Geomagnetic reversal

Are we FUBAR'd?

A friend in Scotland loves showing me the intricacies in rocks from the different polarisation.

All I want to know are two things:
a) generally will I by FUBAR'd
b) if I am in a helicopter on a record play4er will I finally find out the turth?

You can't handle the turth !

[Simpo Two]

You will be fine. Just go in the opposite direction.

I expect there's a tacky low-budget sci-fi-eco film about just this subject, you know, the one where the maverick scientist is trying to get home to rescue his family while CGI rocks fall around him and it's all run by a big black bloke in army uniform in a control room interspersed with interminable shots of a family pretending to drive a 4x4 very fast on a dusty road and an actor playing President.

A. No. Probably not. Apparently it takes a 'few' thousand years to switch between the top and bottom of our planet. It seems as though it's been moving at around 27 miles per year for the last few years. That means that if you relied on a magnetic model that's a year old and set your satnav to Dover, you might end up in Calais.

Some interesting reading here if you want to have a look.

B. Only if you're drinking a bottle of vodka through the bottom of the bottle

Ah, re a) is that why magnetic north and grid north change over time then> I remember as a scout having to learn "MAGSGUMA" Magnetic unto Grid Subtract and Grid Unto Magnetic Add for compass bearings.
b) the bottle was definitely getting empty last night talking about gubbins like this.
