Guest Post by Willis Eschenbach
I have no use for people who censor and ban those who don’t agree with their scientific ideas. I’ve had my simple, on-topic, scientific comments censored over at RealClimate. And I’m banned at Tamino’s “Closed Mind” blog for asking one too many unwanted questions. I really, really didn’t like either experience at all.
Given that, what was up with my snipping opposing views on my thread called “A Matter of Some Gravity“? I did two things in that thread. I offered up a proof that no possible mechanism involving a transparent, GHG-free atmosphere could raise the temperature of a planet above its theoretical Stefan-Boltzmann temperature. I also put out a call for “elevator speeches” explaining the “gravito-thermal” theories of Nikolov and Zeller (N&Z) and Hans Jelbring. An “elevator speech” is a very condensed, very boiled-down description of how something works. It is how you would explain something if you only had the length of an elevator ride to do so.

Well, actually I did three things in that thread, not two. I snipped out a whole bunch of comments. Oh, it was no surprise, although people acted like it was, because I had announced in the head post that I would do exactly that. But why would I snip comments, when I’m so opposed to censorship?
Therein lies a tale …
This all got started when Roger “Tallbloke” Tattersall, the proprietor of a skeptical climate blog called “Tallbloke’s Talkshop”, banned Joel Shore from posting at the Talkshop. Why? I’ll let Roger the Tallbloke tell it:
… you’re not posting here unless and until you apologise to Nikolov and Zeller for spreading misinformation about conservation of energy in their theory all over the blogosphere and failing to correct it.
OK, Joel Shore was banned for spreading misinformation that N&Z violated conservation of energy. Now, this was a double blow to me. First, it was a blow because the Talkshop is a skeptical site, and for a skeptical site to ban someone for “heretical” scientific beliefs, that doesn’t help things at all.
Second, I had also been going around the blogosphere and saying that the N&Z hypothesis violated conservation of energy. I had done exactly what Joel had done.
Don’t get me wrong here. Joel is not a friend of mine, nor an enemy of any kind. He and I disagree on many things, because he’s an AGW supporter and I’m a climate heretic. In addition, he doesn’t suffer fools gladly, and he can be obstinate about what he considers to be basic science. So I understand that he’s not the best houseguest, although I’m hardly one to talk. But we agree on this particular scientific question.
So, I posted a comment on the “Suggestions” thread over at the Talkshop asking Roger to rescind his fatwa on Joel. I pointed out that I had done the same thing as Joel, and thus in good conscience I would have to leave as well. I said that Joel is a physicist and as such is one of the few anthropogenic global warming (AGW) supporting scientists willing to engage on the skeptical blogs to defend the AGW position. From memory (I can’t go back to check) I said I enjoy it when Joel comments on my posts, because his science-fu is generally good. Yes, I disagree with him a lot, and yes, he can be a jerk (quite unlike myself), but he shows up on skeptical sites and will take the time to defend his science. Not many AGW scientists you can say that about.
Regardless of my importunings, Roger remained unmoved. So (at his very reasonable suggestion) he and I took it offline to an email discussion. I continued to plead my case and to ask him to recant the Orwellian Heresy. I enjoy visiting the Talkshop, Roger is a good guy, I didn’t want to have to leave.
In our discussion, I said that I doubted greatly if he could even give me a clear, concise, meaty scientific summary of N&Z’s theory, an “elevator speech” on the subject sufficient to see if it did violate conservation of energy. He refused to have anything to do with the idea, I believe partly because in his lexicon an “elevator speech” was a sales tool. I assured him that no, no sale necessary, I meant something different. All I wanted was for him to boil down his own thoughts and understandings to a clear precise few sentences explaining the theory, so we could see if N&Z did violate conservation of energy.
He refused. I could see he was unshakeable.
