In the Arctic, landslide-like features known as mega retrogressive thaw slumps are threatening infrastructure, altering regional biogeochemistry, and emitting carbon. Sometimes eroding more than 1 ...

Scientists have found evidence that the Asian continent was free of permafrost all the way to its northerly coast with the ...

Thawing permafrost threatens up to three million people in Arctic regions ... soils turn to quicksand and thaw slumps (a type of landslide) must be avoided. In Longyearbyen on Svalbard, ...

These “thaw slumps” measured several hundred feet wide and just as deep. Jaden Cockney, 17, clambered down the side of one slump as his boss, William Dillon, looked on cautiously.

It's the world's largest "retrogressive thaw slump," a pit that forms when permafrost thaw causes the ground to cave in, creating a landslide as the earth at its edges slumps into the pit.

As they expand and release long-frozen organic carbon, thaw slumps become part of the permafrost positive feedback loop, where the carbon dioxide and methane they emit contributes to global warming.

Permafrost thaw isn’t just an issue affecting Denali. The National Park Service is responsible for more than 85 million acres of land, and Alaska contains approximately 54 million of those acres ...

The effects of thawing permafrost go beyond emissions and are already clear for those living on the frozen land. That's something that Chris Burn, a senior professor in geography at Carleton ...

What is a permafrost thaw slump? Just imagine a massive hole with an area the size of more than nine football fields—and growing—where ice-cold ground once stood.

One study estimated that permafrost thaw could emit as much planet-warming gases as a large industrial nation by 2100 if industries and countries don't aggressively rein in their own emissions today.
