Still, one expert thinks that only part of East Antarctica is a concern. ![]() "We probably are seeing the result of a lot of long time increased ocean warming there," Walker said. Then in 2020, the shelf’s ice loss sped up to losing about half of itself every month or so, Walker said.ĪFTER: Aqua MODIS 21 March 2022: Shows the two pieces of C-38 (A and B icebergs) next to the main piece of C-37 at the top. Scientists had been seeing this particular ice shelf - closest to Australia - shrink a bit since the 1970s, Neff 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." There is mass loss starting to happen," Fricker said. ![]() Helen Amanda Fricker, co-director of the Scripps Polar Center at the University of California San Diego, said researchers have to spend more time looking at that part of the continent. It’s more than five times the ice in the more vulnerable West Antarctic Ice Sheet, where scientists have concentrated much of their research. 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 (50 meters). ![]() Neff said he worries that previous assumptions about East Antarctica’s stability may not be correct. ![]()
