Wether a country joins or leaves the Paris accord is irrelevant in the long run.  Countries that rely on the introduction of new energy sources because they are less expensive will be far ahead of those who waste trillions for the sake of participating in the eco-cult. Research this: the vast bulk of GWG reduction is caused by things that save money, like replacing coal with NG, insulating buildings, switching to energy-efficient vehicles and appliances, etc. But...the vast sums spent spent on"renewables" are responsible for generating less than 5% of global energy.
