The fact that the US shifted their pollution away from something that causes obvious to anyone issues like acid rain to something that is more easily deniable makes it easy to deny climate change. The hole in the ozone layer stopped growing as well. Maybe it will take that level of problems to start in the US again for changes to happen??

Why not? China has/had the problem in their own backyard and we're likely acutely aware of the impact it has. Wouldn't that hasten their need to come up with alternative solutions?

Meanwhile the US is full of hubris and can't see beyond their own nose.

There was already an op-ed writer during Dubya's admin (remember when he was the dumbest president?) writing how their denial and non-investment in green tech was going to lead to China to be leaders in that space.

Sigh, without the Brooks Brothers "riot", the guy people insulted for talking about climate change would've been president...
