I had my doubts all along, and new science confirms. Adding iron to oceans is not the magic solution to excess CO2 and climate change.
So much for John Martin's famous quote "give me a half tanker of iron and I'll give you an ice age." He was right that iron can cause plankton blooms, but wrong about taking his results to geo-engineering.
"Ocean iron fertilization is simply no longer to be taken as a viable option for mitigation of the CO2 problem," says Hein de Baar, an oceanographer at the Royal Netherlands Institute for Sea Research in Texel.
