Collecting core samples from the Greenland ice sheet is no easy task. During a recent expedition, scientists and drilling experts boarded a ski-equipped aircraft and flew to a site at…
Everything about the Greenland shark seems to be slow: these long-bodied animals swim slowly, grow slowly and reach maturity slowly. Their maturity rate is so sluggish, in fact, that scientists…
Discussions about the Greenland ice sheet often focus on what it’s losing. But from around the edges of the rapidly melting Greenland ice sheet, a global commodity is being created.…
In the Davis Strait between Greenland and Canada’s Baffin Island, where only the faintest rays of sunlight penetrate, swim strange-looking flat fish with both eyes on the right side of…
When Kristin Laidre began working on a long-term project to study polar bears in eastern Greenland, she didn’t expect to find a new subpopulation of the species — and she certainly…
An Australian mining company hoping to build a vast open-cut rare earths and uranium mine on a mountain in southern Greenland has told shareholders it will persist with the project…
More than a decade after the Planetary Boundaries framework was first proposed by top scientists, we are no closer to changing our destructive trajectory — but 2021 gives us three opportunities to act.
New research finds that ice in both polar regions, and especially sea ice, is disappearing at a quickening rate, while in the Arctic the last stronghold of multiyear ice is under assault from warming.
Over the past twenty years the concept of "tipping points" has become more familiar to the public. Tipping points are critical thresholds at which small changes can lead to dramatic…
The Greenland Ice Sheet is losing mass, and there may be no way to stop it, scientists have concluded. Even if large amounts of snowfall return to the ice sheet,…
As 2019 melt season nears end, 40 years of satellite data reveal a rapidly warming polar region, with no end in sight, plus multiple impacts for a changing planet. This story has been updated.
Until recently, researchers knew of four lakes lying hidden underneath the Greenland ice sheet. Now, scientists say they’ve identified 56 more, bringing the total to 60 known subglacial lakes beneath…
Though sea ice extent was up across much of the Arctic at winter maximum, the Bering Sea lost an ice area the size of Montana, and Greenland has been receiving winter rains.
At the start of August, for the second time this year, a corridor of open water developed along the north shore of Greenland, this one more than 100 kilometers (over…
A new study finds that more frequent Arctic extreme weather, such as rain-on-snow events, result in smaller head size and possibly lower survival rates in muskox young.
WildTech asks Dr. Henrik Rasmussen of Savannah Tracking about shifting careers from biologist to engineer.
