  • Methane emission from thermokarst lakes in high-altitude permafrost regions is poorly understood. Here, authors explore the amount and origin of methane emissions and associated methanogenic microorganisms in thermokarst lakes on the Tibetan Plateau.

  • Methane emissions from aquatic systems contribute approximately half of global methane emissions, according to meta-analysis of natural, impacted and human-made aquatic ecosystems and indicating potential mitigation strategies to reduce emissions.

  • Analyses of inventory models under two climate change projection scenarios suggest that carbon emissions from abrupt thaw of permafrost through ground collapse, erosion and landslides could contribute significantly to the overall permafrost carbon balance.

  • Winter warming in the Arctic will increase the CO2 flux from soils. A pan-Arctic analysis shows a current loss of 1,662 TgC per year over the winter, exceeding estimated carbon uptake in the growing season; projections suggest a 17% increase under RCP 4.5 and a 41% increase under RCP 8.5 by 2100.

  • The sudden collapse of thawing soils in the Arctic might double the warming from greenhouse gases released from tundra, warn Merritt R. Turetsky and colleagues.

  • Future permafrost thaw may be underestimated unless effects of wildfire are considered. Here the authors show that wildfires in boreal permafrost peatlands influence soil temperature and seasonal thaw depth for several decades, and increase the rate of complete permafrost thaw along permafrost edges.
