However, its not all good news. Until recently, it was thought that
pole shifts were a gradual process. But recent evidence from studying
the alignment of iron particles in lava flows found one case where the
Earth's magnetic field shifted 80 degrees in 13 days.
What would a pole shift do to life on Earth?
Migratory birds, fish and animals would become confused. This might
lead to them wandering far from current feeding and breeding grounds,
into areas not suitable for them, and could quite easily be concieved
as leading to mass extinctions, habitat destruction and loss of life,
both animal and human.
While this latter theory is controversial, scientists have already
shown that insects can actually be killed as a result of fluctuations
in magnetic fields around them, and the same experimenters have shown
similar, though smaller, effects in humans, leaving them dazed and
confused.

So were any of these birds that died recently found where they weren't supposed to be?
It's also discussing pole reversal, not mere shifting.
edit on 6/1/11 by Chadwickus because: (no reason given)
The core is pivotal to everything. The core is what science thinks is gravity. The core is what's keeping us earthbound and animals on track. Not gravity.
That's why you can't stand on the Moon. There's no core (most likely artificial). It's not that it lacks gravity.
And as soon as we ALL figure that out, the sooner we can graduate from this galactic kindergarten classroom.

Compasses would obviously be effected as would all navigational instruments which depend on them. So shipping, air-flight and all GPS equipment, including satellites, would be off-line until we figured out how to cope with the reversal.

No I believe he was just making a statement that there is evidence that the earth's magnetic field has shifted 80 degrees in 13 days before...
"Science" has pretty much contributed gravity to the mass of an object...not what's inside it. The moon does have gravity, only 1/6 of what's found on this planet due to it's mass being proportionally less.
Mock science all you want, it really only serves to make you look more ignorant.
Earth is like a giant magnet with a North and South Pole. However, the magnetic North and South Pole are not aligned with the Geographic North and South Pole. The Geographic North Pole is defined by the latitude 90° N and is the axis of the Earth's rotation. The Magnetic North Pole is where the Earth's magnetic field points vertically downward. The Earth creates its own magnetic field from the electric currents created in the liquid iron-nickel core. In order to illustrate the earth's magnetic field, three datasets for Earth's Magnetism have been created. All of these datasets show the changes in the magnetic field from 1590 - 2010. The first dataset shows the magnetic field lines at the surface of the Earth. The magnetic poles are indicated by stars. The blue lines show where the magnetic field dips into the Earth and the red lines show where the magnetic field emerges from the Earth. Where the field lines are horizontal to the Earth, between the red and blue lines, is the magnetic equator shaded yellow.
Compass needles point in the direction of the magnetic field lines, which is generally different from the direction to the Geographic North Pole. The compass pointing direction can also differ from the direction to the Magnetic North Pole since the magnetic field lines are not just circles connecting the magnetic poles. The second dataset shows the compass pointing directions around the world. The black lines (meridians) indicate the direction of True North. The angle between the compass pointing direction and True North is called magnetic declination. The third dataset shows lines of equal magnetic declination measured in degrees east (positive) or west (negative) of True North. The black line is where the declination equals zero and the direction of True North and Magnetic North are equal. The Magnetic North and South Poles are indicated by the black stars. It is important to know the magnetic declination when using a compass to navigate so that the direction of True North can be determined. Since the 1970's the movement of the Magnetic North Pole has accelerated.

Absolutely nothing to worry about read my post a couple above.
