Researchers had previously estimated that the Greenland ice sheet lost about 5,000 gigatons of ice in recent decades, enough to cover Texas in a sheet 26 feet high. Glaciers in Greenland accumulate mass and grow throughout the winter, then experience ice loss throughout the summer. But “there is no evidence that it has affected the ocean circulation so far.”That’s not too unexpected at the moment. AdvertisementBut continued ice loss and meltwater from Greenland will become a problem in the long term, said Straneo, a professor of oceans and climate at Scripps Institution of Oceanography. One model showed that continued ice loss from Greenland will reduce the AMOC by 15 percent over 50 years, with substantial weakening by 2100.
