"These novels are a tool to explore how climate change is continually subjected to a form of cognitive dissonance, and, therefore, the novel can change how we sometimes fail to think about climate change or displace the problem onto future generations," says Mr. Crownshaw.
I'm guessing that the "cognitive dissonance " referred to here is critical skepticism. So I'm guessing as well that the failing to think means not thinking a certain way. Which leads me to suspect that we are not talking about literature at all, but propaganda. Which would explain why the stories tend to be dystopic. It would be altogether possible to write a cli-fi novel portraying something on the order of a future garden of Eden and how that came about. But I guess fear is more useful for political purposes. Maybe someone should devise a tale of a world in which politicians are regarding as pariahs. That would be uplifting.
The Road, by the way, is not about climate change in the sense meant here. In that novel, something has happened to devastate Earth, but it would seem to have been on the order of a nuclear war, not global warming.Speaking of global warming, this fellow seems to have some credentials:
