Guest post by Bill Gray Professor Emeritus, Colorado State University
(AMS Fellow, Charney Award recipient, and over 50-year member)
June 2011
I am very disappointed at the downward path the AMS has been following for the last 10-15 years in its advocacy of the Anthropogenic Global Warming (AGW) hypothesis. The society has officially taken a position many of us AMS members do not agree with. We believe that humans are having little or no significant influence on the global climate and that the many Global Circulation Climate Model (GCMs) results and the four IPCC reports do not realistically give accurate future projections. To take this position which so many of its members do not necessarily agree with shows that the AMS is following more of a political than a scientific agenda.
The AMS Executive Director Keith Seitter and the other AMS higher-ups and the Council have not shown the scientific maturity and wisdom we would expect of our AMS leaders. I question whether they know just how far off-track the AMS has strayed since they foolishly took such a strong pro-AGW stance.
The American Meteorological Society (AMS) was founded in 1919 as an organization dedicated to advancing scientific knowledge of weather and climate. It has been a wonderful beacon for fostering new understanding of how the atmosphere and oceans function. But this strong positive image is now becoming tarnished as a result of the AMS leadership’s capitulating to the lobby of the climate modelers and to the outside environmental and political pressure groups who wish to use the current AMS position on AGW to help justify the promotion of their own special interests. The effectiveness of the AMS as an objective scientific organization is being greatly compromised.
We AMS members have allowed a small group of AMS administrators, climate modelers, and CO2 warming sympathizers to maneuver the internal workings of our society to support AGW policies irrespective of what our rank-and-file members might think. This small organized group of AGW sympathizers has indeed hijacked our society.
The AMS should be acting as a facilitator for the scientific debate on the pro and con aspects of the AGW hypothesis, not to take a side in the issue. The AMS has not held the type of open and honest scientific debates on the AGW hypothesis which they should have. Why have they dodged open discussion on such an important issue? I’ve been told that the American Economic Society does not take sides on controversial economic issues but acts primarily to help in stimulating back and forth discussion. This is what the AMS should have been doing but haven’t.
James Hansen’s predictions of global warming made before the Senate in 1988 are turning out to be very much less than he had projected. He cannot explain why there has been no significant global warming over the last 10-12 years.
Many of us AMS members believe that the modest global warming we have observed is of natural origin and due to multi-decadal and multi-century changes in the globe’s deep ocean circulation resulting from salinity variations. These changes are not associated with CO2 increases. Most of the GCM modelers have little experience in practical meteorology. They do not realize that the strongly chaotic nature of the atmosphere-ocean climate system does not allow for skillful initial value numerical climate prediction. The GCM simulations are badly flawed in at least two fundamental ways:
- Their upper tropospheric water vapor feedback loop is grossly wrong. They assume that increases in atmospheric CO2 will cause large upper-tropospheric water vapor increases which are very unrealistic. Most of their model warming follows from these invalid water vapor assumptions. Their handlings of rainfall processes are quite inadequate.
- They lack an understanding and treatment of the fundamental role of the deep ocean circulation (i.e. Meridional Overturning Circulation – MOC) and how the changing ocean circulation (driven by salinity variations) can bring about wind, rainfall, and surface temperature changes independent of radiation and greenhouse gas changes. These ocean processes are not properly incorporated in their models. They assume the physics of global warming is entirely a product of radiation changes and radiation feedback processes. They neglect variations in global evaporation which is more related to surface wind speed and ocean minus surface and air temperature differences. These are major deficiencies.
The Modelers’ Free Ride. It is surprising that GCMs have been able to get away with their unrealistic modeling efforts for so long. One explanation is that they have received strong support from Senator/Vice President Al Gore and other politicians who for over three decades have attempted to make political capital out of increasing CO2 measurements. Another reason is the many environmental and political groups (including the mainstream media) have been eager to use the GCM climate results as justification to push their own special interests that are able to fly under the global warming banner. A third explanation is that they have not been challenged by their peer climate modeling groups who apparently have seen possibilities for similar research grant support and publicity by copying Hansen and the earlier GCM modelers.
I anticipate that we are going to experience a modest naturally-driven global cooling over the next 15-20 years. This will be similar to the weak global cooling that occurred between the early-1940s and the mid-1970s. It is to be noted that CO2 amounts were also rising during this earlier cooling period which were opposite to the expected CO2-temperature association.
An expected 15-20 year cooling will occur (in my view) because of the current strong ocean Meridional Overturning Circulation (MOC) that has now been established in the last decade and a half and ought to continue for another couple of decades. I explain most of the last century and-a-half general global warming since the mid-1800s (start of the industrial revolution) to be a result of a long multi-century slowdown in the ocean’s MOC circulation. Increases of CO2 could have contributed only a small fraction (0.1-0.2oC) of the roughly ~ 0.7oC surface warming that has been observed since 1850. Natural processes have had to have been responsible for most of the observed warming over the last century and a half.
