At the Natural History Museum of Utah, A Climate of Hope (ACoH) offers a path to rational hope. This exhibit shows how climate change affects Utah's people and places, while also helping visitors envision a healthy, prosperous, low-carbon future. In this session, exhibit developers and learning researchers share stories of ACoH, from prototyping to research-based iteration that continues today. Audience members will participate in activities to collectively imagine new ways of supporting visitor learning towards constructive hope amid climate change.
