I guess partisanship blinds even otherwise intelligent people to logic and makes them repeat nonsense.

The climate "cares" about cumulative emissions. On that score the US is by far the leader. https://ourworldindata.org/grapher/cumulative-co-emissions It's not even close.

Pretend China is 20 countries. Each country now has lower emissions than the US. Anyone can play that stupid game. Give up the games, think about solutions. China is working hard. Are we?

Climate doesn't care about political borders either.

But per capita is more informative when thinking about policy for curbing emissions, which is how we actually change our effect on the climate.

The rest of the world produces more than china. Checkmate.
