A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.
As carbon dioxide accumulates in the atmosphere, the Earth will get hotter. But exactly how much warming will result from a certain increase in CO2 is under study. The relationship between CO2 and warming, known as climate sensitivity, determines wha
The Arctic is very sensitive to climate change. In the last 40 years, the region has warmed much more rapidly than the Earth as a whole, a new study finds.
The Arctic is heating up nearly four times faster than the whole planet, study finds
