Greenland Melting Is ‘Off the Charts’
The first continuous, multi-century study of surface melt from the Greenland ice sheet was published in Nature Wednesday, and the results are clear: the ice sheet is now melting at rates unseen within at least the last 350 years.
"Melting of the Greenland Ice Sheet has gone into overdrive. As a result, Greenland melt is adding to sea level more than any time during the last three and a half centuries, if not thousands of years," lead study author and Rowan University School of Earth & Environment glaciologist Luke Trusel said in a press release from the Woods Hole Oceanographic Institution (WHOI), one of the institutions involved in the research.
The researchers found that melting first increased on the ice sheet in the 1800s, when the Arctic began to warm as the process of industrialization started pumping greenhouse gasses into the atmosphere. However, it is only in recent decades that the melting has increased beyond the point of natural variability. There is now 50 percent more meltwater runoff entering the oceans from the sheet since the start of the industrial era, and 30 percent more since the 20th century.
"From a historical perspective, today's melt rates are off the charts, and this study provides the evidence to prove this," WHOI glaciologist and study author Sarah Das said.
