  • The climatic impact of ancient carbon released during the thawing of Arctic permafrost depends on the degree to which it is degraded. Here, the authors show that permafrost-sourced carbon is preferentially metabolized by microbial communities during transit in high-latitude rivers.

  • In the Arctic, the risks of the permafrost thaw are perceived differently by communities, and key hazards include infrastructure failure, mobility disruption, decreased water quality and food security, and exposure to diseases, according to a transdisciplinary analysis based on workshops and a thematic network approach.

  • Using a global database of the radiocarbon content of rivers combining new and published measurements, isotopic mass balance suggests that about 60% of river CO2 emissions are derived from millennial or older carbon sources.

  • The release of ancient carbon from thawing permafrost is thought to have an important impact on global biogeochemistry through positive feedbacks. Here Dean and colleagues show that in Siberian permafrost, warming could liberate more contemporary carbon relative to aged counterparts.
