Each of approximately 200 thousand years, the two poles of the planet earth, north and south of each shift. Generally, the two poles shift takes thousands of years.
Scott Bogue, geologists from Occidental College and Jonathan Glen, researchers from the U.S. Geological Survey (USGS), who observed the lava in the area of Nevada which has 15 million years old.
The result, from the research, they discovered that the planet’s poles have shifted several times faster than normal speed. It happens at least one time.

I am at a loss for words......
This story definately checks out, plus earlier I read where Chinese scientist have announced this today as well
Butterflies in my stomach......this 2012 stuff is NO JOKE
Put ya seatbelts on folks.........edit on 5-1-2011 by ButterCookie because: (no reason given)

I am not an expert in airport re-designation so I am not sure if this is a common occurrence. I suspect not.
After some 400 years of relative stability, Earth's North Magnetic Pole has moved nearly 1,100 kilometers out into the Arctic Ocean during the last century and at its present rate could move from northern Canada to Siberia within the next half-century.
If that happens, Alaska may be in danger of losing one of its most stunning natural phenomena - the Northern Lights.
But the surprisingly rapid movement of the magnetic pole doesn't necessarily mean that our planet is going through a large-scale change that would result in the reversal of the Earth's magnetic field, Oregon State University paleomagnetist Joseph Stoner reported today at the annual meeting of the American Geophysical Union in San Francisco, Calif.
"This may be part of a normal oscillation and it will eventually migrate back toward Canada," said Stoner, an assistant professor in OSU's College of Oceanic and Atmospheric Sciences. "There is a lot of variability in its movement."

Ok, my question would be, since when have the magnetic points changed their direction?
It's reasonable to assume if they can't answer these questions then they really haven't a clue as to what's happening..
It could change speed and direction at any time.
Runway designations change over time because the magnetic poles slowly drift on the Earth's surface and the magnetic bearing will change. Depending on the airport location and how much drift takes place, it may be necessary over time to change the runway designation. As runways are designated with headings rounded to the nearest 10 degrees, this will affect some runways more than others. For example, if the magnetic heading of a runway is 233 degrees, it would be designated Runway 23. If the magnetic heading changed downwards by 5 degrees to 228, the Runway would still be Runway 23. If on the other hand the original magnetic heading was 226 (Runway 23), and the heading decreased by only 2 degrees to 224, the runway should become Runway 22. Because the drift itself is quite slow, runway designation changes are uncommon, and not welcomed, as they require an accompanying change in aeronautical charts and descriptive documents. When runway designations do change, especially at major airports, it is often changed overnight as taxiway signs need to be changed and the huge numbers at each end of the runway need to be repainted to the new runway designators. In July 2009 for example, London Stansted Airport in the United Kingdom changed its runway designations from 05/23 to 04/22 overnight.

No it's not reasonable to assume that at all.
I'm not too sure of the validity of this diagram but I'd like to see anyone try to predict how and where the magnetic pole will move next.
It's all a variable, fact is though, right now the magnetic pole is heading towards geographic pole, it is moving back to the centre and not sliding out of the arctic circle.
It could change speed and direction at any time.
