It's not what you think--some sort of enviro agitprop. These are literary artists responding to our situation head-on, as artists, and with striking results.
But it's not any clever sci-fi futurism that stays with you, or any mere didacticism. It's the acute psychological portraits, the way they cut through abstractions like "climate crisis" to bring it home, make it real.
I want to say these stories get at something desperately needed--a psychological realism, an emotional depth, almost completely missing from the climate "debate." I don't mean just a palpable fear (much less some naive hope). I mean something more like the will to survive, or the capacity to love, maybe even to pray. Something we understand as human.
