TOMSK, May 22 – RIA Tomsk. Employees of the "BioGeoClim" laboratory of Tomsk State University (TSU) made a documentary entitled "Dynamics of Landscapes of a Typical Yamal Tundra" about natural changes in the Russian Arctic that are occur due to global climate change, the university’s press service said on Friday.

Earlier it was reported that employees of the "BioGeoClim" laboratory, within the framework of the grant supported by the Russian Science Foundation, are studying the significance of climate change in the territories of the Arctic and subarctic regions of Russia. Climatologists also study the contribution of rivers and lakes in Western Siberia to global warming, the effects of permafrost thawing, and other climatic phenomena.

"The scientists of the TSU "BioGeoClim" laboratory made a film about how landscapes of the Russian Arctic are changing. The main reason for these processes – is the warming that began in the 80s of the last century and is growing rapidly today. According to scientists, the transformation of landscapes in the near future will have an increasing impact on the life of indigenous peoples and the development of the natural resources of the Arctic", – reports the press service.

It is added that the "Dynamics of Landscapes of a Typical Yamal Tundra" film is based on filming materials carried out by scientists during expeditions to the North in the summer of 2019 and open-source satellite images of different times. The starting point for the shooting was the village of Syo-Yaha, located at the confluence of the eponymous river in the Gulf of Ob, which is called the "Gateway of the Arctic."

It is specified that the territory of the Arctic serves as an indicator of the transformations occurring on the planet due to climate change, since the landscapes of the North are changing extremely quickly. These changes are reflected in the film.

"The processes that take place in the Arctic are natural, but climate warming ... accelerated them greatly. All this is amplified by an anthropogenic factor... We found green oases in places where builders used to take sand for new facilities. The broken permafrost began to melt and to give the soil elements of mineral nutrition that were in deep layers. As a result, vegetation that was not characteristic of the tundra appeared there", – the laboratory employee Sergey Loyko is quoted.

Scientists of the "BioGeoClim" laboratory suggest that 2020, with its abnormal temperatures, will be a serious blow to permafrost. During the new field season and the expedition to the Arctic zone of the Russian Federation, TSU researchers will test their hypothesis.
