> Now, the new study would seem to suggest that humans may already be engaging in a kind of inadvertent iron fertilization campaign. But whether it’s having any significant effect on marine ecosystems or carbon storage is still unknown. But, since we know we're increasing atmospheric carbon, we do know that any increased carbon storage stemming from this accidental fertilization effect is dwarfed by our carbon output elsewhere, right? To the degree that carbon and aerosol iron are released from an overlapping set of activities, perhaps this study reveals a modest change in the coefficient relating emitted carbon to atmospheric carbon.
