Southern Ocean Carbon Sink Change
Riccardo Pravettoni, UNEP/GRID-Arendal
The Southern Oceans are recognised as an important carbon sink currently taking up approximately 15% of anthropogenic CO2. Models predict that as the atmospheric concentration of CO2 increases, so should the ocean’s absorbtive capacity. This seems to be happening in most areas, but not so in the Southern Ocean, which is observed to have a declining ability to absorb CO2.
