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.

Is this still true?

China seems to be winning now. And lead in solar, and robots.
