This liminal moment, when the signs are everywhere that the climate in which human civilization developed is gone, seems a natural subject for fiction, and a number of recent novels have grappled with it—Nathaniel Rich’s Odds Against Tomorrow, Barbara Kingsolver’s Flight Behavior, and Ian McEwan’s Solar among them. These books have been labelled “cli-fi,” but chances are that the name won’t stick. It makes the genre sound marginal, when, in fact, climate change is moving to the center of human experience.
