A recent Wall Street Journal article critiques insurers for the recent use of computerized risk projection models to take global warming into account.  Previously, insurers relied primarily on historical data to set rates.  After the severe hurricanes in 2004, insurers started using new computer models to project natural catastrophes over the next several years (a relatively short window with a fair amount of uncertainty built in).  The article notes that rates have gone up 20% to 100% since 2004.  As a result, people can no longer afford insurance and are starting to sell their coastline properties.

This issue is particularly relevant to Hawaii, where a significant number of residential properties could be defined as coastline.  Is anyone aware of statistics documenting this trend?
