Book excerpt: This book describes a fresh approach to climate change communication: five core principles for public engagement that can propel climate change discourse out of the margins and into the mainstream. The question of how to communicate about climate change, and build public engagement in high-consuming, carbon-intensive Western nations, has occupied researchers, practitioners, and campaigners for more than two decades. During this time, limited progress has been made. Socially and culturally, climate change remains the preserve of a committed but narrow band of activists. Public engagement is stuck in second gear. By spanning the full width of the space between primary academic research and campaign strategies, this book will be relevant for academics, educators, campaigners, communicators and practitioners.
