Climatic features and statistical evaluation of climate change in permafrost regions in the north of Western Siberia
The relevance of the research is related to the necessity to assess climate changes affecting the permafrost due to the possible growth of greenhouse gas emissions and increase of accident rate in industrial, oil and gas infrastructure at permafrost thawing. The aim of the research is to estimate th...
