Ancient Greenland methane release offers a warning for a warming Arctic
Key Takeaways
- Researchers linked large Melville Bay seafloor pockmarks to past methane hydrate release.
- The proposed trigger was glacial meltwater after the last glacial maximum.
- Methane hydrates hold vast carbon stores and can be destabilized when cold, high-pressure conditions change.
- The finding adds a new potential methane-release pathway to Arctic climate risk discussions.
