“…There are tendencies of a significant growth or suppression of soil CO 2 fluxes across different types of human impacts, such as forest fires, trampling, settlements, reindeer grazing and clear cuts on cryogenic ecosystems in Russia (Karelin et al, 2017). For example, Ivakhov et al (2019) analysed CO 2 measurements during 2010-2017 and reported CO 2 concentration increases of 20 ppm in Tiksi at a coast of the Laptev Sea and of 15 ppm at the Cape Baranov station.…”

“…3.2) are dealing with atmospheric composition changes (Q4), key feedbacks between climate and air quality (Q5), and synoptic-scale weather (Q6). Recent results demonstrate improved quantification of the carbon balance and CO 2 fluxes and concentrations due to land use change, forest fires in Siberia, and new understanding of aerosol sources and properties in the Arctic environment and across northern Eurasia (Pulliainen et al, 2017;Karelin et al, 2017;Rakitin et al, 2018;Skorokhod et al, 2017;Alekseychik et al, 2017). However, most of the results deal with atmospheric aerosol chemistry and physics in boreal and Arctic environments originating from measurements in the few flagship stations in Finland and Russia (Kerminen et al, 2018;Wiedensohler et al, 2019;Freud et al, 2017;Östrom et al, 2017;Kalogridis et al, 2018;Bondur et al, 2016;Bondur and Ginzburg, 2016;Bondur et al, 2019c, d;Bondur and Gordo, 2018;Mikhailov et al, 2017;Breider et al, 2017), indicating the need for a comprehen-sive station network in the PEEX region.…”

Abstract. The Pan-Eurasian Experiment (PEEX) Science Plan, released in 2015, addressed a need for a holistic system understanding and outlined the most urgent research needs for the rapidly changing Arctic-boreal region. Air quality in China, together with the long-range transport of atmospheric pollutants, was also indicated as one of the most crucial topics of the research agenda. These two geographical regions, the northern Eurasian Arctic-boreal region and China, especially the megacities in China, were identified as a “PEEX region”. It is also important to recognize that the PEEX geographical region is an area where science-based policy actions would have significant impacts on the global climate. This paper summarizes results obtained during the last 5 years in the northern Eurasian region, together with recent observations of the air quality in the urban environments in China, in the context of the PEEX programme. The main regions of interest are the Russian Arctic, northern Eurasian boreal forests (Siberia) and peatlands, and the megacities in China. We frame our analysis against research themes introduced in the PEEX Science Plan in 2015. We summarize recent progress towards an enhanced holistic understanding of the land–atmosphere–ocean systems feedbacks. We conclude that although the scientific knowledge in these regions has increased, the new results are in many cases insufficient, and there are still gaps in our understanding of large-scale climate–Earth surface interactions and feedbacks. This arises from limitations in research infrastructures, especially the lack of coordinated, continuous and comprehensive in situ observations of the study region as well as integrative data analyses, hindering a comprehensive system analysis. The fast-changing environment and ecosystem changes driven by climate change, socio-economic activities like the China Silk Road Initiative, and the global trends like urbanization further complicate such analyses. We recognize new topics with an increasing importance in the near future, especially “the enhancing biological sequestration capacity of greenhouse gases into forests and soils to mitigate climate change” and the “socio-economic development to tackle air quality issues”.

“…The risk of catastrophic consequences for soils and soil cover, industrial facilities and social infrastructure associated with permafrost degradation increases sharply with increasing depth of seasonal thawing-freezing. The increase in the depth of seasonal soil thawing is associated with climate warming [11,14], with increasing thickness of snow cover as a heat insulating natural factor [6], with changes in the vegetation cover [15] and anthropogenic activities [16].…”

The paper summarizes the experience of studying the effect of modern warming on the thawing depth of sandy and loamy soils in the permafrost zone. The definition of soil cryogenesis as a natural process and facies as the end result of soil cryogenesis as a process is given. The effect of soil cryogenesis facies on stress corrosion cracking of gas pipes of the Gazprom system in cold and warm seasons has been studied. It was found that the facies of soil cryogenesis are interconnected by the process of energy and mass exchange. It is shown that in the annual cycle, each facies formed by soil cryogenesis is the basis for the development of stress corrosion cracking of gas pipelines.
