Sea ice in the Bering Sea shrank to its lowest levels in recorded history in 2018, profoundly affecting northwest Alaska residents who depend on marine resources for food, cash and culture, according to a new peer-reviewed study. “This is an extreme event with immediate and long-lasting repercussions. It’s indicative of very rapid change in the […]
“If this were an annual health check-up, I think we’d have to say that the Arctic is chronically sick and getting worse.” In addition to warning that “the feedback to accelerating climate change may already be underway,” the U.S. government’s latest report on conditions in the Arctic reveals that temperatures in the region are persistently warming, […]
Increasing ground temperatures in the Arctic are indicators of global climate change, but until recently, areas of cold permafrost were thought to be relatively immune to severe impacts. A new study by Antoni Lewkowicz, a professor in the Department of Geography, Environment and Geomatics at the University of Ottawa and published in the journal […]
[dropcap]T[/dropcap]emperatures in the Arctic are rising twice as fast as in the rest of the world, causing permafrost soils to thaw. Permafrost peatlands are biogeochemical hot spots in the Arctic as they store vast amounts of carbon. Permafrost thaw could release part of these long-term immobile carbon stocks as the greenhouse gases carbon dioxide (CO2) […]
