This course explores the relations among colonial history, contemporary conflicts, and climate change by examining the political, legal, epistemic, and aesthetic challenges this kind of violence initiates. Reading colonial and urban histories against meteorological and climate data, we use environmental modes of detection and imaging in order to reveal tropical forests to be archaeological resources in which patterns of human intervention and violence can be read. The Amazon is not only an ecological threshold, but also a political one, and it continues to bear the traces of the deadliest land conflicts in Brazil.
