Some time in the past I wrote the following.

"How 'HIGH" are you R.L.?
How does the cannabis grow at that altitude?

Actually the barometer MIGHT be used to give an indication of the POSSIBLE decrease in the Earth's atmospheric density.
I would suggest taking the average pressure for each year for a period of hundred years and checking to see if there is even the slightest increase or decrease in the quantity over that period. An increase might indicate an accumulation of dense gasses such as carbon dioxide or carbon monoxide, and decrease MIGHT indicate a loss of atmosphere.
I truly would like to be PROVEN wrong and those measurements might do it."

Why don't you simply give me the actual barometric figures collected over a long period of time from a specific spot anywhere on this planet, high altitude would be better than low. Those figures may contain the information that is needed to confirm or deny this hypothesis.

The numbers that you pulled out of your a** have very little to do with the phenomenon that I am trying to explain.
Have you ever conducted or even witnessed the experiment where water is made to boil and freeze at the same time?
Do you understand what happens in that experiment and do you know why it happens?
Do you understand why water in an open container does not get any hotter than the boiling point?

Do you understand how storms develop?
Do you understand how and why a breeder reactor works?
If you understand the mechanics of how the kinetic energy is generated in, and transferred from, a radioactive or decaying nucleus to its surroundings, then please tell us.
Why does a neutron split up into a proton and an electron when it is taken away from the nucleus of an atom and how is the energy from the reaction absorbed by the surrounding particles?

I agree that the energy from the sun is the major contributor to the temperature of the Earth's atmosphere, but my original question still stands.

Are we increasing the kinetic energy of the atmospheric molecules, by allowing radioactivity to increase in the atmosphere, to such a state that some of the atmospheric molecules can escape into space?

Hot weather seems to bring out the worst in people, me included.
The air conditioner is broken and it is over 30 C degrees in here.