Debate. The AMS is the most relevant of our country’s scientific societies as regards to its members having the most extensive scientific and technical background in meteorology and climate. It should have been a leader in helping to adjudicate the claims of the AGW advocates and their skeptical critics. Our country’s Anglo-Saxon derived legal system is based on the idea that the best way to get to the truth is to have opposite sides of a continuous issue present their differing views in open debate before a non partisan jury. Nothing like this has happened with regards to the AGW issue. Instead of organizing meetings with free and open debates on the basic physics and the likelihood of AGW induced climate changes, the leaders of the society (with the backing of the society’s AGW enthusiasts) have chosen to fully trust the climate models and deliberately avoid open debate on this issue. I know of no AMS sponsored conference where the AGW hypothesis has been given open and free discussion. For a long time I have wanted a forum to express my skepticism of the AGW hypothesis. No such opportunities ever came within the AMS framework. Attempts at publication of my skeptic views have been difficult. One rejection stated that I was too far out of the mainstream thinking. Another that my ideas had already been discredited. A number of AGW skeptics have told me they have had similar experiences.
The climate modelers and their supporters deny the need for open debate of the AGW question on the grounds that the issue has already been settled by their model results. They have taken this view because they know that the physics within their models and the long range of their forecast periods will likely not to be able to withstand knowledgeable and impartial review. They simply will not debate the issue. As a defense against criticism they have resorted to a general denigration of those of us who do not support their AGW hypothesis. AGW skeptics are sometimes tagged (I have been) as no longer being credible scientists. Skeptics are often denounced as tools of the fossil-fuel industry. A type of McCarthyism against AGW skeptics has been in display for a number of years.
Recent AMS Awardees. Since 2000 the AMS has awarded its annual highest award (Rossby Research Medal) to the following AGW advocates or AGW sympathizers; Susan Solomon (00), V. Ramanathan (02), Peter Webster (04), Jagadish Shukla (05), Kerry Emanuel (07), Isaac Held (08) and James Hansen (09). Its second highest award (Charney Award) has gone to AGW warming advocates or sympathizers; Kevin Trenberth (00), Rich Rotunno (04), Graeme Stephens (05) Robert D. Cess (06), Allan Betts (07), Gerald North (08) and Warren Washington and Gerald Meehl (09). And the other Rossby and Charney awardees during this period are not known to be critics of the AGW warming hypothesis.
The AGW biases within the AMS policy makers is so entrenched that it would be impossible for well known and established scientists (but AGW skeptics) such as Fred Singer, Pat Michaels, Bill Cotton, Roger Pielke, Sr., Roy Spencer, John Christie, Joe D’Aleo, Bob Balling, Jr., Craig Idso, Willie Soon, etc. to ever be able to receive an AMS award – irrespective of the uniqueness or brilliance of their research.
What Working Meteorologists Say. My interaction (over the years) with a broad segment of AMS members (that I have met as a result of my seasonal hurricane forecasting and other activities) who have spent a sizable portion of their careers down in the meteorological trenches of observations and forecasting, have indicated that a majority of them do not agree that humans are the primary cause of global warming. These working meteorologists are too experienced and too sophisticated to be hoodwinked by the lobby of global climate modelers and their associated propagandists. I suggest that the AMS conduct a survey of its members who are actually working with real time weather-climate data to see how many agree that humans have been the main cause of global warming and that there was justification for the AMS’s 2009 Rossby Research Medal (highest AMS award) going to James Hansen.
Global Environmental Problems. There is no question that global population increases and growing industrialization have caused many environmental problems associated with air and water pollution, industrial contamination, unwise land use, and hundreds of other human-induced environmental irritants. But all these human-induced environmental problems will not go away by a draconian effort to reduce CO2 emissions. CO2 is not a pollutant but a fertilizer. Humankind needs fossil-fuel energy to maintain its industrial lifestyle and to expand this lifestyle in order to be able to better handle these many other non-CO2 environmental problems. There appears to be a misconception among many people that by reducing CO2 we are dealing with our most pressing environmental problem. Not so.
It must be remembered that advanced industrial societies do more for the global environment than do poor societies. By greatly reducing CO2 emissions and paying a great deal more for our then needed renewable energy we will lower our nation’s standard of living and not be able to help relieve as many of our and the globe’s many environmental, political, and social problems.
Obtaining a Balanced View on AGW. To understand what is really occurring with regards to the AGW question one must now bypass the AMS, the mainstream media, and the mainline scientific journals. They have mostly been preconditioned to accept the AGW hypothesis and, in general, frown on anyone not agreeing that AGW is, next to nuclear war, our society’s most serious long range problem.
To obtain any kind of a balanced back-and-forth discussion on AGW one has to consult the many web blogs that are both advocates and skeptics of AGW. These blogs are the only source for real open debate on the validity of the AGW hypothesis. Here is where the real science of the AGW question is taking place. Over the last few years the weight of evidence, as presented in these many blog discussions, is beginning to swing against the AGW hypothesis. As the globe fails to warm as the GCMs have predicted the American public is gradually losing its belief in the prior claims of Gore, Hansen, and the other many AGW advocates.
Prediction. The AMS is going to be judged in future years as having foolishly sacrificed its sterling scientific reputation for political and financial expediency. I am sure that hundreds of our older deceased AMS members are rolling in their graves over what has become of their and our great society.

