I love George. But this, was unbelievable...the science is all wrong......they even briefly mention a colony ship that was supposed to launch just after this cataclysmic event. We as a race, would have pushed the launch of that ship. But, no they expect human kind to repopulat with one female and one male. The old man who is in the artic goes for a swim, and doesn't get hypothermia. This should have been written much better.
