The […]

A University of Queensland-led international study could lead to more accurate predictions or the rate of global warming from greenhouse gas emissions produced by thawing permafrost in the next 100 years. The study of the microorganisms involved in permafrost carbon degradation links changing microbial communities and biogeochemistry to the rise of greenhouse gas emissions. It […]
Animals the size of Labrador retrievers are changing the face of Alaska, creating new ponds visible from space. “These guys leave a mark,” UAF ecologist Ken Tape said of North America’s largest rodents, beavers. He has observed the recent work of beavers north of Arctic Circle using satellite images. He and a group of arctic […]
