TL;DR it's no cause for concern for now. Core is changing speed and direction in cycles.
Causing magnetic pole reversal?
Not likely, considering the last few times it happened it didn't. This is the first time it's happened since the 1980s, not the first time it's happened.
Clive Cussler lied to me!
Oh, much faster than pole reversal.
Which is neither the first time but every 100'000 years or so. Or was it 300k?
I wonder what kinds of affects this do have?
It would find it bizar if there are no natural phenomena connected to it.
The geomagnetic field is weakening which is common during these kinds of episodes and eventually the polarity of the magnetic field will flip so that north becomes south and vice versa. During the transition though we are likely to go from our bipolar magnetic field to a quadrupolar magnetic field where the north and south poles can fluctuate between two different points each instead of the normal single point. You can see evidence of this occurring in geological history through Ignatius rock, as it cools from volcanic eruptions.
Everything happening in the universe is "natural phenomena." If we can't explain it, we don't have enough information.
