APS Comments on Harold Lewis’ Resignation of his Society Membership

WASHINGTON, D.C. — In a recent letter to American Physical Society (APS) President Curtis A. Callan, chair of the Princeton University Physics Department, Harold Lewis, emeritus physics professor at the University of California, Santa Barbara, announced that he was resigning his APS membership.

In response to numerous accusations in the letter, APS issues the following statement:

There is no truth to Dr. Lewis’ assertion that APS policy statements are driven by financial gain. To the contrary, as a membership organization of more than 48,000 physicists,  APS adheres to rigorous ethical standards in developing its statements.

We know that the existing 2007 APS Statement on Climate Change was developed literally over lunch by a few people, after the duly constituted Committee had signed off on a more moderate Statement.

The Society is open to review of its statements if members petition the APS Council – the Society’s democratically elected governing body – to do so.

We have yet to receive a response to our Petition:

http://www.openletter-globalwarming.info/Site/Signatures__APS_Council_Study.html

…delivered last spring and signed by 260+ members and former members,  including nearly 100 Fellows, 17 members of national academies and 2 Nobels. Driven largely by the ClimateGate revelations, the Petition asks that the Society conduct an independent study and assessment.

As for democratic membership participation in matters of science, consider the reaction to a grass roots outpouring of APS member opinion on the 2007 APS Statement http://www.aps.org/publications/apsnews/200912/apscouncilors.cfm .  “[APS Councilor] was uncomfortable with the idea of a membership-wide referendum on statements. He said that he was concerned that having a membership wide vote on controversial issues could lead to the adoption of scientifically unsound statements.”   Evidently physicists should be excluded from inputting on a question of physics; only “physics monks” are entitled to do so ex cathedra .

Dr. Lewis’ specific charge that APS as an organization is benefitting financially from climate change funding is equally false.  Neither the operating officers nor the elected leaders of the Society have a monetary stake in such funding.

The chair of the Panel on Public Affairs (POPA) that re-endorsed the 2007 APS Statement on Climate Change sits on the science advisory board of a large international bank http://annualreport.deutsche-bank.com/2009/ar/supplementaryinformation/advisoryboards.html The bank has a $60+ billion Green portfolio, which it wishes to assure investors is safe…not to mention their income from carbon trading.  Other members of this board include current IPCC chief Pachauri and Lord Oxburgh, of Climategate exoneration fame.  The viability of these banks activities depends on continued concern over CO2 emissions .  Then there is the member of the Kleppner Committee (that reviewed the APS 2007 Statement prior to POPA) who served on that committee while  under consideration for the position of Chief Scientist at BP.  The position had been vacated when Steve Koonin left to take a post in the administration at DOE. Soon after the Kleppner Committee report in late 2009, this committee member took the BP job. BP had previously funded the new Energy Laboratory at Berkeley, which was headed by current Energy Secretary Steve Chu.

Moreover, relatively few APS members conduct climate change research, and therefore the vast majority of the Society’s members derive no personal benefit from such research support.

This does not mention the firm expectation by federal government agencies such as the NAS and the Presidential Science Advisor’s office that the APS will continue to support the huge funding machine that diverts billions of taxpayer dollars into research that must support the alarmist credo. APS has been silent on the documented practice by some climate scientists aimed at preventing opposing research from being published.

On the matter of global climate change, APS notes that virtually all reputable scientists agree with the following observations:

  • Carbon dioxide is increasing in the atmosphere due to human activity;
  • Carbon dioxide is an excellent infrared absorber, and therefore, its increasing presence in the atmosphere contributes to global warming; and

This passes over the fact that carbon dioxide absorption lines are nearly saturated.

  • The dwell time of carbon dioxide in the atmosphere is hundreds of years.

Well, it depends on what you mean by “dwell time.”  If it is the conventional half life of an impulse loading of carbon dioxide, the statement is wrong – by a lot..  The IPCC’s Bern carbon cycle model http://www.climate.unibe.ch/~joos/model_description/model_description.html gets a 16 year half life.  If it is the time for the last molecule to get picked up by a sink, the statement is meaningless.  At the very least, the statement is sloppy and hardly befitting a world class scientific society.

On these matters, APS judges the science to be quite clear.  However, APS continues to recognize that climate models are far from adequate, and the extent of global warming and climatic disruptions produced by sustained increases in atmospheric carbon loading remain uncertain.

