There are some deep issues within the USA, it appears the USA is at war with itself, between it's citizens. Putting America first is a fight that has forced people onto warring sides of a debate that should never have been a debate.
Perhaps this was always inevitable. There is such misunderstanding of basic facts here that make it incredibly difficult for outsiders to understand how this kind of discussion is even possible. Be it climate change, flat earth, religious beliefs, governmental conspiracy, it all appears to originate from the same place.
The issue here seems to be a miscommunication of the economic benefits of renewable energy. It creates jobs, and lowers energy prices. However those jobs need educated people, and perhaps it is unskilled labourers who are not seeing the benefits.
The Paris accord was an entirely voluntary agreement, with no financial implication. It was about getting a head start on renewable energy whilst preventing climate change from getting any worse. Coal/Oil will dry up, whilst prices are pushed up in return. You need to transition from one to the other, and getting a head start offsets the economic disadvantage later. Pulling out of this agreement will remove American leadership, and lead other nations to produce those renewable sources of energy which the USA will be buying at an increased cost.
But arguing this appears to be pointless as reason and logic have been replaced by political ideals within the US. The world will carry on without America, but it is saddening how this can occur in a modern developed nation, the richest nation on earth.
