At least the most draconian laws in the nation have made the air over Los Angeles as pure as the driven snow! /sarc
Back when I was still working, I worked with a guy who was already looking at mean average global temperature and carbon emissions-before that was even a thing. He took annual worldwide crude oil and natural gas consumption and estimated the tons of CO2 that would be generated assuming 100% combustion. He then put a photo of an elephant on screen and said if the elephant is total annual CO2 emissions for the entire planet, only the tail would represent man made combustion of petroleum. Maybe the elephant has two tails now, but the analogy still works. I can’t remember if he included coal or not - too long ago.
And assuming 100% conversion of petroleum products covers all the energy to produce, process and distribute them too, not to mention any electricity generation from them.
He said the vast majority of CO2 comes from Mother Nature herself - largely from biomass in the oceans.
Compared to all the burning of stuff the rest of the world does the US contribution and impact on climate change is what????? The hairs on the elephant tail?
Is that worth wrecking our entire economy while the rest of the world laughs their asses off at our foolishness?
It is all political.
