June 6, 1957 – CO2 build up studied by Charles David Keeling

On this day, June 6th, 1957, Charles Keeling submits a paper.

Geochimica et Cosmochimica Acta Volume 13, Issue 4, 1958, Pages 322-334 Geochimica et Cosmochimica Acta 

The concentration and isotopic abundances of atmospheric carbon dioxide in rural areas 

Charles D Keeling ∗ Division of Geological Sciences, California Institute of Technology, Pasadena, California U.S.A. Received 6 June 1957,   https://doi.org/10.1016/0016-7037(58)90033-4 

The amount of carbon dioxide in the air was 313ppm.  As of 2026, 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 for this was that after World War Two, it became possible to study the world with more precision and broader scope, thanks to radar, sonar, jet engines etc.

The specific context was that in 1950 the idea of an International Geophysical Year was proposed. And also by the mid 50s, people like Gilbert place, Charles Keeling, Roger Revelle and the Swedes, Ericsson and Rossby and so forth, were talking about carbon dioxide build up as a possible influence on the atmosphere, and this submission of this paper is part of that context. 

What I think we can learn is this: by the mid-late 50s, it was obvious that CO2 was indeed building up and that some people could foresee that there might be serious trouble ahead. 

What happened next: 

Four months after this, Sputnik was launched…

Roger Revelle was able to shake the money tree and get funding for measurement of carbon dioxide build-up, with stations in Hawaii and Antarctica (it was not necessarily expected that global levels would be increasing).

May 29, 2025 – Daughter sues Exxon for mother’s heat death

One year ago, on this day, May 29th, 2025,

May 29 2025 case filed against Exxon etc by daughter of woman who died of hyperthermia in 2021 heat dome – https://climatecasechart.com/wp-content/uploads/case-documents/2025/20250529_docket-25-2-15986-8-SEA_complaint.pdf

The amount of carbon dioxide in the air was roughly 427ppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was that from the late 70s, Exxon was well aware of the carbon dioxide threat, and had even helped oceanographers take samples of CO2 on their oil tankers, and had made many predictions and presentations for the C suite. But Exxon decided in the mid 1980s that it would change its stance on the reality of carbon dioxide build up, and it became one of the chief proponents and funders of outfits like the Global Climate Coalition, established in 1989 to resist both domestic US and international climate policy. And Exxon also funded various denialist groups, so much so that in 2006 the UK Royal Society had published an open letter asking them to knock it off. 

Exxon was also instrumental in the Dubya Bush White House 2001 to 2008 especially with their apparatchik in the CEQ writing climate policy and spreading denial.   

The specific context was that we’re now getting the long predicted weather anomalies, disasters sometimes happening much sooner than the scientists had thought, because, well, that’s nonlinear patterns for you. And what do you do when you’ve been hit by one of these well, you sue, if you can. You use court to try and do what the politics hasn’t been able to do. 

What I think we can learn from this is that most court cases fail, but that doesn’t mean you don’t use it as one of your venues for seeking justice, I guess. 

What happened next. 

On April 9 this year –

State Court in Washington Denied Fossil Fuel Defendants’ Request to Stay Case Pending Supreme Court’s Resolution of Boulder

Defendants’ motion to stay proceedings denied.

A trial court in Washington State denied fossil fuel industry defendants’ motion to stay proceedings pending the outcome of the U.S. Supreme Court’s review of Suncor Energy (U.S.A.) Inc. v. County Commissioners of Boulder County. The Washington trial court found that the outcome of the Boulder proceedings was “far from certain,” including whether the Court would issue a substantive ruling and whether the Court would resolve the issues in this case. The court also found that a potentially 14-month stay could prejudice the plaintiff’s ability to conduct discovery, that the public interest weighed against the stay, and that potential prejudice to the defendants was mitigated by the fact that some documents had already been preserved and some discovery had already been conducted in other similar cases.

May 26, 1977  – “Forest loss poses threat to Earth” (Do bears shit in those forests?)

Forty eight years ago, on this day, May 26th, 1977, The Grand Island Independent (Nebraska) runs a a story on p34, “Forest Loss Poses threat to Earth”

The amount of carbon dioxide in the air was roughly 333ppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was that by the mid-1970s various types of scientists were beginning to look at atmospheric carbon dioxide build-up and go ‘uh oh’. There was a side debate about whether the carbon dioxide problem was down to fossil fuels or fossil fuels and other issues (deforestation).

What I think we can learn from this is that we have had fifty years of this stuff. And we just keep making things worse. Because we are not that smart. And we think we can dump the costs on other people/species. 

What happened next. We dumped the costs on other generations, until it was us.

