From a purveyors perspective I want to stress the importance of first understanding the purpose that the client has. Purpose determines quality requirements. A large investment decision requires more specific information (including probabilities) than, for instance awareness raising. In the case of Heineken, the purpose was to raise a sense of urgency and to make climate change ‘tangible’ for non-experts. Therefore we decided to focus on making clear and simple visualizations, only showing the RCP45 and 85 maps and graphs. We left out further details on probability and uncertainty margins, and the information was used to facilitate ‘what if’ types of discussions. What if climate change continues in this direction?
