This paper examines the relationship between the sublime and the Anthropocene, the period in earth’s geological history characterized by human impact upon the planet. As the genre of Anthropocene fiction, or climate fiction, has emerged in recent years, difficulties in defining the new genre as well as identifying useful tropes and forms within cli-fi novels has given rise to several proposed methods of understanding the Anthropocene. This essay examines the problems posed within Anthropocene fiction as well as the history of the concept of the sublime before examining Jeff VanderMeer’s Annihilation to find evidence of the relevance of the sublime within the Anthropocene.
