It's on the move!
Earth's Magnetic Pole Is Wandering, Lurching Toward Siberia
So sad I feel for the younger generation this looks really bad
50 years worth of movement there
i heard if it flips upside down, which happens, we're fucked, but this reckons its not so bad
Why You (Probably) Shouldn't Worry About Earth's Magnetic Poles Flipping
Nautical charts usually have a compass rose on them showing the local magnetic variation, eg
(random googled example)
E2a but yeah if a once in c.100,000 years poleshift happens (we're well overdue iirc) then we're all fucked
I thought it took a long time for the actual shift to happen? Over 150 years....It's not something that will suddenly flip.
Another sign of the end times
Yeh they said the same thing about mps and their houses
"In Soviet Russia, north pole navigates by you!"

This will not affect non ionising radiation rates coming into to Earth, only ionising. Those will largely be trapped by molecules in the upper atmosphere that will filter down to the lower atmosphere. There is a weak but plausable link to increased cloud formation due to nucleation.

But over all little to be overly concerned about so far as I can see.
Others may have more information that undermines what I have said.
We’re overdue a reversal of poles as it is.
Geologically speaking, that is very sudden!
And when you tell them "I remember when it was all magnetic fields there", they won't believe it.
Another thing to blame the Poles for. Farage won't be happy.
Interesting to note that the early WMM update will have to be propagated out to smartphone OSes (ie it is a part of the Android codebase) in a system update if the built-in Hall effect magnetometer outputs are still to be (reasonably) accurately related to compass directions.
You is one crazy dude.
The old adage of 'Mag to Grid, get rid' is out of the window in a fair part of the UK now. Mag North was traditionally to the west but is going east. For users of normal compasses (such as Silvas) the difference is well below the resolution of the compass and is pretty much ineffectual at the moment.
