You still haven't gotten this straight, because you continue to discuss the individual parts of the whole cycle as if they were independent!
I'll try one more time to communicate with you on this topic.
First, my definition of surface water:
surface water = ocean water (e.g., sea water) and non-ocean water (e.g., lake water) on the surface of the earth.
It is a fact that the CO2 ppm (i.e., parts per million) in surface water is not uniform over the surface of the earth. Generally the CO2 ppm in ocean water is greater than the CO2 ppm in non-ocean water.
If rain washes so much CO2 out of the atmosphere I would think the opposite should be true, don't you?

Also, the CO2 ppm is not uniform throughout the earth's oceans. Also, the CO2 ppm is not uniform throughout the earth's non-ocean water.
Yes, that is true and it tends to put a crimp in your argument when you claim the cooling in a region can prevent GLOBAL warming. This was pointed out to you quite some time ago.

When water evaporates from surface water it forms a water vapor mix of H2O, CO2, and other molecules that were originally contained in the surface water. The warmer is a region of surface water, the greater the rate of that evaporation, and therefore the greater is the rate of CO2 ppm increase in the atmosphere over that region of the surface.
Here you start to have problems. The warmer a region is the greater the evaporation rate but the warmer a region is the LESS CO2 the water can hold. The more water vapor in the air the lower the CO2 partial pressure is. In hotter air with higher water saturation, the CO2 partial pressure is reduced.
SO now we start to see the problems with your claim.
Hotter air is less dense.
Water saturated air is less dense.
Warm water holds less CO2
Air at the height that rain clouds form is less dense
Water takes on CO2 based on Henry's law which says lower partial pressure of CO2 means water has less CO2.

Atmospheric winds subsequently spread these vapor mixtures throughout the many regions of the atmosphere. When sufficient relatively cold air blows through a region, the water vapor in that region condenses into clouds and/or rain. When water vapor condenses into rain, H2O and CO2 molecules mixed in that vapor enters surface water.
I guess if you ignore Henry's law. Lets assume water is evaporated at the surface at 80 degrees F (75% humidity, 29.92 inches Hg) and then rises to 5000 feet and forms clouds at 60F. (100% humidity, calculates to 24.9 inches Hg) This would mean according to Henry's law that the water at the surface would hold more CO2 since it has a higher partial pressure. The water droplets in a cloud would quickly reach their CO2 saturation point since there is a lot of surface area relative to the amount of water. What this would mean is that the water would evaporate and Henry's law would move more CO2 into the atmosphere to keep the surface water at saturation. The water would condense in the upper atmosphere but not capture as much CO2 as was released because of Henry's law. The rain would come down and then because of Henry's law the surface water would absorb the CO2 to reach saturation again.

So on the one hand, earth warming causes more CO2 to be in the atmosphere. On the other hand, earth warming causes more CO2 to be precipitated out of the atmosphere by rains, because there is more CO2 in the atmosphere. Net, if when the earth warms, there is more CO2 in the atmosphere and less CO2 in surface water than when the earth cools.
Only if you completely ignore Henry's law. More CO2 in the atmosphere STILL requires that Henry's law be followed.
Quote:
If no additional CO2 were to be inserted into the atmosphere, almost all of it currently in the atmosphere would eventually mix with water vapor and precipitate into surface water.
Bull ****. Henry's law is one of diminishing returns. As you reduce the amount of CO2 then Henry's law says that water will hold less and less CO2. But you completely ignore the fact that precipitation becomes surface water and the water MUST be evaporated to return to the atmosphere. And you just said I only discuss individual part and ignore the whole cycle.
