New York Seas to Rise Twice as Much as Rest of U.S.

Sea levels around New York City and much of the U.S. Northeast will rise twice as much as in other parts of the United States this century, according to new climate models (U.S. Northeast map). Driven by changes in ocean circulation, the rapid sea level rise will bring increased risk of damage from hurricanes and winter storm surges, researchers say.

“Some parts of lower Manhattan are only 1.5 meters [5 feet] above sea level,” said lead study author Jianjun Yin, a climate modeler at Florida State University.

“Twenty centimeters [8 inches] of extra rise would pose a threat to this region.”

Yet New York, Boston, and Washington, D.C., area seas will rise 14 to 20 inches (36 to 51 centimeters) by 2100, according to the study, published online today in the journal Nature Geoscience.

Other U.S. cities, such as Miami and San Francisco, are expected to see only half as big an increase in sea levels.
