Quote:
I'm not a geologist but I think core temp is more from gravitational forces than from air pressure by a very large degree.
Right, I guess I should be clearer. Atmospheric pressure is a result of the mass of air exerting gravitional weigh over the earth’s surfaces.
Believe it or not the atmosphere places huge amount of pressure onto the surface of the earth.
If the atmospheric pressure is lowered, then the body of air weighing down on the surface of the earth should also be lighter.
Adding humidity as heating usually does only even makes the atmosphere that much the lighter. Italian physicist Amadeo Avogadro discovered in the early 1800s that a fixed volume of gas, at the same temperature and pressure, would always have the same number of molecules no matter what gas is. I know water's heavier than air. Liquid water is heavier than air. But, the water that makes the air humid isn't liquid. It's water vapor, which is a gas that is lighter than nitrogen or oxygen.
Nitrogen molecules, which each have a molecular weight of 28 (2 atoms with atomic weight 14).
An oxygen atom's atomic weight is 16.
A hydrogen atom's atomic weight is 1.
In short hotter air is lighter. And therefore exerts less force upon the surface of the earth. There by relieving some of the presure on the earths core causing it to cool not get hotter.
I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago.
