New international analysis narrows the range in sensitivity of climate to CO2
Lawrence Livermore National LaboratoryThe most advanced and comprehensive analysis of climate sensitivity undertaken has revealed with more confidence than ever how sensitive the Earth’s climate is to carbon dioxide. This new research finds that the true climate sensitivity is unlikely to be in the lowest part of the 2.7-8.1˚F range. The analysis indicates that if atmospheric carbon dioxide levels double from their pre-industrial levels and are maintained, the world would be likely to experience eventual warming from 4.1-8.1˚F. There would be less than 5 percent chance of staying below 3.6˚F and a 6-18 percent chance of exceeding 8.1˚F.
