Estimated future permafrost change: 3 °C above preindustrial level

A globally applicable relationship between air temperature and permafrost areal fraction was derived using reanalysis air temperatures and the historical IPA permafrost map. This relationship defines a maximum, minimum and mean permafrost fraction at a given air temperature. Future air temperatures were estimated for a particular global mean warming, using the observed Arctic amplification and a pattern scaling.
