The climate crisis is a highly complex phenomenon. Climate Assemblies face the challenge of how to present this complexity to members. Through systematic reviews and targeted interviews, this research brief considers three issues. First, the implications of the different tasks or questions that Climate Assemblies tackle. Tasks can be broad, cutting across the range of policy areas touched by climate change, or more focused on particular areas of climate policy and action. Second, the briefing considers the ways in which information about climate change is framed to assembly members. The third focus is on the implications of different modes of delivery. The briefing reflects on the choices made by previous Climate Assemblies, drawing on insights on climate communication.
