Thanks and Apologies

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.

tallbloke says:

The surface, where the measured radiation to space occurs, is at the very top of the first millimeter, or meter, or mile.

Okay…but if you adopt that definition, what you are going to find is that the surface temperature is a very sensitive quantity and you can get huge differences in average temperature for different temperature distributions that all emit the same amount of power. Hence, anything that evens out the temperature distribution (such as starting to add an atmosphere) can result in a significant change in average temperature but no change in the power radiated from the surface.
Also, N&Z justify this definition by saying that the temperature is important because that is what the energy is proportional to. However, if you have to go the top fraction of a mm in order to determine the temperature, the amount of energy stored in that fraction of a mm will be very small compared to the fraction stored in the first meter of surface, so in fact, looking at the first meter might be more representative of the energy stored.
I’m not going to spend a lot of time arguing about which definition of surface temperature is better. The point is just to understand how your result might depend on your definition…and to understand the fundamental difference between two temperature distributions (with two different average temperatures) for a surface that result in the same amount of radiated power vs two temperature distributions with different amounts of radiated power.

It doesn’t really matter much what the subsurface gets up to in terms of absorbing, retaining and conducting energy back upwards, providing you integrate the outgoing energy at the surface across all seasons and longitudes/latitudes to get your average surface temperature.

But, like I said, if you are justifying using the temperature in the top fraction of a mm as being representative of energy storage, it won’t be very useful.
If you are using it just to determine power radiated back out into space, then, yes, you should get about the same result whether you use the temperature in the first fraction of a mm or temperature in the first meter or whatever (as long as you are consistent over the surface). This is again a statement that there are lots of different temperature distributions with lots of different average temperatures that nonetheless lead to the same value for the average of T^4 and hence emitted power.

@markus ( http://wattsupwiththat.com/2012/01/17/thanks-and-apologies/#comment-869076 ): Your comments make no sense to me whatsoever. Rather than trying to respond to things I think you might be saying, I am just going to let you try to express them more coherently.

A “Frosted Banana”? I hate it when my banana is frosted…. unless it’s chocolate…
On “banning”:
Willis, it is important to remember that not all things are the public square with civil servants to keep order. Not all speech can be free to all comers (lest things degenerate into a shouting match of the Agent Provocateurs…)
So, for example, at my site, I sometimes can’t get ‘moderation’ done for a day or two at a time. There is “only one of me”. Because of that, some folks get an open microphone, others who have proven themselves little more than a PITA go to the bit bucket.
By your rules, that makes me evil and to be shunned. Sorry to hear that, guess we won’t be talking much…
But the simple fact is that my site is more like my workbook or notebook. Folks are welcome to look over my shoulder and comment, politely, or discuss among them selves. But I simply do not have the time to repeatedly enter into the same endless arguments with Trolls and related.
If I indulged them, I would spend my entire life repeating the same things: It is bad calorimetry to constantly change the thermometers. You can NOT average temperatures from ‘different things’ and the air at a place is a different thing in a few hours with different humidity et. al. You can not average intrinsic properties (and temperature is an intrinsic property). Models can NOT conduct experiments. Model output is not “data”. etc. etc.
So folks get told: Be polite, add something to the discussion, don’t consume too much of my time, and try to push forward understanding. Oh, and soap boxes are for shipping soap and trolls get tossed under the train trestle…
Most folks can handle that. Some can’t. Again, by your rules, you would be one of them.
So I’d suggest a bit of a ‘rethink’ about standing on principles of demanding an open forum at every forum, especially in the light of the reality of a lone person trying to manage their time so that they can get some work done; while trying to prevent the graffiti artists from turning the place into a dump.
Per ‘the trick’:
Generally when ‘tricking’ folks, you just end up looking either mean, or dumb. Folks don’t like to be tricked, and they don’t like seeing others ‘tricked’ either. Me? Don’t really have an opinion on your ‘trick’. I didn’t stay around that thread long enough to ‘figure it out’. To me it just looked like you were being a bit high strung. Even with this posting, that old evaluation stays. ( It is hard to go back and rewrite old memories, so I’m not bothering… yes, sloth.)
It may well have been all the things you described it to be. I’m not going to put in the effort to verify (and will not just accept as presented). I’d only suggest that if you need to apologize for something, it usually was not all that neat a trick…

“Please oh please would you do a test to show how much blue visible light heats water?”
I don’t need to do a test sweety. It doesn’t heat water to any extent that I could afford to measure. Water is transparent to visible light. The light falling on the ocean heats the solid impurities in the water. Depending on water clarity it can be a hundred meters before most of the light is absorbed.
Now you know.
Perhaps you’d care to watch an experiment where blue light is heating solids.

