2 . If you can travel back in time, which period of history will you visit? It’s a great question to ask your friends, and time travel is the subject of many science fiction films. Of course, sci-fi is familiar to most of us, but what is cli-fi? The simple answer is climate fiction which focuses on the subject of climate change.

Many of the cli-fi examples we watch tend to be disaster films. The subject could be solar flares (太阳耀斑), ice ages devastating (摧毁) the planet, extreme flooding swamping the earth, or superstorms that threaten life. While films and novels of this style are often subject to the typical images of a hero or heroine battling to save the world, what sets it apart from most sci-fi films is that the plots will often draw on apparently reasonable outcomes in the near future.

Climate change and the potential threats have long been established. Some believe that the issue of climate change has even led to more fans watching films to learn more about what’s happening to the world — seeing it as a form of edutainment (寓教于乐型产品). A study conducted by the Yale Program on Climate Change Communication tested the effects that two climate fiction novels can have on their readers and found “significant positive effects” in terms of their attitudes towards the climate crisis — for example, understanding global warming will harm them and future generations.

Most cli-fi films not only are extremely popular action films, but also cause our fear of what some see as the approaching end of the world. This sounds bad, but according to a study conducted on 310 adults in the US, watching such scary films can help us feel more prepared and less alone in situations such as the pandemic. So, it looks like the cli-fi film is here to stay — and there seem to be some benefits. Whether it’s there to educate, entertain or prepare you for a climate crisis, it might have a role to play.
