Permanently frozen ground, or permafrost, is a relic of the last ice ages. The temperature of these soils is below freezing point for at least two consecutive years—regardless of whether they ...

Permafrost — the permanently frozen ground that underlies much of the Arctic land surface — is thawing in many parts of the Arctic. [1] As permafrost thaws, it releases the powerful greenhouse gas ...

Permanently frozen ground, or permafrost, is a relic of the last ice ages. The temperature of these soils is below freezing point for at least two consecutive years – regardless of whether they ...

But now that human-induced climate change is making soils warmer, the thawing season is growing longer and the permanently ...

Permafrost, which is permanently frozen ground, and the active layer above it, which thaws during warmer months, are sensitive indicators of environmental changes. Recent research has focused on ...

Climate change is causing the permanently frozen soil, known as permafrost, that underpins much of the Arctic to thaw, which leads to destabilizing the ground layers above. The process is called ...
