Drainage network response to Arctic warming
Rapid Arctic warming may increase erosion and stream channel formation, which alters the flux of sediments, carbon, and nutrients in these sensitive ecosystems. Yet, understanding landscape change is hampered by a lack of predictive tools applicable to permafrost settings. Background…

Cruise Ship Runs Aground in Greenland As reported by AP News on September 14, the Danish Joint Arctic Command announced that the luxury cruise ship MV Ocean Explorer was successfully freed after it ran aground in Greenland on September 11. The ship, with 206 people on…
Rounding the curve
Both Arctic and Antarctic sea ice appear to be heading toward their respective seasonal limits, reaching the lowest extent at the end of summer in the north, and the highest extent as winter ends in the south. In the Antarctic,…
The Arctic This Week Take Five: Week of 21 August, 2023
Canadian North Faces Its Worst Fire Season As reported by Al Jazeera on August 23, Canada is experiencing its worst fire season on record. According to the Canadian Forest Fire Centre, there have been 5,881 fires recorded so far, with 1,036 fires currently…
Arctic warming by abundant fine sea salt aerosols from blowing snow
Abstract The Arctic warms nearly four times faster than the global average, and aerosols play an increasingly important role in Arctic climate change. In the Arctic, sea salt is a major aerosol component in terms of mass concentration during winter…
Late summer heat wave avoids central Arctic
While the first half of August saw a rapid pace of Arctic sea ice loss, the pace slowed during the latter half of the month as mostly cooler conditions set in. Antarctic sea ice extent increased during the second half of the month….
What Would Greenland’s Independence Mean for the Arctic?
Climate change is fueling geopolitical competition in the Arctic. An independent Greenland could play an important role in years to come.
Arctic river channels changing due to climate change
Migration pace of large rivers in permafrost regions. A team of international researchers monitoring the impact of climate change on large rivers in Arctic Canada and Alaska determined that, as the region is sharply warming up, its rivers are not…
Scientists say deepening Arctic snowpack drives greenhouse gas emissions
Insulating effect of deeper snow is thawing ancient carbon permafrost reserves. Human-caused climate change is shortening the snow cover period in the Arctic. But according to new research led by Earth system scientists at the University of California, Irvine, some…
