It's crazy because while the US is one of the biggest emitters per capita, it's also home of the brightest minds and have by far the most efficient research ad development capacity. So US govt. denial is a huge hit in our already tiny chances to save the planet from hell in the next 50yrs.
A lot of the "brightest minds" are, and have always been, immigrants.
Guess who is the main target of a purge in the US now.
Maybe step down from that ultra high horse a bit and smell the proverbial coffee - let say we do a public vote, I would trust say population of Switzerland 100000000x more than US one on any decent vote. Chinese will take over US in those aspects you write, if they already haven't done so.
US population voted trump, lets not forget that. We (rest of the world, >95% of mankind) will never forget that, and the fact that he still has >5% support tells everybody all they need to know about current US and what to expect from it in future. All that says more than any wishful thinking that feels good and fuzzy warm inside.
Is this still true?
China seems to be winning now. And lead in solar, and robots.
The brightest minds in STEM are often loudly, proudly, confidently wrong on every single thing except their narrow specialty in STEM.
Many of the people still rejecting climate change are scientists and engineers whose egos make them obligate contrarians.
