Scientists broadly agree that on a worldwide basis, sea level, already 8 inches higher than it was in 1900, is likely to go up by another 3 feet or so by the end of this century. That’s a global average.
However, depending on local conditions, the change could be less in some areas, and greater, along with a greater threat to life and property, in others.
The new study, which reinforces research published in Nature Climate Change last June, says that the northeastern U.S. falls into the “greater” category.
The increase was most evident at the eight stations with continuous records stretching back 75 years or more: Halifax, Nova Scotia; Portland, Maine; Boston; New York’s Battery; Sandy Hook and Atlantic City, N.J.; Baltimore, and Norfolk.
Eight more stations in the same region, with records going back 43 years, also showed acceleration, although the speedup was less clear due to the shorter observation period.
