My dissertation project, “Fossil Power: A Political Theory of Climate Change,” argues that in order to understand the politics of climate change — and how to solve it — we must understand how climate change has been made thinkable as a political problem: one caused by politics and power relations. The dissertation argues that when applied to the problem of climate change, different concepts of politics and power produce different visions of the causes and solutions of climate crisis. Drawing on Michel Foucault and Marxist state theory, I ultimately argue that we need a new grammar of power to make visible the power relations that reproduce climate change, proposing the concepts of fossil rationality, fossil governmentality, and fossil sovereignty as building blocks of this new grammar.
