Then what’s the point you’re trying to make? Obviously, the if the percentage of one increases, the percentage of the other decreases, even if we add a bunch of tons of only CO2. But contrary to what you posted, no matter what we do, water vapor won’t compose 95 percent. If we add a bunch of tons of CO2 and raise CO2 content by 2 percent, then water vapor will be 93 percent. Because math, and you just said it. Then you said CO2 would still only be 3 percent.
PD, I’m sure that I’m with ya, but I do not comprehend what point your trying to make with this bit about percentages. I’m trying, but I can’t make sense of it. None of the rest of your post really requires this to make your point.
