I'm not sure it totally fits, but Always Coming Home by Ursula K LeGuin was an amazing read. The premise is that an ethnographer of the future is writing about a future, post climate change California people called the Kesh. Most of the book is actually stories the Kesh themselves tell, be it poetry, folk tales, an autobiography, and even a snippet from a novel.

It's an absolutely transformative book that I can't recommend it enough. It's like nothing else I've ever read.

"Psalm for the Wild-Built" is set in a solar punk world! Can't recommend Becky Chambers highly enough.
