Popis: Iron minerals trap carbon in permafrost, preventing microbial degradation and release to the atmosphere as CO2, but the stability of this carbon as permafrost thaws is unclear. Here the authors use nanoscale analyses to show that thaw conditions stimulate Fe-reducing bacteria that trigger carbon release.
