I have a fun snarky way to handle “cyclical” people. If they say it’s cyclical I’ll say “so there will be dinosaurs.” And if they ask what I mean, I say “it’s a cycle, so there will be dinosaurs again.” If they say no, I ask if the continents will come together again. It’s an argument towards absurdity to point out that the world is always changing, as is the climate, so there is not a “cycle.”
