travelUpdated: Apr 17, 2020 07:34 ISTClear skies and more sunlight over Greenland last summer resulted in the biggest drop in the ice sheet’s mass ever recorded, new research shows. As a result, about 50 billion fewer tons of snowfall fell over the ice sheet than average last year. It gained back just 50 billion tons, about 13% of the average increase between 1981 and 2010. That’s in part because surface mass losses aren’t the only way glaciers shrink. Overall, the Greenland ice sheet lost an estimated 600 billion tons in 2019, representing a sea level rise of about 1.5 millimeters.