Hmmm … I was left with a bit of a koan. I wanted to see if I could fomally show that N&Z violated conservation of energy. I wanted to see if there was anyone out there who actually understood either the Jelbring or N&Z hypotheses and could explain them to me. And finally, I wanted to keep the issue of censorship alive, not just on WUWT, but at the Talkshop as well … and how could do I do that when I can’t comment at the Talkshop? I wanted it kept alive because banning someone when they say your pet idea violates scientific laws is a Very Bad Idea™—bad for the skeptics, bad for science, bad for progress, bad for everyone.
So I fear I set a trap for Tallbloke. Yeah, I know, I probably shouldn’t have done that, and I’ve likely blown my chance for eternal salvation, although there are those who would deny I ever had one, but I gotta confess, that’s what I did, and there you have it.
First, I thought up and I wrote up and posted a formal proof that the N&Z theory violates conservation of energy. I think it’s actually quite a clever proof.
Then I made a call for either elevator speeches, or for falsifications of my proof. I said didn’t want anything else but those two things, and I said that I would snip off-topic responses, because I wanted to keep the thread on track and on topic. I wanted to see if anyone could falsify my proof, and I wanted elevator speeches, and I wasn’t interested in diversions or declarations or anything but those two things.
So that was the background and the scenery for the trap. What did I put out as bait in my hunting of the snark?
Right at the end of the post, as kind of a throwaway bit, I mentioned that since I’d said N&Z violated conservation of energy, and Joel Shore was banned for doing the same thing, I considered myself banned at Tallbloke’s as well. And I do consider myself banned until he rescinds it. I knew he would react to that.
What else? Oh, yeah, the final touch, I was particularly proud of this one. I posted a link to the N&Z paper and a subsequent discussion paper on WUWT. And then I talked about the Jelbring paper, but I didn’t link to it. I knew that Tallbloke had a copy of it posted up at the Talkshop, and I was hoping he would provide the link.
Then I sat back and waited and tended my fishing lines. True to form, people wanted to make all kinds of random comments. I snipped them. People wanted to post their own pet theories. I snipped them, I’d specified no pet theories. People wanted to school me on some meaningless point. I snipped them. People wanted to complain about being snipped. I snipped their complaints. Off-topic, sorry. People wanted to re-post some off-topic thing I’d snipped. I snipped it again.
Very few of the responses were what I had asked for. Shocking, I know, but getting WUWT folks to follow a request is like herding cats. Make that herding feral cats. On third thought, make that herding feral cats on PCP.
And I’d counted on that. I merrily snipped anything that was not an elevator speech or a falsification of my proof, and watched my fishing lines.
Predictably, when Roger showed up at the party, he was not a happy man. He posted a comment containing a whole mix of stuff, little of which had anything to do with either an elevator speech or a falsification of my proof, although there was a bit of science in the mix.
I happily snipped it, science and all. I believe he has it posted over at the Talkshop to prove my perfidy. In any case, at this point it’s been restored on the thread for all to read.
Of course, Roger reasonably and strongly protested the censorship. I said repost the science if you think I snipped serious stuff. He reposted the science, minus the various off-topic things he’d included before, and we discussed it.
Then, as I was hoping against hope, he noticed that there was no link to the poor Jelbring paper. I’d left Hans out in the cold. So as I had hoped, Tallbloke posted a link to where the Jelbring paper is posted at the Talkshop.
I snipped that as well, explaining that there was no way he was going to use my thread to send traffic to the Talkshop …
Well, that seriously frosted his banana. He hadn’t even thought of driving traffic to his site, he just wanted to give people a link to the paper. To be falsely accused like that put his knickers in a right twist.
So I snipped for a bit longer to keep up the charade, didn’t want to stop immediately and give away the game, then I went to bed … in the morning I stopped snipping, and let the thread go on its merry way, diversions and pet theories and all the rest.
