Two days ago I posted on this story in this blog related to APS opening up debate on climate change. It appears Lord Monckton did in fact have his paper, Climate Sensitivity Reconsidered, reviewed by APS, and he drafted revisions per that review, after which the paper was accepted by APS for publication. Yesterday, APS put this disclaimer in red over the paper on their website:
The following article has not undergone any scientific peer review. Its conclusions are in disagreement with the overwhelming opinion of the world scientific community. The Council of the American Physical Society disagrees with this article’s conclusions.
Monckton writes:
This seems discourteous. I had been invited to submit the paper; I had submitted it; an eminent Professor of Physics had then scientifically reviewed it in meticulous detail; I had revised it at all points requested, and in the manner requested; the editors had accepted and published the reviewed and revised draft (some 3000 words longer than the original) and I had expended considerable labor, without having been offered or having requested any honorarium.

PeerGate review scandal at American Physical Society
The American Physical Society alleged that Lord Monckton’s paper Climate Sensitivity Reconsidered was not peer reviewed when Monckton in fact thoroughly revised his paper in response to APS peer review. Monckton immediately demanded retraction, accountability and an apology.
The Editor of the American Physical Society’s Forum on Physics and Society launched a debate on global warming, inviting Lord Monckton to submit a paper for the opposition. After news that a major scientific organization was holding a debate on IPCC’s global warming, someone at the APS posted an indirect front page disclamation plus two very bold red disclamations in the Forum’s contents, and into the paper itself:

Alleging that a Peer of the Realm violated scientific peer review – when in fact Lord Monckton had spent substantial effort responding to the APS’s peer review – is just not done! As circulated by Dr. Benny Peiser to CCNet, and as noted by Dennis T. Avery at ICECAP,Lord Monckton responded immediately, emphatically demanding redress and an apology as follows:

19 July 2008
The Viscount Monckton of Brenchley
Carie, Rannoch, PH17 2QJ, UK
Arthur Bienenstock, Esq., Ph.D.,
President, American Physical Society,

Dear Dr. Bienenstock,
Physics and Society
The editors of Physics and Society, a newsletter of the American Physical Society, invited me to submit a paper for their July 2008 edition explaining why I considered that the warming that might be expected from anthropogenic enrichment of the atmosphere with carbon dioxide might be significantly less than the IPCC imagines.
I very much appreciated this courteous offer, and submitted a paper. The commissioning editor referred it to his colleague, who subjected it to a thorough and competent scientific review. I was delighted to accede to all of the reviewer’s requests for revision (see the attached reconciliation sheet). Most revisions were intended to clarify for physicists who were not climatologists the method by which the IPCC evaluates climate sensitivity – a method which the IPCC does not itself clearly or fully explain. The paper was duly published, immediately after a paper by other authors setting out the IPCC’s viewpoint. Some days later, however, without my knowledge or consent, the following appeared, in red, above the text of my paper as published on the website of Physics and Society:
“The following article has not undergone any scientific peer review. Its conclusions are in disagreement with the overwhelming opinion of the world scientific community. The Council of the American Physical Society disagrees with this article’s conclusions.”
This seems discourteous. I had been invited to submit the paper; I had submitted it; an eminent Professor of Physics had then scientifically reviewed it in meticulous detail; I had revised it at all points requested, and in the manner requested; the editors had accepted and published the reviewed and revised draft (some 3000 words longer than the original) and I had expended considerable labor, without having been offered or having requested any honorarium.
Please either remove the offending red-flag text at once or let me have the name and qualifications of the member of the Council or advisor to it who considered my paper before the Council ordered the offending text to be posted above my paper; a copy of this rapporteur’s findings and ratio decidendi; the date of the Council meeting at which the findings were presented; a copy of the minutes of the discussion; and a copy of the text of the Council’s decision, together with the names of those
present at the meeting. If the Council has not scientifically evaluated or formally considered my paper, may I ask with what credible scientific justification, and on whose authority, the offending text asserts primo, that the paper had not been scientifically reviewed when it had; secundo, that its conclusions disagree with what is said (on no evidence) to be the “overwhelming opinion of the world scientific community”; and, tertio, that “The Council of the American Physical Society disagrees with this article’s conclusions”? Which of my conclusions does the Council disagree with, and on what scientific grounds (if any)?
