U.S. Atlantic Coast Already
‘Hotspot’ of Sea Level Rise, Study Says
A 600-mile stretch of the U.S. East Coast is experiencing rates of sea level rise that are three to four times greater than the global average
, according a new study. In a new analysis, scientists at the U.S.
Geological Survey (USGS) found that sea levels from Boston, Mass. to Cape Hatteras, N.C. have risen 2 to 3.7 millimeters per year since 1990, compared with a global average of 0.6 to 1 millimeters per year. According to the study, published in the journal Nature Climate Change
, sea levels appear to be rising in this mid-Atlantic region because a major Atlantic current that carries tropical water to the north is slowing down; that warmth expands seawater, which can lead to higher sea levels. “Many people mistakenly think that the rate of sea level rise is the same everywhere as glaciers and ice caps melt… [but] as demonstrated in this study, regional oceanographic contributions must be taken into account
in planning for what happens to coastal property,” said Marcia McNutt, director of the USGS. In a second study published in Nature Climate Change
, scientists predict that even if global temperature increases are limited to 2 degrees Celsius, global-mean sea level could rise as much as 4 meters above current levels
