The pole shift you are talking about is the magnetoc pole-reversal. All it will do is confuse animals that migrate, and make compasses point south,
not north.
I have no idea where you get the idea that a magnetic pole shift will cause rift valleys, or will cause tectonic plates to move, or for that matter,
effect the axis of tilt of the Earth. None of those things will happen. The magnetic shield around the Earth is mainly caused by the inner metallic
core of the Earth being 2/3rds of a second faster than the spin of the Earth. Maybes there is a chance that as the poles traverse from one end of
Earth to the other, the higher incidence of radiation that usually affects the poles will traverse through whichever route the poles take when they
change, but it shouldn't be a disaster.
The Earth flips it's poles fairly often. There's a branch of science called magnetology which studies the magnetism of the Earth, and it's history.
It was through the study of magnetism of the sea floor, near mid-ocean ridges, that scientists were able to confirm both the sea floor spreading
hypothesis, and plate tectonics. As basalt cools, it aligns with the magnetic field. These mid-ocean ridges are producing new land all the time, hence
the sea floor spreading. The ground is forced away from the mid-ocean rift, until it hits land, where it becomes a subduction zone, and it returns to
the mantle. This regeneration occurs at a pretty constant rate, and because of this, we are able to work out when the Earth had flipped it's poles in
the past. I believe (correct me if I'm wrong), they flip approx every 200,000 years. No one knows (except the OP) when the next one will come. It
could be 2 years from now, 20 years, 200, or even 2000 years from now. 2012 is total speculative BS.
That's some pretty bad science and fear-mongering you have there!
You might need to read up on geomagnetic reversal :
