Methane Seeps Out as Arctic Permafrost Starts to Resemble Swiss CheeseLeave a Comment
- Measurements over Canada’s Mackenzie River Basin suggest that thawing permafrost is starting to free greenhouse gases long trapped in oil and gas deposits.
- The conclusion of the authors: The warming climate triggers not only the natural production of biogenic methane, it can also lead to stronger emissions of fossil gas. This contributes significantly to the permafrost-carbon-climate feedback

- Study in the Mackenzie Delta in Canada shows high amount of geological methane emission
- The thawing permafrost soils in the Arctic regions might contribute to the greenhouse effect in two respects: on the one hand rising temperatures lead to higher microbial methane production close to the surface. On the other hand thawing subsurface opens increasingly pathways for old, geologic methane…
