Global Temperatures To Rise At Least 4°C By 2100

Global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions are not reduced according to new research published in Nature. Scientists found global climate is more sensitive to carbon dioxide than most previous estimates.The research also appears to solve one of the great unknowns of climate sensitivity, the role of cloud formation and whether this will have a positive or negative effect on global warming.Prof Steve Sherwood explains research into cloud mixing that indicates our climate is highly sensitive to a doubling of carbon dioxide. His findings suggest Equilibrium Climate Sensitivity is at least 3°C. As a result, unless we curb emissions, global temperatures will rise 4°C by 2100 and more than 8°C by 2200.
