In this article, we reflect on the work of contemporary Brazilian indigenous artists and philosophers who have developed an Amerindian critique of the Anthropocene and the climate emergency. Based on research co-produced by the Another Sky research project, poetry, performance, and orality are discussed as routes of an emergent epistemological turn in the face of the inevitable challenges that lie ahead. Through indigenous thought expressed in aesthetic manifestations, we discuss critical analysis of the current situation, as well as imaginaries of future social and ecological conditions needed for climate justice, epistemiological justice, and protection of life in the broadest sense.
