Map Reveals Hot Spots for Arctic Greenhouse Gas Emissions
By bringing together data on permafrost stability, soils, and other Arctic conditions, scientists have plotted where permafrost is vulnerable to collapse, which could release long-stored carbon.

Permafrost Area Is Sensitive to Key Soil and Snow Physics
Accounting for key soil and snow variables shows a much higher impact on simulated permafrost area than uncertainties in land cover and climate data.
