Ocean carbon cycle
Riccardo Pravettoni, UNEP/GRID-Arendal
Without the contribution of oceans and coastal ecosystems to global biological carbon
sequestration today’s CO2 concentration in the atmosphere would be much larger than
it is. But the uptake capacity of oceans and coasts is both finite and vulnerable. Minimisation
of pressures, restoration and sustainable use are management options that can help
these ecosystems maintain their important carbon management function.
