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.
