Type: article
Abstract: Prognostic estimates of changes in the climatological boundary of the permafrost zone as a function of the average annual air temperature on the territory of the Bolshezemelskaya tundra under various scenarios of the development of the world economy until the middle of the XXI century have been obtained. It is shown that the shift of the climatological boundary of permafrost, determined by the threshold value of the average annual air temperature, in the north-eastern direction observed in the period from 1950 to 2010, according to the adjusted scenario forecasts, obtained using a climate model, will continue in the coming decades under any scenario of the development of the world economy and is an inevitable consequence of anthropogenic influence on the climate. The results of the study are important for assessing the prospects and development of a network of long-term observations, which is being created to monitor the state of permafrost and greenhouse gas fluxes in the Russian Federation.
