I agree. It's an opportunity too often missed. I think of books, TV, movies as the way way society dreams, often working through scenarios, good and bad, so that we're better prepared to confront them when we see them in reality, having thought about various hypotheticals.
The mainstream public doesn't always want to get caught up in the mechanics, though. They want a good story. So it matters to do that component well. Climate Change can be depressing to think about. You want stories about characters you care about, and with luck maybe you can find rays of hope that show the importance of doing positive things, whether societally or individually.
I really enjoyed the Showtime series The Affair, which ran 5 seasons. But its fifth season jumps forward in time and takes place in the future and they chose a Climate Change angle to set that off. It's not just window dressing, it's integrated into the plot in substantive ways, but it's not so heavy-handed that it feels like it's a show about Climate Change. I really recommend having a look at how that was done for a model of what might be done in the middle ground space.
