Iron versus climate change
Metal deposits can promote the growth of ocean algae that gobble greenhouse gas

In 2004, a team of scientists traveled by ship to an enormous whirlpool in the ocean near Antarctica. Their goal was to find out if a risky strategy for fighting climate change might work. The plan: Dump iron in the water to trigger the growth of organisms called algae. Then let the algae soak up carbon dioxide, a gas that contributes to global warming. Finally, watch to see if the organisms drift to the seafloor.
This iron fertilization of algae appears to have been successful, an intern...
