While the mitigation of climate change is typically framed as a problem globally, the literary genre of climate fiction (cli-fi) plays an indispensable role in shaping the cultural and psychological conditions necessary for collective action. Climate fiction addresses the issue by transforming abstract statistics and distant future projections into tangible, emotionally resonant human experiences. First, cli-fi serves as a "prosthetic imagination," allowing readers to inhabit the lived realities of a warming planet thereby breaking through the psychological barriers of temporal and spatial distance that often paralyse action. By providing concrete sensory details and character-driven plots, these narratives make the "hyperobject" of climate change comprehensible and personally relevant. Thus, the paper is an attempt to examine how climate fiction functions as a repository for future memory and a workshop for social resilience. Unlike purely apocalyptic narratives that can induce fatalistic despair, the most effective works of climate fiction model adaptive strategies, reimagine community structures and explore the ethical dilemmas of mitigation and justice. They offer speculative spaces where readers can confront the emotional weight of loss while simultaneously envisioning pathways toward survivable and even thriving futures. This process of pre-traumatic growth and narrative forecasting is crucial for building the psychological stamina required for long-term civic engagement. Cli-fi shape the perceptual frameworks through which society interprets the world with positive impacts. In a culture saturated with misinformation and short-term thinking, climate fiction provides a counter-narrative that centres long-term responsibility and interconnectedness. To conclude, mitigating climate change requires not only technological innovation but also a transformation of the human imagination. By bridging the divide between knowing and feeling, climate fiction cultivates the moral urgency and collective will needed to translate awareness into action, positioning narrative as an essential, though often overlooked, tool in the global effort to stabilize the planet’s climate.
