But impact of the air pollution is the warming!

No it's not. The CO2 and methane that causes warming doesn't have effects on health (at least at current levels), and conversely smog actually cools the local area by blocking sunlight rather than warming it.
The CO2 is the pollution in the air. The effect it has on health is warming the planet. Even the US Government will tell you this!
