Zombie ice from the massive Greenland ice sheet will eventually raise global sea level by at least 10 inches (27 centimeters) on its own, according to a study…
Zombie or doomed ice is ice that is still attached to thicker areas of ice, but is no longer getting fed by those larger glaciers. That’s because the parent glaciers are getting less replenishing snow. Meanwhile the doomed ice is melting from climate change, said study co-author William Colgan, a glaciologist at the Geological Survey of Denmark and Greenland.We deliver the local news you need in these turbulent times on weekdays at 3 p.m.
What scientists did for the study was look at the ice in balance. In perfect equilibrium, snowfall in the mountains in Greenland flows down and recharges and thickens the sides of glaciers, balancing out what’s melting on the edges. But in the last few decades there’s less replenishment and more melting, creating imbalance. Study authors looked at the ratio of what’s being added to what’s being lost and calculated that 3.
“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.”Article content
