Zombie Ice From Greenland Will Raise Sea Level 10 Inches

(AP) -- Greenland’s rapidly melting ice sheet will eventually raise global sea level by at least 10.6 inches (27 centimeters) -- more than twice as much as previously forecast — according to a study published Monday.

That's because of something that could be called zombie ice. That's doomed ice that, while still attached to thicker areas of ice, is no longer getting replenished by parent glaciers now receiving less snow. Without replenishment, the doomed ice is melting from climate change and will inevitably raise seas, said study co-author William Colgan, a glaciologist at the Geological Survey of Denmark and Greenland.
