Mapping the Response of Permafrost in Canada to Climate Warming (Geological Survey of Canada, 1998)
Smith and Burgess present a GIS-based approach to map the thermal and physical response of Canadian permafrost to climate warming by integrating factors like snow cover, vegetation, organic layers, and soil properties. The study indicates that approximately 50% of current permafrost is warmer than -2°C and has the greatest potential for thaw and degradation under predicted air temperature increases of 4-7°C.
