The glaciers of Canada’s Arctic islands are irreversibly melting, researchers warn.

Jan Lenaerts of Utrecht University in the Netherlands and colleagues simulated ice loss in the Canadian Arctic Archipelago throughout the 21st century as temperatures warm. By around 2100, the islands’ glaciers may shed 12.4 trillion tons of ice, or 18 percent of their current volume.

That melting would raise global sea level 3.5 centimeters, the team reports online March 7 in Geophysical Research Letters. After Greenland and Antarctica, the archipelago will be the world’s third-largest source of sea level rise caused by vanishing ice.
