He is governor of Ohio, which is technically a state, but I can't find a single mention of him pushing a policy to address climate change. I take this mostly as a convenient excuse not to do anything. Maybe as governor, he thinks the problem should be addressed by cities and counties? This goes back to what I just said about him not being very honest about his real positions. First of all, climate change is a world problem, that needs to be addressed by every nation and every level of government in coordination with each other, and suggesting that it's a state problem is a hair's-breadth from absurd. But second, I think he mostly says it shouldn't be a federal problem to stop the federal government from doing anything and deflecting accusations of being anti-science at the same time. I find this extremely cynical.
