Ocean water along U.S. coasts will rise about one foot by 2050, scientists warn

Low-lying neighborhoods in South Florida are vulnerable to the seasonal flooding caused by king tides. While higher seas cause much more damage when storms such as hurricanes hit the coast, they are getting to the point where it doesn’t have to storm to be a problem.

Sea levels along coastlines in the United States will rise about one foot by 2050, with larger increases on the East and Gulf coasts, according to a comprehensive new report by federal climate scientists.

Oceans have already risen about one foot in the last century, as climate change melts glaciers and ice caps around the world. But the pace is accelerating, scientists warn, and the next 30 years will see the same amount of sea level rise as the previous 100.

“It’s like history is repeating itself, but in fast-forward,” says William Sweet, a sea level rise expert with the National Oceanic and Atmospheric Administration (NOAA) and one of the authors of the new report.
