I haven't read The Calculating Stars (yet), but from the description it sounds like the climate change in the story is caused by a meteor colliding with the Earth, rather than being caused by humans. That seems like an effective way to take climatic change out of its political context -- i.e., it's changing because of a deus ex machina, not because of anything done by any person or group of people. In our world, climate change is a political issue precisely because it's anthropogenic -- because it's something we're doing to ourselves so that some among us might profit. Why you'd want to take climate change out of its political context, I have no idea. Someone's who's read the book can speak to that better than I can. It seems like a weird choice, though.
