Fifty years ago, on this day, October 18th, 1974,
Alvin Weinberg, ‘Global Effects of Man’s Production of Energy’, Science 186 (18 October 1974), 205. Weinberg wrote that the world might reach ‘climatological limits’ within 30–50 years. Noting the uncertainty surrounding the results so far, he called for two responses. ‘First, climatologists should recognize the profound implications of this question and do the basic research in global modelling … so that, say 20 years from now, we can base our energy policy on a much sounder understanding of this limit than we now possess’; and, second, since the ‘problem of global effects of energy production, like….’
The amount of carbon dioxide in the air was roughly 330ppm. As of 2024 it is 422ppm, but check here for daily measures.
The context was that the United Nations Environment Programme had been going for a couple of years, since the Stockholm conference. Science had been publishing articles, Weinberg had been paying attention. The modelling conference had just finished in Sweden. Weinberg as a big fan of nuclear thought that this was another selling point for nuclear – that its carbon emissions were so much lower.
What we learn why it matters is that the pro nuclear gloss on climate mitigation has been around for a long time. Weinberg was a serious player.
What happened next? Well, in 1979, Weinberg visited Australia and gave a speech which got reported in the Canberra Times and so forth. It explicitly mentioned nuclear as a climate solution. And again, that puts into context; what I thought was unusual in 1981 of the various Liberal and Country Party Senators talking about it was not that big a deal. People knew by the early 1980s, people knew who were paying any real attention.
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.
