Draining peatlands gives global rise to greenhouse laughing-gas emissions -- ScienceDaily - 0 views

Luciano Ferrer on 01 Apr 18"Drained fertile peatlands around the globe are hotspots for the atmospheric emission of laughing-gas -- a powerful greenhouse gas called nitrous oxide, which is partly responsible for global warming and destruction of the ozone layer, a new study shows. Research into natural peatlands such as fens, swamps and bogs, as well as drained peatlands, found that either draining wet soils or irrigating well drained soils boosts the emission of nitrous oxide significantly. Led by researchers at the University of Birmingham and the University of Tartu, Estonia, the study took in 58 peatland sites around the world. These included locations in the United States, Australia, Brazil, South America, Australia, New Zealand, East Africa, Southeast Asia, Siberia and Europe."
