This article by Rupert Darwall is a review of Steven Koonin’s new book. Koonin is a physicist at New York University. He was the lead moderator of a debate hosted by the American Physical Society (APS) between three climate scientists who agreed and three who disagreed with the IPCC’s position on climate change. The climate skeptics easily won the debate. Koonin wrote “I came away from the APS workshop not only surprised, but shaken by the realization that climate science was far less mature than I had supposed.” The IPCC is not telling the whole truth. Koonin’s indictment of the IPCC science starts with its reliance on unreliable computer models. The modeler admitted to tuning their model by targeting an equilibrium climate sensitivity of about 3 C, the value the IPCC wants. Koonin wrote “That the models can’t reproduce the past is a big red flag – it erodes confidence in their projections of future climates.” Darwall wrote in his review “The second part of Koonin’s indictment concerns the distortion, misrepresentation, and mischaracterization of climate data to support a narrative of climate catastrophism based on increasing frequency of extreme weather events.”
