Earth’s magnetic field is acting up and geologists don’t know why

So, does this mean Santa Claus moved?

He and Mrs. Claus now operate out of a food truck

[Nifster]

I’m good with it.

“in ways that planners had not anticipated.”

Imagine that.

what moves magnetic fields except a larger magnet or material more inductive to their waves acting as an inductor..

one reason...Let’s hope it is God approaching

[aces]

oh yea speed of the conductor and angle of incidence..same applies

[ml/nj]

They say the Magnetic Pole is heading for Siberia. I predict that it will turn around at some point and head for the Geographic Pole.

Just sayin'.

Cool find... Afraid to download it but going to read it.

it says it's a sanitized and unclassified copy. Makes me wonder what was in there that was objectionable.

[Openurmind]

I appears to all be there from what I read. I think by saying it has been sanitized means that they just reviewed it and allowed it to fly as is and good to go with an approval stamp.

But something you NEVER do is download files like PDF’s from a government site, just going there and reading is risky enough, let alone purposely downloading files and what might be included and hidden in these files.

Better to search around and find a source for it that is not linked to a government site.

I learned the hard way many years ago...

Somebody is in control of this planet, and it ain’t us.

Man I already did it. I hope I'm not being lumped in with some criminal mastermind who's master plan is to cause a global cataclysm by having a plan to make the crust slip.

[Openurmind]

Seriously... They can’t even keep their own machines clean of cooties let alone what they attach to stuff.

“Very goo! I wonder how many are going to point you spell check.”

Not me. But I will suggest going into the bilge of a WWII ship and stand next to the degaussing coils.

FRACKING! We’re all gonna DIE!

Where the magnetic north pole is located and the non- perfections in the local magnetic field are citical to long distance navigation accuracy. Think on transocean ships and boats and aircraft. The big dogs of transportation have onboard gyroscopes plus gps to replace routine use of a magnetic compass. The small dogs use GPS only. A failure of GPS and the gyro leaves all with the magnetic compass for navigation. The inability to accurately correct magnetic north to true north will literally lead to loss of property and lives. Updating the database described to adequate accuracy rates as a big deal.

HAB was the swapping of rotational poles, IIRC... This is the movement of the magnetic poles due to changes in circulation patterns in the deep mantle.

somebody took seriously... wonder how much more investigation was done and what they dint put up?

That document is pretty interesting. It puts up a cause that I didn't really digest before..that the mantle is usually relatively plastic and not flexible but periodically there are disturbances, or a explosion that causes the molten layer to become more viscous and then crustal displacement happens.

Kind of reminds me of liquidation in wet soil during an earthquake.

[Openurmind]

Did you read that yet? Fantastic references and citations.

[Chode]

the way i understand it, the pole is wandering because of magma displacement or rotational slip which was prelude to the poles shifting to the equator along with the heavy ice at the poles centrifugal(?) action

but what do i know... 8^)
