The 2012 Doomsday Prediction.

The 2012 Doomsday prediction is based on the end of the Mayan Long Count calendar. "The Twelfth Planet” this book was published in 1976. He has found and translated Sumerian documents that identify the planet called Nibiru, orbiting the Sun every 3600 years. These Sumerian fables include stories of “ancient astronauts” visiting Earth from a civilization of aliens called the Anunnaki. And the Nancy Lieder a self-declared psychic who claims she is channeling aliens, wrote on her website Zetatalk that the inhabitants of a fictional planet around the star Zeta Reticuli warned her that the Earth was in danger from Planet X. Only recently have these two fables been linked to the end of the Mayan long-count at the winter solstice in 2012  hence the predicted doomsday date of December 21, 2012.

There are slow movements of the continents the Antarctica was near the equator hundreds of millions of year’s ago. But that is irrelevant to claims of reversal of the rotational poles. So many of the disaster websites pull a bait-and-shift to fool people. And they claim a relationship between the rotation and the magnetic polarity of Earth, which does change irregularly with a magnetic reversal taking place every 400,000 years on average. 

Magnetic reversal doesn’t cause any harm to life on Earth. This magnetic reversal is very unlikely to happen in the next few millennia, anyway. But they falsely claim that a magnetic reversal is coming soon in 2012 and that this is the same as, or will trigger a reversal of rotational poles.
