#ExxonKnew ?? meh… #JohnsonKnew The 1965 Presidential Science Report on Carbon Dioxide and Pollution

Gosh, president Johnson knew, and did nothing? Regular readers of this website have been following the ridiculous #ExxonKnew campaign put together by Al Gore and a smattering of activist attorney generals, aided by 350.org nutty activist “Weepy” Bill McKibben. It isn’t going well, as there has been setback after setback, with some AG’s being ordered to appear in court, and refusing to do so.

Thanks to a tweet by Associated Press activist journalist Seth Borensten, I became aware of this November 1965 report from the President’s Science Advisory Committee titled: Restoring the Quality of Our Environment  Link: PSAC-1965-Restoring the Quality of Our Environment (PDF)

Borenstein makes this claim:

From Seth’s point of view, it looks like an “open and shut case”, and no further investigation is needed. However, one commenter was quick to remind Seth that “global warming” was reported well before 1965:

Indeed. But Al Gore, the activist AG’s, and the McKibbenites tried to make a manufactured big deal out of the fact that Exxon scientists had internal reports on climate change back in 1977, and “did nothing” with them, especially not advising shareholders. This ludicrous claim has caused much climatic caterwauling such as we see in the former jewel of science magazines, Scientific American: Exxon Knew about Climate Change almost 40 years ago

Exxon was aware of climate change, as early as 1977, 11 years before it became a public issue, according to a recent investigation from InsideClimate News. This knowledge did not prevent the company (now ExxonMobil and the world’s largest oil and gas company) from spending decades refusing to publicly acknowledge climate change and even promoting climate misinformation—an approach many have likened to the lies spread by the tobacco industry regarding the health risks of smoking.

Gosh, that’s 12 years after President Lyndon Johnson (D-Texas), knew, and did nothing. Here’s the money quote from that 1965 report:

SciAm foolishly thinks that the “ground zero date” for public awareness of CO2 and climate was June 1988, when James Hansen went before congress with his famously modeled 3 scenarios, and told the world we have a serious problem.

What most people don’t know, is that Hansen’s science was so…so…er, “robust” at the time, that he and his sponsor, Senator Timothy Wirth (D-Colorado), had to do some stagecraft by choosing a hot day for testimony (thanks to Weather Bureau forecast), and opening the windows, which negated the air conditioning. I kid you not, they needed the room “hot” to convince legislators to throw money at them.

This transcript excerpt is from PBS series Frontline which aired a special in April 2007.

TIMOTHY WIRTH: We called the Weather Bureau and found out what historically was the hottest day of the summer. Well, it was June 6th or June 9th or whatever it was. So we scheduled the hearing that day, and bingo, it was the hottest day on record in Washington, or close to it.

DEBORAH AMOS: [on camera] Did you also alter the temperature in the hearing room that day?

TIMOTHY WIRTH: What we did is that we went in the night before and opened all the windows, I will admit, right, so that the air conditioning wasn’t working inside the room. And so when the- when the hearing occurred, there was not only bliss, which is television cameras and double figures, but it was really hot.[Shot of witnesses at hearing]

Watch the Frontline video

Science and stagecraft, for the cameras, for the funding, for the win!

So, to recap…a Democratic President, Lyndon Johnson, knew in November 1965, well before it “became a public issue” in June 1988, that  “increased CO2 content could be deleterious from the point of human beings” and did nothing.

Gosh.

Surely Johnson can now be labeled a “denier”. I’m sure Al Gore, the activist AG’s and the McKibbenites will jump right on that, and work hard to smear the name of President Johnson, and sue his estate for his “crime against humanity” of knowing, and doing nothing.

Yeah, that’s the ticket.

Mr. Watts,
You were entirely correct the first time and should not have crossed out the word “activist” when describing Seth Borenstein.

He certainly is not an even-handed reporter or journalist when it comes to climate-related topics.

