October 16 News: Geoengineering Experiment Spawns Massive Plankton Bloom

A controversial American businessman dumped around 100 tonnes of iron sulphate into the Pacific Ocean as part of a geoengineering scheme off the west coast of Canada in July, a Guardian investigation can reveal. [Guardian]

Satellite images appear to confirm the claim by Californian Russ George that the iron has spawned an artificial plankton bloom as large as 10,000 square kilometres. The intention is for the plankton to absorb carbon dioxide and then sink to the ocean bed — a geoengineering technique known as ocean fertilisation that he hopes will net lucrative carbon credits.

“It is difficult if not impossible to detect and describe important effects that we know might occur months or years later,” said John Cullen , an oceanographer at Dalhousie University. “Some possible effects, such as deep-water oxygen depletion and alteration of distant food webs, should rule out ocean manipulation. History is full of examples of ecological manipulations that backfired.”

Shifts in crop production reflect a view among food producers that this summer’s drought in the U.S. — the worst in half a century — isn’t a random disaster. It’s a glimpse of a future altered by climate change that will affect worldwide production. [Businessweek]
