I have listened to about half of the Trump/Musk audio. Musk says at some point, there could be so much CO2 in the air that it becomes hard to breathe. But I haven’t heard Musk say what he would do about China’s air pollution. Maybe that is in the second half.
I’ve heard his position on global worming before. He says it may be fake, but it’s best to take steps to mitigate it, in case there’s something to it.