Joel Shore said:
However, if you go several centimeters down, you find the temperature remains remarkably uniform between day and night and you get the average value of around 250 K. This is explained, for example, here: http://www.asi.org/adb/m/03/05/average-temperatures.html
Sorry…I was a little sloppy there with arithmetic. The source I linked to actually says the average value a meter down is about -35 C or 238 K. I assume what going a meter down does for you is averages over the day-night cycle but there is still considerable variation in the temperature with latitude, which is why the average temperature is still below what would be predicted as the blackbody temperature for a uniform temperature distribution.

The same site at a different page claims the average surface temp is 250K (see link below). The actual year-round constant temperature of the regolith at two mid-latitude Apollo landing sites at any depth greater than 50cm is in fact 250K. Given the moon is geologically dead and has had billions of years for conduction to equalize the internal temperature below the surface throughout the body it’s pretty safe to say 250K is correct and should at least be regarded as a good working number.
http://www.asi.org/adb/02/05/01/surface-temperature.html
“I assume what going a meter down does for you is averages over the day-night cycle”
You claim to be a physicist and that’s what you assume? I should think a physicist could do more than assume and he’d assume better than that to boot. In fact a meter down in any dry soil on the earth or the moon gives you a year-round average of the surface temperature. Diurnal variation disappears in a few centimeters.

I pinched this from Tallbloke’s site where you wrote:

tallbloke: The evidence that they have violated conservation of energy is clear from all of the amusing contortions that people are going through to try to explain to Willis and I how it could possibly not violate conservation of energy. Stephen Wilde has gone so far as to try to get around it by appealing to the gravitational redshift [2]. Unfortunately, it turns out that said effect is 9 orders of magnitude too small, besides which, we already know the solution to the conundrum that the Earth’s surface is emitting ~390 W/m^2 whereas there is only 240 W/m^2 absorbed by the Earth and atmosphere from the sun: It is that as seen from space, the Earth is only emitting 240 W/m^2…The rest of the emissions from the Earth surface are absorbed by the atmosphere. We call this the atmospheric greenhouse effect…and it is what allows the surface to emit more energy than the Earth and its atmosphere receive from the sun.

You are casting aspersions on Nikolov et al for a hypothesis that appears to violate conservation of energy and in the same breath you say the earth’s surface radiates far more energy than is delivered by its only significant source of energy?
It appears to me your hypothesis is even more hare brained than Nikolov et al. Pray tell, Shore, what generates that extra 100 W/m2 the earth radiates over and above what is received from the sun? Energy accountants need to know!

Joel Shore
January 19, 2012 9:04 am

@Joules Verne: The answer is very simple – The earth’s surface emits ~390 W/m^2 of radiation but when the satellites look at the Earth from space, they only see the Earth emitting ~240 W/m^2 of radiation. Looking at the spectrum of the emission seen by the satellites shows why this is the case: the spectrum has “bites” taken out of it corresponding to the absorption bands of the various constituents in the atmosphere that can absorb terrestrial radiation.
So, the elevator speech is this: “The Earth’s surface emits ~390 W/m^2 but some of that is absorbed by the atmosphere. (While the atmosphere itself also emits radiation, it emits it in all directions, so it absorbs more outgoing radiation than it emits out to space.) Hence, only ~240 W/m^2 is emitted by the Earth + its atmosphere, as seen from space. And, in fact, the only way it is possible for the Earth’s surface to be at a temperature such that it is emitting ~390 W/m^2 is if the atmosphere is absorbing some of these emissions, i.e., there is a greenhouse effect.”
[Okay…I’m on an elevator in a pretty tall building!]

Joules Verne
January 19, 2012 9:16 am

@Shore (con’t)
Since you seem to have great difficulty with conservation of energy I want you to realize that what greenhouse gases do is, in effect, lower the albedo of the earth’s surface. There is NO WAY that the earth’s surface can emit a total energy greater than it absorbs. This would violate conservation of energy. Therefore for greenhouse gases to “warm” the surface they can do no more than allow the surface to absorb more of the sun’s energy. They do this in a roundabout way of course by not directly increasing the net absorption but rather by decreasing the net emission. The effect is the same however and so are the limits on what may be accomplished within the inviolable law of conservation of energy.

I would urge readers who are having trouble following Willis’s and Joel’s description of GHG absorption and re-radiation to spend some time looking at the MODTRAN program. There is a really nice web version at http://forecast.uchicago.edu/Projects/modtran.orig.html. You can clearly see how a GHG absorbs energy in certain bands and then re-radiates again with black body pattern for the temperature of the gases doing the radiating.

