Between 2011 and 2014, while humans were discovering dubstep and the wonder of selfies, Greenland was melting fast. It lost a trillion tons of ice in just three years, and the world neither noticed nor gave a damn.

That’s according to a new, open-access study published in Geophysical Research Letters, which used the European Space Agency’s CryoSat satellite, along with regional ice models, to show that recent melting of the Greenland ice sheet contributed twice as much to sea level rise (roughly 2.5 millimeters over the study period) as the prior two decades. In other words, Greenland—which has been visibly losing ice since the ‘90s—is melting at an accelerating rate.

This falls right in line with the picture Earth scientists have built by studying past ice sheet contractions. Namely, when ice starts melting, it doesn’t go in a plodding, linear fashion. It disintegrates quickly, resulting in large pulses of […]
