The current ecological crisis is the single most pressing problem for utopian projects today. The ever-expanding intersections of technology and capital in the Age of the Anthropocene are, if nothing else, invitations to consider the possibilities for utopian thought particularly as it is embodied in the formal structures of science fiction (sf). Science fiction is a genre whose origins in post-Enlightenment industrial modernity align it with globalization’s valorization of the scientific progress and limitless economic expansion that have contributed so much to the shape of the current crisis. This introduces a significant tension into science fiction’s efforts to imagine a way out of the crisis and toward some kind of utopian future that is not simply a repetition of the present. In the context of today’s climate crisis, what are the possibilities for utopian thought that succumbs neither to the anxieties that arise in the face of inevitable and radical change nor to an optimistic “techno-utopianism” that threatens to repeat all the errors of the past? What are the possibilities for utopian thought that takes account of human beings as an inter-relational species deeply imbricated with all life on Earth? I look at a variety of twenty-first-century Anglo-American sf stories through the lens of eco-philosopher Timothy Morton’s theory of climate change as a “hyperobject” and in the framework of sf writer Geoff Ryman’s “Mundane Manifesto” (2004)—his call for a kind of science fiction that recognizes the Earth as the only home that can sustain us.
