Why do you think it's fictional? Or are you simply being reactionary, and haven't fully evaluated the topic?
Cloud seeding has been a thing since the late 1950s. It is a common practice, and has caused a number of flooding disasters from miscalculation of effect, in both China and the US. It is a "well accepted" practice and numerous US states have state programs to do so (North Dakota being one that's more prominent about it, doing it regularly to help maintain crop moisture levels). There is now significantly elevated levels of aluminum in accumulated snowcaps from the practice, and identifying the planes doing it (officially or illicitly) from flight data has become a pastime for many.
You can't tell me you've not noticed planes flying overhead and, instead of leaving a contrail which rapidly dissipates, it leaves a trail which slowly disperses, eventually becoming a smog of hazy, unnatural grey cloud cover? It usually happens on clear days when the weather is anticipated to be pleasant for several days, by the weather forecasters.
Maybe you live in an urban area and don't go outdoors often. It's quite evident elsewhere.
