Nothing new or surprising, but hardly alarming.

 

The magnetic poles of the Earth are always moving around. This causes a difference between Magnetic Heading (based on Magnetic Pole) and True Heading (based on True or Geographic Pole, 90 degrees). By the way, the Magnetic North Pole is somewhere off northwest Canada.

 

The difference between the Magnetic Heading and True Heading is called the Magnetic Variation (MagVar).

 

For navigation, large passenger aircraft have inertial reference units (IRU) that figure out the True Heading through the use of gyroscopes. The Magnetic Heading is then calculated by taking into account the MagVar. So the IRU has the MagVar uploaded inside - in the form of a huge database or tables, giving the MagVar to be used for every possible location on Earth.

 

Note: Aircraft do not just rely on a magnetic compass for navigation because of inaccuracies resulting from the dip in magnetic field lines (magnetic field lines do not run parallel to the surface of the Earth). This is where gyro compasses come into play.

 

Anyway, back to topic, every 10 years, the accumulated shift of the Magnetic Pole (yup, it's moving all the time...) becomes large enough such that the MagVar tables have to be updated in order to ensure accurate navigation. So every 10 years, airlines will be issued software by the respective providers for updating. If I'm not mistaken... the next update is around 2015??

 

So the Mayans predict that this'll be a major update??? [laugh]

 

Sometimes, knowing some technical details and science helps to keep us all grounded in facts... and not get alarmed over all kinds of "predictions".
