Here we use biogeochemical simulations to show that restoration of these marine ecosystems can also lead to permanent carbon dioxide removal by driving ocean alkalinity enhancement and atmosphere-to-ocean CO2 fluxes. Most notably, our findings sugg

Main Realistic trajectories that limit global average surface warming since the start of the industrial period to well below 2 °C require sustained atmospheric CO2 removal together with massive and rapid reductions in global CO2 emissions1. Natural modes of CO2 removal, such as afforestation/reforestation and restoration of coastal habitats, have received considerable attention as potential carbon capture approaches given that they can also provide notable economic and ecological co-benefits2,3. For instance, through efficient conversion of atmospheric CO2 to organic biomass followed by…
