Rising sea levels threaten East Coast

By Jasmin Melvin WASHINGTON (Reuters) – Sea levels on the United States’ mid-Atlantic coast are rising faster than the global average because of global warming, threatening the future of coastal communities, the Environmental Protection Agency said on Friday. Coastal waters from New York to North Carolina have crept up by an average of 2.4 to 4.4 millimeters (0.09 to 0.17 inches) a year, compared with an average global increase of 1.7 millimeters (0.07 inches) a year, the EPA said in a report. As a result, sea levels along the East Coast rose about a foot over the past century, the EPA’s report, commissioned by the Climate Change Science Program, said. The EPA focused on the mid-Atlantic region because it "will likely see the greatest impacts due to rising waters, coastal storms, and a high concentration of population along the coastline," the agency said. Higher sea levels threaten to erode beaches and drastically change the habitats of species in the area, often at a pace too fast for species to adapt and survive, the EPA said. Communities in the area are at greater risk of flooding as a "higher sea level provides an elevated base for storm surges to build upon and diminishes the rate at which low-lying areas drain," the report found.