@Joules Verne: I am really not sure what you are even trying to argue at this point. Why don’t you come up with some sort of clear statement of your beliefs?
I have explained to you very simply how it is possible for the Earth’s surface to emit more than 240 W/m^2. If you believe there is any other way that this can be done without invoking a greenhouse effect, then you need to explain it and we’ll explain why you are mistaken.

What’s an elevator speech?

Joel Shore
January 19, 2012 10:48 am

@Joules Verne: One basic point that you seem to be missing is that Willis and I are not concerned about the surface energy balance, which is complicated because there are other ways that the surface can receive and emit energy. What we are concerned about is the global energy balance of the Earth + atmosphere system (what is usually called the top-of-the-atmosphere energy balance).
The point is that at the top of the atmosphere, the Earth system can only be emitting back out into space the same amount of power that is receiving from the sun (or else it will warm or cool). And, the problem is that if the surface is emitting ~390 W/m^2 and the atmosphere is not able to absorb any of this and prevent it from escaping to space, then the Earth system will be emitting 150 W/m^2 more than it receives. Notice that no amount of moving energy around within the system is going to save you from this fundamental fact because the only significant way that the Earth system communicates energy with the rest of the universe is via radiation.

While I wait for a description of visible light heating land, as I’ve requested re this:

“Please oh please would you do a test to show how much blue visible light heats water?”
I don’t need to do a test sweety. It doesn’t heat water to any extent that I could afford to measure. Water is transparent to visible light. The light falling on the ocean heats the solid impurities in the water. Depending on water clarity it can be a hundred meters before most of the light is absorbed.
Now you know.
========
I know well that water is transparent to visible light…..
That water is a transparent medium for visible light and can’t heat it – but that’s not the AGW sales pitch about it, and I’ve had enough arguments on the subject and been enough references and so on to know that’s exactly what is taught – that visible light reaches the surface of the Earth and heats the water in the oceans. This is energy budget you’re all working to, that short wave radiation from the Sun heats the land and oceans, the KT97 model, the whole of the global warming energy budget is based on this, that thermal infrared direct from the Sun does not heat land and oceans.
You’re the first to agree that water is transparent to visible light and visible light doesn’t heat it…
..everyone else argues that water absorbs visible light, and that blue light because it goes deeper heats the water even further down. The teaching is ubiquitous, for examples:

“On average, about 51% of the sun’s radiation reaches the surface. This energy is then used in a number of processes, including the heating of the ground surface; the melting of ice and snow and the evaporation of water; and plant photosynthesis.”
http://www.eoearth.org/article/Greenhouse_effect?topic=54099

Light transmission and absorption
“Light absorption in the open ocean [5]Life depends directly or indirectly on energy from sunlight. In the ocean, marine plants and protoctists use green chlorophyll and a few accessory pigments to capture the visible light from the sun. A large fraction of that sunlight is reflected from the sea surface back to the atmosphere. The remaining light enters the water and is absorbed by water molecules. Approximately 65% of the visible light in water is absorbed within 1 meter of the sea surface. This energy is converted into heat and elevates the surface water temperature.”
http://www.euromarineconsortium.eu/wiki/Open_oceans </blockquote
This is a given in this energy budget, that visible light heats the water of the oceans is the common teaching, so your version is different – give me the facts and figures of how much visible light heats "the solid impurities" in the oceans – I haven't seen details on this, no descriptions, explanations or any figures. This should be interesting.
And careful with the sweety, or you'll have Latitude to deal with…

Thanks, hmccard. My “Gavinesque-tone and demeanor”, I like that turn of phrase, although next to the Sultan of Scissors I am but a poor peon.
I said I would snip things that were off-topic. You try doing it in other than a fairly fast style, with very short comments, and you’ll be there for a week. I was trying to keep the damn thread on line, and nobody but nobody wanted to give an elevator speech. So yeah, you’re likely right, I got cranky about everybody first posting stuff that was way, way off-topic and then bitching me out for being snipped.
So you are right, hmccard, and let me offer my apologies, since this thread is thanks and apologies, to anyone offended by my tone and demeanor. I really did want to keep the thread on line, and I got crabby when it went all to hell, and I apologize for that.

Willis,
Thanks. My earlier comments were intended to convey to you that, IMO, in your role as a self-moderator, your tone and demeanor was a turn-off. You have now received that same input from a large number of commentors and appear to learned something from your experiment.
BTW, having been a lurker on this blog for several years; this may be my 5th or 6th comment. You are correct and I will not return to this or your previous thread; a week was enough for me.

