Sending Carbon Dioxide To Sea

By Wendy Heller, January 13, 2008 @ 02:00 AM (EST)

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. The authors say that the verification research would have to show that the mechanism is effective and environmentally safe and that any negative impacts were balanced by the positive effect of reducing greenhouse gases in the atmosphere.
