If magnetic north is headed towards Siberia, then it could answer what has happened there before. There is no doubt that creatures such as the wooly mammoth have been found basically flash frozen in the tundra. Their stomachs still had vegetation in them. This indicates that there was dramatic change (violently and quickly) in the position of the earth as well as a possible pole shift. The bible says that in the endtimes the stars will fall from the heavens. Could it be that what is southern sky in reference will move north? Possibly what is equatorial in nature could be the new arctic and quickly.
