@themipper I recommend A Half-Built Garden by Emrys! It's a really lovely and wholesome climate utopia, and it's set in a not-too-distant future which makes it much more concrete and grounded.
It also stands out for having a world that is still kind of messy. For the most part, they've gotten rid of capitalism and the nation-state, but it's kind of like monarchy is today - figureheads and enclaves remain whilst most of the world has (effectively) moved on. It's some really rich world-building.
