CO2 Newsletter Editorial: “The new decade begins on an optimistic note”

Every issue of the CO2 Newsletter had an editorial. They are William Barbat’s attempt to share (and shape) situational awareness.

Here, in March 1980, he is breathing a sigh of relief because it seems the various elements of the state (the Department of Energy, the Council on Environmental Quality) is finally beginning to get its act together. Sadly, all that would be wrecked from November 1980, with the coming of the Reagan gang. (And yet, Barbat persisted. The man had brains and guts).

The new decade begins on an optimistic note as the CO2-greenhouse problem is beginning to receive deserved attention in scientific, political, and economic institutions. Also this particular environmental issue may unite former adversaries in a common effort. David Burns, head of the AAAS Climate Program, has noted a great increase in the number of major papers which are being prepared for publication on the CO2 problem. Also our growing readership indicates to us that the Newsletter is fulfilling its role of enlightenment. Soon a European distributorship for the Newsletter may be established. Most heartening though is the apparent absence of polarization toward the CO2 problem.

Still much skepticism remains concerning the seriousness and urgency of the CO2 problem. Although a rapidly growing number of scientists feel that we now have sufficient knowledge of impending CO2– induced impacts on which to base energy policies, others feel that much more concrete evidence must first be gained throughout the world to substantiate theories and models. Some non-technical people grossly misinterpret this skepticism as representing negative proof.

From the very beginning, much work on the CO2 problem has been performed under adverse conditions or severe financial restraints. Tyndall had to trouble-shoot his galvanometers and have them reconstructed in order to measure the absorption and radiation of heat by CO2. He found that the green dye used in the silk covering of the copper coils of the most delicate instruments of his day contained some iron compound which caused the needle to deviate. Arrhenius lacked laboratory determinations of the absorption coefficients for CO2 and water vapor at plus 15 degrees C, and he also lacked the laboratory equipment needed to make the determinations. “Such experiments . . . would require very expensive apparatus beyond that at my disposal.” Ingeniously, Arrhenius used the earth’s atmosphere instead as his laboratory. Ernest Rutherford described the challenges of those days clearly’ “We haven’t the money, so we’ve got to think.”

Modern workers on the CO2 problem seem to be little better off. The federal funding of Keeling‘s invaluable monitoring of atmospheric CO2 concentrations fell victim to the race to put a man on the moon for several months in 1963. The General Circulation Model of Manabe and Wetherald reportedly contained a programming error, which apparently could only be eliminated by a computer rerun which exceeded their resources. Glaciologists are asked to make predictions of future ice sheet behavior from very sparse data. As far as we can tell, the only available forecast of the warming threshold for West Antarctica Ice Sheet destruction relies solely on a temperature datum provided by a map made from Russian observations taken during the International Geophysical Year. Polar research has been funded meagerly by the U.S. in recent years.

Meetings which bring together atmospheric scientists, climate modelers, terrestrial and marine biologists, ocean geochemists, and other workers to analyze the CO2 problem collectively are greatly limited as to frequency and numbers of invited participants. Publications concerning such meetings are usually incomplete and much delayed. Some important results of the scientific analyses are not even available for purchase through normal channels because some agencies seem to act more as a sink than a source of information. Thus, we owe a great debt of gratitude to the relatively small number of scientists who have brought us so much understanding with so little.

December 4, 1893 – John Tyndall dies

One hundred and thirty two years ago, on this day, December 4th, 1893,

In his last years Tyndall often took chloral hydrate to treat his insomnia. When bedridden and ailing, he died from an accidental overdose[79] of this drug in 1893 at the age of 73, and was buried at Haslemere.[80] The overdose was administered by his wife Louisa. “My darling,” said Tyndall when he realized what had happened, “you have killed your John.”[81]

: 1893 John Tyndall dies http://en.wikipedia.org/wiki/John_Tyndall

The amount of carbon dioxide in the air was 294ppm. As of 2025, when this post was published, it is 430ppm. This matters because the more carbon dioxide in the air, the more heat gets trapped. The more heat, the more extreme weather events. You can make it more complicated than that if you want, but really, it’s not. Fwiw, I have a tattoo of the Keeling Curve on my left forearm.