Global warming is a Leftist lie. It is not enough to debunk and marginalize the perpetrators of this fraud. There needs to be serious consequences including steep fines and lengthy jail time so that none of them ever again try to pull such a fraudulent scam.
John P. Reisman says:
No Tony, I gave you a link to the testimony from a scientist with some of the latest findings. In his testimony he pointed out that these are not models, but actual observations.
John,
The quote you provided is someone’s testimony that references a specific paper (Schlenker and Roberts 2009) that made the determination of a 7% diminution in crop yield. The quote I provided was taken from that paper. It clearly indicates that the 7% diminution was a modeling prediction. While it may be “based on observations”, it is not an actual observation.
In fact, what you are claiming was “observed” is something that would be physically impossible to observe – unless you’re telling me that they somehow were able to control for all the other variables so that the only difference was the single day at 104 vs 84. If that is, indeed, the case, I would be quite interested in learning of the mechanism for doing so.
John, sea water is nearly opaque to the far infrared spectrum, which penetrates depths measured in mm and is also the depth at which evaporation is the rule. There is no way this tiny amount of heating, most of which does not even stick around, can be responsible for the rise in OHC. It amazes me that you continue to argue that point.
Pamela Gray – the link you posted is nonsense AGWScienceFiction production, which discounts the thermal infrared we actually feel as heat from the Sun in its ‘energy budget’. Claiming, as in your link, that it is ‘Solar’, i.e. Visible and the two shortwave either side, which heat the Earth, and that the real heat energy we feel from the Sun has no part in this.
Visible, Light, is transmitted through water which is a transparent medium for it, it is not absorbed and doesn’t create heat. Thermal infrared actually downwelling from the Sun, is what actually heats the oceans and land of our planet. Thermal infrared converts to heat in water readily, just as it does in our bodies, it is then distributed through the water by convection.
If you find the wiki page on water absorption spectrum, you’ll see the Visible is practically non-existent, all the absorption is in the infrared.
‘Transmitted’ is the term used for the particular way the shorter, tiny, shortwave Light gets through water, it is not absorbed but rejected by the molecules of water from joining in and so pass through. In the atmosphere the molecules of oxygen and nitrogen scatter these tiny waves, giving us our blue sky.
Anyway, what is nonsense is the claim that thermal infrared, Heat cf Light, does not get to the surface of the Earth.
And nonsense that it’s the Visible that heats the Earth.
While the furious debate continues here about what an increase of ~1W/m^2 in backradiation supposedly due to risisng CO2 concentrations may or may not do, the variations in local insolation well in excess of 100W/m^2 due to ever-changing cloud cover are strangely neglected. Considered on a global basis, a variation of just a few percent in the effective albedo is far more significant to surface temperatures than variations in GHG concentrations.
It may come as a surprise to those accustomed thinking in terms of simplistic “radiative balances” that OLR and surface temperature are NEGATIVELY correlated in the tropics at decadal time scales. This is a consequence of cloud cover being not only the gatekeeper for insolation, but also a powerful inhibitor of night-time radiative loss.
That some of the ardent partisans of AGW doctrine pontificating here are unaware of the complexities of the climate system is perhaps understandable. But such ignorance on the part of AMS officers is inexcusable.

