring , allowing earlier planting . Season extension techniques are most effective when combined with crop varieties selected for the extended growing conditions . Many approaches are used in large-scale agriculture , as well as in small-scale organic farming , and home gardening .

It is considered both controversial and essential to wine production . In the physiology of the grapevine , the amount of available water affects photosynthesis and hence growth , as well as the development of grape berries . While climate and humidity play important roles , a typical grape vine needs 25-35 inches ( 635-890 millimeters ) of water a year , occurring during the spring and summer months of the growing season , to avoid stress . A vine that does not receive the necessary amount of water will have its growth altered in a number of ways ; some effects of water stress ( particularly , smaller berry size and somewhat higher sugar content ) are considered desirable by wine grape growers . In many Old World wine regions , natural rainfall is considered the only source for water that will still allow the vineyard to maintain its terroir characteristics . The practice of irrigation is viewed by some critics as unduly manipulative with the potential for detrimental wine quality due to high yields that can be artificially increased with irrigation . It has been historically banned by the European Union 's wine laws , though in recent years individual countries ( such as Spain ) have been loosening their regulations and France 's wine governing body , the Institut National des Appellations d'Origine ( INAO ) , has also been reviewing the issue . In very dry climates that receive little rainfall , irrigation is considered essential to any viticultural prospects . Many New World wine regions such as Australia and California regularly practice irrigation in areas that could n't otherwise support viticulture . Advances and research in these wine regions ( as well as some Old World wine regions such as Israel ) , have shown that potential wine quality could increase in areas where irrigation is kept to a minimum and managed . The main principle behind this is controlled water stress , where the vine receives sufficient water during the budding and flowering period , but irrigation is then scaled back during the ripening period so that the vine then responds by funneling more of its limited resources into developing the grape clusters instead of excess foliage . If the vine receives too much water stress , then photosynthesis and other important processes such as nutrient storage could be impacted with the vine essentially shutting down . The availability of irrigation means that if drought conditions emerge , sufficient water can be provided for the plant so that the balance between water stress and development is kept to optimal levels .", "qid": "622", "docid": "Irrigation_in_viticulture", "rank": 10, "score": 101760 }, { "content": "Title: Hungry gap Content: In cultivation of vegetables in a British-type climate , the hungry gap is the gardeners ' name for the period in spring when there is little or no fresh produce available from a vegetable garden or allotment .

There are four basic approaches , that can also be combined : Two or more crops in succession : After one crop is harvested , another is planted in the same space . The length of the growing season , climate , and crop selection are key factors . For example , a cool season spring crop could be followed by a heat-loving summer crop . Same crop , successive plantings : Several smaller plantings are made at timed intervals , rather than all at once . The plants mature at staggered dates , establishing a continuous harvest over an extended period . Lettuce and other salad greens are common crops for this approach . Within a small garden or home garden , this method is useful in circumventing the initial large yield from the crop and rather providing a steady , smaller yield that may be consumed in its entirety . This is also known as relay planting . Two or more crops simultaneously : Non-competing crops , often with different maturity dates , are planted together in various patterns . Intercropping is one pattern approach ; companion planting is a related , complementary practice . This method is also known as Interplanting : The practice of growing two types of plants in the same space . Interplanting requires a certain amount of preplanning and knowledge of the maturity dates of different types of vegetables . It has been noted that successful interplanting and intensive gardening is done in raised beds within the planting areas . Planting two or more non-competing crops may raise issues with soil-borne diseases and insects that only affect one type of plant . Depending on how close the interplanting varieties are , crop failure is a possibility . Same crop , different maturity dates : Several varieties are selected , with different maturity dates : early , main season , late . Planted at the same time , the varieties mature one after the other over the season . These techniques can be used to design complex , highly productive cropping systems . The more involved the plan , the more detailed knowledge is required of the specific varieties and how they perform in a particular growing location . A number of tertiary institutions have written about the advantages of succession planting and outlined extensive guides to this bio intensive style of small scale crop farming . There are a numerous differences in guides to succession planting due to the diverse climate and soil conditions experienced around the world . There are significant differences between cold weather succession planting and warm weather succession planting . The term `` succession planting '' usually appears in literature for home gardening and small-scale farming , although the techniques apply to any scale . Some definitions include one or more , but not all of the four techniques described above . Succession planting is often used in organic farming .

They frequently stress water availability by depleting soil moisture , reducing stream flows , lowering lake and reservoir levels , and diminishing groundwater supplies . This ultimately affects several economic activities including for example , decreased agricultural production , less hydro-electric power generation , and increased freshwater transportation costs . Droughts also create major environmental hazards such as reduced water quality , wetland loss , soil erosion and degradation , and ecological habitat destruction . Although most regions of Canada have experienced drought , many of the southern regions of the Canadian Prairies and interior British Columbia are most susceptible . During the past two centuries , at least 40 droughts have occurred in western Canada with multi-year episodes being observed in the 1890s , 1910s , 1930s , 1960s , 1980s , and the early 2000s . Droughts in southern Ontario/Quebec are usually shorter , smaller in area , less frequent , and less intense . Nonetheless , there have been some major drought occurrences there as well during the 20th century . Droughts in the Atlantic Provinces occur even less frequently . Droughts are less of a concern for northern Canada mainly due to their lower population densities . However , increased frequencies of forest fires during drought years can have serious economic impacts . Rarely has drought been as serious or extensive as the recent 1999-2004 episode . This was the worst drought for at least a hundred years in parts of the Canadian Prairies .

For example , the number of natural Prairie ponds in May 2002 was the lowest on record while in 2001 , Great Lakes-St . Lawrence water levels plunged to their lowest point in more than 30 years , thereby significantly increasing marine transportation costs . In British Columbia and Manitoba , hydro-electric generation was curtailed , necessitating additional purchases of power from neighboring jurisdictions . In 2002 , the incidence of forest fires in Alberta increased to five times the ten-year average while in summer 2003 , populated regions of interior British Columbia were stricken by drought-enhanced fires . Long-lasting impacts include soil degradation by wind erosion and deterioration of grasslands that could take decades and longer to recover . High surface temperatures intensify droughts by enhancing evapotranspiration in summer , and increasing sublimation and melting of the snowpack during winter . During the 20th century , mean annual air temperature has increased by around 1 ° C over southern Canada with the greatest warming in the west and the largest rates during winter and spring . Over the same period , annual precipitation has significantly increased over most of southern Canada with the exception of southern Alberta and Saskatchewan . Coincident with the large increases in spring temperature , the 1980s to the present have been associated with rapid reductions in snow cover during the second half of the snow season . Over the last 30 to 50 years , average stream flow has decreased in many parts of Canada with significant reductions in the south . Great Lakes ' water levels have shown substantial variability during the 20th century with no evidence of a long-term trend . Lower levels coincided with the droughts of the 1930s , early 1960s , and the recent 1999-2001 dry period . Over the Prairies , the numbers and water levels of wetlands have shown no clear trend over the last 40 to 50 years . Indices used to measure drought show considerable decadal-scale variability with no long-term trends discernible in any portion of the country . Most southern regions of Canada , however , experienced drought conditions during the late 1990s to early 2000s . The worst and most prolonged Canadian Prairie-wide droughts during the instrumental period occurred in the early part of the 20th century ( 1920s and 1930s ) .

This reduces rain runoff by allowing stormwater to soak into the ground ( as opposed to flowing into storm drains and surface waters which causes erosion , water pollution , flooding , and diminished groundwater ) . They should be designed for specific soils and climates . The purpose of a rain garden is to improve water quality in nearby bodies of water and to ensure that rainwater becomes available for plants as groundwater rather than being sent through stormwater drains straight out to sea . Rain gardens can cut down on the amount of pollution reaching creeks and streams by up to 30 % . Native and adapted plants are recommended for rain gardens because they are more tolerant of the local climate , soil , and water conditions ; have deep and variable root systems for enhanced water infiltration and drought tolerance ; habitat value and diversity for local ecological communities ; and overall sustainability once established . There can be trade-offs associated with using native plants , including lack of availability for some species , late spring emergence , short blooming season , and relatively slow establishment . The plants -- a selection of wetland edge vegetation , such as wildflowers , sedges , rushes , ferns , shrubs and small trees -- take up excess water flowing into the rain garden . Water filters through soil layers before entering the groundwater system . Root systems enhance infiltration , maintain or even augment soil permeability , provide moisture redistribution , and sustain diverse microbial populations involved in biofiltration . Also , through the process of transpiration , rain garden plants return water vapor to the atmosphere . A more wide-ranging definition covers all the possible elements that can be used to capture , channel , divert , and make the most of the natural rain and snow that falls on a property .

It is a perennial herb with a woody stem that can grow as tall as 30 cm . The leaves on the single terminal rosette are erect or horizontal ( with age ) and held at the end of linear petioles , which are typically 20 -- 35 mm ( approximately 1 inch ) long at flowering time . The carnivorous leaves are sub-orbicular and small at 2.5-3 mm ( approximately 1/10 inch ) wide and 2 -- 3 mm ( approximately 1/10 inch ) long . Inflorescences are 20 - long with pink or white flowers being produced on 50 - to 70-flowered crowded racemes from July to September during the dry season . Drosera paradoxa is found in skeletal sandy soils over sandstone in or along the banks of seasonally dry creeks or in sandstone cracks . During the wet season from March to April , its habitat is typically flooded with fast-flowing water . Drosera paradoxa is native to the west and north coasts of the Kimberley region inland to Beverley Springs , Western Australia and east to Arnhem Land and Kakadu National Park in the Northern Territory . It was first described by Australian botanist Allen Lowrie in a 1997 issue of Nuytsia , the journal of the Western Australian Herbarium . Early field observations of this species were initially confusing , which is the source of this species ' specific epithet , paradoxa . Some populations seemed to be annual with new seedlings replacing the mature , woody plants that had existed there the previous year . Other populations had no woody stems , while others were tall and mature . Several trips into the field from 1993 to 1997 were required to reveal these different forms to be only stages in this species ' perennial growth cycle from seedling to pincushion basal rosette to erect woody-stemmed specimen . The type specimen was collected on 1 August 1996 near Wren Creek on the road to Pantijan on a tributary of Bachsten Creek in Western Australia . Lowrie assessed this species ' conservation status as common and not under threat in 1997 . It is closely related to D. petiolaris , but differs from that species most notably by its tall woody stem whereas D. petiolaris forms clumps of many basal rosettes from a common perennial rootstock .", "qid": "622", "docid": "Drosera_paradoxa", "rank": 19, "score": 95524 }, { "content": "Title: Moisture stress Content: Moisture stress occurs when the water in a plant 's cells is reduced to less than normal levels . This can occur because of a lack of water in the plant 's root zone , higher rates of transpiration than the rate of moisture uptake by the roots , for example , because of an inability to absorb water due to a high salt content in the soil water or loss of roots due to transplantation . Moisture stress is more strongly related to water potential than it is to water content . Moisture stress also has an effect on stomatal openings of a plant , mainly causing a closure in stomata as to reduce the amount of carbon dioxide assimilation . Closing of the stomata also slows the rate of transpiration , which limits water loss and helps to prevent the wilting effects of moisture stress . This closing can be trigged by the roots sensing dry soil and in response producing the hormone ABA which when transported up the xylem into the leaves will reduce stomatal conductance and wall extensibility of growing cells . This lowers the rates of transpiration , photosynthesis and leaf expansion . ABA also increases the loosening of growing root cell walls and in turn increases root growth in an effort to find water in the soil . Phenotypic response of plants to long-term water stress was measured in corn and showed that plants respond to water stress with both an increase in root growth both laterally and vertically . In all Droughted conditions the corn showed decrease in plant height and yield due to the decrease in water availability . Genes induced during water-stress conditions are thought to function not only in protecting cells from water deficit by the production of important metabolic proteins but also in the regulation of genes for signal transduction in the water-stress response . There are four pathways that have been described that show the plants genetic response to moisture stress ; two are ABA dependent while two are ABA independent . They all affect gene expression that increases the plants water stress tolerance . The effects of moisture stress on photosynthesis can depend as much on the velocity and degree of photosynthetic recovery , as it depends on the degree and velocity of photosynthesis decline during water depletion . Plants that are subjected to mild stress can recover in 1 -- 2 days however , plants subjected to severe water stress will only recover 40-60 % of its maximum photosynthetic rates the day after re watering and may never reach maximum photosynthetic rates . The recovery from moisture stress starts with an increase in water content in leaves reopening the stomata then the synthesis of photosynthetic proteins .", "qid": "622", "docid": "Moisture_stress", "rank": 20, "score": 94409 }, { "content": "Title: Effects of global warming Content: The effects of global warming are the environmental and social changes caused ( directly or indirectly ) by human emissions of greenhouse gases .

Future effects of climate change will vary depending on climate change policies and social development . The two main policies to address climate change are reducing human greenhouse gas emissions ( climate change mitigation ) and adapting to the impacts of climate change . Geoengineering is another policy option . Near-term climate change policies could significantly affect long-term climate change impacts . Stringent mitigation policies might be able to limit global warming ( in 2100 ) to around 2 ° C or below , relative to pre-industrial levels .

Once air becomes saturated , water will condense out to form clouds , dew or films of water over leaves . It is this last instance that makes VPD important for greenhouse regulation . If a film of water forms on a plant leaf , it becomes far more susceptible to rot . On the other hand , as the VPD increases , the plant needs to draw more water from its roots . In the case of cuttings , the plant may dry out and die . For this reason the ideal range for VPD in a greenhouse is from 0.45 kPa to 1.25 kPa , ideally sitting at around 0.85 kPa . As a general rule , most plants grow well at VPDs of between 0.8 and 0.95 kPa . A series of membership functions for defining optimality degree of VPD at different light condition and growth stages of greenhouse tomato can be found in the work of Shamshiri .

Rice is the main crop grown during the rainy season , and under usual conditions , rainfall is adequate for rice production . However , if rain ceases to fall for several weeks to a month at a critical time in the rice growing cycle , yields will be significantly affected . Upland rice varieties , although adapted to a lower moisture requirement , are also affected by intermittent rains because farmers have no means of storing water in their fields . Rice accounted for over 80 percent of agricultural land and between 73 percent and 84 percent of total agricultural output of major crops throughout the 1980s , except in 1988 and into the early 1990s . Rice paddies also yield fish in irrigation ditches in na ( lowland rice fields ) . Production of rice more than doubled between 1974 and 1986 , from fewer than 700,000 tons to 1.4 million tons ; however , drought in 1987 and 1988 cut annual yields by nearly one-third , to about 1 million tons , forcing the government to rely on food aid for its domestic requirements . In 1988 and 1989 , some 140,000 tons of rice were donated or sold to Laos . With improved weather and the gradual decollectivization of agriculture , an important measure under the New Economic Mechanism -- rice production surged by 40 percent in 1989 . The increase in production reflected the importance of the agricultural sector to the economy and was largely responsible for the economic recovery following the droughts . In 1990 production continued to increase , although at a much slower rate , and the point of self-sufficiency in rice was reached : a record 1.5 million tons . Sufficiency at a national level , however , masks considerable regional differences . The southern Mekong provinces of Khammouan , Savannakhét , and Champasak regularly produce surpluses , as do Vientiane and Oudômxai provinces , but an inadequate transportation system often makes it easier for provinces with shortages to purchase rice from Thailand or Vietnam than to purchase it from other provinces . According to some sources , the percentage of the labor force engaged in rice production declined gradually , by over 30 percent between 1986 and 1991 , a trend encouraged by the government because it tended to increase export-oriented production . However , some feared this trend would threaten sustained self-sufficiency in food , another key goal of the government . Sustained selfsufficiency however , more likely depends on a continued increase in the use of agricultural inputs such as fertilizers and improved strains of rice , and on the implementation of extension and research services rather than on the actual number of workers involved in planting . The overall increase in rice production throughout the 1980s was the result of higher productivity per hectare , rather than of an increase in the land area planted in rice ; in fact , the area planted in rice decreased during the 1980s , from 732,000 hectares in 1980 to 657,000 hectares in 1990 .

Due to clearing of land and building of towns and cities , land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers , and then to coastal estuaries and bays . Extra nutrients are also supplied by treatment plants , golf courses , fertilizers , and farms . These nutrients result in an excessive growth of plant life known as an algal bloom . This can change a lake 's natural food web , and also reduce the amount of dissolved oxygen in the water for organisms to breathe . Both these things cause animal and plant death rates to increase as the plants take in poisonous water while the animals drink the poisoned water . This contaminates water , making it undrinkable , and sediment quickly fills the lake . Cultural eutrophication is a form of water pollution . Cultural eutrophication also occurs when excessive fertilizers run into lakes and rivers . This encourages the growth of algae ( algal bloom ) and other aquatic plants . Following this , overcrowding occurs and plants compete for sunlight , space and oxygen . Overgrowth of water plants also blocks sunlight and oxygen for aquatic life in the water , which in turn threatens their survival . Algae also grows easily , thus threatening other water plants no matter whether they are floating , half-submerged , or fully submerged . Not only does this cause algal blooming , it can cause an array of more long-term effects on the water such as damage to coral reefs and deep sea animal life . It also speeds up the damage of both marine and also affects humans if the effects of algal blooming is too drastic . Fish will die and there will be lack of food in the area .

Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth . It provides suitable conditions for many types of ecosystems , as well as water for hydroelectric power plants and crop irrigation . The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts . If enough moisture and upward motion is present , precipitation falls from convective clouds ( those with strong upward vertical motion ) such as cumulonimbus ( thunder clouds ) which can organize into narrow rainbands . In mountainous areas , heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains . On the leeward side of mountains , desert climates can exist due to the dry air caused by downslope flow which causes heating and drying of the air mass . The movement of the monsoon trough , or intertropical convergence zone , brings rainy seasons to savannah climes . The urban heat island effect leads to increased rainfall , both in amounts and intensity , downwind of cities . Global warming is also causing changes in the precipitation pattern globally , including wetter conditions across eastern North America and drier conditions in the tropics . Antarctica is the driest continent . The globally averaged annual precipitation over land is 715 mm , but over the whole Earth it is much higher at 990 mm . Climate classification systems such as the Köppen classification system use average annual rainfall to help differentiate between differing climate regimes . Rainfall is measured using rain gauges .

Droughts are likely to particularly affect the 66 percent of Americans whose communities depend on surface water . As for drinking water quality , there are concerns about disinfection by-products , lead , perchlorates and pharmaceutical substances , but generally drinking water quality in the U.S. is good .

The reuse of treated wastewater for non-potable uses is also becoming increasingly common . Pollution through wastewater discharges , a major issue in the 1960s , has been brought largely under control . Most Americans are served by publicly owned water and sewer utilities . Eleven percent of Americans receive water from private ( so-called `` investor-owned '' ) utilities . In rural areas , cooperatives often provide drinking water .

Studied by glaciologists , the temporal coincidence of glacier retreat with the measured increase of atmospheric greenhouse gases is often cited as an evidentiary underpinning of global warming . Mid-latitude mountain ranges such as the Himalayas , Alps , Rocky Mountains , Cascade Range , and the southern Andes , as well as isolated tropical summits such as Mount Kilimanjaro in Africa , are showing some of the largest proportionate glacial losses . Glacier mass balance is the key determinant of the health of a glacier . If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance ; if the accumulation is less than the ablation , the glacier will retreat . Glaciers in retreat will have negative mass balances , and if they do not find an equilibrium between accumulation and ablation , will eventually disappear . The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the present . Subsequently , until about 1940 , glaciers around the world retreated as the climate warmed substantially . Glacial retreat slowed and even reversed temporarily , in many cases , between 1950 and 1980 as global temperatures cooled slightly . Since 1980 , a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous , so much so that some glaciers have disappeared altogether , and the existences of many of the remaining glaciers are threatened . In locations such as the Andes of South America and Himalayas in Asia , the demise of glaciers in these regions has the potential to affect water supplies in those areas . The retreat of mountain glaciers , notably in western North America , Asia , the Alps and tropical and subtropical regions of South America , Africa and Indonesia , provide evidence for the rise in global temperatures since the late 19th century .

A carbon diet is an effective way to understand the amount of impact on the environment and how to make meaningful changes . A low carbon diet is a way of reducing impact by choosing food that causes much less pollution . Trees : Protecting forests and planting new trees contributes to the absorption of carbon dioxide from the air . There are many opportunities to plant trees in the yard , along roads , in parks , and in public gardens . In addition , some charities plant fast-growing trees -- for as little as $ US0 .10 per tree -- to help people in tropical developing countries restore the productivity of their lands . Conversely , clearing old-growth forests adds to the carbon in the atmosphere , so buying non-old-growth paper is good for the climate as well as the forest . Labels : The Energy Star label can be seen on many household appliances , home electronics , office equipment , heating and cooling equipment , windows , residential light fixtures , and other products . Energy Star products use less energy . Travel : In the United States , perception towards climate change influenced people to change their travel lifestyle . More than a third of Americans have changed their travel habits in 2008 , versus only 14 % in 2007 . Cars : Purchasing a vehicle which gets high gas mileage helps to reduce emissions of carbon dioxide . Flying : Avoiding air travel and particularly frequent flyer programs has a high benefit because the convenience makes frequent , long distance travel easy , and high-altitude emissions are more potent for the climate than the same emissions made at ground level . Walking and running are among the least environmentally harmful modes of transportation , followed by the bicycle . Many energy suppliers in various countries worldwide have options to purchase part or pure `` green energy . '' The wind energy produced in Denmark , for example , provides about 20 percent of the country 's total electricity needs . These methods of energy production emit no greenhouse gases once they are up and running . Carbon offsets : The principle of carbon offset is thus : one decides that they do n't want to be responsible for accelerating climate change , and they 've already made efforts to reduce their carbon dioxide emissions , so they decide to pay someone else to further reduce their net emissions by planting trees or by taking up low-carbon technologies . Every unit of carbon that is absorbed by trees -- or not emitted due to your funding of renewable energy deployment -- offsets the emissions from their fossil fuel use . In many cases , funding of renewable energy , energy efficiency , or tree planting -- particularly in developing nations -- can be a relatively cheap way of making an individual `` carbon neutral '' .

Overfishing can occur in water bodies of any sizes , such as ponds , rivers , lakes or oceans , and can result in resource depletion , reduced biological growth rates and low biomass levels . Sustained overfishing can lead to critical depensation , where the fish population is no longer able to sustain itself . Some forms of overfishing , for example the overfishing of sharks , has led to the upset of entire marine ecosystems . The ability of a fishery to recover from overfishing depends on whether the ecosystem 's conditions are suitable for the recovery . Dramatic changes in species composition can result in an ecosystem shift , where other equilibrium energy flows involve species compositions different from those that had been present before the depletion of the original fish stock . For example , once trout have been overfished , carp might take over in a way that makes it impossible for the trout to re-establish a breeding population . Overfishing occurs when more fish are caught than the population can replace through natural reproduction . Gathering as many fish as possible may seem like a profitable practice , but overfishing has serious consequences .

Classification into spring or winter wheat is common and traditionally refers to the season during which the crop is grown . For winter wheat , the physiological stage of heading is delayed until the plant experiences vernalization , a period of 30 to 60 days of cold winter temperatures ( 0 ° to 5 ° C ; 32 -- 41 ° F ) . Winter wheat is usually planted from September to November in the Northern Hemisphere and harvested in the summer or early autumn of the next year . In some places ( e.g. Chile ) , winter wheat even celebrates a `` birthday '' , meaning it is harvested more than a year after it was planted . Winter wheat usually provides higher yields compared to spring wheat . So-called `` facultative '' wheat varieties need shorter periods of vernalization time ( 15 -- 30 days ) and temperatures of 3 ° to 15 ° C ( 37 -- 59 ° F ) . In many areas facultative varieties can be grown either as winter or as a spring , depending on time of sowing . In countries that experience mild winters , such as in South Asia ( India , Pakistan , Nepal , Bangladesh ) , North Africa , the Middle East and the lower latitudes ( e.g. Sonora in Mexico ) , spring wheat ( not requiring a period of vernalization ) is also sown in the autumn ( November/December ) and harvested in late spring ( April - May ) the next year . This spring wheat planted in the autumn and grown over the winter is sometimes also incorrectly called `` winter wheat '' . Hard winter wheats have a higher gluten protein content than other wheats . They are used to make flour for yeast breads , or are blended with soft spring wheats to make the all-purpose flour used in a wide variety of baked products .

Corn , soybeans , and wheat are three common crops often grown using monocropping techniques . While economically a very efficient system , allowing for specialization in equipment and crop production , monocropping is also controversial , as it can damage the soil ecology ( including depletion or reduction in diversity of soil nutrients ) and provide an unbuffered niche for parasitic species , increasing crop vulnerability to opportunistic insects , plants , and microorganisms . The result is a more fragile ecosystem with an increased dependency on pesticides and artificial fertilizers . The concentrated presence of a single cultivar , genetically adapted with a single resistance strategy , presents a situation in which an entire crop can be wiped out very quickly by a single opportunistic species . An example of this would be the potato famine of Ireland in 1845 -- 1849 , and according to Devlin Kuyek is the main cause of the current food crisis with monoculture rice crops failing as the effects of climate change become more acute . Monocropping as an agricultural strategy tends to emphasize the use of expensive specialized farm equipment -- an important component in realizing its efficiency goals . This can lead to an increased dependency on fossil fuels and reliance on expensive machinery that can not be produced locally and may need to be financed . This can make a significant change in the economics of farming in regions that are accustomed to self-sufficiency in agricultural production . In addition , political complications may ensue when these dependencies extend across national boundaries . The controversies surrounding monocropping are complex , but traditionally the core issues concern the balance between its advantages in increasing short-term food production -- especially in hunger-prone regions -- and its disadvantages with respect to long-term land stewardship and the fostering of local economic independence and ecological sustainability . Advocates of monocropping tend to claim that in its absence many human populations would be reduced to starvation or to a degraded level of civilization comparable to the Dark Ages . On the other hand , critics of monocropping dispute these claims and attribute them to corporate special interest groups , citing the damage that monocropping causes to societies and the environment . A difficulty with monocropping is that the solution to one problem -- whether economic , environmental or political -- may result in a cascade of other problems . For example , a well-known concern is pesticides and fertilizers seeping into surrounding soil and groundwater from extensive monocropped acreage in the U.S. and abroad . This issue , especially with respect to the pesticide DDT , played an important role in focusing public attention on ecology and pollution issues during the 1960s when Rachel Carson published her landmark book Silent Spring . Soil depletion is also a negative effect of mono-cropping . Crop rotation plays an important role in replenishing soil nutrients , especially atmospheric nitrogen converted to usable forms by nitrogen-fixing plants used in fallow fields . In addition , it performs an important role in preventing pathogen and pest build-up . In a monocropping regime , farmers are less likely to rotate their crops and replenish such essential soil nutrients . In addition , artificial high-nitrogen fertilizers can `` burn '' the soil by creating an unfavorable environment for indigenous organisms , a phenomenon well-known to organic gardeners and farmers ( who avoid it ) , resulting in further disruption of soil ecology and dependence on further short-term fertilizer strategies . Lacking a stable ecology , in the absence of substantial irrigation and chemical `` fixes '' the soil can become dry and begin to erode . As the soil becomes arid and useless , the need for more land becomes an issue , leading to the destruction of even more land -- a high-tech version of slash and burn agriculture . Under certain circumstances monocropping can lead to deforestation or the displacement of indigenous peoples . In order to help reduce dependence on fossil fuels the U.S. government subsidizes the monocropping of corn and soybeans to be used in ethanol production . However , monocropping itself is highly chemical - and energy-intensive , as studies by Nelson ( 2006 ) indicate . Such studies have shown that the `` hidden '' energy costs associated with producing each unit of bio-fuel are significantly larger than the amount of energy available from the fuel itself .", "qid": "622", "docid": "Monocropping", "rank": 78, "score": 80414 }, { "content": "Title: Effect of radiation on perceived temperature Content: The `` radiation effect '' results from radiation heat exchange between human bodies and surrounding surfaces , such as walls and ceilings . It may lead to phenomena such as houses feeling cooler in the winter and warmer in the summer at the same temperature . For example , in a room in which air temperature is maintained at 22 ° Celsius at all times , but in which the inner surfaces of the house is estimated to be an average temperature of 10 ° Celsius in the winter or 25 ° Celsius in the summer , heat transfer from the surfaces to the individual will occur , resulting in a difference in the perceived temperature . We can observe and compare the rate of radiation heat transfer between a person and the surrounding surfaces if we first make a few simplifying assumptions : The heat exchange in the environment is in a `` steady state '' , meaning that there is a constant flow of heat either into or out of the house . The person is completely surrounded by the interior surfaces of the room . Heat transfer by convection is not considered . The walls , ceiling , and floor are all at the same temperature . For an average person , the outer surface area is 1.4 m ² , the surface temperature is 30 ° Celsius , and the emissivity is 0.95 . Emissivity is the ability of a surface to emit radiant energy compared to that of a black body at the same temperature .

A hill or mountain top will be radiatively warmed by the Sun which in turn heats the air just above it . Air at a similar altitude over an adjacent valley or plain does not get warmed so much because of the greater distance to the ground below it . The effect may be enhanced if the lower lying ground is shaded by the mountain and so receives less heat . The air over the hill top is now warmer than the air at a similar altitude around it and will rise through convection . This creates a lower pressure region into which the air at the bottom of the slope flows , causing the wind . It is common for the air rising from the tops of large mountains to reach a height where it cools adiabatically to below its dew point and forms cumulus clouds .

