Siberian Methane Emissions Double Every Decade as Warming Fuels Fires and Microbial Activity
Key Takeaways
- Study published in Science (Vol 393, Issue 6811, pp. 615-621, August 2026) reveals Siberian methane emissions have doubled each decade.
- Two main drivers: warming-induced wildfires and enhanced microbial methanogenesis in thawing permafrost.
- Feedback loop: fires accelerate permafrost thaw, which increases methane production, further warming the climate.
- Findings suggest current climate models may underestimate Arctic methane emissions.
