Pollution From Asia Affects US Climate

At best useless, at worst a deliberately tendentious metric. Might as well measure it by hair length.

Sure, the PER PERSON pollutant output of countries like India and China is low; they have BILLION(s) of people living essentially like pre-industrial primitives.

Let's use CO2, since you like that metric, but instead of using raw population numbers, let's take at OUTPUT: PPP.

US CO2 5.7 bill (tons/yr), China CO2 3.4 US PPP: $11 trillion. China PPP $7 trillion On that basis they're basically the same.

If we compare per-capita income - since you want to consider that whole population figure more proportionally: US citizens have a PPP income of $43K. China's is $7K. At that same proportion, China's pollution output should be barely 1 bill ton/yr - or in other words, they are putting out more than 3.5 TIMES more pollution per $1 that goes into their citizen's pockets, than the US.

What were you saying again about the US being the "worst in the world"?

If you want to dig deeper you're missing another crucial point, that also explains the PPP:CO2 imbalance.

A significant proportion of Chinese emissions are related to the manufacture of goods which are directly exported to the USA. That is to say, as American manufacturing capacity has declined over the last 50 years, the CO2 production has been outsourced to China. This explains the CO2:PPP imbalance as the majority of the manufactured goods/wealth are immediately exported back to America.
