Aurora scientist and interested-in-all-things guy Neal Brown contacted me to see if I had written about why power wires sometimes […]
Using statistically modeled maps drawn from satellite data and other sources, U.S. Geological Survey scientists have projected that the near-surface permafrost that presently underlies 38 percent of boreal and arctic Alaska would be reduced by 16 to 24 percent by the end of the 21st century under widely accepted climate scenarios. Permafrost declines are more […]
CHAMPAIGN, Ill. — A new analysis of fire activity in Alaska’s Yukon Flats finds that so many forest fires are occurring there that the area has become a net exporter of carbon to the atmosphere. This is worrisome, the researchers say, because arctic and subarctic boreal forests like those of the Yukon Flats contain roughly […]
Using a new net, marine biologists from the Alfred Wegener Institute have, for the first time, been able to catch polar cod directly beneath the Arctic sea ice with a trawl, allowing them to determine their large-scale distribution and origin. This information is of fundamental importance, as polar cod are a major source of food […]
