Thirty four years ago, on this day, July 28th, 1990 UK science writer John Gribbin nails the problem.
AT WHAT POINT will politicians take real action to curb the emission of greenhouse gases into the atmosphere? A summary of the situation runs as follows: ‘Some blinkered optimists argue that until the case against carbon dioxide is proven, it is pointless to take any action to curb it. But since the only proof will be when the rains start to fail in North America and there is no spare grain to rush to famine regions, this hardly seems sensible.’
Gribbin, J. 1990. Talking Point: Why caution is wrong on global warming. New Scientist, 127 28 July, p. 18.
The amount of carbon dioxide in the air was roughly 354ppm. As of 2024 it is 426ppm, but check here for daily measures.
The context was that John Gribbin had been writing about climate systems as a trained physicist and science journalist for a good 15 years in New Scientist and so forth. He’d written various books and was well qualified to understand what the IPCC was saying in its various reports. By this time Working Group 1 had already reported and the synthesis report was due to happen.
There were by now outfits like the George C Marshall Institute, and World Coal Association trying to play denialist minimalizing games, and Gribbin was speaking out against taking their shit seriously.
What we learn is that by 1990, it was extremely obvious both that the world was going to warm and that denialists – for reasons of their own – would deny. The siren sounds of denial were to be warned against.
What happened next. Look around you. Who won? Who lost?
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.
