Do you believe that geoengineering efforts, like ocean fertilization processes, are valuable tactics that will reduce global warming?

An international team of scientists has published the results of a 2004 experiment to fertilize oceans with iron. The ocean fertilization was an effort to reduce the carbon at the water’s surface and potentially slow global warming. This type of geoengineering, or large-scale manipulation of the climate, has been controversial, but this is the first experiment to show that the technique works.
