Mitch Battros recently published an article about Magnetic Pole Reversals and Possible Crustal Displacement in his e-newsletter, "Earth Changes Media."
He says here is a debate if Earth has experienced a severe tilt in its past - perhaps up to 90° which goes far beyond a better known tilt called "Earth's precession". Sometimes referred to as 'precession of the equinoxes', rotation of the Earth's axis which shifts between a tilt of 22.1° and 24.5° and back again, taking approximately 41,000 years to complete a full rotation.
Currently, the Earth's tilt is at 23.44° which is roughly halfway between its extreme values.
Scientists have found evidence that the Earth might have actually rolled several degrees in the past, completely shifting continents i.e. Canada in the southern hemisphere.
Hard scientific evidence has come forth confirming Earth's magnetic field is weakening. This is important for two reasons. 1) A weakened magnetic field allows charged particle events such as solar flares, coronal mass ejections (CME), coronal hole filament, gamma rays, and galactic cosmic rays to produce enhanced consequences to extreme weather events which includes earthquakes, volcanoes, hurricanes, tornadoes etc.
2) The second major consequence of a weakened magnetic field is its identification as the 'precursor' to a magnetic pole shift. It is estimated that Earth's magnetic field reverses every few thousand years at low latitudes and every 10,000 years at high latitudes. It is believed we are far enough along the cycle that many living today will witness the bouncing back and forth of magnetic north and it swings reaching latitudes below 30°. Magnetic north can also move east and west longitudes.
historical magnetic field reversals indicate during the period of Earth's magnetic field reduction will be in flux for several years before a full magnetic flip will incur.
