It happened at the beginning of a freakish warm spell last week when temperatures soared more than 70 degrees warmer than normal in some spots of East Antarctica. Satellite photos show the area had been shrinking rapidly the last couple of years, and now scientists wonder if they have been overestimating East Antarctica’s stability and resistance to global warming that has been melting ice rapidly on the smaller western side and the vulnerable peninsula.
“The Glenzer Conger ice shelf presumably had been there for thousands of years and it’s not ever going to be there again,” said University of Minnesota ice scientist Peter Neff. Neff said he worries that previous assumptions about East Antarctica’s stability may not be correct. And that’s important because if the water frozen in East Antarctica melted — and that’s a millennia-long process if not longer — it would raise seas across the globe more than 160 feet . It’s more than five times the ice in the more vulnerable West Antarctic Ice Sheet, where scientists have concentrated much of their research.
“East Antarctica is starting to change. There is mass loss starting to happen,” Fricker said. “We need to know how stable each one of the ice shelves are because once one disappears” it means glaciers melt into the warming water and “some of that water will come to San Diego and elsewhere.”
