While the poles are shifting, the Earth would have no shield against harmful gamma rays,and as a result all life would end.
I think you are getting a little mixed up. Nothing like mass extinction will happen with Magnetic Polar Shift.
Now if you were talking about Geographic Polar Shift, then most probably, because of something catastrophic happening to knock the Earth's Axis of Rotation out of line, would cause mass extinction.

∙ 13y agoVery little. Many people mistakenly think that the magnetic field protects the surface from cosmic rays, but it is mostly the atmosphere that does that. When the field switches, the magnetic field gets very low, and intense cosmic rays reach the top of the atmosphere (instead of being deflected by the magnetism), but only a few percent increase is measured at the Earth's surface. (At the North Magnetic Pole there is never any shielding, and that is how much stronger the surface cosmic rays are.) Some birds and protozoa that use the magnetic field for navigation would be disoriented. And our compasses would be useless until the field settled down in its reverse direction. The last recorded switch was about 790,000 years ago.

Does the earth spin on its true poles or magnetic poles?
Magnetic poles
True or false the magnetic poles are not located exactly at the geographic poles?
True. The magnetic poles move constantly.
What are the three magnetic poles?
The Geographical South Pole, The Magnetic South Pole and The Southern Pole of Inaccessibility.
What is true about earths poles?
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.
Is the magnetic field of earth stronger near the equator of near the south pole?
The magnetic field is stronger at the poles.
Did the shift take place on 21.12.2012?
No, the shift of the Poles (even the magnetic Poles) did not take place on 12dec12.
What is polar wondering?
magnetic poles constantly shift relative to the axis of the rotation
Does the earth spin on its true poles or magnetic poles?
Magnetic poles
What is it called when earths magnetic poles change poles?
This is known as magnetic reversal when earth's magnetic poles change places.
Do magnetic poles that are alike attract?
alike magnetic poles do not attract because according to the law of magnetism, it is stated that unlike magnetic poles attract and alike poles repel.
Is there any possibility that poleshift wont have any effect on earth?
If the magnetic poles shift that means that the Earth has been affected. If there are other effects that are a result of the magnetic pole shift is a matter of debate (mostly how quickly the shift takes place). If the Earth is without a magnetic field for some time ( I do not know the time frame days weeks years decades or millenia) then some things will be affected as the magnetic field channels charged particles towards the poles and keeps the Van Allen belts in place.
True or false the magnetic poles are not located exactly at the geographic poles?
True. The magnetic poles move constantly.
What is it called when Earth's magnetic poles chang places?
This is known as magnetic reversal when earth's magnetic poles change places.
What are the three magnetic poles?
The Geographical South Pole, The Magnetic South Pole and The Southern Pole of Inaccessibility.
Where are the magnetic forces the strongest?
magnetic poles
What statement is true about Earth's poles?
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.
Do moons have magnetic poles?
No. No moon has strong magnetic fields that result in "poles" like Earth ... but they often do have weak magnetic fields.
