GCOS Essential Climate Variables (ECV)

Terrestial/ECV T7 - Permafrost and Seasonally-Frozen Ground

Decadal changes in permafrost temperatures and depth of seasonal freezing/thawing are reliable indicators of climate change in high latitude and mountain regions. Warming may result in a reduction in the extent of permafrost and can have an impact on terrain stability and moisture and gas fluxes. Like glaciers, mountain permafrost and seasonally-frozen ground can also provide a significant contribution to summer water availability. Standardized in situ measurements are essential, both to calibrate and to verify regional and global climate change. (from the FAO/GTOS web site)
