Oh, just this, seven more times.

Batten down the hatches, East Coasters: A new study argues that for every 1 degree C (1.8 degrees F) of global warming, the U.S. Atlantic seaboard could see up to seven times as many Katrina-sized hurricanes.

That’s the conclusion of Aslak Grinsted, a climatologist at Copenhagen’s Niels Bohr Institute, who led an effort to match East Coast storm surge records from the last 90 years with global temperatures. His results, published today in the Proceedings of the National Academy of Sciences, suggest that the strongest hurricanes are likely to become more commonplace with only half the level of warming currently projected by scientists.
