World is changing

Question: I have a novel in which the world is changing in inexplicable ways and the protagonist goal is to protect his family and friends from the dangers of the change. What plot type does this fall under?
Well, if the story is like a disaster or survival plot, with no fantasy elements, in which the external situation is the antagonist and coping involves a lot of action, then I would classify the story under the Adventure genre.
However, you say the world is changing in inexplicable ways, which suggests the possibility of a psychological or fantasy component. Depending how that is developed, the story could fall under a different genre.
For instance, if you're aim is to create fear in the reader, stemming from a supernatural evil force which the characters manage to survive but not conquer, then you may have a Horror.
If the story is more about the character trying to figure out what is real and what may be their own delusion, then you might have more of a Psychological Suspense.
Finally, some magical realism stories ( a subgenre of Fantasy) use a strange and fantastical event as the catalyst that forces people to reassess or change their lives.
Hope that helps.
