The great physicist Richard Feynman adds to three other giants of physics, Maxwell, Clausius, and Carnot, who have explained the "greenhouse effect" is solely a consequence of gravity, atmospheric mass, pressure, density, and heat capacities, and is not due to "trapped radiation" from IR-active or 'greenhouse' gas concentrations.
Only one 33C greenhouse theory can be correct, either the 33C Arrhenius radiative greenhouse theory (the basis of CAGW alarm and climate models) or the 33C Maxwell/Clausius/Carnot/Feynman gravito-thermal greenhouse effect, since if both were true, the surface temperature would be an additional 33C warmer than the present. As we have previously shown, the Arrhenius greenhouse theory confuses the cause (gravito-thermal) with the effect (radiation from greenhouse gases).
In addition, the US Standard Atmosphere, the International Standard Atmosphere, the HS 'greenhouse equation,' Chilingar, et al derive the observed atmospheric temperature profile without use of a single greenhouse gas radiative transfer equation or calculation, and using the same basic atmospheric physics discussed by Feynman in his lecture below. Feynman does not make a single mention of radiation, radiative transfer, greenhouse gases, CO2, nor does he derive any radiative transfer equations to derive the atmospheric temperature profile, and instead utilizes the barometric and statistical mechanics formulas necessary to describe the gravito-thermal greenhouse effect of Maxwell et al (who Feynman quotes extensively below). Feynman demonstrates that an atmosphere comprised solely of the non-greenhouse gases N2 & O2 (99.94% of our atmosphere, but 100% in Feynman's demonstrations) would establish the temperature gradient/"greenhouse effect" observed in the troposphere.
Feynman demonstrates that the conservative force of gravity does indeed do continuous thermodynamic Work upon the atmosphere (a common false argument by those who do not accept the gravito-thermal GHE theory is that gravity allegedly can't do Work upon the atmosphere), and describes gravitational potential energy (PE) accumulated as air parcels rise/expand/cool, which is then exchanged for kinetic energy (KE) as the air parcel descends/compresses/warms, creating the temperature gradient & greenhouse effect.

Better delete this blog and then delete reread Feijnman very carefully especially the part to the left of fig-40-1, the part that ends with the sentence:
ReplyDelete"So, ultimately, of course, the temperature becomes the same at all heights in a gravitational field."
Are you incapable of reading or understanding this paper beyond the 6th paragraph thought experiment example (the Feynman clearly states in the 6th paragraph is "in thermal equilibrium - unlike our atmosphere")? Why did you ignore Feynman stating in that same paragraph that this thought experiment is "without the winds and other kinds of disturbance," including CONVECTION, which as he later shows completely dominates radiative-convective equilibrium!
DeleteDid you not read/understand that Feynman begins to explain in the 7th paragraph and for the remainder of the entire paper why our atmosphere (and he only assumes the atmosphere is comprised of non-GHGs N2 & O2) "is not an isothermal atmosphere" due to the thermodynamic Work done by gravity upon all gases?
Clearly, you have no clue of the meaning of this paper, so no, I will not be deleting this blog nor this post upon your ignorant demands. And BTW, his name is spelled Feynman, not "Feijnman."
Very interesting article and points on Richard Feynman and his Maxwell gravito-thermal greenhouse theory. Thanks for sharing
ReplyDeletePeople seem to believe warm air rises and cools. I ask them "Where does the energy go?". They never answer. QED :-)
ReplyDeleteIn answer to Anonymous of September 20:
ReplyDeleteShort answer: It becomes gravitational potential energy.
Lon answer:
There are two types of mechanical energy: energy due to motion (kinetic energy) and energy due to position (potential energy). When I drop a brick, it stars moving quickly and has a lot of energy when it lands.
Where did the energy come from? From its potential energy due to being high up -- graviational potential energy.
When I raise air, its potential energy increases, and so its kinetic energy must decrease. Heat consists of kinetic energy of particles moving. The loss of kinetic energy causes the air to seem cooler.
I have answerd. QED :)
