If you dropped loads of tiny expanded polystyrene beads into the sea, these would reflect sunlight. In the Arctic they could also act like a 'raft' for snow to build up on. They could be made on big ships that dropped them into the sea at points where they were unlikely to be blown away, and could float around for many years in the open ocean before bio-degrading and/or sinking to the bottom of the sea.
An alternative method would be to pour an oily liquid into the oceans that reflects sunlight. It would have to be gas-permeable to allow oxygen through. I do not know of such a liquid. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "geoengineering" group.