A turion may be an underground bud . Some aquatic plant species produce overwintering turions , especially in the genera Potamogeton , Myriophyllum , Aldrovanda and Utricularia . These plants produce turions in response to unfavourable conditions such as decreasing day-length or reducing temperature . They are derived from modified shoot apices and are often rich in starch and sugars enabling them to act as storage organs . Although they are hardy ( frost resistant ) , it is probable that their principal adaptation is their ability to sink to the bottom of a pond or lake when the water freezes . Because water expands anomalously at lower temperatures , water at 4 ° C is denser than colder water and stays at the bottom , and in this water turions over-winter before rising again in the spring .

His measurements of bottom depths , tidal currents , and tidal elevations on the vast shelf areas off the East Siberian Sea correctly described the propagation of tides as Poincare waves . Upon his return from this long expedition exploring the shelf seas to the north of Siberia , he became the chair in meteorology at the University of Bergen in Norway . He was made director of California 's Scripps Institution of Oceanography in 1936 , initially for 3 years but the intervention of World War II meant he held the post until 1948 . During 33 expeditions with the research vessel E. W. Scripps in the years 1938-1941 he produced a detailed oceanographic dataset off the coast of California . He also developed a simple theory of the general ocean circulation postulating a dynamical vorticity balance between the wind-stress curl and the meridional gradient of the Coriolis parameter , the Sverdrup balance . This balance describes wind-driven ocean gyres away from continental margins at western boundaries . After leaving SIO , he returned home to become director of the Norwegian Polar Institute and continued to contribute to oceanography , ocean biology and polar research . In biological oceanography , his Critical Depth Hypothesis published in 1953 was a significant milestone in the explanation of phytoplankton spring blooms . His many publications include the magnum opus The Oceans : Their Physics , Chemistry and General Biology by Harald Sverdrup , Martin W. Johnson and Richard H.

Sea level rise is usually attributed to global climate change by thermal expansion of the water in the oceans and by melting of Ice sheets and glaciers on land . Melting of floating ice shelves or icebergs at sea raises sea levels only slightly . Sea level rise at specific locations may be more or less than the global average . Local factors might include tectonic effects , subsidence of the land , tides , currents , storms , etc. . Sea level rise is expected to continue for centuries . Because of the slow inertia , long response time for parts of the climate system , it has been estimated that we are already committed to a sea-level rise of approximately 2.3 m for each degree Celsius of temperature rise within the next 2,000 years .

The prominent oceanographer of the equatorial Pacific , Townsend Cromwell , was killed in an airplane crash on 2 June 1958 . The accident , also fatal to the American fisheries research biologist Bell M. Shimada , occurred near Guadalajara as the men were en route to join the Scot Expedition at Acapulco . Cromwell was Senior Scientist with the Inter-American Tropical Tuna Commission and Research Associate at Scripps Institution of Oceanography , La Jolla , California . His field of work was the physical environment and its relation to fisheries . He became a weather officer in the Army Air Force during World War II . . After receiving a B.A. degree from University of California ( Los Angeles ) in 1947 , he returned to La Jolla , his boyhood home , as a student at Scripps , receiving an M.S. degree in oceanography from the University of California ( La Jolla ) in 1949 . At Scripps he was strongly influenced by H. U. Sverdrup . From 1949 to 1953 he was Oceanographer at Pacific Oceanic Fishery Investigations , Honolulu , Oscar Elton Sette , then Director , and Cromwell initiated a far-sighted and intensive survey of the physical and biological characteristics of Pacific equatorial waters , which had been the subject of much speculation but little observation . For many months he participated in the field work from the HUGH M. SMITH , and for more and harder months he carried out the analysis of the observations . As a result of this pioneering work , the knowledge of the physical and biological structure of the equatorial Pacific Ocean has been vastly advanced . These achievements are the more remarkable when one notes that comparable surveys of the equatorial Atlantic and Indian oceans are still lacking . Cromwell confirmed the existence of upwelling at the equator , disproved the existence of upwelling at the northern edge of the Equatorial Countercurrent , and originated a reasonable model of wind-induced current transport in the equatorial zone During these studies he recognized the significance of the unexpected drift of long-line fishing gear at the equator , and in 1952 he led a HUGH M. SMITH cruise using drogues in current measurements . Thus , he was responsible for the discovery of the Equatorial Undercurrent the fourth member of the equatorial current system ( the North Equatorial Current , Equatorial Countercurrent , and South Equatorial Current having been known for a century ) . The existence of the Equatorial Undercurrent has been amply confirmed , during measurements completed a few days before Cromwell 's death , by his colleagues J. A. Knauss and J. E. King .

Flandrin had won France 's Prix de Rome in 1832 , a bursary which provided the winner with a trip to Rome to concentrate on their vocation . There , Flandrin produced this study , which he sent back to Paris in 1837 , in fulfillment of the bursary 's requirements for the student to submit works in the tradition of various genres . In 1857 , Napoleon III purchased the painting , which is now in the collection of Paris 's Louvre . The painting gained attention among contemporary French art critics , and remains one of Flandrin 's best-known works , despite being produced relatively early in his career . The subject is an unidentified youth , an `` ephebe '' , who sits nude on a rock with his arms wrapped around his legs and his head resting on his knees , eyes closed . There is a sea in the background , and no distinguishable landmarks locate the figure . The enigmatic scene provides no explanation for the figure 's pose : Théophile Gautier ( 1811 -- 1872 ) commented that the young man could be shipwrecked on a deserted island , or be a shepherd who has lost his flock . Ultimately , any explanation for this scene is left to the imagination , leading to comparisons with Surrealist art in the twentieth century . In examining the influence of German aesthetic theory on French art , critic Elizabeth Prettejohn finds that the roundedness of form and `` flawless '' modeling of flesh would have met with Johann Joachim Winckelmann 's approval as an examplar of the beautiful . Prettejohn compares the figure 's almost circular pose and sparse framing with that of Leonardo da Vinci 's Vitruvian Man .

As awareness of the work grew , the painting became an icon of homosexual culture in the 20th century .

Maury made many important new contributions to charting winds and ocean currents , including ocean lanes for passing ships at sea . In 1825 at age 19 , Maury obtained , through the then-US Congressman Sam Houston , a midshipman 's warrant in the United States Navy . As a midshipman on board the frigate , he almost immediately began to study the seas and record methods of navigation . When a leg injury left him unfit for sea duty , Maury devoted his time to the study of navigation , meteorology , winds , and currents . He became Superintendent of the U.S. Naval Observatory and head of the Depot of Charts and Instruments . Here , Maury studied thousands of ships ' logs and charts .

On Antarctica the deficiency increased by 75 % . Mountain glaciers are retreating and the cumulative mean thickness change has accelerated from about − 1.8 to − 4 m in 1965 to 1970 to about − 12 to − 14 m in the first decade of the 21st century .

Melting of floating ice shelves or icebergs at sea raises sea levels only slightly . Sea level rise at specific locations may be more or less than the global average . Local factors might include tectonic effects , subsidence of the land , tides , currents , storms , etc. . Sea level rise is expected to continue for centuries .

Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' . There are significant regional differences , with Americans and Chinese ( whose economies are responsible for the greatest annual CO2 emissions ) among the least concerned .", "qid": "625", "docid": "Global_warming", "rank": 14, "score": 120990 }, { "content": "Title: Sea surface temperature Content: Sea surface temperature ( SST ) is the water temperature close to the ocean 's surface . The exact meaning of surface varies according to the measurement method used , but it is between 1 mm and 20 m below the sea surface . Air masses in the Earth 's atmosphere are highly modified by sea surface temperatures within a short distance of the shore . Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass . Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth 's oceans . Tropical cyclones can also cause a cool wake , due to turbulent mixing of the upper 30 m of the ocean . SST changes diurnally , like the air above it , but to a lesser degree . There is less SST variation on breezy days than on calm days . In addition , ocean currents such as the Atlantic Multidecadal Oscillation ( AMO ) , can effect SST 's on multi-decadal time scales , a major impact results from the global thermohaline circulation , which affects average SST significantly throughout most of the world 's oceans . Coastal SSTs can cause offshore winds to generate upwelling , which can significantly cool or warm nearby landmasses , but shallower waters over a continental shelf are often warmer . Onshore winds can cause a considerable warm-up even in areas where upwelling is fairly constant , such as the northwest coast of South America .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples .

Studied by glaciologists , the temporal coincidence of glacier retreat with the measured increase of atmospheric greenhouse gases is often cited as an evidentiary underpinning of global warming . Mid-latitude mountain ranges such as the Himalayas , Alps , Rocky Mountains , Cascade Range , and the southern Andes , as well as isolated tropical summits such as Mount Kilimanjaro in Africa , are showing some of the largest proportionate glacial losses . Glacier mass balance is the key determinant of the health of a glacier . If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance ; if the accumulation is less than the ablation , the glacier will retreat . Glaciers in retreat will have negative mass balances , and if they do not find an equilibrium between accumulation and ablation , will eventually disappear . The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the present . Subsequently , until about 1940 , glaciers around the world retreated as the climate warmed substantially . Glacial retreat slowed and even reversed temporarily , in many cases , between 1950 and 1980 as global temperatures cooled slightly . Since 1980 , a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous , so much so that some glaciers have disappeared altogether , and the existences of many of the remaining glaciers are threatened .

Following John T. Hollin 's work ( 1962 ) suggesting that climatic warming and rising sea-level cause Antarctic ice shelves to retreat , Mercer postulated that the West Antarctic ice sheet , being grounded well below sea-level and terminating in floating ice shelves , was vulnerable to these changes and may have collapsed altogether during the last interglacial when Antarctica may have been warmer and sea-level may have been higher . In 1978 , in the science magazine Nature , Mercer pointed out that `` green-house '' warming from burning fossil fuel could have the same effect during the present interglacial . Two studies published 12 May 2014 confirm Mercer 's assumption . Climate scientist James Hansen has coined the term , `` John Mercer effect .

There was increased public interest in 2013 in the run-up to publication of the IPCC Fifth Assessment Report , and despite concerns that a 15-year period was too short to determine a meaningful trend , the IPCC included a section on a hiatus , which it defined as a much smaller increasing linear trend over the 15 years from 1998 to 2012 , than over the 60 years from 1951 to 2012 . Various studies examined possible causes of the short-term slowdown . Even though the overall climate system has continued to accumulate energy due to Earth 's positive energy budget , the available temperature readings at the Earth 's surface indicate slower rates of increase in surface warming than in the prior decade . Since measurements at the top of the atmosphere show that Earth is receiving more energy than it is radiating back into space , the retained energy should be producing warming in the Earth 's climate system . Research reported in July 2015 on an updated NOAA dataset casts doubt on the existence of a hiatus , and it finds no indication of a slowdown even in earlier years . Scientists working on other datasets welcomed this study , though they have expressed the view that the recent warming trend was less than in previous periods of the same length . Subsequently , a detailed study supports the conclusion that warming is continuing , but it also find there was less warming between 2001 and 2010 than climate models had predicted , and that this slowdown might be attributed to short-term variations in the Pacific decadal oscillation ( PDO ) , which was negative during that period . Another review finds `` no substantive evidence '' of a pause in global warming . A statistical study of global temperature data since 1970 concludes that the term ` hiatus ' or ` pause ' is not justified . Independent of these discussions about data and measurements for earlier years , 2015 turned out to be much warmer than any of the earlier years , already before El Niño conditions started . The warmth of 2015 largely ended any remaining scientific credibility of claims that the supposed `` hiatus '' since 1998 had any significance for the long-term warming trend . In January 2017 , a study published in the journal Science Advances cast further doubt on the existence of a recent pause , with more evidence that ocean temperatures have been underestimated . An April 2017 study found the data consistent with a steady warming trend globally since the 1970s , with fluctuations within the expected range of short term variability .", "qid": "625", "docid": "Global_warming_hiatus", "rank": 64, "score": 92383 }, { "content": "Title: Konrad Steffen Content: Konrad `` Koni '' Steffen ( born 1952 ) is a glaciologist and the former director of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder , a position he held from 2005 until he took office as the director of the Swiss Federal Institute for Forest , Snow and Landscape Research on July 1 , 2012 .

The Last Glacial Maximum and sea-level minimum occurred c. 21,000 years before present ( BP ) . Antarctic ice cores show gradual warming beginning 3000 years later . At about 14,700 BP , there was a large pulse of meltwater , identified as Meltwater pulse 1A , probably from either the Antarctic ice sheet or the Laurentide ice sheet . Meltwater pulse 1A produced a marine transgression that raised global sea level about 20 meters in two to five centuries and is thought to have influenced the start of the Bølling / Allerød interstadial , the major break with glacial cold in the Northern Hemisphere . Meltwater pulse 1A was followed in Antarctica and the Southern Hemisphere by a renewed cooling , the Antarctic Cold Reversal , in c. 14,500 BP , which lasted for two millennia -- an instance of warming causing cooling . The ACR brought an average cooling of perhaps 3 ° C . The Younger Dryas cooling , in the Northern Hemisphere , began while the Antarctic Cold Reversal was still ongoing , and the ACR ended in the midst of the Younger Dryas .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions . They were preserved so well by quick freezing , which is taken as evidence of a rapid onset of a global blizzard or similar event .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years . Global temperatures increased by 5 -- 8 ° C . The carbon dioxide was likely released in two pulses , the first lasting less than 2,000 years . Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon . Stratigraphic sections of rock from this period reveal numerous other changes . Fossil records for many organisms show major turnovers .

The same effect also occurs over bodies of salt water , when it is termed ocean-effect or bay-effect snow . The effect is enhanced when the moving air mass is uplifted by the orographic influence of higher elevations on the downwind shores . This uplifting can produce narrow but very intense bands of precipitation , which deposit at a rate of many inches of snow each hour , often resulting in a large amount of total snowfall . The areas affected by lake-effect snow are called snowbelts .

For instance as oceans are warming and becoming more acidic, biodiversity is becoming reduced and changing currents will cause more frequent storms and droughts. Every year around 8 million metric tons of plastic waste leak into the ocean and make it into the circular ocean currents. This causes contamination of sediments at the sea-bottom and causes plastic waste to be embedded in the aquatic food chain. It could lead to oceans containing more plastics than fish by 2050 if nothing is done. Key habitats such as coral reefs are at risk and noise pollution are a threat to whales, dolphins, and other species. Furthermore almost 90 percent of fish stocks are overfished or fully exploited which cost more than $80 billion a year in lost revenues.UN Secretary-General António Guterres stated that decisive, coordinated global action can solve the problems created by Humanity. Peter Thomson, President of the UN General Assembly, highlighted the conference's significance, saying \"if we want a secure future for our species on this planet, we have to act now on the health of the ocean and on climate change\".The conference sought to find ways and urge for the implementation of Sustainable Development Goal 14.

Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth .

The most extreme tidal range occurs when the gravitational forces of both the Sun and Moon are aligned ( syzygy ) , reinforcing each other in the same direction ( new moon ) or in opposite directions ( full moon ) . This type of tide is known as a spring tide . During neap tides , when the Moon and Sun 's gravitational force vectors act in quadrature ( making a right angle to the Earth 's orbit ) , the difference between high and low tides is smaller .

Some shorelines experience a semi-diurnal tide -- two nearly equal high and low tides each day . Other locations experience a diurnal tide -- only one high and low tide each day . A `` mixed tide '' -- two uneven tides a day , or one high and one low -- is also possible . Tides vary on timescales ranging from hours to years due to a number of factors .

These data are compared to the reference ( or datum ) level usually called mean sea level . While tides are usually the largest source of short-term sea-level fluctuations , sea levels are also subject to forces such as wind and barometric pressure changes , resulting in storm surges , especially in shallow seas and near coasts .

Along many coastlines , the Moon contributes the major part ( 67 % ) of the combined lunar and solar tides . The exact interval between tides is influenced by the position of the Moon and Sun relative to the Earth , as well as the specific location on Earth where the tide is being measured . Due to the Moon 's orbital prograde motion , it takes a particular point on the Earth ( on average ) 24 hours and 50.5 minutes to rotate under the Moon , so the time between high lunar tides fluctuates between 12 and 13 hours . A tide clock is divided into two roughly 6-hour tidal periods that shows the average length of time between high and low tides in a semi-diurnal tide region , such as most areas of the Atlantic Ocean . Traditional Mechanical Tide Clocks : The bottom of the tide clock dial ( 6 o-clock position ) is marked `` low tide '' and the top of the tide clock dial ( 12 o'clock position ) is marked `` high tide . '' The left side of the dial is marked `` hours until high tide '' and has a count-down of hours from 5 to 1 . There is one hand on the clock face , and along the left side it points to the number of hours `` until '' the ( lunar ) high tide . The right hand side of the clock is marked `` hours until low tide '' and has a count-down of hours from 5 to 1 . The number pointed to by the hand gives the time `` until '' the ( lunar ) low tide . Some tide clocks incorporate time ( using standard quartz movement ) and even humidity and temperature in the same instrument . Some tide clocks count down the number of hours from high or low tide , as in `` one hour past high or low tide '' . When the clock reaches the half way point ( `` half-tide '' ) , it then counts the hours up to high tide or low tide , as in `` one hour until high or low tide '' . Generally , there is an adjustment knob on the back on the instrument which may be used to set the tide using official tide tables for a specific location at either high or low tide . Tides have an inherent lead or lag , known as the lunitidal interval , that is different at every location , so tidal clocks are set for the time when the local lunar high tide occurs . This is often complicated because the lead or lag varies during the course of the lunar month , as the lunar and solar tides fall into and out of synchronization . The lunar tide and solar tide are synchronized ( ebb and flow at the same time ) near the full moon and the new moon . The two tides are unsynchronized near the first and last quarter moon ( or `` half moon '' ) . Also , in addition to the relative position of the moon and the elliptical pattern of the sun , the tide can be affected to some degree by wind and atmospheric pressure . All of these variables have less impact on the tide at the time of the full moon , so this is usually the best time to set a tide clock . If the tide clock is mounted on a moving boat , it will need to be reset more frequently . The best time to set the clock is at the new moon or the full moon , which is also when the clock can most reliably indicate the actual combined tide . A simple tide clock will always be least reliable near the quarter moon . Tide range is the vertical distance between the highest high tide and lowest low tide . The size of the lunar tide compared to the solar tide ( which comes once every 12 hours ) is generally about 2 to 1 , but the actual proportion along any particular shore depends on the location , orientation , and shape of the local bay or estuary . Along some shorelines , the solar tide is the only important tide , and ordinary 12-hour clocks suffice since the high and low tides come at nearly the same time every day . Because ordinary tidal clocks only track a part of the tidal effect , and because the relative size of the combined effects is different in different places , they are in general only partially accurate for tracking the tides . Consequently , all navigators use tide tables either in a booklet , computer or digital tide clock . Analog tide clocks are most accurate for use on the Atlantic coasts of America and Europe . This is because along the Atlantic coastline the moon controls the tides predictably , ebbing and flowing on a regular ( 12 - to 13-hour ) schedule . However , in other parts of the world such as along the Pacific Coast , tides can be irregular . The Pacific Ocean is so vast that the moon can not control the entire ocean at once . The result is that parts of the Pacific Coast can have 3 high tides a day . Similarly , there are areas in the world like the Gulf of Mexico or the South China Sea that have only one high tide a day . Mechanical tide clocks used on the Pacific Coast must be adjusted frequently , often as much as weekly , and are not useful in diurnal areas ( those with one tide per day ) . Digital Tide Clocks : Digital tide clocks are not married to the 24 hour 50.5 minute tide cycle and thus track tides beyond the Atlantic coast . Smart digital tide clocks can work across all locations in North America without any adjustments . This is achieved by storing all the variations of tides at numerous locations . Given a particular location and date/time , a digital tide clock can display the previous tide , next tide and current absolute tide height .

It was invented in 1874 by Herbert McLeod ( 1841 -- 1923 ) . McLeod gauges were once commonly found attached to equipment that operates under vacuum , such as a lyophilizer . Today , however , these gauges have largely been replaced by electronic vacuum gauges . The design of a McLeod gauge is somewhat similar to a that of a mercury-column manometer . Typically it is filled with mercury . If used incorrectly , this mercury can escape and contaminate the vacuum system attached to the gauge . McLeod gauges operate by taking in a sample volume of gas from a vacuum chamber , then compressing it by tilting and infilling with mercury . The pressure in this smaller volume is then measured by a mercury manometer , and knowing the compression ratio ( the ration of the initial and final volumes ) , the pressure of the original vacuum can be determined by applying Boyle 's law . This method is fairly accurate for non-condensible gases , such as oxygen and nitrogen . However , condensible gases , such as water vapour , ammonia , carbon dioxide , and pump-oil vapors may be in gaseous form in the low pressure of the vacuum chamber , but will condense when compressed by the McLeod gauge . The result is an erroneous reading , showing a pressure much lower than actually present . A cold trap may be used in conjunction with a McLeod gauge to condense these vapors before they enter the gauge . The McLeod gauge has the advantage that it is simple to use and that its calibration is nearly the same for all non-condensable gases . The device can be manually operated and the scale read visually , or the process can be automated in various ways . For example , a small electric motor can periodically rotate the assembly to collect a gas sample . If a fine platinum wire is in the capillary tube , its resistance indicates the height of the mercury column around it . Modern electronic vacuum gauges are simpler to use , less fragile , and do not present a mercury hazard , but their reading is highly dependent on the chemical nature of the gas being measured , and their calibration is unstable . For this reason , McLeod gauges continue to be used as a calibration standard for electronic gauges .", "qid": "626", "docid": "McLeod_gauge", "rank": 13, "score": 89360 }, { "content": "Title: Lunitidal interval Content: The lunitidal interval , measures the time lag from the Moon passing overhead , to the next high or low tide . It is also called the high water interval ( HWI ) . Sometimes a term is not used for the time lag , but instead the terms age of the tide or the establishment of the tide are used for the entry that is in the tidal tables . Tides are known to be mainly caused by the Moon 's gravity . Theoretically , peak tidal forces at a given location would concur when the Moon reaches the meridian , but a delay usually precedes high tide , depending largely on the shape of the coastline and the sea floor . Therefore , the lunitidal interval varies from place to place -- from 3 hours over deep oceans to 8 hours at New York Harbor . The lunitidal interval further varies within about + / -30 minutes according to the lunar phase . ( This is caused by the time interval associated with the solar tides . ) Hundreds of factors are involved in the lunitidal interval , especially near the shoreline . However , for those far away enough from the coast , the dominating consideration is the speed of gravity waves , which increases with the water 's depth . ( It is proportional to the square root of the depth , for the extremely long gravity waves that transport the water that is following the Moon around the Earth . The oceans are about 4 km deep and would have to be at least 22 km deep for these waves to keep up with the Moon . As mentioned above , a similar time lag accompanies the solar tides , a complicating factor that varies with the lunar phases . ) By observing the age of leap tides , it becomes clear that the delay can actually exceed 24 hours in some locations . The approximate lunitidal interval can be calculated if the moonrise , moonset , and high tide times are known for a location . In the Northern Hemisphere , the Moon reaches its highest point when it is southernmost in the sky . Lunar data are available from printed or online tables . Tide tables forecast the time of the next high water . The difference between these two times is the lunitidal interval .

Its purpose was to shorten the laborious and error-prone computations of tide-prediction . Such machines usually provided predictions valid from hour to hour and day to day for a year or more ahead . The first tide-predicting machine , designed and built in 1872-3 , and followed by two larger machines on similar principles in 1876 and 1879 , was conceived by Sir William Thomson ( who later became Lord Kelvin ) . Thomson had introduced the method of harmonic analysis of tidal patterns in the 1860s and the first machine was designed by Thomson with the collaboration of Edward Roberts ( assistant at the UK HM Nautical Almanac Office ) , and of Alexander Légé , who constructed it . In the US , another tide-predicting machine on a different pattern ( shown right ) was designed by William Ferrel and built in 1881-2 . Developments and improvements continued in the UK , US and Germany through the first half of the 20th century . The machines became widely used for constructing official tidal predictions for general marine navigation . They came to be regarded as of military strategic importance during World War I , and again during the second World War , when the US No. 2 Tide Predicting Machine , described below , was classified , along with the data that it produced , and used to predict tides for the D-day Normandy landings and all the island landings in the Pacific war . Military interest in such machines continued even for some time afterwards . They were made obsolete by digital electronic computers that can be programmed to carry out similar computations , but the tide-predicting machines continued in use until the 1960s and 1970s .

It arises because the gravitational force exerted by one body on another is not constant across it : the nearest side is attracted more strongly than the farthest side . Thus , the tidal force is differential . Consider the gravitational attraction of the Moon on the oceans nearest to the Moon , the solid Earth and the oceans farthest from the Moon . There is a mutual attraction between the Moon and the solid Earth , which can be considered to act on its centre of mass . However , the near oceans are more strongly attracted and , especially since they are fluid , they approach the Moon slightly , causing a high tide . The far oceans are attracted less . The attraction on the far-side oceans could be expected to cause a low tide , but since the solid Earth is attracted ( accelerated ) more strongly towards the moon , there is a relative acceleration of those waters in the outwards direction . Viewing the Earth as a whole , we see that all its mass experiences a mutual attraction with that of the Moon , but the near oceans more so than the far oceans , leading to a separation of the two . In a more general usage in celestial mechanics , the expression `` tidal force '' can refer to a situation in which a body or material ( for example , tidal water ) is mainly under the gravitational influence of a second body ( for example , the Earth ) , but is also perturbed by the gravitational effects of a third body ( for example , the Moon ) . The perturbing force is sometimes in such cases called a tidal force ( for example , the perturbing force on the Moon ) : it is the difference between the force exerted by the third body on the second and the force exerted by the third body on the first .", "qid": "626", "docid": "Tidal_force", "rank": 30, "score": 83313 }, { "content": "Title: Weather gage Content: The weather gage ( sometimes spelled weather gauge ) is the advantageous position of a fighting sailing vessel relative to another . The concept is from the Age of Sail , and is now largely antiquated . A ship at sea is said to possess the weather gage if it is in any position upwind of the other vessel . Close proximity with the land , tidal and stream effects , and wind variability due to geography ( hills , cliffs , etc. ) may also come into play . An upwind vessel is able to manoeuvre at will toward any downwind point , since in doing so the relative wind moves aft . A vessel downwind of another , however , in attempting to attack upwind , is constrained to trim sail as the relative wind moves forward and can not point too far into the wind for fear of being headed . In sailing warfare , when beating to windward , the vessel experiences heeling under the sideward pressure of the wind . This restricts gunnery , as cannon on the windward side are now elevated , while the leeward gun ports aim into the sea , or in heavy weather may be awash . A ship with the weather gage , turning downwind to attack , may alter course at will in order to bring starboard and port guns to appropriate elevations . Ships seeking to evade capture or attack , however , have the advantage being downwind if they are faster vessels or are close to friendly land . The term has had a literary rebirth in the popular seafaring novels of C.S. Forester , Patrick O'Brian , and Alexander Kent . One of the last times that weather gage was perhaps a factor in a naval engagement was in the Battle of the Denmark Strait in 1941 where the German battleship Bismarck and the heavy cruiser Prinz Eugen held the weather gage over the British battleship HMS Prince of Wales and the battlecruiser . Being upwind , the German ships had the advantage that their rangefinders were not as wet as the British rangefinders , which faced the spray direction . The weather restricted the visual range to much less than the gun range . In the end , being upwind from one 's target was not an advantage for the Germans -- it was even detrimental . The common tactic was to bypass the thick armor of a ship 's hull , making the shells dive almost vertically over the less-protected horizontal decks . Firing against the wind would make the shells fall more vertically , given their parabolic trajectories . The concept of weather gage is still useful in modern yacht racing , although it is hardly ever referred to by that name . The sails of a boat disrupt the wind to leeward ; this disruption is often called `` dirt '' or `` dirty air '' . An overtaking boat on a downwind course can position itself to focus its dirty air on the boat ahead of it . Conversely , a boat on an upwind course may find itself trapped in the dirty air of a boat immediately to windward . However , right-of-way rules give priority to the leeward boat and can make it advantageous to be the boat without the weather gage , especially just before the start or when the boat to leeward can point higher into the wind .", "qid": "626", "docid": "Weather_gage", "rank": 31, "score": 83157 }, { "content": "Title: Rule of twelfths Content: The rule of twelfths is an approximation to a sine curve .

The distance between a reference point on the surface of the Earth relative to these objects can be expressed as an infinite combination of periods and , as the distance changes , so does the tidal forcing . An analysis of the changing distance by Pierre-Simon de Laplace in the 18th century shows that these periods at which gravity varies cluster into three species , the semi-diurnal and diurnal tide constituents which have periods of a day or less , and the long period tidal constituents ( see also tide ) . Long period tidal constituents with relatively strong forcing include the lunar fortnightly ( Mf ) and monthly ( Ms ) as well as the solar semiannual ( Ssa ) and annual ( Sa ) constituents . In addition to having periods longer than a day-long period tidal forcing is distinguished from that of the first and second species by being zonally symmetric .

As their popularity grew , the group performed alongside their Michigan contemporaries the Unrelated Segments , MC5 , and SRC , among others . Tom and John Wearing arranged an audition with record producer John Chekaway , a relative of the two band members . Chekaway was impressed by the Tidal Waves and signed the group to his Detroit-based record label , SVR Records . The Tidal Waves raised the $ 200 required to record at the United Sound Systems Studios on January 7 , 1966 , cutting a cover version of Don and Dewey 's tune , `` Farmer John '' , and the original song by Witkowski , `` She Left Me All Alone '' , on a Scully 4-track for their debut single . The records were co-produced by Chekaway and Richard Cioffari . Originally , 1,000 copies of `` Farmer John '' were pressed , and charted in several Michigan radio station charts , including number five on WXYZ , number six on WKNR , and number one on WTRX . Chekaway could not afford to keep issuing more copies of the single , so he signed the Tidal Waves ' recording contract over to Hanna-Barbera Records , who distributed 50,000 copies of `` Farmer John '' across the US and the UK .

