  • Chemoautotrophic carbon fixation is vital for evaluating permafrost carbon-climate feedback, but has been largely ignored. Here the authors find that dark carbon fixation predominates ~1/3 of the investigated thermokarst lakes on the Tibetan Plateau.

  • The response of the phosphorus (P) cycle to permafrost thaw is unknown, but has implications for carbon dynamics. This study assesses changes in the P cycle upon abrupt thaw and shows accelerated soil P cycling and increased plant uptake, which may boost primary production and partially offset soil carbon loss.

  • Understanding microbial responses to climate warming is crucial for projecting permafrost carbon-climate feedback. Here, the authors reveal dual microbial roles in promoting both soil carbon release and stable soil carbon accrual under warming scenario.

  • Research on permafrost microbial communities is crucial for predicting the response of permafrost ecosystems to climate change. Here, Kang et al. provide insights into the structure and functional potential of permafrost microbial communities by analyzing 16S rRNA gene sequence data and metagenomic data obtained from an ∼1000 km transect on the Tibetan Plateau.

  • The response of CO2 release from soils to warming is enhanced at thermokarst sites due to the lower soil substrate quality and higher microorganism abundance than non-thermokarst locations, according to in situ warming experiments at an upland thermokarst on the Tibetan Plateau.

  • Soil nitrogen availability may alter carbon dynamics after permafrost thaw, but experimental evidence for this carbon-nitrogen interaction is still lacking. Here the authors show that elevated post-thaw nitrogen availability inhibits soil carbon release through its enhancement in microbial metabolic efficiency.

  • Massive stores of carbon and nutrients in permafrost could be released by global warming. Here the authors show that though warming across the Tibetan alpine permafrost region accelerates nitrogen liberation, contrary to expectations the elevated nutrients do not alleviate plant nitrogen limitation.
