The Drowned World

Kim Stanley Robinson's Forty Signs of Rain feels more down to the ground, but I suppose that there are plenty of other recent science fiction books about climate change.
And Paolo Bacigalupi's The Windup Girl present a more complex world where there was an important sea rise due to climate change, but a lot of other things happened in different areas, in different ways. Is not as accurate as the previous one, but is more entertaining as fiction book.
In the book, most people don't care until it's too late, and then they adjust to the post-apocalyptic world with a combination of violence and resignation.
