Without caring for and acknowledging the deep traumas faced by those fighting in our social movements, we risk activists’ and the movement’s burnout. The climate justice movement is no different. The Climate Justice Coalition (CJC) of South Africa is a dynamic alliance of trade unions, youth, faith and community-based organisations, grassroots and independent activists, and international and local non-government organisations. This vibrant diversity underscores the complex and varied ways in which trauma can impact our members, thereby impacting the movement itself. Our chapter sheds light on how institutional betrayal can become a traumatic stressor in the lives of climate activists, especially activists who belong to communities which have been historically marginalised. To combat the overwhelming experiences of trauma, which manifest as paralysis, helplessness, and burnout within movements, we advocate for the practice of radical care, kinship, rest, and pleasure. This practice, when practised among activists and supported by community psychologists, can be a powerful tool in the fight against trauma. It can be a powerful tool in the quest to create lasting social movements which respond to the injustices of the world, merging and mutating to address the needs of the most vulnerable. Awareness and understanding of context is everything, and experience is the best teacher for understanding. Armchair practice in psychology in the context of the climate emergency will do little to enable good mental health for activists. We call upon psychologists to be allies or activists themselves in the fight for climate justice—after all, it is a fight for everyone’s future.
