Forty-six years ago, on this day, November 21st, 1978, people in Sydney got a news broadcast about Trouble Ahead…
The amount of carbon dioxide in the air was roughly 335ppm. As of 2024 it is 423ppm, but check here for daily measures.
The context was that the CSIRO had started to make serious noises about CO2. There’d been a documentary called A Change of Climate in 1976. There’d been, more importantly for these purposes, a conference being held on Phillip Island in Victoria. That was CSIRO Australian Academy of Science and someone else. And so it was a nice little hook for the journo, alongside some modelling work released.
What we learned is that by 1978, the carbon dioxide issue was being explained to people in Sydney. Whether they were paying much attention or not, is another question.
What happened next? CO2 kept appearing in the newspapers with perhaps a little bit more frequency. In 1980 the Canberra Times covered the conference hosted by the Australian Academy of Science. In 1983, the Australian covered the EPA’s report. But it wasn’t really till 1986/87/88 (especially ‘88) that the issue started getting serious traction. Meanwhile, the emissions kept climbing.
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.
