Thermokarst lakes square dynamics of West Siberian continuousand discontinuous permafrost under impact of global warming

The issues of space sounding data application to problems of monitoring of Western Siberian permafrost in a context of climatic changes are considered. Thermocarst lakes are used as sensitive geocryological indicator of the permafrost landscapes dynamics. The gathered collection of satellite images at different times (1973-2005) for the areas of continuous and island types of permafrost distribution has allowed to investigate frozen rocks dynamics under global warming impact at last decades. It was revealed, that summarized areas of thermokarst lakes in continuous permafrost zone are increased, but areas of lakes in discontinuous permafrost, on the contrary, are decreased.
