October 15, 1985 – Villach meeting supercharges greenhouse concerns…

On this day, October 15 in 1985, scientists from around the world began a meeting that would lead to the final arrival of the climate “issue” on the international agenda.  Here is the beginning of an article by prominent science writer Fred Pearce, writing in 2005…

“The week the climate changed; Villach, a sleepy spa town in southern Austria, is not an obvious place from which to change the world. But 20 years ago this week, a conference there became the spark that lit today’s burning concern about global warming. Before Villach, the greenhouse effect was a subject for specialised physicists – a possible problem for future generations and nothing more. After Villach, global warming swiftly became the world’s top environmental story. The conference, say the people who were there, was the catalyst for the formation of the UN’s Intergovernmental Panel on Climate Change (IPCC) – the gatekeeper for the science of climate change – and led to the Kyoto protocol. So what happened? Was it atmospheric chemistry or personal chemistry?

[The amount of carbon dioxide in the atmosphere was 343.35ppm. At time of writing it was 421ishppm- but for what it is now,well, see here for the latest.]

The context was this – since the early 1970s there had been international meetings of scientists to look at Man’s Impact on the Climate/Environment, in various places (Williamstown, Wijk, Norwich, Villach). From 1972 some of these meetings had been co-sponsored by the UN Environment Program, alongside the World Meteorological Organisation. The models got better, the scientists got surer of what was happening, what might happen…

The Villach 1985 meeting is the one at which the non-carbon-dioxide greenhouse gases got properly added up, and they realised trouble was afoot, less hypothetically and sooner than they’d been thinking…

Why this matters. 

History is good, isn’t it? If you didn’t think that, you’d not be reading this site.

What happened next?

American senators got the message – in December we’ll talk about Carl Sagan’s testimony in December 1985.  The US Department of State, nervous about being bounced into binding international action on carbon dioxide the way they had been about ozone, decided to slow the whole thing down and make sure governments got to vet scientific statements…
