Because of the enormous amount of comments to this 2012 article, I’ve had to move the comments to a separate thread, because the page was slowing down the server. You can continue commenting here.

poarity in men or animals change all the time without even noticing it without special instruments. WHY we thing in case of planet it will bring such calamity?? If we are aware such thing can happen we should be prapared for reversals in directions (specially in travel and flights) It has happened many times and it has happened in computer models and it will happen to us one day but WHY calamity??
> So, do you think there will be a geomagnetic reversal event in 2012? I thought not.
I’ll think for myself, thanks.
I did like the explanation of what we do know about the magnetic field, it’s a great writeup. But in the end, chaotic only equals not knowing enough yet to make a good prediction. So if we don’t know why it changes, it needs as much faith to believe it won’t reverse in 2012 as it does to believe it will.
Without GPS, our airliners will also plough into the ground…
Yeah, why do we bother training those pilots?
naaahahahahahahaha, best statement ever! i say to the comment above me
Soooo…..what you’re saying is that one day I’ll have to buy a new compass! Time to buy stock in companies that make compasses!
Great article. I didn’t expect doomsday but I have wondered what would happen when the polarity switched. Thanks.
Ah! The nutters are at it again.When they STOP, that’s when I’l start to worry!
I hate everything about 2012, the prdictions and so on. Expecially the rumours about planet x, named Nibiru. You really need to wisit http://2012-chat.com. They’re saying many things about this year, and they really need someone like you. Who can teach them. i.e. They’re all saying that Jupiter, which you can se now, is Nibiru!
And the worse thing is, that they believe in it. So show this contribution to them, so they can get more wiser.
I love your blog! Greetings from Sweden!
People should stop wasting their time reading doomsday scenarios and should start caring about how to save earth from global warming which has already shown its inpact on our daily lives.
“most likely experience aurorae at all latitudes”
One geomagnetic reversal please
Did doomsayers ever mention the disturbing influence of geomagnetic reversal on the global produktion of milk?
Proceedings of the National Academy of Sciences: Magnetic alignment in grazing and resting cattle and deer, http://www.pnas.org/content/early/2008/08/22/0803650105.abstract
“domestic cattle (n = 8,510 in 308 pastures) across the globe, and grazing and resting red and roe deer (n = 2,974 at 241 localities), align their body axes in roughly a north–south direction. Direct observations of roe deer revealed that animals orient their heads northward when grazing or resting.”
I predict that 12/21/2012 will mean the end of fall!
Geomagnetic reversal will give migratory birds a lot of trouble:
Do Birds Use Magnetic Field to Plan Migration Routes?, news.nationalgeographic.com/news/2001/11/1102_TVbirdflite.html
“A new study suggests that birds use the Earth’s magnetic field to plan dining locations along their migration route. These culinary stopovers are critical to the success of the migration because, according to a second study, the fatter the bird, the more efficiently it is able to fly.”
Why would satellites be affected by a magnetic shift? I thought their orbit was dependent on gravity.
A really fascinating article. Is the prediction of the End of Days a global phenomenon or is it just another Judeo-Christian myth? In reply to Todd’s article I would like to point out that “…chaotic only equals not knowing enough yet to make a good prediction…” is not scientifically accurate. Chaotic systems, and this may well be a chaotic system, are not open to prediction. We can see trends and large manifestations of chaotic systems, for example the cloud bands and spots of Jupiter but we cannot predict with any certainty what will happen in six months from now no matter how much data we possess.
“Without GPS, our airliners will also plough into the ground…” — Only if we migrate to pilotless airliners. Inertial navigation systems have been around for decades and are not dependent on compass information (Earth’s magnetic field) or GPS.
