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 ...

Permafrost—ground that remains frozen year-round—is capped by a few feet of dirt and plant detritus. Called the active layer, this soil normally thaws each summer and refreezes in winter ...

The Frozen Ground Under Threat Permafrost is like Earth's ancient freezer, stretching over vast regions, mainly near the North and South Poles. It holds soil, rocks, and sub-zero water, remaining ...

According to this, the thawing of the permafrost would lower the water table and allow water to drain away more easily, causing the soil to dry out in the long term. MPI-M researcher Philipp de Vrese ...

"The most climate-stressed regions all contained permafrost, which is vulnerable to thaw as temperatures rise," researcher Sue Natali said.

A third of the Arctic is now emitting climate-changing greenhouse gasses after thousands of years of storing them, according ...

“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 ...

"In Sweden, permafrost lands are important as soil carbon reservoirs and for traditional land use practices, such as reindeer herding. Like in other regions of the Arctic, permafrost thaw is ...
