Icebergs seen through the fog float in the Baffin Bay near Pituffik, Greenland on July 20, 2022 as captured on a NASA Gulfstream V plane while on an airborne mission to measure melting Arctic sea ice. - New observations from ICESAT-2 show remarkable 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 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."RELATED: Melting ice uncovers Viking Age artifacts as climate change creates ‘boon’ for archaeologistsStudy lead author Jason Box, a glaciologist at the Greenland survey, said it is "more like one foot in the grave.""Today is a day of celebration, a day we take another giant step in our momentous agenda," said House Speaker Nancy Pelosi, D-Calif., who minutes later announced the final vote as she presided over the chamber.
She said the measure "meets the moment, ensuring that our families thrive and that our planet survives."The unavoidable ten inches in the study is more than twice as much sea level rise as scientists had previously expected from the melting of Greenland’s ice sheet.
