I first read about the Greenhouse effect in Isaac Asimov’s “Intelligent Man’s Guide to Science”, which my parents must have bought in 1960 when it came out.
It wasn’t exotic, cutting edge research.

The fossil fuel industry funded some of the world’s most foundational climate science as early as 1954, newly unearthed documents have shown, including the early research of Charles Keeling, famous for the so-called “Keeling curve” that has charted the upward march of the Earth’s carbon dioxide levels.
A coalition of oil and car manufacturing interests provided $13,814 (about $158,000 in today’s money) in December 1954 to fund Keeling’s earliest work in measuring CO2 levels across the western US, the documents reveal.
Keeling would go on to establish the continuous measurement of global CO2 at the Mauna Loa Observatory in Hawaii. This “Keeling curve” has tracked the steady increase of the atmospheric carbon that drives the climate crisis and has been hailed as one of the most important scientific works of modern times.
The fossil fuel interests backed a group, known as the Air Pollution Foundation, that issued funding to Keeling to measure CO2 alongside a related effort to research the smog that regularly blighted Los Angeles at the time. This is earlier than any previously known climate research funded by oil companies.
In the research proposal for the money – uncovered by Rebecca John, a researcher at the Climate Investigations Center, and published by the climate website DeSmog – Keeling’s research director, Samuel Epstein, wrote about a new carbon isotope analysis that could identify “changes in the atmosphere” caused by the burning of coal and petroleum.
“The possible consequences of a changing concentration of the CO2 in the atmosphere with reference to climate, rates of photosynthesis, and rates of equilibration with carbonate of the oceans may ultimately prove of considerable significance to civilization,” Epstein, a researcher at the California Institute of Technology (or Caltech), wrote to the group in November 1954.
Experts say the documents show the fossil fuel industry had intimate involvement in the inception of modern climate science, along with its warnings of the severe harm climate change will wreak, only to then publicly deny this science for decades and fund ongoing efforts to delay action on the climate crisis.
“They contain smoking gun proof that by at least 1954, the fossil fuel industry was on notice about the potential for its products to disrupt Earth’s climate on a scale significant to human civilization,” said Geoffrey Supran, an expert in historic climate disinformation at the University of Miami.
“These findings are a startling confirmation that big oil has had its finger on the pulse of academic climate science for 70 years – for twice my lifetime – and a reminder that it continues to do so to this day. They make a mockery of the oil industry’s denial of basic climate science decades later.”
Previous investigations of public and private records have found that major oil companies spent decades conducting their own research into the consequences of burning their product, often to an uncannily accurate degree – a study last year found that Exxon scientists made “breathtakingly” accurate predictions of global heating in the 1970s and 1980s.
The newly discovered documents now show the industry knew of CO2’s potential climate impact as early as 1954 via, strikingly, the work of Keeling, then a 26-year-old Caltech researcher conducting formative work measuring CO2 levels across California and the waters of the Pacific ocean. There is no suggestion that oil and gas funding distorted his research in any way.
The findings of this work would lead the US scientist to further experiments upon the Mauna Loa volcano in Hawaii that were to provide a continual status report of the world’s dangerously-rising carbon dioxide composition.
Keeling died in 2005 but his seminal work lives on. Currently, the Earth’s atmospheric CO2 level is 422 parts per million, which is nearly a third higher than the first reading taken in 1958, and a 50% jump on pre-industrial levels.


Heard about Global Warming circa 1956. Saw arctic glaciers in 1973 which were gone around the time that Google Earth became available.
I read a lot of SF as a kid in the 1960s, including the nerdy “hard” SF that reflected the known physics of gravity, celestial mechanics, planetary development, etc. That’s how I was first exposed to knowledge of oceans without lunar tides, different atmospheric compositions (playing up the difference between the likes of a cold Mars-like planet vs. one with an atmospheric blanket like Earth), Lagrange points, gravitational slingshots, etc.
Very timely for me — I’m teaching a class on climate, including a student who is a (very self-confident) climate denier. They also believe the January 6 attack on the Capitol was a Democrat false-flag operation…
big crossover between climate denial and election denial
