Slow moving apocalypse?

Years ago I read “Soft Apocalypse” by Will McIntosh which described, as the title suggests, a gradual, multi-decade descent into a dystopian/climate ravaged world rather than the sudden shocks (virus, meteor strike, nuclear war, etc) that make up the majority of the genre.

Does anyone have any other recommendations of stories that depict a gradual slide into apocalypse (that maybe escapes the notice of people living through it)?

Thanks!
