A new study finds that Greenland has more than 120 trillion tons of ice that can be thought of as zombie ice that's going to raise sea level globally by at least 10 inches. 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 on 29 August 2022. 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 Dr William Colgan, a glaciologist at the Geological Survey of Denmark and Greenland.
