The climate crisis is an enormous challenge for contemporary societies. Yet, public discussions on it often lead to anger, mocking, denial and other defensive behaviours, one prominent example of which is the reception met by the climate advocate Greta Thunberg. The paper approaches this curious phenomenon via shame. It argues that the very idea of anthropogenic climate change invites feelings of human failure and thereby may also entice shame. The notion of “climate shame” is introduced and distinguished from “climate guilt”. Whereas climate guilt prioritises the flourishing of the environment and is focused on actions and morality, climate shame is concerned with human identity and selfhood. The paper then explores whether shame is a morally destructive or constructive emotion. Making use of both psychological and philosophical literature on shame, it argues that although shame faces many challenges that question its usefulness in moral pedagogy, these challenges can be met with “moral maturity”—moreover, following a utilitarian approach, the overall benefits of climate shame can justify its costs to individuals. My argument is that climate shame holds the potential of being a highly effective moral psychological method of persuasion, capable of inviting wholesale critical reflection on current, environmentally damaging practices and cultivation of more virtuous ways of co-existing with the rest of the natural world and other species.
