the Russians are stealing the north pole,
quick get Austin Powers.

 

The Daily Mail is not known for its high journalistic standards in the scientific and medical communities. Lots of click-bait.

 

That's the real deal, just like NO getting hacked. Hey, I'm on top of this stuff.

 

Here is something slightly more professional on the topic. Axios gives an explanation, and the climate-centric web site even compares movement of the earth's liquid outer core to "weather."

The poles are in constant flux. in fact many times in history they have swapped places.

The good news for Bill is many of the better navigation systems utilize the Coriolis effect to calculate where they are.
Coriolis effect is the push to the poles by a moving object due to the spin of the earth.

Combine that with GPS positioning and you have a pretty good idea of where north is. $$$ = accuracy.
While not applicable on smaller boats you can also use differential GPS to calculate the line of the two known fixed units.
The further apart the lower the error. of course this tends to be more accurate for slower moving systems.

 

Personally, I am only comfortable if I can see land but I never grew up around any large bodies of water.
