Cabot office weekly roundup – 7 September 2012

Neville Gabie
Poor Neville Gabie, our Artist in Residence, has had a bad week with technology with his laptop and video camera breaking down.  Neville is currently recording and editing interviews of Cabot members for his project Common Room.  If you would like to get involved (Neville has a replacement camera now!), please contact cabot-enquiries@bristol.ac.uk or take a look at Neville’s web page.


Dave Kilbey
We have been working on the first edition of our new annual magazine this week.  We met with Dirty Design who are designing the layout of the magazine.  There is a lot of work to do between now and getting it printed in October so the next few weeks will be pretty hectic in the Cabot Office.

On Tuesday we met with Dave Kilbey who is project manager in IT Services.  He has developed a new mobile app called Nature Tracker to record invasive species in the UK.   Check it out.

Our top Cabot news stories in the last week or so are:
 New book published on Understanding the Earth System
 Non-equilibrium quantum states in atmospheric chemistry 
Cabot researcher highlights potential methane reservoirs beneath Antarctica 
Cabot Institute Internship in Energy Research

Converting probabilities between time-intervals

By
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

By
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

By
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 ...
