Ocean iron fertilization: balancing climate gains against ecological risks

A new study examines the trade-offs of ocean iron fertilization, a geoengineering method that aims to boost carbon absorption by stimulating phytoplankton growth. Researchers found that while it can help mitigate climate change, it risks significant ecological disruptions, such as harmful algal blooms and oxygen depletion. The findings highlight the need for careful assessment before deploying such large-scale interventions.
