The risky idea of dumping iron into the ocean to promote plankton growth has been around for a long time. The reasoning: more algae blooms, more CO2 absorbed. But many scientists think that by the time the algae dies, rots, and release methane and nitrous oxide, it will worsen the greenhouse effect. Even most supporters think it should be studied before being tried. The IPCC is expected to dismiss this particular idea as speculative and probably counterproductive.
But Planktos corporation, backed by Silicon Salley, has decided to go full speed ahead experimenting with it -- to hell with possible side effects. They are simply going to dump iron into a 10,000 square kilometer patch in the GalÃ¡pagos -- one of the most delicate and important ecosystems on the planet.
