May 29, 1969 – “A Chemist Thinks about the Future” #Keeling #KeelingCurve

On this day, May 29, 1969, Dave Keeling gave an inaugural lecture. Its title –

“A Chemist Thinks About the Future”

I could quote for hours.

“Nevertheless, no atmospheric scientist doubts that a sufficiently large change in atmospheric carbon dioxide would change the climate: we need only compare our atmosphere with the very hot carbon dioxide-laden atmosphere of Venus to guess the consequences of unrestricted carbon dioxide increase. The question is: how much before it matters? “

The whole thing is worth a read- the citation is

Charles D. Keeling PhD (1970) A Chemist Thinks About the Future, Archives of Environmental Health: An International Journal, 20:6, 764-777, DOI: 10.1080/00039896.1970.10665656
To link to this article: http://dx.doi.org/10.1080/00039896.1970.10665656

From the end (spoilers!) Keeling writes this

“Today we hold widely divergent views concerning possible peril. Have you noticed that practically all master plans do not project beyond the year 2000 AD? Our college students, however, today expect or hope to live beyond that date, and I predict that they will be the first generation to feel such strong concern for man’s future that they will discover means of effective action. This action may be less pleasant and rational than the corrective measures that we promote today, but 30 years from now, if present trends are a sign, mankind’s world will be in greater immediate danger than it is today. Immediate corrective measures, if such exist, will be closer at hand. If the human race survives into the 21st century with the vast population increase that now seems inevitable, the people living then, in addition to their other troubles, may face the threat of climatic change brought about by an uncontrolled increase in atmospheric carbon dioxide from fossil fuels.”

(Keeling, 1970: 776-7)


Btw, have you noticed that practically all of today’s master plans do not project beyond the year 2050 AD?

This graphic is darkly amusing –

We’re now at 420ppm, not 320. So it goes.

Why this matters. 

It doesn’t, particularly, any more than any blog post on this site does. But it keeps me off the streets, so there’s that.

What happened next?

Keeling kept on counting.

The thing he kept counting kept climbing.

And here we are.

[but of course, beware the fetishization of carbon dioxide!]

May 28, 1956 – Time Magazine reports on “One Big Greenhouse”

On this day, 28 May 1956, Time magazine ran an article with the following text:

“Since the start of the industrial revolution, mankind has been burning fossil fuel (coal, oil, etc.) and adding its carbon to the atmosphere as carbon dioxide. In 50 years or so this process, says Director Roger Revelle of the Scripps Institution of Oceanography, may have a violent effect on the earth’s climate… “Dr. Revelle has not reached the stage of warning against this catastrophe, but he and other geophysicists intend to keep watching and recording. During the International Geophysical Year (1957-58), teams of scientists will take inventory of the earth’s CO2 and observe how it shifts between air and sea. They will try to find out whether the CO2 blanket has been growing thicker, and what the effect has been. When all their data have been studied, they may be able to predict whether man’s factory chimneys and auto exhausts will eventually cause salt water to flow in the streets of New York and London.” –

“One Big Greenhouse,” Time magazine, May 28, 1956.

Why this matters

It’s nice context for the “puzzle” Roger Revelle asked Charles Keeling to look at.

What happened next?

Revelle hired Keeling (check out Joshua Wienberg’s “The next 100 years” for more about this.

The Keeling Curve was born.

“We” ignored it.

The end.

May 25, 1953 – “I read about them in Time Magazine” (Gilbert Plass’s greenhouse warning

On this day, May 1953, Time Magazine reported on Gilbert Plass’ presentation at the American Geophysical Union

.Careful readers of this site will know that a Western Australian newspaper had already covered this –

May 5, 1953 – Western Australian newspaper carries “climate and carbon dioxide” article

Why this matters

The idea of a greenhouse world was well understood by the mid-1950s (albeit a smaller concern than – say – thermonuclear war)

See May 28th for another (early) timely Time piece.

May 24, 2007 – James Hansen ponders whether scientists can be too cautious and quiet (or, indeed “reticent”)

On this day, May 24 2007 James Hansen’s paper  “Scientific Reticence and Sea Level Rise” was published.

Hansen made the basic point that – ah, hell, here’s the abstract –

I suggest that a ‘scientific reticence’ is inhibiting the communication of a threat of a potentially large sea level rise. Delay is dangerous because of system inertias that could create a situation with future sea level changes out of our control. I argue for calling together a panel of scientific leaders to hear evidence and issue a prompt plain-written report on current understanding of the sea level change issue.

Why this matters. 

