Does basic physics lead to the unavoidable conclusion that we must be concerned about global warming?
The CHUO blog article about the interview is HERE. The MP3 of the interview can be downloaded HERE.
In this lively radio debate, Pierrehumbert compared the certainty of climate physics predictions in complex global circulation models to the certainty of the theory of gravitation, no less. He also advanced that physicists (e.g., Rancourt) who don't agree that global warming is of significant concern for the environment and humanity are physicists who don't understand physics.
Pierrehumbert also had "kind words" about Richard Lindzen of MIT.