Having regard to the circumstances, surely the Council owes me an apology?
Yours truly,
THE VISCOUNT MONCKTON OF BRENCHLEY
———————————–
Monckton’s demand for redress and an apology from the APS is being picked up on the internet.
How will the American Physical Society respond to Lord Monckton’s procedural and scientific gauntlets?
As of noon on Saturday July 20, 2008, the offending paragraph in the table of contents had been removed. However, this offending paragraph was still very much evident in Monckton’s paper Climate Sensitivity Revisited. It was also evident in the Forum’s full PDF of its July, 2008 newsletter Physics and Society Vol 37, No 3, p 6.
The APS’s PeerGate scandal may well prove to provide much greater publicity and serious examination of Monckton’s thesis than if the disclaimers had never been posted. It also exposes the superficiality of statements by executives of the American Physical Society and other scientific organizations supporting the IPCC’s global warming. Those statements were typically not submitted to the rank and file for scientific peer review, nor were they typically voted on by the rank and file. Whatever will come out of this PeerGate Scandal?

The disclaimer-
The Council of the American Physical Society disagrees with this article’s conclusions.
The conclusions they disagree with –
In short, we must get the science right, or we shall get the policy wrong. If the concluding equation in this analysis (Eqn. 30) is correct, the IPCC’s estimates of climate sensitivity must have been very much exaggerated. There may, therefore, be a good reason why, contrary to the projections of the models on which the IPCC relies, temperatures have not risen for a decade and have been falling since the phase-transition in global temperature trends that occurred in late 2001. Perhaps real-world climate sensitivity is very much below the IPCC’s estimates. Perhaps, therefore, there is no “climate crisis” at all. At present, then, in policy terms there is no case for doing anything. The correct policy approach to a non-problem is to have the courage to do nothing.
Whoever wrote the disclaimer may not have even read the conclusions.

You might clarify which statements came from Lord Monckton, which from Robert Ferguson and which by “Staff”.
As ’tis said: “There’s many a slip between the cup and the lip”.
On “Scientific Peer Review”
Per numerous web comments regarding Monckton’s paper, it would help to recognize the numerous gradations in “scientific peer review”.
1) Newsletters
The Forum for Physics and Society is apparently an APS quarterly Newsletter which has at least editorial feedback from the co-editor. e.g.
http://scienceandpublicpolicy.org/images/stories/papers/monckton/monkton_letter_pys.pdf“> comments by Editor Prof. Alvin Saperstein. Here the Editor has general knowledge of the field but may not be expert in that specialty.
By the way, the editors appear to have been generous to the “minority” position in accepting Lord Monckton’s 8000 word article when the normal criteria is: “Contributed articles (up to 2500 words, technicalities are encouraged) . . .are welcome”.
2) Conference Papers
Speaking from experience with another professional society, professional society conference papers, peer review from at least three reviewers within the specialty field are typically required.
3) Journals
Then a small portion of refined and presented papers are judged of sufficient quality and originality to be submitted for the organizations Transactions or Journals.
4) Critical examination
The next level is critical evaluation by the likes of Steven McIntyre of Climate Audit. e.g., McIntyre & McKitrick’s 2003 evaluation of
Mann et al. 1998. i.e., by those who have the time and passion to analyze the equations, verify the results and logic etc.
5) National review
From there one “graduates” to a full court national level review such as the Wedgman Report which systematically critiques the report in detail by the experts in the field.
Each of these can be said to have had some level of “scientific peer review”. Yet there is often an order of magnitude difference in effort between each of these levels.

I do agree that: He egregiously misrepresented the matter in the SPPI press release.
Still I think the APS should not mislead the public by pointing out only his paper was not “scientifically” peer reviewed. Its not a matter of finer feelings; its a matter of confusion for the world. Clearly the paper was reviewed ( and frankly whether it was or not doesn’t matter, because people would argue after the fact), and for the APS to declare that their own editor was not doing a scientific review is a bit confusing to all, and at the same time state that the paper was incorrect if it hadn’t been scientifically reviewed is also a bit confusing.
