We did titration in chemistry where we counted the drops of one chemical in another and like on drop 389 the fluid was still clear and then on drop 390, it all turned red or some other color. So we both know that a tiny change can make for a tipping point that produces a large result.
But like you, when I heard the concentration of CO2 in the atmosphere and realized it was a TRACE gas, and that man has only produced some 4% of that minuscule trace gas, it didn’t take much reasoning to conclude it was not likely to be the tiny portion man adds to that trace gas that has been causing the warming.
Add that to the fact we have been in and out of ice ages without man producing any CO2, and you have to be either downright stupid or in denial to think Man has the capacity to change the earth’s temperature signficantly and permanently over time. It is the height of arrogance or stupidity.
With liberals, it is just a delicious lie they want to believe because mother Gaia is their religion and they want to see man, especially America, as the earth’s enemy.
From the first day I heard the CO2 theory, I knew we were in trouble. We’ve had success in reducing SO2 and NOx, so.... They expected the same success. The uninformed would think CO2 is no big deal.
It IS a big deal. The BIGGEST deal.
If the CO2 theory is correct, mankind is screwed.
Fortunately, I have never believed it. Nor do I know ANY engineers (in the US) that believe it.
Btw... That may be the best summary of my own reasoning that I have ever read! :-)
