Which way is north? The geographic North Pole is a fixed spot. But magnetic north is another story; it's where lines of the magnetosphere converge, and Earth's magnetic field is hella dynamic. Every 5 years, scientists revise the model for magnetic north & they recently released its latest update 🧪

Shift ongoing due polarization of alignment decay over time Earths orbit correctional pull elongation upon pattern shift during corrective change along point during apex which just began will conclude approximately by 2037
Takes fifty years adjust our trajectory before Earths polar shift correction.

True. The magnetic poles have been moving ever since the Hadean when they formed, which fortunately for us protects us from all sorts of nasty space radiation.

Friendly request: please avoid the trap of the unnamed "scientist they." Give credit.

From the link: "The World Magnetic Model is jointly developed by NOAA National Centers for Environmental Information (NCEI) and the British Geological Survey (BGS)."

(excellent link, thanks!)

GPS-based navigation instruments orient me and my boat.

The beautiful compass which sits just forward of the steering wheel of my sailboat is essentially a decoration.

There's a reason why Canada labels its runways to geographic north, and it's because magnetic north is a wobbly little bitch.

canada's Southern Domestic Airspace set its runways to magnetic throughout my flying career. northern domestic was true , and often our charts up there referred to grid north just to save confusion
