A tidewater glacier is seen in southeast Greenland during summer 2018. (Eric Rignot) Greenland, home to Earth’s second-largest ice sheet, has lost ice at an accelerating pace in the past several decades — a nearly sixfold increase that could contribute to future sea level rise, according to a new study based on nearly a half-century of data. The findings, published Monday in the Proceedings of the National Academy of Sciences, estimate that Greenland’s glaciers went from dumping about 51 billion tons of ice into the ocean between 1980 to 1990, to losing 286 billion tons between 2010 and 2018. The result is that out of nearly 14 millimeters of sea level rise in total caused by Greenland since 1972, half of it has occurred in just the past eight years, researchers found. And the losses are likely to get worse. The regions with the biggest potential ice loss — […]
