Communicating Climate Change Data: What Is the Right Format to Change People’s Behaviour?

This study looks at a comparison of three data formats for the communication of climate change information; a dynamic visual representation, tables and charts, and pictures. Using design principles which are largely drawn from the field of cognitive ergonomics, good examples of each data format that represented a local climate change issue were identified. A sample of 453 students was randomly assigned to one of the three data format conditions and compared on their understanding and comprehension of the data format information and their motivation to act to mitigate the effects of climate change. Results suggest that there was no clear “best” data format, although tables and charts were likely to have the most consistently positive impact. These results are discussed in the context of climate change communication.
