Abstract
The remote sensing results of the dynamics of thermokarst lake areas are presented. The study is carried out for 29 test sites in the permafrost zone of Western Siberia and covers 35 years. It shows a trend toward a decrease in the areas of thermokarst lakes during the period under study. The time series of climatic variables (temperature and precipitation), received from reanalysis, are analyzed. It is found that an increase in the annual average temperature is accompanied by a reduction in the areas of thermokarst lakes located in the permafrost zone of Western Siberia.
