August 9, 1955 – Canadian physicist Gilbert Plass submits his paper

Sixty nine years ago, on this day, August 9th, 1955, Gilbert Plass submits a paper… You can read it here.

(Manuscript received August 9 1955

The amount of carbon dioxide in the air was roughly 314ppm. As of 2024 it is 424ppm, but check here for daily measures. 

The context was that Plass had been talking, researching, writing about CO2 buildup for a while. He made public statements in May of 1953 [see my Conversation article], at the American Geophysical Union that went viral. And here he was submitting an article to Tellus, a Swedish academic journal. (Tellus was the watering hole for atmospheric physics those people at that time.) 

What we learn is that smart people could see what was happening. 

What happened next. Plass wrote that paper. He wrote another paper, I think, in 1959. And he also had an article in Scientific American in 1959. That, btw, was advertised in the Observer.

May 24, 1953 – NYT on “How industry may change climate”

Seventy one years ago, on this day, May 24th, 1953, the New York Times reported on Gilbert Plass’s statements at the American Geophysical Union’s meeting a couple of weeks earlier. The article was by Waldemar Kaempfert, who’d write something else on the topic in October 1956, just before his death.

https://www.nytimes.com/1953/05/24/archives/how-industry-may-change-climate.html

The amount of carbon dioxide in the air was roughly 313ppm. As of 2024 it is 425ppm, but check here for daily measures. 

The New York Times makes explicit mention of carbon dioxide buildup from industry as something that will heat the planet. This is from their science writer Walter Kaempffert.

The context is that a couple of weeks later earlier, Gilbert Plass, a Canadian physicist had made a startling presentation to the American Geophysical Union, and this had travelled around the world [Conversation article link].

What we learn is that it’s been 71 years since the warnings started coming from people who weren’t “merely” steam engineers. 

What happened next – It was taken seriously, as it were, in the 1950s, then seemed to fall off for 10 years. And then came back in the late 60s and then fell off again, came back in the late 80s. And here we are 35 years after that, having increased our emissions by about 70%.

May 13, 1957 – Guy Callendar to Gilbert Plass on how easy it is to criticise, how hard to build theories

Sixty seven years ago, on this day, May 13th, 1957, English steam engineer Guy Callendar, who had been pointing to carbon dioxide build-up as an explanation for increased global temperatures since the late 1930s, wrote to Gilbert Plass, who in 1953 had brought the problem to global attention (see my Conversation piece here).

How easy it is to criticise and how difficult to produce constructive theories of climate change! and ““A point of special interest is the large discrepancies between the apparent increase of atmospheric CO2 given by the air-CO2 observations . . . and the predicted increase derived from the size of the exchange reservoirs as now revealed by radio carbon measurements.”

Letter from Callendar to Plass 13 May 1957 (Fleming, 2007: chapter 5)
Guy Callendar

The amount of carbon dioxide in the air was roughly 315ppm. As of 2024 it is 425ppm, but check here for daily measures. 

The context was that Guy Callendar had been banging on about climate change and carbon dioxide buildup since 1938. And Plass had been doing the same since 1953. The two were corresponding and Callendar made a very good point about how the more conventional/mainstream/whatever people were resentful of an outsider committing that terrible crime of being right and proving the experts to be wrong. 

What we learn is that sometimes the experts are wrong. Other times they’re right but sometimes they are wrong. Don’t expect them to applaud you. 

What happened next Callendar had another great piece in 1960 – see here. He died in 1964. Plass kept writing about climate for a few more years but eventually moved on to other things. And the emissions kept climbing.

December 30, 1957 – a letter from Gilbert Plass to Guy Callendar

Seventy six years ago, on this day, December 30, 1957, the English steam engineer Guy Callendar wrote to the Canadian physicist Gilbert Plass

“Plass wrote to Callendar that Revelle and Suess and Arnold and Anderson had “attacked the carbon dioxide climatic theory ‘quite vigorously’ at a meeting earlier this year.”

They claimed that it was absolutely impossible to have had a sufficient increase in the CO2 amount in this century for the reasons that were given in their articles. I think you have pointed out several ways that their conclusion could be in error and I feel that there are still several possible explanations. 64 (Fleming 2007, p.81)

The amount of carbon dioxide in the air was roughly 314ppm. As of 2023 it is 421ppm, but check here for daily measures. 

The context was that American scientists who were studying carbon dioxide build-up and had been writing about it were still not quite sure what was going on. Understandably – if all the answers were obvious you wouldn’t need to explore anything, and that’s not how science works 

Guy Callendar had written the first serious “carbon dioxide is causing climate change” scientific article in 1938 presented it, to muted response, at the Royal Meteorological Society. 

Gilbert Plass was, more than anyone, responsible for putting carbon dioxide squarely on the agenda with his 1953 statements at the American Geophysical Union and then onwards in 1956 with his articles

What I think we can learn from this is that it’s always a messy murky picture in the early days of any issue. Later on it looks like a procession, but a good historian will try to remember the messiness and make it understandable, without removing the messiness.

