They went full retard on politics and decided climate change isn't a thing. Or if it is, it is someone else's problem. "Look at the huge emissions of China and India - nevermind the CO2/Capita numbers that makes us the bad guy".
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.
