The first three minutes of that movie are accurate, because a meltwater did in fact halt the thermohaline circulation and end an interglacial period in the past. Of course the thermo part dominates over the haline part now, and the rest is garbage. Tropical storm dynamics over the Rocky Mountains, gimme a break. But my whole atm dynamics class went to see it in a theater and it was fun times.
