Here, they developed a method to accurately map infrastructure and permafrost thaw risk called High-resolution Arctic Built Infrastructure and Terrain Analysis Tool (HABITAT). The model uses machine ...

But not all permafrost warms up in the same way. Most Arctic permafrost is slowly thawing—affecting only centimeters of surface permafrost—but Turetsky’s team estimates that about 20% of the Arctic is ...

The Arctic permafrost thaw is hazardous to the livelihood, safety, health, food security, and the infrastructure of communities living in Arctic regions, an international group of scientists have ...

The Batagaika crater in eastern Siberia, half a mile wide and growing, is the largest of many across the Arctic. As permafrost laced with buried ice thaws, the ground collapses, forming craters or ...

The vast frozen terrain of Arctic permafrost thawed several times in North America within the past 1 million years when the world's climate was not much warmer than today, researchers from the United ...

As soil a couple of feet deep goes from frozen to mush, the release of carbon could push climate change to a tipping point, writer Craig Welch reports in “Arctic permafrost is thawing fast.

For thousands of years, the shrubby landscape of the Arctic tundra stored carbon, but wildfires and thawing permafrost mean that this region is now releasing more carbon than it stores ...

As a result, the Arctic is critical for the homeland defense mission as well as power projection. However, increased wildfire, permafrost thaw, coastal erosion, and loss of sea ice are leading to ...
