Let me just add that The Ahnold would have been perfectly fine if he would have left "climate change" out of his diatribe. The greenhouse gases that impact the climate are not related to air pollution. The climate scientists agree with that because air pollution actually self-corrects through rainfall, etc., in a process called sinking. It doesn't linger in the troposphere in the way that carbon dioxide does. If Arnold wanted to be honest, he would have made the distinction. Pollution isn't a greenhouse gas that is linked to climate change.
