Well, it turns out there's an extremely cheap solution to this that can sequester another 1/3rd of our carbon while making lots of plankton and restocking the oceans with fish. http://planetsave.com/2014/07/02/ocean-fertilization-dangerous-experiment-gone-right/ http://planetsave.com/2014/07/02/ocean-fertilization-dangero...

This is fascinating -- I wanted to ask if anyone knew of any geoengineering ideas to deal with rising ocean temperatures and acidity EDIT: The article mentions that "there are also concerns that trapping CO2 at the bottom of the ocean may increase ocean acidification" so I'm not sure if this particular approach is really a solution?

  Ocean fertilization is an idea discussed from oceanographers since the last twenty years at least.

According to the article, this might be an extremely cheap way of making the problem worse: > There are also concerns that trapping CO2 at the bottom of the ocean may increase ocean acidification ...However it certainly is interesting enough to warrant more research!

I'm really glad to see this. I don't know for sure that iron fertilization will turn out to be a good idea, but the opposition to experimenting with it baffles me. It's like people think that we can choose whether or not to engage in geoengineering. No, we can't: we're already doing it (as indeed the article points out). If we can find new interventions that counteract the effects of our existing interventions, that would be a wonderful thing. I think we should be experimenting with both iron fertilization (to sequester carbon and combat ocean acidification) and sulfur aerosols (for cooling). Both of these mimic natural events such as volcanic eruptions; they're not unprecedented in nature.

  I heartily welcome the opportunity to troll the chemtrail people when we do begin geoengineering experiments at scale, in earnest. I know there's going to be a conspiracy-theory movement around anything we do to save our planet.