Johnson and his scientist advisors did not “know.” They CONJECTURED about human CO2 emissions. (See above-quoted “Conclusions and Findings”)

Thus, the above article is good, but missing a key piece of information:

CO2 UP. WARMING NOT.

That is, the MAIN point needs to be, not whether Johnson or Smith or Jones or Pinkerton believed human CO2 might cause significant shifts in the climate zones of the earth,

the MAIN point is:

their conjecture means NOTHING.

NOTHING.

I find it interesting that the first specualtive consequenc of increased co2 on mankind mentioned in the conclusion is “deleterious”. I wonder if the report states as a possibility any positive consequence. If not, it would show you that, as early as the 60’s, government scientists and administrators were pushing the negative interpretive bias for CO2, totally ignoring the posible benefits to mankind of added CO2. Something that continues to this day 60 years on…smh.

“We called the Weather Bureau and found out what historically was the hottest day of the summer. Well, it was June 6th or June 9th or whatever it was. So we scheduled the hearing that day, and bingo, it was the hottest day on record in Washington, or close to it.”

The hearings were on the 23rd of June, and I’d be surprised if the hottest day if the year isn’t normally in July.

AD 1965 was during the postwar global cooling, 1945-77, which occurred despite rising CO2. Some scientists “knew” that more CO2 should slightly warm the planet since c. 1900, but it hadn’t done so.

The range in the report of 1.1 to 7.0 degrees F per doubling is ludicrous. It assumes feedback effects from a little bit net negative to wildly positive.

The voice of a scientist’s scientist:

Sent: Friday, 08 October 2010 17:19 Hal Lewis
From: Hal Lewis, University of California, Santa Barbara
To: Curtis G. Callan, Jr., Princeton University, President of the American Physical Society

6 October 2010

Dear Curt:

When I first joined the American Physical Society sixty-seven years ago it was much smaller, much gentler, and as yet uncorrupted by the money flood (a threat against which Dwight Eisenhower warned a half-century ago). Indeed, the choice of physics as a profession was then a guarantor of a life of poverty and abstinence—it was World War II that changed all that. The prospect of worldly gain drove few physicists. As recently as thirty-five years ago, when I chaired the first APS study of a contentious social/scientific issue, The Reactor Safety Study, though there were zealots aplenty on the outside there was no hint of inordinate pressure on us as physicists. We were therefore able to produce what I believe was and is an honest appraisal of the situation at that time. We were further enabled by the presence of an oversight committee consisting of Pief Panofsky, Vicki Weisskopf, and Hans Bethe, all towering physicists beyond reproach. I was proud of what we did in a charged atmosphere. In the end the oversight committee, in its report to the APS President, noted the complete independence in which we did the job, and predicted that the report would be attacked from both sides. What greater tribute could there be?

How different it is now. The giants no longer walk the earth, and the money flood has become the raison d’être of much physics research, the vital sustenance of much more, and it provides the support for untold numbers of professional jobs. For reasons that will soon become clear my former pride at being an APS Fellow all these years has been turned into shame, and I am forced, with no pleasure at all, to offer you my resignation from the Society.

It is of course, the global warming sc@m, with the (literally) trillions of dollars driving it, that has corrupted so many scientists, and has carried APS before it like a rogue wave. It is the greatest and most successful pseudoscientific fr@ud I have seen in my long life as a physicist. Anyone who has the faintest doubt that this is so should force himself to read the ClimateGate documents, which lay it bare. (Montford’s book organizes the facts very well.) I don’t believe that any real physicist, nay scientist, can read that stuff without revulsion. I would almost make that revulsion a definition of the word scientist.

