The apocalypse feels unreal. Travelers walking across lava fields, as astronauts play golf with space sharks. Marching Through the Fire doesn’t depict what will happen after global warming. Instead, it’s the surrealness: the weight of hot air as ash sprinkles from the sky, the choking grip of smoke, the barren landscape on the horizon. Some will trudge on: life is tenacious. But a world consumed by flame is no world to live in.
