Fisheries and climate change stall at Big Green Week

Gurnard - a relatively sustainable fish

Steve Simpson

Steve Simpson talking to passers-by

A brilliant (and breezy!) time was had by us at Big Green Week on Saturday 9 June 2012. Apart from our umbrella blowing over in the wind and collapsing the whole stand, we made a quick recovery and had a very successful day.

We had our marine biologist, Steve Simpson, on hand to talk to people about sustainable fish and how climate change is affecting what fish we should eat.

Big and little kids got involved by catching a fish from our small sea and finding out about and seeing the real fish from the seas around Britain.

The MCS Good Fish Guides about what fish to eat were very popular, as was the Fish Fight sign-up sheet from Hugh Fearnley-Whittingstall's campaign to end the wasting of by-catch.

We also had MSC certified fish products on show to let people know what to look out for when buying from the shops.

Here are some pictures from the day.

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

Cabot office weekly roundup – 20 July 2012

Herbert Huppert This week we have been holding our Cabot Summer School on risk and uncertainty in natural hazards . The week has gone very well and I have received some very positive comments from attendees. We had some fantastic speakers including Herbert Huppert, Jonty Rougier, Steve Sparks, Willy Aspinall, Li Chen, Tamsin Edwards, Philippa Bayley and Thorsten Wagener. Cabot would like to say a great big thank you to all of you for making the Cabot Summer School such a success. We’re very much looking forward to next year. Paul F. Hoffman This week, Cabot member Rich Pancost secured Paul F. Hoffman of Snowball Earth fame as the next Science Faculty Colloquium speaker in September. I saw the new templates for our website today. Its all looking good and I’m quite excited about the implementation of its new look. By the end of the summer I hope to have it all up and running. We would like to congratulate Cabot member Professor Mark Eisler and

Discussing Rio+20 at the House of Lords

Last month I went to the House of Lords for a meeting of the All party group for international development and the environment. The morning’s question was: Where next for sustainable development after Rio+20? I’ll give a brief resume of who said what, with some of my thoughts following over the next weeks.... Joan Walley , MP for Stoke-on-Trent North opened the morning's reflections on Rio. She chairs the Environmental Audit Committee which monitors action across different government departments. At the top level, Rio lacked vision and clear objectives. Her select committee really tried to engage with government, but there was no commitment from the PM that he was going, and no clear vision from them. She felt the process needs to be reinvigorated - connecting, collaborating, and understanding the details - e.g. how the proposed Sustainable Development Goals will link with the Millennium Development Goals. Stephen Hale from Oxfam asked how do we accelerate the p
