Greenland’s meltdown melts faster today than ever before in the last 350 years, according to a new study published in the magazine Nature . Research is the first continuous analysis of melting and irrigation on the ice, one of the biggest driving forces at sea level globally.
Leader of Glaciologist and Climate Researcher Luke Trusel of Rowan University, a team in the United States and European researchers analyzed more than three centuries melting patterns in ice-cores from western Greenland. They then linked these historical data to modern observations of melting and drainage throughout the ice, creating a timeline from 1650.
“From a historical perspective, today’s melting frequencies are outside the charts”, Sarah Das, a glaciologist at Woods Hole Oceanographic Institution and co-authors of the new study, said in a statement. “We found an increase of 50 percent of the total meltwater drainage in the ice against industry’s age and an increase of 30 percent since the 20th century.”
According to the analysis, the melting of the green ice was spread in the mid 1
800s, just after the start of the industrial era of the Arctic. Over the last 20 years, the melt intensity has increased 250-575 percent compared to pre-industrial melting speeds. Over the ice melting was faster in 2012 than any other year, and the last decade included in the ice core analysis 2004-2013 experienced “a more durable and greater melting glue than any other 10-year period.” In the 350-year record, the researchers wrote.
“The melting does not only increase – it accelerates,” said Trusel Nature . “And that’s an important issue for the future.”
Greenland ice is the largest single contributor to the global sea level today and adds 72 cubic miles of melt water to the world’s ocean. The ice has the potential to raise the global sea level by 23 meters if it melts in its entirety.