Let me ask a science question: “They certainly don’t say that the atmosphere absorbs all IR.” actually this was one of their limit values to determine a temperature( I think) and they make this assumption in a derivation.
my question is: what did I read wrongly? I freely admit I could have missed this point but I did think it was a limit term
Some more elementary questions and confusion I have as an outsider:
why doesn’t hoffmeister include heat capacity terms in their extra added wattts/meter sq . The atmosphere is being treated like its an adiabatic system: it isnt.
whenever we burn fuel or make electricity , terrawatts of heat are given off and this heat is never a parameter in any model which contributes a c02 like term to temperature change. I dont know enough to know where it would enter: it could be additive to a co2 effect or it could simply be a reason for increased warmth: a global heat island effect.
Further more the heat capacity of the oceans and the land and dirt in the air are never used to determine the temperature effects of the calculated forcing.
Lets say you have an extra 4 watts per meter sq insolation equivalent. but also lets say that that 4 watts is going into a body that has an infinite heat capacity like a section through the crust or a section into the ocean. What does that do to the temperature? if its infinite, the answer is that the forcing doesn’t affect the temperature. So you need a heat capacity term
Please also consider that if a “global heat island effect” doesn’t contribute to a warmer earth as has been suggested by reviews of some papers, why? where does all that heat go? Could the lack of a global heat island effect be an actual measure of the useful heat capacity of the earth and water and could be used to calculate the temp change from a co2 forcing?
APS Amendment
As of Monday July 21, 2008 at 1:20 pm, theAmerican Physical Society has amended is red letter disclamation on Christopher Monckton’s article Climate Sensitivity Revisited
FROM:
The following article has not undergone any scientific peer review. Its conclusions are in disagreement with the overwhelming opinion of the world scientific community. The Council of the American Physical Society disagrees with this article’s conclusions.
TO:
The following article has not undergone any scientific peer review, since that is not normal procedure for American Physical Society newsletters. The American Physical Society reaffirms the following position on climate change, adopted by its governing body, the APS Council, on November 18, 2007: “Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth’s climate.
The editors have backed down on Lord Monckton’s 2nd and 3rd requests regarding the Council’s decision by passively restating the Council’s policy.
Retaining the comment “The following article has not undergone any scientific peer review,” still appears unfortunate considering the degrees of peer review noted above.
(PS The combined July 2008 newsletter has not yet been modified. Nor have any comments been added to the “pro” climate change paper:
A Tutorial on the Basic Physics of Climate Change)

Some more elementary questions and confusion I have as an outsider:
why doesn’t hoffmeister include heat capacity terms in their extra added wattts/meter sq forcing equations?. The atmosphere is being treated like its an adiabatic system: it isnt. It may be that they are only trying to calculate an energy effect purely for c02 and not calculate the effect of the extra energy on temp.
whenever we burn fuel or make electricity , terrawatts of heat are given off and this heat is never a parameter in any model which contributes a c02 like term to temperature change. I dont know enough to know where it would enter: it could be additive to a co2 effect on temp or it could simply be a reason for the increased warmth that is not from c02: a global heat island effect. whatever effect this terrawatts of energy term has on temp, it would subtract the observed co2 effect on temp
Further more the heat capacity of the oceans and the land and dirt in the air are never used to determine the temperature effects of the calculated forcing by co2.
Lets say you have an extra 4 watts per meter sq insolation equivalent. but also lets say that that 4 watts is going into a body that has an infinite heat capacity like a section through the crust or a section into the ocean. What does that do to the temperature? if its infinite, the answer is that the forcing doesn’t affect the temperature. So you need a heat capacity term for consideration of a non infinite heat capacity
Please also consider that if a “global heat island effect” doesn’t contribute to a warmer earth as has been suggested by reviews of some papers, why? where does all that heat go? Could the lack of a global heat island effect be an actual measure of the useful heat capacity of the earth and water and could be used to calculate the temp change from a co2 forcing?
That the APS is officially behind the “science” of AGW ought to scandalize everyone of its members.
I would like to say once more that this “forcing” definition used by climatologists is unfortunate. It is almost true that a heavenly body receives and sends energy through electromagnetic radiation. ( almost because gravitational energy is also exchanged between heavenly bodies). At the level of the outer surface of the earth radiation balance and energy balance are almost the same.
