Here is a very clear explanation of the flip flop in the solar magnetic field every 11 yeas and why the Mayan calendar calls for a flip flop in 2012 of the Earth's magnetic field. That this may be a significant event this year is still anyone's guess. That the sun's magnetic field will flip this year is pretty well a certainty. Do you know why?
