Ocean Fertilization Experiment off Antartica Is Halted

An article in the Telegraph reports that a planned experiment to dump 20 tons of iron sulfate into the Southern Ocean to create a 186-square-mile plankton bloom to soak up the greenhouse gas carbon dioxide from the atmosphere has been stopped by the German government because of concerns that the experiment violates the UN’s Convention on Biodiversity. This should bring relief to environmentalists who have been worried that this large experiment could have resulted in an ecological disaster. The Polarstern, the German research ship carrying the iron, left South Africa with scientists on board from Germany, India, and the UK about two weeks ago. About one week later the experiment was placed on hold by the German government so that a group of international scientists could review it. It appears now that this global warming geoengineering experiment has been terminated before the review was completed.
