Polar Oceans Carbon Storage Potential Requires Policy Shift

Polar oceans play a critical role in carbon storage and biodiversity, yet current scientific and policy frameworks remain unprepared to integrate them into climate strategies. A new review by the Horizon Europe project POMP emphasizes that while Arctic and Antarctic ecosystems capture significant carbon, they are increasingly threatened by warming and ice loss.

Researchers warn against treating polar blue carbon as a simple offset for fossil fuel emissions. The study calls for increased research investment and immediate protection of vulnerable habitats like salt marshes, kelp forests, and deep-sea sediments, despite remaining uncertainties regarding measurement and long-term sequestration.
