This article considers the role of the public humanities in fostering conversations about climate science and policy through a transdisciplinary performance at the University at Buffalo in New York. The Great Lakes Climate Theatre Initiative is a new project that brings together sustainability scientists with theater practitioners to create new and mixed methods for climate preparedness that are both inclusive and impactful. Toward a Climate Haven was the first project conducted by the initiative with the goal of exploring how Buffalo might become a safe and equitable destination for climate migrants. This first project resulted in a public event that combined the performance of a newly-commissioned play, a talkback session, readings from a local youth writing workshop, and a presentation from a local county official. In this article, our team reflects on how we brought these various threads together to leverage the public humanities in the effort to prepare for climate change.