The unfortunate thing is that people using this “forcing” business forget that radiation is not conserved. It is energy that is the conserved quantity, and energy takes many forms, from heat to convection , to evaporation and precipitation. Of course heat capacities are very important. This is a a complex, chaotic, thermodynamic system one has under study, from coupled differential equations.
These “forcings”are like making a budget, using only cash flow and ignoring credit and debt, or at best “estimating” by a computer model the average credit and debt for a business.
Re: limiting assumptions.
“the atmosphere absorbs all IR”, blackbody absorption by the earth are limiting assumptions. I expect heat capacity can also be ignored in the limit of modeling the equilibrium system to approximate long term changes. (Each of these needs to be modified in refining models to dynamic conditions.) See references above to Miskolczi’s greenhouse theory.
The APS decides to play fair
The American Physical Society has decided to play fair and post the identical disclaimer to BOTH Hafemeister & Schwartz’s Pro article and Monckton’s Con article in its current global warming debate, namely:
PS. These corrections have not yet been propagated to the entire July 2008 Forum on Physics and Society Newsletter pdf.
The APS has posted the following disclaimer on its Forum for Physics and Society July 2008 Newsletter
(h/t to Michael S. Talcott)
Hi peer reviewer… the APS has now added a disclaimer on top of the tutorial paper as well, to point out that there is no peer review on any of the papers.
The tutorial paper — which seems mostly fine to me, albeit limited in scope — goes through a sequence of examples.
(1) Upper atmosphere temperature using blackbody emission.
(2) Using Ts — a fraction of IR that should be absorbed to account for higher surface temperatures. Requires atmosphere to absorb 0.76 of IR.
(3) Using Ta and Ts — an atmospheric emissivity value to account for higher surface temperatures. Effectively the same as (2); emissivity is 0.76. Note from Kirchoff’s law that IR emissivity = IR absorptivity; so again, 0.76 of IR is absorbed.
(4) Using a “multi layer” atmosphere; where each layer is treated as a fully absorbing blackbody. Earth has 0.6 of a layer… again, less than the 1 for full absorption. But you need this to get a good comparison with Venus.
They do also give the limit for complete absorption; but that is nothing to do with Earth. It is only there as an illustration of how the simple model behaves in a thicker atmosphere.
As for heat capacity, this is a subtle point, and beyond the scope of the tutorial. It’s irrelevant for an equilibrium analysis, since at equilibrium you have all your heat reservoirs in balance with each other. The effect of a heat reservoir (the ocean is the big one) that it takes a long time to reach the equilibrium when everything is held fixed. And if things are not held fixed, then you basically have damping. It’s certainly important in a more complete analysis; but this tutorial is only the first step, and increasing complexity generally leaves heat capacities until after a few more complexities are introduced.
What it means for us at present is that since the Earth (for whatever reason you care to attribute) is warming; and that is coming from extra energy somewhere. As the Earth warms, it emits more longwave radiation; and this is basically the response to compensate for some energy imbalance. But there’s also heat being taken up into the ocean, and heat going into the ocean is not going out into space. This actually means there is a slight imbalance of energy at present. As the ocean “catches up” with surface temperatures, the rate of flux into the ocean drops, and then extra energy leads to a warmer surface and more energy into space. So whatever is warming earth right now, some of that warming is a heat flux into the ocean, and yet to be realized as a temperature rise. Estimates vary, but there’s probably something like another half a degree of warming that is due when the ocean comes up into equilibrium, even if nothing else changes The heat capacity of the ocean is finite; and the time lag is measured in decades, I think.
A full analysis of the heat transfers deals with convection and also with latent heat, which is energy transfered by water vapour rising into the atmosphere and then condensing. You can manage this with a “pseudo-adiabat”. The nice thing is, however, that it doesn’t actually make a lot of difference to the analysis of the tutorial.
If you look closely at the tutorial, you’ll see showing up a factor of 2^0.25 difference in temperature between surface and atmosphere. This is a real effect, and it is what gives us a troposphere. Radiation alone would mean the atmosphere was cooler than the surface, even right at the point of contact. The means convection and latent heat tend to transfer energy up from the surface, and up until everything comes into balance with radiation again… which is basically the tropopause, above which the atmosphere is no longer turbulent and convection no longer has a significant role. So it is still heat from surface to lower atmosphere, and really doesn’t alter the simple level of analysis in the tutorial how the energy gets there.
