They glaced over nuclear war a little too quickly. While I'm not an expert, I've heard many times that a significant nuclear exchange between countries would likely result in so much debris being thrown into the atmosphere it would cause a nuclear winter. This could lead to a full blown ice age, mass extinctions, etc... Surely those "side effects" of the bombs would be measurable far longer than the radiation. We know of past super volcanic eruptions and the dinosaurs' extinction because of similar circumstances.