The response was beyond my wildest hopes. Tallbloke set up a whole blog page at the Talkshop where he is faithfully chronicling my evil misdeeds of snippage. I haven’t read it ’cause I won’t go there until Joel is unbanned, but I can hardly wait to hear the description of carnage and bloodletting, starring yours truly as Willis the Merciless, ruthlessly wielding my mighty Fiskars of Doom …
In any case, I was overjoyed to hear that, it was better than I could have expected. Instead of being discussed somewhere like the “Suggestions” thread at Tallblokes Talkshop, I had a whole thread wherein people can abuse censorship in its myriad forms. Oh, they’ll be abusing me too, but as long as they are also abusing censorship I figure that is a small price to pay.
Overall? I’d rate the whole thing as pretty successful. I probably should have stopped snipping a bit earlier than I did, I underestimated the effect, so likely I overcooked the loaf a bit, but that’s better than leaving it raw. And I did manage to keep the issue alive at the Talkshop. I figured that if the Talkshop got filled with people abusing me for censorship, that the issue of censorship would be alive and well there. And not only would the issue be alive, but people at the Talkshop would be cursing censorship … whereas if the censorship issue were alive but the topic was Tallbloke’s banning of Joel Shore, people at the Talkshop would be saying that Tallbloke did the right thing to ban him. I hoped to achieve that, but I never thought I’d get my own thread. I count that as a huge win, to get people at the Talkshop to curse and discuss censorship without my going there at all.
As I’ve said before, people who think I am so overcome by my passions that I start madly snipping, or that I get so angry that I go off wildly ranting about something or someone, mistake me entirely. I am a complex and subtle man, and I’m generally playing a long game. Folks who see me as someone who unpredictably erupts in a rant underestimate me to their cost. My rants are all very carefully chosen and calculated, I have a clear, defined, and usually different purpose for each one, and my aim is to weigh and ponder each word and each tone and shading and to consider what they will do and what people will do in response. People who go ‘we’re all offended, how can you say those things, how can you snip people’ miss the point. I say and I do those things to get people interested, to rile them into telling the truth, to get them to state their own ideas, to push them to be upset and passionate about what they believe in, to give them the space and permission to be outraged themselves, and to get them to reveal to the world either the fragility or the strength of their understanding.
I don’t mind being over-the-top because my position shelters people who take other, less extreme positions. Compared to me, they look very reasonable … and folks haven’t figured out yet that those more moderate positions are quite acceptable to me and in many cases were what I was hoping for. I don’t mind being the lightning rod to make a point. I have no problem pushing and steering hard to one side, with the clear internal goal of attaining a position in the middle. I have no difficulty staking out a radical position. It allows others to take much less radical positions than I took, positions that they might not have otherwise expressed. Yes, I’m extreme, and that is deliberate.
I don’t mean that my upset or my anger are fake. They are never fake, or I could not write as I do—my passion would not be believed if it were false or contrived. I mean that I choose the time and the method of expressing that upset and anger so that I can harness it to achieve a chosen purpose or outcome.
So, I’m willing to call people out. I say hey, if you can’t explain it in an elevator speech, it you don’t understand it. I know that’s unpopular, but I take that position as a conscious choice. I’m tired of people nodding their heads about absolute scientific nonsense and saying “looks good to me”. So I insist and I nag them to take a hard look at what they are espousing.
For example, Tallbloke banned Joel Shore (and myself by extension) because Joel had the temerity to say what I say, that the N&Z theory violates conservation of energy. In response I asked TB (a number of times by now, first in private and then on my thread) to give me his elevator speech outlining the Nikolov/Zeller theory. He has not done so. I say that is evidence that he doesn’t understand the N&Z theory he is espousing. If he understood the theory and the theory was scientifically solid, he’d squash me like a bug. I’m way out on a limb here, if Tallbloke could saw the limb off he would. And I wouldn’t blame him, he’s not happy with me right now, and with reason. Since he hasn’t sawed the limb off by giving me the crushing elevator speech, he doesn’t understand the theory.
But if he doesn’t understand the N&Z theory … why is he banning Joel (and myself by extension) for saying the theory violates conservation of energy?
