Researchers have found that the Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago.
Felipe Dana / AP fileThe Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study.has gone into hyperdrive in the last few years. Greenland’s average annual melt from 2017 to 2020 was 20% more a year than at the beginning of the decade and more than seven times higher than its annual shrinkage in the early 1990s.
But from 2017 to 2020, the newest data available, the combined melt soared to 410 billion tons a year, more than two-thirds of it from Greenland, said the study in Thursday’s journal“This is a devastating trajectory,” said U.S. National Snow and Ice Center Deputy Lead Scientist Twila Moon, who wasn’t part of the study. “These rates of ice loss are unprecedented during modern civilization.”
Greenland from 2017 to 2020 averaged about 283 billion tons of melting a year, compared to just 235 billion tons annually from 2012 to 2016. “While mass loss from Greenland is outpacing that from Antarctica, there are troublesome wild cards in the south, notably behavior of the Thwaites glacier,” which issaid Mark Serreze, director of the U.S. snow and ice center, who wasn’t part of the study.
