Consensus on Hurricanes and Global Warming

“[T]here is no sound theoretical basis for drawing any conclusions about how anthropogenic change affects hurricane numbers or tracks, and thus how many hit land.” K. Trenberth, Science, 17 June 2005
Last winter, Chris Landsea caused a flap when he resigned from the IPCC claiming that Kevin Trenberth, the lead author of the IPCC chapter that he was contributing to, had made unfounded statements about hurricanes and global warming in a press conference organized by Harvard to allege a connection between the U.S. hurricane damages of 2004 and human-caused climate change. (Disclaimer: As most regular readers know, Landsea is a long-time collaborator of mine.) In this week’s Science, Trenberth has an essay on hurricanes and climate change that should put this issue to rest. Trenberth’s essay clearly vindicates Landsea’s actions, and, in my opinion, it would not be inappropriate for IPCC officials who failed to support Landsea (Rajedra Pachauri and Susan Solomon) to issue him a public apology. But don’t hold your breath.
Let’s take a quick look at Trenberth’s essay and explain why it vindicates Landsea.