Multiple music artists changed their social media profiles design blue , and posted the phrase '' #TIDALforAll '' on Facebook , Twitter and Instagram . A press conference took place on March 30 , 2015 , introducing sixteen music artists to the stage , including Jay Z , who were all co-owners and stakeholders in Tidal . The service was promoted as being the first artist-owned streaming service with the goal of returning the value proposition to music . While some observers praised the impressive high fidelity , lossless audio quality , and the higher subscription fees which would result in higher royalties to the artists and songwriters , others felt the high subscription fees and exclusive Tidal content from the artists involved could result in an increase of music piracy . As of March 2015 , the service itself claims to have over 580,000 paying users after being integrated with its sister service , WiMP , as well as 17,000 using the high fidelity service .

These points are sometimes called tidal nodes . The term amphidromic point derives from the Greek words amphi ( around ) and dromos ( running ) , referring to the rotary tides running around them .

At the amphidromic points of the dominant tidal constituent , there is almost no vertical movement from tidal action . There can be tidal currents since the water levels on either side of the amphidromic point are not the same . A separate amphidromic system is created by each periodic tidal component .

It is also known as Page 's trend test or Page 's L test . It is a repeated measure trend test . The Page test is useful where : there are three or more conditions , a number of subjects ( or other randomly sampled entities ) are all observed in each of them , and we predict that the observations will have a particular order . For example , a number of subjects might each be given three trials at the same task , and we predict that performance will improve from trial to trial . A test of the significance of the trend between conditions in this situation was developed by Page ( 1963 ) . More formally , the test considers the null hypothesis that , for n conditions , where mi is a measure of the central tendency of the ith condition , against the alternative hypothesis that It has more statistical power than the Friedman test against the alternative that there is a difference in trend . Friedman 's test considers the alternative hypothesis that the central tendencies of the observations under the n conditions are different without specifying their order . Procedure for the Page test , with k subjects each exposed to n conditions : Arrange the n conditions in the order implied by the alternative hypothesis , and assign each of them a rank Yi . For each of the k subjects separately , rank the n observations from 1 to n. Add the ranks for each condition to give a total Xi . Multiply Xi by Yi and add all the products together ; this sum is called L. To test whether there is a significant trend , values of L can be compared with those tabulated by Page ( 1963 ) . Alternatively , the quantity may be compared with values of the chi-squared distribution with one degree of freedom . This gives a two-tailed test . The approximation is reliable for more than 20 subjects with any number of conditions , for more than 12 subjects when there are 4 or more conditions , and for any number of subjects when there are 9 or more conditions . If a measure of the overall correlation between the conditions and the data is required , it can be calculated as ρ = 12L/k ( n3 − n ) − 3 ( n + 1 ) / ( n − 1 ) if k = 1 , this reduces to the familiar Spearman coefficient . The Page test is most often used with fairly small numbers of conditions and subjects . The minimum values of L for significance at the 0.05 level , one-tailed , with three conditions , are 56 for 4 subjects ( the lowest number that is capable of giving a significant result at this level ) , 54 for 5 subjects , 91 for 7 subjects , 128 for 10 subjects , 190 for 15 subjects and 251 for 20 subjects .

In connection with earthquakes , syzygy refers to the idea that the combined tidal effects of the sun and moon -- either directly as earth tides in the crust itself , or indirectly by hydrostatic loading due to ocean tides -- should be able to trigger earthquakes in rock that is already stressed to the point of fracturing , and therefore more earthquakes should occur at times of maximal tidal stress , such as at the new and full moons . Indeed , recent work has concluded that `` large earthquakes are more probable during periods of high tidal stress '' . Previously , scientists have searched for such a correlation for over a century , but with the exception of volcanic areas ( including mid-ocean spreading ridges ) the results have been mixed . It has been suggested that some negative results are due to failure to account for tidal phase and fault orientation ( dip ) , while `` many studies reporting positive correlations suffer from a lack of statistical rigor . '' One systematic investigation found `` no evidence for an increase in seismicity during intervals of large tidal range but there is clear evidence for small but significant increase in earthquake rates near low tide '' ; it did not find an increase of earthquakes near peak spring tides . Seismicity is favored at low tides , particularly for reverse faults , because unloading unclamps the fault , reducing friction . Ocean loading has no effect at all on strike-slip faults .

Many sources state that regelation can be demonstrated by looping a fine wire around a block of ice , with a heavy weight attached to it . The pressure exerted on the ice slowly melts it locally , permitting the wire to pass through the entire block . The wire 's track will refill as soon as pressure is relieved , so the ice block will remain solid even after wire passes completely through . This experiment is possible for ice at − 10 ° C or cooler , and while essentially valid , the details of the process by which the wire passes through the ice are complex . The phenomenon works best with high thermal conductivity materials such as copper , since latent heat of fusion from the top side needs to be transferred to the lower side to supply latent heat of melting . If 1 mm diameter wire is used , over an ice cube 50 mm wide , the area the force is exerted on is 50 mm2 . This is 50 × 10 − 6 m2 . Force ( in newtons ) equals pressure ( in pascals ) multiplied by area ( in square metres ) .

The rafting of various size sediments into deeper ocean waters by icebergs became a rather important process . Ice rafting is still a process occurring today although its impact is significantly less and much harder to gauge . The melting of large icebergs deposits sediment of various sizes , usually referred to as glacial marine sediment , onto the shelf and deeper marine areas . Ice rafting may be used for analysis of ice drift pattern by matching the rafted sediment with its origin .

Heinrich events are particularly well documented for the last glacial period but notably absent from the penultimate glaciation ( Obrochta et al. , 2014 ) . The icebergs contained rock mass , which has been eroded by the glaciers , and as they melted , this matter was dropped onto the sea floor as ice rafted debris ( abbreviated to `` IRD '' ) . The icebergs ' melting caused extensive amounts of fresh water to be added to the North Atlantic . Such inputs of cold and fresh water may well have altered the density-driven , thermohaline circulation patterns of the ocean , and often coincide with indications of global climate fluctuations .

A spring freshet can sometimes last several weeks on large river systems , resulting in significant inundation of flood plains as the snowpack melts in the river 's catchment area . Freshets occur with generally diminishing strength and duration depending upon the snowpacks having large accumulations and then the local average rates of warming temperatures ; late spring melts allowing faster flooding from the relatively longer days and higher solar angle against more southerly latitudes and elevations reaching average melting temperatures sooner where earlier and generally lesser seasonal snow piles melt more gradually spread over a longer melt period . Serious flooding from southern freshets are more often related to rain storms of large tropical weather systems rolling in from the South Atlantic or Gulf of Mexico , to add their powerful heating capacity to lesser snow packs . Tropically induced rainfall influenced quick melts can also affect snow cover to latitudes as far north as southern Canada , so long as the generally colder air mass is not blocking northward movement of low pressure systems .

Studied by glaciologists , the temporal coincidence of glacier retreat with the measured increase of atmospheric greenhouse gases is often cited as an evidentiary underpinning of global warming . Mid-latitude mountain ranges such as the Himalayas , Alps , Rocky Mountains , Cascade Range , and the southern Andes , as well as isolated tropical summits such as Mount Kilimanjaro in Africa , are showing some of the largest proportionate glacial losses . Glacier mass balance is the key determinant of the health of a glacier . If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance ; if the accumulation is less than the ablation , the glacier will retreat . Glaciers in retreat will have negative mass balances , and if they do not find an equilibrium between accumulation and ablation , will eventually disappear . The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the present . Subsequently , until about 1940 , glaciers around the world retreated as the climate warmed substantially . Glacial retreat slowed and even reversed temporarily , in many cases , between 1950 and 1980 as global temperatures cooled slightly . Since 1980 , a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous , so much so that some glaciers have disappeared altogether , and the existences of many of the remaining glaciers are threatened . In locations such as the Andes of South America and Himalayas in Asia , the demise of glaciers in these regions has the potential to affect water supplies in those areas . The retreat of mountain glaciers , notably in western North America , Asia , the Alps and tropical and subtropical regions of South America , Africa and Indonesia , provide evidence for the rise in global temperatures since the late 19th century . The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level , which would affect coastal regions .", "qid": "628", "docid": "Retreat_of_glaciers_since_1850", "rank": 78, "score": 82411 }, { "content": "Title: Skuleskogen National Park Content: Skuleskogen National Park ( Skuleskogens nationalpark ) is a Swedish national park in Västernorrland County , on the coast of the Baltic Sea , in northern Sweden .

The park is characterized by a very rough topology with many rocky peaks , of which the highest is Slåttdalsberget , 280 m in altitude , rising directly from the sea . The topography is also marked by the presence of deep crevasses and caves . This particular topology can be found throughout the entire High Coast ( Swedish : Höga kusten ) , a region of Sweden so named because it constitutes the highest section of the coast of the Baltic Sea . This region is in our day principally known as a favored site for the observation of the phenomenon of post-glacial rebound . Most of the region was under the sea less than 10,000 years ago , after the ice sheet that blanketed it melted . But thanks to the melting of this mass of ice that had been pressing down upon it , the ground is rising year by year , at a current speed of 8 mm per year . Humans have left their mark upon the park , although they probably never established themselves there in great numbers . Numerous Bronze Age funerary cairns are still visible along the ancient coastline . Later , the forest was mainly used as pasture . Things changed in the middle of the 19th century when the logging industry spread throughout Sweden , affecting almost all the forest of the park . This exploitation ceased , however , at the end of that century , so that the current forest is dominated by trees more than 100 years old . This forest has thus been able to recover a part of its ancestral richness , and so contains an important fauna and flora , with several endangered species , such as the lichen Dolichousnea longissima , which is the park 's symbol . This geological and biological richness led to the creation of a national park in 1984 , followed by the inclusion of the park with the rest of the High Coast in 2000 in the UNESCO World Heritage List .

Glaciers slowly deform and flow due to stresses induced by their weight , creating crevasses , seracs , and other distinguishing features . They also abrade rock and debris from their substrate to create landforms such as cirques and moraines . Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water . On Earth , 99 % of glacial ice is contained within vast ice sheets in the polar regions , but glaciers may be found in mountain ranges on every continent except Australia , and on a few high-latitude oceanic islands . Between 35 ° N and 35 ° S , glaciers occur only in the Himalayas , Andes , Rocky Mountains , a few high mountains in East Africa , Mexico , New Guinea and on Zard Kuh in Iran .

Ordinary water ice is known as ice Ih , ( in the Bridgman nomenclature ) . Different types of ice , from ice II to ice XVI , have been created in the laboratory at different temperatures and pressures . Ice VII is metastable over a wide range of temperatures and pressures and transforms into low-density amorphous ice ( LDA ) above 120K . Ice VII has a triple point with liquid water and ice VI at 355 K and 2.216 GPa , with the melt line extending to at least 715 K and 10 GPa . It can also be created by increasing the pressure on ice VI at ambient temperature . Like the majority of ice phases ( including ice Ih ) , the hydrogen atom positions are disordered . In addition , the oxygen atoms are disordered over multiple sites . The structure of ice VII comprises a hydrogen bond framework in the form of two interpenetrating ( but non-bonded ) sublattices . Hydrogen pass through the center of the water hexamers and thus do not connect the two lattices . Ice VII has a density of about 1.65 g cm − 3 ( at 2.5 GPa and 25 ° C ) , which is less than twice the cubic ice density as the intra-network O -- O distances are 8 % longer ( at 0.1 MPa ) to allow for interpenetration .

According to Bergeron , most precipitation is formed as a consequence of water evaporating from small supercooled droplets and accreting onto ice crystals , which then fall as snow , or melt and fall as cold rain depending on the ambient air temperature . This process is known as the Bergeron Process , and is believed to be the primary process by which precipitation is formed . Bergeron was one of the principal scientists in the Bergen School of Meteorology , which transformed this science by introducing a new conceptual foundation for understanding and predicting weather . While developing innovative methods of forecasting , the Bergen scientists established the notion of weather fronts and elaborated a new model of extratropical cyclones that accounted for their birth , growth , and decay . Bergeron is credited with discovering the occlusion process , which marks the final stage in the life cycle of an extratropical cyclone .

The main forms of precipitation include drizzle , rain , sleet , snow , graupel and hail . Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor , so that the water condenses and `` precipitates '' . Thus , fog and mist are not precipitation but suspensions , because the water vapor does not condense sufficiently to precipitate . Two processes , possibly acting together , can lead to air becoming saturated : cooling the air or adding water vapor to the air . Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud . Short , intense periods of rain in scattered locations are called `` showers . '' Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain . This process is typically active when freezing rain is occurring . A stationary front is often present near the area of freezing rain and serves as the foci for forcing and rising air . Provided necessary and sufficient atmospheric moisture content , the moisture within the rising air will condense into clouds , namely stratus and cumulonimbus . Eventually , the cloud droplets will grow large enough to form raindrops and descend toward the Earth where they will freeze on contact with exposed objects . Where relatively warm water bodies are present , for example due to water evaporation from lakes , lake-effect snowfall becomes a concern downwind of the warm lakes within the cold cyclonic flow around the backside of extratropical cyclones . Lake-effect snowfall can be locally heavy . Thundersnow is possible within a cyclone 's comma head and within lake effect precipitation bands . In mountainous areas , heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation . On the leeward side of mountains , desert climates can exist due to the dry air caused by compressional heating . The movement of the monsoon trough , or intertropical convergence zone , brings rainy seasons to savannah climes . Precipitation is a major component of the water cycle , and is responsible for depositing the fresh water on the planet . Approximately 505000 km3 of water falls as precipitation each year ; 398000 km3 of it over the oceans and 107000 km3 over land . Given the Earth 's surface area , that means the globally averaged annual precipitation is 990 mm , but over land it is only 715 mm . Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes .

The reverse of deposition is sublimation and hence sometimes deposition is called desublimation . One example of deposition is the process by which , in sub-freezing air , water vapor changes directly to ice without first becoming a liquid . This is how snow forms in clouds , as well as how frost and hoar frost form on the ground or other surfaces . Another example is when frost forms on a leaf . For deposition to occur , thermal energy must be removed from a gas . When the leaf becomes cold enough , water vapor in the air surrounding the leaf loses enough thermal energy to change into a solid . Even though the air temperature may be below the dew point , the water vapor may not be able to condense spontaneously if there is no way to remove the latent heat . When the leaf is introduced , the supercooled water vapor immediately begins to condense , but by this point is already past the freezing point . This causes the water vapor to change directly into a solid . Another example is the soot that is deposited on the walls of chimneys . Soot molecules rise from the fire in a hot and gaseous state . When they come into contact with the walls they cool , and change to the solid state , without formation of the liquid state . The process is made use of industrially in combustion chemical vapor deposition . There is an industrial coatings process , known as evaporative deposition , whereby a solid material is heated to the gaseous state in a low-pressure chamber , the gas molecules travel across the chamber space and then condense to the solid state on a target surface , forming a smooth and thin layer on the target surface .

Steam produced in a boiler is another example of evaporation occurring in a saturated vapor phase . Evaporation that occurs directly from the solid phase below the melting point , as commonly observed with ice at or below freezing or moth crystals ( napthalene or paradichlorobenzene ) , is called sublimation . On average , a fraction of the molecules in a glass of water have enough heat energy to escape from the liquid . The reverse also happens -- water molecules from the air enter the water in the glass -- but as long as the relative humidity of the air in contact is less than 100 % ( i.e. , saturation ) , the net transfer of water molecules will be to the air . The water in the glass will be cooled by the evaporation until an equilibrium is reached where the air supplies the amount of heat removed by the evaporating water . In an enclosed environment the water would evaporate until the air is saturated . With sufficient temperature , the liquid would turn into vapor quickly ( see boiling point ) . When the molecules collide , they transfer energy to each other in varying degrees , based on how they collide . Sometimes the transfer is so one-sided for a molecule near the surface that it ends up with enough energy to `` escape '' and enter the surrounding air .

A shaft of precipitation which does n't evaporate before reaching the ground is a precipitation shaft .

It is very common in the desert and in temperate climates . In North America , it is commonly seen in the Western United States and the Canadian Prairies . It is also very common in the Middle East , Australia and North Africa . Virga can cause varying weather effects , because as rain is changed from liquid to vapor form , it removes heat from the air due to the high heat of vaporization of water . Precipitation falling into these cooling down drafts may eventually reach the ground . In some instances , these pockets of colder air can descend rapidly , creating a wet or dry microburst which can be extremely hazardous to aviation . Conversely , precipitation evaporating at high altitude can compressionally heat as it falls , and result in a gusty downburst which may substantially and rapidly warm the surface temperature . This fairly rare phenomenon , a heat burst , also tends to be of exceedingly dry air . Virga also has a role in seeding storm cells whereby small particles from one cloud are blown into neighboring supersaturated air and act as nucleation particles for the next thunderhead cloud to begin forming .

This condensation temperature depends on the volatile substance and the partial pressure of vapor in the protostar nebula . The actual temperature and distance for the snow line of water ice depend on the physical model used to calculate it and on the theoretical solar nebula model : 170 K at 2.7 AU ( Hayashi , 1981 ) 143 K at 3.2 AU to 150 K at 3 AU ( Podolak and Zucker , 2010 ) 3.1 AU ( Martin and Livio , 2012 ) ≈ 150 K for μm-size grains and ≈ 200 K for km-size bodies ( D'Angelo and Podolak , 2015 ) The radial position of the condensation/evaporation front varies over time , as the nebula evolves . Occasionally , the term snow line is also used to represent the present distance at which water ice can be stable ( even under direct sunlight ) . This current snow line distance is different from the formation snow line distance during the formation of Solar System , and approximately equals 5 AU . The reason for the difference is that during the formation of Solar System , the solar nebula was an opaque cloud where temperature were lower close to the Sun , and the Sun itself was less energetic . After formation , the ice got buried by infalling dust and it has remained stable a few meters below the surface . If ice within 5 AU is exposed , e.g. by a crater , then it sublimates on short timescales . However , out of direct sunlight ice can remain stable on the surface of asteroids ( and the Moon ) if it is located in permanently shadowed craters , where temperature may remain very low over the age of the Solar System ( e.g. 30 -- 40 K on the Moon ) . Observations of the asteroid belt , located between Mars and Jupiter , suggest that the water snow line during formation of Solar System was located within this region . The outer asteroids are icy C-class objects ( e.g. Abe et al. 2000 ; Morbidelli et al. 2000 ) whereas the inner asteroid belt is largely devoid of water . This implies that when planetesimal formation occurred the snow line was located at around 2.7 AU from the Sun . For example , the dwarf planet Ceres with semi-major axis of 2.77 AU lies almost exactly on the lower estimation for water snow line during the formation of the Solar System . Ceres appears to have an icy mantle and may even have a water ocean below the surface . Each volatile substance has its own snow line , e.g. carbon monoxide and nitrogen , so it is important to always specify which material 's snow line is meant . The lower temperature in the nebula beyond the frost line makes many more solid grains available for accretion into planetesimals and eventually planets . The frost line therefore separates terrestrial planets from giant planets in the Solar System . However , giant planets have been found inside the frost line around several other stars ( so-called hot Jupiters ) . They are thought to have formed outside the frost line , and later migrated inwards to their current positions . Earth , which lies less than a quarter of the distance to the frost line but is not a giant planet , has adequate gravitation for keeping methane , ammonia , and water vapor from escaping it . Methane and ammonia are rare in the Earth 's atmosphere only because of their instability in an oxygen-rich atmosphere that results from life forms ( largely green plants ) whose biochemistry suggests plentiful methane and ammonia at one time , but of course liquid water and ice , which are chemically stable in such an atmosphere , form much of the surface of Earth . Researchers Rebecca Martin and Mario Livio have proposed that asteroid belts may tend to form in the vicinity of the frost line , due to nearby giant planets disrupting planet formation inside their orbit . By analysing the temperature of warm dust found around some 90 stars , they concluded that the dust ( and therefore possible asteroid belts ) was typically found close to the frost line .

Ice lenses play the key role in frost induced heaving of soils and fracture of bedrock , which are fundamental to weathering in cold regions . Frost heaving creates debris and dramatically shapes landscapes into complex patterns . Rock fracture in periglacial regions ( alpine , subpolar and polar ) has often been attributed to the freezing and volumetric expansion of water trapped within pores and cracks .

Water strictly refers to the liquid state of that substance , that prevails at standard ambient temperature and pressure ; but it often refers also to its solid state ( ice ) or its gaseous state ( steam or water vapor ) . It also occurs in nature as snow , glaciers , ice packs and icebergs , clouds , fog , dew , aquifers , and atmospheric humidity . Water covers 71 % of the Earth 's surface . It is vital for all known forms of life . On Earth , 96.5 % of the planet 's crust water is found in seas and oceans , 1.7 % in groundwater , 1.7 % in glaciers and the ice caps of Antarctica and Greenland , a small fraction in other large water bodies , and 0.001 % in the air as vapor , clouds ( formed of ice and liquid water suspended in air ) , and precipitation . Only 2.5 % of this water is freshwater , and 98.8 % of that water is in ice ( excepting ice in clouds ) and groundwater . Less than 0.3 % of all freshwater is in rivers , lakes , and the atmosphere , and an even smaller amount of the Earth 's freshwater ( 0.003 % ) is contained within biological bodies and manufactured products . A greater quantity of water is found in the earth 's interior . Water on Earth moves continually through the water cycle of evaporation and transpiration ( evapotranspiration ) , condensation , precipitation , and runoff , usually reaching the sea . Evaporation and transpiration contribute to the precipitation over land . Large amounts of water are also chemically combined or adsorbed in hydrated minerals . Safe drinking water is essential to humans and other lifeforms even though it provides no calories or organic nutrients . Access to safe drinking water has improved over the last decades in almost every part of the world , but approximately one billion people still lack access to safe water and over 2.5 billion lack access to adequate sanitation . There is a clear correlation between access to safe water and gross domestic product per capita . However , some observers have estimated that by 2025 more than half of the world population will be facing water-based vulnerability . A report , issued in November 2009 , suggests that by 2030 , in some developing regions of the world , water demand will exceed supply by 50 % . Water plays an important role in the world economy . Approximately 70 % of the freshwater used by humans goes to agriculture . Fishing in salt and fresh water bodies is a major source of food for many parts of the world . Much of long-distance trade of commodities ( such as oil and natural gas ) and manufactured products is transported by boats through seas , rivers , lakes , and canals .

Studied by glaciologists , the temporal coincidence of glacier retreat with the measured increase of atmospheric greenhouse gases is often cited as an evidentiary underpinning of global warming . Mid-latitude mountain ranges such as the Himalayas , Alps , Rocky Mountains , Cascade Range , and the southern Andes , as well as isolated tropical summits such as Mount Kilimanjaro in Africa , are showing some of the largest proportionate glacial losses . Glacier mass balance is the key determinant of the health of a glacier . If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance ; if the accumulation is less than the ablation , the glacier will retreat . Glaciers in retreat will have negative mass balances , and if they do not find an equilibrium between accumulation and ablation , will eventually disappear . The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the present . Subsequently , until about 1940 , glaciers around the world retreated as the climate warmed substantially . Glacial retreat slowed and even reversed temporarily , in many cases , between 1950 and 1980 as global temperatures cooled slightly . Since 1980 , a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous , so much so that some glaciers have disappeared altogether , and the existences of many of the remaining glaciers are threatened . In locations such as the Andes of South America and Himalayas in Asia , the demise of glaciers in these regions has the potential to affect water supplies in those areas . The retreat of mountain glaciers , notably in western North America , Asia , the Alps and tropical and subtropical regions of South America , Africa and Indonesia , provide evidence for the rise in global temperatures since the late 19th century .

Sublimation is an endothermic process that occurs at temperatures and pressures below a substance 's triple point in its phase diagram . The reverse process of sublimation is deposition or desublimation , in which a substance passes directly from a gas to a solid phase . Sublimation has also been used as a generic term to describe a solid-to-gas transition ( sublimation ) followed by a gas-to-solid transition ( deposition ) . At normal pressures , most chemical compounds and elements possess three different states at different temperatures . In these cases , the transition from the solid to the gaseous state requires an intermediate liquid state . The pressure referred to is the partial pressure of the substance , not the total ( e.g. atmospheric ) pressure of the entire system . So , all solids that possess an appreciable vapor pressure at a certain temperature usually can sublimate in air ( e.g. water ice just below 0 ° C ) . For some substances , such as carbon and arsenic , sublimation is much easier than evaporation from the melt , because the pressure of their triple point is very high , and it is difficult to obtain them as liquids . The term sublimation refers to a physical change of state and is not used to describe transformation of a solid to a gas in a chemical reaction . For example , the dissociation on heating of solid ammonium chloride into hydrogen chloride and ammonia is not sublimation but a chemical reaction . Similarly the combustion of candles , containing paraffin wax , to carbon dioxide and water vapor is not sublimation but a chemical reaction with oxygen .

As outlined in numerous studies , erosional events along the margins of the Mediterranean Basin during the Messinian timespan , before and during the evaporite deposition , were common ( see a summary in van Dijk et al. , 1998 ) . These authors showed that also predating the deposition of the first cycle of evaporites , a major erosional phase can be observed along the basin margins , corresponding to a major `` relative sea level drop '' , associated with tectonic activity ( marking the end of the so-called `` Mes-1 '' unconformity bound depositional sequence ) . Following this assumption that this major event corresponds to the major Messinian drawdown , Bache et al. ( 2009 ) concluded that the Mediterranean bathymetry significantly decreased before the precipitation of central basins evaporites . Van Dijk et al. ( 1998 ) had baptised this end member scenario the `` Hunchback Scenario '' . Regarding these works , a deep water formation for central Messinian evaporites seems unlikely . The assumption that central basin evaporites partly deposited under a high bathymetry and before the major phase of erosion should imply the observation of a major detritic event above evaporites in the basin . Such a depositional geometry has not been observed on data , as the detrical wedges are merely confined to the basin marginal areas . Another major point of discussion regards the presence of erosional deep canyons along the continental margins of the Basins . These should be expected to be present because of the assumption of a major sea level drop . And in fact they have been described by several authors ( summarized in e.g. Clauzon et al. , 1996 ) . Most of them are infilled by early Pliocene sediments . As outlined in van Dijk et al. ( 1998 ) this phenomenon can be explained in two ways : A major eustatic sea level drop , or a tectonic uplift of the margins ( for example associated with a minor sea level drop ) . It constitutes , therefore , not a real proof for the desiccation of an existing originally deep basin . The third much disputed element is the recognition of the so-called `` MES '' , the Messinian Erosional Surface . This surface can well be traced in seismic sections along the Basin margins , showing angular and non-angular unconformities , somewhere within the evaporite deposits , or between evaporite and non-avaporite deposits . Nice examples are shown by Roveri et al. ( 2008 ) . As already extensively discussed in van Dijk ( 1992 ) , the erosional surfaces within the Messinian clastic and evaporitic and mixed series are often confused . Only very high resolution and complete series such as those in the Crotone Basin in Calabria can solve this matter , and the authors have shown that the erosional surfaces and there probable relationships with relative sea level fluctuations and tectonic activity can well be mapped ( see a review in van Dijk et al. , 1998 ) .", "qid": "630", "docid": "Messinian_erosional_crisis", "rank": 46, "score": 104137 }, { "content": "Title: Cirque glacier Content: A cirque glacier is formed in a cirque , a bowl-shaped depression on the side of or near mountains .

Rather , ice is blue for the same reason that large quantities of water are blue : it is a result of an overtone of an oxygen-hydrogen ( O-H ) bond stretch in water which absorbs light at the red end of the visible spectrum . In the case of oceans or lakes , some of the light , hitting the surface of water , is reflected back directly but most of it penetrates the surface interacting with its molecules . The water molecule can vibrate in different modes when light hits it . The red , orange , yellow , and green wavelengths of light are absorbed so that the remaining light is composed of the shorter wavelengths of blue and violet . This is the main reason why the ocean is blue . So , water owes its intrinsic blueness to selective absorption in the red part of its visible spectrum . The absorbed photons promote transitions to high overtone and combination states of the nuclear motions of the molecule , i.e. to highly excited vibrations .

The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases , especially carbon dioxide . When the global temperature changes , the changes in climate are not expected to be uniform across the Earth . In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores . Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years . There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere .

The only place where water ice is visible at the surface is at the north polar ice cap . Abundant water ice is also present beneath the permanent carbon dioxide ice cap at the Martian south pole and in the shallow subsurface at more temperate latitudes . More than five million cubic kilometers of ice have been identified at or near the surface of modern Mars , enough to cover the whole planet to a depth of 35 meters . Even more ice is likely to be locked away in the deep subsurface . Some liquid water may occur transiently on the Martian surface today , but only under certain conditions . No large standing bodies of liquid water exist , because the atmospheric pressure at the surface averages just 600 Pa -- about 0.6 % of Earth 's mean sea level pressure -- and because the global average temperature is far too low ( 210 K ) , leading to either rapid evaporation ( sublimation ) or rapid freezing . Before about 3.8 billion years ago , Mars may have had a denser atmosphere and higher surface temperatures , allowing vast amounts of liquid water on the surface , possibly including a large ocean that may have covered one-third of the planet . Water has also apparently flowed across the surface for short periods at various intervals more recently in Mars ' history . On December 9 , 2013 , NASA reported that , based on evidence from the Curiosity rover studying Aeolis Palus , Gale Crater contained an ancient freshwater lake that could have been a hospitable environment for microbial life . Many lines of evidence indicate that water is abundant on Mars and has played a significant role in the planet 's geologic history . The present-day inventory of water on Mars can be estimated from spacecraft imagery , remote sensing techniques ( spectroscopic measurements , radar , etc. ) , and surface investigations from landers and rovers . Geologic evidence of past water includes enormous outflow channels carved by floods , ancient river valley networks , deltas , and lakebeds ; and the detection of rocks and minerals on the surface that could only have formed in liquid water . Numerous geomorphic features suggest the presence of ground ice ( permafrost ) and the movement of ice in glaciers , both in the recent past and present . Gullies and slope lineae along cliffs and crater walls suggest that flowing water continues to shape the surface of Mars , although to a far lesser degree than in the ancient past . Although the surface of Mars was periodically wet and could have been hospitable to microbial life billions of years ago , the current environment at the surface is dry and subfreezing , probably presenting an insurmountable obstacle for living organisms . In addition , Mars lacks a thick atmosphere , ozone layer , and magnetic field , allowing solar and cosmic radiation to strike the surface unimpeded . The damaging effects of ionizing radiation on cellular structure is another one of the prime limiting factors on the survival of life on the surface . Therefore , the best potential locations for discovering life on Mars may be in subsurface environments . On November 22 , 2016 , NASA reported finding a large amount of underground ice on the planet Mars -- the volume of water detected is equivalent to the volume of water in Lake Superior . Understanding water on Mars is vital to assess the planet 's potential for harboring life and for providing usable resources for future human exploration . For this reason , ` Follow the Water ' was the science theme of NASA 's Mars Exploration Program ( MEP ) in the first decade of the 21st century . Discoveries by the 2001 Mars Odyssey , Mars Exploration Rovers ( MERs ) , Mars Reconnaissance Orbiter ( MRO ) , and Mars Phoenix lander have been instrumental in answering key questions about water 's abundance and distribution on Mars . The ESA 's Mars Express orbiter has also provided essential data in this quest .

