Mountain permafrost is warming and thawing worldwide due to climate change, with ground temperature being a key control of its mechanical stability. Heat conduction is the dominant mode of heat ...

Permafrost is the frozen layer of soil that’s under about 15% of land around the Northern Hemisphere. While technically material needs to be frozen for only two consecutive years to count as ...

Permafrost, or frozen soil, covers some 15 percent of land in the Northern Hemisphere, and thanks to human-driven climate change, it is fueling a vicious warming feedback loop. As rising global ...

One of the defining features of an arctic environment is permafrost, which covers almost 10% of Earth's surface and remains entirely frozen year round. With temperatures reaching more extreme levels ...

The Arctic and northern high latitudes are warming about 2–4 times faster than the global average, allowing ancient permafrost to thaw and release stored carbon. These permafrost soils currently store ...

Four years ago, Morris J. Alexie had to move out of the house his father built in Alaska in 1969 because it was sinking into the ground and water was beginning to seep into his home. “The bogs are ...

As Ted Schuur stepped along the edges of Smith Lake, a bubble surfaced from the muck underfoot. And then another. They're bubbles of methane, a potent heat-trapping gas made from decomposing plants ...
