Where is the most common place for permafrost?

The Short Answer: Permafrost is any ground that remains completely frozen—32°F (0°C) or colder—for at least two years straight. These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles.

Is the permafrost in Siberia discontinuous or continuous?

Continuous permafrost extends under all surfaces except large bodies of water in the area. The part of Russia known as Siberia has continuous permafrost. Discontinuous permafrost is broken up into separate areas. Some permafrost, in the shadow of a mountain or thick vegetation, stays all year.

How is the southern limit of permafrost determined?

Warm permafrost degrades from both the top and bottom, increasing the extent of talik formation. The southern limit of permafrost moves northward in an irregular pattern, and is governed by localized factors that include {tooltip}peatland{end-link}Peat is an accumulation of partially decayed vegetation matter.

How is the melting of the permafrost affecting the environment?

1 Abrupt melting of the permafrost layer is leading to erosion, landslides and craters in the Arctic landscape. 2 As the permafrost melts, greenhouse gases are released into the environment. 3 Current climate change forecasts may underestimate the emissions from permafrost because they only take into account gradual thawing of the ice layer.
