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 ...

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 ...

New evidence that Greenland lived up to its verdant name in the recent past heralds ominous possibilities for future sea level rise.

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 ...

A rediscovered sample of frozen sediment, collected more than 50 years ago, highlights the vulnerability of Greenland’s ice sheet to a warming climate.

Temperatures soared to record levels in Greenland early this week, up to 50 degrees above normal in some places. Researchers say this early warm spell could make its ice sheet more vulnerable to ...

In the 1960s, the U.S. built a nuclear-powered city inside underground tunnels carved into Greenland's ice sheets and then abandoned it. Here's the full story.

A mile-long ice sample extracted by the U.S. military while it was studying whether to arm Greenland with nuclear missiles is filled with perfectly preserved insects and plants from hundreds of ...

Core sample analysis paints a 'foreboding wake-up call' in terms of the island's ice sheets in the face of climate change.

Scientists have been trying for decades to uncover the true geology of Greenland, an island one-third the size of Australia and almost entirely concealed under mile-deep ice sheets. For a recent ...
