As the American west continues to dry out, science fiction about climate change is beginning take hold. Books from authors such as J.G. Ballard, Margaret Atwood and Paolo Bacigalupi are creating a new subgenre: Climate Fiction, stories about Earth and how its changes are impacting humanity.
I like the post apocalyptic re-branding comment below. The concept does sound like new wine or old bottles.
There have been oodles of books dealing with climate change / end of world due to human and natural mismanagement / misalignment.
Perhaps the seriousness /plausibility ratios are closer but authors have been writing about this for at least a century and that just includes reactions to man’s effect globally through WW 1.
