22 Greenhouse Gas Climate Models v. Actual Satellite Observations

Read the 2008 paper here. From the abstract: "model results and temperature trends are in disagreement in most of the tropical troposphere, being separated by more than twice the uncertainty of the model mean. " & "modelled and observed trends have opposite signs" & "These conclusions contrast strongly with those of recent publications based on essentially the same data" and in the Conclusions:

The difference in CO2 sensitivity between satellite observations and the models is a factor of about 3!
