Ocean Iron Fertilization's CO2 Removal Potential and Ecological Impact Evaluated

A new study in Nature by Technical University of Denmark researchers assessed ocean iron fertilization for CO2 removal. Simulations over 60 years in ten regions showed it could remove 0.14-0.70 billion tonnes of CO2 annually, with effectiveness and ecological impact varying by location. The Southern Ocean offered the best balance, highlighting the method's potential for climate mitigation but also its complex environmental considerations.