Joules – while I’ve got the page up here’s another example, this time of a page which, as you did, gives a bit of truth and then screws it.
http://www.scienceandthesea.org/index.php?option=com_content&task=view&id=373&Itemid=10

Graph showing the wavelengths of infared, visible, and ultraviolet light. Credit: National Oceanic and Atmospheric Administration
“The infrared energy is invisible to the eye, but we feel it as heat. Most of the Sun’s infrared energy is absorbed by water vapor in the atmosphere. The fraction that hits the surface is absorbed in the top few feet of the water, heating the ocean surface.
Most of the energy that penetrates the atmosphere is visible light — what we see with our eyes. This, too, is converted to heat as it enters the water.
But some of this energy is absorbed by microscopic plants that float near the surface, or by larger plants rooted in shallow waters. They combine the sunlight with carbon dioxide, water, and nutrients in a process known as photosynthesis. This process creates the food that sustains the plants. It also produces oxygen, which is released into the water — and some of which eventually escapes into the atmosphere.”

So, factual physics they say that the heat we feel is the invisible infrared, bully for them, that’s a first from my considerable reading of such pages. It then degrades it to appear insignificant by repeating the sf meme that only a fraction reaches the surface and absorbed in the first few feet of water, but which is better than the usual centimetres or not even getting through the surface tension… 🙂
Then back to plot to push the impossible, the ‘most of energy meme is visible light’ that penetrates atmosphere and yes, “this, too, is converted to heat as it enters the water”
It then says some of this energy absorbed by plants for photosynthesis…
Do you see the disjunct here?
If visible light is converted to heat as it enters the water then it is no longer visible light, so there’s no visible light for the plants for photosynthesis.
Oh, some of it is for photosynthesis. OK, How much is converted to heat and how much left for photosynthesis, and most importantly, how does it achieve this?
This is the problem I have with the AGWScience Fiction memes, because they’re not based on real physics, they cobble together anything that someone reading without logic metre on or newbie or without real physics understanding of this, isn’t likely to spot it’s gobbledegook. Because, it is now taught universally as if it is real physics, people don’t generally question it. They’re expecting to read something like it or they’re new and think this is being educated.
This isn’t just some web site set up by a fan of AGW, this comes from the University of Texas.
“Science and the SeaTM is a production of The University of Texas Marine Science Institute on the Gulf of Mexico in Port Aransas, Texas.”
I don’t believe the meme that only a fraction of thermal infrared, the thermal energy of the Sun coming direct to us, reaches the surface, because, I haven’t any real world data on it or figures I can trust, and, because it’s the larger portion of the radiation reaching our atmosphere, and, it doesn’t get bounced around the sky like visible.., but mainly because it is the real direct heating mechanism of the oceans by the Sun. Water is the great absorber of thermal energy, heat.
Visible really doesn’t heat oceans and land, does it?
=====================
Willis
And I’ll say again Willis, your elevator speech is based on manipulated figures incoming, so the most obvious reason the outgoing is more is because there’s some incoming energy unaccounted for. If they accounted for it, they wouldn’t be able to pretend that it was all ‘back radiation from greenhouse gases’…

I am not understanding the firestorm of criticism directed at Willis. I’ve read through a great number of the replies and the reasoning for the harsh criticism, but it all falls flat.
Willis never deceived anyone. He stated exactly what he was going to do, and then proceeded to do it. To – the – letter.
The only thing he kept hidden was his motive. Hiding his motive is not deception, since he stated in advance what he was going to do.
There are accusations directed against him that just plainly don’t make sense. For example, James Sexton accuses Willis of attempting to deny Roger his liberty. How does that follow? What liberty is Willis denying? Willis exercised his only liberty by discussing the issue, and then using a tactic to drive his point home and keep the discussion alive Roger exercised his liberty by keeping his blog policy intact. So where’s this liberty denial? If free speech in the form of criticism is interpreted as denying some else’s liberty, then that is a seriously warped view of liberty.
As to Willis’ primary point: On this blog and elsewhere, Realclimate, Skeptical Science, and others are routinely criticized for using their moderating powers to silence any dissenting opinions. IMO, this criticism is valid. Most of the high-profile skeptical sites allow dissenting opinions. Many will bar disruptive behavior, but genuine difference of opinion, particularly over scientific matters, is allowed and even encouraged. For Roger to ban someone for interpreting the scientific data different then how Roger interprets it is ceding the moral high ground. Roger runs a high profile skeptical site. Therefore, his behavior at that site reflects on all skeptics. I think he is wrong for doing what he is doing.
Roger is free to keep his policy as it is. Willis is free to continue to criticize him because of it. Willis is even free to use tactics that that he does not share his motive as to why he is using that tactic, to keep up his criticism. Liberty.
As Willis points out, we do not participate on these blogs so we can all hold hands and sing kumbaya. We are here to express our opinions, and hopefully learn something from one another. That will sometimes lead to disagreements. That’s ok – as long as we are free to discuss those disagreements.

