Yes! My Space Corps trilogy takes place in the near future, where workers have succeeded in taking over the world and have begun to explore the galaxy. The whole thing is available on libgen. The third book in particular deals with climate change as well as future stages of the revolutionary struggle, where new generations arise to sweep the old aside. The first book was inspired by the Iliad; the second, by the Odyssey; the third, because I had run out of Greek epics, by Gilgamesh. No need to feel any guilt about reading it for free; just please tell others about it if you like it.
Sorry for the late response—yes, physical copies exist, and you can get them from amazon.