This is much better than the 2007 APS Statement itself.  However, the phrase “climate disruptions” is noteworthy because it is the new buzzword recently introduced by Science Advisor John Holdren http://blogs.telegraph.co.uk/news/jamesdelingpole/100054012/global-warming-is-dead-long-live-er-global-climate-disruption/ , evidently enabling advocates to assign any unusual weather event to human causes.  It is curious that that the APS press release happens to echo this new phrase.

In light of the significant settled aspects of the science, APS totally rejects Dr. Lewis’ claim that global warming is a “scam” and a “pseudoscientific fraud.”

What we have here is a bait and switch.  No one is saying that the greenhouse effect itself is a scam. This passage seeks to transfer the ‘scam’ charge from its real target to the trivial.  The fraud/scam is to be found in the continual drumbeat that the science is settled; that the effects will be catastrophic; that it requires draconian economic sacrifices to avoid; and that mandates and subsidies for rent-seeking corporations are justified.

Additionally, APS notes that it has taken extraordinary steps to solicit opinions from its membership on climate change.  After receiving significant commentary from APS members, the Society’s Panel on Public Affairs finalized an addendum to the APS climate change statement reaffirming the significance of the issue.  The APS Council overwhelmingly endorsed the reaffirmation.

Never mind that the Panel on Public Affairs is chaired by an individual whose research funding stream (from BP) depends on continued global warming alarm.  And you have to keep your eye on the pea.  The dispute was not over the “significance” of the issue; it was over the alarmist nature of the statement. The addendum used more than five times the number of words to try to explain what the original statement meant.   Not a good sign that they got it right the first time.

Lastly, in response to widespread interest expressed by its members, the APS is in the process of organizing a Topical Group to feature forefront research and to encourage exchange of information on the physics of climate.

Never mind that the Topical Group was proposed in a petition organized by a group of five members that included Dr. Lewis.   Also, the Council has not yet approved a TG; therefore it is not in the process of being “organized.”  It is being considered.   No formal charter or bylaws have been set down. What we have here is the first attempt to co-opt the TG for PR purposes. This before it has even been approved by the APS Council.

Read the APS Climate Change Statement and Commentary:  http://www.aps.org/policy/statements/07_1.cfm.

APS should be very reluctant to draw public attention to this Statement, with its infamous phrase, “The evidence is incontrovertible,” despite the fact that nothing in science is ever incontrovertible.

About APS: The American Physical Society (www.aps.org) is the leading physics organization, representing 48,000 members, including physicists in academia, national laboratories, and industry in the United States and internationally.

Dr. Roger Cohen writes in with an addedum:

I would like to clarify one technical point for your visitors. It relates to: “This passes over the fact that carbon dioxide absorption lines are nearly saturated.”

The statement is fact, but it does not by itself imply that additional amounts of atmospheric CO2 will not cause significant warming. Straightforward radiation transfer calculations have established that the effect of doubling atmospheric CO2 would be to increase global average temperature by only about 1 deg. C. — if there were no other climate effects involved. However, these other effects, generally called “feedbacks,” can amplify or attenuate the primary radiation altering effect of additional CO2. The most prominent feedback is the “cloud-water vapor feedback,” which is very difficult to calculate or determine empirically. The IPCC says these feedback effects are in aggregate large and positive, giving rise to their most recent estimate of 2 to 4.5 deg. C for doubling, with a most likely value of 3 deg. C. However, a substantial body of other research points to a much lower value, much closer to the zero feedback value of 1 deg. C, or even lower. The actual aggregated effect of feedbacks is a critical aspect of the debate.

But Lucy,
The oceans are absorbing CO2 and thus can’t be the source of the increased CO2 in the atmosphere.
What about the carbon isotope studies that show the ration of C13 to C12 has been changing showing that the increase in atmospheric CO2 is due to fossil fuels.
And even the atmospheric concentration of O2 is going down as we burn fossil fuels.
Not to mention pH

Masterful response by APS. Who says scientists aren’t skilled at PR? (sarc)
I can only imagine the inquiries they’re receiving by their membership. It appears they’ve grossly underestimated Dr. Lewis. I can’t think of a more useful or honorable way to end a long and distinguished career. My sincere gratitude to Dr. Lewis and his noble associates.

