The Arctic tundra, which has been a carbon sink for millennia, has shifted to become a carbon source.

The erosion that prompted Gov. Mike Dunleavy's action is advancing on the Northwest Alaska community's water lines.

Researchers believe that if permafrost thaw continues at its current rate and mercury keeps being released, it could pose a real threat to many communities throughout northern and western Alaska.

Permafrost Pathways started two years ago with the goal of mapping the permafrost thaw and putting that data into the hands of the communities themselves. As human-caused climate change continues to warm the region and the permafrost melts more and more, the project is expanding.

German scientists from Alfred Wegener Institute are using classic planes to map and document the accelerating permafrost thaw in Northwest Alaska.

Climate change is affecting all aspects of the northern housing industry, from the structures themselves to the transportation of materials. One way to fix the issue is to put more reliance on northern community-based knowledge..

A study finds that while permafrost thaw in the North is causing local and regional changes, it is not a global climate tipping point.

Rivers and streams in Alaska are changing color – from a clean, clear blue to a rusty orange – because of the toxic metals released by thawing permafrost, according to a new study.

Recent discoloration of 75 streams in Arctic Alaska reflects increased iron and trace metal loading following climate-driven permafrost thaw. These findings have considerable implications for drinking water supplies and subsistence fisheries.

The $100 million Pretty Rocks Bridge will cross the site of a landslide that has closed the road at Mile 45 since 2021.

Arctic rivers are undergoing significant changes due to a warming climate, with increased precipitation and permafrost thaw leading to stronger flows and altered chemical compositions.

The oranging of northern rivers seems to be related to recent permafrost thaw that has allowed streams to release previously captive iron, trace metals and acid.

Conservationists petition for federal protection of the rare Kigluaik buttercup, threatened by climate change and proposed mining activities.

NASA's PACE satellite, designed to study ocean biology in unprecedented detail, has been successfully launched to enhance understanding of Earth's changing climate and improve weather forecasting.

Climate change is causing a 'microbial awakening' in Alaska's ecosystems, altering food webs as fungi become a major energy source for small mammals.

Melting permafrost in Nunapitchuk is causing severe structural damage to homes, leading to erosion, instability, and health issues for residents.

Two local governments have retracted their criticism of Conoco's Willow project, now focusing on protecting subsistence resources and leveraging project opportunities.

The collapse of Diomede city's building, suspected to be caused by melting permafrost, has led to emergency measures and online schooling as efforts to stabilize and dismantle the structure proceed.

At the 2023 American Geophysical Union fall meeting, scientists from the University of Alaska Fairbanks (UAF) are showcasing their research. One highlighted study involves the Permafrost Grown initiative, which aims to help Alaska farmers manage permafrost-related challenges such as ground thawing that leads to uneven terrain and sinkholes. Benjamin Jones from UAF is using drones and pulsed lasers to analyze historical changes in agricultural land to develop best practices for sustainable farming on permafrost.

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.
