Regularities of the modern development of frozen ground near the southern boundary of permafrost against the background of a positive climate trend are considered. Criteria for the potential formation of permafrost in response to climate warming are established. Results of modeling and quantitative assessment of the newly formed permafrost caused by thaw subsidence and subsequent transformation of landforms are given with due account for soil drainage and warming effect of the snow cover.
Keywords: permafrost, thawing of frozen ground, freezing of thawed ground, changes in permafrost conditions, frozen ground thaw subsidence, relief inversion.