Cooling tends to increase ice cover and hence the albedo , reducing the amount of solar energy absorbed and leading to more cooling . Conversely , warming tends to decrease ice cover and hence the albedo , increasing the amount of solar energy absorbed , leading to more warming .

Such holes are formed when the water temperature in the clouds is below freezing but the water , in a supercooled state , has not frozen yet due to the lack of ice nucleation . When ice crystals do form , a domino effect is set off due to the Bergeron process , causing the water droplets around the crystals to evaporate : this leaves a large , often circular , hole in the cloud . It is believed that the introduction of large numbers of tiny ice crystals into the cloud layer sets off this domino effect of fusion which creates the hole . The ice crystals can be formed by passing aircraft which often have a large reduction in pressure behind the wing - or propeller-tips . This cools the air very quickly , and can produce a ribbon of ice crystals trailing in the aircraft 's wake .

Mars probably had oceans in the past , and it definitely had lakes and a thicker atmosphere . Modern Mars has become cold , dry , and almost uninhabitable , yet , if life did ever arise on Mars , some hardy microbes and perhaps even multicellular life might survive there right through to the present . The only missions to search for life on Mars , the two Viking missions , returned results that were inconclusive . However the instruments were not designed to cope with the unusual conditions which Viking discovered on Mars , which may have confused the results of the experiments . Also , they did n't know enough about Mars at that time to target the regions we now think are most likely to have present day life . Life would meet many challenges on present day Mars . Liquid water boils at 0 ° C , over much of its surface . Even at the depths of the Hellas basin , any water is close to its boiling point of 10 ° C and will dry out quickly . Ice also evaporates into the atmosphere over geological timescales - and most of the equatorial regions are thought to be dry to depths of tens of meters . As its axial tilt varies , Mars atmosphere is sometimes thicker , and liquid water may then form on the surface - but any dormant life in the top few meters of soil would be destroyed over periods of millions of years by cosmic radiation . However , in 2008 , droplets were observed on the landing legs of Phoenix . Sadly , there was no way to analyse them , but the leading hypothesis is that they were droplets of salty water . Phoenix also made isotopic measurements which show that the Mars atmosphere has exchanged oxygen molecules with liquid on the surface in the recent geological past . This could indicate either recent episodic occurrences of liquid water ( for instance after a meteorite strike ) or water present every year , in contact with the atmosphere . We now know of many seasonal changes in the surface of Mars which are only visible in high resolution photographs . Most of these are now thought to be caused by dry ice or wind effects . However , the `` Recurrent slope lineae '' , and some of the `` flow like features '' form in conditions that suggest the occasional presence of small quantities of water on Mars . The evidence of flowing brines in the RSLs is strong , though it 's not known if they are habitable . Curiosity has also found indirect evidence of a brine layer 15 cm below the sands that it drives over , though most scientists think that this layer is not habitable for Earth life . Recent Mars surface simulations by Nilton Renno and his team have shown that small droplets of water can form on salt / ice interfaces for a few hours per day almost anywhere on the surface of Mars , and this may explain the Phoenix leg droplets observations . In a separate development , research by the German aerospace company DLR in Mars simulation chambers and on the ISS show that some Earth life can survive simulated Mars surface conditions without any water at all , and photosynthesize and metabolize , slowly . It can do this using the high relative humidity of the Mars atmosphere at night . All of this work was done after the Phoenix discoveries in 2008 . Other potential habitats include lakes formed in the higher latitudes after cometary or meteorite impacts , or as a result of volcanism . Covered by ice , these may remain liquid for centuries , or up to a few thousand years for the largest impacts . The planet may also have underground trapped layers of water heated by geothermal hotspots . Also there are suggestions that Mars may have a deep hydrosphere , a liquid layer below its cryosphere , a few kilometers below the surface . Deep rock habitats on Earth are inhabited by life so if this layer exists , it may also be habitable on Mars . The main questions are Do these potential habitats exist ? Are they habitable ? For instance , liquid water , if present , could be too cold , or too salty for Earth life Are they in fact inhabited by any forms of life ? As Mars is so inhospitable , life might not be able to spread to new habitats easily . So there might be life in some of the habitats and not in others . Or life on Mars may have gone extinct , or never evolved at all , in which case none of the habitats would be inhabited . These discoveries have renewed interest in this topic , with many astrobiologists saying that they think present day Mars may be more habitable than previously thought .

In much the same way that a watershed is defined by a topographically explicit area that provides surface runoff , the precipitationshed is a probabilistically defined area within which evaporation , traveling via moisture recycling , provides precipitation for a specific point .

Ordinary water ice is known as ice Ih , ( in the Bridgman nomenclature ) . Different types of ice , from ice II to ice XVI , have been created in the laboratory at different temperatures and pressures . Ice VII is metastable over a wide range of temperatures and pressures and transforms into low-density amorphous ice ( LDA ) above 120K . Ice VII has a triple point with liquid water and ice VI at 355 K and 2.216 GPa , with the melt line extending to at least 715 K and 10 GPa . It can also be created by increasing the pressure on ice VI at ambient temperature . Like the majority of ice phases ( including ice Ih ) , the hydrogen atom positions are disordered . In addition , the oxygen atoms are disordered over multiple sites . The structure of ice VII comprises a hydrogen bond framework in the form of two interpenetrating ( but non-bonded ) sublattices . Hydrogen pass through the center of the water hexamers and thus do not connect the two lattices . Ice VII has a density of about 1.65 g cm − 3 ( at 2.5 GPa and 25 ° C ) , which is less than twice the cubic ice density as the intra-network O -- O distances are 8 % longer ( at 0.1 MPa ) to allow for interpenetration . The cubic unit cell has a side length of 3.3501 Å ( for D2O , at 2.6 GPa and 22 ° C ) and contains two water molecules . Ice VII is the only disordered phase of ice that can be ordered by simple cooling , and it forms ( ordered ) ice VIII below 273 K up to ~ 8 GPa . Above this pressure , the VII -- VIII transition temperature drops rapidly , reaching 0 K at ~ 60 GPa . Thus , ice VII has the largest stability field of all of the molecular phases of ice . The cubic oxygen sub-lattices that form the backbone of the ice VII structure persist to pressures of at least 128 GPa ; this pressure is substantially higher than that at which water loses its molecular character entirely , forming ice X .

At the surface of the oceans towards the poles , seawater becomes cooler and more carbonic acid is formed as CO2 becomes more soluble . This is coupled to the ocean 's thermohaline circulation which transports dense surface water into the ocean 's interior ( see the entry on the solubility pump ) . Although the deep ocean contains much more dissolved inorganic carbon than the surface ocean , the concentration is only 15 % higher in the deep ocean as compared to the surface ocean due to the higher volume of the deep ocean . In upper ocean areas of high biological productivity , organisms convert reduced carbon to tissues , or carbonates to hard body parts such as shells and tests . These are , respectively , oxidized ( soft-tissue pump ) and redissolved ( carbonate pump ) at lower average levels of the ocean than those at which they formed , resulting in a downward flow of carbon ( see entry on the biological pump ) . The flux or absorption of carbon dioxide into the world 's oceans is influenced by the presence of widespread viruses within ocean water , that infect many species of bacteria . The resulting bacterial deaths spawn a sequence of events that lead to greatly enlarged respiration of carbon dioxide , enhancing the role of the oceans as a carbon sink . The balance of dissolved inorganic carbon ( DIC ) : dissolved organic carbon ( DOC ) : particle organic carbon is about 2000:38:1 . The CaCO3 counter pump increases the partial pressure of CO2 in the ocean , thus leading to higher outgasing of carbon dioxide .

The weathering of silicate rock ( see carbonate-silicate cycle ) . Carbonic acid reacts with weathered rock to produce bicarbonate ions . The bicarbonate ions produced are carried to the ocean , where they are used to make marine carbonates . Unlike dissolved CO2 in equilibrium or tissues , which decay , weathering does not move the carbon into a reservoir from which it can readily return to the atmosphere . Much remains to be learned about the cycling of carbon in the deep ocean . For example , a recent discovery is that larvacean mucus houses ( commonly known as `` sinkers '' ) are created in such large numbers that they can deliver as much carbon to the deep ocean as has been previously detected by sediment traps . Because of their size and composition , these houses are rarely collected in such traps , so most biogeochemical analyses have erroneously ignored them . The amount of dissolved inorganic carbon in the ocean is significantly higher in the deep layer ( below 300 m depth ) .

The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases , especially carbon dioxide . When the global temperature changes , the changes in climate are not expected to be uniform across the Earth . In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores . Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend .

Seawater is slightly basic ( meaning pH > 7 ) , and the process in question is a shift towards pH-neutral conditions rather than a transition to acidic conditions ( pH < 7 ) . Ocean alkalinity is not changed by the process , or may increase over long time periods due to carbonate dissolution . An estimated 30 -- 40 % of the carbon dioxide from human activity released into the atmosphere dissolves into oceans , rivers and lakes . To achieve chemical equilibrium , some of it reacts with the water to form carbonic acid . Some of these extra carbonic acid molecules react with a water molecule to give a bicarbonate ion and a hydronium ion , thus increasing ocean acidity ( H + ion concentration ) . Between 1751 and 1996 surface ocean pH is estimated to have decreased from approximately 8.25 to 8.14 , representing an increase of almost 35 % in H + ion concentration in the world 's oceans . Earth System Models project that within the last decade ocean acidity exceeded historical analogues and in combination with other ocean biogeochemical changes could undermine the functioning of marine ecosystems and disrupt the provision of many goods and services associated with the ocean . Increasing acidity is thought to have a range of potentially harmful consequences for marine organisms , such as depressing metabolic rates and immune responses in some organisms , and causing coral bleaching . By increasing the presence of free hydrogen ions , each molecule of carbonic acid that forms in the oceans ultimately results in the conversion of two carbonate ions into bicarbonate ions . This net decrease in the amount of carbonate ions available makes it more difficult for marine calcifying organisms , such as coral and some plankton , to form biogenic calcium carbonate , and such structures become vulnerable to dissolution . Ongoing acidification of the oceans threatens food chains connected with the oceans . As members of the InterAcademy Panel , 105 science academies have issued a statement on ocean acidification recommending that by 2050 , global emissions be reduced by at least 50 % compared to the 1990 level . While ongoing ocean acidification is anthropogenic in origin , it has occurred previously in Earth 's history . The most notable example is the Paleocene-Eocene Thermal Maximum ( PETM ) , which occurred approximately 56 million years ago .

Therefore , climate sensitivity depends on the initial climate state , but potentially can be accurately inferred from precise palaeoclimate data . Slow climate feedbacks , especially changes of ice sheet size and atmospheric CO2 , amplify the total Earth system sensitivity by an amount that depends on the time scale considered . Although climate sensitivity is usually used in the context of radiative forcing by carbon dioxide ( CO2 ) , it is thought of as a general property of the climate system : the change in surface air temperature ( ΔTs ) following a unit change in radiative forcing ( RF ) , and thus is expressed in units of ° C / ( W/m2 ) . For this to be useful , the measure must be independent of the nature of the forcing ( e.g. from greenhouse gases or solar variation ) ; to first order this is indeed found to be so . The climate sensitivity specifically due to is often expressed as the temperature change in ° C associated with a doubling of the concentration of carbon dioxide in Earth 's atmosphere . For coupled atmosphere-ocean global climate models ( e.g. CMIP5 ) the climate sensitivity is an emergent property : it is not a model parameter , but rather a result of a combination of model physics and parameters . By contrast , simpler energy-balance models may have climate sensitivity as an explicit parameter . The terms represented in the equation relate radiative forcing ( RF ) to linear changes in global surface temperature change ( ΔTs ) via the climate sensitivity λ .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

Southern Oscillation is the accompanying atmospheric component , coupled with the sea temperature change : El Niño is accompanied with high , and La Niña with low air surface pressure in the tropical western Pacific . The two periods last several months each ( typically occur every few years ) and their effects vary in intensity .

The Walker circulation is caused by the pressure gradient force that results from a high pressure system over the eastern Pacific Ocean , and a low pressure system over Indonesia . When the Walker circulation weakens or reverses , an El Niño results , causing the ocean surface to be warmer than average , as upwelling of cold water occurs less or not at all . An especially strong Walker circulation causes a La Niña , resulting in cooler ocean temperatures due to increased upwelling . Mechanisms that cause the oscillation remain under study .

It is particularly effective in reservoirs deeper than 2,500 ft. , where will be in a supercritical state , with API oil gravity greater than 22 -- 25 ° and remaining oil saturation greater than 20 % . It should also be noted that carbon dioxide flooding is not affected by the lithology of the reservoir area , but simply by the reservoir porosity and permeability , so that it is viable in both sandstone and carbonate reservoirs . By injecting CO2 into the reservoir , the viscosity of any hydrocarbon will be reduced and hence will be easier to sweep to the production well . As an oil field matures and production rates decline , there is growing incentive to intervene and attempt to increase oil output utilizing tertiary recovery techniques ( also termed improved or enhanced oil recovery ) . Petroleum engineers assess available options for increasing well productivity , options that include chemical injection , thermal/steam injection , and CO2 injection . Based on data-gathering and computer simulations , the most optimal enhanced oil-recovery technique to maximize well-productivity is determined . To increase the rate of oil production , the pressure within the reservoir must be increased . In CO2 flooding , the first step is injection of water into the reservoir , which will cause the reservoir pressure to increase . Once the reservoir has sufficient pressure , the next step is to pump the CO2 down through the same injection wells . The CO2 gas is forced into the reservoir to come into contact with the oil . This creates a miscible zone that can be moved more easily to the production well . Normally the CO2 injection is alternated with water injection and the water acts to sweep the oil towards the production zone . CO2 flooding is the second most common tertiary recovery technique and is used in facilities around the world .

The heat expelled by the magma expands the lithosphere and asthenosphere at the ridge , pushing them above the surrounding ocean floor . As time passes , the heated rocks cool and their density increases . When this happens gravity pulls the weighty lithosphere away from the mid-ocean ridge , down the sloping asthenosphere , which , in turn , allows new molten magma to well up . This fresh magma will eventually become new lithosphere . The cooling rock exerts a force on spreading lithospheric plates , helping to drive their movements . The force is called ridge push . It can be calculated by the principle of isostasy , making a balance between the mid-ocean ridge and the old ocean floor .

Mid-latitude mountain ranges such as the Himalayas , Alps , Rocky Mountains , Cascade Range , and the southern Andes , as well as isolated tropical summits such as Mount Kilimanjaro in Africa , are showing some of the largest proportionate glacial losses . Glacier mass balance is the key determinant of the health of a glacier . If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance ; if the accumulation is less than the ablation , the glacier will retreat . Glaciers in retreat will have negative mass balances , and if they do not find an equilibrium between accumulation and ablation , will eventually disappear . The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the present .

Glacial retreat slowed and even reversed temporarily , in many cases , between 1950 and 1980 as global temperatures cooled slightly .

More broadly , `` the sea '' is the interconnected system of Earth 's salty , oceanic waters -- considered as one global ocean or as several principal oceanic divisions . The sea moderates Earth 's climate and has important roles in the water cycle , carbon cycle , and nitrogen cycle . Although the sea has been traveled and explored since prehistory , the modern scientific study of the sea -- oceanography -- dates broadly to the British Challenger expedition of the 1870s . The sea is conventionally divided into up to five large oceanic sections -- including the International Hydrographic Organization 's four named oceans ( the Atlantic , Pacific , Indian , and Arctic ) and the Southern Ocean ; smaller , second-order sections , such as the Mediterranean , are known as seas . Owing to the present state of continental drift , the Northern Hemisphere is now fairly equally divided between land and sea ( a ratio of about 2:3 ) but the South is overwhelmingly oceanic ( 1:4.7 ) . Salinity in the open ocean is generally in a narrow band around 3.5 % by mass , although this can vary in more landlocked waters , near the mouths of large rivers , or at great depths . About 85 % of the solids in the open sea are sodium chloride . Deep-sea currents are produced by differences in salinity and temperature . Surface currents are formed by the friction of waves produced by the wind and by tides , the changes in local sea level produced by the gravity of the Moon and Sun . The direction of all of these is governed by surface and submarine land masses and by the rotation of the Earth ( the Coriolis effect ) . Former changes in sea levels have left continental shelves , shallow areas in the sea close to land . These nutrient-rich waters teem with life , which provide humans with substantial supplies of food -- mainly fish , but also shellfish , mammals , and seaweed -- which are both harvested in the wild and farmed . The most diverse areas surround great tropical coral reefs . Whaling in the deep sea was once common but whales ' dwindling numbers prompted international conservation efforts and finally a moratorium on most commercial hunting . Oceanography has established that not all life is restricted to the sunlit surface waters : even under enormous depths and pressures , nutrients streaming from hydrothermal vents support their own unique ecosystem . Life may have started there and aquatic microbial mats are generally credited with the oxygenation of Earth 's atmosphere ; both plants and animals first evolved in the sea .

The method is particularly well suited for quick system level response predictions at the early design stage of a product , and for predicting responses at higher frequencies . In SEA a system is represented in terms of a number of coupled subsystems and a set of linear equations are derived that describe the input , storage , transmission and dissipation of energy within each subsystem . The parameters in the SEA equations are typically obtained by making certain statistical assumptions about the local dynamic properties of each subsystem ( similar to assumptions made in room acoustics and statistical mechanics ) . These assumptions significantly simplify the analysis and make it possible to analyze the response of systems that are often too complex to analyze using other methods ( such as finite element and boundary element methods ) .", "qid": "634", "docid": "Statistical_energy_analysis", "rank": 22, "score": 80831 }, { "content": "Title: Seasat Content: Seasat was the first Earth-orbiting satellite designed for remote sensing of the Earth 's oceans and had on board the first spaceborne synthetic aperture radar ( SAR ) .

A `` mixed tide '' -- two uneven tides a day , or one high and one low -- is also possible . Tides vary on timescales ranging from hours to years due to a number of factors . To make accurate records , tide gauges at fixed stations measure water level over time . Gauges ignore variations caused by waves with periods shorter than minutes . These data are compared to the reference ( or datum ) level usually called mean sea level . While tides are usually the largest source of short-term sea-level fluctuations , sea levels are also subject to forces such as wind and barometric pressure changes , resulting in storm surges , especially in shallow seas and near coasts .

To search for periodicities in a single time series , the data sequence can be broken into separate subsets of equal duration , and then all subsets can be superposed .

To achieve this , the Sea Around Us presents fisheries and fisheries-related data at spatial scales that have ecological and policy relevance , such as by Exclusive Economic Zones , High Seas areas , or Large Marine Ecosystems . All spatialized data are visualized either graphically or mapped , and all data can be downloaded . Global fisheries catches from 1950 to the present are available , under explicit consideration of coral reefs , seamounts , estuaries and other critical habitats of fish and marine invertebrates . The data presented , which are all freely available , are meant to support studies of global fisheries trends and the development of sustainable , ecosystem-based fisheries policies . In the early 2000s , members of the Sea Around Us uncovered that China was overestimating its catches and showed that , when such distortions were removed from overall fisheries catches , global fisheries were actually declining since the late 1980s . The Sea Around Us also showed that the biomass of large fish in the North Atlantic is one-tenth of what it was only a century ago . Aquaculture , according to another study with members from the Project , can not be expected to compensate for overfishing but is instead likely to exacerbate the problem due to the reliance on wild fish for fishmeal . In other words , without serious long-term planning , the oceans might get a lot worse before they get better . In 2016 , members of the Sea Around Us , using reconstructed global catch data that combine officially reported landings data with comprehensive estimates of unreported landings and discards , documented that , from 1950-2010 , global catches were around 50 % higher than reported data suggest . Furthermore , total catches seem to be declining faster from their peak catch in the mid-1990s than reported data would suggest . The good news is that the discrepancy between reported data and estimated total catches is decreasing in more recent years , meaning that the comprehensiveness of data reported by countries seems to be improving . All this information was compiled in the Global Atlas of Marine Fisheries , a 520-page book published in October 2016 by Island Press .

The exact meaning of surface varies according to the measurement method used , but it is between 1 mm and 20 m below the sea surface . Air masses in the Earth 's atmosphere are highly modified by sea surface temperatures within a short distance of the shore . Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass . Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth 's oceans . Tropical cyclones can also cause a cool wake , due to turbulent mixing of the upper 30 m of the ocean . SST changes diurnally , like the air above it , but to a lesser degree . There is less SST variation on breezy days than on calm days . In addition , ocean currents such as the Atlantic Multidecadal Oscillation ( AMO ) , can effect SST 's on multi-decadal time scales , a major impact results from the global thermohaline circulation , which affects average SST significantly throughout most of the world 's oceans . Coastal SSTs can cause offshore winds to generate upwelling , which can significantly cool or warm nearby landmasses , but shallower waters over a continental shelf are often warmer . Onshore winds can cause a considerable warm-up even in areas where upwelling is fairly constant , such as the northwest coast of South America . Its values are important within numerical weather prediction as the SST influences the atmosphere above , such as in the formation of sea breezes and sea fog .

The most extreme tidal range occurs when the gravitational forces of both the Sun and Moon are aligned ( syzygy ) , reinforcing each other in the same direction ( new moon ) or in opposite directions ( full moon ) . This type of tide is known as a spring tide . During neap tides , when the Moon and Sun 's gravitational force vectors act in quadrature ( making a right angle to the Earth 's orbit ) , the difference between high and low tides is smaller .

More broadly , `` the sea '' is the interconnected system of Earth 's salty , oceanic waters -- considered as one global ocean or as several principal oceanic divisions . The sea moderates Earth 's climate and has important roles in the water cycle , carbon cycle , and nitrogen cycle . Although the sea has been traveled and explored since prehistory , the modern scientific study of the sea -- oceanography -- dates broadly to the British Challenger expedition of the 1870s . The sea is conventionally divided into up to five large oceanic sections -- including the International Hydrographic Organization 's four named oceans ( the Atlantic , Pacific , Indian , and Arctic ) and the Southern Ocean ; smaller , second-order sections , such as the Mediterranean , are known as seas . Owing to the present state of continental drift , the Northern Hemisphere is now fairly equally divided between land and sea ( a ratio of about 2:3 ) but the South is overwhelmingly oceanic ( 1:4.7 ) . Salinity in the open ocean is generally in a narrow band around 3.5 % by mass , although this can vary in more landlocked waters , near the mouths of large rivers , or at great depths . About 85 % of the solids in the open sea are sodium chloride . Deep-sea currents are produced by differences in salinity and temperature . Surface currents are formed by the friction of waves produced by the wind and by tides , the changes in local sea level produced by the gravity of the Moon and Sun . The direction of all of these is governed by surface and submarine land masses and by the rotation of the Earth ( the Coriolis effect ) . Former changes in sea levels have left continental shelves , shallow areas in the sea close to land . These nutrient-rich waters teem with life , which provide humans with substantial supplies of food -- mainly fish , but also shellfish , mammals , and seaweed -- which are both harvested in the wild and farmed . The most diverse areas surround great tropical coral reefs . Whaling in the deep sea was once common but whales ' dwindling numbers prompted international conservation efforts and finally a moratorium on most commercial hunting . Oceanography has established that not all life is restricted to the sunlit surface waters : even under enormous depths and pressures , nutrients streaming from hydrothermal vents support their own unique ecosystem . Life may have started there and aquatic microbial mats are generally credited with the oxygenation of Earth 's atmosphere ; both plants and animals first evolved in the sea . The sea is an essential aspect of human trade , travel , mineral extraction , and power generation . This has also made it essential to warfare and left major cities exposed to earthquakes and volcanoes from nearby faults ; powerful tsunami waves ; and hurricanes , typhoons , and cyclones produced in the tropics . This importance and duality has affected human culture , from early sea gods to the epic poetry of Homer to the changes induced by the Columbian Exchange , from burial at sea to Basho 's haikus to hyperrealist marine art , and inspiring music ranging from the shanties in The Complaynt of Scotland to Rimsky-Korsakov 's `` The Sea and Sinbad 's Ship '' to A-mei 's `` Listen to the Sea '' . It is the scene of leisure activities including swimming , diving , surfing , and sailing . However , population growth , industrialization , and intensive farming have all contributed to present-day marine pollution . Atmospheric carbon dioxide is being absorbed in increasing amounts , lowering its pH in a process known as ocean acidification .

Some ex-members and scholars have described the Sea Org as a totalitarian organization marked by intensive surveillance and a lack of freedom . In a 1992 memorandum by the Church of Scientology International , the following information was provided to the Internal Revenue Service with regards to nature of the Sea Org : -LSB- the Sea Org -RSB- does not have an ecclesiastical organizing board or command channels chart or secular existence such as an incorporated or unincorporated association . -LSB- ... -RSB- Although there is no such `` organization '' as the Sea Organization , the term Sea Org has a colloquial usage which implies that there is . There are general recruitment posters and literature for `` The Sea Org '' which implies that people will be employed by the Sea Org when in reality they will join , making the billion year commitment , at some church that is staffed by Sea Org members and become employees of that church corporation . -LSB- ... -RSB- The Sea Org exists as a spiritual commitment that is factually beyond the full understanding of the Service or any other but a trained and audited Scientologist . The Sea Org was established on August 12 , 1967 by L. Ron Hubbard , the founder of Dianetics and Scientology , initially on board four ships , the Diana , the Athena , the Apollo , and the Excalibur . The Apollo served as the flag ship of the Sea Org . In 1971 , the Sea Org assumed responsibility for the ecclesiastical development of the church , and in particular the delivery of the upper levels of its auditing and training , known as the Operating Thetan or `` OT '' levels . In 1981 , under the aegis of the Commodore 's Messenger Organization led by David Miscavige , the Sea Org dissolved the Guardian 's Office ( GO ) and assumed full responsibility for the international management of the Church , later reassigning the duties of the GO to the Office of Special Affairs in 1983 during the corporate restructuring of the Church . It moved to land-based organizations in 1975 , though maritime customs persist , with many members wearing naval-style uniforms and addressing both male and female officers as `` sir . '' In 1985 , the church purchased a 440 ft motor vessel , the Freewinds , which docks in Curaçao in the southern Caribbean and is used as a religious retreat and training center , staffed entirely by Sea Org members . Sea Org members make a lifetime commitment to Scientology by signing a billion-year contract that is officially described as a symbolic pledge . In exchange , members are given free room and board , and a small weekly allowance . Sea Org members agree to strict codes of discipline , such as disavowing premarital sex , working long hours ( on average at least 100 hours per week ) and living in communal housing , referred to as `` berthings '' .

Mars has no oceans and so no sea level , but at least two martian datums have been used to locate places there . Datums are used in geodesy , navigation , and surveying by cartographers and satellite navigation systems to translate positions indicated on maps ( paper or digital ) to their real position on Earth . Each starts with an ellipsoid ( stretched sphere ) , and then defines latitude , longitude and altitude coordinates . One or more locations on the Earth 's surface are chosen as anchor `` base-points '' . The difference in co-ordinates between datums is commonly referred to as datum shift .

Local factors might include tectonic effects , subsidence of the land , tides , currents , storms , etc. . Sea level rise is expected to continue for centuries .

Despite the short length , the canyon presented a formidable obstacle for the railroad , and the building of the line through it was considered a monumental engineering achievement in its day . Although the canyon is not directly accessible by roads , it is possible to view part of the canyon from the Grand County road ( CR 1 , or Trough Road ) that passes along its southern rim , as part of the Colorado Headwaters Scenic Byway . The California Zephyr also travels through the canyon .

Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1000 - in height . They are defined by oceanographers as independent features that rise to at least 1000 m above the seafloor , characteristically of conical form . The peaks are often found hundreds to thousands of meters below the surface , and are therefore considered to be within the deep sea . During their evolution over geologic time , the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface . After they have subsided and sunk below the sea surface such flat-top seamounts are called `` guyots '' or `` tablemounts '' A total of 9,951 seamounts and 283 guyots , covering a total of 8,796,150 km2 have been mapped but only a few have been studied in detail by scientists . Seamounts and guyots are most abundant in the North Pacific Ocean , and follow a distinctive evolutionary pattern of eruption , build-up , subsidence and erosion . In recent years , several active seamounts have been observed , for example Loihi in the Hawaiian Islands . Because of their abundance , seamounts are one of the most common marine ecosystems in the world . Interactions between seamounts and underwater currents , as well as their elevated position in the water , attract plankton , corals , fish , and marine mammals alike . Their aggregational effect has been noted by the commercial fishing industry , and many seamounts support extensive fisheries . There are ongoing concerns on the negative impact of fishing on seamount ecosystems , and well-documented cases of stock decline , for example with the orange roughy ( Hoplostethus atlanticus ) . 95 % of ecological damage is done by bottom trawling , which scrapes whole ecosystems off seamounts . Because of their large numbers , many seamounts remain to be properly studied , and even mapped . Bathymetry and satellite altimetry are two technologies working to close the gap . There have been instances where naval vessels have collided with uncharted seamounts ; for example , Muirfield Seamount is named after the ship that struck it in 1973 .

