It is the established, scientific consensus that the greenhouse gasses warm our fair planet by about 33 degrees C. These gasses are primarily H2O, as a vapor, but also the relatively important trace gas CO2 and the others, N2O, CH4, etc., that are not important at all and are in fact measured in parts per Billion. That 33 number was obtained many decades ago by scientists calculating the energy in from the sun and comparing it to the average ambient temperature that exists (at the surface) and noting that something must be heating up the atmosphere because it is 33 degrees hotter than it should be. (It should be -18, not the on the average 15 we now enjoy). They reasoned that the additional energy (heat) must be from the capture of outward going heat and the only thing that could possibly do that was greenhouse gasses. (And these gasses do have the ability to "capture" infrared energy, just not very much, especially given their tiny concentrations in the atmosphere). Thus the greenhouse effect must warm the planet 33 degrees. QED.

I had never doubted that consensus. I was a believer even when I learned that Venus was very hot (at the surface) not because of the CO2 (per se) in its atmosphere but because of the very weight of the atmosphere. (Rebuttal here). The dense Venusian atmosphere compressed itself at the surface and it was hot, like the air in a diesel cylinder gets hot enough to ignite fuel, or a bicycle pump gets hot enough to burn your hand, or refrigeration compressor, etc. These things get hot not from any captured energy but merely from mechanical compression. I learned the truth of the Venusian atmosphere (still used by ignorant Warmie propagandists as "proof" that CO2 can superheat an atmosphere) but I was still in the box. I did not apply that lesson to Earth's atmosphere.

It's time to.

Here is a careful and convincing tape on what really causes the 33 degree difference. Compare it to the junior mythbusters tape. Is the one degree difference in the latter, compared to the 6 degree difference in the former, because they have soft sided containers? I sure think so.

I don't compare it to the recent Al Gore experiment as that appears to be completely fabricated through editing alone.

So here is the executive summary: The High School experiment of two jars, one with air and one with added CO2, has the CO2 filled jar get hotter because of the pressure of the CO2 not because the CO2 itself captures heat. If the jars can't get pressurized when they heat (a simple hole in the jar top) then there is no difference in the temperatures of the two jars. As we know, it gets colder the higher up you go. That's why mountains remain snow capped well into the Summer. Our atmosphere (the liveable part, the Troposphere) is only about 10 km thick and it's warmest at the bottom (the surface) and coldest at the top. The scientists measuring the heat coming in made the mistake of measuring the heat of the atmosphere at the surface. They should have measured it at center mass, which is about 5 km up, to get the average heating of the atmosphere from the Sun. There the temperature of the atmosphere is almost precisely what it should be, -18 C. The warmer temperature of the atmosphere at the surface of the earth is, as on Venus, merely the product of air pressure. There is no 33 degrees of mysterious warming. There is no measurable greenhouse effect. QED.

How does it feel to remove the blinders?

If only the Warmie true believers would learn to question authority.
