Warming induced by the hypothesized greenhouse effect will have profound consequences for permafrost distribution throughout the high‐latitude regions of the globe. Two scenarios of climate change based on the palaeo‐reconstruction method widely employed by Russian scientists were used in conjunction with a model that produces zonal maps of permafrost distribution. Changes associated with both 1.2°C and 2.0°C warming of the mean global temperature are amplified in the high latitudes, which results in the potential for a large reduction of the area underlain by continuous permafrost. Thermokarst development is likely to be particularly acute in the West Siberian plain, where the climate model suggests that conditions will become marginal for the maintenance of permafrost. Le réchauffement hypothétique qui serait dǔ à l'effet de serre aurait des conséquences considérables sur la distribution du pergélisol dans les régions de haute latitude. Deux scénarios des changements climatiques réalisés par la méthode de paléoreconstruction largement utilisée par les scientifiques russes ont été employés, en měme temps qu'un modèle qui produit des cartes zonales de la distribution du pergélisol. Les changements associés à des réchauffements de 1,2°C et de 2,0°C de la température moyenne, sont amplifiés aux hautes latitudes, ce qui va potentiellement entraǐner une réduction considérable de la surface où s'étend le pergélisol continu.