So what has the APS, as an organization, done in the face of this challenge? It has accepted the corruption as the norm, and gone along with it. For example:

1. About a year ago a few of us sent an e-mail on the subject to a fraction of the membership. APS ignored the issues, but the then President immediately launched a hostile investigation of where we got the e-mail addresses. In its better days, APS used to encourage discussion of important issues, and indeed the Constitution cites that as its principal purpose. No more. Everything that has been done in the last year has been designed to silence debate

2. The appallingly tendentious APS statement on Climate Change was apparently written in a hurry by a few people over lunch, and is certainly not representative of the talents of APS members as I have long known them. So a few of us petitioned the Council to reconsider it. One of the outstanding marks of (in)distinction in the Statement was the poison word incontrovertible, which describes few items in physics, certainly not this one. In response APS appointed a secret committee that never met, never troubled to speak to any skeptics, yet endorsed the Statement in its entirety. (They did admit that the tone was a bit strong, but amazingly kept the poison word incontrovertible to describe the evidence, a position supported by no one.) In the end, the Council kept the original statement, word for word, but approved a far longer “explanatory” screed, admitting that there were uncertainties, but brushing them aside to give blanket approval to the original. The original Statement, which still stands as the APS position, also contains what I consider pompous and asinine advice to all world governments, as if the APS were master of the universe. It is not, and I am embarrassed that our leaders seem to think it is. This is not fun and games, these are serious matters involving vast fractions of our national substance, and the reputation of the Society as a scientific society is at stake.

3. In the interim the ClimateGate scandal broke into the news, and the machinations of the principal alarmists were revealed to the world. It was a fr@ud on a scale I have never seen, and I lack the words to describe its enormity. Effect on the APS position: none. None at all. This is not science; other forces are at work.

4. So a few of us tried to bring science into the act (that is, after all, the alleged and historic purpose of APS), and collected the necessary 200+ signatures to bring to the Council a proposal for a Topical Group on Climate Science, thinking that open discussion of the scientific issues, in the best tradition of physics, would be beneficial to all, and also a contribution to the nation. I might note that it was not easy to collect the signatures, since you denied us the use of the APS membership list. We conformed in every way with the requirements of the APS Constitution, and described in great detail what we had in mind—simply to bring the subject into the open.

5. To our amazement, Constitution be damned, you declined to accept our petition, but instead used your own control of the mailing list to run a poll on the members’ interest in a TG on Climate and the Environment. You did ask the members if they would sign a petition to form a TG on your yet-to-be-defined subject, but provided no petition, and got lots of affirmative responses. (If you had asked about sex you would have gotten more expressions of interest.) There was of course no such petition or proposal, and you have now dropped the Environment part, so the whole matter is moot. (Any lawyer will tell you that you cannot collect signatures on a vague petition, and then fill in whatever you like.) The entire purpose of this exercise was to avoid your constitutional responsibility to take our petition to the Council.

6. As of now you have formed still another secret and stacked committee to organize your own TG, simply ignoring our lawful petition.

APS management has gamed the problem from the beginning, to suppress serious conversation about the merits of the climate change claims. Do you wonder that I have lost confidence in the organization?

I do feel the need to add one note, and this is conjecture, since it is always risky to discuss other people’s motives. This scheming at APS HQ is so bizarre that there cannot be a simple explanation for it. Some have held that the physicists of today are not as smart as they used to be, but I don’t think that is an issue. I think it is the money, exactly what Eisenhower warned about a half-century ago. There are indeed trillions of dollars involved, to say nothing of the fame and glory (and frequent trips to exotic islands) that go with being a member of the club. Your own Physics Department (of which you are chairman) would lose millions a year if the global warming bubble burst. When Penn State absolved Mike M@nn of wrongdoing, and the University of East Anglia did the same for Ph!l Jones, they cannot have been unaware of the financial penalty for doing otherwise. As the old saying goes, you don’t have to be a weatherman to know which way the wind is blowing. Since I am no philosopher, I’m not going to explore at just which point enlightened self-interest crosses the line into corruption, but a careful reading of the ClimateGate releases makes it clear that this is not an academic question.

I want no part of it, so please accept my resignation. APS no longer represents me, but I hope we are still friends.

