In the Ashayana Deane material that I have been researching they explain that pole shift is not a natural occurence and happens because of intervention in the areas around the tropics which is coordinated with scalar pulses from a black hole in the centre of the Milky Way
As far as I understand from the material, the straight pole shift was intended for 2003 and was prevented by shifting from probability one to probability three
There are efforts in this moment in the same sense and AGWWP (all going well weather permining
) if we can keep the light quotient steady in the planet we might be able to avert it in 2012
In their summary 2, Q & A section the Guardian Alliance explains some of this but also indicates that Earth changes are inevitable. Here is the link (just scroll down til you find the Q & A)
