Your government and religious leaders may not want you to know, but the evidence suggests that pole shifts are both magnetic and geophysical, with a periodic cycle of recurring and predictable cataclysms involving huge earthquakes and tsunamis, changes in latitude and altitude, mass extinctions, and the destruction of civilizations, reducing them to myth and legend. Evidence from geology, biology, astronomy, physics, history, mythology, religion and prophecy all suggests that the next pole shift is due in the 21st century.
