Greenhouse Gas Errors Abound on WUWT Blog

By Astrophysicist, Joseph E. Postma

On this fairly recent post at “Watts Up With That”, guest contributor Willis Eschenbach developed an explanation for the Atmospheric Greenhouse Effect using steel shells, with one inside the other.  What Willis does is so intellectually offensive, so mentally incompetent, that it beggars the imagination. Willis takes an inner sphere radiating at a certain temperature as a blackbody, and then surrounds the sphere with a metal shell in order to trap the radiation.

Now, what does modern physics actually have to say about radiation trapped inside a cavity?  Let’s forget that the rules of arithmetical addition are still waiting to be defined by greenhouse effect advocates in the 21st Century, and let just pretend that the 20′th Century and the rest of mathematical history actually occurred.

The idea that a cold shell outside a warm interior causes the warmer interior to heat up some more by trapping radiation inside has always been and will always be a gross violation of basic thermodynamics; as we will see it is also an embarrassing violation of quantum mechanics and the very origin and well-known history of the idea of a blackbody.

It is also specifically the pseudoscience that has been invented to explain the arbitrary difference between the kinetic temperature of the air near the surface and the equivalent blackbody temperature of the outgoing averaged radiation – an invention based on an arbitrary and physically meaningless comparison, which isn’t necessary, because the bottom of the atmospheric layer is naturally the warmest part of the total average ensemble, and because sunlight heating in day time at the ground surface actually has an average value of +49C on the sunlit hemisphere, and this heat distributes up into the atmosphere, cooling as it goes.  It is this latter fact that the invention of a cold layer heating up an already warmer layer has been meant to replace, in order to create the foundation for CO2 alarm and hence the political and societal goals related to that fraud, and of course this was done with assistance by diluting the true power of incident sunlight to a greater surface area where said sunshine doesn’t actually even exist.  Sunlight does not exist on the surface at night time and therefore all of the pseudoscience related to this proposition and subsequent to it is false.

A cavity which traps radiation does not increase the frequency of the radiation.  It is only with an increase of the frequency spectrum of the radiation by which a radiation spectrum can induce higher temperature, and radiation can not and does not change its own frequency spectrum when trapped in a cavity. The idea that it does is a plain violation of the whole origin of Planck’s Law and the blackbody spectrum, and hence of quantum mechanics. Radiation trapped inside a cavity, such as between the atmosphere and surface, does not increase the frequency of the radiation spectrum, and hence does not cause a change in temperature – particularly when the actual source of radiation and input heating is an approximately 6500K spectrum, and the cavity radiation is only a 255K spectrum.  The internal cavity radiation of 255K is a result of the heating which initially occurred due to the 6500K spectrum input, and this cavity radiation can not increase its own temperature or its own frequency spectrum past what the 6500K spectrum input already did.  This is just basic thermodynamics.

In IPCC greenhouse physics and in the attendant fraudulent models, the idea that cavity radiation causes an increase in temperature requires that a hotter object emits less radiation and that a colder object emits more, violating Wien’s Law, Plank’s Law and the Stefan-Boltzmann Law (which are all just Planck’s Law). The IPCC models stated that a warming planet from greenhouse gases should emit less energy; the data has shown that a warming planet emits more energy. The mathematics of this invented physics also shows that at zero emission, i.e. perfect internal radiation trapping within the cavity, that at zero emission an object would have infinite temperature.  So, both an object of zero Kelvin and infinite kelvin emit zero energy.  It’s absurd.
