And they are mixing particulate pollution, which has no link to climate, but does have significant health impacts, with Co2, which they claim is the cause of global warming yet has zero impact on health.
They use the same trick to claim the USA has horrible pollution. Take away Co2 as a "pollutant" and the USA's air is cleaner than Norway, Netherlands, Denmark, Switzerland, France, Germany, etc. In fact, we have some of the cleanest air on earth. With only a few exceptions, the only countries with cleaner air are extremely remote island nations.
CO2 is plant food. The US makes enormous amounts of plant food. The Left -- you know, the people who are so worried about starvation in the Third World -- are really upset that we produce so much plant food.