And, by the way… for “anna v”, this is why forcing is only defined above the tropopause. The energy into and out of the Earth above this level is pretty much all by radiation.
As for waste heat… global energy consumption is around 13 TeraWatts or so. For Earth’s surface of 5.15e14 m^2 that works out to about 0.025 W/m^2, which is pretty negligible in the energy balances for climate.

Re: David L. Hagen (10:32:56)
As noted in above comment, the new statement, no longer is red, now appears:
The following article has not undergone any scientific peer review, since that is not normal procedure for American Physical Society newsletters. The American Physical Society reaffirms the following position on climate change, adopted by its governing body, the APS Council, on November 18, 2007: “Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth’s climate.”
The newsletter from the Forum on Physics and Society (pdf version) has now undergone yet another revision. The above statement now appears in regular black type at the head of both articles.
Bottom line… the forum will continue the discussion. This is good news.
hi,
I need to reread the section with complete absorbtion: ( a double entendre) I thought it was key to obtaining a temp value ……….
another reason I think about heat capacity issues is that they allow cumulative energy transfers, essentialy slow flows. take the .o25 watts for burning things which doesnt seem to be much but in ten years its .25 watts and in 40 years its 1 watt/m^2. so its heat added to the system. Ask yourself: if you were to forget c02 but integrate heat evolved since 1750 what temperature would you get? do we have a measure of the heat capacity of the earth and ocean and how they transform energy into other events which do not affect temperature?
Other notions: a black body radiator is really not such a good model. ( I dont mean the atmospheric approximations or the top of the atmosphere, I mean the whole system) No black body had insulated molten metal swirling around in it, with volcanoes under the artic and antartic. And is mass accounted for in black body radiators? I thought they were usually dimensionless point sources? are chemical reactions allowed ( no) I know its easy to say well for a first approximation…..
And the equilibrium model is just not right because we are in deed not in equilibrium. In fact the whole question of global warming is how far are we away from equilibrium. Are there relaxation methods employed to deal with this ( they are used for certain biochemical processes away from equilibrium, stop flow experiments)?
finally the heat goes somewhere and does some things: the ocean currents have enormous energy, partially driven by undersea vents, and the earth spins and the wind blows and enormous chemical reactions occur and use energy which no one ever thinks about. has anyone measured the time of day length and seen whether it is changing?. And then there is the moving magnetic pole: how much energy does it take to do this, and how much magnetic energy is loss to space as radiation, or is it?
sorry for all the questions and maybe I dont know all the basics for the assumptions, but I would like to lay bare all the “givens” used in discussing the problem
PS johnathan drakes page in the UK has a tongue in cheek graph which shows rate of change of magnetic north pole tracks very well with temperature from Hadley and is much better than co2 if you like correlations
Lord Monckton responds via email to Michael Kellman’s email above:
The APS’s Forum on Physics and Society Newsletter already has an extraordinary disclaimer on its July 2008 newsletter cover (See above). It would make eminent sense to remove the extremely unusual dislamations from the top of each of the articles submitted in this greenhouse debate.
Now will politics or common sense win in this debate over the “science”?
I think Hafemeister’s tutorial was quite interesting to start with AGW theory.
The critical and disputed part of his tutorial appears to be included in a single sentence, that he presented without referencing:
“One can attribute 21 oC of that warming to the IR trapping of water vapor, 7 oC to CO2 and 5 oC to other gases.”
I think this is a spectacular contribution for such a rare trace gas.
An Open Question To Global Warming Alarmists
Isn’t it logical to take action against Global Warning (GW) only if the following four conditions are met?
(1) GW is in fact occurring. If GW is just so much “hot air” (pun intended), then GW is a nonissue–or more correctly, a nonexistent issue.
