A SUPERSTORM IN 2100
What would happen to New York if the storm surge hurled at it by a storm like Sandy were riding on a sea that had risen five feet higher? That’s the high end of the range in 2100 that the U.S. Army Corps of Engineers now recommends planning for. Sandy’s surge flooded subway tunnels, knocked out the power grid in lower Manhattan for days, and damaged 218,000 cars in the region as a whole. If the city doesn’t protect itself, a future flood will surge farther and deeper into its cavernous streets.
