Not as good.
The topics on Polar Shifts and magnetism were excellent and I'm going to look into those a bit more now as well, but the stories seem a bit too much to even be considered as true. It's interesting to think about, but will remain a tale into new evidence comes forth. There just simply isn't enough evidence to back up what you're saying.
On the topic of polar shifts though, I'm extremely interested. Since the Earth's plates move according to the rotation in the core, and since our monitoring equipment isn't enough to measure EVERYTHING accurately, it's definitely possible for things to change rapidly. However, what I think is the case, is that because the cycles for polar shifts are reducing, down to what you say is 13,000 years now, this would mean one of two things. The core is speeding up, or the more likely possibility that the earth's core is slowing down. It would all depend on how much friction there would be between core movements and the plates on the surface of the earth. The instability between the magnetic fields accounts to this slowing down because of how simple magnetics work. The faster you can get a motor spinning to create an electromagnetic field, the more stable that field will be. Conversely, if it were to slow down, the field would be unstable like how you say it is now.
These are just my thoughts, take them as it is. Keep up the good work with this series though. :D
