International Cli-Fi Day – April 20, 2025

International Cli-Fi Day is observed on April 20 every year. Cli-fi means climate change fiction. It is a genre separate from the science-fiction or speculative-fiction genre. We all know that our planet is suffering the consequences of global warming due to the release of carbon emissions. Some authors explore global climate change in their novels. There are a lot of films that deal with this topic and try to raise awareness about the dangerous consequences of climate change on our planet. It is of utmost importance that we change our current habits to sustainable practices to avoid the destruction of our species.

History of International Cli-Fi Day

Fiction teaches us about the world we live in. Human beings are not the only inhabitants of Earth. We are surrounded by ecosystems full of different forms of life: plants, animals, fungi, protists, archaea, and bacteria. These different forms of life interact with each other in perfect synchronization. Human activities interrupt this perfect interaction, which has consequences for our planet. Nowadays, the genre of climate fiction or cli-fi is emerging and teaches us about the climate change crisis that will affect our lives for as long as we inhabit Earth.

In simple words, climate fiction is stories or films that deal with climate change or stories about global warming. It is often speculative and tries to show how humanity would deal with a climate disaster in a world similar to our own or the future. Technology that has been built to combat climate change is often included. The term climate fiction is relatively new. It started gaining prominence around 2010, in light of our more recent knowledge of the seriousness of climate change. Nowadays, more and more books are surfacing about the topic.

The term ‘cli-fi’ was created by freelance writer Dan Bloom in 2011 in a press release for Jim Laughter’s “Polar City Red — a Novel” dealing with climate refugees in a future Alaska. Bloom published “The Cli-Fi Report,” an online resource serving all things climate fiction. Climate fiction highlights and intensifies the present and future risks of climate change in a way that reporting simply cannot.
