Ever had a beer or soft drink go flat? Know why that happens? The colder a liquid is the more dissolved gases it can hold. As it heats up, it becomes oversaturated, and releases gasses.
This is true whether it's a Corona, Pepsi, or water.

Science tells us 75% of the earth's CO2 is trapped in the oceans and other bodies of water.


If CO2 drove increases in temperature, instead of following it, at any time in the past when temperatures rose, it would heat bodies of water, which would release more CO2, which would increase temperatures, until a runaway event would happen until global temperatures and atmospheric CO2 levels were so high it would extinguish all life on the planet.
That we're here discussing these issues ssys it never happened and the henny pennys can be summarily dismantled is evident.

In the late 80s CO2 was a serious topic among top scientists. Then two converging lines of evidence ( not theory) made it a moot point. First was when and why agriculture began. And second was a serious of examination of geological history of atmospheric chemistry over time.

Agriculture became possible when Net Primary Productivity of cereal grains rose (due to higher CO2 as Oceans warmed) to where it was better to plant and harvest than be entirely nomadic - and being able to maintain and raise livestock due to much more productive grasslands. This led to an examination of the status of life overall - how much energy there really is in the biosphere and how's its harvested. It has declined significantly since the Carboniferous.

Second, and much more overwhelming, there are over 50 atmospheres of CO2 in rocks as carbonates and shale deposited since the Cambrian. One clear conclusion emerged from this - the Earth is dying - because outgassing including CO2 production has declined ( less volcanism) and weathering and carbon sinks are so much stronger - the atmosphere is going away faster than the sun can get brighter - hence we are colder. More importantly - CO2 is declining to a level soon (over geological time) where life cannot exist. The real question is what its the right amount and its MUCH higher than what we have today.



"A detailed analysis by Hay (6) of the extensive measurements taken from around the world by Ronov and Yareshevsky (10) is summarized in Figure 5. Hay’s analysis shows that today the continents contain at least 2.82 × 106 km3 of limestone, which are the remains of deposits over the past 570 million years that have not been washed to sea or subducted back into Earth’s interior. This is equivalent to a CO2 atmospheric pressure of 38 bar. If we add the carbonates found on the ocean floor, the equivalent CO2 atmospheric pressure rises to 55 bar. "

"This picture of high CO2 concentration and high pressure in the past also explains why most massive coal seams are older than 65 million years and why most limestone caves are younger than 100 million years."
