How should IR deal with the "end of the world"? Existential anxieties and possibilities in the Anthropocene.

The Anthropocene, a proposed new geological age marking the planetary impact of humanity, is no longer a newcomer to the field of International Relations (IR). Several scholars have recognised the value, as well as the danger, of the Anthropocene for theorising international relations. This article focuses on the existentialist questions and ideas derived from IR's engagement with the Anthropocene, particularly on the anxieties surrounding the extinction of the human species, the meaning of the Anthropos, and humanity's planetary stewardship. By drawing on scholarly discourses on these physical, spiritual, and moral anxieties, I argue that existentialist thinking helps expose IR's anthropocentric, universalist, and hubristic tendencies, which are also prevalent in the broader Anthropocene discourse. It also serves as a reminder of the freedom to explore possibilities, albeit with a lack of certainty, for reimagining the place of humanity and IR as a discipline in this new geological age. Therefore, existentialism reveals IR's dissonance with the paradoxes and uncertainties that the Anthropocene brings while offering a path toward theorising the "end of the world".
