The aim of this chapter is to analyze how the principle of hope in Ernst Bloch¿s theoretical proposal turns out to be a useful philosophical reference when designing mitigation and adaptation proposals in the face of the climate change crisis. The method followed in this chapter is based on analogical hermeneutics (Beuchot, Tratado de hermenéutica analógica. Editorial Ítaca, FFyL, UNAM, México City, 1997) in order to study an interpretation of a philosophical proposal about the problem of climate change. The hypothesis put forward is that proposals for mitigation and adaptation that seek to respond to the climate change crisis must be centered on the ontology of the not-yet-being; it is a reality in the process of being, which anticipates the full reality. The chapter proposes a dialectic discourse between adaptation mitigation strategies and the problem of climate change, as a moving process that builds new realities through human intervention; therefore, the horizon marks the way, recovering the value of the Principle of Hope and Utopia for orienting humanity.
