The remote and often unforgiving surface of Greenland’s ice sheet has long been a subject of intrigue for scientists. What lies beneath the thick layers of snow and ice has been largely a mystery, ...

The collapse of the world’s second-largest ice sheet would drown cities worldwide. Is that ice more vulnerable than we know?

Mapping cracks. In a new study, my colleagues and I mapped crevasses across the entirety of the Greenland ice sheet in 2016 and 2021.To do this, we used the "ArcticDEM": three-dimensional surface ...

New research reveals Greenland ice melt will cause a a 274 millimeter rise in sea levels — though an even bigger 700-plus millimeter rise could occur in a high-warming scenario.

At 656,000 square miles, the Greenland ice sheet currently covers around 80% of the island territory.To put that into perspective, it's about three times the size of Texas. Drill dome and camp for ...

A new large-scale study of crevasses on the Greenland Ice Sheet shows that those cracks are widening faster as the climate warms, which is likely to speed ice loss and global sea level rise ...

About 80 percent of Greenland is armored in a continuous sheet of ice, three times the area of Texas. But it hasn’t always been that way. At various points in Earth’s past, much of the island ...

But in 2019, while rinsing the sediment from the bottom of a core from Camp Century, a 1960s ice sheet boring site near the perimeter of the Greenland ice sheet, he saw familiar floating black flecks.

Ice loss in Greenland is already large, irreversible, and greatly accelerated after centuries of near stability. Though a tipping point for future ice loss has already been crossed, the pace of this ...

What’s old is new again. NASA scientists discovered an underground “city” buried 100 feet beneath the ice of Greenland. Researchers were shocked when their advanced radar technology picked ...
