the way i figured the amount awhile back was greenhouse gases are 0.04% of atmosphere- man’s CO2 is just 3.6% of that 0.04% (might be a little higher now)
3.4% of 0.04% is 0.00136% - man’s CO2 is so minuscule that climate alarmists should be ashamed of suggesting it is causing climate change globally- it can’t even cause it locally- there’s nowhere near enough
Run the numbers again. Anthropogenic CO2 is well under 3.4% of total CO2.
