A new study finds that more than 120 trillion tons of ice in Greenland is no longer being fed by glaciers and is destined to melt away.
"I think starving would be a good phrase," for what's happening to the ice, Colgan said.
This is the first time scientists calculated a minimum ice loss — and accompanying sea level rise — for Greenland, one of Earth's two massive ice sheets that are slowly shrinking because of climate change from burning coal, oil and natural gas. Scientists used an accepted technique for calculating minimum committed ice loss, the one used on mountain glaciers for the entire giant frozen island.
"You have committed mass loss from the ice," Alley said in an email."In the same way most of the world's mountain glaciers and the edges of Greenland would continue losing mass if temperatures were stabilized at modern levels because they have been put into warmer air just as your ice cube was put in warmer tea."
