That's a nice *blog* post and something everyone should keep in mind. But the real debate isn't about whether or not these storms are unprecedented, because they're not (there have been more powerful storms than Katrina in the last 20 years obviously), but the frequency of such storms. And like he said the expansion of people in vulnerable areas hasn't helped things any but you can be hit by a hurricane in some form anywhere in this country. Do you seriously think we should just move millions of people off the coast? That would A) be an almost impossible task and B) Devastating and not very feasible on so many levels! Think about transportation, commerce, current infrastructure, national defense the list goes on and on. Yes we should discourage people from rebuilding in the most vulnerable areas, but to deny people recovery assistance would be ludicrous.
