'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.'
While areas of the Arctic experience temperatures 50 degrees above normal, weather in the South Pole is roughly 70 degrees warmer than average.
The ice shelf, about 460 square miles wide holding in the Conger and Glenzer glaciers from the warmer water, collapsed between March 14 and 16, said ice scientist Catherine Walker of the Woods Hole Oceanographic Institute. She said scientists have never seen this happen in this part of the continent, making it worrisome.
The issue isn't the amount of ice lost in this collapse, Neff and Walker said. That is negligible. It's more about the where it happened.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 .
