And I still need to make it down the big hill to get to my interview tomorrow morning.
This does bring to mind the novel The Sixth Winter by Douglas Orgill which was published in
the '70's. There is/was a theory that a new ice age could start in as little as six winters if all the conditions are right. This is a fictionalized account of just such an event. It has been years since I have read it but I do remember I very much enjoyed it. One image that stuck with me was of a group of Soviet soldiers being attacked by a large pack of wolves. Including the unfortunate fellow in an APC who gets his head chewed on while it is sticking out of a hatch. According to the story, with the coming of the ice age, the wolves instinctively gather in larger packs and become more aggressive. This is one of the reasons humans have such a deep-seated fear of wolves.
This would make a fun RPG scenario, either a one shot with the characters trying to survive and make it to a warmer climate or as a small campaign. Maybe for Barbarians of the Aftermath. I may have to think on this more.
