This map show’s the world’s most ice-rich and most climate-sensitive type of permafrost: Yedoma Permafrost. This permafrost has been permanently frozen since the last Ice Age.

Bringing together more than 25 researchers and their decades of permafrost expertise to produce this map was a tremendous multi-year journey, and is an important step towards understanding how Yedoma Permafrost and the massive organic content it has preserved since the last ice age may contribute to future greenhouse gas concentrations in the atmosphere once the area begins to thaw.
