Greenland’s ice sheet melt has ‘gone into overdrive,’ study says
The melting of Greenland’s massive ice sheet has accelerated and shows no signs of slowing down, according to a study released Wednesday in the British journal Nature.
“Melting of the Greenland ice sheet has gone into overdrive,” said Luke Trusel, a glaciologist at Rowan University and lead author of the study.
“Greenland melt is adding to sea level more than any time during the last three and a half centuries, if not thousands of years,” he said.
Ice loss from Greenland is the largest contributor to global sea-level rise, which is predicted to lead to inundation of low-lying islands and coastal cities.
“From a historical perspective, today’s melt rates are off the charts, and this study provides the evidence to prove this,” said co-author Sarah Das, a glaciologist at the Woods Hole Oceanographic Institution.
Specifically, the melt rate over the past two decades was 33 percent higher than the 20th-century average.