Like all of my actions in my posts, the pushing of people to explain their views in an elevator speech, even to the extent of snipping their posts when they didn’t do so, is a position and an action that I have taken with forethought and contemplation. And no, it doesn’t make me popular. But I’m steering to one side in order to attain the middle. I don’t expect others to call for someone to give an elevator speech, but that’s not my goal. I figure if I can reinforce the value of judging people’s understanding of a topic by whether they can explain the theory in a clear, concise manner … then who cares if I’m popular? I’m tired of vague handwaving. Boil it down to the elevator speech, then boil it again to half that size, and give us the simplest, clearest explanation possible.
In any case, the beat goes on. I’m still waiting for someone, anyone, to give us a clear, concise, scientific explanation of either the N&Z or the Jelbring hypothesis. I’m also still waiting for anyone to falsify my proof. You’re welcome to do it in this thread.
While I’m waiting, I’ve given up my persona of evil snippage, I’ve sworn off my temporary assumption of wicked ways. I’ve climbed down from the saddle and hung up my scissors with their embossed leather holster beside the gunrack near the wood stove. I’ve made my point, I won’t need them until danger threatens again. Sorry, Tallbloke, but your blow-by-blow account of how I feloniously threatened and terrified the neighborhood with my dreaded Scissors of Destiny will have to come to a premature end … they’ve served their purpose, and been put out to pasture.
To close this tangled tale, what about the thread title, thanks and apologies? Well, first my apologies to Roger “Tallbloke” Tattersall for my having played such a shabby trick on him. He is a good, honest, and decent man whose problem is that his mouth wrote a check that his science can’t cover. Roger, you have my apology, seriously meant. I just couldn’t think of another better way to keep the question alive. Please do rescind your ban on Joel.
Next, my apologies to Anthony. He and I don’t correspond a whole lot, and I didn’t warn him because I didn’t expect the amount of blowback. So I fear he got an email instalanche of people saying I’d lost my mind. Didn’t think about that, missed that one entirely, didn’t I? Mea culpa, Anthony, my bad. Folks, in the future, as I implied above, if the options are a) Willis has lost the plot totally, email Anthony immediately, or b) Willis has a plan I don’t see yet, wait a while … the answer is likely “b”. Give poor Anthony a break.
To all of the folks who screamed about being snipped, my thanks and my apologies. I did it for a couple reasons. One was to emphasize that I was serious about people giving an elevator speech. I tried to snip only what I had said I would—off-topic stuff that was neither an elevator speech nor falsification of my post. If they wanted to stand up and be counted they had to put their beliefs down clear and solid. I pushed it very hard, probably too hard for my own good, to see if anyone out there actually understood either the Jelbring or the N&Z theory. Turns out no one does, or if they do, they’re hiding their light under a bushel.
Heck, even Hans Jelbring showed up. He refused to give us a clear, concise statement of his theory, claiming that there was no way to state his theory in less than pages and pages of close-spaced text. Riiiight … if you can’t explain it clearly you don’t understand it.
The other reason I snipped was to emphasize the importance of the freedom to post that we take for granted here at WUWT. One of the issues I wanted to keep afloat was that of censorship. I wanted that fact not to be lost in the discussion, I wanted it to be one of the subjects of the thread as well … yeah, I might’ve overdone it, you’re right, but at least I dun it …
Next, my thanks. First, my thanks to people like Steven Mosher, who said he didn’t see any problems with my proof, and commented that it seemed hard for people to follow simple directions on what to post. For those like Steven who did follow my requests on what to post, to those who took a shot at falsification or elevator speeches, my thanks.
Also, for those that didn’t follow directions, you were necessary to set the scene, so thank you for playing your part.
Anthony, once again, my thanks for your magnificent blog, and for the freedom that you give me to post here without let, hindrance, or forewarning of disaster.
Finally, Roger Tallbloke, my thanks again to you. I was not my intention to harm you, but to keep alive both on this site and on your site the question of the ethics of your ban.
