Blue-Action coordinated a series of webinars on climate science communication in 2020. These were aimed at early-career researchers, but anyone who wishes to engage people with their research at any stage will find them valuable. This webinar was delivered on 17th July 2020 by Will Harvey, who is a web and graphic designer at the Scottish Association for Marine Science. Will spent over a decade as a graphic designer in industry, before moving to academia. Here he shares insights into the process of designing infographics and key principles to create a design with impact.
