It's a bad argument to do nothing, but it's also not completely wrong. At this point we could turn off Europe and the USA and would still blow past 800ppm CO2 by 2100.
I think we overestimate how much is proxy emissions even now. Those are whole modern growing societies not just factories for us. Our view of climate change and carbon emission tends to be, like other things, very Euro-and-US centric and provincial.
What I’m saying is that if you turned us off you’d only delay the oncoming train, not stop it.
Also, cheap gas.
Probably helps California politically that 90% of it's natural gas is imported. vs locally produced coal. But Texas as reactionary conservative as it is isn't dragging it's feet either. (We hate that woke solar and wind. Enough to not make some money? Now you shut your mouth)
Worth noting inland western states are small population wise.
