We would have solved the global warming problem by the mid 1990’s.
I think if you look at a breakdown in sources of CO2 emissions, it's less than half. Yes, that's a lot, but it's not the whole story.
I'm 100% for getting off fossil fuels. I drive electric. But the transition is a hell of a lot more complex than "build a lot of nuclear power plants."
The US produced (and produces) lots of oil. It would probably have been enough (or close enough) to make the US entirely independent of OPEC oil.
The two proposed solutions were: military (the road taken), very expensive research (not really taken). I added a third one (nuclear) because it was cheaper and it wouldn't have needed much research. It was a known solution that would have gotten the US most (likely all) of the way towards energy independence and it would have reduced CO2 emissions a lot.
Though, obviously, no research lives in a vacuum. Companies profit from universities and the larger educational system, from other researchers laying the groundwork over the years etc.

We need time and more people looking at the issue = money.
