East Coast a Hotspot for Rapid Sea Level Rise
Property values aren’t all that’s been rising in Manhattan. The height of the water lapping up against the Big Apple and many East Coast cities has been creeping up faster in recent decades.
“We have direct evidence of a hot spot stretching from Cape Hatteras in North Carolina to just above Boston,” says Asbury Sallenger Jr., an oceanographer at the U.S. Geological Survey’s St. Petersburg Coastal and Marine Science Center in Florida. “The area has an unusual sea level rise acceleration compared to the rest of the United States.” Global warming could be driving the acceleration, researchers report online in Nature Climate Change. With temperatures still climbing, further ocean rises could increase the risk of flooding, encroach on wetlands and give hurricane storm surges extra punch.
