Climate benefit and ecological cost trade-offs for ocean iron fertilization.

Ocean iron fertilization (OIF) is being discussed as a potential carbon dioxide removal (CDR) strategy 1 .

Ocean iron fertilization (OIF) is being discussed as a potential carbon dioxide removal (CDR) strategy 1 . Yet the trade-offs between climate benefits and ecological costs remain poorly understood 2-4 . Here we use a process-rich ocean biogeochemical model with validated…
