Surface Lake Melt in Greenland Causing Ice Sheet to “Slip Away”
25.04.2012
According to results of a study by a team of researchers from the University of Colorado at Boulder, the Greenland Ice Sheet is slipping into the ocean at a faster rate due to “catastrophic lake drainages” – when huge amounts of meltwater from surface lakes on top of the ice…