(2) In the aggregate GW is harmful to mankind. I know in this age of political correctness, it’s deplorable to express little or no concern for the world’s plants and animals; but I do, at least when compared to my concern for mankind. For example, if mankind had the power to change the environment in a way that benefited all mankind but resulted in the extinction of polar bears, I’d say go for it. After all, aren’t we doing something similar by attempting to eradicate the smallpox virus from the face of the earth? Environmentalists can’t in good conscience make the claim: “We can’t allow polar bears to become extinct because (a) it’s immoral for man to abet the extinction of a life form, and (b) the extinction of the polar bear will hurt the environment,” unless they are willing to make a similar claim about the smallpox virus. The smallpox virus is a living organism too; and by eradicating smallpox the number of the worst polluter (humans, according to many environmentalists) on the face of the earth will increase. Thus, by eradicating smallpox we are destroying a life form and making a big impact to the environment. The main difference I see between smallpox and polar bears is that young polar bears are cute; and hence telling children that the number of polar bears is decreasing brings tears of sadness not tears of joy as would happen if we tell them smallpox is becoming extinct. Once full grown, polar bears can be very dangerous. None of my friends is a polar bear, and I don’t really care what happens to them (polar bears)–good or bad. I’m not looking to harm them, but I also don’t want to spend much effort to ensure they are around when the sun becomes a red giant. So, if in the aggregate GW is beneficial to man (and I can think of at least one possible reason why it might be–a warmer climate might allow for increased production of foodstuff), then I want more, not less, GW.
(3) There is something we can do about GW. Even if (a) GW is occurring, and (b) in the aggregate it is harmful to mankind, I’m not going to worry about it if we can’t do anything about it. Just like I don’t lose sleep over the fact that the Yellowstone Caldera might erupt like it has in the past. I will listen to discussions about how to adapt to GW; but if we can’t affect it, why listen to arguments on how to stop it?
(4) What we do about GW is less harmful to mankind than GW itself. Even if (a) GW is occurring, (b) in the aggregate it is harmful to mankind, and (c) there is something we can do about it, before we take action I want to be sure that the action we take doesn’t cause more harm to mankind than allowing GW to proceed unhindered. Let’s postulate (1), (2), and (3) above are true, and throw in for good measure that man’s industrial activity is the major contributor to GW. One way to solve the problem, at least temporarily, would be to liquidate 99% of all humans now living on the earth. If I’m in the 1% who are allowed to live, it’s unlikely but conceivable that I’d go along with such a solution; but if I’m in the 99% who get sacrificed to the altar of Al Gore, then I’d just as soon ignore GW and let the chips fall where they may.
When I hear GW discussed in the main-stream media, I’m pretty sure it’s just so much “feelsuperiorism” in the sense that those who advocate doing something about GW can feel superior to us skeptics because they’re onboard the glory train to save the world by stopping the scourge of GW and we’re tearing up the tracks in front of them. The possibility that (a) the GW alarmist train doesn’t have an engine or (b) the light at the end of the tunnel is another train, not the tunnel exit, doesn’t appear to have entered the minds of GW alarmists. As such, I have a tendency to ignore the main-stream media’s propaganda about GW, and consequently have heard only a miniscule fraction of their discussion. However, in the portion I have heard, the four conditions above have never been discussed collectively, much less proven.
In closing, my father often related to me what his father told him: “Son, the world is full of people who know things that aren’t true.” It’s my perception that Al Gore, the main-stream media, and much of the western world “know GW is here, know it is harmful, and know that we can do something about it.” In my opinion, such knowledge is an illustration of my grandfather’s claim.
Add to Reed Coray’s post:
(5) What are relative benefits/costs of combating GW vs other major global problems?
The Copenhagen Consensus puts stabilizing climate at the BOTTOM of the list of all major global projects where we could invest put scarce funds.
Per Monckton’s article at APS, there is growing evidence that non-anthropogenic causes dominate climate change, and that there is little we could do about it.
Thus the critical importance of unbiased evaluation of the science without major political interference such as the APS PeerGate peer review scandal.
This is just more censorship by people who are now really starting to worry about their professional reputations.
I post on Real Climate occasionally but most of my posts are censored.
The latest post to ‘vanish’ was one were I pointed to the fact that, the generic response to posters, pointing to the 21st century global temperature et al trends, is to state that theirs and the IPCCs position is that 30 years of a trend are needed before this could be accepted as evidence of climate change. Posters have been told to come back in 2032 before they will be listened to.
