Losing Ice at Fastest Rate Ever Recorded

Antarctic ice elevation
Ice sheets in Greenland and Antarctica are losing mass at an unprecedented rate of 500 cubic kilometers per year — enough ice to cover the Chicago metropolitan area with a layer of ice 600 meters thick — according to German researchers. Using data from the European Space Agency's CryoSat 2 satellite from 2011 to 2014, the team created the most detailed maps to date of ice elevations across Antarctica and Greenland, accurate to a few meters in height. The results reveal that Greenland alone is losing ice volume by about 375 cubic kilometers per year, doubling since 2009, the scientists report. Ice loss in the West Antarctic Ice Sheet has increased by a factor of three over the same period. Combined, the two ice sheets are thinning at the highest rate observed since altimetry satellite records began about 20 years ago, the study found. Data show that East Antarctica is gaining ice volume, but at a moderate rate that doesn’t compensate the losses on the other side of the continent.
