Three recent papers authored by Ted Schuur, Regents' professor of biological sciences at Northern Arizona University, and other researchers around the world, organized through the Permafrost Carbon Network, investigate the biological processes taking place in the warming Arctic tundra and provide insight into what we can expect from that region as the climate continues to change. The world's most northern ecosystems, including the northern circumpolar permafrost region, are an important storage reservoir of organic carbon. Although this region, which includes the tundra and much of the boreal forest, contains only 15% of Earth's soil area, it stores around one-third of...
