Green­land's mages­tic moulins get rouged

Science Illustrated - - CLIMATE -

Green­land’s ice sheet is melt­ing faster than at any point in the past 400 years, and that makes rivers of melt­wa­ter gush across the sur­face. The melt­wa­ter is work­ing its way down through the ice sheet, caus­ing deep shafts known as moulins. In or­der to map out the melt­wa­ter’s route, sci­en­tists use a flu­o­res­cent red dye that is harm­less to the en­vi­ron­ment. The melt­wa­ter prob­a­bly func­tions as lu­bri­ca­tion, mak­ing the ice skid faster across the be­drock, so more ice ends up in the sea in the form of ice­bergs.
