Greenland's Ice Melt Is in 'Overdrive,' With No Sign of Slowing

The ice sheet is adding more to sea level rise than any time in the last three and a half centuries, new research suggests. Could it be nearing a tipping point?

Melting on Greenland's ice sheet has gone into "overdrive," with meltwater runoff increasing 50 percent since the start of the industrial era and continuing to accelerate, new research shows. As more water runs off the ice sheet, it drives sea level rise, putting new pressure on coastal communities around the world.

"Once the ice sheets get kicked into motion, they just keep going. This is a wake-up call that shows how fast Greenland is changing," said Rowan University climate researcher Luke Trusel, co-author of the new study published Wednesday in the scientific journal Nature.

The scientists found that the trend of increasing surface melting across the ice sheet began in the mid-1800s as greenhouse gas emissions from the growth of industries were ramping up, and that it shot up over the past three decades. More meltwater is running off Greenland's ice sheet now than at any time in the last 350 years, and probably since long before that, going back 6,000 to 7,000 years, Trusel said.

As a result, Greenland is also adding more to sea level than at any time over the past three and a half centuries, he said.

The findings support previous estimates that melting ice from all sources will raise sea level between 8 and 12 inches more by 2050, but what happens after that will still partly depend on future greenhouse gas emissions and other factors, said co-author Sarah Das, who studies ice and ancient climates at the Woods Hole Oceanographic Institution.

Going to be Even colder there than it already is going forward?

That would really suck.

Never understood why they didn't call Greenland Iceland and Iceland Greenland.
