The effect of global warming on homeownership

I was reading an interesting Newsweek article this morning (http://www.msnbc.msn.com/id/16720746/site/newsweek/). It talked about how insurance companies are raising rates and even canceling homeowner insurance policies all across the eastern seaboard. The insurance companies say that in recent years there have been many more extreme weather catastrophes -- hurricanes, ice storms, lightning strikes -- than there were in the past. Ignoring the controversy over whether these weather changes are a result of global warming, the important thing to point out is that future home buyers will probably be increasingly concerned with things like the cost of homeowner's insurance and how well the home can survive weather-related disasters. I know that if I were buying a home in certain areas today I'd want to know what features it had to better survive hurricanes and windstorms. This seems like a trend that has been largely ignored and, if you believe in global warming, will only get more pronounced in coming years. If anyone out there is hearing these concerns from prospective buyers (or sellers who have to move because it's gotten too expensive to live where they are), I'd love to hear about it.
