Greenland’s massive cap of ice, containing enough fresh water to raise sea levels by 23 feet, is in serious trouble. Between 2002 and 2023, Greenland lost 270 billion tons of frozen water each ...

Dorthe Dahl-Jensen, a Danish ice-core climatologist, first came to the Greenland ice sheet in 1981. Back then, “no one was talking about global warming,” she says.

Long-lost samples of twigs and rocks show that Greenland once lost a tremendous amount of ice under climate conditions very much like the ones humans have created and are currently living in ...

The longest core of rock ever extracted from beneath Greenland’s thick ice could hold clues about how quickly the island’s frozen covering will melt as the planet warms. Preliminary analysis ...

Ice sheet modeling shows the location where the ice core was taken could have only been free of ice if other large parts of Greenland were also ice-free at the same time.

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.

Sediments recovered from the base of the Camp Century ice core show that northwestern Greenland was ice-free during a period of history known to have exhibited some of the lowest global ice ...

By coring the seabed at 850 m water depth in Disko Bay off Greenland's west coast, researchers from the University of Copenhagen have obtained the first historical record of plastic pollution in ...

A child walks on top of pieces of ice in Nuuk, Greenland on Feb. 16, 2025. (Emilio Morenatti/AP) Ice, ironically, defines Greenland. Up to almost two miles thick in places, the ice that envelops ...

Drilling of the Renland ice core in eastern Greenland was led by the University of Copenhagen, Denmark. About the OSU College of Earth, Ocean, and Atmospheric Sciences (CEOAS): ...

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 ...

Greenland's location between the U.S., Russia and Europe makes it strategic for both economic and defense purposes, especially as melting sea ice has opened up new shipping routes through the Arctic.
