Woods Hole Study - Avg Rate of US Sea-Level Rise Has More Than Doubled Since 1900
The rate of sea-level rise along U.S. coastlines has more than doubled over the past 125 years, according to a new analysis that examined data from scores of tide gauges from around the country. The findings stand in contrast to a wide-ranging, widely criticized assessment of climate science that the Trump administration released this summer.
Chris Piecuch, a sea-level scientist at Woods Hole Oceanographic Institution, said he undertook his analysis in response to that Energy Department report, which he and others argue uses cherry-picked data to conclude that “U.S. tide gauge measurements reveal no obvious acceleration beyond the historical average rate of sea-level rise.”
Piecuch said that while the rate of rising seas varies from place to place, the full range of available data leads to “a dramatically different conclusion” about what is actually unfolding along the nation’s coastlines.

That assessment also underscores that some places, such as the Pacific Coast, have experienced little sea-level rise compared with places such as the gulf coast. Some spots in Alaska have even seen an overall decrease as sea-level rise is outpaced by a phenomenon known as “glacial rebound,” where the land lifts as glaciers recede. Piecuch is quick to acknowledge that there are indeed many such local forces at work, leading different areas of the country to record higher or lower rates of “relative” sea-level rise. But the overall trajectory, he said, is anything but murky. “None of those factors would cause the large-scale, nationwide sea-level acceleration that’s clearly seen when you look at U.S. tide gauges in aggregate,” he said.
