Chances are, he will do more harm than good. This field does not have great track record. See, for example, the introduction of the Cane Toad to Australia: https://en.wikipedia.org/wiki/Cane_toad#Australia

I was unaware that cane toads, in any number, could have any effect on climate.

"...and that is how we know the earth to be banana-shaped..."

I just don't understand why everyone refuses to study the results (at least, from what the article seems to convey). Yeah, it was short-sighted and illegal and probably dangerous in ways that are currently inexplicable -- but isn't that the whole point? Go ahead and arrest the guy, or sue him, whatever -- but scientists should not pass up the opportunity to study the effects of an actual geoengineering intervention.

I am not a marine biologist, but is it possible that there is a different substance (maybe something artificial) that could be dumped instead of iron to encourage algae blooms without the associated toxicity? Obviously that would raise the cost. Or maybe iron + substance X to suppress the formation of toxic blooms?

Maybe there is some sort of trade off point here. Where the C02 reduction saves more wildlife than what ends up getting killed off by the toxic blooms?

Or at least add the iron more gradually.

It's not the iron that's toxic, but the oxygen depletion and other toxins expelled from the algae.

They could be using iron dust because it's cheaply available as a byproduct of something else, but I would have expected e.g. silica dust to be cheaper still.

[EDIT:] thanks for the info! TFA went on and on, yet somehow omitted the explanation for iron...
