Researchers test geofertilizing
Results of a large-scale experiment in the Southern Ocean, which surrounds Antarctica, hint that scientists could engineer the world's oceans, according to Nature. But some experts say the effects of "geofertilizing" can be harmful. The procedure can be accomplished by stimulating the growth of algae, which consume carbon dioxide. This means oceans can then be immense sponges for carbon dioxide -- the culprit for rising global temperatures.