Despite what the lunatic climate deniers will tell you, scientists are generally very very cautious, unwilling to extrapolate beyond their datasets. They are human, make mistakes, come to false conclusions, sure.  But on the whole “science” is pretty damned hot.  And it if there is a bias, it is towards reticence – that’s before we even talk about the chilling effect of smear campaigns etc etc.

What happened next?

Hansen has kept on trucking. A mensch [on second thought, does someone have a better word that isn’t so gendered?]

May 19, 1937 – Guy Callendar’s carbon dioxide warning lands on someone’s desk

On this day, 85 years ago, a paper with the catchy title “THE ARTIFICIAL PRODUCTION OF CARBON DIOXIDE AND ITS INFLUENCE ON TEMPERATURE” landed on the desk of the editor of the Quarterly Journal of the Royal Meteorological Journal. It was by one Guy Callendar, who was not even a “proper” scientist, “merely” a careful and diligent collector of data…

Historian James Fleming has written about Callendar – see here.

What happened next?

The paper was accepted. Callendar presented his findings, to general indifference (people who, 40 years later were serious players in the emerging climate consensus were present in the room, e.g. Kenneth Hare).

Callendar’s work caught the attention of scientists such as Hermann Flohn and Gilbert Plass, and was well known to the Roger Revelles and Hans Seuss’s of the world.

Why this matters

At this point, I should make clear what I am NOT saying.

I do not think anyone in 1938, hearing Callendar, should have dropped everything and raised immediate alarm. In 1938 the species – or at least the British Establishment – had other things on its mind.

I don’t even particularly “blame” people much later. I think it is really only in the late 1970s that the precautionary principle properly kicks in, and that the evidence and scientific consensus is strong enough to warrant serious action. This action did not come. Thanks Ronald. Thanks Margaret. Thanks Malcolm.

[The question of whether that consensus could have been accelerated if proper action was taken at the end of the 60s? I am agnostic. It is also not the most useful question to ask, I guess.]

So, we should know the history, but not use it to blame people for things that they could not by any reasonable measure have done that much about.

May 18, 1976 – US congress begins hearings on #climate

“On May 18, 1976, the House Subcommittee on the Environment and the Atmosphere (of the Committee on Science and Technology) met under the chairmanship of Congressman George Brown (D., Calif.) for the first of 6 days of hearings on the subject of climate and related research”(Hecht, 1981).

The early-mid 70s had seen a series of droughts, crop failures, cold winters and generally weird weather. Public and policymaker interest/concern were all high. This quote below, from an excellent 2014 paper called “The Dilemma of Reticence” (Henderson, 2014) gives useful info.

“Given Schneider’s rise as one of the most visible climatologists in the United States, Rep. George Brown, Jr. (D-CA) asked him to testify soon after the publication of The Genesis Strategy in front of the House Subcommittee on the Environment and the Atmosphere.

Given an increased reliance of Americans on a stable climate, Schneider argued that increased climatic variability was taxing existing technological and agricultural systems to a breaking point. Aware of the deficiencies of current climate models to account for the complicated feedback mechanisms of the global climatic system, he testified that it was crucial to change the “political consciousness” of the United States and overcome the short-term perspective and whimsical interests of policy makers.

“The worst mismatch in the future I see is the political system, whether it socialist or capitalist or totalitarian or democratic … is to short-term issues,” he cautioned.

While he could not specifically address whether the climate would change for the worse in the near future, he did believe that climate change issues provided a “sort of last-ditch symbol” for governments to realize the importance of thinking on generational time-scales.”

The Genesis strategy (1976 edition) | Open Library

Why this matters

We really knew enough by the late 1970s to be seriously worried, and to act. That “we” didn’t become aware until the late 80s, and have NEVER acted, is only partly down to human willingness to ignore problems/procrastinate. There have been wildly successful campaigns to confuse, to delay. Oh well.

What happened next

Schneider and Brown kept on trucking. Schneider, a mensch, died in 2010, just when we needed him the most.

May 7, 1966 – scientist warns public about carbon dioxide build-up…

On May 7 1966, Roger Revelle the noted American scientist had a story in the popular news magazine Saturday Review on carbon dioxide and the oceans.

In it Revelle wrote

“Human beings are now carrying out a large-scale geophysical experiment which, if adequately documented, may yield a far-reaching insight into the processes determining weather and climate. We must not forget, however, that even a relatively small rise in the average annual temperature of the atmosphere might be accompanied by other more serious changes, for example, shifts in the position or the width of belts of low rainfall.”

