As glaciers shrink, eroded rock from surrounding mountain slopes becomes exposed and slides down, forming a layer on the surface of glaciers which, if thick enough, reduces the rate at which the ice below melts. This work reveals that 44% of the world\u2019s glaciers are covered in debris, with Alaska, the Southwestern Himalayas, and Greenland having the greatest absolute cover. Rock debris cover has been long omitted from global-scale glacier models, and models neglecting debris cover and its evolution might be overestimating glacier melt in these regions, the authors suggest, underscoring the complexity of individual glacier dynamics.<\/p>\n<p><a href=\"http:\/\/www.nature.com\/articles\/s41561-020-0615-0\">http:\/\/www.nature.com\/articles\/s41561-020-0615-0<\/a><\/p>\n<p>Compiled by Amy Imdieke<\/p>","protected":false},"excerpt":{"rendered":"<p>Nature Geoscience, August 3 An updated approach is required to estimate the melting of global glaciers due to rock debris partially insulating the glaciers&#8217; surface.
