Satellites pinpoint communities at risk of permafrost thaw

Thawing permafrost in the Arctic is already unleashing methane and carbon dioxide to the atmosphere, exacerbating global temperature rise. As well adding to the climate crisis, this ground, which has been frozen for thousands ...

Seismology: A promising tool for monitoring permafrost

The warming and thawing of permafrost in response to rising temperatures are increasingly destabilizing rock slopes, causing more occurrences of rockfall in recent years. This trend is expected to continue, raising concerns ...

Permafrost thaw could release bacteria and viruses

When considering the implications of thawing permafrost, our initial worries are likely to turn to the major issue of methane being released into the atmosphere and exacerbating global warming or issues for local communities ...

Permafrost: a ticking carbon time bomb

Sheltered by snow-spattered mountains, the Stordalen mire is a flat, marshy plateau, pockmarked with muddy puddles. A whiff of rotten eggs wafts through the fresh air.

Minimal evidence of permafrost carbon in Siberia's Kolyma River

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 ...
