This chapter argues that the climate emergency, as a characteristic of the Anthropocene, is one of our most far-reaching and increasingly urgent man-made issues. At this time, therefore, we have moved beyond disaster, which supposes some element of externality and rescue, to an all-encompassing global catastrophe. To explore what this increase in order of magnitude from the local to the global means for notions of witness in the Anthropocene, I examine three collections based on first-hand research trips. I also engage with ecophilosophical considerations drawn from Timothy Morton’s Object-Oriented Ontology. The three collections, which focus on glacier and Arctic ice-cap melt as key indicators of the climate emergency, are Nick Drake’s The Farewell Glacier, Helen Mort’s The Singing Glacier and Nancy Campbell’s Disko Bay. Through them, an exploration into the poetics of the Anthropocene and how the poets navigate deep time, silence, extinction, and the nonhuman is undertaken. The question of what the future might hold is also posed as we look forward towards the existentially precipitous time horizons of the Anthropocene.
