Curtailing global warming with bioengineering? Iron fertilization won't work in much of Pacific

Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of the ocean's carbon-capturing algae -- algae need iron to grow -- but a new study shows that the excess iron had little to no effect.
