The search for decisive actions to remain below 1.5 °C of global temperature rise will require profound cultural transformations. Yet our knowledge of how to promote and bring about such deep transformative changes in the minds and behaviours of individuals and societies is still limited. As climate change unravels and the planet becomes increasingly connected, societies will need to articulate a shared purpose that is both engaging and respectful of cultural diversity. Thus, there is a growing need to ‘raise the temperature’ of integration between multiple ways of knowing climate change. We have reviewed a range of literatures and synthesized them in order to draw out the perceived role of the arts in fostering climate transformations. Our analysis of climate-related art projects and initiatives shows increased engagement in recent years, particularly with the narrative, visual and performing arts. The arts are moving beyond raising awareness and entering the terrain of interdisciplinarity and knowledge co-creation. We conclude that climate-arts can contribute positively in fostering the imagination and emotional predisposition for the development and implementation of the transformations necessary to address the 1.5 °C challenge.
