In western Siberia, a rare kind of gas explosion is carving deep, near vertical craters in the tundra. Some of these massive ...

Researchers found that ice can trigger stronger chemical reactions than liquid water, dissolving iron minerals in extreme ...

ALEXANDER: Run-of-the-mill permafrost we generally consider one to two meters deep. Yedoma, on the other hand, can go ...

Scientists warn warming permafrost is a tipping point: alpine sinks weaken, Arctic plants thrive, and methane and nitrous oxide climb.

Researchers in Oslo found that the origin of the giant holes in Siberia is not caused by climate change and permafrost thaw ...

Ice can dissolve iron minerals more effectively than liquid water, according to a new study from Umeå University. The ...

Ice does something unexpected to dissolving iron—and it could help explain the Arctic’s strange orange rivers.

Warming of 2°C boosts Arctic permafrost's carbon sink, but this is substantially offset by a weakening sink in alpine regions ...

Warming Arctic permafrost is unlocking toxic metals, turning Alaska’s once-clear rivers into orange, acid-laced streams. The shift, eerily similar to mine pollution but entirely natural, threatens ...

In Alaska's Brooks Range, rivers once clear enough to drink now run orange and hazy with toxic metals. As warming thaws formerly frozen ground, it sets off a chemical chain reaction that is poisoning ...

Permafrost - ground that remains frozen for at least two years - blankets roughly 17% of the Earth's land surface, mostly in ...
