A new international study finds that Arctic glacier retreat between 2000 and 2020 has unveiled over 1,500 miles of coastline—primarily in Greenland—potentially increasing coastal hazards and contributing to sea level rise.

UAF undergraduate Leanne Bulger discovered a persistent hole in a Fairbanks forest emitting unusually high CO₂ levels—likely due to thawing permafrost microbes—and led a team using probes, gas analyzers, and radar to study its depth and gas flux.

This article explains how Interior Alaska’s cold, airy snow uniquely bends off railings and loops from power lines, defying gravity due to slow deformation and the sintering process.

A new study from Kodiak’s NOAA Alaska Fisheries Science Center links ocean acidification to a significant decline in red king crab populations in the Bering Sea, challenging the view that warming is the primary stressor.

Warm Atlantic waters are rapidly reshaping the Siberian Arctic, sparking an era of unprecedented sea ice loss—something that will have ongoing implications for the region’s ecosystem and climate, says new research.

A new study reveals that climate change has shifted large parts of the Arctic from a carbon sink to a net carbon emitter, with up to 40% of tundra, boreal forests, and wetlands releasing more CO2 than they absorb.

The article explains how a severe decline in wild salmon, driven by climate change, is forcing Alaska mushers to abandon traditional subsistence feeding practices in favor of costly commercial dog food. This shift is altering both the practice and culture of dog mushing in the region.

A part of a pedestrian bridge collapsed onto the Seward Highway in Anchorage due to high winds, blocking the highway temporarily, though the bridge's main structure remained intact. No injuries were reported.

Mälarenergi in Västerås, Sweden, is testing carbon capture technology to reduce emissions from its waste-to-energy plant. This initiative could significantly decrease CO2 emissions, key for addressing climate challenges.
