<p>Around the world, young people are concerned about climate change, but some are also mobilizing to address the challenge. How do those young people collectively navigate these worries while taking climate action? Drawing primarily on ethnographic data, this article investigates the relationship between the stories young climate activists tell and the activists’ emotion culture of cultivated hope. In the emotion culture of cultivated hope, which structures expectations around emotional expression, activists first acknowledge shared feelings of anger, fear, and sadness and then transition to an emphasis on the ways collective action is an important generator of hope.
