April 1, 1970 – “And on the Eighth Day” shown in Melbourne – including climate warning

Fifty four years ago, on this day, April 1st, 1970, a super documentary made in the UK is shown in the colonies…

Australian TV (Melbourne at least) showing And On the Eighth Day 1st April 1970 – see preview by TV critic at The Age From The Melbourne Age, 1st April 1970…

The amount of carbon dioxide in the air was roughly 325ppm. As of 2024 it is 425ppm, but check here for daily measures.

The context was that Australia, like the rest of the world, in the late 1960s, and especially in 1969, had really become aware of the environment problems. So a British (therefore prestigious) documentary about the issues was an obvious thing to buy, and to show.

What we learn is that there are these international networks of information. Of course there are. And people, good documentary filmmakers like Richard Broad. Their work got a big audience.

What happened next? Australia kept being informed by local scientists and filmmakers as well as international ones. And the climate issue was in the mix. In 1970-1972 – it was already there being spoken of as a serious potential problem. But we just couldn’t hold onto it as an issue. It’s too big, it’s too daunting, too all-encompassing for our species. And here we are, having failed to solve it for 50 years, by which time it becomes functionally insoluble.

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.

March 4, 1970 – American scientist vs ice age fears in Melbourne

Fifty four years ago, on this day, March 4th, 1970, a scientist talks about a human-induced Ice Age. Not likely, he finds.

I find that the present particulate loading would have to be increased by a factor of 5 to produce a 3°C drop in mean planetary surface temperature. This work was done in November and December of 1969 and was presented before the International Solar Energy Society in Melbourne, Australia, on 4 March 1970.

Earl W Barrett,, 1971 letter in Science

The amount of carbon dioxide in the air was roughly 324ppm. As of 2024 it is 425ppm, but check here for daily measures.

The context was that scientists, especially in America, were beginning to look seriously at carbon dioxide buildup at national conferences, starting to get findings. And scientists fancied an international jolly – sorry, “opportunity to network and further the advance of the human species’ knowledge.”

Australia was still in the dark ages on carbon dioxide buildup, it would be 1971-72 before scientists (Pearman, Pittock) started being paid to look at this stuff. Meanwhile, Melbourne was in the grip of its pollution fever. So Barrett’s comments will have free received interest in the media.

Also, in September 1969, the C02 issue had already been discussed by Australian scientists – in public fora.

What I think we can learn from this

“International networks of concerned scientists” etc. Science is international blah blah. But from the late 1960s, carbon dioxide was being looked at.

What happened next

In 1972 a clean air conference in Melbourne that had a specific set of papers about CO2 buildup. We ignored the scientists until 1988. Then we heard them but have basically ignored them since then.

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.
