Assessing the accuracy of ice-core CO2 records
In the excerpt below, David Middleton points out large problems with ice-core data and suggests that fossil Plant Stomata give a much more accurate account of past CO2 levels -- an account that gives no support for Warmism at all and which in fact supports the obvious physics of the matter: Warming causes higher CO2 levels rather than vice versa

I was hauled off to the hospital with CO2 poisoning I got whle working in the very bottom of a hydroelectric power plant underground cavern. CO2 is heavier than air (O2 & N2) and had accumulated down there.
Picture a gas filled balloon suspended in midair inside a constant velocity moving train boxcar. When the train slows down, will the ballon move forward or backward?
What the heck are you talking about? The original statement you objected to talked about the weights of gases relative to rock and water, not other gases.
Incidentally, I would expect that the mass of the rubber in the balloon and the string would tend to make the balloon move forward due to its inertia.
Here is the simple, simple rebuttal to CO2 driven warming.
1. The oceans give off CO2 as they warm and absorb CO2 as they cool.
2. The oceans are the principal well for all CO2.
3. IF CO2 was a significant driver of temperature, the Earth would drive to one extreme or the other (with the maximum amount of CO2 released or absorbed) and stay at that extreme with no way to get back. In fact, it would be impossible for the earth to stay at any equilibrium in the middle.
I would think it would work the other way around.
Othewise, we would have had a runaway move into one extreme or the other by now.
In other words:
Gore is a flat out charlatan.
Correct on the string; incorrect on the balloon .
You can test it yourself with a helium filled balloon inside a closed vehicle.
Centrally locate a balloon in a moving car, step on the brakes ... and the balloon will move backwards. What causes it to happen is the air inside the vehicle moves forward, thereby increasing air pressure in the front and lowering air pressure in the back ... and that floating balloon will float toward the lower pressure.
Interesting, but what has that got to do with the weight of gases relative to rock and water (in the article) versus the weight of gases relative to air (in your comment on it)?
Gas doesn't tend to migrate downward through sediment. Being less dense than rock and water, it migrates upward.
You and the idiot author don't seem to realize that some gases are heavier than air; and that such gases are quite capable of migrating downward through air, or downward through rocks via holes and crevices, or into liquids via absorbtion.
Hot water can't keep as much gas in solution, thus colder water equals more trapped CO2 and warmer equals more released CO2.
This is not disputed by the AGW crowd. In fact, they trumpet the fact that the warmer seas will release CO2 and create a runaway effect. What they don't explain is why this hasn't already happened in one direction or another during the Earth's long history and how it could possibly come back from one extreme.
This is truly the stake through the heart of AGW. If CO2 was a driver, the oceans would ensure that CO2 would go to one extreme and stay there.
In the meantime, you don't seem to realize that any holes and crevices in and between rocks underwater tend to be filled with water. Only a minuscule amount of air, if any, will be found in them.
Your continuing to evade the point that was being made is getting rather tiresome. I'm done.
Yes, I would agree that finding has falsified CO2-based AGW. Now they'll have to find some other culprit to justify AGW. Well, not as long as they ignore the science of it, but eventually.

So is water vapor the primary cause of Global Warming? I thought it was CO2?
I can’t find the article referenced. Has the post been taken down?
Found some local history to prove it was warmer in the past.
We use to have alligators in our river.
Here is a link about our year of catastrophic/bad weather that you might want to post separately.
