Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In practice, this means that permafrost occurs at a mean annual temperature of 0 °C (32.0 °F) or below. In the coldest regions, the depth of continuous permafrost can exceed 1,400 m (4,600 ft). [22]

Sep 9, 2022 · The circumpolar permafrost and ground ice data contribute to a unified international data set that depicts the distribution and properties of permafrost and ground ice in the Northern Hemisphere (20°N to 90°N). The re-gridded data set shows discontinuous, sporadic, or isolated permafrost boundaries.

Different places have different amounts of permafrost. It may only occur in patches, or it may cover a large area. The colors on this map show different amounts of permafrost in areas of the Northern Hemisphere. Widespread melting of permafrost is one sign of global warming.
