On Yamal, buildings may collapse due to thawing of permafrost

As Yaroslav Kamnev, candidate of physical and mathematical sciences, stated, an increase in the depth of seasonal thawing

permafrost is guaranteed to affect the entireinfrastructure of the Yamal-Nenets Autonomous Okrug. Perhaps some buildings will lose stability, and some will begin to collapse. Linear objects such as roads and pipelines are especially susceptible to this. 

Kamnev said that, compared to 2016–2018for years, in 2020 the depth of permafrost thawing in Yamal increased. The expert is confident that in the future the permafrost will disappear completely, but it is not yet possible to say exactly when this will happen. 

One reason is the increase in average annual temperatures across the planet over the past 50 years.  In Arctic regions this effect is more pronounced. 

Scientists of the Yamalo-Nenets Autonomous Okrugcarefully monitor the dynamics of changes in the depth of the active layer. According to Kamnev, many thermometric wells have been installed in Yamal. In order to track the dynamics of changes in the depth of the active layer, the international CALM (Circumpolar Active Layer Monitoring) program was created.
