It would then coincide with the procession of the equinoxes every 24k then? The graph of glacial/interglacial periods I shared above in #16 taken from ice cores shows a regular shift in the cycle on an average of every 24,000 years. I am firm believer that we set our sites to short trying to find just one cause, when it could be a combination of several different influences happening at the same time.
When we have a pole shift the magnetic field weakens making us very vulnerable to a large solar flare.
