claim: While evidence that the earth’s orbital variations impact radiation levels and thus global temperatures does not of course mean that man is not in some way impacting the climate, studies like these highlight that the role man plays on the planet is dwarfed by natural phenomena utterly out of our control.

evidences.evidence: There are many interesting palaeoclimate studies that suggest that solar variability had an influence on pre-industrial climate.

evidences.evidence: The consensus is that several factors are important: atmospheric composition, such as the concentrations of carbon dioxide and methane (the specific levels of the previously mentioned gases are now able to be seen with the new ice core samples from EPICA Dome C in Antarctica over the past 800,000 years); changes in the earth's orbit around the Sun known as Milankovitch cycles; the motion of tectonic plates resulting in changes in the relative location and amount of continental and oceanic crust on the earth's surface, which affect wind and ocean currents; variations in solar output; the orbital dynamics of the Earth–Moon system; the impact of relatively large meteorites and volcanism including eruptions of supervolcanoes.

evidences.evidence: Physical evidence shows that the variation in Earth's climate is much more extreme than the variation in the intensity of solar radiation calculated as the Earth's orbit evolves.

evidences.evidence: Since orbital variations are predictable, any model that relates orbital variations to climate can be run forward to predict future climate, with two caveats: the mechanism by which orbital forcing influences climate is not definitive; and non-orbital effects can be important (for example, Human impact on the environment principally increases in greenhouse gases result in a warmer climate).
