The COVID-19 pandemic and climate change cause enormous damage and pose huge governance challenges related to science-policy-public interactions. Due to scientific uncertainty and societal controversies, combined with demanding requests for transformation of technical systems and lifestyles, these problems are wicked, rendering conventional policies insufficient and laden with accidental impact. While much research has focused on each area, only few studies have aimed to learn from comparisons of similarities and differences in governance of the two crises, with their respective merits and shortcomings, in order to draw lessons for how to better cope with wicked problems. This project takes on that challenge and explores in particular a set of critical science-policy-public interactions. Based on in-depth interviews with key actors, the projects examine what lessons for governance can be drawn from the COVID-19 pandemic and applied to climate change. Main supervisor: Mikael Karlsson
