I read a while ago that the north magnetic pole has been moving more rapidly in recent decades. Could that be leading up to a flip? Someone suggested that they flip at roughly 60,000 intervals. Anyone know if this is right? Also, when was the last time they flipped? I think the author is confusing fallow fields with consequences that follow.
As I understand it (which isn’t all that much) there won’t be much different after the polarity shifts.
But the risk is in the period of shifting, while the magnetic fields lose the strength to shield against radiation from space.
Or something like that.
Most of what you said or asked about is under debate, but theorized as possible. A simple google search could answer your question about the intervals and the last time it flipped.
Here’s an interesting question. If the north pole has been moving more rapidly, has the south pole done the same (stayed in alignment with the north) or not ? If not, why not ?
The consequences are not all that horrible. There will still be a magnetic field. We will still be protected.
Compasses will have to be adjusted. Butterflies might migrate the wrong way. But there isn’t much to do about that.
