I'm not against geoengineering, and it will be part of the actions that posterity will have to do in order to deal with climate change, but why leave the major changes in lifestyle that will be required to fight it for future generations? We must accept that we need to massively increase energy efficiency, and a huge part of that is abandoning the "everyone gets a car and a McMansion". We should not default to geoengineering. We should default to reduction of carbon pollution, obviously, then when it isn't enough, start geoengineering, which will probably also be necessary. The start with geoengineering faction is just a few steps away from the "it isn't happening" crowd.
