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

TL;DR - A Nature study uses a process-rich global biogeochemical model to examine how ocean iron fertilization trades off carbon dioxide removal against ecological harm across ten ocean biomes.

• Compares carbon-removal efficiency among distinct ocean regions.
• Models ecosystem impacts alongside climate benefits rather than evaluating carbon uptake alone.
• Could inform where, or whether, ocean iron fertilization warrants further consideration.
• The provided abstract does not report quantitative results or identify optimal biomes.
