Are Scientists Underestimating Earth's Sensitivity To CO2?

A study appearing in Nature Geoscience this week claims that Earth's temperature may be 30-50% more sensitive to atmospheric carbon dioxide than previous estimates suggest, and the effects of this increased sensitivity could make climate change an even bigger threat than it already is. The results of the study show that the models currently used to forecast climate change often neglect components of the Earth's climate system that vary over long timescales and have an important effect on temperature sensitivity--such as land-ice and vegetation. read more
