There is debate over whether the cause is global warming

"Allstate Corp., one of Maryland's largest insurers, will stop writing homeowners' policies in coastal areas of the state, citing warnings by scientists that a warmer Atlantic Ocean will lead to more strong hurricanes hitting the Northeast.

Allstate also decided recently to let thousands of homeowner policies lapse in the Carolinas, New York and Texas, and to no longer write new policies in parts of Virginia and all of Connecticut, Delaware and New Jersey.

There is debate over whether the cause is global warming or a natural warming cycle. The National Association of Insurance Commissioners set up a task force to study climate change."
