The amount of carbon dioxide in the air was roughly 338ppm. As of 2026 it is 428ppm, but check here for daily measures.
The broader context was by about 1976-77 especially people within the senior levels of the United States science establishment – I’m thinking specifically of Alvin Weinberg, but it’s not just him – were really thinking hard about climate change from carbon dioxide build-up. So perhaps one of the key documents that I need to think about more is the August 1976 report from Oak Ridge.
Anyway, there had been the Miami Beach meeting in 1977 and now more and more conferences and meetings, scientific workshops, all in the hope that the politicians could be persuaded to take it all seriously. And at this point, of course, the idea of synfuels were still in the mix as a response to the second oil shock.
The specific context was that the first world climate conference had happened, and there was money from the Department of Energy for these sorts of workshops.
What I think we can learn from this is that we knew enough in 1980 to be taking action (as per the CO2 Newsletter).
What happened next. More meetings. The crucial event was the election of Ronald Reagan that basically put the kibosh on all the effort, or most of the political policy efforts within the US.
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.
