Republicans are not against taking steps to help mitigate our impact on the environment. They simply want agreements to be fair, economically feasible, and have worthwhile expected results. Like most problems, I think Republicans expect technology to resolve most of the issues as it usually does. Perhaps we can evolve our technology without destroying industries that can positively serve the rest of the world that is still developing. Someone burning turds to cook on does not really care about reducing their CO2 footprint. They are more concerned with starving.