To be clear – he was not yet saying “watch out”, as others soon would be. Just before this quote he wrote

“In general, our attitude toward the changing content of carbon dioxide in the atmosphere that is being brought about by our own actions should probably contain more curiosity than apprehension.”

Why this matters

We need to remember that people have been warning about the build-up of carbon dioxide for an extremely long time as a potential problem.

Revelle, we should say was one of the founders of the climate issue having written with Hans Seuss about the way in which the oceans might not be soaking up as much co2 as the dogma suggested, and having hired Charles David Keelng whom he found very irritating. (see, Joshua Weiner’s book) 

What happened next 

Revelle kept researching and writing. Other people kept researching and writing. The climate issues slowly, painfully, worked its way up the policy agenda, but didn’t really get down until 1988.

May 5, 1953 – Western Australian newspaper carries “climate and carbon dioxide” article

On May 5 1953, yes, 1953, The West Australian newspaper had a short piece with Gilbert Plass, warning the American Geophysical Union about the build-up of. carbon dioxide…

Image from Brad Johnson’s excellent site

Plass was a geochemist who had read Guy Callendar and understood what he was talking about.

Why this matters

Let’s not pretend that 1988 was the first time anyone heard about climate change. That said, this sort of “we were warned” thing can be a little bit unfair. Because there are all sorts of potential threats, potential problems in the world. And if we responded to all of them, instantly with alarm, we’d never get anything done.

But certainly, I think by the late 60s, early 70s, we did know enough to be concerned. And we didn’t act in accordance with that concern. And here we are.

What happened next?

Plass kept on for a little while, and even attended the 1963 Conservation Foundation meeting in New York. But he didn’t do further climate work. There’s a good account of him in Alice Bell’s “Our Greatest Experiment,” btw.

Denial International processes IPCC Predatory delay Science Scientists

April 19, 2002 – Exxon got a top #climate scientist sacked.

On the 19th of April 2002, the chair of the IPCC, Bob Watson failed to get a second term as chair, even though he wanted one, and (almost) everyone else wanted him to have it. 

As per the Guardian’s coverage

“At a plenary session of the Intergovernmental Panel on Climate Change (IPCC) in Geneva, Robert Watson, a British-born US atmospheric scientist who has been its chairman since 1996, was replaced by an Indian railway engineer and environmentalist, R K Pachauri.

Dr Pachauri received 76 votes to Dr Watson’s 49 after a behind-the-scenes diplomatic campaign by the US to persuade developing countries to vote against Dr Watson, according to diplomats. The British delegation argued for Dr Watson and Dr Pachauri to share the chairmanship.

The US campaign came to light after the disclosure of a confidential memorandum from the world’s biggest oil company, Exxon-Mobil, to the White House, proposing a strategy for his removal.”

[see also the Ecologist in 2018]

tt’s an example of how the Intergovernmental Panel on Climate Change works – the word to look for is governmental. 

Why this matters. 

We’re not getting the politics- free science, which the denialists say they want. We’re getting the science that has been deemed acceptable to the politicians who are often little more than Meat Puppets for vested interests.

And this is a very, very familiar story.

What happened next?

The IPCC has kept going. The message hasn’t changed. Except the time horizons keep shrinking (have shrunk to nowt).

April 2, 1979 – AAAS workshop in Anaheim begins…

On this day, April 2 1979. Yes, the same year, the American Association for the Advancement of Science started a four day workshop in Anaheim, Maryland. 

The following from the rather good recent Verso book “The Great Adaptation” helps set the scene

“The US Department of Energy was no longer willing to overlook the climate question. In collaboration with the American Association for the Advancement of Science (AAA) the leading US scientific body and publisher of the journal Science, it financed a research programme on the social and economic impacts of climate change. Roger Revelle and Stephen Schneider were each involved in organising the programme, which in 1979 resulted in the first international conference dedicated to the social sciences of global warming. This seminar, held in Annapolis, Maryland, sought to bring together speialisgts in economic history, anthropology, economics and political science to think through the consequences of global warming and the responses it demanded: Schneider, Revelle, Kellogg, Orr Roberts, Kenneth Hare and Crispin Tickell all took part…”

(Felli, 2015/2021: p44)

Why this matters. 

Again? I keep banging on about the late 1970s. There’s a method to my madness, which you’ll hopefully read about in a gasp yes, book at some point. 

What happened next?

More studies, but then basically, with the coming of the Reagan administration in 1981, the funding dried up, and Reagan appointees tried, for a few years, at least, to silence the climate scientists. See, for example, what happened to James Hansen in 1981 after his front page story in the New York Times. By the mid-80s, this became much harder, and eventually they had to move to plan B…