Seems to me they contradict themselves with this statement:
“However, APS continues to recognize that climate models are far from adequate, and the extent of global warming and climatic disruptions produced by sustained increases in atmospheric carbon loading remain uncertain.”
How can the science of AGW be settled if the models are “far from adequate” and the extent of the impact remains “uncertain”.
Did they even read this before they issued the press release?
To me, this is clearly a smoke screen, as was pointed out by Hal, they are trying to deflect, and twist to draw attention away from the issues that were put forth.
How much more credibility would the APS have had if they had come forth and said “Ok…this has not been handled properly, and we need to start over on our attempts to address this issue.”
Sounds like they were being coached by Joe R.

Dr. Lewis is of course correct in his response –this APS statement is much more mild than the 2007 version he is protesting, which reads in part:
“The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.”
And, yes, that’s an eye-popper from a group of supposedly sober scientists.
The only “incontrovertible” part of that statement is that global warming has been occurring for the last 30 years. . . it’s future magnitude and even a rough idea of the contribution of CO2 to that warming is nowhere near “incontrovertible”.

“As for the rest of it, maybe physicists will start zeroing in on the effects of CO2 from a physics standpoint, using the well known equations on the subject and maybe, just maybe, blow a hole in the entire AGW theory.”

Excellent point. Many phsyicists are questioning it. But, as ususal, their studies arent published in “Nature” or any other pro-AGW journal.
This is one of the best I’ve read.

“the IPCC First 1990 Climate Change Report where, in the opening policymakers summary of the report, the RT is stated to be in the range of 50−200 years, and (largely) on the basis of that, it was also concluded in the report and from subsequent related studies that the current rising level of CO2 was due to combustion of fossil fuels, thus carrying the, now widely accepted, rider that CO2 emissions from combustion should therefore be curbed. However, the actual data in the text of the IPCC report separately states a value of 4 years.

No need to. Every climate scientist assumes that CO2 is randomly distributed throughout Earth’s atmosphere all the way up. It is a straight deduction from the fact that the CO2 molecule is “well mixed.” There is not one single physical hypothesis that describes some natural regularity in the behavior of CO2 in the atmosphere. I dare you to state one – in your own words, as I say to my students.

I’ve got the same question as Bret. Is this true? If so, it’s game over. ANY scientist worth his salt would recognize this and there would be no debate. So I’m guessing, until shown otherwise, that either it isn’t true or is under dispute.

It’s not true, some of the line centers are saturated, but the band as a whole is quite definitely not saturated.

As an environmental engineer for more than 47+ years I have reviewed many experiments and data related to water,wastewater treatment , air pollution control, ground contamination, an other aspects of the environmental condition. When I started look at the issue of Mann-made global warming cause by the “greenhouse gas effect” I asked one question-Where is the creditable experimental data showing that the “greenhouse gas effect exists”? In more than 5 years of asking many universities ,governmental agencies, “scientists?’and the internet , I have yet to get an answer. The closes is three experiments from different source that think they have proved the “greenhouse gas effect” each has at least 3 to 10 scientific faults that show that the experimenters do not know physics. The work of many renown physicist has shown that the “greenhouse gas effect” violates fundamental laws of physics. I have developed an experiment that shows that the “greenhouse gas effect does not exist”
below is a list of references that show that the “ghg effect” and Mann-made global warming is a political hoax.
When the AGW continually using circumstantial evidence instead of real evidence you know they do not have the real thing.

The Hidden Flaw in Greenhouse Theory
By Alan Siddons
from:http://www.americanthinker.com/2010/02/the_hidden_flaw_in_greenhouse.html at March 01, 2010 – 09:10:34 AM CST
The below information was a foot note in the IPCC 4 edition. It is obvious that there was no evidence to prove that the ghg effect exists.
“In the 1860s, physicist John Tyndall recognized the Earth’s natural greenhouse effect and suggested that slight changes in the atmospheric composition could bring about climatic variations. In 1896, a seminal paper by Swedish scientist Svante Arrhenius first speculated that changes in the levels of carbon dioxide in the atmosphere could substantially alter the surface temperature through the greenhouse effect.”
After 1909 when R.W.Wood proved that the understanding of the greenhouse effect was in error and the ghg effect does not exist. After Niels Bohr published his work and receive a Nobel Prize in Physics in 1922. The fantasy of the greenhouse gas effect should have died in 1909 and 1922. Since then it has been shown by several physicists that the concept is a Violation of the Second Law of Thermodynamics.
Obviously the politicians don’t give a dam that they are lying. It fits in with what they do every hour of every day .Especially the current pretend president.
Paraphrasing Albert Einstein after the Publishing of “The Theory of Relativity” –one fact out does 1 million “scientist, 10 billion politicians and 20 billion environmental whachos-that don’t know what” The Second Law of thermodynamics” is.

