Permafrost stores tremendous amounts of organic matter.

Increasing temperatures will result in the release of additional

greenhouse gases, which will in turn accelerate climate-warming.

The Global Terrestrial Network for Permafrost (GTN-P) provides

systematic long-term measure- ments of permafrost temperature and active layer thickness (ALT), and is part of the Global Climate Observing System (GCOS).

The map shows todays permafrost temperature at 314 out of 1300 boreholes that contain data.

Generally permafrost temperature is increasing north to south, but are affected by site-specific conditions such as snow depth, vegetation and soil properties.
