The supposed effects of carbon dioxide in relation to “global warming” are miniscule at best, and are absolutely swamped when comparing the effects of water vapor to that of carbon dioxide.
The rather specious theory put forth, is that the presence of carbon dioxide somehow retains heat received from solar radiation. Well, spoiler alert. The ability of carbon dioxide to retain heat is almost exactly the same as that of water vapor, a much more abundant atmospheric gas, so if a culprit is to be indicted, it would be water vapor. After all, there is from 30 times to 200 times as much water vapor in the atmosphere at any given time, as there is carbon dioxide. Also, carbon dioxide is very much higher molecular weight than the predominant atmospheric gases (nitrogen and oxygen), and would not rise very high into the atmosphere. Water vapor, on the other hand, is only about half the molecular weight of the predominant components, and rises (literally) to stratospheric heights, forming the cirrus clouds, wispy trails of very tiny ice crystals. Carbon dioxide is just not a very big player in any mechanism of heat retention in the atmosphere.
I’ve been pondering this myself within the last week, and not taking the time to calculate the molecular weight of Carbon Dioxide vs atmospheric gases, my general hypothesis nearly mirrored your own.
You do realize of course that at some point, you and I too become filthy CO2 emitters worthy of destruction so the planet will not die.
Cows are already in the bulls-eye.
