Just not true. While global warming was not on the forefront of the political compass when the Clean Air Act was created, climate change was a scientific discussion.

Even at face value your claim is false, for CO2 concentrations above a certain level, in enclosed situations, is a health hazard and that was known at the time, but such circumstances were just not the purview of the Clean Air Act, for to intentionally raise the CO2 concentration within a closed facility (housing humans) would be addressed by criminal law (from manslaughter to murder.)
