While at Science, I reported on research suggesting that seeding the ocean with carbon-capturing phytoplankton is no cure-all for global warming:
To help cool a warming world, some scientists have suggested fertilizing the oceans with iron. The idea is to stimulate vast blooms of phytoplankton, which sequester carbon dioxide. But such an approach could have deadly consequences. Experiments in the northern Pacific Ocean show that phytoplankton in waters far from land produce a molecule called domoic acid, a neurotoxin that has killed wildlife and people in coastal areas.
