Hi Larry.

I do not know if you have followed the arguments between me and others here over the years.
There seems to be some differences of opinion about the details to the cause of atmospheric pressure and temperature changes, specifically in the long term, such as global warming.

I accept the fact that the Sun is the major source of energy that causes the global climate and weather here on Earth
I also accept the thesis that the greenhouse gases can change the weather patterns and perhaps the climate.
On top of these beliefs I suspect that the use of nuclear power by many counties has been in a manner that is irresponsible and the resulting exhaust (radioactive pollution) from the use of nuclear power may be causing changes in the atmospheric conditions.
My suspicion is based partly on principles of physics and partly on observation over a period of time.

The physics part comes mainly from the Bernoulli's equation which states that, p + qv2/2 + qgy = constant.
where p is the pressure, q is the density, v the velocity and y the height in a gravitational field of strength g, all measured at the same point.

The observation side goes back many years and includes information from the news media and the Internet.

Such as this one.

The number of 100-acre lakes fell from 10,882 to 9,712, a decline of 1,170 or 11 percent. The scientists said 125 disappeared, replaced by vegetation.

Lowering of the atmospheric pressure would cause greater evaporation rate.

From the following site:

http://www.oma.be/BIRA-IASB/Public/Research/Meso/AppliedStudy.en.html#global_change

Concerning the global (worldwide) climate change, long-term measurements show that the mesosphere has cooled during the last fifty years.

When I read this it occurred to me that cooling by evaporation is a similar effect.

The considerable sensitivity of the mesosphere to external perturbations makes it an outstanding place to test our knowledge of physics and chemistry in the atmosphere and to warn us for future changes in the lower parts of the atmosphere. So either we can explain the evolution of the climate in the mesosphere, and we will have more confidence in the validity of our predictions concerning the influence of human activity on the global climate, or (more likely) we will not be able to fully explain the evolution and we will be obliged to do further research before we can rely on calculated predictions.

From this site:

http://www.ace.mmu.ac.uk/eae/Atmosphere/Older/Thermosphere.html

The thermosphere (literally "heat sphere") is the outer layer of the atmosphere, separated from the mesosphere by the mesopause. Within the thermosphere temperatures rise continually to well beyond 1000°C. The few molecules that are present in the thermosphere receive extraordinary amounts of energy from the Sun, causing the layer to warm to such high temperatures. Air temperature, however, is a measure of the kinetic energy of air molecules, not of the total energy stored by the air. Therefore, since the air is so thin within the thermosphere, such temperature values are not comparable to those of the troposphere or stratosphere.

What would happen if we added more energy there than what the Sun gives?

"The Earth's atmosphere is full of energy. This energy drives the world's weather, and shapes the climates. Over the longer term, changes to this energy can bring about variations in climate. "

"When the Earth receives (light and ultraviolet) energy from the Sun, much of it is absorbed either by the atmosphere or at the Earth's surface. The Earth re-radiates (infrared) energy back to space, such that there is a balance between incoming energy from the Sun and outgoing energy from the Earth. This global energy balance maintains a fairly even temperature at the surface of the Earth.

Radioactivity also IS energy, weather that energy is from natural and slow decay or induced fission reaction of the atoms.

The Earth has an 'escape velocity' is here
There are radioactive elements in the atmosphere information is here
Radioactive elements create 'heat' information can be found on the 'net' under 'nuclear power'.
Some atmospheric molecules are escaping into space, information is here

Some people here do not believe any of this and that is why the negative remark from Tom.
