Effective visual communication of climate change

, Steph Courtney and Karen McNeal explore the effects of improved data visualizations on user perception of climate change evidence.

In this study, the team redesigned three graphs from the Intergovernmental Panel on Climate Change Fifth Assessment Report. They assessed the impact of the redesign on graph usability and user perception of scientist trustworthiness and climate change risk, which correlate to both knowledge and intention to take action. The process was iterative, including two rounds of user testing and successive redesign and re-testing.

An interesting question explored in this study was whether more simplistic figures would look"less scientific" and thus less trustworthy. Surprisingly, this did not turn out to be the case."Pretty is fine," explains Courtney."If it looks nicer, it looks like you put time into it, so you care about it and you know what you are doing. Understandable and attractive graphs can be trustworthy.