For instance as oceans are warming and becoming more acidic, biodiversity is becoming reduced and changing currents will cause more frequent storms and droughts. Every year around 8 million metric tons of plastic waste leak into the ocean and make it into the circular ocean currents. This causes contamination of sediments at the sea-bottom and causes plastic waste to be embedded in the aquatic food chain. It could lead to oceans containing more plastics than fish by 2050 if nothing is done. Key habitats such as coral reefs are at risk and noise pollution are a threat to whales, dolphins, and other species. Furthermore almost 90 percent of fish stocks are overfished or fully exploited which cost more than $80 billion a year in lost revenues.UN Secretary-General António Guterres stated that decisive, coordinated global action can solve the problems created by Humanity. Peter Thomson, President of the UN General Assembly, highlighted the conference's significance, saying \"if we want a secure future for our species on this planet, we have to act now on the health of the ocean and on climate change\".The conference sought to find ways and urge for the implementation of Sustainable Development Goal 14.

Ruddiman is a palaeoclimatologist and Professor Emeritus at the University of Virginia .

Ruddiman worked at the US Naval Oceanographic Office from 1969 to 1976 , and at Columbia 's Lamont -- Doherty Earth Observatory from 1976 to 1991 . He has a son named Dustin . He moved to Virginia in 1991 , serving as a Professor in Environmental Sciences . Ruddiman 's research interests center on climate change over several time scales . He is a Fellow of both the Geological Society of America and the American Geophysical Union . Ruddiman has participated in 15 oceanographic cruises , and was co-chief of two deep-sea drilling cruises . Ruddiman is best known for his `` early anthropocene '' hypothesis , the idea that human-induced changes in greenhouse gases did not begin in the eighteenth century with advent of coal-burning factories and power plants of the industrial era but date back to 8,000 years ago , triggered by the intense farming activities of our early agrarian ancestors . It was at that time that atmospheric greenhouse gas concentrations stopped following the periodic pattern of rises and falls that had accurately characterized their past long-term behavior , a pattern which is well explained by natural variations in the Earth 's orbit known as Milankovitch cycles . In his overdue-glaciation hypothesis Ruddiman claims that an incipient ice age would probably have begun several thousand years ago , but the arrival of that scheduled ice age was forestalled by the activities of early farmers . The overdue-glaciation hypothesis has been challenged on the grounds that alternative explanations are sufficient to account for the current warm anomaly without recourse to human activity , but Ruddiman challenges the methodology of his critics ( see external links ) . Ruddiman is also known for his hypothesis in the 1980s that the tectonic uplift of Tibet created the highly seasonal monsoonal circulation that dominates Asia today . With his then graduate student Maureen Raymo he hypothesised that the uplift of the Himalayas and Tibetan Plateau caused a reduction in atmospheric through increases in chemical weathering and was therefore a major causal factor in the Cenozoic Cooling trend that eventually led to our most recent series of Ice Ages . He was awarded the Lyell Medal of the Geological Society of London for 2010 . He has written several books : `` Plows , Plagues , and Petroleum : How Humans Took Control of Climate '' , a textbook on climate science , Earth 's Climate , Past and Future , and most recently Earth Transformed , the subject of the 2014 American Geophysical Union 's Tyndall Lecture .

Before joining the faculty at the University of Virginia , Thomson was a senior air pollution analyst and manager at the United States Environmental Protection Agency in both San Francisco and Washington D.C. . At EPA , Thomson advised top political appointees on Clean Air polities , conducted briefings , crafted legislative language , analyzed congressional proposals , reviewed state plans , developed regulations , and represented the Assistant Administrator on RCRA , SDWA , CWA , and FIFRA actions . From 2005 to 2006 , she was a Guest Scholar at the Pew Center of Global Climate Change . She has also been a consultant on energy and environmental issues . Appointed by Governor Mark Warner in 2002 , Thomson served as Vice Chair and member of the State Air Pollution Control Board , a seven-member regulatory body that makes air pollution policy and approves regulations for Virginia . She was reappointed by Governor Tim Kaine and served on the Board until 2010 . At UVA Thomson teaches environmental policy and seminar classes , including a survey course that introduces 150 undergraduates to a broad range of domestic and international environmental issues . In 2001 , Thomson co-founded the Environmental Thought and Practice Program , a selective interdisciplinary Bachelor of Arts degree program with 25 to 30 undergraduate majors .

Reed Writing Competition . The book explores the growing phenomenon of long-distance trash transport and related trash management issues and compares waste generation and consumption patterns in the U.S. with those in the European Union and Japan . Thomson 's most recent book is Sophisticated Interdependence in Climate Policy : Federalism in the United States , Brazil , and Germany ( Anthem Press , 2014 ) . Thomson proposes an innovative climate policy framework called `` sophisticated interdependence . This model is based on her lucid analysis of economic and political forces affecting climate change policy in selected US states , as well as on comparative descriptions of programs in Germany and Brazil , two powerful federal democracies whose policies are critical in the global climate change arena.Thomson has also written articles and extended reports on : law , politics , botany , air pollution , atmospheric science , and ethics . Thomson 's third book , forthcoming in April 2017 ( MIT Press ) , is -LSB- https://mitpress.mit.edu/books/climate-capitulation Climate of Capitulation : An Insider 's Account of State Power in a Coal Nation '' . Strong state-level political will and institutional capacity , especially in the forty states that produce or consume coal , are critical to the US 's success in reducing carbon dioxide emissions from electricity generation . However , entrenched state-level cultural , institutional , and economic forces threaten the viability of those efforts . This first-person decision-maker 's account shows how power is wielded at the state level in air pollution policymaking and reveals a `` climate of capitulation , '' that is , a deeply rooted tendency by politicians and high-level civil servants to capitulate to electric utility and coal interests . Thomson is a graduate of Princeton University , where she received her BA in Biology .

Pilkey ( born September 19 , 1934 ) is Professor Emeritus of Earth and Ocean Sciences , Nicholas School of the Environment , at Duke University , and Founder and Director Emeritus of the Program for the Study of Developed Shorelines ( PSDS ) which is currently based at Western Carolina University . Pilkey received his B.S. degree in geology at Washington State College , his M.S. degree in geology at the University of Montana and his Ph.D. degree in geology at Florida State University . Between 1962 and 1965 , he was a research professor at the University of Georgia Marine Institute on Sapelo Island . He has been at Duke University since 1965 , with one year breaks with the Department of Marine Science at the University of Puerto Rico , Mayagüez , and with the U.S. Geological Survey in Woods Hole , Massachusetts . Pilkey began his career with the study of abyssal plains on the deep sea floor . As a result of the destruction of his parents ' house in Waveland , Mississippi in Hurricane Camille ( 1969 ) , he switched to the study of coasts . Pilkey 's research centers on both basic and applied coastal geology , focusing primarily on barrier island coasts and the effects of shoreline stabilization and development , and sea-level rise . The PSDS has analyzed the numerical models used by coastal geologists and engineers to predict the movement of beach sand , especially in beach replenishment . In general , Pilkey argues that mathematical models can not be used to accurately predict the behavior of beaches , although they can be useful if directional or orders-of-magnitude answers are sought . In the book , Useless Arithmetic , written with his daughter , Linda Pilkey-Jarvis , they argue that the outcome of natural processes in general can not be accurately predicted by mathematical models.The Rising Sea , written with Rob Young , current director of PSDS , focuses on the global threat from sea level rise . The Last Beach sounds the alarm that recreation on many of the world 's beaches is going to be a thing of the past . It explains that `` the future of the world 's beaches hangs in the balance , from big threats such as engineering , mining , and pollution , to activities that seem harmless , like driving on beaches . '' In many places , pollution is in the beach sand as well as in the water . Retreat from a Rising Sea , written with daughter , Linda , and son , Keith , highlights the need for moving back from the coast , a process that is already beginning in some parts of the world , such as Arctic barrier islands , atolls , and river deltas . The authors think that New Orleans and Miami , among other cities , are doomed . His most recent book , Lessons from the Sand , offers easy experiments for kids ( and adults ) to do while learning about beach processes . Orrin co-wrote this colorful book which is completely illustrated by his son and co-author , Charles Pilkey , an artist/sculptor . Pilkey has received numerous awards , among them the Francis Parker Shepard medal for excellence in marine geology in 1987 , and in 2003 , the Priestly Award , for distinguished research in coastal geology and public service in policy formulation and education about America 's coastal resources , presented by Dickinson College , Pennsylvania . In 2012 , Duke University honored Pilkey by naming a new research building for him at the Duke Marine Lab , Beaufort , North Carolina .

As approximately 97 % of publishing climate scientists support the consensus on anthropogenic climate change , this list represents a minority viewpoint . The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise . The balance of impacts of global warming become significantly negative at larger values of warming . These findings are recognized by the national science academies of all the major industrialized nations ; the consensus has strengthened over time and is now virtually unanimous . The level of consensus correlates with expertise in climate science . There have been several efforts to compile lists of dissenting scientists , including a 2008 US senate minority report , the Oregon Petition , and a 2007 list by the Heartland Institute , all three of which have been criticized on a number of grounds . For the purpose of this list , a `` scientist '' is defined as an individual who has published at least one peer-reviewed research article in the broad field of natural sciences , although not necessarily in a field relevant to climatology . Since the publication of the IPCC Third Assessment Report , each has made a clear statement in his or her own words ( as opposed to the name being found on a petition , etc. ) disagreeing with one or more of the report 's three main conclusions . Their views on climate change are usually described in more detail in their biographical articles . Few of the statements in the references for this list are part of the peer-reviewed scientific literature ; most are from other sources such as interviews , opinion pieces , online essays and presentations .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' . There are significant regional differences , with Americans and Chinese ( whose economies are responsible for the greatest annual CO2 emissions ) among the least concerned .", "qid": "642", "docid": "Global_warming", "rank": 2, "score": 150045 }, { "content": "Title: Future sea level Content: The rate of global mean sea-level rise ( ~ 3 mm/yr ; SLR ) has accelerated compared to the mean of the 20th century ( ~ 2 mm/yr ) , but the rate of rise is locally variable .

On Antarctica the deficiency increased by 75 % .

The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases , especially carbon dioxide . When the global temperature changes , the changes in climate are not expected to be uniform across the Earth . In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores . Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years . There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere .

This climate event began at the time boundary between the Paleocene and Eocene geological epochs . The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago . The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years . The entire warm period lasted for about 200,000 years . Global temperatures increased by 5 -- 8 ° C . The carbon dioxide was likely released in two pulses , the first lasting less than 2,000 years . Such a repeated carbon release is in line with current global warming . A main difference is that during the Paleocene -- Eocene Thermal Maximum , the planet was essentially ice-free . The onset of the Paleocene -- Eocene Thermal Maximum has been linked to an initial 5 ° C temperature rise and to extreme changes in Earth 's carbon cycle . The period is marked by a prominent negative excursion in carbon stable isotope records from around the globe ; more specifically , there was a large decrease in 13C/12C ratio of marine and terrestrial carbonates and organic carbon . Stratigraphic sections of rock from this period reveal numerous other changes . Fossil records for many organisms show major turnovers . For example , in the marine realm , a mass extinction of benthic foraminifera , a global expansion of subtropical dinoflagellates , and an appearance of excursion , planktic foraminifera and calcareous nanofossils all occurred during the beginning stages of PETM . On land , modern mammal orders ( including primates ) suddenly appear in Europe and in North America . Sediment deposition changed significantly at many outcrops and in many drill cores spanning this time interval . At least since 1997 , the Paleocene -- Eocene Thermal Maximum has become a focal point of considerable geoscience research because it probably provides the best past analog by which to understand impacts of global climate warming and of massive carbon input to the ocean and atmosphere , including ocean acidification .

The degree Celsius ( ° C ) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval , a difference between two temperatures or an uncertainty . Before being renamed to honour Anders Celsius in 1948 , the unit was called centigrade , from the Latin centum , which means 100 , and gradus , which means steps . The current scale is based on 0 ° for the freezing point of water and 100 ° for the boiling point of water at 1 atm pressure following a change introduced by Jean-Pierre Christin to reverse the Celsius thermometer scale ( from water boiling at 0 degrees and ice melting at 100 degrees ) . This scale is widely taught in schools today . By international agreement the unit `` degree Celsius '' and the Celsius scale are currently defined by two different temperatures : absolute zero , and the triple point of Vienna Standard Mean Ocean Water ( VSMOW ) , a specially purified water . This definition also precisely relates the Celsius scale to the Kelvin scale , which defines the SI base unit of thermodynamic temperature with symbol K.

Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional : the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that `` Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely '' the highest in at least the past 1,300 years .

Individual proxy records , such as tree ring widths and densities used in dendroclimatology , are calibrated against the instrumental record for the period of overlap .

In the current episode of global warming many such 15-year periods appear in the surface temperature record , along with robust evidence of the long-term warming trend ; climate is classically averaged over 30-year periods . Publicity has surrounded claims of a global warming hiatus during the period 1998 -- 2013 . The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend , and so subsequent annual temperatures gave the appearance of a hiatus : by January 2006 , it appeared to some that global warming had stopped or paused . A 2009 study showed that decades without warming were not exceptional , and in 2011 a study showed that if allowances were made for known variability , the rising temperature trend continued unabated . There was increased public interest in 2013 in the run-up to publication of the IPCC Fifth Assessment Report , and despite concerns that a 15-year period was too short to determine a meaningful trend , the IPCC included a section on a hiatus , which it defined as a much smaller increasing linear trend over the 15 years from 1998 to 2012 , than over the 60 years from 1951 to 2012 . Various studies examined possible causes of the short-term slowdown . Even though the overall climate system has continued to accumulate energy due to Earth 's positive energy budget , the available temperature readings at the Earth 's surface indicate slower rates of increase in surface warming than in the prior decade . Since measurements at the top of the atmosphere show that Earth is receiving more energy than it is radiating back into space , the retained energy should be producing warming in the Earth 's climate system . Research reported in July 2015 on an updated NOAA dataset casts doubt on the existence of a hiatus , and it finds no indication of a slowdown even in earlier years . Scientists working on other datasets welcomed this study , though they have expressed the view that the recent warming trend was less than in previous periods of the same length . Subsequently , a detailed study supports the conclusion that warming is continuing , but it also find there was less warming between 2001 and 2010 than climate models had predicted , and that this slowdown might be attributed to short-term variations in the Pacific decadal oscillation ( PDO ) , which was negative during that period . Another review finds `` no substantive evidence '' of a pause in global warming . A statistical study of global temperature data since 1970 concludes that the term ` hiatus ' or ` pause ' is not justified . Independent of these discussions about data and measurements for earlier years , 2015 turned out to be much warmer than any of the earlier years , already before El Niño conditions started . The warmth of 2015 largely ended any remaining scientific credibility of claims that the supposed `` hiatus '' since 1998 had any significance for the long-term warming trend . In January 2017 , a study published in the journal Science Advances cast further doubt on the existence of a recent pause , with more evidence that ocean temperatures have been underestimated . An April 2017 study found the data consistent with a steady warming trend globally since the 1970s , with fluctuations within the expected range of short term variability .", "qid": "642", "docid": "Global_warming_hiatus", "rank": 32, "score": 102572 }, { "content": "Title: Atmospheric methane Content: Atmospheric methane is the methane present in Earth 's atmosphere .

These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century , with the instrumental temperature record by 2000 exceeding earlier temperatures . The term `` hockey stick graph '' was coined by the climatologist Jerry Mahlman , to describe the pattern shown by the ( MBH99 ) reconstruction , envisaging a graph that is relatively flat with a downward trend to 1900 as forming an ice hockey stick 's `` shaft '' followed by a sharp , steady increase corresponding to the `` blade '' portion . The reconstructions have featured in Intergovernmental Panel on Climate Change ( IPCC ) reports as evidence of global warming . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . Paleoclimatology dates back to the 19th century , and the concept of examining varves in lake beds and tree rings to track local climatic changes was suggested in the 1930s . In the 1960s , Hubert Lamb generalised from historical documents and temperature records of central England to propose a Medieval Warm Period from around 900 to 1300 , followed by Little Ice Age . This was the basis of a `` schematic diagram '' featured in the IPCC First Assessment Report of 1990 beside cautions that the medieval warming might not have been global . The use of indicators to get quantitative estimates of the temperature record of past centuries was developed , and by the late 1990s a number of competing teams of climatologists found indications that recent warming was exceptional . introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large scale reconstructions . Their study was featured in the IPCC Second Assessment Report of 1995 . In 1998 Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 with shading emphasising that uncertainties ( to two standard error limits ) were much greater in earlier centuries . independently produced a CPS reconstruction extending back for a thousand years , and ( MBH99 ) used the MBH98 methodology to extend their study back to 1000 . A version of the MBH99 graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , which also drew on Jones et al. 1998 and three other reconstructions to support the conclusion that , in the Northern Hemisphere , the 1990s was likely to have been the warmest decade and 1998 the warmest year during the past 1,000 years . The graph became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th century warmth was exceptional . In 2003 , as lobbying over the 1997 Kyoto Protocol intensified , a paper claiming greater medieval warmth was quickly dismissed by scientists in the Soon and Baliunas controversy . Later in 2003 , Stephen McIntyre and Ross McKitrick published disputing the data used in MBH98 paper . In 2004 Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small .

The first phase of the global heatwaves was caused by a moderate El Niño event, which lasted from June 2009 to May 2010. The first phase lasted only from April 2010 to June 2010, and caused only moderate above average temperatures in the areas affected. But it also set new record high temperatures for most of the area affected, in the Northern Hemisphere. The second phase (the main, and most devastating phase) was caused by a very strong La Niña event, which lasted from June 2010 to June 2011. According to meteorologists, the 2010–11 La Niña event was one of the strongest La Niña events ever observed. That same La Niña event also had devastating effects in the Eastern states of Australia. The second phase lasted from June 2010 to October 2010, caused severe heat waves, and multiple record-breaking temperatures. The heatwaves began on April 2010, when strong anticyclones began to develop, over most of the affected regions, in the Northern Hemisphere. The heatwaves ended in October 2010, when the powerful anticyclones over most of the affected areas dissipated. The heat wave during the summer of 2010 was at its worst in June, over the Eastern United States, Middle East, Eastern Europe and European Russia, and over Northeastern China and southeastern Russia. June 2010 marked the fourth consecutive warmest month on record globally, at 0.66 °C (1.22 °F) above average, while the period April–June was the warmest ever recorded for land areas in the Northern Hemisphere, at 1.25 °C (2.25 °F) above average. The previous record for the global average temperature in June was set in 2005 at 0.66 °C (1.19 °F), and the previous warm record for April–June over Northern Hemisphere land areas was 1.16 °C (2.09 °F), set in 2007. The strongest of the anticyclones, the one situated over Siberia, registered a maximum high pressure of 1040 millibars. The weather caused forest fires in China, where three in a team of 300 died fighting a fire that broke out in the Binchuan County of Dali, as Yunnan suffered the worst drought in 60 years by February 17.

Between 1971 and 2014, during a period of global warming, Tuvalu islands have increased in size, according to aerial photography and satellite imagery. Over four decades, there was a net increase in land area in Tuvalu of 73.5 ha (2.9%), although the changes were not uniform, with 74% of land increasing in size and 27% of land decreasing in size. The sea level at the Funafuti tide gauge has risen at 3.9 mm per year, which is approximately twice the global average.Tuvalu could be one of the first nations to be significantly impacted by rising sea levels. Not only could parts of the island be flooded but the rising saltwater table could also destroy deep rooted food crops such as coconut, pulaka, and taro.

Reconstructions have consistently shown that the rise in the instrumental temperature record of the past 150 years is not matched in earlier centuries , and the name `` hockey stick graph '' was coined for figures showing a long-term decline followed by an abrupt rise in temperatures . These graphs were publicised to explain the scientific findings of climatology , and in addition to scientific debate over the reconstructions , they have been the topic of political dispute . The issue is part of the global warming controversy and has been one focus of political responses to reports by the Intergovernmental Panel on Climate Change ( IPCC ) . Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast doubt on climate science . The use of proxy indicators to get quantitative estimates of the temperature record of past centuries was developed from the 1990s onwards , and found indications that recent warming was exceptional . The reconstruction introduced the `` Composite Plus Scaling '' ( CPS ) method used by most later large-scale reconstructions , and its findings were disputed by Patrick Michaels at the United States House Committee on Science . In 1998 , Michael E. Mann , Raymond S. Bradley and Malcolm K. Hughes developed new statistical techniques to produce ( MBH98 ) , the first eigenvector-based climate field reconstruction ( CFR ) . This showed global patterns of annual surface temperature , and included a graph of average hemispheric temperatures back to 1400 . In ( MBH99 ) the methodology was extended back to 1000 . The term hockey stick was coined by the climatologist Jerry D. Mahlman , to describe the pattern this showed , envisaging a graph that is relatively flat to 1900 as forming an ice hockey stick 's `` shaft '' , followed by a sharp increase corresponding to the `` blade '' . A version of this graph was featured prominently in the 2001 IPCC Third Assessment Report ( TAR ) , along with four other reconstructions supporting the same conclusion . The graph was publicised , and became a focus of dispute for those opposed to the strengthening scientific consensus that late 20th-century warmth was exceptional . Those disputing the graph included Pat Michaels , the George C. Marshall Institute and Fred Singer . A paper by Willie Soon and Sallie Baliunas claiming greater medieval warmth was used by the Bush administration chief of staff Philip Cooney to justify altering the first Environmental Protection Agency Report on the Environment . The paper was quickly dismissed by scientists in the Soon and Baliunas controversy , but on July 28 , Republican Jim Inhofe spoke in the Senate citing it to claim `` that man-made global warming is the greatest hoax ever perpetrated on the American people '' . Later in 2003 , a paper by Steve McIntyre and Ross McKitrick disputing the data used in MBH98 paper was publicised by the George C. Marshall Institute and the Competitive Enterprise Institute . In 2004 , Hans von Storch published criticism of the statistical techniques as tending to underplay variations in earlier parts of the graph , though this was disputed and he later accepted that the effect was very small . In 2005 , McIntyre and McKitrick published criticisms of the principal component analysis methodology as used in MBH98 and MBH99 . The analysis therein was subsequently disputed by published papers , including and , which pointed to errors in the McIntyre and McKitrick methodology . In June 2005 , Rep. Joe Barton launched what Sherwood Boehlert , chairman of the House Science Committee , called a `` misguided and illegitimate investigation '' into the data , methods and personal information of Mann , Bradley and Hughes . At Boehlert 's request , a panel of scientists convened by the National Research Council was set up , which reported in 2006 , supporting Mann 's findings with some qualifications , including agreeing that there were some statistical failings but these had little effect on the result .

First , the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole , which in turn , holds in a frozen mass of Arctic air . Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans . Bell and Strieber explain the possibility that such current destabilizations have occurred before , as well as seemingly impossible engineering feats by the ancients . Among their examples is the island city of Nan Madol . The book claims that its construction , with exacting tolerances and extremely heavy basalt materials , necessitates a high degree of technical competency . Since no such society exists in the modern record or even , in legend , the society must have been destroyed by dramatic means . While other explanations beside a global meteorological event are possible , a correlating evidence set is presented in the woolly mammoth . Strieber and Bell assert that since mammoths have been found preserved with food still in their mouths and undigested in their stomachs , these animals must have been killed quickly , in otherwise normal conditions . They were preserved so well by quick freezing , which is taken as evidence of a rapid onset of a global blizzard or similar event . Interspersed with the analytical parts of the book are a series of interlinked short fictional scenarios , written in italics , describing what might transpire today if a destabilization of the North Atlantic Current were to occur . The fictional accounts of `` current events '' as the meteorological situation deteriorates provided background and inspiration for the 2004 science fiction film The Day After Tomorrow .

It may lead to phenomena such as houses feeling cooler in the winter and warmer in the summer at the same temperature . For example , in a room in which air temperature is maintained at 22 ° Celsius at all times , but in which the inner surfaces of the house is estimated to be an average temperature of 10 ° Celsius in the winter or 25 ° Celsius in the summer , heat transfer from the surfaces to the individual will occur , resulting in a difference in the perceived temperature . We can observe and compare the rate of radiation heat transfer between a person and the surrounding surfaces if we first make a few simplifying assumptions : The heat exchange in the environment is in a `` steady state '' , meaning that there is a constant flow of heat either into or out of the house . The person is completely surrounded by the interior surfaces of the room . Heat transfer by convection is not considered . The walls , ceiling , and floor are all at the same temperature . For an average person , the outer surface area is 1.4 m ² , the surface temperature is 30 ° Celsius , and the emissivity is 0.95 . Emissivity is the ability of a surface to emit radiant energy compared to that of a black body at the same temperature . We will be using the following equation to find out how much heat is lost by a person standing in the same room in summertime as compared to the winter , at exactly the same thermostat reading temperature : Q ̇ = εσA_s ( T_s ^ 4-T_surr ^ 4 ) Where Q ̇ is the rate of heat loss ( W ) , ε is the emissivity ( or the ability of an objects surface to emit energy by radiation ) of a person , σ is the Stefan-Boltzmann constant ( 5.670 x 10 ^ ( -8 ) W/m2 ∙ K4 ) , As is the surface area of a person , Ts is the surface temperature of a person ( K ) , and Tsurr is the surface temperature of the walls , ceiling , and floor ( K ) . Please note that this equation is only valid for an object standing in a completely enclosed room , box , etc. .

It differs from other forms of electromagnetic radiation such as x-rays , gamma rays , microwaves , radio waves , and television rays that are not related to temperature . Scientists have found that all bodies at a temperature above absolute zero emit thermal radiation . People are constantly radiating their body heat , but at different rates .

It appears to be the second major hyperthermal that punctuated the long-term warming trend from the Late Paleocene through the early Eocene ( 58 to 50 Ma ) . The hyperthermals were geologically brief time intervals ( < 200,000 years ) of global warming and massive carbon input . The most extreme and best-studied event , the Paleocene-Eocene Thermal Maximum ( PETM or ETM-1 ) , occurred about 1.8 million years before ETM-2 , at approximately 55.5 Ma . Other hyperthermals likely followed ETM-2 at nominally 53.6 Ma ( H-2 ) , 53.3 ( I-1 ) , 53.2 ( I-2 ) and 52.8 Ma ( informally called K , X or ETM-3 ) . The number , nomenclature , absolute ages and relative global impact of the Eocene hyperthermals are the source of much current research . In any case , the hyperthermals appear to have ushered in the Early Eocene Climatic Optimum , the warmest interval of the Cenozoic Era . They also definitely precede the Azolla event at about 49 Ma . ETM-2 is clearly recognized in sediment sequences by analyzing the stable carbon isotope composition of carbon-bearing material . The 13C/12C ratio of calcium carbonate or organic matter drops significantly across the event . This is similar to what happens when one examines sediment across the PETM , although the magnitude of the negative carbon isotope excursion is not as large . The timing of Earth system perturbations during ETM-2 and the PETM also appear different . Specifically , the onset of ETM-2 may have been longer ( perhaps 30,000 years ) while the recovery seems to have been shorter ( perhaps < 50,000 years ) . ( Note , however , that the timing of short-term carbon cycle perturbations during both events remains difficult to constrain ) . A thin clay-rich horizon marks ETM-2 in marine sediment from widely separated locations . In sections recovered from the deep-sea ( for example those recovered by Ocean Drilling Program Leg 208 on Walvis Ridge ) , this layer is caused by dissolution of calcium carbonate . However , in sections deposited along continental margins ( for example those now exposed along the Clarence River , New Zealand ) , the clay-rich horizon represents dilution by excess accumulation of terrestrial material entering into the ocean . Similar changes in sediment accumulation are found across the PETM . In sediment from Lomonosov Ridge in the Arctic Ocean , intervals across both ETM-2 and the PETM shows signs of higher temperature , lower salinity and lower dissolved oxygen . The PETM and ETM-2 are thought to have a similar generic origin , although this idea is at the edge of current research . During both events , a tremendous amount of 13C-depleted carbon rapidly entered the ocean and atmosphere . This decreased the 13C/12C ratio of carbon-bearing sedimentary components , and dissolved carbonate in the deep ocean . Somehow the carbon input was coupled to an increase in Earth surface temperature and a greater seasonality in precipitation , which explains the excess terrestrial sediment discharge along continental margins . Possible explanations for changes during ETM-2 are the same as those for the PETM , and are discussed under the latter entry . The H-2 event appears to be a `` minor '' hyperthermal that follows ETM-2 ( H-1 ) by about 100,000 years . This has led to speculation that the two events are somehow coupled and paced by changes in orbital eccentricity .

Circulation in the atmosphere and oceans is primarily driven by solar radiation and transports heat from the tropical regions to regions that receive less energy from the Sun. The water cycle also moves energy throughout the climate system. In addition, different chemical elements, necessary for life, are constantly recycled between the different components. The climate system can change due to internal variability and external forcings. These external forcings can be natural, such as variations in solar intensity and volcanic eruptions, or caused by humans. Accumulation of heat-trapping greenhouse gases, mainly being emitted by people burning fossil fuels, is causing global warming.

Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically .

The altitude of the mesopause for many years was assumed to be at around 85 km ( 53 mi . ) , but observations to higher altitudes and modeling studies in the last 10 years have shown that in fact the mesopause consists of two minima - one at about 85 km and a stronger minimum at about 100 km .

Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause . In the mesosphere the summer-to-winter circulation is due to gravity wave dissipation , which deposits momentum against the mean east-west flow , resulting in a small north-south circulation . In recent years the mesopause has also been the focus of studies on global climate change associated with increases in CO2 . Unlike the troposphere , where greenhouse gases result in the atmosphere heating up , increased CO2 in the mesosphere acts to cool the atmosphere due to increased radiative emission .

The project works to study what species live in coral reef ecosystems , to develop standardized protocols for studying coral reef ecosystems , and to increase access to and exchange of information about coral reefs scattered throughout the globe . The CReefs project uses the implementation of autonomous reef-monitoring structures ( ARMS ) to study the species that inhabit coral reefs . These structures are placed on the sea floor in areas where coral reefs exist , where they are left for one year . At the end of the year , the ARMS is pulled to the surface , along with the species which have inhabited it , for analysis . Coral reefs are thought to be the most organically different of all marine ecosystems . Major declines in key reef ecosystems suggest a decline in reef population throughout the world due to environmental stresses . The vulnerability of coral reef ecosystems is expected to increase significantly in response to climate change . The reefs are also being threatened by induced coral bleaching , ocean acidification , sea-level rise , and changing storm tracks . Reef biodiversity could be in danger of being lost before it is even documented , and researchers will be left with a limited and poor understanding of these complex ecosystems . In an attempt to enhance global understanding of reef biodiversity , the goals of the CReefs Census of Coral Reef Ecosystems were to conduct a diverse global census of coral reef ecosystems . And increase access to and exchange of coral reef data throughout the world . Because coral reefs are the most diverse and among the most threatened of all marine ecosystems , there is great justification to learn more about them .", "qid": "644", "docid": "Census_of_Coral_Reefs", "rank": 11, "score": 103327 }, { "content": "Title: Environmental issues with coral reefs Content: Human impact on coral reefs is significant . Coral reefs are dying around the world . In particular , coral mining , pollution ( organic and non-organic ) , overfishing , blast fishing and the digging of canals and access into islands and bays are serious threats to these ecosystems . Coral reefs also face high dangers such as diseases , destructive fishing practices and warming oceans . In order to find answers for these problems , researchers study the various factors that impact reefs . The list of factors is long , including the ocean 's role as a carbon dioxide sink , atmospheric changes , ultraviolet light , ocean acidification , viruses , impacts of dust storms carrying agents to far-flung reefs , pollutants , algal blooms and others . Reefs are threatened well beyond coastal areas . In 2008 estimates assembled from coral reef specialists from around the world indicated that 19 % of the existing area of coral reefs has already been lost , and that a further 17 % is likely to be lost over the subsequent 10 -- 20 years . Only 46 % of the world 's reefs could be currently regarded as in good health . About 60 % of the world 's reefs may be at risk due to destructive , human-related activities . The threat to the health of reefs is particularly strong in Southeast Asia , where 80 % of reefs are endangered . By the 2030s , 90 % of reefs are expected to be at risk from both human activities and climate change ; by 2050 , all coral reefs will be in danger . Coral Reef loss has been cause for concern for a long time , but is now starting to gain traction as one of the worlds greatest environmental threats . The current greatest threat to the reefs are coral bleaching , which is the loss of the endosymbiotic algae from the coral ( the thing that gives coral it 's vibrant color ) due to rising ocean water temperatures . Some other threats that are not as prominent but still play a factor to the loss of the world 's reefs are poisonous fishing practices , explosive fishing practices , careless tourism , and pollution . The loss of the coral reefs will come with consequences such as human vulnerability , environmental chaos , and a massive , relatively unseen , economic cost .", "qid": "644", "docid": "Environmental_issues_with_coral_reefs", "rank": 12, "score": 102689 }, { "content": "Title: Goniastrea stelligera Content: Goniastrea stelligera , commonly known as knob coral , is a species of stony coral in the family Merulinidae .

For instance as oceans are warming and becoming more acidic, biodiversity is becoming reduced and changing currents will cause more frequent storms and droughts. Every year around 8 million metric tons of plastic waste leak into the ocean and make it into the circular ocean currents. This causes contamination of sediments at the sea-bottom and causes plastic waste to be embedded in the aquatic food chain. It could lead to oceans containing more plastics than fish by 2050 if nothing is done. Key habitats such as coral reefs are at risk and noise pollution are a threat to whales, dolphins, and other species. Furthermore almost 90 percent of fish stocks are overfished or fully exploited which cost more than $80 billion a year in lost revenues.UN Secretary-General António Guterres stated that decisive, coordinated global action can solve the problems created by Humanity. Peter Thomson, President of the UN General Assembly, highlighted the conference's significance, saying \"if we want a secure future for our species on this planet, we have to act now on the health of the ocean and on climate change\".The conference sought to find ways and urge for the implementation of Sustainable Development Goal 14.

If a planet 's atmosphere contains radiatively active gases ( i.e. , greenhouse gases ) the atmosphere will radiate energy in all directions . Part of this radiation is directed towards the surface , warming it . The downward component of this radiation -- that is , the strength of the greenhouse effect -- will depend on the atmosphere 's temperature and on the amount of greenhouse gases that the atmosphere contains . On Earth , the atmosphere is warmed by absorption of infrared thermal radiation from the underlying surface ( heated by the sun ) , absorption of shorter wavelength radiant energy from the sun , and convective heat fluxes from the surface . Greenhouse gases in the atmosphere radiate energy , some of which is directed to the surface and lower atmosphere .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases , especially carbon dioxide . When the global temperature changes , the changes in climate are not expected to be uniform across the Earth . In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores . Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years . There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere .

A GWP is calculated over a specific time interval , commonly 20 , 100 , or 500 years . GWP is expressed as a factor of carbon dioxide ( whose GWP is standardized to 1 ) .

User related choices such as the time horizon can greatly affect the numerical values obtained for carbon dioxide equivalents . For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph .

Political and popular debate concerning the existence and cause of climate change includes the reasons for the increase seen in the instrumental temperature record , whether the warming trend exceeds normal climatic variations , and whether human activities have contributed significantly to it . Scientists have resolved these questions decisively in favour of the view that the current warming trend exists and is ongoing , that human activity is the cause , and that it is without precedent in at least 2000 years . Public disputes that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases ( climate sensitivity ) , how global climate change will play out at local and regional scales , and what the consequences of global warming will be . Global warming remains an issue of widespread political debate , often split along party political lines , especially in the United States . Many of the issues that are settled within the scientific community , such as human responsibility for global warming , remain the subject of politically or economically motivated attempts to downplay , dismiss or deny them -- an ideological phenomenon categorised by academics and scientists as climate change denial . The sources of funding for those involved with climate science -- both supporting and opposing mainstream scientific positions -- have been questioned by both sides . There are debates about the best policy responses to the science , their cost-effectiveness and their urgency . Climate scientists , especially in the United States , have reported official and oil-industry pressure to censor or suppress their work and hide scientific data , with directives not to discuss the subject in public communications . Legal cases regarding global warming , its effects , and measures to reduce it have reached American courts . The fossil fuels lobby has been identified as overtly or covertly supporting efforts to undermine or discredit the scientific consensus on global warming .", "qid": "644", "docid": "Global_warming_controversy", "rank": 70, "score": 76840 }, { "content": "Title: Thermal runaway Content: Thermal runaway occurs in situations where an increase in temperature changes the conditions in a way that causes a further increase in temperature , often leading to a destructive result . It is a kind of uncontrolled positive feedback . In other words , `` thermal runaway '' describes a process which is accelerated by increased temperature , in turn releasing energy that further increases temperature .

In electrical engineering , thermal runaway is typically associated with increased current flow and power dissipation , although exothermic chemical reactions can be of concern here too . Thermal runaway can occur in civil engineering , notably when the heat released by large amounts of curing concrete is not controlled -LCB- Citation needed -RCB- . In astrophysics , runaway nuclear fusion reactions in stars can lead to nova and several types of supernova explosions , and also occur as a less dramatic event in the normal evolution of solar mass stars , the `` helium flash '' . There are also concerns regarding global warming that a global average increase of 3 -- 4 degrees Celsius above the preindustrial baseline could lead to a further unchecked increase in surface temperatures .

The part of a molecule responsible for its color is called chromophore . Light encountering a painted surface can either alter or break the chemical bonds of the pigment , resulting the colors to bleach or change , in a process known as photodegradation . Materials that resist this effect are said to be lightfast . The electromagnetic spectrum of the sun contains wavelengths from gamma waves to radio waves . The high energy of ultraviolet radiation in particular accelerates the fading of the dye . The photon energy of UVA-radiation which is not absorbed by atmospheric ozone exceeds the dissociation energy of the carbon-carbon single bond , resulting in the cleavage of the bond and fading of the color . Inorganic colourants are considered to be more lightfast than organic colourants . Black colourants are usually considered the most lightfast .

The major heating source of Earth and its moon is radioactive heating , but the heating source on Io is tidal heating . As Jupiter is very massive , the side of Io nearest to Jupiter has a slightly larger gravitational pull than the opposite side . This difference in gravitational forces cause distortion of Io 's shape . Differently from the Earth 's only moon , Jupiter has several moons ( i.e. Io , Europa , Ganymede and Callisto ) . As Io is the innermost moon of Jupiter , Jupiter pulls Io inward and other moons pull Io outward . This causes Io 's orbit to be elliptical and eccentric . The distance between Jupiter and Io changes all the time and the distortion of Io likewise changes all the time . The constant change in the shape of Io results in a large amount of friction in the moon and the friction-induced heating drives strong volcanic activities on the surface of Io .

Scientists just discovered a massive, heretofore unknown, source of nitrogen
[ { "content": "Title: Nitrogen Content: Nitrogen is a chemical element with symbol N and atomic number 7 . It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 . Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time , Rutherford is generally accorded the credit because his work was published first . The name nitrogen was suggested by Jean-Antoine-Claude Chaptal in 1790 , when it was found that nitrogen was present in nitric acid and nitrates ; this name derives from the Greek roots νἰτρον `` nitre '' and - γεννᾶν `` to form '' . Antoine Lavoisier suggested instead the name azote , from the Greek άζωτικός `` no life '' , as it is an asphyxiant gas ; his name is instead used in many languages , such as French , Russian , and Turkish , and appears in the English names of some nitrogen compounds such as hydrazine , azides and azo compounds . Nitrogen is the lightest member of group 15 of the periodic table , often called the pnictogens . The name comes from the Greek πνίγειν `` to choke '' , directly referencing nitrogen 's asphyxiating properties . It is a common element in the universe , estimated at about seventh in total abundance in the Milky Way and the Solar System . At standard temperature and pressure , two atoms of the element bind to form dinitrogen , a colourless and odorless diatomic gas with the formula N2 . Dinitrogen forms about 78 % of Earth 's atmosphere , making it the most abundant uncombined element . Nitrogen occurs in all organisms , primarily in amino acids ( and thus proteins ) , in the nucleic acids ( DNA and RNA ) and in the energy transfer molecule adenosine triphosphate . The human body contains about 3 % nitrogen by mass , the fourth most abundant element in the body after oxygen , carbon , and hydrogen . The nitrogen cycle describes movement of the element from the air , into the biosphere and organic compounds , then back into the atmosphere . Many industrially important compounds , such as ammonia , nitric acid , organic nitrates ( propellants and explosives ) , and cyanides , contain nitrogen . The extremely strong triple bond in elemental nitrogen ( N ≡ N ) , the second strongest bond in any diatomic molecule , dominates nitrogen chemistry . This causes difficulty for both organisms and industry in converting N2 into useful compounds , but at the same time means that burning , exploding , or decomposing nitrogen compounds to form nitrogen gas releases large amounts of often useful energy . Synthetically produced ammonia and nitrates are key industrial fertilisers , and fertiliser nitrates are key pollutants in the eutrophication of water systems . Apart from its use in fertilisers and energy-stores , nitrogen is a constituent of organic compounds as diverse as Kevlar used in high-strength fabric and cyanoacrylate used in superglue .

A large nitrogen abundance has been measured on the surface of the stars , about six times the abundance of nitrogen measured in the sun . This nitrogen is probably produced in deeper layers of the star and pushed towards the surface by rotational mixing .

He rationalized that if he dissolved dry materials in water they would be better utilized by the plant . This led to the inception of liquid fertilizers .

Nitrogen was first liquefied at the Jagiellonian University on 15 April 1883 by Polish physicists , Zygmunt Wróblewski and Karol Olszewski . It is produced industrially by fractional distillation of liquid air . Liquid nitrogen is often referred to by the abbreviation , LN2 or `` LIN '' or `` LN '' and has the UN number 1977 . Liquid nitrogen is a diatomic liquid , which means that the diatomic character of the covalent N bonding in N2 gas is retained after liquefaction . Liquid nitrogen is a cryogenic fluid that can cause rapid freezing on contact with living tissue . When appropriately insulated from ambient heat , liquid nitrogen can be stored and transported , for example in vacuum flasks . The temperature is held constant at 77 K by slow boiling of the liquid , resulting in the evolution of nitrogen gas . Depending on the size and design , the holding time of vacuum flasks ( Dewars ) ranges from a few hours to a few weeks . The development of pressurised super-insulated vacuum vessels has enabled liquefied nitrogen to be stored and transported over longer time periods with losses reduced to 2 % per day or less . The temperature of liquid nitrogen can readily be reduced to its freezing point 63 K by placing it in a vacuum chamber pumped by a vacuum pump . Liquid nitrogen 's efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object , enveloping the object in insulating nitrogen gas . This effect , known as the Leidenfrost effect , applies to any liquid in contact with an object significantly hotter than its boiling point .

Before a series of breakthroughs in the mid-1980s , most scientists believed that the extremely low temperature requirements of superconductors rendered them impractical for everyday use .

Many properties and structures are yet to be discovered for the highly-nitrogen substituted subset of molecules .

Protons and neutrons , each with masses of approximately one atomic mass unit , are collectively referred to as `` nucleons '' . One or more protons are present in the nucleus of every atom ; they are a necessary part of the nucleus . The number of protons in the nucleus is the defining property of an element , and is referred to as the atomic number ( represented by the symbol Z ) . Since each element has a unique number of protons , each element has its own unique atomic number . The word proton is Greek for `` first '' , and this name was given to the hydrogen nucleus by Ernest Rutherford in 1920 . In previous years , Rutherford had discovered that the hydrogen nucleus ( known to be the lightest nucleus ) could be extracted from the nuclei of nitrogen by atomic collisions . Protons were therefore a candidate to be a fundamental particle , and hence a building block of nitrogen and all other heavier atomic nuclei . In the modern Standard Model of particle physics , protons are hadrons , and like neutrons , the other nucleon ( particle present in atomic nuclei ) , are composed of three quarks . Although protons were originally considered fundamental or elementary particles , they are now known to be composed of three valence quarks : two up quarks and one down quark . The rest masses of quarks contribute only about 1 % of a proton 's mass , however . The remainder of a proton 's mass is due to quantum chromodynamics binding energy , which includes the kinetic energy of the quarks and the energy of the gluon fields that bind the quarks together . Because protons are not fundamental particles , they possess a physical size , though not a definite one ; the root mean square charge radius of a proton is about 0.84 -- 0.87 fm or to . At sufficiently low temperatures , free protons will bind to electrons . However , the character of such bound protons does not change , and they remain protons . A fast proton moving through matter will slow by interactions with electrons and nuclei , until it is captured by the electron cloud of an atom . The result is a protonated atom , which is a chemical compound of hydrogen . In vacuum , when free electrons are present , a sufficiently slow proton may pick up a single free electron , becoming a neutral hydrogen atom , which is chemically a free radical . Such `` free hydrogen atoms '' tend to react chemically with many other types of atoms at sufficiently low energies . When free hydrogen atoms react with each other , they form neutral hydrogen molecules ( H2 ) , which are the most common molecular component of molecular clouds in interstellar space .", "qid": "645", "docid": "Proton", "rank": 51, "score": 83461 }, { "content": "Title: Owl Nebula Content: The Owl Nebula ( also known as Messier 97 , M97 or NGC 3587 ) is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major .

When William Parsons , 3rd Earl of Rosse , observed the nebula in 1848 , his hand-drawn illustration resembled an owl 's head . It has been known as the Owl Nebula ever since . The nebula is approximately 8,000 years old . It is approximately circular in cross-section with a little visible internal structure . It was formed from the outflow of material from the stellar wind of the central star as it evolved along the asymptotic giant branch . The nebula is arranged in three concentric shells , with the outermost shell being about 20 -- 30 % larger than the inner shell . The owl-like appearance of the nebula is the result of an inner shell that is not circularly symmetric , but instead forms a barrel-like structure aligned at an angle of 45 ° to the line of sight . The nebula holds about 0.13 solar masses of matter , including hydrogen , helium , nitrogen , oxygen , and sulfur ; all with a density of less than 100 particles per cubic centimeter . Its outer radius is around 0.28 pc and it is expanding with velocities in the range of 27 -- 39 km/s into the surrounding interstellar medium .

It was originally invented in the Soviet Union , but remained classified until it was discovered independently in the United States in 1989 at SRI International . SRI obtained US and international patents for ADN in the mid-1990s at which time scientists from the former Soviet Union revealed they had discovered ADN in the 1970s . It makes an excellent solid rocket oxidizer with a slightly higher specific impulse than ammonium perchlorate and more importantly , does not leave hydrogen chloride fumes . This property is also of military interest because halogen free smoke is harder to detect . It decomposes into low molecular mass gases so it contributes to higher performance without creating excessive temperatures if used in gun or rocket propellants . The salt is prone to detonation under high temperatures and shock more so than the perchlorate . It can be synthesized from ammonium nitrate , anhydrous nitric acid , and fuming sulfuric acid containing 20 % free sulfur trioxide . A base other than ammonia must be added before the acid dinitramide decomposes . The final product is obtained by fractional crystallization .

The color of neodymium compounds -- due to the Nd3 + ion -- is often a reddish-purple but it changes with the type of lighting , due to the interaction of the sharp light absorption bands of neodymium with ambient light enriched with the sharp visible emission bands of mercury , trivalent europium or terbium .

The high speed of the alpha is sufficient to overcome the relatively low Coulomb barrier of the beryllium nucleus , the repulsive force due to the positive charge of the nucleus , which contains only four protons , allowing for fusion of the two particles , releasing energetic neutrons . In 1930 Walther Bothe and Herbert Becker in Germany found that alpha particles striking light elements such as beryllium , boron , or lithium would release a highly penetrating radiation , at first believed to be gamma radiation , although it was more penetrating than any gamma rays known . The next important contribution was reported in 1932 by Irène Joliot-Curie and Frédéric Joliot in Paris , who showed that if this unknown radiation fell on paraffin wax or any other hydrogen-containing compound it ejected protons of very high energy . Finally , in 1932 the physicist James Chadwick in England performed a series of experiments showing that the gamma ray hypothesis was untenable , and suggested that the new radiation consisted of uncharged particles of approximately the mass of the proton . He performed a series of experiments to verify this , these uncharged particles were eventually called `` neutrons '' , and Chadwick is credited with this discovery . Any alpha-emitting radioisotope will suffice , but usually a high specific activity alpha-emitter is chosen , such as radium ( Ra-226 ) . The alpha emitter and the beryllium are pulverized and mixed together in close intimate contact to insure a high percentage of alpha-emitter and beryllium nuclei in close contact , since the alpha has a very short range through material , and would lose energy preventing reaction if sufficiently far away . This mixture of material is then packed into a suitable carrier with radiation shielding , with one end open to allow the neutrons to shoot out , thus acting like a howitzer . Neutron howitzers were used by Otto Hahn , Fritz Strassman , and Lise Meitner in 1938 to bombard uranium nuclei with neutrons in the hopes of making transuranic elements . To their surprise , they found barium residue , a clear indication that they had instead fissioned uranium nuclei .

It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 . Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time , Rutherford is generally accorded the credit because his work was published first . The name nitrogen was suggested by Jean-Antoine-Claude Chaptal in 1790 , when it was found that nitrogen was present in nitric acid and nitrates ; this name derives from the Greek roots νἰτρον `` nitre '' and - γεννᾶν `` to form '' . Antoine Lavoisier suggested instead the name azote , from the Greek άζωτικός `` no life '' , as it is an asphyxiant gas ; his name is instead used in many languages , such as French , Russian , and Turkish , and appears in the English names of some nitrogen compounds such as hydrazine , azides and azo compounds . Nitrogen is the lightest member of group 15 of the periodic table , often called the pnictogens . The name comes from the Greek πνίγειν `` to choke '' , directly referencing nitrogen 's asphyxiating properties . It is a common element in the universe , estimated at about seventh in total abundance in the Milky Way and the Solar System . At standard temperature and pressure , two atoms of the element bind to form dinitrogen , a colourless and odorless diatomic gas with the formula N2 . Dinitrogen forms about 78 % of Earth 's atmosphere , making it the most abundant uncombined element . Nitrogen occurs in all organisms , primarily in amino acids ( and thus proteins ) , in the nucleic acids ( DNA and RNA ) and in the energy transfer molecule adenosine triphosphate . The human body contains about 3 % nitrogen by mass , the fourth most abundant element in the body after oxygen , carbon , and hydrogen . The nitrogen cycle describes movement of the element from the air , into the biosphere and organic compounds , then back into the atmosphere . Many industrially important compounds , such as ammonia , nitric acid , organic nitrates ( propellants and explosives ) , and cyanides , contain nitrogen . The extremely strong triple bond in elemental nitrogen ( N ≡ N ) , the second strongest bond in any diatomic molecule , dominates nitrogen chemistry . This causes difficulty for both organisms and industry in converting N2 into useful compounds , but at the same time means that burning , exploding , or decomposing nitrogen compounds to form nitrogen gas releases large amounts of often useful energy . Synthetically produced ammonia and nitrates are key industrial fertilisers , and fertiliser nitrates are key pollutants in the eutrophication of water systems . Apart from its use in fertilisers and energy-stores , nitrogen is a constituent of organic compounds as diverse as Kevlar used in high-strength fabric and cyanoacrylate used in superglue . Nitrogen is a constituent of every major pharmacological drug class , including antibiotics . Many drugs are mimics or prodrugs of natural nitrogen-containing signal molecules : for example , the organic nitrates nitroglycerin and nitroprusside control blood pressure by metabolizing into nitric oxide . Many notable nitrogen-containing drugs , such as the natural caffeine and morphine or the synthetic amphetamines , act on receptors of animal neurotransmitters .", "qid": "646", "docid": "Nitrogen", "rank": 5, "score": 101015 }, { "content": "Title: Ammonia volatilization from urea Content: Urea ( 46-0-0 ) accounts for more than fifty percent of the world 's nitrogenous fertilizers .

Disruption due to climate change , or other anthropogenic perturbations can result in decreased productivity and in some cases lead to disruptions in global biogeochemical cycles . The possible ramifications of changes in ecosystem biodiversity are not well characterized or understood , and it may be possible that disruption , up to a point , will have little to no effect given the redundancy within an ecosystem . This is particularly troubling in the context of microbial ecosystems . The dynamics of microbial ecosystems are tightly coupled to biogeochemical processes , and any perturbation within this system in particular could result in dramatic changes ( Kirchman , 2008 ) . For example , the microbial loop within the marine context is responsible for the decomposition of organics and recycling of nutrients back into the ecosystem . This allows for other organisms , such as phytoplankton , to reuse essential nutrients , like nitrogen , and continue production ( Kirchman 2008 ) . Without this recycled nitrogen , phytoplankton would be highly limited in their production rates , in turn limiting the growth of grazers . The effects of such an occurrence would reverberate throughout the food web , and nitrogen cycle . It is important to establish a base line of microbial diversity within ecosystems in order to gauge possible change due to climate change and the possible outcomes . Recent use of high-throughput sequencing techniques has broadened the scope of biodiversity , with the discovery of what has been titled the `` Rare Biosphere '' ( Sogin et al. , 2006 ) . Previous attempts to characterize in situ abundance have been made through pure culture and molecular techniques ( Fuhrman , 2009 ) . Pure culture providing a very narrow picture of some of the rarer species present , < 1-5 % of bacteria present ( Fuhrman , 2009 ) . Molecular techniques , such as Sanger sequencing , resulting in a much broader scope but highlighting the more abundant species present ( Heidelberg et al. , 2010 ) ( Pedros-Alio , 2007 ) . Neither technique captures all of the diversity present . Alternatively high throughput sequencing , `` tag sequencing '' , divides unique rRNA tag sequences into operational taxonomic units ( OTUs ) based upon similarities in mitochondrial-encoded cytochrome oxidases ( Sogin et al. , 2006 ) . Both Sanger , shot gun sequencing , and tag sequencing organize sequences into OTUs ( Heidelberg et al. , 2010 ) . However , it is the resolution that tag sequencing provides that sets it apart , resulting from the increased efficiency in serial analysis ( Heidelberg et al. , 2010 ) . This efficiency increase is made possible through the use of internal primer sequences resulting in restriction-digest overhanging sequences ( Heidelberg et al. , 2010 ) . Though OTUs provide a means of distinguishing the possible number of phylogenetic groups , it is not possible to deduce phylogenetic relationships based upon OTU 's . Tags associated with OTUs must be cross-referenced with gene banks , in order for tags to be phylotyped and relationships established ( Sogin et al. , 2006 ) . The result of tag sequencing has been to produce orders of magnitude larger estimates of OTUs present in ecosystems , producing a long tail on species abundance curves ( Patterson , 2009 ) ( Pedrós-Alío , 2007 ) . This long tail accounts for less than .1 % of the abundant species in a particular ecosystem . At the same time it represents thousands of populations accounting for most of the phylogenetic diversity in an ecosystem . This low-abundance high-diversity group is what is now called the `` Rare Biosphere '' . Using this method , Sogin et al. 's study of microbial diversity in North Atlantic deep water produced an estimate of 5266 different taxa ( Sogin et al. , 2006 ) . This is particularly dramatic considering that previous studies employing more traditional PCR cloning techniques have resulted in estimates of up to 500 ( Pedrós-Alío , 2007 ) .", "qid": "646", "docid": "Rare_biosphere", "rank": 7, "score": 97754 }, { "content": "Title: Denitrification Content: Denitrification is a microbially facilitated process where nitrate is reduced and ultimately produces molecular nitrogen ( N2 ) through a series of intermediate gaseous nitrogen oxide products . Facultative anaerobic bacteria perform denitrification as a type of respiration that reduces oxidized forms of nitrogen in response to the oxidation of an electron donor such as organic matter . The preferred nitrogen electron acceptors in order of most to least thermodynamically favorable include nitrate ( NO3 − ) , nitrite ( NO2 − ) , nitric oxide ( NO ) , nitrous oxide ( N2O ) finally resulting in the production of dinitrogen ( N2 ) completing the nitrogen cycle . Denitrifying microbes require a very low oxygen concentration of less than 10 % , as well as organic C for energy . Since denitrification can remove NO3 − , reducing its leaching to groundwater , it can be strategically used to treat sewage or animal residues of high nitrogen content . Denitrification can leak N2O , which is an ozone-depleting substance and a greenhouse gas that can have a considerable influence on global warming . The process is performed primarily by heterotrophic bacteria ( such as Paracoccus denitrificans and various pseudomonads ) , although autotrophic denitrifiers have also been identified ( e.g. , Thiobacillus denitrificans ) . Denitrifiers are represented in all main phylogenetic groups . Generally several species of bacteria are involved in the complete reduction of nitrate to N2 , and more than one enzymatic pathway has been identified in the reduction process . Direct reduction from nitrate to ammonium , a process known as dissimilatory nitrate reduction to ammonium or DNRA , is also possible for organisms that have the nrf-gene .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years . Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) , whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change . Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' .

It was proposed as a replacement for the Laplacian version of the nebular hypothesis that had prevailed since the 19th century . The theory was based on the idea that a star passed close enough to the sun early in its life to cause tidal bulges to form on its surface , which along with the internal process that leads to solar prominences , caused material to be ejected repeatedly from the sun . Due to the gravitational effects of the passing star , two spiral-like arms would have extended from the sun , and while most of the material would have fallen back , part of it would remain in orbit . This orbiting material would cool and condense into numerous small bodies that they termed planetesimals and a few larger protoplanets . Their theory proposed that as these objects collided over time , the planets and their moons were built up , with comets and asteroids being the leftover debris . The `` spiral nebulae '' photographed at Lick Observatory were thought to possibly be views of other suns undergoing this process . These nebulae are now known to be galaxies rather than developing solar systems . In 1917 , James Hopwood Jeans argued that only a very close approach of a second star was necessary to eject material , instead of requiring solar prominences . In 1939 , Lyman Spitzer showed that a column of material drawn out from the sun would dissipate rather than condense . By this time the theory had mostly fallen out of favor , and in the 1940s , the work of Henry Norris Russell showed that if the solar material had been pulled away from the sun with the force necessary to account for the angular momentum of Jupiter , the material would have continued out of the solar system entirely .

It is a colorless clear liquid with a density of 0.807 g/ml at its boiling point ( -195.79 C ) and a dielectric constant of 1.43 . Nitrogen was first liquefied at the Jagiellonian University on 15 April 1883 by Polish physicists , Zygmunt Wróblewski and Karol Olszewski . It is produced industrially by fractional distillation of liquid air . Liquid nitrogen is often referred to by the abbreviation , LN2 or `` LIN '' or `` LN '' and has the UN number 1977 . Liquid nitrogen is a diatomic liquid , which means that the diatomic character of the covalent N bonding in N2 gas is retained after liquefaction . Liquid nitrogen is a cryogenic fluid that can cause rapid freezing on contact with living tissue . When appropriately insulated from ambient heat , liquid nitrogen can be stored and transported , for example in vacuum flasks . The temperature is held constant at 77 K by slow boiling of the liquid , resulting in the evolution of nitrogen gas . Depending on the size and design , the holding time of vacuum flasks ( Dewars ) ranges from a few hours to a few weeks . The development of pressurised super-insulated vacuum vessels has enabled liquefied nitrogen to be stored and transported over longer time periods with losses reduced to 2 % per day or less . The temperature of liquid nitrogen can readily be reduced to its freezing point 63 K by placing it in a vacuum chamber pumped by a vacuum pump . Liquid nitrogen 's efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object , enveloping the object in insulating nitrogen gas .