I asked therefore, why, when Hansen started spouting off in 1988 about the
sharp warming trend from 1978 to 1988, was he not told to come back in 2008 and then continue the debate. I pointed out that if he had been we would have been able to say, ‘Don’t worry Jim it is currently cooler than when you first raised the subject!’
Tom Klein: Thank you for your post (23:05:51).
For the most part I agree. I sense that you have difficulty relating global warming (GW) models of average Earth Global Temperature to electronic circuit analysis. I know I do. For example, I disagree with the statement “If the product of the two factors is greater than one then you have a system with a net positive feedback.” The 1978 (fourth) edition of the “Markus Electronics Dictionary” (I know, it’s an old edition–but so am I) defines feedback as
“The return of a portion of the output of a circuit or device to its input. With positive feedback, the signal fed back is in phase with the input and increases amplification but may cause oscillation. With negative feedback, the signal fed back is 180 degrees out of phase with the input and decreases amplification but stabilizes circuit performance and tends to minimize noise and distortion.”
Most electronic circuits are designed to operate on a time-varying external input signal. If the output (or a portion of the output) of the circuit is returned to and additively combined with the external input to form a composite input that is the sum of the external component and the returned component, then the circuit is said to be “recursive” or to have “feedback”. [Note: As I understand it, all analog circuits have some amount of feedback. It is only in the digital world that “feed forward” or “nonrecursive” “circuits can be realized.] Thus, associated with a circuit’s feedback are (a) a delay (time interval between an external input and the circuit’s response/feedback to that external input–note that in all recursive circuits the time delay is a function of frequency), and (b) a multiplicative coefficient. If the feedback consists of a single return path from the circuit output and the magnitude of the multiplicative coefficient for that path is equal to or greater than 1, the circuit is theoretically unstable–i.e., for a bounded external input the circuit output will be unbounded. In the real world, unbounded circuit outputs are impossible if for no other reason than they imply the generation of an infinite amount of output power. In practice, some physical process always occurs that changes the nature of the circuit, which is a good thing, otherwise we’d all be toast).
I see at least two problems with attempts to apply electronic circuitry analysis to global warming (GW) models. First, in all the GW literature that I’ve seen (which, by the way, is miniscule), I haven’t come across a description of a time-varying external input. This leads me to the conclusion that GW scientists are interested primarily in the DC (zero frequency) behavior of the system (the earth’s average global temperature). [By the way, if the DC component is the only component of interest, then for real as opposed to complex inputs positive feedback implies a feedback coefficient greater than 0 {not greater than 1), and negative feedback implies a feedback coefficient less than 0.] Second, and more important, for the GW models that I’ve seen (again, an extremely limited set) the external input to the models and the model feedback don’t have the same physical units. The external input is expressed as power flux density (watts per square meter) at the tropopause (not the temperature at the tropopause) and the feedback is expressed in temperature degrees. To a circuit analyst, this poses a problem. If the earth is treated as a black box with a feedback path, then using “circuit analysis” concepts the units of the external input and the units of the feedback should be the same–either both temperature or both power flux density.
I don’t want to imply that the terms “radiativeforcing”, “no-feedbacks”, “temperature feedbacks” etc., used by the GW community are meritless–I’m sure they are very useful–but I have a problem (most likely due to my limited understanding of GW models) relating these concepts to the tools of electronic circuitry analysis.
Thank you Mr. Hagen (16:30:35) for adding a fifth “required condition” before we try to do something about global warming. I’m sure there are others.

Dear Dr. Bienenstock:
A wise man once said, “When you find yourself at the bottom of a hole, stop digging.” I note that the front page of the Forum on Physics and Society
http://www.aps.org/units/fps/newsletters/200807/ now carries the disclaimer:
So other than the remarkable appearance of such a disclaimer in your newsletter for the first time, its detailed statment of the rather obvious fact that the views expressed are not necessarily those of the Forum Executive Committee, and its restatement of an advocacy position that a clearinghouse scientific body should at no time have made, we find that in the view of the Executive Committee a “considerable presence within the scientific community of people who do not agree with the IPCC conclusion…” simply does not exist! To whom do you then attribute these views and the hundreds of papers that have appeared in many different major academic refereed journals? Leprechauns?
But please, keep digging, sir. The artifacts you are exhuming are extremely instructive.
