As the Greenland Ice Sheet Retreats, Mercury is Being Released From the Bedrock Below
Scientists have found that Greenland’s bedrock is rich with mercury in some areas — and as the ice sheet rapidly melts, that mercury is being released into local waters.

Fossil Plants at Bottom of the Greenland Ice Sheet Warn of Future Melting
The discovery of fossil plants below a mile of Greenland ice indicates that the ice sheet completely melted in the past, and suggests it could rapidly do so again.

Scientists Have Discovered an Ancient Lake Bed Deep Beneath the Greenland Ice
Using radar and other techniques, researchers have mapped out the sediments left by a lake that apparently existed before Greenland was glaciated. Next step: drilling through the ice to see what they contain.

Scientists Harness Satellites to Track Algae Growth on Greenland Ice Sheet
To measure algal blooms across large regions of the Greenland ice, and understand their effects on melting over time, scientists are turning to space.

Greenland on Track to Lose Ice Faster Than in Any Century Over the Last 12,000 Years
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 since shortly after the end of the last ice age, a new study concludes.

Greenland Ice Sheet Reached Tipping Point 20 Years Ago, New Study Finds
The massive ice sheet is now locked into a certain amount of decline. But reducing emissions remains critical to preventing catastrophic loss of the entire ice sheet.

Greenland Ice Sheet Saw Record Loss in 2019
An international team of polar researchers says that the Greenland ice sheet experienced record loss in 2019.

How Catastrophic Floods May Have Carved Greenland’s ‘Grand Canyon’
In a new study, researchers propose a mechanism for how mega-canyons under northern Greenland’s ice sheet formed: from a series of catastrophic outburst floods that suddenly and repeatedly drained lakes of meltwater.

Unusually Clear Skies Drove Record Loss of Greenland Ice in 2019
Study identifies unprecedented atmospheric conditions behind devastating summer; suggests climate models may greatly underestimate future melting.
