Sending Carbon Dioxide To Sea
As the discussion of global warming becomes more serious, there is more talk about options for dealing with the carbon dioxide already in the atmosphere. Some people say we could store millions of tons of carbon in the ocean if we encourage the growth of microscopic marine plants by “fertilizing” the water with dissolved iron. A perspective in the journal Science states that the idea is intriguing, but it would require solid verification before it entered the market for carbon credits.