On Some Flaws in Greenhouse Gas Global Warming
I have just finished reading an excellent article by Alan Siddons called The Hidden Flaw in Greenhouse Theory on American Thinker from way back on 25 February 2010. The article is a little slow in developing, but finishes with a death blow to the usual theory put forth by catastrophic anthropogenic global warming advocates. I intend to explain more concisely what Siddons explained and to add comments of my own in this post which make the deathblow much more gory.
First of all, I am going to enlarge the context of the discussion. The primary source of heat for the surface of the Earth is the radiant energy of the sun. The solar wind of the sun, materials dumped into the atmosphere from space, heat from the deep interior of the earth, and the interplay of changes in the Earth’s magnetic field and the sun’s magnetic field are also contributors of heat, though the sum of these is much less than that from the sun’s radiant energy spectrum of ultraviolet (UV), visible, and infra-red (IR) light. The entire catastrophic greenhouse gas hypothesis ignores effects upon the incident IR portion of this spectrum of light from the sun. This is foolish.
UV light is 11% of the radiant energy from the sun. The UV light variance of 0.5 to 0.8% with the solar cycle is much larger than is the visible light variance of 0.22%. UV light is absorbed throughout the atmosphere, but much still reaches the ground and is absorbed there. The amount of UV radiation absorbed in the upper atmosphere is highly dependent upon the amount of ozone there. The amount of ozone is highly dependent upon the solar wind, CFCs, and volcanic activity. When UV light is more absorbed in the stratosphere than the ground, its surface warming effect is diminished. The absorbed energy is re-emitted as IR radiation and much of that energy is quickly lost to space.
The entire atmosphere is transparent to visible light which is the form of 44% of the radiant energy from the sun, so aside from reflection from clouds and aerosol particles, the visible light reaches the ground or oceans and warms them near their surfaces.
Finally, the IR radiation is not absorbed by nitrogen, oxygen, and argon gases which make up 99% of the atmosphere, so a large fraction of it directly warms the Earth’s surface. Some, is absorbed by the dominant greenhouse gas, water vapor, and small amounts are absorbed by carbon dioxide and other greenhouse gases. The incoming IR radiation absorbed in the atmosphere is less effective in warming the Earth’s surface than is that which is absorbed by the Earth’s surface directly. This is because some this energy absorbed in the atmosphere then is radiated again in the form of IR radiation, but now half or more of that is directed out to space. In other words, more water vapor and CO2 in the atmosphere results in a less effective warming of the surface than does less of these gases with respect to the incoming IR energy from the sun. The greenhouse gases have a cooling effect on the original solar radiance spectrum for the 45% of the solar energy in the form of IR.
In each case, whether UV, visible light, or IR, not all of the radiation of that form striking the Earth’s surface is absorbed. Some fraction is reflected and the fraction is very dependent on whether the ground is covered with snow, plowed earth, grasses, forests, crops, black top, or water. There are two real ways that man does have some effect on the Earth’s temperature. He changes the surface of the earth over a fraction of the 30% of its surface which is land. He also converts fossil and biomass fuels into heat. Compared to the overall natural effects, these man-made effects are small, yet they are probably large compared to the effect of his adding CO2 and methane to the atmosphere.
Wherever the atmosphere is heated, there is transfer of heat. In the outer, very low density atmosphere, the primary means of heat transfer is radiant transfer by IR emission from an energetic molecule or atom, since collisions of molecules and atoms for direct energy transfer are rare. In the denser atmosphere, most energy transfer is due to collisions and the convective flow of masses of warmed air. Near the Earth’s surface, almost all of the energy lost by the warmed surface is due to gas molecules striking the surface and picking up heat and then colliding with other molecules to transfer heat from one to another. Once a body of air is so heated, then masses of warmed molecules are transported upward into the cooler atmosphere at higher altitudes or laterally toward cooler surface areas by convection. Any warmed molecule, most of which are nitrogen, oxygen, and argon will radiate IR radiation. However, no molecule or atom at a low temperature such as that near the Earth’s surface is a very effective energy radiator, since the Stephan-Boltzmann equation depends upon the fourth power of the absolute temperature, which commonly near the Earth’s surface is about 290K. Thus, gas molecule collisions and convection are the very dominant means of heat transfer. These processes on balance cool the surface of the Earth and redistribute some of the heat back into the upper atmosphere and cooler places such as those shaded from the sun or the arctic regions.
The favorite claim of the catastrophic greenhouse gas global warming people is that an increase of carbon dioxide and methane gas in the atmosphere will cause energy radiated into the atmosphere from the ground to be absorbed by these molecules and they will radiate half of it back toward the ground, where that energy will warm the surface again and reduce the cooling due to the ground originally radiating that heat into the atmosphere. According to Alan Siddons, less than 1% of the cooling of the Earth’s surface is due to IR emission of the surface or the gases near the surface. More than 99% is due to direct contact and convection.
Since the dominant source of energy warming the surface of the Earth is the sun, let us do a simple calculation based upon the facts presented above. Let us say that greenhouse gases absorb a fraction f of the incoming IR radiation from the sun, which is 45% of the sun’s incoming energy. Thus the energy absorbed by greenhouse gases from the incoming spectrum of solar energy is 0.45f and a fraction of this, say k is radiated back into space without coming near the surface. NASA says k is 0.5, but it is actually slightly larger than that given that much of this absorption occurs at appreciable altitudes. The total cooling due to greenhouse gases, somewhere in the atmosphere, is now 0.45fk. Of this energy, had it become incident upon the surface as IR radiation, a part would have been reflected rather than absorbed. The fraction that would have been absorbed is q. The net energy then lost to the warming of the surface is then 0.45fkq.
Now, let us suppose that a fraction g of the total energy from the sun is absorbed in the Earth’s surface or in the very lower part of the atmosphere. We know that g is a larger fraction of 1 than is f, since most of the solar radiation does reach the ground, including that part in the IR part of the spectrum. Of the energy g absorbed in the surface, only 0.01 times it is emitted as IR radiation according to Siddons. Since the greenhouse gas content of the atmosphere is unchanged the amount of outgoing radiation, serving to cool the surface, is now 0.01gf. A fraction j of this energy will be emitted by the IR warmed greenhouse gas molecules back toward the ground. NASA has said this fraction is 0.5. Let us then say j is about 0.5. The greenhouse gas warming of the surface due to absorbing IR radiation from the ground would then be about 0.005gfq, where q is the fraction of back-reflected IR radiation that was incident upon the surface and absorbed. Remember that some radiation is reflected.
Now we will compare the greenhouse gas cooling effect upon the incoming solar radiation of 0.45fkq to the re-warming of the surface due to 0.005gfq times the total solar radiant energy. Breaking down the parts:
0.005 is much less than 0.45, in fact it is 0.011 times as large.
f appears in both factors, so the comparative effect is cancellation.
The factor q appears in both the cooling and the warming quantities, so it cancels.
k is somewhat more than 0.5, while g is the surface absorptivity for the entire solar spectrum and is likely to be near 0.7, or quite comparable.
So let us say g and k are an approximate trade-off.
Thus the net cooling effect of greenhouse gases is very greatly dominant because the re-heating effect is approximately 0.01 times the cooling effect.
In sum, using a simple calculation we can approximate the effect of greenhouse gases on the surface temperature of the Earth. It turns out that the cooling effect due to keeping incoming solar IR radiation away from the surface is about 100 times the re-heating effect proclaimed by greenhouse gas alarmists. Now, if the effect were very large in either case, this might be cause for concern. We would likely be better off heating our planet than cooling it. But, then we are heating with land use changes and the release of energy from fossil fuels, so the generation of cooling CO2 may simply be compensating for these other small effects. Much more important to this issue than CO2 and methane is water vapor in any case. So, most of this cooling effect is due to water vapor and only a small part is due to CO2 and methane.
Now, of course so much is going on here that this calculation is but an indicator of the likely net effect of greenhouse gases. A more careful calculation would consider the different weight of IR frequencies in the original spectrum of the sun and in the Earth surface emission spectrum. But, any changes due to these secondary issues are likely to be small compared to a factor of 100. In any case, this calculation makes mincemeat of the usual simple rationale for greenhouse gas warming alarmism. It is insane to focus only on the outgoing IR radiation from the Earth’s surface while ignoring the large part of the sun’s total incident radiation which is IR from the get-go. It is also insane to ignore gas collisions and convection currents as mechanisms for heat transfer.
I used the greenhouse gas term in the presently conventional way, but in reality, all gases when warm radiate IR energy and as pointed out by Alan Siddons, they are all really greenhouse gases. But, here I used the term only for those gases that absorb IR energy.

