Thawing Permafrost Is Releasing Carbon, but Something Unexpected Happens
AI KEY TAKEAWAYS (TL;DR)
- Much of the ancient carbon released from thawing Arctic permafrost appears to end up trapped in seabed sediments rather than quickly returning to the atmosphere
- The Arctic’s frozen ground holds an enormous reservoir of organic carbon
- As permafrost thaws and coastlines erode, some of that carbon is carried into the ocean, where microorganisms can break [
