Nobel Laureate economist Gary Becker and polymath Judge Richard Posner comment on climate change policy on The Becker-Posner Blog. In short, Judge Posner supports Kyoto due to the risk of catastrophic climate change, Becker does not. While Becker agrees that "it is prudent to take actions to reduce the build-up of carbon gases in the atmosphere," he is skeptical about many government policies, including subsidies for less carbon-intensive fuels, and suggests that Judge Posner's own work on catastrophic risks suggests that climatic change may be the least of our worries.
