Fertilizing the Oceans with Iron Sinks Carbon, But is it a Good Idea?

It’s a controversial idea that has been around for decades. Stimulate the growth of phytoplankton (plant plankton) in remote reaches of the oceans by fertilizing the oceans with iron. Previous studies concluded that such an approach would not be effective. However, the recent analysis of a 2004 ocean fertilization experiment in the Southern Ocean — [...]
