I’ve heard his position on global worming before. He says it may be fake, but it’s best to take steps to mitigate it, in case there’s something to it.
The good news is that he says that the amount of CO2 today is nowhere near the "critical" %. But if he believes the critical % may become real, and the amount of CO2 from China remains more than double what the US produces, he should say what would happen in that case. Would we fight a shooting war over emissions?
