80 Deg. in 13 days would be eventful to say the least...........Any speculation on what might be the result of such a rapid switch??????

Yeah, possible 300 mph winds for one.

[RdSnt]

That would be huge nearly right angle and what the equator is now would be the north pole. That would mean the equator becomes cold and the poles hot..? Just my unscientific speculation.

Sigh
Nothing much would happen. The magnetic field may shift but the earth's rotation would not. No the equator would not change and no the north pole would not suddenly get really hot.

The earth's rotation is not generated by the magnetic field. Conversely, it only a theory that the magnetic field is generated by the spin of the earth. In the end we don't know for sure what is creating the magnetic field.

[StormBringer]

Either way it would be intense to happen so quickly. And there are theories about the mag shift and the continental plate drift being linked. Now if this drift was to suddenly change direction???? Just food for thought....

A lot of people who like to use the compass in their mini-van to see what direction they are going would be very, very confused.

Or something...

"At the heart of our planet lies a solid iron ball, about as hot as the surface of the sun. Researchers call it "the inner core." It's really a world within a world. The inner core is 70% as wide as the moon. It spins at its own rate, as much as 0.2o of longitude per year faster than the Earth above it, and it has its own ocean: a very deep layer of liquid iron known as "the outer core."

Earth's magnetic field comes from this ocean of iron, which is an electrically conducting fluid in constant motion. Sitting atop the hot inner core, the liquid outer core seethes and roils like water in a pan on a hot stove. The outer core also has "hurricanes"--whirlpools powered by the Coriolis forces of Earth's rotation. These complex motions generate our planet's magnetism through a process called the dynamo effect." link

So what is everyone's opinion of the effects of a sudden change?????? Anyone.......?????

Not a problem.

"A south magnetic pole might emerge over Africa, for instance, or a north pole over Tahiti. Weird. But it's still a planetary magnetic field, and it still protects us from space radiation and solar storms."

[Roy]

would the Northern Lights be over Tahiti then?



I guess they might: http://en.wikipedia.org/wiki/Aurora_(astronomy)

Auroras, sometimes called the northern and southern (polar) lights or aurorae (singular: aurora), are natural light displays in the sky, usually observed at night, particularly in the polar regions. They typically occur in the ionosphere. They are also referred to as polar auroras. In northern latitudes, the effect is known as the aurora borealis, named after the Roman goddess of dawn, Aurora, and the Greek name for north wind, Boreas by Pierre Gassendi in 1621.[1] The aurora borealis is also called the northern polar lights, as it is only visible in the sky from the Northern Hemisphere, the chance of visibility increasing with proximity to the North Magnetic Pole, which is currently in the arctic islands of northern Canada. Aurorae seen near the magnetic pole may be high overhead, but from further away, they illuminate the northern horizon as a greenish glow or sometimes a faint red, as if the sun was rising from an unusual direction. The aurora borealis most often occurs from September to October and from March to April. The northern lights have had a number of names throughout history. The Cree people call this phenomenon the "Dance of the Spirits." Aurorae can be spotted throughout the world. It is most visible closer to the poles due to the longer periods of darkness and the magnetic field.

Sure, or this

or this refinement to the dynamo theory: link

would the Northern Lights be over Tahiti then?

Yes. "And, as a bonus, Tahiti could be a great place to see the Northern Lights. " see link

Provided it's not underwater.

[StormBringer]

wouldn't it be possible that the earths tilt will shift or is it just accident that the magnetic poles happen to be north south...I mean if this switch happens every 200000 yrs or so and geological history points to a very different climate in several parts of the world without much of a plausible explanation perhaps the mag shift can be linked....Anyone??????........Please I'M not trying to be a smart ass just curious so don't slam me here....LOL

Recent research
Recent work by scientists and geologists Adam Maloof of Princeton University and Galen Halverson of Paul Sabatier University in Toulouse, France, indicates that Earth indeed rebalanced itself around 800 million years ago during the Precambrian time period.[8] They tested this idea by studying magnetic minerals in sedimentary rocks in a Norwegian archipelago. Using these minerals, Maloof and Halverson found that the north pole shifted more than 50 degrees — about the current distance between Alaska and the equator — in less than 20 million years. This reasoning is supported by a record of changes in sea level and ocean chemistry in the Norwegian sediments that could be explained by true polar wander, the team reports in the September–October 2006 issue of the Geological Society of America Bulletin.[9]

There are a number of different factors that are being talked about and bunched together as one thing.
We have the polar wobble, the magneto system that is theoretically responsible for some/most of the magnetic field, there is the spin of the earth and then there is the polarity switch that has been reasonably confirmed.
While there is a connection between them all, a dramatic change in one of these does not mean a dramatic or even any change in the others.

The most obviously is polarity switch, where the north pole becomes the south pole. This can happen reasonably suddenly and make virtually no difference in any of the other mechanisms. Although there is some speculation that the when the polarity switches the field actually collapses and then rebuilds. That could be bad obviously, since our cosmic ray protection would be gone for some appreciably time. However, the spin of the earth, and gravity and position of continents wouldn't change.

The polar wobble, which is well understood and predictable, with regards to how the poles drift, is speculated to be based on a wobble in the core's spinning core.
The core will not suddenly switch direction, that is mechanically impossible. Nor will the core suddenly stop spinning. Even if it did, that would not appreciably change the spin of the earth. Nor would the magnetic field suddenly disappear.

It's not an accident that the magnetic poles are more or less in alignment with the spinning poles. The core's spin is in alignment with the rest of the earth. But, again, polarity switch is not the same thing as pole drift.

Think of the earth as a very large gyroscope. There is an enormous amount of momentum that has built up. The spin is indeed slowing down, but that has more to do with the gravitic influence of the sun and at some point in the very far future the earth will be in a tidal lock with the sun, much like our moon is with us. And that may not occur before our dying sun eats us.

What Stormbringer might be referring to is the idea that is put forward in the books Path of the Pole and Maps of the Ancient Sea Kings (titles out of my head, might not have gotten them exact). The author suggests that the earth's crust can come loose from the underlying core and start moving much faster than normal, causing both a pole shift and extremely high winds. His hypothesis is that ancient maps show Antarctica as the center of the world, with the other continents around it, which would mean (presumably) that it was livable enough for relatively advanced civilization, thus it was in a different spot relative to the north/south poles.

Don't know if that's what happened, but it would explain the lost continent theory. Hiding right in front of us

Seems to me that the dislocation (if such a thing happened with pole shifts) would leave evidence in the fossil record with mass extinctions.

Is there such a correlation?

Well, it would explain things that seem to argue for "the flood", such as large amounts of fossils there to begin with. Fossils are not formed by just some animal laying down to die -- the body has to be covered with a crushingly heavy amount of dirt/silt/clay all of a sudden or else it'll just rot and turn to dust like all the other animal skeletons out in the forest/desert.

[StormBringer]

There are many bottleneck events in history which happens to come about every 200000 to 300000 yrs just about the same time window as the mag pole shift. Now weather this is wink dink or not who knows but they do have a correlation.
