Reality check

Here's a conversion into pounds per square in per foot of water.  Keep in mind that atmospheric pressure is about 14.5 lbs per square inch at sea level.  What I'm doing here is to show that the proposition that changing the Earth's atmosphere by tiny amounts isn't going to have anything to do with the climate.

If you run the calcs, it will show that at 1 atmosphere, you will need to submerge to about 32 feet.

Consider that the ocean's average depth is 14000 feet and the oceans cover over 3/4 ths of the Earth surface, then you can calculate the average pressure per square inch of the Earths surface over that amount of surface.  This means that the average pressure on the Earth's surface in its oceans is about 418.5 atmospheres.  The rest of the Earth's surface is dry and the air pressure is by definition LESS than 1 atmosphere.  Update:  The average elevation of the dry land surface of the Earth is about 2000 feet.

When you add Carbon dioxide to the atmosphere, you exchange 1 oxygen molecule for 1 carbon dioxide molecule.  Even if you replace ALL of the Earth's oxygen with carbon, you only increase the mass by about 1/3.  This pales in comparison with the Earth's oceans as we see in the above paragraphs.

It's the Earth's oceans that trap all the energy.  The atmosphere doesn't do that very well.  Frankly, from the above, it should be easy to see that NO MATTER WHAT YOU DO TO THE ATMOSPHERE, you cannot change pressure very much.

What is the significance of this.  It is pressure that traps the heat.  Pressure is nothing more than matter piled up on itself.  The atmosphere doesn't have much of that.  The oceans DO.

Global warming is a scam.
