First guidelines on attempts to manipulate the ocean put spotlight on geoengineering industry

AI Summary

New guidelines are drawing attention to efforts to manipulate ocean systems for carbon removal, an emerging geoengineering industry. Supporters say ocean carbon removal may help counter climate change, while critics argue that further research is needed; one project is operating in Halifax harbour, Nova Scotia.

Proponents argue ocean carbon removal is necessary to counteract the effects of the climate crisis but critics say more research is needed A cluster of candy cane-striped smoke stacks dots the horizon of Tufts Cove in Nova Scotia, Canada. Deep in the briny depths of Halifax harbour, something huge is happening: the ocean is being engineered to remove atmospheric carbon. “This is what Mother Nature has done naturally for a few billion years in order to rebalance the atmospheric and ocean chemistry over long timescales,” says Dr Greg Rau, co-founder and senior scientist at Planetary Technologies.
