More needs to be done to better understand rapidly changing Arctic landscapes that are sinking as climate-driven permafrost thaw penetrates deeper, according to new research by University of Alaska Fairbanks scientists and others. International climate monitoring organizations have no uniform standard for measuring ground subsidence, leading to an underestimation of thaw depth and therefore an […]
EAGLE — As the late evening sunshine poured in from the northwest, a dozen residents of Alaska’s farthest upstream town on the Yukon River watched their winter race past in floating chunks of ice. Eaten into by the warm air of spring, the Yukon River’s solid sheets were breaking into smaller pieces. The big river […]
Thawing Arctic hillsides release a significant amount of organic carbon that has been locked in frozen ground for thousands of years but which now can contribute to an already warming climate, according to new research. The finding comes from the study of hillsides in a far north region of Russia, where the researchers also found […]
More areas of year-round unfrozen ground have begun dotting Interior and Northwest Alaska and will continue to increase in extent due to climate change, according to new research by University of Alaska Fairbanks Geophysical Institute scientists. The scientists said the spread of taliks — volumes of unfrozen ground within areas of permafrost — has major […]