I believe the results of all this blather is zippo….just blather. It might have even increased the the heat of the earth by expending energy on all the PCs and networking gear that had to function while the notes were generated and sent. So in the interest of global warming reduction, could we end this rabble now that the net remains zippo accomplished. Thks Bill

LoL@’The Fiskars of Doom.’
Oh, I love good drama. Not cheap drama, the kind I have to make over at Topix where I repeatedly drive spikes through heads of people with whom I disagree: but good drama, where you can tell the wife and kids.
Although Willis I must say, the long line of disapproving posts is as hilarious as any of it, because EVERYBODY WANTS FREEDOM BUT NOBODY WANTS TO PUT ON THE BRASS KNUCKLES AND GO OUT FINDING AND KILLING THINGS IN THE DARK COLD MUD to KEEP it.
Freedom isn’t free girls, it requires a lot of overlooking the inCREDIBLE tackiness of not simply drowning the babies with the wrong moon sign,
AND, it REQUIRES Y.O.U. to be as T.O.U.G.H. as N.A.I.L.S.
All weather,
All conditions,
All comers.
And let the most intelligent ones feed the other ones
to Darwin’s Dogs.
Thanks for sponsoring the entertainment Tony; the very fact I endorse this means it’s probably a bad idea to the current generation of politically correct consensus monkeys who replaced the PIONEERS of freedom
When freedom meant you could actually pay for whatever you did, with whatever you had, and there not be any court of appeal from evolution.
Modern Americans are learning again what Europeans learned a long time ago.
Tribalism lends a sense of security, but it still doesn’t mean the entire camp can’t be overrun and entire legacies lost to having the wrong idea:
O.N.C.E.
So toughen up skeptics, and keep baiting those future Darwin’s Dogs’ t*rds. You WILL win: you will NOT win by being too polite to prove who’s a stupid lunge monkey.
Only non stupid lunge monkeys will make it out of the tree, across the grass, with a handful of seed heads and grasshoppers,
and back up the next tree, before the lions even know it’s time for breakfast.

Thank you Khwarizmi, now I ‘see’ the problem…
We’re talking about the effect of light direct from the Sun in the AGW KT97 and ilk energy budgets, we can make a carbon dioxide laser and burn through steel, does carbon dioxide do that in our real world atmosphere?
If we are to draw conclusions about our real world physics from using artificially enhanced technology of laser visible light properties then the Sun would have burned us to a crisp yonks ago…
Visible light direct from the Sun is benign to matter, you don’t get your eyes destroyed by looking at a patch of blue sky. (In case there’s anyone reading this who doesn’t know, the reason you’re seeing blue is because the blue light is being reflected back into your eyes.)
This is yet another example of what pees me off in these arguments, that properties of one thing are given to another, that processes and laws taken out of context, the actual context to which they apply, and then being given as examples to prove something in another context and with different properties altogether. And now added to that being given explanations which state a truth that has been a bone of contention in the climate wars, followed by more junk science to confuse even further.
So I’m not overly impressed by Joules’s post to me, as I showed another example in the University of Texas piece.
Then you say:

Well no, not Q.E.D. How does light attenuation in the ocean prove that “the light falling on the ocean heats the solid impurities in the water”?
What do you think that is showing anyway? Joules understands this point about water being a transparent medium for visible light – he’s not disputing that, what he’s not come back with is any proof that light heats solids, anywhere, the land or in the sea.
It’s now becoming just a bit harder for the “visible light heats the oceans” meme to be sold by AGWSF, even if only here on WUWT.., but I gave examples of how this is still the basic teaching about it from the AGW crowd.
It’s physical nonsense because it is well known that water is transparent to visible; visible isn’t, on a physical level capable of heating water – it doesn’t even get to play with a water molecules’ electrons as does visible light in the sky play with electrons – where the electrons of oxygen and nitrogen actually absorb it and then reflect/scatter it, that’s the blue sky you see as the effect.
This absorption is real in the technical meaning of the word in this context, actual absorption of visible light’s energy by the electrons, – so how much is it heating the sky?
