Do you think "clifi" makes a difference in the global warming debate or has already become commercialized in a way that just turns it into entertainment?
Hello Jeff: Yes, I've wondered the same thing. But any central motif can be treated both seriously and commercially. (Chick Lit is Jane Austen lite, but that does not invalidate Jane Austen.) "Entertainment" -- unless a thing is entertaining in SOME way, it won't hold the attention of anyone. But if it is only entertainment, it will be quickly forgotten. What will really make the difference in the climate change debate will be -- unfortunately -- droughts, wildfires, floods, violent storms, famines, and the other ills that extreme weather conditions bring with them. Alas.
