I'd throw the issue over to DARPA and see if a more advanced solution is possible. Maybe we have giant solar powered aircraft combing the skies collecting CO2 and breaking it down to carbon. Or build a laser that zaps the stuff, lasers are cool, everyone loves lasers whether your gay, straight, right, left, or just don't give AF - you still love lasers. I don't know if the science behind any of that is feasible, but we have done a lot of stuff as humans that wasn't viewed as feasible at some point. And, it gets rid of Republicans main complaint of impacting the economy. Of course this would require funding, but it could be packaged into a nice shiny defense bill.

It's better than our "solution" of not good enough incremental progress on reduction and not good enough incremental increases in renewable energy. Neither of those baby steps deal with the amount of CO2 already in the atmosphere.
