Building public support for ambitious climate policy requires understanding what shapes people’s attitudes toward climate change and how they respond to different ways of communicating the issue. My research in this area examines the effectiveness of framing strategies — whether reframing climate policy around co-benefits like jobs or health can increase support — and finds that the evidence is more nuanced than commonly assumed. This work also investigates the measurement of climate scepticism, showing that social desirability bias leads surveys to underestimate its prevalence, and examines how economic shocks like the COVID-19 pandemic can erode environmental concern. A systematic meta-analysis of over 120 framing experiments reveals important methodological challenges in the literature, including publication bias and omitted interaction effects.
