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 ...

A recently-discovered ice core taken from beneath Greenland’s ice sheet decades ago reveals that much of the country was ice-free around 400,000 years ago – an alarming finding that could have ...

Measurements of cosmic-ray-produced 10Be and 26Al in a bedrock core from beneath the summit of the Greenland Ice Sheet show that Greenland was nearly ice-free for extended periods under ...

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

In 2017, ice core drilling began, with scientists collecting 900 meters (3,000 feet) of core that year and 750 more meters (2,500 feet) in 2018. With 900 meters left to go, the team anticipates ...

New ice core data shows Greenland is the warmest it’s been in more than 1,000 years. Scientists say warming in Greenland in the past may have been masked by local weather variability. But not ...

A rediscovered sample of frozen sediment, collected more than 50 years ago, highlights the vulnerability of Greenland’s ice sheet to a warming climate. By Emily Anthes In 1966, scientists at ...

A sharp rise in Greenland temperatures since 1995 showed the giant northern island 2.7 degrees higher than its 20th century average, the highest in more than 1,000 years, according to new ice core ...

The core was subglacial sediment and rock, taken from below a mile of ice in 1966 at Camp Century, an American research base in Greenland that had served as cover for a secret—and failed ...

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.

BUFFALO, N.Y. — If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 ...
