As the seas rise, a slow-motion disaster gnaws at America’s shores


By Ryan McNeill, Deborah J. Nelson and Duff Wilson – Since 2001, water has reached flood levels an average of 20 days or more a year in Annapolis, Maryland; Wilmington, North Carolina; Washington, D.C.; Atlantic City, New Jersey; Sandy Hook, New Jersey; and Charleston, South Carolina.

Before 1971, none of these locations averaged more than five days a year.

Annapolis had the highest average number of days a year above flood threshold since 2001, at 34. On the Delmarva Peninsula, the annual average tripled to 18 days at the Lewes, Delaware, tide gauge.

“In the U.S., you have best data set on what’s happening in the world, and yet it’s not used in public policy,” said Robert Nicholls, professor of coastal engineering at the University of Southampton in England. more> http://tinyurl.com/kqqojj4