Since 1980, he has used XPS or ESCA extensively for the analysis of materials properties, often combining XPS and Auger results with those of other techniques such as microscopy, DSC, SEM, FTIR, EXAFS, Rutherford backscattering, electrochemistry, thermogravimetry, SEM, and XRD to solve complex materials problems. He has had a wealth of experience with surface chemical phase identifications, corrosion, battery development, adhesive failures, contamination, electronic packaging, thin film and bulk materials composition, composite interfaces, particle and sintered ceramic surfaces, surface oxidation and degradation, and many other applications of surface analysis. He has served as an officer of the ASTM Committee E-42 on Surface Analysis and an U.S. Expert on several sub-committees of the ISO Technical Committee 201 on Surface Chemical Analysis. He worked for Case Western Reserve University as a post-doctoral fellow, the Dept. of the Navy as a research physicist, and Martin Marietta and Lockheed Martin as a senior scientist before founding AME, Inc. in 1995. Dr. Anderson especially enjoys integrating the results of multiple analytic techniques to solve tough materials problems. He has assembled a team of materials scientists and engineers with complementary skills and experience who all enjoy working together to solve challenging problems. He is or has been a member of AVS, ASM, MRS, ASTM, the Electrochemical Society, ACS, APS, and SAMPE.
PS:As an environmental engineer designing wastewater treatment plants the fact that about 99% of them are biological has slipped by the Environmental Wackos- everyone of them convert waste material in the sewage to CO2 and organic material that is frequently burned producing more CO2. Now if there is so much danger from CO2 do we shut down every sewage treatment plant in the world? What other collateral damage will occur from continuing the lie of greenhouse gas effects and Mann-made global warming. I know of one suicide/murder (family of 5) because the poor soles did not understand that “Mann-made global warming/climate change “is a total hoax/fairy-tale ,lie. Does the World court reside to change AL Gore and other conspirators with complicity to Murder?
The Third world counties are planning to sue the Developed counties for Trillions of Dollars ,E U’s,and Pecos for damages from “Mann-made global warming that does not exist”. The court costs will cause poverty throughout the World except the lawyers and the “climatologist that don’t know what they are talking about.
Will the APS and others reverse their positions to cover their asses?

