When permafrost thaws

Nature Geoscience, Published online: 30 November 2020; doi:10.1038/s41561-020-00668-yThawing permafrost mobilizes concerning amounts of carbon into the wider environment. Piecing together carbon sources and sinks in this complex system is important to understanding its overall climate impact.

Carbon and nitrogen cycling in Yedoma permafrost controlled by microbial functional limitations

Nature Geoscience, Published online: 30 November 2020; doi:10.1038/s41561-020-00662-4Carbon dioxide emissions from permafrost thaw are substantially enhanced by relieving microbial functional limitations, according to incubation experiments on Yedoma permafrost.

Synergistic effects of four climate change drivers on terrestrial carbon cycling

Nature Geoscience, Published online: 23 November 2020; doi:10.1038/s41561-020-00657-1Increases in atmospheric CO2 can be dampened but also accelerated by the net impact on terrestrial carbon cycling of combined changes in temperature, rainfall, CO2 and nitrogen, according to an eight-year grassland experiment in the United States.

Coupled anaerobic methane oxidation and reductive arsenic mobilization in wetland soils

Nature Geoscience, Published online: 23 November 2020; doi:10.1038/s41561-020-00659-zThe coupling of anaerobic oxidation of methane and arsenate reduction is an important pathway of releasing arsenic from soils, according to incubation experiments of arsenate-contaminated wetland soils.
