Understanding Permafrost and Its Global Distribution Permafrost, a layer of soil that remains frozen year-round, covers an impressive 24% of the Northern Hemisphere. It stretches across wide swaths of ...

On the surface of the permafrost lies the so-called active layer, which thaws in summer and allows plants to grow: grasslands, forests, or wetlands with ponds and lakes. In some areas, the landscape ...

What is Permafrost? Permafrost is a fascinating geological phenomenon, consisting of ground that remains frozen for at least ...

Yet at this cliff, called Duvanny Yar, the Kolyma had chewed through and exposed what lies beneath: a layer of frozen ground, or permafrost, that is hundreds of feet deep—and warming fast.

“It’s fast and dramatic, affecting landscapes in unprecedented ways,” Turetsky said. Permafrost, a perpetually frozen layer under the ground surface, contains rocks, soil, sand and, in some cases, ...

Lachenbruch was an expert in permafrost, the rock-like layer of frozen soil just below the thin, insulated cover of soil and vegetation. In December 1970, he released a study in which he explained ...

A study has found that as climate change causes the Arctic permafrost to melt, pathogens may awaken and damage crops. The ...

Thanks to climate change, thawing permafrost in the Canadian Arctic has revealed the buried remnant of a glacier that’s 770,000 years old.

But researchers warned that other pathogens hidden in permafrost could turn out to be harmful to humans. "We are addressing this issue by sequencing the DNA that is present in those layers," said ...

Researchers have made an incredible discovery in the Canadian Arctic: the remains of an ancient glacier that could be more ...
