The rate of sea level rise along much of the U.S. coastline continues to accelerate, according to a new report.
The report’s key message “is a clear trend toward acceleration in rates of sea-level rise at 25 of our 32 tide-gauge stations,” said Virginia Institute of Marine Science emeritus professor John Boon in a statement. “Acceleration can be a game changer in terms of impacts and planning, so we really need to pay heed to these patterns.”
Boon and other researchers at William & Mary’s Virginia Institute of Marine Science released the report Monday.
Sea-level rise acceleration was highest along the Gulf Coast, where Grand Island, Louisiana, saw a nearly 8 millimeter yearly increase, which is double the global average, according to the report. Galveston and Rockport in Texas also had significant increases.
The report includes 51 years of water-level observations, from January 1969 through December 2019.
