A team of ocean and climate researchers is calling for a new generation of carefully designed ocean iron fertilization (OIF) field trials to determine whether this marine carbon dioxide removal (mCDR) method can safely and effectively leverage a natural ocean process to pull the greenhouse gas carbon dioxide (CO2) out of the atmosphere. The paper, which is published in Dialogues on Climate Change, argues that larger, longer studies with rigorous monitoring and clear "go/no-go" safeguards are needed to accurately assess OIF as a potential long-term CO2 storage solution to help mitigate human-induced climate change.
