Don't Tell the "Experts"

I have posted the following comment on my Venus: No Greenhouse Effect page, in response to someone wanting to argue theory, rather than accept the simple facts:

I received your second comment, but I will not reward you for ignoring the plain facts by allowing you to whine about how reasonable you are in questioning the Venus/Earth comparison presented on this page.

However, since I know that even the "climate science experts" are incompetent, I will make the Venus/Earth comparison very simple for you. But you can't tell any "experts", because I want to leave the analysis just as I originally did it here, back in November 2010, because any real expert would have, like me, focused upon the actual bottom-line of the comparison--the fact of the presented Venus/Earth temperature ratio, and the physical explanation of that ratio I have given, over and over for 2 and 1/2 years--rather than gotten sidetracked by how I came to do the comparison. And I want that to become clear to everyone, eventually--that any competent physicist should have seen that the actual Venus/Earth temperature ratio, over the range of Earth tropospheric pressures, is explained (and precisely so, above and below the Venus cloud layer) by the ratio of the two planets' solar distances, and nothing else. That is the fact--I repeat, the FACT--you are ignoring.

Here is the simple way to look at the comparison. Make a table of temperature vs. pressure for the Standard Atmosphere troposphere, and the same for the Venus atmosphere as measured on October 5, 1991(over the same range, of Earth tropospheric pressures). You don't have to justify doing that, it is just something you can easily do (it is the first table in my article above), and it is what any competent student--much less experienced scientist--interested in comparing the two atmospheres would do as a matter of routine.

But, having done that little chore, a good physicist would ask if there is a simple explanation for the fact that the Venus/Earth temperature ratio is in fact basically a constant (1.176), and that particular constant. A merely competent student in the physical sciences would pretty quickly discover that the temperature ratio is just that expected from the different solar distances alone, from the Stefan-Boltzmann formula. (How using that formula can be justified is what most critics of my analysis homed in on, but they did so incompetently. And it was not until a year and a half later that I myself added an update that properly explained it, with the physically pertinent simple equations.)

Now here is where the really simple part comes in, that was not in my original presentation, but should have been brought out very quickly by any real "expert". Imagine if Venus were simply moved outwards to the same distance from the Sun as Earth (so it was still heated by the same portion of the incident solar radiation, but that portion would be reduced, as the total incident solar radiation would be, by the greater solar distance), how would the Venus temperatures, at the various pressures in your table, change? The answer is that they would be reduced, by the factor 1/1.176--and that is what is shown in the fourth column of my table above. Graphing the resulting T vs. P curves of Earth and the newly-moved Venus, one gets the graph I presented in the post here.

Now, don't tell anyone what I have just told you, about simply "moving" Venus to the same solar distance as Earth. I want to see how long it will take a competent scientist to come to the realization on their own, instead of incompetently saying, 1.176 is "just a coincidence", or "you failed to account for the difference in albedo". Of course, you are free to inform President Obama of how easy it is to disprove the CO2 "greenhouse effect", which he and the EPA are using for the most venal of political purposes (to wit, the exercise of ruinous and fraudulent power over the lives of millions of innocent and unwary people).