Many other theories of climate change were advanced , involving forces from volcanism to solar variation . In the 1960s , the warming effect of carbon dioxide gas became increasingly convincing . Some scientists also pointed out that human activities that generated atmospheric aerosols ( e.g. , `` pollution '' ) could have cooling effects as well . During the 1970s , scientific opinion increasingly favored the warming viewpoint . By the 1990s , as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages , a consensus position formed : greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming . Since the 1990s , scientific research on climate change has included multiple disciplines and has expanded . Research has expanded our understanding of causal relations , links with historic data and ability to model climate change numerically . Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change .

One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans .

The model was developed by Isaac Held and Arthur Hou in 1980 . The essence of the model is that air rising from the surface at the equator conserves its angular momentum as it moves poleward . This distribution of wind , in turn , determines the distribution of temperature , which determines the latitudinal extent of the circulation by requiring energy conservation . This stands in contrast to George Hadley 's original conception of the circulation , which he argued reached the poles . The Hadley circulation has a cooling effect at and near the equator and a warming effect at higher latitudes within the Hadley Cell . This energy transport can be converted into a mass transport , to determine the strength of the circulation , by normalizing by the appropriate vertical stability . The effects of moisture and seasons on the model have been studied . Earth 's atmosphere violates the underlying assumptions of the model : angular momentum is not conserved and the tropical atmosphere is not energetically closed .

These include the chemistry at Earth 's surface , the rate of cooling of the planet 's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun 's luminosity . An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans , such as climate engineering , which could cause significant changes to the planet . The current Holocene extinction is being caused by technology and the effects may last for up to five million years . In turn , technology may result in the extinction of humanity , leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes . Over time intervals of hundreds of millions of years , random celestial events pose a global risk to the biosphere , which can result in mass extinctions . These include impacts by comets or asteroids with diameters of 5 -- or more , and the possibility of a massive stellar explosion , called a supernova , within a 100-light-year radius of the Sun , called a Near-Earth supernova . Other large-scale geological events are more predictable . If the long-term effects of global warming are disregarded , Milankovitch theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end . These periods are caused by variations in eccentricity , axial tilt , and precession of the Earth 's orbit . As part of the ongoing supercontinent cycle , plate tectonics will probably result in a supercontinent in 250 -- 350 million years . Some time in the next 1.5 -- 4.5 billion years , the axial tilt of the Earth may begin to undergo chaotic variations , with changes in the axial tilt of up to 90 ° . During the next four billion years , the luminosity of the Sun will steadily increase , resulting in a rise in the solar radiation reaching the Earth . This will result in a higher rate of weathering of silicate minerals , which will cause a decrease in the level of carbon dioxide in the atmosphere . In about 600 million years from now , the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees . Some plants use the C4 carbon fixation method , allowing them to persist at concentrations as low as 10 parts per million . However , the long-term trend is for plant life to die off altogether . The extinction of plants will be the demise of almost all animal life , since plants are the base of the food chain on Earth . In about one billion years , the solar luminosity will be 10 % higher than at present . This will cause the atmosphere to become a `` moist greenhouse '' , resulting in a runaway evaporation of the oceans . As a likely consequence , plate tectonics will come to an end , and with them the entire carbon cycle . Following this event , in about 2 − 3 billion years , the planet 's magnetic dynamo may cease , causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere . Four billion years from now , the increase in the Earth 's surface temperature will cause a runaway greenhouse effect , heating the surface enough to melt it . By that point , all life on the Earth will be extinct .

Air pollution research in relation to critical loads has focused on nitrogen and sulfur pollutants . After these pollutants are emitted into the atmosphere , they are subsequently deposited into ecosystems . Both sulfur and nitrogen deposition can acidify surface waters and soils . As added acidity lowers the pH of water , fish and invertebrate health are negatively impacted . Sulfur and nitrogen , as acidifying agents , may change soil nutrient content by removing calcium and releasing toxic aluminum , further impacting plants and animals . Nitrogen deposition can also act as a fertilizer in the environment and alter the competitive interactions of plants , thereby favoring the growth of some plant species and inhibiting others , potentially leading to changes in species composition and abundance . The deposition of nitrogen contributes to nutrient enrichment in freshwater , coastal , and estuarine ecosystems , which may cause toxic algal blooms , fish kills , and loss of biodiversity . Air pollutants impact essential ecosystem services such as air and water purification , decomposition and detoxification of waste materials , and climate regulation . When deposition is greater than the critical load of a pollutant for a particular location , it is considered a critical load exceedance , meaning the biota are at increased risk of ecological harm . Some components of an ecosystem are more sensitive to deposition than others ; therefore , critical loads can be developed for a variety of ecosystem components and responses , including ( but not limited to ) shifts in diatoms , increases in invasive grass species , changes in soil chemistry , decreased forest health , altered and reduced biodiversity , and lake and stream acidification .

It can , amongst other things , be used in analysing sediments and compost . A useful application for C/N ratios is as a proxy for paleoclimate research , having different uses whether the sediment cores are terrestrial-based or marine-based . Carbon-to-nitrogen ratios are an indicator for nitrogen limitation of plants and other organisms and can identify whether molecules found in the sediment under study come from land-based or algal plants . Further , they can distinguish between different land-based plants , depending on the type of photosynthesis they undergo . Therefore , the C/N ratio serves as a tool for understanding the sources of sedimentary organic matter , which can lead to information about the ecology , climate , and ocean circulation at different times in Earth 's history . C/N ratios in the range 4-10 :1 are usually from marine sources , whereas higher ratios are likely to come from a terrestrial source . Vascular plants from terrestrial sources tend to have C/N ratios greater than 20 . The lack of cellulose , which has a chemical formula of ( C6H10O5 ) n , and greater amount of proteins in algae versus vascular plants causes this significant difference in the C/N ratio . When composting , microbial activity utilizes a C/N ratio of 30-35 :1 and a higher ratio will result in slower composting rates . However , this assumes that carbon is completely consumed , which is often not the case . Thus , for practical agricultural purposes , a compost should have an initial C/N ratio of 20-30 :1 . Example of devices that can be used to measure this ratio are the CHN analyzer and the continuous-flow isotope ratio mass spectrometer ( CF-IRMS ) .

The test predicts whether the addition of nitrogen fertilizer to agricultural land will result in increased crop yields . Nitrogen is essential for plant development . Indeed , for crops that are destined to be food for farm animal or human consumption , incorporation of nitrogen into the crop is an important goal , since this forms the basis for protein in the human diet . Nitrogen is commonly present in soils in many forms , and there are many ways to measure this nitrogen . None of these are completely satisfactory as a measure of the nitrogen that is available for use by crops . The ISNT is a new ( 2007 ) method for measuring nitrogen available for plant uptake . ISNT estimates the amount of nitrogen present in the soil as amino sugar nitrogen . With respect to corn and soybeans , the optimal range for plant growth appears to be around 225 to 240 mg/Kg . Some form of nitrogen fertilizer is needed if levels are below this range . On the other hand , if levels are above this range , addition of nitrogen fertilizer will not increase crop yield . In the corn belt , since about 1975 , the predominant method of estimating the amount of nitrogen needed for corn has been the `` yield-based '' method . A farmer first estimates the yield of corn he intends to produce . He then applies 1.1 to 1.4 lbs of nitrogen per bushel of expected yield . ISNT represents an alternative approach to managing nitrogen application . However , ISNT does not offer a simple answer as to the amount of nitrogen fertilizer that is needed , or as to the optimal form of that fertilizer . In field trials in Illinois , some fields have been found to be under-fertilized when managed according to the `` yield-based '' method , as judged by the ISNT . In the majority of trials , however , the yield-based method calls for the addition of nitrogen far in excess of the levels needed for optimal crop production . This nitrogen , which is applied by farmers at great cost , does not find its way into the crop , but is lost to the atmosphere or leaches into waterways . Within the corn belt , stalks and other crop residues are left in the field with the intention of enhancing the amount of organic material in the soil . Excessive nitrogen application , however , appears to promote the rapid decomposition of organic matter in the soil , resulting in release of carbon dioxide .

They are also a member of the carbon nitride class of materials that include beta carbon nitride ( β-C3N4 ) , predicted to be harder than diamond . Besides the pioneering work of a couple of academic groups , this class of compounds has so far garnered little attention from the broader fullerene research community . Many properties and structures are yet to be discovered for the highly-nitrogen substituted subset of molecules . The first fullerene molecule to be discovered , and the family 's namesake , buckminsterfullerene ( C60 ) , was prepared in 1985 by Richard Smalley , Robert Curl , James Heath , Sean O'Brien , and Harold Kroto at Rice University . A fullerene is any molecule composed entirely of carbon , in the form of a hollow sphere , ellipsoid , tube , and many other shapes . Spherical fullerenes are also called buckyballs , and they resemble the balls used in football ( soccer ) . Fullerenes are similar in structure to graphite , which is composed of stacked graphene sheets of linked hexagonal rings ; but they may also contain pentagonal ( or sometimes heptagonal ) rings . Azafullerenes were first discovered in 1993 and reported in the California State Science Fair . The derivatives were formed in the gap between two graphite rods connected to an electric power supply . A small air leak led to contamination of the inert atmosphere and the subsequent reaction .

Most fossil fuels are combusted with ambient air ( as differentiated from combustion with pure oxygen ) . Since ambient air contains about 79 volume percent gaseous nitrogen ( N2 ) , which is essentially non-combustible , the largest part of the flue gas from most fossil-fuel combustion is uncombusted nitrogen . Carbon dioxide , the next largest part of flue gas , can be as much as 10 − 25 volume percent or more of the flue gas . This is closely followed in volume by water vapor ( H2O ) created by the combustion of the hydrogen in the fuel with atmospheric oxygen . Much of the ` smoke ' seen pouring from flue gas stacks is this water vapor forming a cloud as it contacts cool air . A typical flue gas from the combustion of fossil fuels contains very small amounts of nitrogen oxides ( NOx ) , sulfur dioxide ( SO2 ) and particulate matter . The nitrogen oxides are derived from the nitrogen in the ambient air as well as from any nitrogen-containing compounds in the fossil fuel . The sulfur dioxide is derived from any sulfur-containing compounds in the fuels . The particulate matter is composed of very small particles of solid materials and very small liquid droplets which give flue gases their smoky appearance . The steam generators in large power plants and the process furnaces in large refineries , petrochemical and chemical plants , and incinerators burn considerable amounts of fossil fuels and therefore emit large amounts of flue gas to the ambient atmosphere . The table below presents the total amounts of flue gas typically generated by the burning of fossil fuels such as natural gas , fuel oil and coal .

They fix nitrogen from dinitrogen ( N2 ) in the air using the enzyme nitrogenase , in order to provide the cells in the filament with nitrogen for biosynthesis . Nitrogenase is inactivated by oxygen , so the heterocyst must create a microanaerobic environment . The heterocysts ' unique structure and physiology require a global change in gene expression . For example , heterocysts : produce three additional cell walls , including one of glycolipid that forms a hydrophobic barrier to oxygen produce nitrogenase and other proteins involved in nitrogen fixation degrade photosystem II , which produces oxygen up-regulate glycolytic enzymes produce proteins that scavenge any remaining oxygen contain polar plugs composed of cyanophycin which slows down cell-to-cell diffusion Cyanobacteria usually obtain a fixed carbon ( carbohydrate ) by photosynthesis . The lack of photosystem II prevents heterocysts from photosynthesizing , so the vegetative cells provide them with carbohydrates , which is thought to be sucrose . The fixed carbon and nitrogen sources are exchanged through channels between the cells in the filament . Heterocysts maintain photosystem I , allowing them to generate ATP by cyclic photophosphorylation . Single heterocysts develop about every 9-15 cells , producing a one-dimensional pattern along the filament . The interval between heterocysts remains approximately constant even though the cells in the filament are dividing . The bacterial filament can be seen as a multicellular organism with two distinct yet interdependent cell types . Such behavior is highly unusual in prokaryotes and may have been the first example of multicellular patterning in evolution . Once a heterocyst has formed it can not revert to a vegetative cell . Certain heterocyst-forming bacteria can differentiate into spore-like cells called akinetes or motile cells called hormogonia , making them the most phenotyptically versatile of all prokaryotes . The mechanism of controlling heterocysts is thought to involve the diffusion of an inhibitor of differentiation called patS . Heterocyst formation is inhibited in the presence of a fixed nitrogen source , such as ammonium or nitrate . Heterocyst maintenance is dependent on an enzyme called hetN . The bacteria may also enter a symbiotic relationship with certain plants . In such a relationship , the bacteria do not respond to the availability of nitrogen , but to signals produced by the plant . Up to 60 % of the cells can become heterocysts , providing fixed nitrogen to the plant in return for fixed carbon . The following sequences take place in formation of heterocysts from a vegetative cell : The cell enlarges . Granular inclusions decrease . Photosynthetic lammele reorients . The wall finally becomes triple-layered . These three layers develop outside the cell 's outer layer . The middle layer is homogeneous . The inner layer is laminated .

The percentages of partitioning can be determined with the equation with dW/dt is the growth rate ( dW/dt ) i and Pci are the rates of biomass partitioned and the respective partitioning factor for each plant organ i. Overall , nitrogen availability has a strong effect on partitioning , with plants growing in low-nitrogen areas partitioning most of their biomass to underground structures . Soil nitrogen availability is a strong determinant of biomass allocation . For example , in low productivity systems such as boreal forests , trees devote a large portion of their biomass to roots . But as the soil productivity begins to increase , biomass is primarily allocated to aboveground structures such as leaves and stems . As an overall pattern , the overall lengths of roots begin to decrease as nitrogen concentrations increase . In addition to nitrogen as a factor of plant biomass partitioning , other environmental stressors such as water availability play a role . For example , plants that are growing in dry conditions often have a decreased total biomass production but they also contribute more of their biomass to the roots and develop a higher root : shoot . When plants allocate more of their biomass to their roots , they are able to enhance water absorption by tapping further down into the water table as well as extending further laterally with the aid of increased root hairs . But , when there is an extreme soil drought , there is not an increase in root : shoot biomass . This suggests that there is a limit to which plant biomass allocation responds to water stress and possibly other environmental factors as well .

The fixation process frees nitrogen atoms from their triply bonded diatomic form , N ≡ N , to be used in other ways .

A properly functioning Septic System that has an adequate surface area of biological mat interface will deliver partially treated effluent without overflowing to the surface and short circuiting effluent into surface waters . There are estimates that 80 % of nitrogen in waters surrounding the Cape is from onsite Septic Systems . This is totally flawed as there are many other sources of nitrogen , both anthropogenic and natural . There are huge quantities of nitrogen released from vegetation , animals and bacteria that occur in natural systems and from atmospheric deposition .

In Cape Cod , Massachusetts , small ponds in the inland areas and the surrounding waters of the Atlantic Ocean have become increasingly polluted over the years . The main pollutant considered to be problematic in these waters is nitrogen . The large amount of nitrogen in the water stems from the widespread use of private septic tanks in homes instead of the use of a town-owned sewer . This is because many Cape Cod towns opted out of purchasing sewer systems when the federal government subsidized them in the 1960s and 1970s for fear of attracting too many new homeowners to the communities . However , Cape Cod communities still grew despite the lack of public sewage systems , which resulted in the installation of many septic tanks in new homes . The increased nitrogen levels in the Cape Cod waters has resulted in a greater amount of algae blooming in the spring and summer months , since nitrogen is a nutrient for algae . When the algae die , they leave a thick coat of slime on the bottom of the bays and ponds , which severely reduces the amount of shellfish and crabs able to survive on the seafloor . The algae also limit the amount of oxygen available in the water , which kills the fish living beneath them . The algae are the source of red tides , which have been occurring more frequently with the heightened levels of nitrogen . To counter the problem , towns are trying to institute new programs and procedures to reduce the levels of nitrogen present in the waters of Cape Cod .

The carbon neutrality concept may be extended to include other greenhouse gases ( GHG ) measured in terms of their carbon dioxide equivalence ( e ) -- the impact a GHG has on the atmosphere expressed in the equivalent amount of CO2 .

HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather to specific mechanical properties . They have a carbon content between 0.05 -- 0.25 % to retain formability and weldability . Other alloying elements include up to 2.0 % manganese and small quantities of copper , nickel , niobium , nitrogen , vanadium , chromium , molybdenum , titanium , calcium , rare earth elements , or zirconium . Copper , titanium , vanadium , and niobium are added for strengthening purposes . These elements are intended to alter the microstructure of carbon steels , which is usually a ferrite-pearlite aggregate , to produce a very fine dispersion of alloy carbides in an almost pure ferrite matrix . This eliminates the toughness-reducing effect of a pearlitic volume fraction yet maintains and increases the material 's strength by refining the grain size , which in the case of ferrite increases yield strength by 50 % for every halving of the mean grain diameter . Precipitation strengthening plays a minor role , too . Their yield strengths can be anywhere between 250 -- . Because of their higher strength and toughness HSLA steels usually require 25 to 30 % more power to form , as compared to carbon steels . Copper , silicon , nickel , chromium , and phosphorus are added to increase corrosion resistance . Zirconium , calcium , and rare earth elements are added for sulfide-inclusion shape control which increases formability . These are needed because most HSLA steels have directionally sensitive properties . Formability and impact strength can vary significantly when tested longitudinally and transversely to the grain . Bends that are parallel to the longitudinal grain are more likely to crack around the outer edge because it experiences tensile loads . This directional characteristic is substantially reduced in HSLA steels that have been treated for sulfide shape control . They are used in cars , trucks , cranes , bridges , roller coasters and other structures that are designed to handle large amounts of stress or need a good strength-to-weight ratio . HSLA steel cross-sections and structures are usually 20 to 30 % lighter than a carbon steel with the same strength . HSLA steels are also more resistant to rust than most carbon steels because of their lack of pearlite -- the fine layers of ferrite ( almost pure iron ) and cementite in pearlite .

Various species of insects have been known to utilize molecular compounds from plants for their own defense and even as their pheromones or precursors to their pheromones . A few Lepidoptera have been found to sequester chemicals from plants which they retain throughout their life and Arctiidae is no exception to this strategy . Starting in the mid-twentieth century researchers investigated various members of Arctiidae , and how these insects sequester pyrrolizidine alkaloids ( PAs ) during their life stages , and utilize these chemicals as adults for pheromones or pheromone precursors . PAs are also used by members of the Arctiidae for defense against predators throughout the life of the insect . Pyrrolizidine alkaloids are a group of chemicals produced by plants as secondary metabolites , all of which contain a pyrrolizidine nucleus . This nucleus is made up of two pyrrole rings bonded by one carbon and one nitrogen . There are two forms in which PAs can exist and will readily interchange between : a pro-toxic free base form , also called a tertiary amine , or in a non-toxic form of N-oxide . Researchers have collected data that strongly suggests that PAs can be registered by taste receptors of predators , acting as a deterrent from being ingested . Taste receptors are also used by the various moth species that sequester PAs , which often stimulates them to feed . As of 2005 , all of the PA sequestering insects that have been studied have all evolved a system to keep concentrations of the PA pro-toxic form low within the insect 's tissues . Researchers have found a number of Arctiidae that utilize PAs for protection and for male pheromones or precursors of the male pheromones , and some studies have found evidence suggesting PAs have behavioral and developmental effects . Estigmene acrea , Cosmosoma myrodora , Utetheisa ornatrix , Creatonotos gangis and Creatonotos transiens are all members of the family Arctiidae and found to use PAs for their defense and/or male pheromones . Parsimony suggests that the sequestering of PAs in the larval stage evolved in the subfamily Arctiinae common ancestor . The loss of ability to sequester and utilize PAs has occurred in a number of species , along with the switch from larval uptake to adult uptake of PAs occurring multiple times within the Arctiinae taxon . Members of Arctiidae typically sequester PAs from their diets , but sometimes must specifically ingest fluids excreted by plants that are not a part of their diets . Sequestered PAs are kept in various tissues and varying concentration which is dependent upon the species . PAs are found in the cuticle of all studied Arctiidae mentioned here , but some also package these chemicals into their spermatophores as seen in Creatonotos gangis and Creatonotos transiens . The display of PAs on the exoskeleton is believed to cue predators to the unpalatability of the prey . Eisner and Eisner looked at the palatability of PA positive and negative U. ornatrix to wolf spiders , Lycosa ceratiola , in both the larval form and adult form . They found that the pyrrolizidine-positive organisms were typically released unharmed by spiders except in two field circumstances where the larvae were probably envenomated prior to the spider 's release and died two days after the attack . All of the PA-negative organisms were eaten by spiders . These findings were in line with prior studies done by Eisner and Meinwald which looked at orb weavers and U. ornatrix , along with spiders being fed beetle larva covered in PAs , which they rejected . All of these findings support PAs being utilized for defense against predation . Studies have further elucidated the defenses and uses of PAs in Arctiidae . One study researched C. myrodora and how PAs protect this species from spider predation among other things . It found that PAs ingested from fluids excreted by plants aided in defense from predation . All organisms permitted access to PA-containing diets that were fed to spiders were cut loose from the webs . Females that had PA-deprived diets , but were allowed to mate with PA-positive males , were also released from the spider 's webs . Further observations showed that male C. myrodora have a pair of pouches where they produce PA-laden filaments , which are typically released over the female prior to copulation as a nuptial gift . Experiments show that the filaments give the females more PAs , explaining why spiders released mated PA-negative females from their webs . Most of the PAs from the males were subsequently transferred to the eggs when deposited . Three clusters of eggs that were laid after copulation with a PA-positive male all tested positive for alkaloids and the one cluster that resulted from a PA-negative male copulation tested negative . By the eggs getting a dose of PAs , the authors suggest that the eggs are being protected from predators such as Coccinellidae beetles . Jordan and others ' study found a very interesting effect of the larval ingestion of PAs . Male Estigmene acrea moths that consumed PAs in their diet as larvae produced hydroxydanaidal , a volatile PA compound , and displayed their coremata : a bifid , inflatable male-specific organ , utilized in dispersing pheromones in the adult stage . Larvae that were fed diets without PAs rarely displayed their coremata and did not produce hydroxydanaidal . E. acrea have been observed in the wild displaying their coremata , an activity which attracts both males and females and is known as lekking . Lekking was described by Willis and Birch in 1982 , but larvae raised in the laboratory prior to this study rarely engaged in lekking or corematal displays . Scientists were unsure of why this phenomenon did n't occur in the lab , but laboratory raised larvae were usually reared on commercially available food which lacks PAs . The authors suggest that the PAs are used by the males to attract other moths by releasing the volatile PA hydroxydanaidal into the air . It is suggested in this study that this strategy of mate attraction came about by tapping into the PA affinity already programmed into the moths for feeding , which is further supported by the observation that E. acrea females release their pheromones a little bit later in the evening than the males . Similar uses of coremata to attract other moths have been observed in C. gangis and C. transiens along with altered development of coremata when larvae are reared without PAs . Boppre and Schneider observed adult males of these two species that were not permitted to eat PAs . Their coremata only developed into two , stalk-like projections with very few hairs arising from these stalks . Males that were given plants that produced PAs to feed upon , developed long coremata with four tubes , each longer than the males body , and each tube was highly pubescent . The authors suggest from this observation that there is a basic corematal phenotype , the two stalked coremata , and that PAs are required to form full coremata which is much larger and more elaborate than the basic corematal expression . These observations were further investigated by feeding larvae different amounts of PAs which had a direct correlation to the development of the coremata , which reached a maximum plateau around 2 mg of PAs ingested while in larval form . Similar to Jordan and others ' findings , the males raised on a diet devoid of PAs did not produce hydroxydanaidal .", "qid": "648", "docid": "Pyrrolizidine_alkaloid_sequestration", "rank": 84, "score": 66569 }, { "content": "Title: Biotin—(methylcrotonoyl-CoA-carboxylase) ligase Content: In enzymology , a biotin - -LSB- methylcrotonoyl-CoA-carboxylase -RSB- ligase is an enzyme that catalyzes the chemical reaction ATP + biotin + apo - -LSB- 3-methylcrotonoyl-CoA : carbon-dioxide ligase ( ADP-forming ) -RSB- AMP + diphosphate + -LSB- 3-methylcrotonoyl-CoA : carbon-dioxide ligase ( ADP-forming ) -RSB- The 3 substrates of this enzyme are ATP , biotin , and -LSB- -LSB- apo - -LSB- 3-methylcrotonoyl-CoA : carbon-dioxide ligase ( ADP-forming ) -RSB- -RSB- -RSB- , whereas its 3 products are AMP , diphosphate , and 3-methylcrotonoyl-CoA : carbon-dioxide ligase ( ADP-forming ) .

The process involves injecting either ammonia or urea into the firebox of the boiler at a location where the flue gas is between 1400 and to react with the nitrogen oxides formed in the combustion process . The resulting product of the chemical redox reaction is molecular nitrogen ( N2 ) , carbon dioxide ( CO2 ) , and water ( H2O ) . Urea ( NH2CONH2 ) is easier to handle and store than the more dangerous ammonia ( NH3 ) . In the process it reacts like ammonia : NH2CONH2 + H2O - > 2NH3 + CO2 The reduction happens according to ( simplified ) 4 NO + 4 NH3 + O2 - > 4 N2 + 6 H2O The reaction mechanism itself involves NH2 radicals that attach to NO and then decompose . The reaction requires a sufficient reaction time within a certain temperature range , typically 1400 and , to be effective . At lower temperatures the NO and the ammonia do not react . Ammonia that has not reacted is called ammonia slip and is undesirable , as the ammonia can react with other combustion species , such as sulfur trioxide ( SO3 ) , to form ammonium salts . At temperatures above 1093 ° C ammonia decomposes : 4 NH3 + 5 O2 - > 4 NO + 6 H2O In that case NO is created instead of removed . A further complication is mixing . In general , more NO will form in the center and less near the walls , as the walls are cooler than the center . Thus , more ammonia must find its way to the center and less near the walls , otherwise NO in the center meets insufficient ammonia for reduction and excess ammonia near the walls slips through .

It remained under occupation by the Moulton family until at least 1313 . Due to the lack of any formal excavation and the paucity of sources , much remains unclear about the site . It is unknown whether it was a true castle or merely a fortified manor house , why it was so isolated and so far from the village , and why and when it fell into disuse . It was in need of repair in 1461 and mostly gone by 1531 . There are no ruins visible today , and the site consists of nothing more than a large D-shaped moat and earthwork , barely perceptible from nearby roads . The only investigations into the site took place during World War II when the Home Guard discovered thirteenth-century pottery while digging a bunker , and a later fieldwalking expedition from a local school .

A Boulton & Watt steam engine was installed to assist water power . Rapid expansion followed with the addition of Mill ` B ' ( 1794 ) adjacent to a warehouse built to service the original mill ( all now demolished . ) It was to eventually supplant Yorkshire 's previous cottage industry of hand driven spindles . As the business continued to expand further mills , warehouses , engine houses , and reservoirs were added on the south side of Hol Beck . The six storey Mill ` C ' was added in 1815 -- 16 , Mill 'D ' followed in 1826 -- 27 , and Mill ` E ' ( which is aligned to the roadside and joined Mill ` C ' to Mill 'D ' ) in 1829 -- 31 . Temple Mill , in the form of an Egyptian Temple , was built between 1838 -- 41 . Later , the complex employed over 2,000 factory workers . When it was completed it was considered to be one of the largest factories in the world , with 7,000 steam-powered spindles . The addition of the Temple Mill completed development of mills by Marshall & Sons on this site . All of the mill buildings added from 1815 still exist . In the early years , child labour was employed . In 1832 Marshall 's political opponents alleged that : ` In Mr Marshall 's mill , a boy of 9 years of age was stripped to the skin , bound to an iron pillar , and mercilessly beaten with straps , until he fainted . ' But other reports claim that Marshall treated his workers better than most factory owners : overseers were forbidden to use corporal punishment to control the workers , and Marshall installed fans and attempted to regulate the temperature of the mill . In 1844 , Marshall and a neighbouring engineering firm , Taylor , Wordsworth and Co broke new ground by organising an away weekend in Liverpool for their workers , a novelty which caused even the editor of the normally liberal Leeds Mercury some concern : ` Entirely approving of excursions for the working class , and with the kindest feelings towards the workmen of Messrs Marshall and Messrs Taylor and Wordsworth , we would express our earnest hope that the Sunday spent in Liverpool may not in any respect be spent in a manner unbecoming the day ... There are many excellent men among the above bodies of workmen , and great responsibility will rest upon them for the issue of this new and somewhat doubtful experiment , of a large body of people being away from home on the Sabbath , and on two whole nights .

He built bicycles for them under the Paris Sport brand that were used by the US Olympic Cycling Team . In 1980 he went to work for Masi Bicycles in California until 1981 . Shortly thereafter he rented space from Masi to start his own frame-building business . By 1983 he was doing well enough to move his business to a stand-alone location in San Marcos , California . That year he went into partnership with Olympic cyclist John Howard and manufactured bicycle frames under the John Howard name until 1984 .

