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 24, 1894 – Arrhenius starts work…

One hundred and thirty one years ago, on this day, December 24th, 1894,

Swedish scientist Svante Arrhenius, in the midst of a gruesome divorce, started work on his  climate model, Dec 24 1894 ( source for the date is Elizabeth Kolbert “H is for Hope” p12)

The amount of carbon dioxide in the air was 295ppm. 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 Arrhenius was aware of Tyndall’s work on “carbonic acid” in the atmosphere (but not Eunice Foote’s).

The specific context was – he was going through a messy and painful divorce and needed a Project to Distract Himself.

What I think we can learn from this – scientists make sacrifices etc.

What happened next was that Arrhenius published the work. He later got a Nobel Prize for chemistry (for other discoveries).

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.

December 24, 1895 – Arrhenius explains the work that went in…

One hundred and twenty nine years ago, on this day, December 24th, 1895, Svante Arrhenius explains the work that went in…

“His preliminary calculations showed that the required changes in CO2 were in the order of 50%. Hogbom, who was present, confirmed that those changes could have occurred in geological times. It remained, however, to demonstrate this quantitatively. The construction of the model which enabled him to do so occupied him for most of 1895. Writing to a friend at the end of the year, he found it “unbelievable that so trifling a matter has cost me a full year” (5) ”

Svante Arrhenius to Gustaf Tammann, December 24, 1895, Arrhenius Collection, Center for History of Science, Royal Swedish Academy of Sciences, Stockholm in Crawford, E. 1997 Arrhenius’ 1896 Model of the Greenhouse Effect in Context Ambio, Vol. 26, No. 1, Arrhenius and the Greenhouse Gases (Feb., 1997), pp. 6-11

The amount of carbon dioxide in the air was roughly 295ppm. As of 2024 it is 425ppm, but check here for daily measures. 

The context was that Svante Arrhenius had gone through a divorce and partly to distract himself he’d spent a year doing insane calculations about the effects that a doubling of atmospheric CO2 would have. He had produced this work. He had presented this work and it was about to be published. 

What we learn is that in the days before ENIAC computers, if you were a mathematician it was like that joke “Did you hear about the constipated mathematician? He had to work it out with a pencil.” 

What happened next is his work was kind of disregarded thanks to a misunderstanding of how carbon dioxide works in the stratosphere, but it wasn’t lost altogether because some people took it seriously. Then Guy Callendar did the sums also without a computer and presented that work to the Royal Meteorological Society in front of Kenneth Hare and others. 

Fun fact. Arrhenius died in 1927. And Guy Callendar died in 1964, on the same day of the year, October 2nd https://allouryesterdays.info/2022/10/01/october-2-1927-64-svante-arrhenius-and-guy-callendar-die/

May 10, 1931 – Daily Oregonian mentioning greenhouse….

Ninety three years ago, on this day, May 10th, 1931, an Oregonian newspaper provides some facts

The amount of carbon dioxide in the air was roughly 308ppm. As of 2024 it is 425ppm, but check here for daily measures. 

The context was that newspapers love to write stories about the weather and climate – “is it getting hotter?””Is it getting colder?” “boffins are undecided” This is a staple and it’s easy to write and readers have opinions on the weather and will write in.

So it’s not a huge surprise that the Daily Oregonian would run a piece. Nor is it a surprise really that carbon dioxide and Svante Arrnehius would get a mention because although scientists had wrongly dismissed Arrhenius on the basis of assumptions about how carbon dioxide would behave in the stratosphere, his ideas made a kind of intuitive sense for other people. (Now this isn’t to say that all ideas that have been dismissed by scientists which make intuitive sense are right!. But in this case…)

What happened next? Well, there was in England a steam engineer called Guy Callendar beavering away. And a few years later, he would submit the paper and then present it at the Royal Meteorological Society. And that would interest a German called Herman Flohn, and also a Canadian called Gilbert Plass from 1953 onwards. Meanwhile, the emissions climbed. 

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.

December 11, 1895 – Arrhenius reads his “Influence of Carbonic Acid in the Air” paper to Swedish Academy of Science…

On this day, December 11 in 1895,  Swedish scientist Svante Arrhenius read his would-eventually-be-’famous’ paper On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground  at the Swedish Academy of Science. 

It was published the following year

You can read it here – https://www.rsc.org/images/Arrhenius1896_tcm18-173546.pdf

For discussion, see

Hamblyn, R. 2009. The whistleblower and the canary: rhetorical constructions of climate change. Journal of Historical Geography, Vol. 35, pp.223-236

[The amount of carbon dioxide in the atmosphere was 295ppm. At time of writing it was 419ishppm- but for what it is now,well, see here for the latest.]

Why this matters

This has become the touchstone for “how long we’ve known” pieces.

What happened next

Arrhenius’ assumptions (and those whose work he drew on) were challenged by Angstrom et al.  The idea that a build up of carbon dioxide could cause warming was thrown in the dustbin, and – despite Guy Callendar – only really got pulled out in the 1950s…

October 2, 1927/64 – Svante Arrhenius and Guy Callendar die.

On this day, October 2nd 1927, Swedish scientist and Nobel Prize winner Svante Arrhenius died.

The guy who did the back of envelope calculations (big envelope, it took him a year).  

The atmospheric c02 level was 305ppm. It is now about 421ppm.

By coincidence, exactly 37 years later, British scientists and engineer Guy Callendar died. (See here).

On Callendar, James Fleming has done excellent work (link).

[The amount of carbon dioxide in the atmosphere was 316.87ppm. At time of writing it was 421ish ppm – but for what it is now,well, see here for the latest.]

August 13, 1882 – William “Coal Question” Jevons dies

On this day 13 August 1882, William “Coal Question” Jevons died

Eh? What AM I talking about?

Well, Jevons (a very interesting character) had written a book called “The Coal Question” in 1865. In it he pointed out that if you make a procedure more efficient, you don’t actually reduce the total amount of resources used, because when a producer is now using less of a resource, the price drops, more producers enter the market and the total consumption of the resource goes up. This is known as “Jevons Paradox.”


And somebody even made a video about it.

And for more on this, see, http://thinkprogress.org/climate/2011/02/16/207532/debunking-jevons-paradox-jim-barrett/

PS 1882 happened to be the First International Polar Year.

On this day atmospheric PPM was – dunno, 292 ppm, according to the ice cores. Now it is 421ish- but see here for the latest.

Why this matters. 

The rebound effect matters very much

What happened next?

Fourteen years after Jevons died, Svante Arrhenius’s work on the build-up of carbon dioxide was released…