Hal

I am completely dumbfounded at the claim that public knowledge of climate change (this time round, concern over the warming) only became known in the late 1980’s. This is manifestly untrue.

There had been expeditions to the melting arctic amidst much public interest (Royal Society 1818) Numerous Conferences, Government meetings (1947 and earlier) and numerous newspaper reports from the 1700’s onwards with a particular flurry in the 1920’s onwards. At that time Bob Bartlett undertook numerous expeditions to the melting arctic which was filmed for Pathe newsreel which were seen by millions of our cinema going forefathers as news inserts in the main film offering.

The warming world was a ‘hot’ issue and in various of my articles I cite many hundreds of papers, newspaper clippings books etc that reference it.

Here is a short summary of the long standing interest in climate change which reached a peak in the early 1970’s cooling (following the concerns about warming from 1920) and was immediately followed by concerns of warming again. In that context the global cooling scare can be seen as a short term interruption in the centuries long (intermittent) warming.

—– —- —-
From my article ‘the long slow thaw.’

Reginald Jeffery observed in his book ‘Was it Wet or was it fine,’ “By 1708 the middle aged would say where are our old winters?”

This query was being echoed on the other side of the Atlantic around the same time as the records of the Hudson Bay Company demonstrate that climate change was not restricted to Europe.

“Over the fifteen years between 1720 and 1735, the first snowfall of the year moved from the first week of September to the last…”

Thomas Jefferson -third President of the United States- kept extensive weather records and referring to the period around the 1770’s remarked;

““A change in our climate however is taking place very sensibly. Both heats and colds are become much more moderate within the memory even of the middle-aged. Snows are less frequent and less deep. They do not often lie, below the mountains, more than one, two, or three days, and very rarely a week. They are remembered to have been formerly frequent, deep, and of long continuance. The elderly inform me the earth used to be covered with snow about three months in every year. The rivers, which then seldom failed to freeze over in the course of the winter, scarcely ever do so now. (54)

A few decades later Noah Webster, 1758-1843 (founder- Webster’s dictionary) commented;

“The temperature of the winter season, in northern latitudes, has suffered a material change, and become warmer in modern, than it was in ancient times. … Indeed I know not whether any person, in this age, has ever questioned the fact.”

Towards the end of the 19th Century a correspondent in the Canadian Horticulturist monthly of 1880 (page 7) remarked;

“I do not know whether or not the climate of Ontario is really becoming permanently milder than formerly, but I do know that for the past 18 years or 20 years we have not experienced the same degree of cold as the seven years preceding.”

Writing in 1931 after several decades of compiling his book ‘Was it wet or was it Fine’ Reginald Jeffery remarked;

“I have been asked so often during the period that I have been doing this work this question, well after all this grubbing into the wealth of the past, do you think that our climate is changing or has changed? Where are the old snow storms? We never quite know where we are with regards to weather.”

Whilst around the same time a farmer from Buchan in Scotland wrote to his local newspaper;

“1934 has opened true to the modern tradition of open, snowless winters. The long ago winters are no precedent for our modern samples. During the last decade, during several Januarys the lark has heralded spring up in the lift from the middle to the end of the month. Not full fledged songs but preliminary bars in an effort to adapt to our climatic change.”

It then goes on to say;

“It is unwise to assume that the modern winters have displaced the old indefinitely” and also; “Our modern winters have induced an altered agricultural regime”

—– —— —–

If the public interest in climate change and global warming was not being discussed until the late 1980’s then it appears all these references were cleverly hidden in plain view.

Let me see: damage Lyndon Johnson’s reputation any more than he did all by himself, or has been done over time by what he left behind? No, that’s impossible. He made a mess out of his administration without any help from anyone else.

A 1967 memo https://history.state.gov/historicaldocuments/frus1964-68v34/d228 shows that his administration was active in the mess that was already starting to raise its head in the Middle East.

