“all for a gas that has a zero point zero percentage in the earths atmosphere”
Actually, CO2 comprises about 0.04% of the atmosphere, but you’re close enough.
Yeah but see the liberal Marxist fascists always use “400 ppm” to make it sound a lot more than it actually is, so my thought is fine - two can play at that game. 0.04% is zero point zero four percent but why not just round it off- zero point zero. Methane is another one they always mention which is 0.00017% so you can imagine how I pronounce that ha ha . “Zero point zero zero zero percent”