… and at the end, the curtain falls, the crowd departs. Ushers clean the seats, roadies pack up the trusses and the amps as the auditorium closes down, and all that is left is a proof that the N&Z theory violates conservation of energy, and a huge lack of people who understand either the Jelbring or the Nikolov and Zeller hypotheses. It’s a lovely cold, clear night here, and me and my beloved, my ex-fiancee of thirty plus years now, are going for a walk. I wish everyone the joy of living in this miraculous, marvel-filled eternity, with my thanks and my apologies.

That was not all as brief as promised and maybe even a bit “off topic” but then I would rather reserve my critical points for “catastrophical warmists” than sceptics who may or may not upset me. – By the way, nobody in this GW discussion has, so far, upset me – not yet.
Here are a few sentences that could be part of an elevator speech.
1- If the Earth was half as dense, would its surface be cooler or the same? I think the adiabatic lapse rate would be halved, but the atmosphere would go twice has high. So the temperature would be the same at its surface.
2- If the Earth lost all of its heat at a specific altitude, its gray body temperature would be defined at this altitude and the adiabatic lapse rate would define its temperature at the ground.
3- A planet cannot be cooler than if it radiated all of its heat at the ground. It cannot be warmer than if it radiated all of its heat from the top of its atmosphere.
4- If we choose a particular frequency of emission of heat. We can divide the “heat thickness” of the atmosphere in 3 cases(by “heat thickness”, I mean absorption of photons to heat):
4a- The atmosphere is nearly transparent to this frequency. Most of the emission at this frequency comes from the ground. Doubling the optical thickness would not change the average height of emission. If 99.9% of emissions come from the ground, a doubling of thickness would lead to 99.8% of emissions from the ground. This is nearly the same and the change of temperature would be small.
4b- The atmosphere absorbs about 50% of emission at this frequency. In a simple atmosphere, half of emissions come from the ground, and half come in average from the middle of the atmosphere. Doubling the thickness would mean only 25% of emissions come from the ground and 75% come from the middle of the atmosphere. This is a considerable change in the height of emissions and it would lead to a change of temperature.
4c- The atmosphere absorbs nearly all of emissions at this frequency. This “heat thickness” is certainly responsible for a warmer temperature at the surface. But, doubling the thickness would move the height of emissions from nearly the top of the atmosphere to even more to the top. In the end the average height of emissions would not change by a lot and temperature at the surface would not change either.
5- We often read that the temperature of the surface is proportional to the log of the concentration of a greenhouse gas. It cannot be totally true because the real function is floored by the ground and roofed by the top of the atmosphere.
6- The most dangerous gases to monitor would be gases that participate to an absorption of around 50% of the heat emitted by the ground.
7- Water vapor probably participates to a 50% absorption at least at some latitudes.
8- Ozone might participates to a 50% absorption but it is not well mixed vertically.
Conclusion- In simple words, the Earth and its atmosphere have to be warm enough to glow as much energy as it receives. If the atmosphere absorbs a lot of heat, emissions at a lower altitude will simply heat the higher altitude. And the higher altitude will need to get warmer to glow enough heat to space.

“This means air is denser at low altitudes, and that means more molecules are having collisions more often, thermalising energy.”
The diatribe goes off the rails with the above statement. Temperature is a mode of motion. Density is not. In fact the title of the seminal work in this area of theoretical and experimental physics is John Tyndall’s 1859 work “Heat: A Mode of Motion”. It’s free on google books in its entirety. No one here will be harmed by reading it and a great many would benefit.
I knew I didn’t want to read anymore after the “thereby hangs a tale.” bit. I should have trusted my instincts.
Bomber_the_Cat, I think this comment from anna v answers you. However, I do concede it’s possible this effect is too small magnitude to counter Willis’ argument totally.
Still, I am now taking the gravity-heat theses more and more seriously, as I find confirmation in the behaviour of other gas planets that also don’t follow S-B, as well as observations under my nose like Jericho several degrees warmer than Jerusalem.