That was in the middle of the Vietnam War. No, LBJ did plenty of damage to his reputation on his own. This bit of hogwash cooked up out of dust bunnies is just that – hogwash.

As evidenced by his 1977 film, Close Encounters of the Third Kind, Spielberg knew that space aliens were here, and just biding their time until their Big Invasion coming soon. George Lucas will also be named in the suit, as well as others, all of whom knew about space aliens, yet not only profited from it, but also pretended it was just fiction, for our amusement only.

Funny to see you refer to SciAm as “the former jewel of science magazines.” I see my recollection of events meshes well with what you report here. I remember that in the late 80s (and my memory also says “1988”) SciAm ran what was (I believe) its first article on global warming (I wonder if it was written by Hansen). I remember reading it and calling “BS”. I thought the model probably lacked certain feedbacks (like heating-increased cloud cover-increased albedo) and later proved to be correct. I had, at the time, subscribed to SciAm for over a decade. At this same time (late 80s) I had been perceiving a noticeable leftist slant in its stories and allowed my subscription to lapse shortly thereafter. Now I only buy an occasional special issue on safe (from politicization) topics like cosmology.

In the year of my Ph.D., Austin, the one TV station controlled by LBJ, the 1965 government science report linked showed heavy reliance on administrators (1 from UT) and government officials. One W. J. Youden has only an address, in Washington. I only know something of the scientific credentials of two on in the list, Ruth Patrick and Lionel Walford, probably good choices. Of the different section chairmen, nearly all are apparently non-administrators from universities.

Of course, Roger Revelle was the head of the carbon dioxide section. Compared to government reports nowadays this seems to be a great piece of science, showing both pros and cons and maybes. As to pH they only mentioned freshwater and “This will have no significant effect on most plants,” and they mentioned the fertilizing effect of carbon dioxide. Back in those days we knew the difference between acids and bases and we still had lots of real pollution in LBJ land to deal with. They also knew cod populations followed temperature, something fisheries scientists lost in their computers and are having to rediscover. Nevertheless, there were some with solutions looking for problems.

November 5, 2017 2:38 pm

This has been beat to death but here it goes again:

What is it that they knew decades ago, which they did not share with the world that they should be held accountable for?

1. Booming biosphere and greening planet? No
2. Record crop yields and world food production? No
3. Best weather/climate in at least 1,000 years for life……since the Medieval Warm Period that was this warm? No
4. Decreasing strong/violent tornadoes with the decreasing meridional temp. gradient from warming the higher latitudes? No
5. No trend in hurricanes/typhoons? No
6. No acceleration in sea level increase? No

7. Increase in atmospheric moisture of around 2% since that time frame and corresponding slight increase in extreme rain events. This happened
8. Melting Arctic sea ice. This happened
9. Slight increase in heat waves in some regions. This happened
10. Global climate model projections of temperature that have been too warm and no skill at predicting region weather. This happened and are the entire basis to build the case for catastrophic human caused climate change on.

Items 1-9 are based on authentic science. Item #10 is based on a political agenda and is also the one that they are actually being held accountable for. If they had sounded the false alarms sooner, the hijacking of climate science could have commenced much earlier and the politics based on junk science might well have(given a decade head start) been successful at committing the world to non scientifically based, transfer of wealth agreements, like the Climate Accord…….before the observations and data caught up and busted the exaggerated versions of the busted speculative theories……..like they are doing right now.

Seth Boringstone again lives up to his name and submerges us in witless prattle. Svante Arrhenius was a Nobel-Prize winning Swedish scientist who knew that a warmer world would be a better world. Nothing that we see now, shows that Arrhenius was wrong, but Boringstone is.

That 1965 document was indeed a “consensus” report from many of the leading scientits of the day. And it warmed in dramatic terms about the rise of CO2. Yet this is the time when some are telling us that they were preoccupied with a cooling scare?

