"Films have always explored the frightening possibility of living in a dystopian future and nature has been an antagonist in horror since The Lost World (1925). The subgenre of "eco-horror" is made up of films where the scares comes from the environment, especially in cases where human interference has caused nature to "fight back", like in Alfred Hitchcock's The Birds (1963) and Steven Spielberg's Jaws (1975). Eco-horror can include creature features, shark attack movies, sea monster movies, scary movies about tornados, pandemic/outbreak movies, and earthquake movies.
This list catalogs scary climate change movies. The criteria we've used for "scary" is that the films use climate change as the reason the characters find themselves in a dystopian setting, have thrilling scenes in which the antagonist is natural phenomena caused by climate change, or the film discusses climate change and is just unsettling in nature (see First Reformed below)."
