Bare peat surfaces created by frost action and wind erosion in permafrost peatlands have been shown to emit high amounts of nitrous oxide (N2O). With global warming, emissions of this highly potent greenhouse gas are expected to increase in Arctic permafrost peatlands. In natural unmanaged soils wit...
