The Uncertain World Summit from my perspective (without any uncertainty)

In October we held our Uncertain World Summit, with a host of events and interactions to meet with new communities, think around new ideas and establish new solutions for what’s in store for us in the future.  You can read the other blogs covered in 'Our Uncertain World' at the bottom of this blog. Join the conversation with us on Twitter using the hashtag #UncertainWorld and contribute your thoughts and concerns to our (virtual) graffiti wall.

(Note to the reader: I’d like to mention that, from this point forward, I shall try not to use the word ‘uncertainty’. Not because it isn't important to talk about, but because I didn't want this blog to be absorbed by recognising it. There were many things that came out of the Uncertain World Summit that I felt were rather certain and I’ll try to focus on those for a change).

The Uncertain World whiteboard - full of notes and ideas!
The two-day event was replete with bite sized chunks of climate science and policy making, washed down with group discussions and (at the end) Somerset wine.  The attendee list was a vibrant jumble of scientists, philosophers, policy makers and industry leaders gathered together to discuss climate change. To do justice to the wealth of talks would be impossible in a short blog; there were contributions from a range of sectors including health, defence and agriculture as well as from climate researchers on topics such as sea level rise and land use change. Instead of reporting on the presentations, I thought I would focus on some of the recurring themes I noted from the discussions.

The first discussion I want to chalk up on the blogging-blackboard is the issue of science falling into the void between the scientific community and policy makers. The chain of decisions that propels a scientific revelation out of the lab and into the lives of ordinary people is convoluted and confused. How can we expect the world to save itself when the world doesn't know what it needs saving from? The methodical production of scientific progress wrapped up in a safety blanket of statistical error is hard to chew on for the policy makers and even harder to digest by the general public. This became somewhat of a theme as I moved through the discussion groups (and now I see also in Adam Corner’s blog - it is clearly something that needs to be addressed at the base level).

The second issue to make it onto my summit-summary was how to best assimilate the objectives of climate change prevention into the everyday lives of the population. There was a unanimous resolution that, in order to elicit any modifications in people’s everyday routines, the impetus should be positive rather than negative: Employing threatening forecasts of apocalyptic temperature rise (however true they may be) simply isn't an effective motivation when the effects aren't yet tangible to the majority of the population. Instead, communicators should be painting the picture of the switch to green as a platform for economic growth facilitating more job prospects and greater social equality.

Reviving and utilising national (and international) pride is essential
to stimulating a universal response to climate change.
The mechanisms to power this change were harder to isolate. There was recognition that, in order to stimulate a universal response, reviving and utilising national (and international) pride is essential. The argument drew from examples of past regional and global cooperation particularly the World Wars and the first man on the moon. If, as occurred in these examples, a country unites with a mutual aim it can transcend social divisions to become a more efficient machine. Of course, the challenge lies in putting climate change prevention on a sufficiently glamorous pedestal as to evoke such a response. To achieve this there were a host of creative solutions including setting up community food schemes and mobilisation the Woman’s Institute to the cause.

More generally, the discussion wavered around the best ways to implement the outcomes of the discussion, whether through legislation or communication. In a problem so laden with political and economic bias it is unsurprising the current global responses are flavoured with self-interest. Overcoming this, in my opinion, will be the biggest challenge of all. On a brighter note, I found the summit an amazing experience that broadened my thinking on climate change. Despite the gloominess of the situation, I went away from the event feeling that problem-solving had triumphed over defeatism and that there are several paths we can take that can lead us towards a greener future. We just need to persuade everyone to take one.

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 example

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

Coconuts and climate change

Before pursuing an MSc in Climate Change Science and Policy at the University of Bristol, I completed my undergraduate studies in Environmental Science at the University of Colombo, Sri Lanka. During my final year I carried out a research project that explored the impact of extreme weather events on coconut productivity across the three climatic zones of Sri Lanka. A few months ago, I managed to get a paper published and I thought it would be a good idea to share my findings on this platform. Climate change and crop productivity  There has been a growing concern about the impact of extreme weather events on crop production across the globe, Sri Lanka being no exception. Coconut is becoming a rare commodity in the country, due to several reasons including the changing climate. The price hike in coconuts over the last few years is a good indication of how climate change is affecting coconut productivity across the country. Most coconut trees are no longer bearing fruits and thos
