‘Rogue’ Geoengineering Scheme
In Pacific Violated UN Rules, Groups Say
A project sponsored by a controversial U.S. businessman dumped about 100 tons of iron sulphate into the Pacific Ocean this summer, an experiment in geoengineering that environmental groups say violated international agreements, The Guardian has reported
. According to the report, satellite images appear
to confirm that the iron dumped from a fishing boat sponsored by Russ George, the former CEO of Plankton Inc., triggered a nearly 10,000-squre-kilometer plankton bloom off Canada’s west coast. Some researchers believe this technique could emerge as a critical strategy in reducing the effects of climate change since such blooms are capable of sucking carbon out of the atmosphere and ultimately trapping it deep in the ocean. The experiment took place west of the islands of Haida Gwaii, where George convinced the council of an indigenous village to approve the project. Critics say it should not have taken place without proper scientific assessment and violated existing UN resolutions. Scientists say it is unclear whether such iron fertilization damages ocean ecosystems, triggers toxic tides, or worsens the effects of ocean acidification. “History is full of examples of ecological manipulations that backfired,” said John Cullen, an oceanographer at Dalhousie University in Nova Scotia.