re. “Global warming is a Leftist lie. It is not enough to debunk and marginalize the perpetrators of this fraud. There needs to be serious consequences including steep fines and lengthy jail time so that none of them ever again try to pull such a fraudulent scam.”
This is a great example of someone that does not have enough integrity to post his full legal name and yet make outrageous accusations that are not substantiated.
The person that wrote this is a liberal.
‘given or provided in a generous and openhanded way’
or
‘given, used, or occurring in generous amounts’
He has, without substantiation generously made a claim without substantiation. And then he thinks that those that actually do science, which happens to be the most conservative organized endeavor in human history, should be put in jail.
This sort of liberalism that he/she displays should be shunned.

Pamela, I’m not an expert in this area. Can you give me one single cite from a reputable science source on your claim. Then I can check it out, see if it has merit, examine counter arguments, see if it survived peer response and get back to you and say base on on ??? whether you are more or less likely to be correct on the issue.
I’m beginning to get the feeling that you just don’t believe in using the scientific method and prefer your opinion.

re. “furious debate”
I don’t think I’ve ever seen a furious debate at a scientific conference? What are you referring to? The debate in the public and media?
re. “cloud cover are strangely neglected”
Can you actually name one single working climate scientist that ignore cloud cover?
Ingoing and outgoing radiation is studied intensely and clouds are a big part of the big picture in consideration of radiation balance.
So, what makes you think science or scientists are not studying clouds?

re. “Global warming is a Leftist lie.”
Technically, without global warming the average temperature of Earth would be just below zero degrees fahrenheit and you would be a frozen block of flesh.
Can you prove that you are frozen solid?
Your risible comment is highlighted by the idiocy uttered by Tyndall. Without the “aqueous vapour” in the air, what, pray tell, would make the “frost”? Congealed CO2?
Pathetic.
Technically, almost entirely due to H2O. Can you prove that your brains are not frozen solid? The only thing of significance that would happen from eliminating CO2 from the air is the near sterilization of the planet, as plant life ended, along with the parasitic fauna, leaving only a few exotic extremophile bacteria.
It is literally vital that we maintain and increase the levels of CO2 in the atmosphere, forever.
Brian Hall says: June 22, 2011 at 3:48 am
re. “Technically, almost entirely due to H2O.”
Really? Can you show me one single article from a reputable science source that proves your point?
See, the problem is, that if you remove the CO2, it’s cold enough for more H20 to freeze, which also reduces the positive feedback mechanisms, which leads to an icebound state.

