That’s the point where glaciers go from being on land to floating on water. The study looks at the all-important grounding line area of glaciers on ice sheets. He said this newly found consequence of tidal activity “could potentially double the projections” of global melt. We know that they have a really hard time matching the current record’' of melt. “We know the current projections are too conservative. “It’s bad news,” said study author Eric Rignot, a glaciologist at University of California Irvine. If it is happening in the rest of Greenland and the even bigger Antarctic ice sheet, then global ice loss and the sea level rise could jump as much as twice as fast as previously thought, according to the study in Monday’s Proceedings of the National Academy of Sciences. The rapid melt seen in this study was in the far northwest of Greenland on Petermann Glacier. Daily tides stoked with increasingly warmer water ate a hole taller than the Washington Monument at the bottom of one of Greenland’s major glaciers in the last couple years, accelerating the retreat of a crucial part of the glacier, a new study found.Īnd scientists worry that the phenomenon isn’t limited to this one glacier, raising questions about previous projections of melting rates on the world’s vulnerable ice sheets.
