I've heard some speculation that global warming is the cause of the recent upswing in the number of major hurricane hits to the US. Apparently that's not the case. However, as common sense would suggest, it is possible that global warming will affect hurricane season in some way, and a recent article in Nature suggests that it already has, in that total power has increased over the last 30 years - but nevertheless the current/recent Atlantic activity, they say, is no more than one would expect from normal variation.

Further reading on hurricanes and on global warming in general for the curious (I'm looking at you, [livejournal.com profile] upsilon! :) ). Some of them are pretty old at this point, but I tried to pick things in reputable journals.

Knutson TR, Tuleya RE, & Kurihara Y. (1998). "Simulated increase of hurricane intensities in a CO2-warmed climate." Science, 279: 1018-1020.
Harman JR, Harrington JA, & Cerveny RS. (1998). "Science, policy, and ethics: Balancing scientific and ethical values in environmental science." Annals of the Association of American Geographers, 88(2): 277-286. (This is a really great article!)
Nordhaus WD. (1993). "Reflections on the economics of climate change." Journal of Economic Perspectives, 7(4): 11-25.

Time to get my mind off the climate change train and on the getting to school on time train.

"Great idea in theory, except that this prevents the floods from depositing more silt, so the land that the city is built upon just sinks instead of getting new earth to be on top of."

Thanks for the explanation. I had been entirely missing that point, and wondering how it was even possible to build a city below sea level in the first place.... Looking at as a city that has sunk since it was built, suddenly it all makes sense.

Plus there's the joy of coastal erosion -- when the floods don't deposit fresh earth, the waters of the Gulf are free to eat away at the land... which of course diminishes the natural barrier between the sea and the city.
