On 15-16 May 2014, the University of Exeter hosted an impressive array of climate change researchers from across the world. It was a medium-sized conference discussing the state of climate change research across all three working groups of the Intergovernmental Panel on Climate Change, along with goals and challenges for the future.
I found the meeting absolutely fascinating for all manner of reasons, most of which I hope to cover in two following blog posts. This post is something of an introduction.
One of the most obvious draws for me was that it brought together people from all three IPCC working groups. As a physical scientist I am familiar with the workings and results presented by the first working group, but the other two are rather more mysterious to me. This meeting served as a great summary. In case you’re not aware, the IPCC reports are produced by three separate groups:
- Working Group 1: The Science of Climate Change
- Working Group 2: Impacts, Adaptation and Vulnerability
- Working Group 3: Mitigation of Climate Change
These working groups operate rather separately. Once they have all released their reports they are combined in a synthesis report. The synthesis report for the Fifth Assessment goes to governments in October 2014. So, where next?
In the next two blog posts I’m going to discuss two themes which I felt ran through the conference.
The first is: how should we approach climate change? What kind of discussions should we be having, and how should they work? How should decisions be made?
The second is: what is the future of climate research? What information do we need and how can we get that information?
These questions are clearly inter-related. The first question is more of a political one, but the second one is clearly also politically relevant, as ultimately the choice of what information we need lies with policymakers and the public. This is one of the over-arching topics which transcended both of the themes: that climate research and policymaking is a mixture of facts and values. In simple terms: it is a fact that the planet has warmed, will continue to warm to a greater or lesser degree, and that this warming will have impacts. However, what we do about it (or indeed whether we do anything about it) is a question of values. It is a normative question in which there is no single right answer.
Even though facts might be seen as ‘valueless’, many of the speakers at the meeting argued there was no such thing. Asuncion St Clair quoted Bruno Latour: ‘no knowledge is neutral’. The way facts are presented requires the imposition of some kind of value system. Ottmar Edendorfer said at the conference that he sees the role of the IPCC as akin to that of a map-maker. The map-maker doesn’t tell the user which route to take. The map-maker examines the landscape and maps out the features, obstacles and characteristics of all paths. And yet the map-maker can’t just present the ‘facts’. The choice of what goes on the map depends on what the map-maker thinks the user needs. Take, for example, the difference between political and topographic maps. One presents largely artificial boundaries between nation-states; the other presents details of the landscape. Which one you choose would depend on your needs.
Even though it’s not possible to be completely neutral, then, perhaps the IPCC could try to address this problem by providing as much information as possible. Of course, this doesn’t make it very readable and that’s why there are two summaries that attempt to make the make points easier to grasp: the Summary for Policymakers (the content of which has to be agreed to by governments) and a Technical Summary (which doesn’t). But the choice of what goes in there might also be normative.
Given its stated goal to be ‘policy relevant, not policy prescriptive’, and the enormous complexity of its subject matter, the IPCC often makes very careful statements emphasising precisely what we do and do not know. Chris Field pointed out that this leads to something of a problem. He said that some of the statements turned out so vague that they were open to almost any interpretation. Different media outlets could make very different readings of the report and come to sometimes diametrically opposed conclusions!
This raises the issue of framings. ‘Framing is everything in this debate’ said Georgina Mace. What this means is that, given a more-or-less neutral presentation of information there is no single implication that naturally comes out. The implications of the findings of the IPCC depend on how one views the world. At the meeting Saffron O’Neill presented the results of some of her work on media framing of AR5. Common frames included: ‘settled science’, ‘unsettled science’, ‘security’ and ‘morality and ethics’. She pointed out that different frames implied very different policy options.
In the coming blog posts I hope to draw out some more detail on the two main areas of the conference: how should we approach climate change and what is the future of climate research? After all that talk of framings it’s important to say that these are my personal impressions, and not an objective report. If you want to find out exactly what went on at the meeting, you can catch up on the presentations and panel discussions on the website.
