Study Suggests Substantial Carbon Dioxide Release with Permafrost Thaw

Scientists who study Arctic ecosystems have forewarned a “sleeping giant” hidden within permafrost soils–trillions of tons of planet-warming greenhouse gases that will be released when rapid thaw awakens microbes, activating soil decomposition. Improving what is known about microbial community makeup and behavior in these fragile ecosystems could help determine how consequential rapid permafrost thaw will…
