Permafrost is a layer of soil, rock, or sediment that remains frozen for at least two consecutive years. It occurs in polar regions, such as the Arctic and Antarctic, as well as in high-altitude mountain ranges. Permafrost plays a crucial role in shaping the landscape and ecosystem in these regions.

It is not so much that permafrost is good, as losing permafrost is bad. Permafrost keeps gases like carbon dioxide trapped within its frozen depths; when permafrost thaws, that gas is released, exacerbating global warming. Further, permafrost develops its own ecosystem which is destroyed when the permafrost is destroyed through thawing. The loss of all permafrost would mean the extinction of a lot of species.
Yes, permafrost underlies all of Siberia to some extent.
