I know exactly how co2 works. It's naturally produced and naturally cycled by plants, water, and dirt. Just like upper air above the oil/coal burning centers don't have higher co2 than the air over the ocean. co2 is not why LA is warmer.
It's going to get 15-20 degrees warmer, even if humans never produced a particle extra of co2.

We would have more animals overall, yes, but I do not think there would have been more cows without humans. They are protected from pretadors today by humans. The amount today is therefor a concern regarding methan emissions, and at the same time we make room for it by reducing CO2 absorbing trees and plants.
It is not local CO2 emissions and weather, like in LA, that is the problem. It is the global emissions and its feedback effects over the longer climate periods. And if it gets 20 degrees warmer or colder 20 thousands years from now, is irrelevant, don't you think?
