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. ![]()
