This chapter starts with an analysis of the psychological features of climate change that make it difficult to address from a human perspective. This includes discussing the dissociation of causes and effects in time and space, the non-linearity of the effects in complex systems where many factors interact and the symptoms of climate change that appear within weather events people are used to. Based on this mapping of the psychological challenges of climate change communication, the stage model of self-regulated behavioural change (a stage-based behavioural change framework) is introduced, with its implications for communication strategies outlined. Classic communication techniques for changing people’s climate change-related behaviour are then presented and evaluated in the context of this model, followed by coverage of more innovative communication techniques, such as artwork, music, games and so on. The last section of the chapter introduces the concept of disruptive climate communication and contrasts it with more subtle communication forms such as nudging.
