The Earth's magnetic poles have shifted on the past, multiple times. Current understanding of polar magnetic shift is that, like Earth's precession, such event is an expected, regular occurence. Perhaps, the magnetic shift will interfere with current electromagnetic technical civilisation we have built in the last century. It may be interfering with internal sensors of many animals, resulting in the increase of aberrant behaviors.

For men with little to no abilities to function within the current sociocultural matrix, the apocalypse is a very comforting notion. Because these men have nothing, a reset of the human condition to zero would actually be a step up for their future prospects. The obsessive fascination of modern culture with the end of current sociocultural system (whether it be Zombie apocalypse, international economic meltdown, shape-shifting reptiles farming humans for food, or imminent nuclear war) seems to illustrate the hopeless reality of the misled younger generation.
