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?

Pearce – “The Week the Climate Changed” New Scientist

[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…

July 29, 1974 – the World (will be heating) according to GARP

On this day, July 29 1974 a World Meteorological Organisation conference on climate modelling began, running until 10 August. 

As Bert Bolin (one of THE key figures) wrote in the foreword-

At the United Nations Conference on the Human Environment held in Stockholm in June 1972, it was emphasized that the earth’s climate is of basic importance to man and his well-being. Climatic variability and possible change are still essentially unpredictable although they are significant factors in the continued development of both industrialized and developing countries. Some of the most important problems that confront us were very well summarized in the SMIC report “Study of Man’s Impact on Climate”, (1) which was available at the UN conference and served as an important reference document. In recommendation 79d of the conference, it was recommended that the World Meteorological Organization (WMO) in co-operation with the International Council of Scientific Unions (ICSU) “continue to carry out the GARP (Global Atmospheric Research Programme) to better understand the general circulation of the atmosphere, the causes of climatic change and whether these causes are natural or the result of man’s activities”.

At its eighth session in London in March 1973, the JOC considered in detail the role of GARP for studies of climate and its fluctuations. It was proposed that the next step towards an active programme would be the organization of an International Study Conference on the Physical Basis of Climate and Climate Modelling….

The conference was held at Wijk outside Stockholm during the period 29 July to 10 August 1974 with a total attendance of about 70 scientists from different parts of the world. Their devoted work during two weeks has resulted in the present report.

Why this matters. 

These were the building blocks – between 1970 and 1975 – when climate scientists patiently assembled the evidence, debated, refined. By about 1976/7 it was pretty clear what was coming, just a question of when (how fast, in what order). They did try to warn the politicians. And some of the politicians kinda sorta listened a bit.

What happened next?

The scientists kept at it. (Impact) Science is very very cool.. Some joined the dots, understood the implications, quicker than others. By 1979 the smarter ones were getting quite nervous….

UPDATE 3 July 2024. See this 1995 interview with CC Warren.

WMO started already in the 1970’s to concentrate more than before on climate problems. An Executive Committee panel on Climate Change was established in 1975, with Dr. Bill Gibbs from Australia as Chairman, and CCL, under the chairmanship of Helmut Landsberg, from 1973, re-oriented its effort towards environmental problems related to climate. About the same time, in 1974, the Global Atmospheric Research Program had a meeting in Stockholm in order to agree on which problems related to climate that should be of main interest to this program in the next few years. In fact the meeting discussed the fundamental question to change the classical approach to climate studies from the statistical one towards a more physically-oriented one. In fact in the Stockholm Conference on the Physics of Climate in 1974, the numerical forecasting modelers who had worked for about ten years or more on modeling the general circulation of the atmosphere were now interested in trying to apply similar mathematical approaches to the global circulation of the atmosphere and to other aspects of understanding of the future climate. It would then be possible to clarify what could be expected to happen on the globe, if the increase of the carbon dioxide from human emissions from burning fossil fuel would continue without change.
The Global Atmospheric Research Program, when it had been accepted by the U.N. in 1962, included a proposal for a program divided into two parts: one on the experiment to improve the weather forecasting on the basis of increased observations around the globe. This experiment, proposed for about ten years by Bo Doos in WMO, had in 1974, reached a stage where it could be expected to take place within the next five years. For that reason, Dr. Bert Bolin, who was in charge of the Global Atmospheric Research Program, thought that it was timely to start with the second part of the GARP program, namely the climate part. This was the basic reason why the Conference in Stockholm in 1974 was called and the physical foundations of climate were established.

June 14, 1979 – the messy inclusion of climate change in energy politics

Below is a brilliant guest post, by Swedish historian Kristoffer Ekberg. If there are other folks out there who want to write guest posts – please do get in touch! drmarchudson@gmail.com

14 June 1979 and the messy inclusion of climate change in energy politics

Kristoffer Ekberg

On this date, 14 June 1979,  the Swedish government gave the state-owned utility Statens Vattenfallsverk AB or short Vattenfall (meaning water fall) the task of  undertaking a large scale investigation into ways of introducing more coal into the energy mix without harming the environment or the health of the population, Kol-Hälsa-Miljö (Coal-Health-Environment).

The aim was to increase the use of coal. The task might not seem strange given the fear of volatile oil prices during the 1970s and the fact that in the beginning of the 1970s up to 75% of Sweden’s energy consumption came from imported oil. Transitioning to a source of energy that was seen as more secure due to the possibility to source it from the proximity in northern Germany seems like a rational choice when only looking at this development.

But understanding this as a strategic move based on solely energy security shows only part of the picture and obscures the dubious enterprise, given the already-existing knowledge of climate change present among the political elites.

Famously hosting the first UN meeting on the human environment in 1972 the issue of climate change was already present among the leadership of the Social democratic party and Swedish political leadership. Bert Bolin (who would later become the first chairman of IPCC), had the year before also convened with the world’s leading climate scientists in Sweden.

In 1974 the Swedish prime minister Olof Palme publicly stated that climate change was one of the most pressing issues in the period up to the year 2000. In 1975 climate change was mentioned in the energy plan that would guide Sweden’s actions the coming years, clearly influenced by Bolin’s work. Climate change science was not unanimous but the Swedish leadership nonetheless engaged with the threat.

In these years, climate change became a useful argument for a Social Democratic leadership wanting to push for nuclear power. As opposition to nuclear grew larger and more forceful every year, partly resulting in the loss in the election of 1976 ending a 40 year period in power, nuclear became a problem but so was oil.

In governmental reports in 1978, climate change, which had initially been framed as a concern in relation to national energy production and consumption became associated solely with future threats on a global scale.

Even though the coal investigation was tasked with incorporating all available knowledge, the issue of climate change and CO2 was in most parts excluded, despite the previous reports from Bolin and others. Further, during the investigation the issue of CO2 came to the fore through trips to – for example – the Department on Energy, in the US but was deemed a problem not for Sweden but for high emitters like USA, Soviet Union and China.

When finished in 1983, the report mentioned climate change but these formulations were critiqued by the Swedish Meteorological and Hydrological Institute (SMHI) arguing that the investigation had failed to account for the impact on CO2 emissions from introducing more coal.

Why this matters

The episode told here speaks to the messy ways in which climate change entered discussions and speaks to the different strategies that have been used to keep climate change of the table in periods when energy issues are highly debated. The construction of delaying arguments is not new in contemporary society but is something that has happened constantly since climate change entered on the political arena.
