JUNEAU — Recognizing that Alaska is the United States’ ground zero for the impacts of climate change, Governor Bill Walker today signed Administrative Order 289 establishing the Alaska Climate Change Strategy and Climate Action for Alaska Leadership Team. The Strategy creates a flexible and long-lasting framework for Alaskans to build a strategic response to climate […]
On the North Slope of Alaska, snow is melting earlier in the spring and the snow-in date is happening later in the fall, according to a new study by Cooperative Institute for Research in Environmental Sciences (CIRES) and National Oceanic and Atmospheric Administration (NOAA) researchers. Atmospheric dynamics and sea ice conditions are behind this lengthening […]
A University of Alaska Fairbanks study looking at the physics of tidewater glaciers has yielded new insights into what drives their retreat-and-advance cycles and the role that climate plays in these cycles. Lead author and UAF geophysics doctoral student Douglas Brinkerhoff said the study in Nature Communications reveals that shifting sediments drive the cycles among […]
Arctic winter warming events – winter days where temperatures peak above 14 degrees Fahrenheit (minus 10 degrees Celsius) – are a normal part of the climate over the ice-covered Arctic Ocean. But new research by an international team that includes NASA scientists finds these events are becoming more frequent and lasting longer than they did […]
