It could even cause other catastrophic conditions, so aviation would be the least of our worries.

Personally, I don't think anything will happen on December 21st, 2012. It would take a very large astroid or another planetary body to cause a sudden and a drastic shift of the poler regions.
The change in poles could allow solar flares to affect our satellites and maybe life on earth, if there's a 90 degree shift in the magnetosphere, wouldn't it? BTW, why is my italics stuck?

Solar flares affect satelites slightly, even without any shifts in the poles, but a 90-degree shift would definitely be a major catastrophy, then a chain reaction of other catastrophic events caused by such a shift, like tidal waves, major climate changes that will cause flooding, very strong hurricanes, and tornadoes like we've never seen before.

On the italics getting stuck... I don't think that's caused by shifts in the poles... FYI, place the [i] syntax, at the beginning of the italic text, which is an instruction to the web application to start the italic text, then a [ /i ] (without the spaces) right after the last word you want italicized. Example:
Normal text [ i ] (an "I" enclosed in the square brackets without the spaces) Italic text starts here, then [ /I ] to end the Italic text.

Also, if you click on the "I" symbol at the top left of the text window where you type your message, you'll see the application placing the Italic symbols for you.

Are you talking about a sudden change of the global poles? Or the magnetic poles?

Both, and feel free to correct me if I'm wrong, it is also believed that a sudden change in the global poles will cause drastic changes in the magnetic poles as well.

There are two sets of poles:
  1. Geographic poles: what the rotational axis of the earth runs through. It is the rotation of the earth about its axis which creates (or assists in creating) the weather, climate, and the tides.
  2. Magnetic poles: generated by the magnetic mass inside the earth. It creates the magnetic field which deflect solar radiation and make compasses work.
There is no mechanical link between the two. If the magnetic poles shift, they will not shift the geographic poles. The only way that I can see the magnetic poles affecting the geographic poles is if the weight of the magnetic mass inside the earth were to shift in such a way that it would cause the earth's rotational axis to be nudged from where it is today. But the shift would be caused by the weight, not by the magnetism. The geographic poles do shift minutely when there are major earthquakes.


In order for the geographic poles to shift dramatically, we would need to be hit by a very large asteroid, meteor, etc. In this case, it may or may not affect the magnetic axis. But like MagnumMike said, it will be the least of our worries.

Wow - Great reading and lots to think about!

When I originally posted, I posted under the idea that the magnetic poles would suddenly, drastically - flip - or move very far to the opposite orientation. I wondered then if something like that would have an affect on the tilt or movement of the planet itself, leading to weather and temperature changes, etc.

Sorry to have caused any confusion with my original post, but at least it has shown that there is a lot to think about with a scenario like this . . .
