The Greenland ice sheet lost 20 percent more ice than scientists previously thought, posing potential problems for ocean circulation and sea level rise, a study says.

With the arrival of summer, the Greenland Ice Sheet has adopted its ‘summer look,’ revealing a few odd shapes and other ...

The area of Greenland’s ice loss in the past three decades is 36 times the size of New York City — land that is rapidly giving way to wetlands and shrubs, a study shows.

Until now, Greenland ice cores hadn’t shown a clear signal of global warming, but data also hadn’t been updated since 1995.

Greenland Ice Sheet melting faster than previously thought, scientists say Melting in the Arctic could have catastrophic consequences for the planet.

A sharp spike in Greenland temperatures since 1995 showed the giant northern island 2.7 degrees (1.5 degrees Celsius) hotter than its 20th-century average, the warmest in more than 1,000 years ...

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 ...

Scientists found that Greenland's Jakobshavn glacier -- it's fastest-melting glacier for 20 years -- is extremely sensitive to ocean temperatures.

Scientists have warned about the fate of Greenland's ice sheet and say what happened between July 15 and 17 is the latest massive melting event contributing to an increase in the global sea level.

Greenland’s ice-covered landscape looks like an immovable block on satellite maps. Yet the story beneath its center suggests ...

The Eurasian Ice Sheet retreated by 2,000 feet a day during the last ice age, a study finds. It may show how fast ice and glaciers in Greenland and Antarctica could melt and raise sea levels today.

What is happening at the grounding line -- the junction between a grounded ice sheet and the ocean -- led the researchers to discover much more melting that previously thought at Petermann Glacier ...
