Since the possibility of reducing global warming by spraying iron into the Antarctic Ocean was proposed, iron-spraying experiments have been conducted 13 times in these marine areas, and the scientific verification of the hypothesis of iron limitations in the production of marine phytoplankton has made progress. Many of the results obtained suggest that the CO2 absorption effect in the oceans due to the spraying of iron is less than first expected, but there are plans by venture companies to spray iron and the building of an international management system is underway.
