I've also read postulations that glaciers were not caused by 'ice ages' per se, so much as they were the remains of the north pole ice cap after a shift. I can't find the link right now to the information I found truly interesting (correlation of past poles with existing glaciers) but there's a fair amount of info out there about it. (Some people are correlating it with 2012/doomsday, so be forewarned.)
Oh good grief. TFA is about movement of the magnetic north pole. This has nothing whatever to do with the axis of rotation of the Earth, or its axial tilt. A wandering magnetic pole isn't going to cause glaciers, or probably any other climatic effect for that matter. A useless compass is about the maximum inconvenience you're likely to encounter. I suspect this "fair amount of info" about glaciation you're referring to is found on the same web sites as the 2012 apocalyptic garbage you seem to believe.
