New satellite-based research reveals how land along the coast is slumping into the ocean, compounding the danger from global sea level rise.

A major culprit: overpumping of groundwater.

The most vulnerable areas of Boston have been sinking up to 3.8 centimeters per decade, which adds up to nearly 10 centimeters by 2050, based on the analysis of satellite data from 2007 to 2020.

Parts of New York City and Long Island are sinking over 3 centimeters per decade.

Atlantic City is sinking up to 4 centimeters per decade. Nearby groundwater pumping has caused soils to compact.

Several hotspots in Maryland are sinking over 10 centimeters per decade, while other areas are rising. Adjacent land moving at different rates can put infrastructure at risk.

Hampton Roads, Va., which is sinking over 2 centimeters per decade, is pumping treated wastewater underground to try to slow the pace.

Charleston, S.C., which is affected by groundwater pumping, is sinking up to 5.7 centimeters per decade.

Northeast Florida has experienced some rising, up to about 1 centimeter per decade, as erosion of […]
