Arctic holds 1.3 trillion tonnes of ancient carbon, scientists find what warming does to it

A study of Arctic seabed sediments has offered new clues about the fate of ancient carbon released from thawing permafrost. Researchers found that microorganisms processed only a small fraction of the carbon into gases, while most remained buried offshore. The findings could refine estimates of permafrosts climate impact, although scientists caution that some carbon may decompose before reaching the seabed.
