Good news is it takes a long time to get out of the Paris Climate Agreement, and the final step is after the next election.
Countries can't withdraw until three years after the Paris Agreement went into effect.
The Paris Agreement entered into force on November 4, 2016; so this means the US would have to stay with it until November 2019. After that, the rules mandate a one-year notice period, which would mean a withdrawal in late 2020; after the next presidential election on November 3, 2020.
Today, the Paris Climate Agreement is polling at over 70% in favor with voters (indicating Republicans are split on it, with Democrats and Independents strongly in favor), and well over 50% in favor among the whole US population. This will be a campaign issue in 2020, and Trump has set himself and his party up to be on the wrong side of it.
Yeah, yeah. And Hillary was going to win in a landslide also.
