Greenland Ice Sheet Melting at Fastest Rate in 350 Years

The Greenland ice sheet is melting faster today than at any point in the last 350 years, according to a new study published in the journal Nature.  The research is the first continuous, multi-century analysis of melting and runoff on the ice sheet, one of the largest drivers of sea level rise globally.

Lead by glaciologist and climate scientist Luke Trusel of Rowan University, a team of U.S. and European researchers analyzed more than three centuries of melt patterns in ice cores from western Greenland.  They then linked this historical data to modern observations of melting and runoff across the entire ice sheet, creating a timeline dating back to 1650.

“From a historical perspective, today’s melt rates are off the charts,” Sarah Das, a glaciologist at Woods Hole Oceanographic Institution and co-author of the new study, said in a statement.  “We found a 50 percent increase in total ice sheet meltwater runoff versus the start of the industrial era, and a 30 percent increase since the 20th century alone.”
