EVOLUTION OF THE CRYOLITOZONE OF THE COASTAL MARINE REGION IN THE CONDITIONS OF A CHANGING CLIMATE
Abstract
An urgent problem is climate change and marine conditions affecting the formation and evolution of the permafrost zone of the shelf and the continental border of the Russian Arctic. The results of long-term monitoring of the permafrost zone clearly demonstrate the degradation of frozen rocks in both continental and subaquatic conditions of the western sector of the Russian Arctic. Against the background of the observed climate dynamics, the study of geoecological processes becomes especially relevant when drawing up long-term plans for the development of climate-dependent branches of economic activity. The coastal-marine region of Western Yamal is the most model and vulnerable area under climatic changes. Against the background of the observed climate dynamics, the study of geoecological processes becomes especially relevant when drawing up long-term plans for the development of climate-dependent branches of economic activity. Changes in climatic conditions affecting permafrost, sea hydrology, as well as the potential increase in negative anthropogenic pressures associated with growth, oil and gas production in the Arctic and the development of related infrastructure, sharply increase the level of geoecological risks. Climate warming and changing environmental conditions are changing the geo-ecological and land-use conditions. Climate change: affects the socio-economic activity of the regions, living conditions of people and public health; leads to changes in the natural environment and is reflected in the species composition of flora and fauna, river levels, weather conditions, seasonal rhythm, thawing of permafrost, the distribution of areas of natural focal diseases, etc.; may entail the creation of a fire hazard, the possibility of environmental disasters. Estimated climate change can have both positive and negative impacts.