Sadly, too much length, sharpshooting and belittling here is exhausting – like WP. I now strongly suspect Willis’ science to be mistaken, for all that it may be orthodox. But I would rather sharpen my understanding amongst more like-minded folk for a bit, and simply dip back here to ensure I grasp the key challenges that need answers. I also await the responses of Jellbring and N&Z.
However, Willis, I still love your thesis of the climate governor in the tropical thunderstorm scenario.
If . . .
it takes 3,500 words to explain a “trap”
and . . .
Einstein is correct that “If you can’t explain it simply you don’t understand it well enough.”
does it follow . . .
that Willis doesn’t truly understand his “trap” and might have trapped himself?
I have been a follower of Tall bloke for a while, and I would say I generally read more of him than Willis. But I agree with Willis that he has stepped over the line in deciding to ban someone based on their ideas. Sorry Roger but there is no real defense. All you are doing now is showing intolerence. Your making it worse.
Perhaps you missed the fact the the skeptical community is sick to death of people declaring the correct answer and trying to stop people who disagree from commenting. I think you missed the point entirely. Let them have their say, your not the gatekeeper of the “correct” any more than Mann. We can all see you over-reacted and just don’t want to admit it. But how far will you go to avoid admitting the obvious?
If you won’t prove your the better man in the fight……then your not.
We are still ‘being had’, but not as you may think. This is a long game.
WUWT is a science blog, seeking truth, come what may.
When an article of belief has been portrayed as science and then serially proven wrong, yet remains as ‘the truth’ to many, the question becomes: why do the belief and dogma persist?
Might we need to know more of ourselves in order to break through to the truth/whole truth of the matter?
Facts are not truth. Facts are mere facets of the shining diamond of truth.
Game on.
I have to say I am losing track completely now. There are posts pro-Willis and post pro-Rog; there are posts that challenge the very Greenhouse Effect itself, this despite Monckton clearing it up for you all just the other day. Who am I to believe any more on here? It seems like a random mosh-pit, a scattergun mess. I think I’ll just go and listen to Motorhead instead! That usually does the job!
Re: Lucy Skywalker 1/17 3:03 am on the need for a wiki.
There will be occasional posts on WUWT where the issue put forth requires commenters to be focused and brief. In those posts, the moderators will have to wield the scissors mercilessly. These types of posts do have value in that they can have higher value than others in the archive. They are more distilled and refined than the average thread.
When blogs find the need for such a focused topic, then to relieve the heat and pressure, blogs should create a parallel post for wider discussion that is much less moderated where comments unpruned and side-bar issues have a home.
Take Lucy’s suggestion of a wiki. The moderation workload of that endevor makes me shudder. The ability for one commenter to edit the work of another will cause a “Mater of Gravity” dust-up to go nuclear. But let’s learn from the wiki model… there is the “article”, heavily edited and moderated, and there is the “discussion” which is less moderated and allows elaboration and minority opinions.
So I suggest WUWT make it a policy that if the author of a post states that the comment thread will be closely moderated to stay on topic, then there should be a companion post to act as a safety-valve for parallel (if not off-track) discussions.
Irrespective of … what? Physical laws our your choosing?
Like certain gas-molecule interaction with LWIR (an EM wave I might add) sourced at the earf’s surface?
Ever heard of “Infrared Spectroscopy”?
No?
See links – http://wattsupwiththat.com/2012/01/17/thanks-and-apologies/#comment-867303
.
So, will I get an elevator speech (for a biologist) about where sits that N&Z error?

Actually Tyndall was well aware that what he was studying was electromagnetic radiation. They just didn’t call it short and long wave EMR back then they called it luminous and calorific waves respectively. EMR’s wave-particle duality was yet to be discovered at that time which I believe came along when Einstein explained the photoelectric effect shortly after the turn of the century.
A plea to Willis and Anthony – please can we have another new thread which summarizes the progress made so far in the first two?
