Thirty four years ago, on this day, October 18th, 1991,
Fred Singer The Greenhouse Effect and Global Warming: Fact or Fiction? Tasman Institute Seminar
Not his first rodeo…

The amount of carbon dioxide in the air was 355ppm. As of 2025, when this post was published, it is 425ppm. 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 was that carbon dioxide build-up had broken through as an issue in 1988. By 1989 the George C Marshall Institute (set up to shill for Reagan’s Star Wars bullshit) had entered the fray and was enabling denialist efforts, alongside the Global Climate Coalition etc. Australia was one market for its shite.
Singer – Singer had been a semi-respected scientist and bureaucrat from the 1950s onward. But at some point he had jumped the shark. Here, he was fresh from warping the words of a dying Roger Revelle, who had known that many people did not think Singer was much of a scientist…
The specific context was that the Ecologically Sustainable Development process was coming to an end and the moment of maximum danger – where the government might actually take on some of its recommendations – was about now. If you were going to bring out some idiot not very good scientist (as per Roger Revelle) now would be a good time. And so it came to pass…
What I think we can learn from this – evil people aren’t necessarily stupid or incompetent. (And conversely, the “good” guys aren’t all smart and competent.)
What happened next – The ESD got thrown in the bin by Paul Keating, who toppled Australian Prime Minister Bob Hawke a couple of months later. The Tasman Institute kept up with the tours, economic modelling etc.
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.
