The release of mercury from permafrost “could take a huge toll on the environment and the health of those living in these areas,” said a co-author of the new study. A study published Thursday in Environmental Research Letters warns that Arctic warming could unleash toxic mercury currently contained in rapidly thawing permafrost, potentially threatening the region’s food supply and […]
New research has connected warming ocean temperatures to higher Pacific salmon abundance in the Canadian Arctic, an indicator that climate change is creating new corridors for the fish to expand their range. Salmon haven’t historically been seen in large numbers in the Arctic Ocean and its watersheds, but in recent years incidental catches by subsistence […]
As carbon dioxide accumulates in the atmosphere, the Earth will get hotter. But exactly how much warming will result from a certain increase in CO2 is under study. The relationship between CO2 and warming, known as climate sensitivity, determines what future we should expect as CO2 levels continue to climb. New research led by the […]
The Russian invasion of Ukraine is biasing predictions of how the Arctic will respond to climate change, according to a team of international scientists, including one from the University of Alaska Fairbanks. Their study, published Monday, January 22 in Nature Climate Change, compared the ability of Earth systems models to estimate the effects of climate change […]
