Tendencies in the variability of climatic values in permafrost zone of Western Siberia in the XXI century
In the framework of the study, we investigate spatiotemporal variability of the main climatic variables in the Arctic part of the territory of Western Siberia at the end of the XXth and beginning of the XXIst centuries, as well as their trends until the year of 2100 using the method of mathematical...

Thus, according to the estimates of mathematical modeling methods, by the end of the XXIst century, the air temperature, as well as the soil temperature, will continue to grow, which, in turn, will lead to an increase in the depth of the seasonal thawing layer and a shift in the boundary of the permafrost zone to the north.
