WASHINGTON: Greenland is becoming darker and warmer due to a weather pattern that is pushing fresh snowfall away from its ice sheet, a study said Monday.
A reduction in the amount of fresh, light-colored snow leaves more old and dark snow exposed on the surface which in turn causes the ice sheet to absorb more heat and melt faster. As snow ages, even over hours to a few days, you get this reduction in reflectivity, and that s why the fresh snow is so important, said Erich Osterberg, an associate professor of earth sciences at Dartmouth College and co-author of the paper in Geophysical Research Letters.
