Iron seeding was tried--not a good idea.
Yes, it had the predicted effects in terms of plankton growth and the rest of the food chain. It did take a lot of CO2 out of the air. However, some of the animal life fell into the deep ocean and slowly decayed--releasing methane. Methane is a far worse greenhouse gas than CO2. Lots of fish but no climate benefit.
- i_am_nomad 7y agoI’d need a source for this, because this seems incorrect. Most of the captured carbon would enter a food cycle, and while some of it might become methane, much more of it would be constantly cycled in the ecosystem, and some would end up as calcium carbonate.
- LorenPechtel 7y agoMost is--it's just the amount that escapes as methane produces as much greenhouse effect as the CO2 that was removed.
