Warmer temperatures in the Arctic are thawing the region’s permafrost — a frozen layer of soil beneath the ground — and potentially stirring viruses that, after lying dormant for tens of ...

The Tibetan Plateau hosts the world's largest permafrost region in the middle and low latitudes. Compared to the high-latitude Arctic permafrost, the permafrost here is thinner, warmer, and more ...

Thawing permafrost — the long-frozen layer of soil that has underpinned the Arctic tundra and boreal forests of Alaska, Canada and Russia for millennia — is upending the lives of people such ...

Viruses Scientists revive 48,500-year-old ‘zombie virus’ from Siberian permafrost Revived viruses had been dormant for tens of thousands of years ...

And it exposes permafrost below to more heat so that layer, too, can begin thawing and releasing gases. In ice-rich soils, such as in Siberia, the ground may slump.

The Yamal Peninsula’s permafrost layer, a massive sheet of frozen earth extending up to 300 meters deep, is capped by an active layer that thaws and refreezes with the seasons.

Layers of methane gas sit trapped below permafrost in Arctic regions, but if they’re released, it could spell trouble for the rest of the world.

SCIENTISTS have discovered two 14,000-year-old mummified “puppies” with their fur still intact and food still in their ...

The permafrost in Switzerland's Alps is the warmest since records began, the Swiss Academy of Sciences announced Tuesday.

Permafrost is a layer of soil and rock that remains frozen for at least two consecutive years. It is found in polar regions and high-altitude areas, such as the Arctic, ...

Older permafrost layers may not contain such well-preserved specimens, Opel said, but there's probably ancient DNA to be found. "There is certainly more to come," Opel said.