I read Willis’s first article and the early comments, especially on conduction and convection, but have not read the rest, so what I write below may already have been covered. I am dismayed about the snippage which occurred, except to say there over 600 comments there when I read it. The reason for my dismay is that I fear Willis may have thrown out some babies with the bathwater, and lost some useful scientific reasoning – I have no way of telling.
So my position is that I do not know the details of the N&Z or Jelbring papers, so I cannot provide an exact “elevator speech”, but I do have some ideas on the physics which I believe are pertinent. It has to do with what is wrong about Willis’s:
—
NOTE 1: Here’s the thing about a planet with a transparent atmosphere. There is only one object that can radiate to space, the surface. As a result, it is constrained to emit the exact amount of radiation it absorbs. So there are no gravity/atmospheric phenomena that can change that.
—
When you say “transparent”, you mean that the type of atmospheric molecules let the vast majority of black body spectrum wavelengths pass through. Fair enough.
But now consider conduction (ignore convection for the moment). The atmosphere will heat up by conduction at the ground layer. And it would carry on heating up if it could not get rid of some of that heat. Even though the gas is assumed not to radiate at standard IR wavelengths, it must radiate at some other wavelengths. (Perhaps someone can tell me what they would be for nitrogen for example.) Now, when it is radiating thus, it is a greenhouse gas against its own emissions!
So some of its radiation gets trapped and bounced around, which reduces the atmoshpere’s overall radiation effectiveness, so it will heat up.
That’s my “elevator speech” against your NOTE 1.
There is the question of which level of the atmosphere will be the hottest. It should be at an intermediate level. The molecules very high up can radiate with small probability of interception by higher ones, and the molecules close to the ground can radiate to the ground which can then re-radiate transparently through the atmosphere. In the middle layers export of heat is harder.
Therefore there will be an inversion layer, and below that layer presumably there will be relatively little convection (above it is a different matter). I’m still not sure whether the ground temperature will actually differ from the lowest level air temperature.
Willis, when you’ve digested that, another “Apology and Thanks” will be dandy…
Rich.
willis has a beautiful mind. it was part of his plan. just ask parcher.
diagnostic stuff, willis.
what terrifying impotence provokes desperately deluded fantasies of being puppet master?
i’m leaving this behind with a sneer, there being no tenderness in my heart for the psychotic.
It’s not clear what was the point of this ‘game’, but surely it was not Science advancement.
Just one comment on “if you can’t explain it in an elevator speech, you don’t understand it”: even if you understand it and you are able to present it concisely, that does not render it magically true. Formal/numerical proofs usually take a lot more than 3 lines of text.
I prescribe 20 Hail Marys and 20 Our Fathers for Willis to avoid smoking a turd in purgatory over this one.
Tallbloke
If you wanted to ban Shore because he is a jerk, then say that, don’t demand something about his views on a scientific paper.
Second, people like shore and lazyteenager are better selling points for your science views than anything else. The blind devotion they show is educational to the masses, and underscores the religious nature of the AGW.
To clarify, there is nothing wrong with banning someone because they constantly attack you with personal slurs, but to demand they change their views on a scientific paper before you will allow them to post again is just fundamentally wrong. Period.
Willis
I agree with tallbloke that your appology was pretty week when wrapped in a another attack. You should do better than that. You could have wrote this story without being nearly as rude to tallbloke.
The entire ‘gravito-thermal’ thing can be rephrased as being pressure-driven as opposed to gravity-driven. Gravity does, of course, drive pressure. But it makes the entire argument seem more coherent IMNSHO.
“Stephen Wilde says:
January 17, 2012 at 8:22 am
Stephen Wilde (7:21 am) says “S – B applies to a body in a vacuum”.
Really? Where did vacuum come into this?
I’ve asked my source for clarification on that but in the mean time your link does define c as the speed of light in a vacuum and that is an integral part of the equation.”
