Zombie ice from the massive Greenland ice sheet will eventually raise the global sea level by at least 10 inches (27 centimeters) on its own, according to a study released Monday.
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.
“It’s dead ice. It’s just going to melt and disappear from the ice sheet,” Colgan said in an interview. “This ice has been consigned to the ocean, regardless of what climate (emissions) scenario we take now.”
