The damage from the melting of permafrost in the Arctic until 2050 is estimated at 7 trillion rubles
At the same time the degradation of permafrost soils is already the cause of 29% of losses arising from oil and gas production, porarctic.ru writes with reference to the statement of the head of the Department of Development of the Russian Arctic and the implementation of infrastructure projects of the Ministry of Regional Development Maxim Dankin.
The assessment of potential losses for industrial civil facilities in the Arctic has increased markedly. So, in 2021, the head of the Ministry of Natural Resources, Alexander Kozlov, said that by 2050 this damage could amount to five trillion rubles.
The deterioration of the forecast is a sign of the seriousness of the problem faced by both Arctic ecosystems and high–latitude settlements in Russia. The development of the cryolithozone warming processes is fraught with serious obstacles to the further development and economic use of the polar territories.
That is why it is necessary to deepen work in the direction of studying the nature and dynamics of temperature changes in the Far North.
This task will be partially solved with the launch of a system of state monitoring of the state of permafrost, the bill on which is under consideration by the State Duma of the Russian Federation.
But in addition to the organization of observation, in the future it will also be necessary to develop methods of effective counteraction to destructive processes occurring in the thickness of permafrost soils.
