"University of Michigan researchers have done the unthinkable, and checked climate model predictions against available paleo-climate data to see if the predictions are plausible.
A new study from University of Michigan climate researchers concludes that some of the latest-generation climate models may be overly sensitive to carbon dioxide increases and therefore project future warming that is unrealistically high.
...“Our study implies that CESM2’s climate sensitivity of 5.3 C is likely too high.
This means that its prediction of future warming under a high-CO2 scenario would be too high as well,” said Zhu, first author of the Nature Climate Change letter.