re. “It is literally vital that we maintain and increase the levels of CO2 in the atmosphere, forever.”
Really? So, your okay with a atmosphere like that of the Permian/Triassic boundary
http://science.nasa.gov/science-news/science-at-nasa/2002/28jan_extinction/
Hmm… flood basalt eruptions injecting 1.5 million cubic kilometers of volcanic ejecta, massive CO2 increase, and the icing on the cake of a 6 to 12 km asteroid to flash burn the CO2 sink just for an extra boost causing a climate change temperature increase to about 7 to 8 degrees C hotter than today.
That actually sounds like your kinda climate?
Where are you going to grow your crops, in your cave?
Of course the Sun heats both land and water. I am not referring to that source of ocean heating. It is the re-emitted far infrared LW radiation (the stuff that both water vapor and CO2 re-emits) that does not penetrate but a few mm, just barely getting past the surface tension of sea water, to be dissipated back into the atmosphere through evaporation. However, the AGW tome says that it is this incredibly weak heat source that is causing the oceans to heat beyond the natural Solar source. But there is no mechanism and no maths that has shown this to be the probable cause.
Pamela Gray says: June 22, 2011 at 10:26 am
Pamela, Either you don’t have and reputable science source or citation for your assertion, or you have one and don’t want to share it. Which is it?
John Reisman,
Maybe Pamela Gray is just ignoring your constant pestering. You want citations? Here are some from the paper she linked to upthread, and which you evidently did not read:
Pam has been around here for a long time, and from where I sit she is more knowledgeable than you.
John P. Reisman says:

“So, what makes you think science or scientists are not studying clouds?”
I never said that. What I observe is that in public debates the HIGHLY DOMINANT effect of clouds, about which climate scientists know very little beyond the cartoonish schematics that you reference, is not acknowledged by them. And you certainly show no sign of comprehending that the effects of varying CO2 concentrations are orders of magnitude less important in setting the surface temperatures than those due to cloud-induced variations in insolation.
I have no interest in pursuing any discussion with someone whose basic M.O. is dismissal of anything that he hasn’t read about in the pal-reviewed literature. That’s not how true scientists become acquainted with physical reality. Sayonara!
Reisman, the plants grew just fine with that elevated CO2 and temperature. So would crops, though we might end up with different (probably more productive) cultivars.
And, as usual, your attribution of the temperature levels to CO2 is textbook “begging the question”.

and
“Pam has been around here for a long time, and from where I sit she is more knowledgeable than you.”
You’re right I did not read them all. And I’d bet neither have you. But by your sarcasm you infer you have. So, I will assume you have read them all, and that Pamela has read them all.
And since you are both more knowledgable than I and have read all those papers, please tell me which of them answers my question and backs up what pamela is saying namely her assertion:
Then, if said assertion exists in the peer reviewed literature we need to figure out if it survived peer response, and in what context does the assertion apply with regard to OHC?
I anxiously await your informed reply with the proper citation, as opposed to a laundry list of cites from which it is likely that neither you nor she has actually read all.
Can either you or Pamela name the paper that supports Pamela’s claim, from a reputable science source? That does not mean throw a cite list into a thread. I can do that too, but as you will note above, I don’t do that. I am courteous enough to send you to a single source to support each scientific point.
You see, it doesn’t matter how long Pam has been around in this blog. And it doesn’t matter if you think she is more knowledgable than I. Science does not care about my opinion. Science does not care about Pam/s opinion. And science does not care about your opinion.

