Database of Ice-Rich Yedoma Permafrost Version 2 (IRYP v2)
Ice-rich permafrost in the circum-Arctic and sub-Arctic, such as late Pleistocene Yedoma, are especially prone to degradation due to climate change or human activity. When... -
Circumpolar raster grids of permafrost extent and geohazard potential for near-future climate scenarios
One of the consequences of warming climate is rising ground temperatures and degradation of perennially frozen ground, permafrost. Thawing of near-surface permafrost can cause... -
