NATIONAL BRIEFING / NORTHEAST

New York, Boston and the northeastern U.S. coast are likely to see the world’s biggest sea level rise from global warming, a new study predicts. The coast could see an extra 8-inch rise in addition to however much the oceans rise overall by 2100, because of predicted changes in ocean currents, according to a study online in the journal Nature Geoscience.

The study, based on computer models, was by Jianjun Yin of the Center for Ocean-Atmospheric Prediction Studies at Florida State University.

“Those kind of rises in sea level, when placed on top of the storm surges we see today, put in jeopardy lots of infrastructure, including the New York subway system,” said Donald Boesch, president of the University of Maryland Center for Environmental Science, who wasn’t part of the study.
