Camden, NJ, United States (4E) – The melting of Greenland’s massive ice sheet is off the charts.
A new study proves the melting of ice in this massive island has vastly accelerated and shows no signs of tapering-off.
“Melting of the Greenland ice sheet has gone into overdrive,” said Luke Trusel, a glaciologist at Rowan University and lead author of the study. “Greenland melt is adding to sea level more than any time during the last three and a half centuries, if not thousands of years.”
The published study found that Greenland’s ice loss has accelerated rapidly over the past two decades after remaining relatively stable since the dawn of the Industrial Revolution in the mid-1800s.
Greenland’s ice sheets are now melting at a rate 50% higher than pre-industrial levels and 33% above 20th-century levels, said the study.”What we were able to show is that the melting that Greenland is experiencing today is really unprecedented and off the charts in the longer-term context,” said Sarah Das, an associate scientist at the Woods Hole Oceanographic Institution and a co-author of the study.
Scientists affirm ice loss from Greenland is the single largest cause to global sea-level rise. This rise is predicted to result in the inundation of low-lying islands and coastal cities around the world.
Conservative estimates see global sea level rise adding half a meter or more by 2100 . Experts saud half a meter is “a terrible disaster for humanity – especially coastal regions of the planet.”
Eight of the 10 largest cities in the world are near coasts. Some 40% to 50% of the global population lives in coastal areas vulnerable to sea-level rise.
“From a historical perspective, today’s melt rates are off the charts, and this study provides the evidence to prove this” said co-author Sarah Das. In just one year (2012), enough ice melted into water to fill up about 240 million Olympic swimming pools.
