Abstract Scholars have noted several connections between the COVID‐19 pandemic and the climate crisis, ranging from the material influence of the pandemic on climate change processes (e.g., how lockdowns temporarily lowered climate emissions) to the similar ways the crises have been managed. Both crises are also global in scope, have exerted a significant toll on human lives and require major changes in our lifestyles. However, while collective responses to COVID‐19 were rapid and concerted, efforts to address climate change continue to be met with resistance. In this article, we investigate the social vulnerabilities common to both crises and the lessons that policymakers in the climate field can take away from the pandemic. After outlining the theoretical and empirical similarities between the two crises, we present a general framework and recommendations for the use of social science‐based interventions. We focus on two broad topics of contemporary interest that lay bare social vulnerabilities of the coronavirus pandemic—conspiracy theories and racial and ethnic inequities—to highlight the ways that understanding social and psychological processes associated with the pandemic can help inform more efficient climate policies. Public Significance Statement This paper shows how the COVID‐19 pandemic's social and psychological lessons can guide climate change policies. By leveraging social science insights, we propose strategies and illustrations to combat misinformation and address social inequities, ultimately fostering more effective and inclusive climate actions and benefiting policymakers and society at large.
