Richard Lindzen is an atmospheric physicist, Emeritus Professor at MIT. From 1983 until his retirement in 2013 he was Alfred P. Sloan Professor of Meteorology at MIT: Here are two statements that are completely agreed on by the IPCC. It is crucial to be aware of their implications. 1. A doubling of CO2, by itself, contributes only about 1C to greenhouse warming. 2. If one assumes all warming over the past century is due to anthropogenic greenhouse forcing, then the derived sensitivity of the climate to a doubling of CO2 is less than 1C. The notion that alarming warming is ‘settled science’ should be offensive to any sentient individual, though to be sure, the above is hardly emphasized by the IPCC.
