sorry- that should have read 3.4% of 0.04% = 0.00136%
Some have the estimate of man’s release of CO2 up to 3.8- but most sites state it’s around 3.4%
[[EPA document supports ~3% of atmospheric carbon dioxide is attributable to human sources]]
[[Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth’s atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.]]

There are several sites that give very similar numbers- even the IPCC statements are close to these figure I believe- No matter which figures you use- the Bottom line is that man’s release of CO2 is so ridiculously small that there is no way it can affect global climate- There is no thick blanket of CO2 covering the earth preventing CO2 from leaving and ca causing catastrophic warming
What little does get absorbed by CO2 released by man is such a small figure that it almost instantly reaches equilibrium the moment it gets radiated out- it is so small that it is instantly overwhelmed by the massive amount of cooler atmosphere- Very much like dumping 4 5 gallon pails of water of 100degree water into an olympic sized pool of 95 degree water would instantly nearly reach equilibrium because it is overwhelmed by the massive volume of cooler pool water
man’s respionsibility amounts to 3.4% (Being generous) of the TOTAL amount of all greenhosue gases and CO2- naqtural and manmade- that amount is 0.04%
3.4% of 0.04% = 0.00136% of the atmosphere is CO2 due to man
