Permafrost has been warming in the last decade at rates up to 0.39 C 10 year-1, raising public concerns about the local and global impacts, such as methane emission. We used satellite data on atmospheric methane concentrations to retrieve information about methane emission in permafrost and non-permafrost environments in Siberia with different biogeochemical conditions in river valleys, thermokarst lakes, wetlands, and lowlands. We evaluated the statistical links with air temperature, precipitation, depth of seasonal thawing, and freezing and developed a statistical model.

This article describes the diversity of Russia’s Arctic cities. As a group, Russia’s northern urban agglomerations are larger than those found in the West. But there is enormous diversity among them that makes the region one of the most dynamic in the Russian Federation.
