Gcaptain article- "early update to World Magnetic Model"


#1

Just read this excellent article, and followed on to the NCEI.NOAA site. Also interesting.
The site links to a really good phone compass app - CrowdMag - best I’ve seen!
Just one thing - when did magnetic variation become magnetic declination?
(Enough deviants on the planet already!)

Scientists say the unplanned update of the WMM comes as the Earth’s northern magnetic pole unpredictably moves quickly away from the Canadian Arctic towards Siberia.

how good is your fake news game if you can even convince the geodynamo to defect? SAD!