“Carbon dioxide is an excellent infrared absorber, and therefore, its increasing presence in the atmosphere contributes to global warming; and…”
By the very nature of IR absorption/emission when the radiative temperature is close to the temperature of the gas, the same physical properties that create absorption bands also create emission bands. Good absorber=good emitter, so it is also true to say that:
“Carbon dioxide is an excellent infrared emitter, and therefore, its increasing presence in the atmosphere contributes to global cooling; and…”
QED this noddy science “proves” we are heading to an ice age. Or to be more precise, it proves that those who sprout such nonsense are noddy scientists!

Anthony,
I would like to clarify one technical point for your visitors. It relates to: “This passes over the fact that carbon dioxide absorption lines are nearly saturated.”
The statement is fact, but it does not by itself imply that additional amounts of atmospheric CO2 will not cause significant warming. Straightforward radiation transfer calculations have established that the effect of doubling atmospheric CO2 would be to increase global average temperature by only about 1 deg. C. — if there were no other climate effects involved. However, these other effects, generally called “feedbacks,” can amplify or attenuate the primary radiation altering effect of additional CO2. The most prominent feedback is the “cloud-water vapor feedback,” which is very difficult to calculate or determine empirically. The IPCC says these feedback effects are in aggregate large and positive, giving rise to their most recent estimate of 2 to 4.5 deg. C for doubling, with a most likely value of 3 deg. C. However, a substantial body of other research points to a much lower value, much closer to the zero feedback value of 1 deg. C, or even lower. The actual aggregated effect of feedbacks is a critical aspect of the debate.

If “relatively few APS members conduct climate change research,” then why would you take “extraordinary steps to solicit opinions from its membership on climate change.” Why would you take extraordinary steps to get the opinions of people who don’t seem to be connected to that field? It just rings hollow.

This passes over the fact that carbon dioxide absorption lines are nearly saturated.