I am somewhat sceptical about a vacuum. If a vacuum exists then it is devoid of matter, therefore devoid of energy, and therefore has to be absolute zero……
Bomber_the_Cat and Stevea_UK
Name a gas that does not radiate. Picking an example from a post above which mentioned N2 and O2, imagine a planet and atmosphere consisting entirely of Oxygen. Heat it with a sun at some arbitrary distance for long enough for it to be in thermal equibrium. Is the temperature going to infinite? Sunlight arrive at all sorts of frequencies; some will be ignored. The atmosphere will get hot and it will radiate energy. It will not increase in temperature until it reaches the temperature of the sun, will it? On the contrary, it will stabilise at some lower temperature.
If you accept the argument that Oxygen cannot give off radiation until the temperature is so high that theradiating surface of Willis’ planet will overcome the insulating effect of the atmosphere, then you have also accepted that a non-GHG atmosphere warms the surface. The empirical test of two spheres with different pressures of non-GHG gas around them shows an increase in temperature with increasing pressure. Did I understand that experiment correctly?
Stevea_UK bothered to look up some information on absorption and radiation and is now asking good questions. Bomber_the_Cat you can do the same.
Many contributors are getting the main points about this exercise: The S-B number helps you calculate the radiative component of heat transfer. If there is a vacuum, it is all the heat transfer. If there is an atmosphere of any kind, not all heat is transferred from the surface at the bottom of the atmosphere by IR radiation because all gases radiate, even it they do not absorb IR which is only a portion (an effective one) of total transfer energy.
Oxygen was given as an example of a non-GHG. Yet O2 absorbs IR at 1270 nm:

“The data clearly show that the photooxygenation of the traps is a result of their reaction with singlet oxygen [O2] that is formed due to [IR] laser excitation of oxygen molecules.”
Huh. A non-GHG absorbing sunlight. And in the IR band too. I wonder what frequencies Oxygen can radiate at…

“New emission spectra have been observed from chemically produced excited oxygen. Evidence that the observed visible emission is due to oxygen dimer transitions is presented. Experimental results suggest that the observed oxygen dimer is stable O4 molecule rather than the usually observed Van der Waals-type dimolecular complex. The present system is discussed from the viewpoint of a new laser operating in the visible. The possibility of a similar oxygen-dimer laser operating in the near-infrared is also discussed.”
Huh. An Oxygen laser that emits IR. I presume everyone has heard of Harvard.
I have not yet seen described a way to construct a no-GHG non-radiating atmosphere. Thus my question. What gas does not radiate at all at any wavelength or temperature? After we find one we can think about elevator talks.
Who made this long winded excuse monger king of unneeded confessions.
Stubborn disorders not off topic?
Deep brain stimulation, from:
WSJ: JANUARY 17, 2012. Wiring the Brain, Literally, to Treat Stubborn Disorders
“The procedure starts with a surgeon drilling two holes in the patient’s skull.”
“After two years of DBS, 92% reported significant relief from their major depression or bipolar disorder and more than half were in remission, with no manic side effects.”

Nope, I wasn’t trolling. I was fishing, for a specific purpose, which was to have the issue of censiorship remain alive. And if I wanted to “get away with it” as you speciously claim … don’t you think I would have simply kept my mouth shut? I’m here taking responsibility for my actions, even though they weren’t pretty.
OK. You’re wrong.

Willis:
Personally, the problem I found with your gravity thread, was that by the time I reached the end of the thread of comments, it was no longer clear what the starting conditions were (a common problem with me). It is easy to lose track of the thread’s purpose, and well… it is ONLY a conversation! The playing of mind games, was not helpful, nor demonstrative, in my opinion. Some loss of trust cannot be recovered completely. I abandoned the thread as I realized it was becoming non-productive.
Giving your “experiment” some sort of morality, does not justify it. Several of our best contributors now have a degree of animosity towards each other and this thread may not normalize it. The end does not justify the means, in this case. I may be wrong and we all really needed a good shaking. Who knows? GK
