Abstract
The paper analyzes the current temperature state of frozen and thaw soils in the Baikal region (Olkhon Island). It has been demonstrated that the current trend in soil temperature is directly related to climate changes and to the increase in the atmospheric air temperature. Permafrost within Olkhon Island is significantly transformed: the processes in soils are aimed at the degradation of frozen strata.
