Geoengineering - Ocean Seeding

geoengineering projects that are or ideas that have been investigated as a way to try and sequester huge amounts of carbon dioxide from the atmosphere which is something we've delayed acting on for so long. David: "We're actually doing research into sort of smaller scale less perhaps less planetary ambitious but at the same time less risky potential interventions" He says it will never be a large scale planetary thing but for example when we have an area like the Great Barrier Reef where we can just tweak the temperature enough to avoid a bleaching event then that could be a useful tool in the future. We've got a question about clownfish. Chris, what do you think?
