A long-feared scenario in which global warming causes Arctic permafrost to melt and release enough methane—a potent greenhouse gas–to accelerate warming and cause catastrophe probably won’t happen. That is the conclusion of a study appearing in the journal Science that began more than 20 years ago as a query posed by Jeff Severinghaus, a geoscientist at the Scripps Institution […]

Credit: Ted Schuur Rising temperatures in the tundra of northern latitudes could affect microbial communities in ways likely to increase their production of the greenhouse gases methane and carbon dioxide, a new study of experimentally warmed Alaskan soil suggests. The […]
Bacteria play a major role in cleaning up oil spills and mitigating its environmental impacts. A new review examines the major limiting factors for microbial degradation in Arctic environments. New economic developments in the Arctic, such as trans-Arctic shipping and oil exploitation, will bring along unprecedented risks of marine oil spills. The world is therefore […]
New economic developments in the Arctic, such as trans-Arctic shipping and oil exploitation, will bring along unprecedented risks of marine oil spills. The world is therefore calling for a thorough understanding of the resilience and “self-cleaning” capacity of Arctic ecosystems to recover from oil spills. Although numerous efforts are put into cleaning up large oil […]