November 5, 2017 2:59 pm

Back in the 1960’s, 1 car produced as much real pollution as around 25 cars today. In the 1960’s we knew what real pollution was and thanks to the catalytic convertor, the most ingenious/effective pollution fighting device in history…..we helped reduce a massive source of it.

Funny thing about pollution since then. Catalytic convertors, create a bunch of CO2. In the 1960’s this was still considered a beneficial, non toxic, colorless, odorless, benign gas which played its most important role in the law of photosynthesis, enhancing plant growth.

Now, it’s being defined as carbon pollution and the increase in CO2 is the leading cause for model simulations of our atmosphere going out 100 years that project human caused catastrophic climate change.

3 way catalytic convertor:

1. Reduction of nitrogen oxides to nitrogen and oxygen: 2 NOx → x O2 + N2
2. Oxidation of carbon monoxide to carbon dioxide: 2 CO + O2 → 2 CO2
3. Oxidation of unburnt hydrocarbons (HC) to carbon dioxide and water: CxH2x+2 + [(3x+1)/2] O2 → x CO2 + (x+1) H2O.

Who could have guessed back then that we were just converting air pollution with well known and observed adverse health effects on humans into an even worse form of pollution that remains in the atmosphere for a century and is a much worse threat to life on this planet………..based on programmed models that simulate the atmosphere for a century…… via interpretations by the main gate keepers of our climate science.

The ExxonKnew case I find so confounding every time I look at it. Here are some interesting points:

— The scientific assessment reports in the DoE carbon dioxide program in the early 1980s was that there was no empirical evidences of the proposed effect, and that first detection is not likely until the new century. They therefore saw their work as preparing for how best to establish first detection.

— The first international assessment report “Scope 29″ in 1985 did not even suggest a date when first detection might be achieved.

— The first IPCC report said that detection is not likely for decades.

— In the second IPCC report, first it said in response to the question of when the empirical science might arrive” ‘we don’t know’. When this was removed in a late revision, the conclusion was still only ‘points towards’ a discernible human influence. So, even in 1996 there was no conclusive evidence according to scientific assessments. There were lots of papers at the time expressing doubt about the empirical evidence including the paper by Santer that was the main basis for the IPCC claim — when it was eventually published.

— If we go to individual scientists claiming detection, we have George Plass in the 1953 and 1956, and before that Callendar in 1938. So #PlassKnew and #CallendarKnew. Its only that they were heavily criticized by the experts, including notably Roger Revelle.

So ‘Exxon knew’ can only be about contentious claims of Callendar and Plass….or conjecture (as Janice Moore says above). And the conjecture goes right back to Svante Arrhenius etc in the late 19th century that was persuasively critiqued by Ångström in 1900.

Back to 1965. This blog post above quotes a subsection to the Appendix to the report that was given to the new president Johnson early in 1965. The author, Revelle, speculates about CO2 warming melting of the Antarctic ice cap at a rate of 4 feet per decade and so after 1000 years a rise of 400 feet. That is the highest speculated AGW sea level rise I have seen.

— Not only did Johnson know but less than 3 weeks after his inauguration (8 Feb 65), in a special message to Congress on pollution, President Johnson commented:

Large-scale pollution of air and waterways is no respecter of political boundaries, and its effects extend far beyond those who cause it. Air pollution is no longer confined to isolated places. This generation has altered the composition of the atmosphere on a global scale through radioactive materials and a steady increase in carbon dioxide from the burning of fossil fuels.

see here: http://www.lbjlib.utexas.edu/johnson/archives.hom/speeches.hom/650208.asp

— And #ExxonKnew folks know #JohnsonKnew. See Naomi Oreskes here:
See here: http://www.washingtonpost.com/wp-dyn/content/article/2007/01/31/AR2007013101808.html

So, there is nothing new here for the #ExxonKnew. And this is why I am so perplexed. What exactly is the claim about Exxon? I just don’t understand how these folks are seeing the history.
