Climate Change, page-962

You need to go take some classes in physics, geology, and chemistry.

I'll repeat. If CO2 was a climate driver then, as water releases CO2 as it heats up, we would be in an inescapable feedback loop. More heat = more CO2 = even more heat = even more CO2. We would have had a runaway global warming billions of years ago (or ice age if the initial perturbation was cooling).

There are TWO long term drivers of the climate on earth. The Sun, and CO2.

These act together. (man, this is basic physics stuff we're getting in to.)

Here is a re cap - The earths temperature over 500 million years.
Solar output has got 4% stronger in that time.(Here's the source - no appeal to authority that you often confuse) https://www.researchgate.net/publication/262452752_Can_a_variable_gravitational_constant_resolve_the_Faint_Young_Sun_Paradox)


Amazing, no correlation!

So, QED the sun has no effect on the Earths temperature.

Well, not quite. You might to that conclusion because you have no scientific literacy. Fortunately most people can do a bit more critical thinking - those fifth graders I mentioned the other day.



And here's when you put the two together. Amazing correlation.

So, now, back to your point. "we would be in an inescapable feedback loop. More heat = more CO2 = even more heat = even more CO2. We would have had a runaway global warming billions of years ago"

So, what stopped earth from continually heating up? Lets check the scientific journals. https://pubs.geoscienceworld.org/gsa/geology/article-abstract/25/5/447/206678/An-atmospheric-pCO2-threshold-for-glaciation-in

A weaker sun, the position of the continents, and a decline in CO2 levels. How did the CO2 decline? The reason carbon dioxide levels fell during the Ordovician, the Atlantic Oceanic crust was subducting under the North American continent this thrust up the Appalachian Mountains as they rose the silicate rocks in these newly formed mountains rapidly weathered this happens through a simple chemical process. Carbon dioxide reacts with silicate rock, forming calcium or magnesium carbonate this is washed away into the sea, gets taken up by organisms in their shell sand then gets buried as sediment that turns into limestone or chalk so the carbon that was once in the atmosphere got buried at sea and over millions of years trillions of tons of carbon were removed from the air.

So thats why we didnt see runaway global warming in the past.
