Warming effects of spring rainfall increase methane emissions from thawing permafrost: Site-level data from bog complex IV - Soil Temperatures 2014-2016
Methane emissions regulate the near-term global warming potential of permafrost thaw, particularly where loss of ice-rich permafrost converts forest and tundra into wetlands. Northern latitudes are expected to get warmer and wetter, and while there is consensus that warming will increase thaw and me...
