Past Greenland Ice Sheet Melting May Reveal Future Sea-Level Rise

Greenland is melting, so what does this mean for the future? In order to find out, a team of scientists looked to the past and quantified how the Greenland Ice Sheet reacted to a warm period that occurred 8,000 to 5,000 years ago.

New 3D View of Greenland Ice Sheet Reveals Climate History

Scientists are learning a bit more about Greenland's ice sheet with the help of some new technology. They've used ice-penetrating radar data collected by NASA's Operation IceBridge to build the first ever comprehensive map of layers deep inside the Greenland Ice Sheet.

Subglacial Lakes Beneath the Greenland Ice Sheet Refill with Meltwater

Scientists have made a surprising discovery beneath the Greenland Ice Sheet. While building the highest-resolution map yet of this ice sheet, they found two lakes of meltwater that pooled beneath the ice and rapidly drained away.

'Missing' Water from Greenland Ice Sheet Found by Studying Meltwater Rivers

Scientists are taking a closer look at Greenland's ice sheet, and have discovered just how much meltwater is contributing to rising sea levels. They've found evidence that the rivers and streams flowing on top of the ice sheet could be major contributors to rising seas.

Why Greenland is Covered in Ice: Processes Deep Beneath Earth's Surface

Why is Greenland covered in ice? Scientists have taken a closer look, and have found that the ice on Greenland could only form due to processes deep in the Earth's interior.

Greenland's Vanishing Ice Sheet is Melting Faster Than Previously Thought

Most people are aware that the Greenland Ice Sheet is melting. Yet exactly how fast that melting is occurring has been up for debate.

Migrating Supraglacial Lakes on the Greenland Ice Sheet May Cause Major Melting

It turns out that Greenland's ice loss and its impact on rising sea levels may have been greatly underestimated. Scientists have found that migrating, supraglacial lakes could trigger future ice loss which, in turn, may add to rising sea levels.

Greenland Ice Sheet's Meltwater Channels Reveal More Complicated Picture

Things are more complicated in Greenland than we once thought. Scientists that are drilling and measuring the melt rates and ice sheet movement in Greenland have found that channels beneath the ice could make simplistic models inaccurate.

Greenland Ice Sheet is More Vulnerable to Climate Change Due to Mushy Underside

Scientists have created a new model that shows that despite its apparent stability, the Greenland Ice Sheet is more sensitive than earlier estimates suggested.

Scientists Resolve Temperature 'Paradox' in Greenland Temperatures During Last Ice Age

Scientists have taken a closer look at the ancient past of Greenland to find out a bit more about the landmass's climate. By studying three ice cores, scientists have found that there was warming of the large ice sheet at the end of the last ice age, resolving a long-standing paradox over when the w...