re. “I never said that.”
regarding what I said “So, what makes you think science or scientists are not studying clouds?”
about what she said “the variations in local insolation well in excess of 100W/m^2 due to ever-changing cloud cover are strangely neglected.”
re. “What I observe is that in public debates the HIGHLY DOMINANT effect of clouds, about which climate scientists know very little beyond the cartoonish schematics that you reference, is not acknowledged by them.”
and
“And you certainly show no sign of comprehending that the effects of varying CO2 concentrations are orders of magnitude less important in setting the surface temperatures than those due to cloud-induced variations in insolation.”
Actually I fully recognize the importance of clouds and the ‘enormous effect they have on our climate. Reflected solar radiation is on the order of 700 W/m2, which is orders of magnitude larger than GHG imbalance changes. What you still fail to realize is that even something that seems small in your mind, can have a large impact on the earth climate.
Again, science does not care what you think. It only cares about evidence. Tipping the average forcing 0.1 W/m2 in the Maunder Minimum caused agricultural failures in Europe. Now we have tipped it positive 1.66 W/m2 on the mean. And you think that is a little effect. Based on the evidence of the Maunder Minimum, you are wrong. I little change can have a large impact.
re. “That’s not how true scientists become acquainted with physical reality.”
I work with true scientists a lot throughout my career. And lately I’ve had the great pleasure of working with many climate scientists. Your assertion regarding the “pal-reviewed literature” indicates strongly that you really don’t know how the scientific method works. So your pretty much talking out of your hat.

My point was this this is irrelevant. You posted a link to what you said was an article “that most here will be able to understand. The author is well-versed in ocean heating”
I’m calling it junk AGWScience, the author knows zilch about how the oceans are heated since he follows AGWScience by saying Solar heats the Earth and Thermal Infrared is what is radiated back up from the heated Earth.
Whatever you think “Solar” means, in AGWScienceFiction is doesn’t include downwelling Thermal Infrared.
“Solar” in the AGWScience energy budget is only the shortwave Visible and UV&Near Ir either side. None of these is capable of converting to heat land and oceans, as claimed in the KT97 for example.

re. “plants grew just fine with that elevated CO2 and temperature”
and
re. “So would crops, though we might end up with different (probably more productive) cultivars”
An issue here that is rather important is the speed of change. Other than asteroid impacts, most events had prolonged ramp times of various time scales. Slower changes in relation to structure of biologic systems regulates life capacity ans survivability potentials. Slower change speed allow life to adjust, rapid changes do not. Thus more extinctions occur when change is relatively faster.
We exist in a world much different that the Permian peak where the CO2 levels were much higher of course. But at that time most life on earth ended, and for various reasons, likely all combined with various degrees of influence and impact in various time scales.
The Permian boundary is marked by a distinct phenomenon followed by millions of years of recovery. As described by Dr. Roger Smith, speaking about the End-P event in a BBC interview:
“This is the dead zone. this zone represents what it was like here after the mass extinction. We have never found anything that represents life in this zone. This is what we would call barren. There is no evidence of plant life, there are no evidence of soils, and especially there is no evidence of animals. This is completely dead.”
The Eocene optimum also had higher CO2 levels, and is also associated with an extinction event.
So basically, your notion of
“It is literally vital that we maintain and increase the levels of CO2 in the atmosphere, forever.”
probably, or is very likely, unsound. For example. Venus has very high levels of CO2 (96.5% of the atmosphere is CO2) and the surface temperature is 464ºC (867.2º F)
http://nssdc.gsfc.nasa.gov/planetary/factsheet/venusfact.html
So how can you logically, reasonably or sensibly conclude that ‘increasing the levels of CO2 in the atmosphere, forever’ is a good idea?
Context is key.
Dr. G you are a jewell in the midst of scientific heresy, but sadly in these times of spin and slur; honest, smart voices are drowned by politically correst, selfish, and really dumb folks with the ink, the airwaves, and the microphones. Keep in good health and great spirits.
