Sea Levels Are Rising-But in Greenland, They Will Fall

"Sea level in Greenland is actually projected to fall."

"According to the study, the decline in sea level will likely measure about 0.9 meters (nearly three feet) in a low-emissions future and 2.5 meters (8.2 feet) in a high-emissions future by the year 2100."

"Foremost among them is the rebound of land beneath the Greenland Ice Sheet, a mile-thick body of glacial ice that covers 80 percent of the island and is being lost to melting at a rate of roughly 200 billion tons each year."

"As the ice sheet loses mass, its gravitational pull on the sea surface decreases. That translates into sea level fall."

Sea levels around Greenland are projected to decline despite global sea-level rise, with estimated falls of about 0.9 meters under low emissions and 2.5 meters under high emissions by 2100. The primary causes are isostatic rebound as the Greenland Ice Sheet loses mass and the resulting reduction in the ice sheet's gravitational attraction on surrounding ocean water. The Greenland Ice Sheet is roughly a mile thick, covers 80 percent of the island, and is losing mass at about 200 billion tons per year. Gravitational changes may explain up to 30 percent of the regional sea-level fall.