The broader context was that Tyndall had, in the 1860s, proved that carbon dioxide was a greenhouse gas (did he rip off Eunice Foote? Possibly. Probably say some. I am less convinced, fwiw).

What I think we can learn from this – be super careful with potentially lethal cures for insomnia? Er, that’s all I got…

Also, I listened to a podcast where they interviewed the climate scientist Kate Marvel – in her new book she speculates (and she admits this is speculation) that it may not have been an accident…

What happened next? They named a climate centre after him.

What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong? Please do comment on this post, unless you are a denialist, obvs.

Also on this day:

Letter in FT: Global carbon price call is a classic delaying tactic

WHOOP! Another letter in the FT.

Here’s the text-

It would be nice to live in Patrick J Allen’s world (FT letters “Getting mad at oil majors won’t solve energy crisis,” FT Weekend, 18 February). In that world innocent and disinterested oil companies are simply waiting for the world’s governments to agree a global carbon price.

Sadly, this world – the real one- is rapidly overheating. In this world oil companies have spent the last 35 years – from the very start of the climate negotiations – resolutely opposing such measures at both national and international levels. Whether the price is a tax or an emissions trading scheme, oil companies have been key players in the campaign of predatory delay, delaying deferring watering down either via direct lobbying, or by funding groups that deny the basic reality of 19th century physics.

Indeed, the call for a global carbon price is a classic delaying technique, because such a price would take decades to agree, even if it could be (doubtful).

These are decades during which two things would happen. One, the impacts of the carbon dioxide we have already put into the air would accelerate. Second, oil company profits would continue to climb.

Dr Marc Hudson

So, on the 19th century physics bit – before Arrhenius in 1896, there was this –

The French chemist Fourier in 1824/1827, showing that given the Earth’s distance from the Sun, and the temperature of the Earth, there must be *something* trapping heat, as in a greenhouse (see Jason Fleming’s excellent article).

Eunice Foote and John Tyndall in the late 1850s and early 1860s respectively showing that “carbonic acid” (essentially carbon dioxide in solution) traps heat…

On predatory delay –

“Predatory delay is the blocking or slowing of needed change, in order to make money off unsustainable, unjust systems in the meantime. For delay to be truly predatory, those engaged in it need to know two things: That they’re hurting others and that there are other options.”

Why I write

I LOVE the FT – not for its pro-growth, pro-capitalism ideology, but for its intelligence, the facts it displays, the quality of its writers. As Chomsky has said, if you want a tolerably accurate view of the world, read the quality business press (albeit with your bullshit detectors set to maximum settings), because these papers are written for the people who are actually running the show, and they need accurate information, not fairy stories they want to believe or they want/need other people to believe.

And that’s why I put effort into pushing back against bad narratives about climate change that appear in the FT. If the pushback gets published, then it appears in front of people who ‘matter’. As theories of change go, it’s not much, I agree, but at least it’s not going to make things actively worse…

August 23, 1856 –  Eunice Foote identifies carbon dioxide as greenhouse gas

On this day in 1856 American scientist and women’s rights campaigner Eunice Foote illustrated her findings in a paper entitled, “Circumstances affecting the heat of the sun’s rays,” which was accepted at the eighth annual American Association for the Advancement of Science meeting on August 23, 1856 in Albany, NY. Back in the day, what we now call carbon dioxide was known as carbonic acid…

See Alice Bell’s “Our Biggest Experiment” for more about Foote, and also the wikipedia entry linked to above…

On this day the atmospheric carbon dioxide was 285 ppm (see here).  Now it is 420ish- but see here for the latest.

As David Morrow usefully notes

“You can read more about the significance of Foote’s research in Raymond Sorenson’s 2011 article on Foote’s research and his 2018 addendum to it, as well as in Leila McNeill’s 2016 article on Foote’s discovery in Smithsonian Magazine.”

Why this matters. 

An interesting foote-note? (sorry, it was there, had to use it). Good for thinking with around (lack of) opportunities for women/amateurs.

What happened next?

John Tyndall wrote about this a few years later. Had he seen Foote’s work? We will never know. Maybe. Probably.
