Now, the scientific community is warning us that the average hurricane will continue to get stronger because of global warming. A scientist at MIT has published a study well before this tragedy showing that since the 1970s, hurricanes in both the Atlantic and the Pacific have increased in duration, and in intensity, by about 50 %. The newscasters told us after Hurricane Katrina went over the southern tip of Florida that there was a particular danger for the Gulf Coast of the hurricanes becoming much stronger because it was passing over unusually warm waters in the gulf. The waters in the gulf have been unusually warm. The oceans generally have been getting warmer. And the pattern is exactly consistent with what scientists have predicted for twenty years. Two thousand scientists, in a hundred countries, engaged in the most elaborate, well organized scientific collaboration in the history of humankind, have produced long-since a consensus that we will face a string of terrible catastrophes unless we act to prepare ourselves and deal with the underlying causes of global warming.Hurricanes over the years:

If this seems like old news, that's because it is. As WaPo columnist Joel Achenbach says, "[s]omewhere along the line, global warming became the explanation for everything."
Still, there's a silver lining among the storm clouds: although the web site for Gore's film still includes the hurricane claim, Anthony Watts reports that "Al Gore has dropped the [hurricane frequency] related slide in his traveling PowerPoint show."
Facts are stubborn things--so count me with Watts commenter Steve Sadlov:
I just figured it out. Hurricane frequency is a leading economic indicator!Suggesting again that finance and climate change share at least one trait: their computer models are way off. Warming, if it exists, isn't driving hurricanes.