Obviously that’s an ongoing process that we need to remember how little we knew and how confused the picture was.

What happened next

Callendar kept writing articles and letters. He died in 1964.

Gilbert Plass continued to be engaged for another few years on the climate issue and then wasn’t.

Roger Revelle died in 1991, having spent a long time trying to get the US state and others scientists politicians to take climate change seriously/

November 27, 1956 – New York Times science writer who covered C02 build-up dies.

Sixty seven, on this day, November 27,1956 Waldemar Kaempffert, New York Times science writer dies.

A month earlier, on October 28, the Grey Lady had run this below.

The amount of carbon dioxide in the air was roughly 314ppm. As of 2023 it is 419ppm, but check here for daily measures. 

The context was that Kaempfert had been a journalist for a long time, and he had done a couple of really good articles in the New York Times about industry warming the world. He was probably good mates with Gilbert Plass. He had written the NYT article about Gilbert Plass’s comments at the AGU in May 1953.

What I think we can learn from this

Smart people were switched on to the threat in the 1950s. It wasn’t rocket science.

What happened next

Walter Sullivan became the chief science writer at The New York Times. Sullivan was heavily involved in reporting on the International Geophysical Year and at that point became aware of the potential problem of climate change from carbon dioxide build-up.

May 18, 1953 – Newsweek covers climate change. Yes, 1953.

Seventy years ago, on this day, May 18, 1953, the American weekly magazine Newsweek ran a snippet about the ‘carbon dioxide is building up and we should watch out’ statement of Gilbert Plass at the American Geophysical Union (see May 5) 

Newsweek; New York Vol. 41, Iss. 20,  (May 18, 1953): 75  https://archive.org/details/sim_newsweek-us_1953-05-18_41_20/page/74/mode/2up?view=theater

The amount of carbon dioxide in the air was roughly 313ppm. As of 2023 it is 423ppm, but check here for daily measures. 

The context was that two weeks previously, Gilbert Plass had made some very eye-catching statements at the American Geophysical Union that had been picked up and broadcast. This is the first report by Newsweek that I can find and it was followed shortly after, by something from Time.   

What I think we can learn from this

This is the moment in which the carbon dioxide theory of climate change really starts to enter into popular discourse. The context was that people were sure the world was getting hotter. It was a question of why. 

What happened next

Plass did his scientific work and in 1955/56 released papers about the carbon dioxide theory of climate. There was a further paper in Scientific American in 1959. There’s a direct line between Plass and Guy Callendar with whom Plass corresponded.

May 5, 1953 – Gilbert Plass launches the carbon dioxide theory globally

Seventy years ago, on this day, May 5, 1953, the modern “carbon dioxide is a greenhouse gas” era began.

The amount of carbon dioxide in the air was roughly 313ppm. As of 2023 it is 420ppm, but check here for daily measures. 

The context was that Plass had become interested in the question of carbon dioxide buildup while being paid by Ford Motor Company. He had corresponded with British steam engineer and scientist Guy Callendar. Plass only looked at how carbon dioxide actually functions in the real world, and whether the bands become saturated or not (they don’t).

What I think we can learn from this

This is the pivotal moment, when someone takes the carbon dioxide theory and starts hammering it out…

This  classic warning went around the world. It was eye-catching, and it was syndicated, certainly in Australia, New Zealand and elsewhere. And it probably helped. George Wendt in his writing in the UNESCO magazine Courier, which also got syndicated. So you can see these couple of people speaking up about it.  

Plass’s warning also popped up in Time, Newsweek, and elsewhere, this was really consequential. 

What happened next

Plass kept writing and thinking about climate build up carbon buildup. In 1956, he had an academic article published in Tellus, the Swedish scientific journal.- “the  carbon dioxide theory of climate change”, and also a popular article in the American Scientist.  

He was there in 1961 at the New York Academy of Sciences/American Meteorological Society meeting and at the 1963 Conservation Foundation meeting. But that was his last gasp on the topic…

April 23, 1954 – Irish Times runs carbon dioxide/climate story. Yes, 1954.

Sixty nine years ago, on this day, April 23, 1954, the Irish Times ran a brief article about climate change and carbon dioxide. Yes, 1954. 

It came from a journalist/scientist, Gerald Wendt, who had been writing for the UNESCO Courier.

23 April 1954 Irish Times article

The amount of carbon dioxide in the air was roughly 313ppm. As of 2023 it is 420ppm, but check here for daily measures. 

The context was

In May 1953 Gilbert Plass had said to the American Geophysical Union meeting, in essence – “you know, that Brit, Guy Callendar who said, before the war, that carbon dioxide increase in the atmosphere was leading to warming?? “ell, he’s right.”

What I think we can learn from this

The idea that carbon dioxide build up could be a problem was in the air (sorry, not sorry) for a long time.

What happened next

Wendt’s writing got syndicated/serialised elsewhere, including in the colonies.

By 1956 Plass had published on the subject. Others were doing likewise.

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 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.
