Forty four years ago, on this day, February 19th, 1981, Nature publishes an article, by Wendy Barnaby, about an Earthscan meeting the previous week in Stockholm,
The amount of carbon dioxide in the air was roughly 340ppm. As of 2025 it is 427ppm, but check here for daily measures.
The context was that the OECD and the IEA – and other bodies – were beginning to hold meetings about energy and environment and especially climate, in the context of the second oil shock the tail end of the 70s, thanks to the overthrow of the Shah.
The other context was that the United States Council on Environmental Quality had been trying to get things moving, but now Reagan was present with his goons, (and see the end of the article before the greenhouse one in the screengrab above! – it all looked a little unsure about what would happen.
And this is also in the context of the First World Climate Conference, which had taken place in February of 1979, Nature had an interesting relationship with carbon dioxide build up, shall we say, with its erstwhile editor, John Maddox, being a vehement opponent of the theory up until and including 1987 (he seems to have climbed down from this by 1995).
What I think we can learn from this is that in the late 70s, early 80s, there was a flurry of activity, awareness, and slowly growing consensus.
What happened next There was a flurry of reporting in New Scientist, the FT etc. A documentary, “Warming Warning”, by Richard Broadwas broadcast the end of that year, in part inspired by this report in Nature and other accounts.
