When I talk to warmist friends, I ask them questions like “What % of the atmosphere is CO2?” I have gotten some ridiculous answers! But I won’t give them the answer, I tell them to look on the internet. Next I ask them “What % of the CO2 is manmade?” I know they won’t believe me, so I make them look it up themselves. Most of them are quite surprised!
Just so one can visualize the amount of CO2 in the atmosphere,
think of the entire atmosphere of earth as a 5 gal bucket and drop one green pea into it.
There’s your visual.