If these guys actually believe this, then they don’t need to be in the APS. Perhaps they should pick up a textbook on radiative properties of the atmosphere.

“Moreover, relatively few APS members conduct climate change research, and therefore the vast majority of the Society’s members derive no personal benefit from such research support.”
If so few APS members are involved in climate change research, why the hell is the APS issuing statements on it? It would seem the topic is almost as far from the APS’s purview as it could get.

Bingo! Who needs due diligence and verification when they can jump on the “consensus” bandwagon?!
Also … from the dissenters’ response:

The chair of the Panel on Public Affairs (POPA) that re-endorsed the 2007 APS Statement on Climate Change sits on the science advisory board of a large international bank […] deutschebank.com […] The bank has a $60+ billion Green portfolio, which it wishes to assure investors is safe…not to mention their income from carbon trading.

Hmmm … Deutsche Bank? … Green portfolio? … income from carbon trading?
Well that would certainly explain the need for this recent entry on Ross McKitrick‘s site:

“MISINFORMATION FROM DEUTSCHE BANK: DB just released a report that aims to rebut major skeptic arguments on global warming. Several topics in their report relate to areas I am quite familiar with. I have posted a response that critiques their handling of the hockey stick and the “hide the decline” email.”

From McKitrick’s “Introduction”:

“Deutsche Bank Group has published a report entitled “Climate Change: Addressing the Major Skeptic Arguments.” The document is dated September 2010 and is available online at http://www.dbcca.com/dbcca/EN/_media/DBCCAColumbiaSkepticPaper090710.pdf.
“The authors are Mary-Ellen Carr, Robert F. Anderson and Kate Brash, all of Columbia University, and the report is published under the imprimatur of the Deutsche Bank Climate Change Advisors, Deutsche Bank Group.
[…]
“Readers who are familiar with the various issues will recognize that the Deutsche Bank (DB) report is one-sided. The weakness of its argumentation is partly due to its failure to properly quote the material it purports to rebut, so that its arguments are frequently shallow and unconvincing. In this rejoinder I will focus only on two items: The Hockey Stick controversy and the report’s treatment of the “Hide the
Decline” email. These should suffice to illustrate the weakness of the DB report.”

The alarmists appear to be going from weakness to greater weakness. They’re reducing themselves to the status of re-branding mahine in perpetual motion!

“Here is the thing. Now that the body of science is publically starting to openly police itself in this Dr. Lewis vs. APS situation, you are critical of it.”
I’m not critical of Dr Lewis at all. He has every right to resign and publish his reasons for doing so. I may not lend any particular weight to that act but that’s a different issue.
However he has leveled a specific charge which was that members of the APS were benefiting financially from climate change research. The response from the APS is their members aren’t involved in climate change research.
The response here, that I was responding to, was “Well why is climate change anything to do with them?”. An obvious question this raises is how much involvement in climate change research entitles a body to comment on climate change versus how much invalidates their opinion because they’re being corrupted by the money involved. Is it possible there exists any organisation anywhere both relevant and expert enough to render an opinion while not having the perception of corruption? Based on the comments here (in which the APS is simultaneously accused of both) I guess not.
“Therefore, you do appear to be against anything critical of the consensus/settled science of AGW by CO2 whether by public processes of science slef-policing or external to science legal policing.”
I’m not “against” any type of criticism however if someone levels criticism in the form of “You’re making trillions of dollars off this” then I think that’s very silly and easily debunked criticism. If one person levels a criticism in the form of “The APS has nothing to do with climate change and shouldn’t issue a statement/isn’t expert enough to have an opinion” while another levels a criticism of “The APS won’t criticism climate change because they get too much money from it” then I find it hard to reconcile those into a coherent argument.
Asking people to explain their criticisms is not being “against” them. Asking for evidence to support criticisms is not being “against” them.
“I think that makes you, by definition, biased by advocacy.
To use your own argument, you would think that in a random selection of your views there would be something critical of the consensus/settled science of AGW by CO2. Is there?”

Sure I can cheerfully tell you that issues around data availability should have been resolved at least a decade ago. I think all the pertinent data should be completely available along with whatever is needed to process it and use it reproduce results. If we use GISS as an example several people have performed their own reconstructions and demonstrated that the reported temperature trends are real (as in real in the data) and not an artifact of “adjustments” as asserted sometimes. The availability of the data and methods strengthens the science and strengthens the confidence in the methods used.