Carbon Dioxide Removal technosalvationism United States of America

May 23, 2023 JPMorgan Chase and Climeworks CDR agreement

Three years ago, on this day, May 23rd, 

“JPMorgan Chase and Climeworks landmark CDR agreement heralds new standard in voluntary carbon market for direct air capture”

The amount of carbon dioxide in the air was roughly 382ppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was that with the failure to use existing technologies like nuclear and renewables to reduce carbon emissions, we are now in such deep shit that we’re having to invent, and take seriously, fantasy technologies like Direct Air Capture.

The specific context was that direct air capture has been having a “moment” for the last few years. Reality is setting in, but you get these hysterical announcements about market making and investment and you’re supposed to take it seriously. But what we learn is that carbon dioxide removals is the emperor’s new clothes. It’s a farce. 

What I think we can learn from this. Any crap gets believed in, if it is convenient. Bearded sky gods, Direct Air Capture, you name it. 

What happened next.  I haven’t been able to find anything more recent than 2024. Maybe the money is still ‘there’. But, you know these agreements, they last for a couple of years, and then they get quietly dropped, and another agreement comes along.

May 22, 1979 – Frank Press asks NAS to look into climate change. …

Forty seven years ago, on this day, May 22nd, 1979,

President Carter’s chief scientific adviser Frank Press requests NAS to look at CO2

[following MacDonald and Pomerance] Finally, weeks later, MacDonald called to tell him that Press had taken up the issue. On May 22, Press wrote a letter to the president of the National Academy of Sciences requesting a full assessment of the carbon-dioxide issue. Jule Charney, the father of modern meteorology, would gather the nation’s top oceanographers, atmospheric scientists and climate modelers to judge whether MacDonald’s alarm was justified — whether the world was, in fact, headed to cataclysm.

https://www.nytimes.com/interactive/2018/08/01/magazine/climate-change-losing-earth.html

The amount of carbon dioxide in the air was roughly 3xxppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was that from the mid 1970s, various scientists in the United States – we’re talking Gordon MacDonald, Alvin Weinberg, Roger Revelle, perhaps a few others – had been able to lobby the ERDA to start taking climate change seriously and put pressure on the higher-ups in the science establishment in the United States, especially President Carter’s Chief Scientific Advisor, Frank Press. And Press, on this day, asked the National Academy of Sciences to have a look at the issue with new eyes to see if the fears of the carbon dioxide action advocates were fair and justified. 

The specific context was that Chief scientists understandably want to make sure a problem they are being told about is actually a problem, before they go to their political pay masters with it. That’s fair and legitimate. 

What I think we can learn from this. That for all reasonable circumstances, we knew enough by the late 1970s to be taking action.

What happened next. The NAS did the study. This was the Charney report, and it said, “yeah, if we keep tipping carbon dioxide into the atmosphere there’s absolutely no reason not to believe that the temperature will go up significantly and that will cause a world of pain” and Press clearly didn’t like that, didn’t think it should be something on Carter’s agenda, especially in the following year, which was an election year.

May 19, 1967 – Debate on Pollution, Rockefeller University with Barry Commoner, Rene Dubois, Athlene Spilhaus

Fifty nine years ago, on this day, May 19th, 1967,

Debate on Environmental Pollution, Rockefeller University, New York, Barry Commoner, Rene Dubois, Athlene Spilhaus.

The amount of carbon dioxide in the air was roughly 322ppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was that the pollution issue is beginning to break through beyond simply air pollution in cities. People are beginning to think about the long term, longer term implications. This is partly due to the fact that you’ve had books like Silent Spring published in 1963 based on the 1962 New Yorker articles and a flurry of other books. So you have three interesting people here talking at Rockefeller University in New York, and one of them is Spilhaus, who had studied under Roger Revelle, and whose cartoons about science had appeared in newspapers around the United States, including the greenhouse cartoon in 1958 Spilhaus was well aware of the dangers of carbon dioxide buildup.  Commoner’s book Science and Survival had come out the previous year and it had also had a section on carbon dioxide build-up…

The specific context was that the Vietnam War was raging, the ‘hippies’ were protesting etc.

What I think we can learn from this intellectuals had been saying what was at stake for a very long time. The problem with intellectuals, well, there are many, but one of them is they’re not very good at helping social movements think through the implications of those social movements’ current strategies for maintaining hope or momentum or whatever, and how those strategies might hinder the growth and expansion of the social movement framing.

No one particularly is; I could give it a go, but I’m too idle and dispirited. 

What happened next.  Commoner ran for President in 1980.

The emissions kept climbing.
Btw, if you’re reading this in the US and can get hold of  a recording and transcript, that’d be ace – would be fascinating to know if carbon dioxide build-up came up…

May 14, 1972 – An Observer journo is “funny” on climate…

Fifty four years ago, on this day, May 14th, 1972, American journalist John Crosby was making fun of ecology. Smart fella.

The amount of carbon dioxide in the air was roughly 327ppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was that Crosby had been a big deal in the US, before moving to the UK in the 60s. He’d fronted one of those ‘harrumph, the green freaks are wrong’ documentaries, that I should write about some day.

