Gerard Baker writes in TimeOnline.co.uk, "the intellectual looters have busied themselves with plundering half-truths and false analyses to advance one of their most precious agendas: global warming."
Before you get upset, go read the piece. It isn't factually incorrect. People are coming out of the woodwork to say that Katrina is a product of global warming. Of course, it is not, at least not directly. Even in my post earlier, I didn't really mention that. We've been down this road before. There isn't much theoretical or observational evidence that the frequency of tropical cyclones increases with global warming, but there is evidence that they become more intense. Katrina is not really an extraordinary storm; there have been lots of big, intense hurricanes in the past. I think it is likely that links between cyclone frequency and global warming will emerge eventually, probably just through a longer cyclone season... i.e., a longer time of optimal conditions for cyclogenesis will probably spawn more cyclones. It's also likely that stronger cyclones (as discussed here before, including discussion of Kerry Emanuel's recent study) will mean more named storms, and lay-people will interpret that as "more" cyclones when really they are just more intense.
Gerard Baker goes one to rip Bush a new one too. He chastises the US federal government for flubbing this disaster relief so far. I won't comment here, but I'll bet you can guess where I fall on the issue... you'd be pretty close.
