Levitt recently discussed the SuperFreakonomics chapter about global warming on NPR’s Weekend Edition. Blog posts about the controversy generated by that chapter are collected here. SuperFreakonomics is well into its second month on The N.Y. Times best-seller list and remains the nation’s best-selling business book, as ranked by both the Wall Street Journal and New York Times. Meanwhile, Freakonomics has been named one of the best books of the decade by The Onion’s A.V. Club, the Times (U.K.), and the Telegraph.
