Water vapor accounts for 95% of the heat retention by “greenhouse gases.” 0.001% of atmospheric water vapor is from human activity.
Carbon dioxide accounts for 3.186% of the heat retention by “greenhouse gases.” 0.117% of atmospheric carbon dioxide is from human activity.
Methane accounts for 0.360% of the heat retention by ‘greenhouse gases.” 0.066% of atmospheric methane is from human activity.
If you include nitrous oxide, CFCs, and all other trace gases, 0.28% of heat retention by the atmosphere is due to human activity.
When you put it that way, what we’re attempting to do is to drop a nuke on a city to resolve a hangnail.
