TAMPA – Scientists say the magnetic north pole is moving toward Russia and the fallout has reached — of all places — Tampa International Airport.
The airport has closed its primary runway until Jan. 13 to repaint the numeric designators at each end and change taxiway signage to account for the shift in location of the Earth’s magnetic north pole.
The Federal Aviation Administration required the runway designation change to account for what a National Geographic News report described as a gradual shift of the Earth’s magnetic pole at nearly 40 miles a year toward Russia because of magnetic changes in the core of the planet.
Found by ECA.
It’s climate change! Call Al Gore! We need to set up a Magnetic Credit Exchange! We have to be at fault!
How long does a magnetic “flip” actually take to accomplish? I’ve googled this several times and haven’t found an answer. I assume it could take several hundred years. But probably much longer as obviously birds are able to adapt to the change? From memory, the history of the flip is written in sea bed lava flow showing a flip every 50K years or so? God laid this record down to communicate to us that that was his “plan” for us going into the future. That is how omniscient god is: he’s got all the details worked out to the last detail. Come to think of it, he must have programmed the birds to adapt to this expression of his will as well.
God: my best friend, and your’s too if you will just let him into your heart.
Runways are numbered to the nearest first two digits of the magnetic heading.
180 = 18
But so does 176, 178,179,181,182,183,183 & 184
So if that runway was one degree off the switch over for the last [LARGE NUMBER] of years then this isn’t news.
40 miles per year? That would be 4000 miles in 100 years, 1/3 of the way to the South Pole. Why isn’t this a bigger issue than global warming? Is it moving in a circle or spiral?
I can’t answer for the USA, but UK maps have information on how the magnetic variation (from true north) changes over time.
This has nothing to do with climate change, polar flip, aliens, government conspiracies or even any forthcoming end of the world.
Presumably, the closer you are to the (north or south) pole, the greater the variation and the more it changes.
Are there any pilots here? I believe airports have been doing this for a long time.
Magnetic compasses are surely just a back up device nowadays. GPS is everywhere, then there is INS and RDF.
“Why isn’t this a bigger issue than global warming? Is it moving in a circle or spiral?”
– Man has no impact on this shift. We did not cause it, nor can we change it.
On a related note…Al_Yea – shut your trap, you moron.
Holdfast==the iron core that forms the Magnetic North Pole floats around in the top part of the molten middle of the earth. It is closer to the geographic North Pole and therefore changes in its position there create larger changes at the poles where the lines of latitude converge.
I think your presentation confuses the change in this variation with the “history” of the change. I have never seen a map showing the “rate” of change of variation: no reason to. Aviation maps are issued quite often ((I want to say every six months, but I could be wrong)).
I don’t know what a polar flip is but the flip of the magnetic poles is totally relevant. At the time of flip, whatever that actually means, the magnetosphere stops deflecting radiation from the sun. That would argue for a short time of flip duration otherwise there should be massive die-offs every 50K years, and I don’t have that in mind.
Well, shoot. Time for the google.
I’m pretty sure this shift is anthropogenic.
Not really all that straight forward.
1590 to 1990
Nothing to see here. Please move on.
The Russkies are STEALING THE NOTRH POLE !!! Call Issa, we must have a Congressional Investigation !!! Maybe Issa can subpoena Putin !!! We might even have to send Blackwater “Contractors” to STEAL IT BACK !!!
Fuckin’ Magnets!! How do they work?
This happens all the time. I remember the Johnstown PA airport (JST) doing the same thing the 1980s.
I have an old map of Colorado that shows the magnetic declination at 7 degrees. It is now 9 degrees.
That’s why you shouldn’t solely rely on a compass long distance navigation.
Bobbo bloviating on GOD? Miracles really DO happen apparently.
# 2 bobbo, “How long does a magnetic “flip” actually take to accomplish?”
According to one NASA scientist, 400,000 years.

However, the last one (the Brunhes–Matuyama reversal) was about twice that long ago.
In any case, I can’t document it right now but I’m sure when I was learning navigation for my pilot’s license, they taught is the magnetic poles wander. It may be moving toward Russia right now but it might start heading for San Diego soon.
#5 Holdfast – Yes, EVEN in the USA we update our navigational data every few centuries. Sheesh…
Whew, that was close. I still need to google magnetic flip, every 50K years or 75K years as I recall. NOT THE SAME as continental drift that you are confusing it with. Although, magnetic flip and continental drift are both caused because we have a liquid/molten/radioactive center allowing for both phenomenon: the statistically impossible universe. With your example shaming me, I will do a quick google: ………yep, right there with a different name. My answer is in the last paragraph.

Glad you got home Animby.
This guy is falling. Ten times. Fast.
Bobbo #16 – Not sure what you think I was confusing. The man says, “…the magnetic polarity of Earth, which does change irregularly with a magnetic reversal roughly every 400,000 years on average.”
Not that it really matters. It’s gonna be a long time,yet. The wandering northern polarity is unlikely to hit Antarctica for a while, yet.
Thanks. I had a good trip. Weather wasn’t great but that’s only important to me when there isn’t a bright sun, I forget to slather on the sunscreen. I am sooo white. Worst is the top of my follicularly-challenged head bobbing in the ocean waiting for the pickup boat. One guy was wearing a baseball cap. I may have to learn to dive that way. Had a close encounter with a whale shark and saw my first ever “herd” of hammerheads.
Damn. Why do I have to work? There are so many better things to do…
I don’t remember much of my training in navigation since I’ve been out of the Navy for fourteen years, but I do recall speak of gyroscopes to tell direction. This is especially handy near the actual magnetic north pole since a magnetic compass will no longer point North near the magnetic north pole.
The magnetic north pole will probably screw up all kinds of ocean charts too because they do have a notation saying how far off true north is from magnetic north.
Starting now, let’s use the SOUTH pole and everything will be fine!
