This essay explores ways in which environmental educators might break with their existing traditions of research and pedagogy by critically appraising climate histories and anticipated futures depicted by SF (science/speculative fiction) in print and audio-visual media. SF has engaged the politics of climate change for at least two centuries and, as a form of public pedagogy accessible to all generations, provides alternative visualisations of the problems arising from humanity's destructive transformations of Earth's climate and possible ways of ameliorating them.
