Thread: Magnetic Shift Winter of 2012

Some say the world is going to end in 2012, consequentially it is the year of not only a magnetic shift within the earth but a solar maximum during winter. What does this mean? Our magnetic field around the earth will be completly switching around withing a time frame of a couple of days (magnetic north goes to magnetic south vise versa) the sun will be emitting its maximum amount of radiation during this shift, and it is also going to primarily occur in winter which is when the earth is closest to the sun.

Usually our magnetic field is there to protect us from particle radiation from the sun, especially needed during a solar maximum. But during the time the field is switching at one point certain areas won't have any magnetic field other than a similar version of our north and south poles and only have repulsion of only oppisitly charged particles. Areas now exposed to solar radiations will be bombarded at a much stronger, closer to 90 degree angle making the radiation more direct and much less likely to be dispursed and weakened by our atmosphere.

During the magnetic shift and solar maximum we will be extremely vulnerable to solar radiation, possibly causing greater risks of cancer and auroras through places they have never before been.

This is all just speculation of some apocalyptic prophets. The year 2012 has no significance whatsoever, except for some esotherics (Mayan calender, etc.). The doomsday story has so many different flavours: some say it's a comet or an asteroid hitting the earth, others come up with a different catastrophe. I think, you just found yet another. Sure, the magnetic field changes its polarity from time to time, but none can really predict, when the next shift will occur.

Yeah, don't believe any of it. The earth is more or less the same distance from the sun during winter and summer. The seasons are due to the tilt of the earth's axis, so while the northern hemisphere is in winter, the southern hemisphere is in summer and vice versa. It makes absolutely no sense to talk about the "earth during winter". As for the magentic fields; yes, they switch from time to time, but it is almost certainly gradual and is most definitely not predictable to within a year.

What radiation do you think we will be vulnerable to? None of the electromagnetic radiation is blocked by the Earth's magnetic field. So you must mean charged particles. Which charged particles in the solar wind are going to make it through ten miles of atmosphere?
Here's another thought: do penguins and polar bears suffer from a great deal of cancer? If not, why not? They live right where the descending lines of the Earth's field direct solar charged particles.

Moreover, as Kalster pointed out, it makes no sense to talk about a solar maxium during the winter. And as Kalster and Dishmaster noted, but I would like to emphasise, a magnetic reversal probably takes of the order of one thousand years and pretending one can pin it down to a specific year is ludicrous.

Based on the Phanerozoic record of pole-shifts, no one can predict with any accuracy when the next one will occur.

Secondly, the magnetic field does not disappear during a pole-shift - it just becomes horribly skewed.

Third, there is no extinction event correlated with a pole-shift.

My understanding is that although Earth's magnetic field does a nice job protecting us from bombardment, failing that the atmosphere would anyway. Is that about right?

Besides the bipolar nature of the magnetic field, there are also multipoles. Although they are much weaker, they are still capable of at least some protection.

We don't see dramatic effects in the north and south poles mostly because the sun's emissions there are at an extremely acute angle ( causing low energy density). As we approach the equater the radiation becomes more and more direct (eventually to hitting at a 90 degree angle) and more and more concentrated as will any other particle(s) being emitted from the sun.



Every 299 thousand<x<300 thousand years the magnetic polarity within iron layers has switched according to geological records.
Also it is proven that the shift happens within a year. This is also proven by records of magnified metals in the earth (mostly iron). Simply put they can look at the polarity of layers of iron within the earth and determine that so and so years ago it was oppisitly charged ----> to a short period of transitioning to todays charge ------> to being in accord with todays magnetic polarity. The transition period inbetween oppisitly charged and todays is estimated one year.


My friend today mentioned the changing of the magnetic fields causing shifts in the tectonic plates causing magma spews and earthquakes.

What is this, viral marketing for that retarded Sony 2012 disaster movie? http://en.wikipedia.org/wiki/2012_(film)

Hell, maybe I shouldn't have posted a link to it, I'm probably only giving them what they want.

The 'records' you cite are clearly in error, as they do not match the records geologists actually use, such as the one above.

(Berggren, 1995. Late Neogene chronology - new perspectives in high resolution stratigraphy. Geological Society of America bulletin, vol. 107, no. 11, p.1272-1287.)

This is also nonsense.

Do you acutally know the TIME those bars represent??

And I never really thought that the world was going to end or be partially destroyed in 2012, I just wanted to bring all the ways i have herd its going to happen up to people on the forum.

First thing i thought of was we can't prove when a magnetic shift is going to happen, BUT I have heard from many of my science teachers that it will happen soon. IT IS DEFINITLY more likely to happen soon that 3million years from now if you look at the patterns in the chart.

If in our lifetime the magnetic shift happened can you honestly say that nothing would happen?

Does anyone even know HOW LONG it takes to completly change polarity?

The graph provides the approximate time of each interval of normal/reverse polarity.

A shift will likely happen soon, but 'soon' in the geological sense. 'Soon' we will also be in the midst of another period of glaciation, but neither of us will ever see it.

I can claim to honestly believe nothing would happen. What actually would happen is beyond my knowledge except for what the fossil record shows - no extinctions beyond the background rates.

Does anyone even know HOW LONG it takes to completly change polarity?

The general consensus is ~3000-5000 years.

3-5k years lol good stuff
