‘We Are Watching the Ice Sheet Hit a Tipping Point’: Greenland Melting Even Faster Than Feared

“The only thing we can do is adapt and mitigate further global warming—it’s too late for there to be no effect.”

While climate scientists have repeatedly raised alarm about the how human-caused global warming is driving “off the charts” ice loss in Greenland that will contribute to devastating sea level rise, a new analysis of a less studied region has ramped up those concerns, revealing that Greenland’s ice sheet is melting even faster than previously thought.

“We are watching the ice sheet hit a tipping point,” warned lead author Michael Bevis, a geodynamics professor at Ohio State University. “We’re going to see faster and faster sea level rise for the foreseeable future.”

Researchers often look at ice loss from large glaciers in Greenland’s southeast and northwest regions. However, this study, published Monday in the Proceedings of the National Academy of Sciences (PNAS), found that the most sustained ice loss during the decade following 2003 was in the island’s southwest region.

“Whatever this was, it couldn’t be explained by glaciers, because there aren’t many there,” noted Bevis. “It had to be the surface mass—the ice was melting inland from the coastline.” MORE
