Strong geologic methane emissions from discontinuous terrestrial permafrost in the Mackenzie Delta, Canada | Scientific Reports

Our study suggests, first, that thinning permafrost in a warmer climate may not only result in the frequently reported and discussed increased emission of biogenic CH4, but also in increased emissions of geologic CH4, that is currently still trapped under thick, continuous permafrost, as new emission pathways open due to thawing permafrost.

Secondly, in other arctic regions with natural gas and oil reservoirs that are currently capped under mainly continuous permafrost, e.g. the North Slope of Alaska or Siberia10, CH4 contributions from those geologic sources might need to be included when addressing future CH4 emissions under ongoing permafrost thaw.

Thirdly, our results indicate that geologic CH4 emissions may contribute strongly to the permafrost-carbon-climate feedback, especially in permafrost areas vulnerable to thawing and therefore warrant much more attention.
