A large literature is proliferating on capitalism's role in driving climate breakdown. In this literature, capitalism is seen as the endless pursuit of growth, under which nature and its finite resources are exploited for profit. The climate crisis is the result of these processes. However, capitalism alone cannot explain the racial inequities produced by climate disruption, nor can it account for the disproportionately large contributions of Global North countries toward this crisis. In this article, I develop a Du Boisian approach to the climate crisis, showing how his conception of racial and colonial capitalism can develop our understanding of the causes, dimensions, and effects of the climate crisis. I explain how a Du Boisian approach furthers our understanding of racial and global inequalities in the development and impacts of global warming and in the production of fossil fuels, as well as how racism can shape climate inaction. Finally, I name some limitations of Du Bois' theory and elaborate on how a contemporary, decolonizing approach to the climate crisis might address these.