The specific context was that the Limits to Growth report had come out, the Stockholm Conference was coming up, and harrumphing was what Sensible People were doing. It is always “punch a hippy” day, isn’t it?

What I think we can learn from this. To hell with these assholes.

What happened next. The harrumphing continued. The old white men could never admit they were wrong – their world would implode. As to the actual world burning, well, what of it?

May 10, 1989 – Bush announces conference

Thirty seven years ago, on this day, May 10th, George Bush says he will hold a conference.

The amount of carbon dioxide in the air was roughly 353ppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was thatAmerican politicians had been warned about the climate threat since the late 70s. Under Reagan/Bush between 1981 and 1989 these threats had been largely ignored until it was no longer politically feasible to do so on. 

The specific context was that in August 1988 on the campaign trail, George H.W. Bush,feeling vulnerable on environmental issues, because his Democratic opponent, Michael Dukakis, had a record to stand on, proclaimed that he would call an international conference on climate change in his first year in office. 

The other specific context is that – he – Bush had been caught trying to suppress the scientific and alter the scientific assessment of a NASA scientist, James Hansen, and so was needing to do some reputational repair. 

What I think we can learn from this is that when leadership was needed, we got Bush instead.

What happened next. The conference was finally held in 1990 and somebody somehow “forgot” in inverted commas, to invite the head of the IPCC, Bert Bolin.

May 9, 1989 – the Brits want a global climate pact. The US? Not so much…

Thirty seven years ago, on this day, May 9th, 1989, Crispin Tickell tried to move things along. 

Boston Globe, May 10 1989.

The amount of carbon dioxide in the air was roughly 353ppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was that Tickell was a career diplomat. In 1975 he had done a sabbatical at Harvard University and wrote his thesis on Climatic Change and International Affairs. He could see what carbon dioxide build-up would do to geopolitics. He tried repeatedly to get Margaret Thatcher to be concerned about the question. Eventually, in 1988 he succeeded.

The specific context was that in the second half of 1988 the problem had become an issue. Thatcher gave a speech at the Royal Society in late September 1988 that was, in effect, the starting gun for international diplomacy. The administration of George H.W. Bush, however, was dragging its heels.

What I think we can learn from this. There was a chance to fix this – or if not actually fix it, then manage it. To buy us extra time. Instead we went lead head and lead foot off the cliff. Oh well.

What happened next. The US threatened to boycott the Earth Summit if targets and timetables for emissions reductions by rich countries was in the text of the Climate Treaty. This threat worked, the targets and timetables weren’t in, and we have spent the last 34 years trying to get them in.

May 8, 1989 – Bush Administration exposed gagging climate scientist James Hansen

Thirty seven years ago, on this day, May 8th, 

https://www.columbia.edu/~jeh1/Documents/NYTimes.1989Week07May.pdf

“All three networks on May 8, 1989 did greenhouse effect stories based on Senate sub-committee hearings in which NASA scientist James Hansen told Senator Al Gore that he had been ordered by the Bush administration to change the conclusions in written testimony regarding the seriousness of global warming.”

Sachsman 2000:5)

And

“More specifically, on 8 May 1989, the Office of Management and Budget confirmed that it had altered the Congressional testimony of NASA’s James Hansen, thereby weakening his conclusion that enough was known about the phenomenon to justify immediate action. The Whitehouse defended this action by claiming that it wanted to avoid the appearance of policy disagreements within the Administration. The political fallout from this episode was considerable, not only within the United States but also internationally.”

Rowlands (1995) Page 76 

The amount of carbon dioxide in the air was roughly 353ppm. As of 2026 it is 430ppm, but check here for daily measures. 

The broader context was that scientists had been warning politicians and had mostly been simply ignored. But from 1988 onwards, ignoring came with costs.

The specific context was that James Hansen had given testimony to a Senate Committee on 23rd of June, 1988 and this, as much as anything else, had set the ball rolling. Happy dogs. But new president, George H.W. Bush was opposed to an environmental agenda. I think it’s fair to say, despite his promises on the campaign trail. And here we see evidence of Hansen’s testimony being altered and sidelined, and this being exposed by Democratic senator from Tennessee, Al Gore.

What I think we can learn from this is that if you’re a politician, you can ignore people, but actually actively changing their words… well, someone is going to leak it, and you’re going to get in hot water. 

What happened next. Hansen decided just to go back to doing his science, understandably, but he changed his mind in 2005 and has since then been an incredibly effective, active scientist and advocate for action. Bush continued, and scuppered the chance of any strong response to the climate threat by threatening to boycott the 1992 Rio Earth Summit, if targets and timetables for emissions reductions by rich countries were in the treaty on climate that was up for signature. This worked. Targets and timetables for rich countries were taken out of the text. And here we are.
