evidences.evidence: "The overall risks of climate change impacts can be reduced by limiting the rate and magnitude of climate change" Without new policies to mitigate climate change, projections suggest an increase in global mean temperature in 2100 of 3.7 to 4.8 °C, relative to pre-industrial levels (median values; the range is 2.5 to 7.8 °C including climate uncertainty).
