A private company backed by a controversial U.S. businessman has unilaterally conducted the world's most significant geoengineering project to date. Russ George, in conjunction with a First Nations village on Haida Gwaii, has dumped around 100 tonnes of iron sulphate into the Pacific Ocean in a technique known as ocean fertilization. The experiment, which is in violation of two United Nations moratoria, has outraged environmental, legal, and civic groups.

The idea of doing this has been floating around for some time but nothing has been done beyond some small scale testing because the long term consequences are still uncertain. I'm not sure if Russ is an over eager environmentalist or a creative money grubber, but either way this is an awfully risky project, and probably illegal.
