This handbook is for anyone who wants to have constructive day-to-day conversations about the climate crisis. It provides pragmatic and evidence-based guidance on how to talk about climate change with friends and family, acquaintances and strangers - on the bus, at work, at a sports event or at home over dinner. The handbook is informed by the idea that you don’t have to be a scientist, or live in a certain place, to care about and want to talk about climate change. It is a topic for everybody, whoever and wherever we are.
