At the moment it seems that the CO2 problem is more pressing and of greater magnitude than the problem of nuclear waste. It sounds like a relevant tradeoff.

Nuclear waste, as far as I have been learning, is pretty "safe". Yeah, you need a place to deal with it, but it's mostly highly shielded solids.

A video I watched recently explaining a lot: https://www.youtube.com/watch?v=4aUODXeAM-k

Yes, logically I agree. I'd rather the species sees another millenium to deal with this, than "go extinct" before.

Yet that is half the reason for the drama. The other half being Fukushima and Chernobyl.

Humans are not rational beings, hence we need to look at where their fear comes from, to find appropriate solutions.
