El Nino is causing warmer and drier conditions in the Arctic, leading to record warm falls in Northern communities and challenging traditional hunting and trapping due to delayed ice formation.
In the much-higher water temperatures that lingered in the 2014-19 period, juvenile chum salmon metabolism was super-charged, meaning they needed more food, said the study, by scientists with the National Oceanic and Atmospheric Administration and the Alaska Department of Fish and Game. But the food that was available was of low quality — things like jellyfish instead of the fatpacked krill and other prey they normally eat, the study said.
Researchers are studying arctic ground squirrels, whose unique hibernation abilities may offer insights into treating human brain injuries and diseases.
The world surpassed the 2-degree warming threshold for the first time, signaling an urgent need to address greenhouse gas emissions as climate impacts worsen.
Alaska communities are facing significant challenges due to climate change, including the disappearance of snow crabs, threats to subsistence hunting and fishing, and difficulties in processing and storing food, but some communities are taking action and developing local climate adaptation plans with the support of funding and collaboration between different governments and agencies.
More than 100 dolphins have died in the Brazilian Amazon rainforest in the past week as the region grapples with a severe drought, and many more could die soon if water temperatures remain high, experts say.
A U.S. Energy Department climate scientist visited Utqiaġvik to evaluate research progress on permafrost and climate change, highlighting the importance of accurate measurements and models in predicting future climate patterns in the Arctic.
Researchers say climate change is playing a big role in the collapse, which has left thousands of people along the river without the salmon they depend on.
