CO2 (carbon dioxide) are widely publicised but CH4 (methane) emissions are less known. These more potent methane emissions in the atmosphere are also caused by either natural or anthropogenic sources. When oxidised, CH4 leads to the formation of CO2 emissions in atmospheric ozone. Studies of land and water sources of emissions are more widely known….

Economic vs climate strategy face-off in the Russian Arctic
Russian climate doctrine and strategy include climate change as one of the biggest 21st century challenges especially socio-economic development of the Arctic region with both opportunities and risks (Drachkova et al., 2023, Kremlin, 2020). The Arctic is warming twice as fast as other areas with reduced snow cover, reduced permafrost, increased precipitation. Sea ice is…
A regulatory shhh across Arctic coastal ecosystems?
Alongside the Arctic Ocean, the Barents, White, Kara, Laptev, East Siberian and Chukchi seas are marine ecosystems including seabeds, ocean floor and subsoils. Increases in drilling of the continental shelf increases environmental impact. Yakovleva noted the most common issues are emissions, oil / oil product spills, pollution, waste (including metals, radioactive, plastic etc ), and…
What is lurking in Svalbard’s waters?
Researchers looked at marine biodiversity in Arctic waters near Svalbard, in particular the marine ecosystems in the Barents Sea and the Fram Strait region. In the lower benthic layers of the waters, there are greater biodiversity of e.g. zooplankton and fish species. There is a mix of warmer and saltier Atlantic water and colder Arctic…
Understanding climate politics in Central Asia – interview with Alina Bychkova
Alina Bychkova has nearly completed her PhD thesis ‘Understanding climate change narratives in Central Asia: science, politics and media discussions’ at Nottingham Trent University. She co-published ‘Kazakhstan’s climate change policy: reflecting national strength, green economy aspirations and international agenda’, Post-Communist Economies,34:7,894-915,DOI: 10.1080/14631377.2021.1943916 What is your PHD and how is it going? My PhD is in…
Great Norilsk Expedition results in 2023
In 2020, scientists from across 14 branches of the Russian Academy of Sciences began the expedition in Taymyr. They are assessing the state of Arctic ecosystems in the area. Early results of impacts on Arctic waters, via TASS and the Institute of Biophysics (EN) at the Siberian Branch of the Russian Academy of Sciences (SB-RAS);…
Digging deeper and deeper into the Lake Chany basin
Lake Chany in Western Siberia has historically been a shallow lake, approximately 2 metres deep and a 2.2 thousand km2 area. It is saline which is similar to other lakes in the region due to intensive evaporation after rain and run off. This theoretically increases the affect of climate change in water levels and surrounding…
Why do people move in, out and around Siberia?
Researchers looked at the ‘impact of environmental and anthropogenic factors on the migration of the rural Arctic population of Western Siberia’. They focused on the Yamal–Nenets Autonomous Okrug. They analysed long-term migration data collected from surveys and interviews between 2012 and 2021, Rosstat and other Russian databases including open-source platforms. Districts included Nadymsky, Yamalsky, Tazovsky,…
Less fizz, more plants – acids and eutrophication in Arctic lakes
Russian researchers identified acidification of lakes during 1990s in Murmansk, Karelia, Archangelsk and Vologda regions and found up to 5% of lakes have acidification due to human causes in humid areas of European Russia and West Siberia. Nornickel was identified as the main contributor of sulphur dioxide SO2 in Kola and Norilsk areas. However since…
Black Kites on a flyway between Western Siberia and the Indian Subcontinent
The Black Kite (Milvus migrans) is a raptor found throughout Eurasia, Australia, Africa and can live in a range of habitats including human populated ones. Some species winter in West Asia and Africa and there are a range of research studies looking at their migration patterns, but the migration patterns from Siberia are mostly unknown….
