GEOGRAPHY IN THE NEWS:
A new report finds that the planet is losing 1.2 trillion tons of ice each year, up from 760 billion tons in the 1990s, and the pace of ice loss is accelerating. Scientists used satellite data to study land and sea ice and found the areas experiencing the greatest loss of ice are Greenland and Antarctica, where warming water is eating away at glaciers and ice sheets where they meet the sea. Moreover, the report finds that previous estimates fail "to fully account for the role of ocean undercutting" and sea-level rise from melting ice "may be underestimated by 'at least a factor of 2.'” ... “'It’s like cutting the feet off the glacier rather than melting the whole body,' said Eric Rignot, a study co-author and a glacier researcher at NASA’s Jet Propulsion Laboratory and the University of California at Irvine. 'You melt the feet and the body falls down, as opposed to melting the whole body.'” www.washingtonpost.com/climate-environment/2021/01/25/ice-melt-quickens-greenland-glaciers
