Mathematicians team up with geophysicists to improve models that predict changes in sea ice
Dartmouth researchers are using computational mathematics and machine learning to develop models that better predict sea ice thickness in regions of the Arctic......»»
Sea ice"s cooling power is waning faster than its area of extent, new study finds
As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research led by University of Michigan scientists......»»
The salmon diaries: Life before and after Klamath Dam removal

Accepting uncertainty in sustainable fisheries is essential in a rapidly changing Arctic, says researcher
Climate change is making it almost impossible to decide how much, where and what to sustainably fish as the fate of future fisheries is becoming increasingly uncertain. This is leading to a slow process or inaction in adapting fisheries and their man.....»»
Hatcheries can boost wild salmon numbers but reduce diversity, research shows
The ability of salmon hatcheries to increase wild salmon abundance may come at the cost of reduced diversity among wild salmon, according to a new University of Alaska Fairbanks–led study......»»
Investigating variation in the permafrost active layer over the Tibetan Plateau from 1980 to 2020
The Tibetan Plateau hosts the world's largest permafrost region in the middle and low latitudes. Compared to the high-latitude Arctic permafrost, the permafrost here is thinner, warmer, and more sensitive to global warming. The active layer is a cruc.....»»
Canadian wildfire smoke dispersal worsened by coincident cyclones, study suggests
Wildfires are unplanned and unpredictable threats to Earth; while we may intuitively relate them to extreme heat at lower latitudes, they are known to occur in Arctic regions, such as those recently ravaging Russia......»»
The detection of a massive harmful algal bloom in the Arctic prompts real-time advisories to western Alaskan communities
In the summer of 2022, a research cruise detected a massive harmful algal bloom (HAB) in the Bering Strait region of western Alaska. This expedition provided a dramatic example of science utilizing new technology to track a neurotoxic HAB, and effect.....»»
Beryl sets off alarm bells among hurricane experts
