This dissertation aims to investigate, from a philosophical point of view, how to cultivate the relationship between the making of science and the making of fiction can contribute to think about the planetary proportion of the ongoing ecological collapse. The research starts from the diagnosis that there is currently a disconnect between action and understanding, in other words, between the enormous energetic flux produced by the capitalist industrial civilization and the human capacity to dimension its catastrophic effects – not only for our species, but for a good part of the Earth s inhabitants. Thus, we can say that, for the warnings of climate science to make sense to everyone, that is, for us to learn to pay attention to the effects of anthropogenic actions, it is important that climate fiction make us feel, that is, that art invent stories that affect us to the point that we realize that, for planet Earth to continue habitable, it s necessary we build a healthy relationship with Gaia. This paper intends, therefore, to analyze the geopolitical implications caused by the ecological collapse, especially in the light of the oeuvre of Bruno Latour, but also from his dialogue with Dipesh Chakrabarty about the emergence of the Planetary, as well as from Margaret Atwood’s ustopian climate fiction, the MaddAddam trilogy.
