Scientists Believe Current Models Do Not Accurately Represent the Sensitivity of Global Temperatures to CO2
…from The Telegraph…
“The scientists compared temperature reconstructions from sediments in the ocean floor with a global climate simulation model which aimed to map climate three million years ago.
“Study leader Dr Dan Lunt, from the University of Bristol, said: “We found that, given the concentrations of carbon dioxide prevailing three million years ago, the model originally predicted a significantly smaller temperature increase than that indicated by the reconstructions. This led us to review what was missing from the model.”
“They believe current models do not accurately represent the sensitivity of global temperatures to CO2.
“Climate models used by bodies such as the Intergovernmental Panel on Climate Change often fail to take full account of such effects, said the researchers, whose findings are reported in the journal Nature Geoscience.”
