Extensive ground temperature measurements complicate our understanding of how vegetation cover, snow duration, and microtopography influence the pace of permafrost thaw in a changing climate.
New, detailed surveys from the Beaufort Sea reveal a seafloor depression the size of a city block associated with permafrost thaw and likely influenced by the movement of groundwater below.
Hydrogeological properties of degrading permafrost come to fruition with a new 3-D modeling study that highlights the increasing role of groundwater in the water cycle of high-latitude areas.
Increasing incidents of wildfires in the Arctic are not only thawing permafrost but changing the entire underlying structure of the region.
Arctic warming may release less carbon dioxide from high latitude lakes but increase their climate impact by releasing more methane.
Permafrost thaw is a major threat to pipelines in the Russian Arctic, particularly those carrying natural gas.
Passive seismic data from a station atop Germany’s highest peak reveal a 15-year record of permafrost degradation, suggesting that this technique could be used for long-term environmental monitoring.
New research finds that Arctic rivers currently transport limited permafrost-derived dissolved organic carbon, which has implications for understanding the region’s changing carbon cycle—and its potential to accelerate climate change.
When permafrost thaw reaches concentrations of ice underneath the surface, it may trigger local soil instability.
In the works for more than a decade, proposed legislation to protect glacial and permafrost environments in Chile suffers from uncertainties and omissions that could sow conflict instead of solutions.
