It happen before, it will happen again. It also happen while humans were on this planet, so basically it won't be so bad if we prepare for it. Harden our infrastructures to electromagnetic pulse that will be generated by the pole reversal and we will be fine. Of course we got to compensate for the mix-up of the weather that will happen on the planet.

Not really, the only thing we would notice is that our magnetic compass shows in the wrong direction. It would be worse if the magnetic field collapsed.
That would be bad, very bad... magnetic field collapse that protects us from the bombardment of particle rays from the sun. We would end up being stripped of our atmosphere and well... kiss our planet goodbye!
