Wot?
Higher CO2 levels have a NEGATIVE effect on water vapor in the atmosphere?
Somebody is talking out their rectal orfices once again. Really COLD weather decreases the relative humidity of air, as well as the absolute amount of water vapor as a part of the atmosphere. But really cold weather also increases the uptake of CO2 by water, and holds the CO2 as carbonic acid, until warmed again.
Really hot weather INCREASES the relative humidity of the air, in the presence of an evaporative source, and also the capacity of the atmosphere to HOLD a much higher absolute quantity of water vapor. Simultaneously, the warmer water RELEASES its CO2 content, as carbonic acid disassociates, and as a released gas coming out of solution, evaporates from any body of water in which it has been held.
Now, if there is no evaporative source to carry water vapor into the atmosphere, the relative humidity falls to extremely low levels, as the absolute quantity of water vapor is reduced. Water vapor, as a gas, is LIGHTER than the mixture of N2 and O2 that makes some 98+% of the atmosphere, while CO2 is HEAVIER, and tends to settle in lower parts of the atmosphere. Why do plants get so stunted and sparse at high altitude? Not because of lack of water, but because of lack of a very basic building block for growth, CO2.
Somebody tell me what I have wrong here. And somebody please, PLEASE, why this pile of balderdash is supposed to change that previously held conception. Cause and effect seem to be entirely transposed, because the right questions are NOT being asked.
