The Uncertain World: Is uncertainty used as a stick with which to beat climate change?

The Cabot Institute is focussing on our Uncertain World this year, with a host of events to meet with new communities, think around new ideas and establish new solutions for what’s in store for us in the future.  We are posting blogs during November on 'Our Uncertain World'. Join the conversation with us on Twitter using the hashtag #UncertainWorld and contribute your thoughts and concerns to our (virtual) graffiti wall.  Read other blogs in the series by visiting the weblinks at the bottom of this blog.

Uncertainty runs through climate science like the lettering in a stick of rock. It will never 'go away' and no communication strategy should ever aim for this. But it does seem as if somehow, uncertainty has become a stick with which to beat climate change in a way that it has not for other areas of science (or perhaps more to the point, in other areas of life). So it is worth asking why this is the case, and what we can do to address this...

My background is in psychology, and there is a rich literature on the psychology of risks perceptions that is certainly relevant to communicating uncertainty in the context of climate change. We know that people discount certain risks and inflate others, given the chance many will lean towards 'wishful thinking' rather than a cold, rational assessment of the probabilities.

But to my mind, the challenge of communicating uncertainty in climate change goes beyond presenting information in a way that will 'beat the biases' of the human mind - although there is an important role for this. To me it is more about 'going with the grain' of public engagement with climate change, starting from 'where people are' and working backwards from there, rather than starting with the science...and this tends to be the approach we take at Climate Outreach, the organisation I work for

For example, its now well-established that some of the most important and consistent drivers of public engagement with climate risks are peoples values, worldviews and political orientation. Scepticism is essentially unjustified levels of uncertainty about climate risks...but what drives this perception is people's ideas about the implications of climate risks for their lives. People work backwards from an outcome that they don't like the sound of, or feel threatened by, and assess the underlying risks accordingly. So starting with those 'implications' is crucial, and why the focus of the second day of the Cabot Institute's Uncertain World conference is so important.

Where will people live? What impact is climate change having on Civil Society and the voluntary sector? These are crucial questions covered in Day 2, and help to join the dots between the underlying science and the 'social reality'  of climate change for non-scientists and specialists. Once people are more engaged with 'solutions' to climate change that they endorse or can identify with - when people hear a story about climate change that sounds like it was written about them - they are much more likely to be open to the science that defines and describes the underlying problem.

My sense is that the biggest step we could take (as a community of people from very different background and disciplinary perspectives) would be to develop much greater strategic capacity to 'join the dots' between the science and the stories that people engage with. At the moment, sustained public engagement with climate change does not happen in a co-ordinated way, but events like the Uncertainty Summit are important ways of bridging the gap between different disciplines and professions. If the expertise and diversity of perspectives represented at this meeting could be marshalled on a permanent basis, to provide a new type of institution explicitly tasked with full-time public engagement on climate change (from the science through to the social reality of the issue), we would have a level of public engagement proportionate to the scale of the challenge we face.

Converting probabilities between time-intervals

This is the first in an irregular sequence of snippets about some of the slightly more technical aspects of uncertainty and risk assessment.  If you have a slightly more technical question, then please email me and I will try to answer it with a snippet. Suppose that an event has a probability of 0.015 (or 1.5%) of happening at least once in the next five years. Then the probability of the event happening at least once in the next year is 0.015 / 5 = 0.003 (or 0.3%), and the probability of it happening at least once in the next 20 years is 0.015 * 4 = 0.06 (or 6%). Here is the rule for scaling probabilities to different time intervals: if both probabilities (the original one and the new one) are no larger than 0.1 (or 10%), then simply multiply the original probability by the ratio of the new time-interval to the original time-interval, to find the new probability. This rule is an approximation which breaks down if either of the probabilities is greater than 0.1. For exa...

1-in-200 year events

You often read or hear references to the ‘1-in-200 year event’, or ‘200-year event’, or ‘event with a return period of 200 years’. Other popular horizons are 1-in-30 years and 1-in-10,000 years. This term applies to hazards which can occur over a range of magnitudes, like volcanic eruptions, earthquakes, tsunamis, space weather, and various hydro-meteorological hazards like floods, storms, hot or cold spells, and droughts. ‘1-in-200 years’ refers to a particular magnitude. In floods this might be represented as a contour on a map, showing an area that is inundated. If this contour is labelled as ‘1-in-200 years’ this means that the current rate of floods at least as large as this is 1/200 /yr, or 0.005 /yr. So if your house is inside the contour, there is currently a 0.005 (0.5%) chance of being flooded in the next year, and a 0.025 (2.5%) chance of being flooded in the next five years. The general definition is this: ‘1-in-200 year magnitude is x’ = ‘the current rate for eve...

Your Waste of Time: Art-Based Geographical Practices and the Environment

This blog post thinks through the themes of aesthetic interventions, sensing time and engendering response-ability using artistic responses to climate change. Here, these themes are drawn from one piece of art, Your Waste of Time, by Danish-Icelandic artist Olafur Eliasson. This performative showcasing of glacial ice establishes interactions and relations between human bodies and icy materialities- but what is at stake here and what potentialities could be created through artistic practices? These are questions that have arisen through my current dissertation, where I hope to explore artistic responses to environmental degradation through the materialities of ice and plastic. For the piece Your Waste of Time, Danish-Icelandic artist Olafur Eliasson transported several large blocks of ice from Vatnajökull, the largest and oldest glacier in Iceland, to the Berlin gallery Neugerriemschneider (Eliasson, 2006). This glacier is almost incomprehensibly ancient, with some parts dating fro...