Atmospheric methane concentrations are of interest because it is one of the most potent greenhouse gases in Earth 's atmosphere . The 100-year global warming potential of methane is 28 . That is , over a 100-year period , it traps 28 times more heat per mass unit than carbon dioxide and 32 times the effect when accounted for aerosol interactions . Global methane levels , had risen to 1800 parts per billion ( ppb ) by 2011 , an increase by a factor of 2.5 since pre-industrial times , from 722 ppb , the highest value in at least 800,000 years . Its concentration is higher in the Northern Hemisphere since most sources ( both natural and human ) are located on land and the Northern Hemisphere has more land mass . The concentrations vary seasonally , with , for example , a minimum in the northern tropics during April − May mainly due to removal by the hydroxyl radical . Early in the Earth 's history carbon dioxide and methane likely produced a greenhouse effect . The carbon dioxide would have been produced by volcanoes and the methane by early microbes . During this time , Earth 's earliest life appeared . These first , ancient bacteria added to the methane concentration by converting hydrogen and carbon dioxide into methane and water . Oxygen did not become a major part of the atmosphere until photosynthetic organisms evolved later in Earth 's history . With no oxygen , methane stayed in the atmosphere longer and at higher concentrations than it does today . Methane is created near the surface , and it is carried into the stratosphere by rising air in the tropics . Uncontrolled build-up of methane in Earth 's atmosphere is naturally checked -- although human influence can upset this natural regulation -- by methane 's reaction with hydroxyl radicals formed from singlet oxygen atoms and with water vapor .", "qid": "656", "docid": "Atmospheric_methane", "rank": 1, "score": 195988 }, { "content": "Title: Arctic methane emissions Content: Arctic methane release is the release of methane from seas and soils in permafrost regions of the Arctic .

Global warming accelerates its release , due to both release of methane from existing stores , and from methanogenesis in rotting biomass . Large quantities of methane are stored in the Arctic in natural gas deposits , permafrost , and as undersea clathrates . Permafrost and clathrates degrade on warming , thus large releases of methane from these sources may arise as a result of global warming . Other sources of methane include submarine taliks , river transport , ice complex retreat , submarine permafrost and decaying gas hydrate deposits .

It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide . A GWP is calculated over a specific time interval , commonly 20 , 100 , or 500 years . GWP is expressed as a factor of carbon dioxide ( whose GWP is standardized to 1 ) . In the Fifth Assessment Report of the Intergovernmental Panel on Climate Change , methane has a lifetime of 12.4 years and with climate-carbon feedbacks a global warming potential of 86 over 20 years and 34 over 100 years in response to emissions . User related choices such as the time horizon can greatly affect the numerical values obtained for carbon dioxide equivalents . For a change in time horizon from 20 to 100 years , the GWP for methane decreases by a factor of approximately 2.5 . The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth 's atmosphere or have a large GWP . The GWP depends on the following factors : the absorption of infrared radiation by a given species the spectral location of its absorbing wavelengths the atmospheric lifetime of the species Thus , a high GWP correlates with a large infrared absorption and a long atmospheric lifetime . The dependence of GWP on the wavelength of absorption is more complicated . Even if a gas absorbs radiation efficiently at a certain wavelength , this may not affect its GWP much if the atmosphere already absorbs most radiation at that wavelength . A gas has the most effect if it absorbs in a `` window '' of wavelengths where the atmosphere is fairly transparent . The dependence of GWP as a function of wavelength has been found empirically and published as a graph . Because the GWP of a greenhouse gas depends directly on its infrared spectrum , the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change .", "qid": "656", "docid": "Global_warming_potential", "rank": 5, "score": 154041 }, { "content": "Title: Carbon monitoring Content: Carbon monitoring refers to tracking how much carbon dioxide or methane is produced by particular activity at a particular point in time .

Almost all other organisms depend on carbohydrate derived from photosynthesis as their primary source of energy and carbon compounds . The current episode of global warming is attributed to increasing emissions of and other greenhouse gases into Earth 's atmosphere . The global annual mean concentration of in the atmosphere has increased by more than 40 % since the start of the Industrial Revolution , from 280 ppm , the level it had for the last 10,000 years leading up to the mid-18th century , to 399 ppm as of 2015 . The present concentration is the highest in at least the past 800,000 years and likely the highest in the past 20 million years . The increase has been caused by anthropogenic sources , particularly the burning of fossil fuels and deforestation . The daily average concentration of atmospheric CO2 at Mauna Loa Observatory first exceeded 400 ppm on 10 May 2013 . It is currently rising at a rate of approximately 2 ppm/year and accelerating .

Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years . In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing . Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years .

The scientific consensus is that the global average surface temperature has risen over the last century . Scientific opinion on climate change was summarized in the 2001 Third Assessment Report of the Intergovernmental Panel on Climate Change ( IPCC ) . The main conclusions on global warming at that time were as follows : The global average surface temperature has risen 0.6 ± 0.2 ° C since the late 19th century , and 0.17 ° C per decade in the last 30 years . `` There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities '' , in particular emissions of the greenhouse gases carbon dioxide and methane . If greenhouse gas emissions continue the warming will also continue , with temperatures projected to increase by 1.4 ° C to 5.8 ° C between 1990 and 2100 . Accompanying this temperature increase will be increases in some types of extreme weather and a projected sea level rise . The balance of impacts of global warming become significantly negative at larger values of warming . These findings are recognized by the national science academies of all the major industrialized nations ; the consensus has strengthened over time and is now virtually unanimous .

It has been found that carbon dioxide from the burning of coal , natural gas , and oil for electricity and heat is the largest single source of global greenhouse gas emissions . For years , governments and corporations have been attempting to balance out their emissions by participating in carbon-offsetting -- the practice in which they invest in renewable energy to compensate for the global-warming pollution that they produce . Despite these efforts the results are still far off and we continue to see growth in CO2 concentration . Now , a growing number of individuals are trying to make a reduction in the amount of CO2 that is being produced by participating in low carbon dieting . This small adjustment in household CO2 production has the potential to reduce emissions much more quickly than other kinds of changes and it deserves explicit consideration as part of climate policy .

One class is synthetic fuel ( including methane , gasoline , diesel fuel , jet fuel or ammonia ) produced from sustainable or nuclear energy used to hydrogenate waste carbon dioxide recycled from power plant flue exhaust gas or derived from carbonic acid in seawater . Other types can be produced from renewable energy sources such as wind turbines , solar panels , and hydroelectric power stations . Such fuels are potentially carbon-neutral because they do not result in a net increase in atmospheric greenhouse gases . Until captured carbon is used for plastics feedstock , carbon neutral fuel synthesis is the primary means of carbon capture and utilization or recycling . To the extent that carbon-neutral fuels displace fossil fuels , or if they are produced from waste carbon or seawater carbonic acid , and their combustion is subject to carbon capture at the flue or exhaust pipe , they result in negative carbon dioxide emission and net carbon dioxide removal from the atmosphere , and thus constitute a form of greenhouse gas remediation . Such power to gas carbon-neutral and carbon-negative fuels can be produced by the electrolysis of water to make hydrogen used in the Sabatier reaction to produce methane which may then be stored to be burned later in power plants as synthetic natural gas , transported by pipeline , truck , or tanker ship , or be used in gas to liquids processes such as the Fischer -- Tropsch process to make traditional fuels for transportation or heating . Carbon-neutral fuels are used in Germany and Iceland for distributed storage of renewable energy , minimizing problems of wind and solar intermittency , and enabling transmission of wind , water , and solar power through existing natural gas pipelines . Such renewable fuels could alleviate the costs and dependency issues of imported fossil fuels without requiring either electrification of the vehicle fleet or conversion to hydrogen or other fuels , enabling continued compatible and affordable vehicles .

The carbon neutrality concept may be extended to include other greenhouse gases ( GHG ) measured in terms of their carbon dioxide equivalence ( e ) -- the impact a GHG has on the atmosphere expressed in the equivalent amount of CO2 . The term `` climate neutral '' reflects the broader inclusiveness of other greenhouse gases in climate change , even if CO2 is the most abundant , encompassing other greenhouse gases regulated by the Kyoto Protocol , namely : methane ( CH4 ) , nitrous oxide ( N2O ) , hydrofluorocarbons ( HFC ) , perfluorocarbons ( PFC ) , and sulphur hexafluoride ( SF6 ) . Both terms are used interchangeably throughout this article . The best practice for organizations and individuals seeking carbon neutral status entails reducing and/or avoiding carbon emissions first so that only unavoidable emissions are offset . Carbon neutral status is commonly achieved in two ways : Balancing carbon dioxide released into the atmosphere from burning fossil fuels , with renewable energy that creates a similar amount of useful energy , so that the carbon emissions are compensated , or alternatively using only renewable energies that do n't produce any carbon dioxide ( also called a post-carbon economy ) . Carbon offsetting by paying others to remove or sequester 100 % of the carbon dioxide emitted from the atmosphere -- for example by planting trees -- or by funding ` carbon projects ' that should lead to the prevention of future greenhouse gas emissions , or by buying carbon credits to remove ( or ` retire ' ) them through carbon trading . While carbon offsetting is often used alongside energy conservation measures to minimize energy use , the practice is criticized by some .

Carbon tax offers social and economic benefits . It is a tax that increases revenue without significantly altering the economy while simultaneously promoting objectives of climate change policy . The objective of a carbon tax is to reduce the harmful and unfavorable levels of carbon dioxide emissions , thereby decelerating climate change and its negative effects on the environment and human health .

Carbon offsets are measured in metric tons of carbon dioxide-equivalent ( CO2e ) and may represent six primary categories of greenhouse gases : carbon dioxide , methane ( CH4 ) , nitrous oxide ( N2O ) , perfluorocarbons ( PFCs ) , hydrofluorocarbons ( HFCs ) , and sulfur hexafluoride ( SF6 ) . One carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases . There are two markets for carbon offsets . In the larger , compliance market , companies , governments , or other entities buy carbon offsets in order to comply with caps on the total amount of carbon dioxide they are allowed to emit . This market exists in order to achieve compliance with obligations of Annex 1 Parties under the Kyoto Protocol , and of liable entities under the EU Emission Trading Scheme . In 2006 , about $ 5.5 billion of carbon offsets were purchased in the compliance market , representing about 1.6 billion metric tons of CO2e reductions . In the much smaller , voluntary market , individuals , companies , or governments purchase carbon offsets to mitigate their own greenhouse gas emissions from transportation , electricity use , and other sources . For example , an individual might purchase carbon offsets to compensate for the greenhouse gas emissions caused by personal air travel . Many companies ( see list ) offer carbon offsets as an up-sell during the sales process so that customers can mitigate the emissions related with their product or service purchase ( such as offsetting emissions related to a vacation flight , car rental , hotel stay , consumer good , etc. ) . In 2008 , about $ 705 million of carbon offsets were purchased in the voluntary market , representing about 123.4 million metric tons of CO2e reductions . Some fuel suppliers in the UK offer fuel which has been carbon offset such as Fuel dyes . Offsets are typically achieved through financial support of projects that reduce the emission of greenhouse gases in the short - or long-term . The most common project type is renewable energy , such as wind farms , biomass energy , or hydroelectric dams . Others include energy efficiency projects , the destruction of industrial pollutants or agricultural byproducts , destruction of landfill methane , and forestry projects . Some of the most popular carbon offset projects from a corporate perspective are energy efficiency and wind turbine projects . Carbon offsetting has gained some appeal and momentum mainly among consumers in western countries who have become aware and concerned about the potentially negative environmental effects of energy-intensive lifestyles and economies . The Kyoto Protocol has sanctioned offsets as a way for governments and private companies to earn carbon credits that can be traded on a marketplace . The protocol established the Clean Development Mechanism ( CDM ) , which validates and measures projects to ensure they produce authentic benefits and are genuinely `` additional '' activities that would not otherwise have been undertaken . Organizations that are unable to meet their emissions quota can offset their emissions by buying CDM-approved Certified Emissions Reductions . Emissions from burning fuel , such as red diesel , has pushed one UK fuel supplier to create a carbon offset fuel named Carbon Offset Red Diesel . Offsets may be cheaper or more convenient alternatives to reducing one 's own fossil-fuel consumption . However , some critics object to carbon offsets , and question the benefits of certain types of offsets . Due diligence is recommended to help businesses in the assessment and identification of `` good quality '' offsets to ensure offsetting provides the desired additional environmental benefits , and to avoid reputational risk associated with poor quality offsets . Offsets are viewed as an important policy tool to maintain stable economies and to improve sustainability . One of the hidden dangers of climate change policy is unequal prices of carbon in the economy , which can cause economic collateral damage if production flows to regions or industries that have a lower price of carbon -- unless carbon can be purchased from that area , which offsets effectively permit , equalizing the price .", "qid": "656", "docid": "Carbon_offset", "rank": 46, "score": 113320 }, { "content": "Title: Emission Reduction Unit Content: The emission reduction unit ( ERU ) is an emissions unit issued under a Joint Implementation project in terms of the Kyoto Protocol .

In the realm of carbon-hydrogen bond activation and functionalization ( C-H activation/functionalization ) , many recent efforts have been made in order to catalytically functionalize the C-H bonds in methane . The large abundance of methane in natural gas or shale gas deposits presents a large potential for its use as a feedstock in modern chemistry . However , given its gaseous natural state , it is quite difficult to transport economically . Its ideal use would be as a raw starting material for methanol or acetic acid synthesis , with plants built at the source to eliminate the issue of transportation . Methanol , in particular , would be of great use as a potential fuel source , and many efforts have been applied to researching the feasibilities of a methanol economy . The challenges of C-H activation and functionalization present themselves when several factors are taken into consideration . Firstly , the C-H bond is extremely inert and non-polar , with a high bond dissociation energy , making methane a relatively unreactive starting material . Secondly , any products formed from methane would likely be more reactive than the starting product , which would be detrimental to the selectivity and yield of the reaction . The main strategy currently used to increase the reactivity of methane uses transition metal complexes to activate the carbon-hydrogen bonds . In a typical C-H activation mechanism , a transition metal catalyst coordinates to the C-H bond to cleave it , and convert it into a bond with a lower bond dissociation energy . By doing so , the product can be used in further downstream reactions , since it will usually have a new functional group attached to the carbon . It is also important to note the difference between the terms `` activation '' and `` functionalization , '' since both terms are often used interchangeably , but should be held distinct from each other .

A number of factors make this a difficult problem from both economic and political perspectives : it is a long-term , intergenerational problem ; benefits and costs are distributed unequally both within and across countries ; and scientific and public opinions may diverge . One of the most important greenhouse gases is carbon dioxide . Around 20 % of carbon dioxide which is emitted due to human activities can remain in the atmosphere for many thousands of years . The long time scales and uncertainty associated with global warming have led analysts to develop `` scenarios '' of future environmental , social and economic changes . These scenarios can help governments understand the potential consequences of their decisions . The impacts of climate change include the loss of biodiversity , sea level rise , increased frequency and severity of some extreme weather events , and acidification of the oceans . Economists have attempted to quantify these impacts in monetary terms , but these assessments can be controversial . The two main policy responses to global warming are to reduce greenhouse gas emissions ( climate change mitigation ) and to adapt to the impacts of global warming ( e.g. , by building levees in response to sea level rise ) . Another policy response which has recently received greater attention is geoengineering of the climate system ( e.g. injecting aerosols into the atmosphere to reflect sunlight away from the Earth 's surface ) . One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making . This strategy recognizes that decisions on global warming need to be made with incomplete information , and that decisions in the near term will have potentially long-term impacts . Governments might choose to use risk management as part of their policy response to global warming . For instance , a risk-based approach can be applied to climate impacts which are difficult to quantify in economic terms , e.g. , the impacts of global warming on indigenous peoples . Analysts have assessed global warming in relation to sustainable development . Sustainable development considers how future generations might be affected by the actions of the current generation . In some areas , policies designed to address global warming may contribute positively towards other development objectives . In other areas , the cost of global warming policies may divert resources away from other socially and environmentally beneficial investments ( the opportunity costs of climate change policy ) .", "qid": "656", "docid": "Economics_of_global_warming", "rank": 58, "score": 109424 }, { "content": "Title: Climate change in the United States Content: Because of global warming , there has been concern in the United States and internationally , that the country should reduce total greenhouse gas which is relatively high per capita .

As well as the economic cost of lost commodities , fugitive emissions contribute to air pollution and climate change . A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide , or 12 per cent of all greenhouse gases emitted by the sector . Venting of natural gas , flaring , accidental releases and storage losses accounted for an additional 38 per cent . Fugitive emissions present other risks and hazards . Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities . In situations where large amounts of flammable liquids and gases are contained under pressure , leaks also increase the risk of fire and explosion . Leaks from pressurized process equipment generally occur through valves , pipe connections , mechanical seals , or related equipment . Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks . Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks , fugitive emissions can be a significant proportion of total emissions . Though the quantities of leaked gases may be small , gases that have serious health or environmental impacts can cause a significant problem . To minimize and control leaks at process facilities operators carry out regular leak detection and repair activities . Routine inspections of process equipment with gas detectors can be used to identify leaks and estimate the leak rate in order to decide on appropriate corrective action . Proper routine maintenance of equipment reduces the likelihood of leaks . Because of the technical difficulties and costs of detecting and quantifying actual fugitive emissions at a site or facility , and the variability and intermittent nature of emission flow rates , bottom-up estimates based on standard emission factors are generally used for annual reporting purposes . New technologies are under development that could revolutionize the detection and monitoring of fugitive emissions . One technology , known as differential absorption lidar ( DIAL ) , can be used to remotely measure concentration profiles of hydrocarbons in the atmosphere up to several hundred meters from a facility . DIAL has been used for refinery surveys in Europe for over 15 years . A pilot study carried out in 2005 using DIAL found that actual emissions at a refinery were fifteen times higher than those previously reported using the emission factor approach . The fugitive emissions were equivalent to 0.17 % of the refinery throughput . Portable gas leak imaging cameras are also a new technology that can be used to improve leak detection and repair , leading to reduced fugitive emissions .

As a consequence , high paleolatitudes in both hemispheres were much warmer than at present . This temperature gradient was partly responsible for the lack of continental ice sheets in polar regions . As a response to elevated global temperatures , the Earth 's hydrologic cycle was significantly enhanced due to greater volume of moisture evaporation from the surface of the ocean . In turn , the absolute sea level during this time period stood at elevations much higher than the present level . Continental encroachment of seawater formed widespread shallow seas , including expanses of epeiric seas . An increase in surface area between shallow , warm epeiric seawater and the atmosphere permits higher evaporation rates and more precipitation at various latitudes , producing a more temperate global climate .

Second , if the North Atlantic drift were to shut down , that barrier would fail , releasing a flood of frozen air into the Northern Hemisphere , causing a sudden and drastic temperature shift . The book discusses a possible cause of the failure of the Gulf Stream : the melting of the polar ice caps could drastically affect the salinity of the North Atlantic drift by dumping a large quantity of freshwater into the world 's oceans .

Materials that exist primarily in the gas phase at STP are referred to as `` volatile . '' Many natural and man-made ( anthropogenic ) materials are stable in two states at STP , earning them the title `` semi-volatile . '' A naturally occurring volatile that is sometimes found in aqueous solution is methane , water itself is semi-volatile . Man-made or anthropogenic chemicals also occur in these classes . Examples of volatile anthropogenic chemicals include the refrigerants chlorofluorocarbons ( CFCs ) and hydrofluorocarbons ( HCFCs ) . Semivolatile anthropogenics can exist as mixtures , such as petroleum distillates or as pure chemicals like trichloroethylene ( TCE ) . There is a need to analyze the dissolved gas content of aqueous solutions . Dissolved gases can directly interact with aquatic organisms or can volatilize from solution ( the latter described by Henry 's Law ) . These processes can result in exposure that , depending on the nature of the dissolved material , can have negative health effects . There is natural occurrence of various dissolved gases in groundwater and can be a measure of health for lakes , streams and rivers . Dissolved gases also occur as a result of human contamination from fuel and chlorinated spill sites . This method can be used to determine if there is natural biodegradation processes occurring in contaminated aquifers . For example , fuel hydrocarbons will break down into methane . Chlorinated solvents such as trichloroethylene , break down into ethene and chloride . Detecting these compounds can determine if biodegradation processes are occurring and possibly at what rate . Natural gas extracted from the earth also contains many low molecular weight hydrocarbon compounds such as methane , ethane , propane and butane . For example , methane has been found in many water wells in West Virginia . Chromatographic techniques are often useful when mixtures of analytes are present because they are capable of measuring multiple analytes during a single application . They require isolation of the analyte from the matrix they come in ( the body of the sample ) . One of the simpler techniques is to simply trap the analytes in a bubble of air above the sample ( headspace ) and inject part of that bubble directly into the instrument . This procedure is called headspace analysis . One of the most widely used methods for headspace analysis is described by the United States Environmental Protection Agency ( USEPA ) and is called RSKSOP-175 . This method is described below .", "qid": "656", "docid": "Headspace_Gas_Chromatography_for_Dissolved_Gas_Measurement", "rank": 80, "score": 102881 }, { "content": "Title: Low-carbon emission Content: The main components of automobile exhaust are carbon dioxide ( CO2 ) and water vapor ( H2O ) .

Tegart , G.W. Sheldon and D.C. Griffiths Working Group III : The IPCC Response Strategies Each section included a summary for policymakers . This format was followed in subsequent Assessment Reports . The executive summary of the policymakers ' summary of the WG I report includes : We are certain of the following : there is a natural greenhouse effect ... ; emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases : CO2 , methane , CFCs and nitrous oxide . These increases will enhance the greenhouse effect , resulting on average in an additional warming of the Earth 's surface . The main greenhouse gas , water vapour , will increase in response to global warming and further enhance it . We calculate with confidence that : ... CO2 has been responsible for over half the enhanced greenhouse effect ; long-lived gases would require immediate reductions in emissions from human activities of over 60 % to stabilise their concentrations at today 's levels ... Based on current models , we predict : under -LSB- BAU -RSB- increase of global mean temperature during the -LSB- 21st -RSB- century of about 0.3 oC per decade ( with an uncertainty range of 0.2 to 0.5 oC per decade ) ; this is greater than that seen over the past 10,000 years ; under other ... scenarios which assume progressively increasing levels of controls , rates of increase in global mean temperature of about 0.2 oC -LSB- to -RSB- about 0.1 oC per decade . There are many uncertainties in our predictions particularly with regard to the timing , magnitude and regional patterns of climate change , due to our incomplete understanding of : sources and sinks of GHGs ; clouds ; oceans ; polar ice sheets . Our judgement is that : global mean surface air temperature has increased by 0.3 to 0.6 oC over the last 100 years ... ; The size of this warming is broadly consistent with predictions of climate models , but it is also of the same magnitude as natural climate variability . Thus the observed increase could be largely due to this natural variability ; alternatively this variability and other human factors could have offset a still larger human-induced greenhouse warming . The unequivocal detection of the enhanced greenhouse effect is not likely for a decade or more . under the IPCC business as usual emissions scenario , an average rate of global mean sea level rise of about 6 cm per decade over the next century ( with an uncertainty range of 3 -- 10 cm per decade ) , mainly due to thermal expansion of the oceans and the melting of some land ice .

Carbon-based fuels are of two main kinds , biofuels and fossil fuels . Whereas biofuels are derived from recent-growth organic matter and are typically harvested , as with logging of forests and cutting of corn , fossil fuels are of prehistoric origin and are extracted from the ground , the principal fossil fuels being oil , coal , and natural gas . From an economic policy perspective , an important distinction between biofuels and fossil fuels is that only the former is sustainable or renewable . Whereas we can continue to obtain energy from biofuels indefinitely in principle , the Earth 's reserves of fossil fuels was determined millions of years ago and is therefore fixed as far as our foreseeable future is concerned . The great variability in the ease of extraction of fossil fuels however makes its endgame scenario one of increasing prices over one or more centuries rather than of abrupt exhaustion . From the perspective of climate and ecology , biofuels and fossil fuels have in common that they contribute to the production of atmospheric carbon dioxide , which has emerged in recent decades as the fastest-changing greenhouse gas , whose principal impacts are global warming and ocean acidification . However biofuels actively participate in the carbon cycle today by photosynthesizing carbon dioxide , unlike fossil fuels whose participation was long ago , and can therefore in principle bring atmospheric CO2 into an equilibrium not possible with the continued use of fossil fuel . But in practice photosynthesis is a slow process , and the additional fuel produced by artificial methods of accelerating it such as application of fertilizer tends to be offset by the energy consumed by the accelerating processes , to a degree currently under active debate . In contrast the speed of photosynthesis is immaterial for fossil fuels because they had millions of years in which to accumulate .

During a pole 's winter , it lies in continuous darkness , chilling the surface and causing the deposition of 25 -- 30 % of the atmosphere into slabs of CO2 ice ( dry ice ) . When the poles are again exposed to sunlight , the frozen CO2 sublimes , creating enormous winds that sweep off the poles as fast as 400 km/h . These seasonal actions transport large amounts of dust and water vapor , giving rise to Earth-like frost and large cirrus clouds . Clouds of water-ice were photographed by the Opportunity rover in 2004 . The caps at both poles consist primarily of water ice . Frozen carbon dioxide accumulates as a comparatively thin layer about one metre thick on the north cap in the northern winter only , while the south cap has a permanent dry ice cover about 8 m thick . The northern polar cap has a diameter of about 1000 km during the northern Mars summer , and contains about 1.6 million cubic km of ice , which if spread evenly on the cap would be 2 km thick . ( This compares to a volume of 2.85 million cubic km ( km3 ) for the Greenland ice sheet . ) The southern polar cap has a diameter of 350 km and a thickness of 3 km . The total volume of ice in the south polar cap plus the adjacent layered deposits has also been estimated at 1.6 million cubic km . Both polar caps show spiral troughs , which recent analysis of SHARAD ice penetrating radar has shown are a result of roughly perpendicular katabatic winds that spiral due to the Coriolis Effect . The seasonal frosting of some areas near the southern ice cap results in the formation of transparent 1 m thick slabs of dry ice above the ground . With the arrival of spring , sunlight warms the subsurface and pressure from subliming CO2 builds up under a slab , elevating and ultimately rupturing it . This leads to geyser-like eruptions of CO2 gas mixed with dark basaltic sand or dust . This process is rapid , observed happening in the space of a few days , weeks or months , a rate of change rather unusual in geology -- especially for Mars . The gas rushing underneath a slab to the site of a geyser carves a spider-like pattern of radial channels under the ice .", "qid": "661", "docid": "Martian_polar_ice_caps", "rank": 34, "score": 114526 }, { "content": "Title: HMS Protector (A173) Content: HMS Protector is a Royal Navy ice patrol ship built in Norway in 2001 .

As the demographic transition follows its course worldwide , the population will age significantly , with most countries outside Africa trending towards a rectangular age pyramid . According to the 2015 edition of the United Nations ' World Population Prospects report , the world population is currently growing by approximately 83 million people each year . The growth rate keeps slowing , having decreased from 1.55 % per year in 1995 to 1.25 % in 2005 and 1.18 % in 2015 . The median estimate for future growth sees the world population reaching 9.7 billion in 2050 and 11.2 billion in 2100 , assuming a continuing decrease in average fertility rate from 2.5 in 2015 to 2.25 in 2050 and 2.0 in 2100 . With longevity trending towards uniform and stable values worldwide , the main driver of future population growth is the evolution of the fertility rate . While most scenarios still predict continued growth into the 22nd century , there is a roughly 23 % chance that the total population could stabilize or begin to fall before 2100 . Longer-term speculative scenarios over the next two centuries can predict anything between runaway growth to radical decline ( 36.4 billion or 2.3 billion people in 2300 ) , with the median projection showing a slight decrease followed by a stabilization around 9 billion people . By 2050 , the bulk of the world 's population growth will take place in Africa : of the additional 2.4 billion people projected between 2015 and 2050 , 1.3 billion will be added in Africa , 0.9 billion in Asia and only 0.2 billion in the rest of the world .

As a consequence , high paleolatitudes in both hemispheres were much warmer than at present . This temperature gradient was partly responsible for the lack of continental ice sheets in polar regions .

It is best known for its very slow rate of development . It was once estimated that it had a 14-year lifecycle from egg to adult moth , unique among the Lepidoptera with the ability to withstand temperatures below − 60 ° C . The larvae degrade their mitochondria in preparation for overwintering and resynthesize them in the spring , and each instar of the caterpillar takes about a year . Subsequent studies have revised the lifecycle duration to be 7 years . The Arctic woolly bear caterpillars are unique in their combination of adaptations to the polar extremes . They spend nearly 90 % of their lives frozen and only about 5 % feeding on the tundra during June ; the remainder is spent in summer aestivation within hibernacula ( protective cocoons ) . Hiding within hibernacula serves several functions : protection from insect parasitoids that kill about 75 % of the larvae and pupae , avoidance of secondary metabolites built up in their food source , the Arctic willow , degradation of mitochondria linked to hypometabolism and antifreeze synthesis , and conservation of energy reserves needed to synthesize cryoprotective compounds required for freezing survival . Two insect parasitoids attack woolly bear moth caterpillars : an ichneumonid wasp ( reported as Hyposoter pectinatus but probably Hyposoter deichmanni ) and a tachinid fly ( Exorista thula ) . The wasp , a solitary parasitoid , kills about 20 % of the third and fourth instars of the host while the gregarious bristle fly causes about 50 % mortality in the instar 5 and 6 , and pupae . The extreme winter temperatures are not as detrimental to Gynaephora caterpillars as are the parasitoids . The larvae are extremely freeze-tolerant , able to survive temperatures down to -70 ° C . As temperatures decrease during the late arctic summer , the larvae start synthesizing cryoprotective compounds , such as glycerol , in addition to some unusual ones , e.g. betaine . Accumulation of these `` antifreezes `` is aided by bottle-necking of oxidative phosphorylation through mitochondrial degradation . The woolly bears resynthesize the mitochondria the following spring upon resumption of their activity .
