If the Earth's magnetic field's are changing, then we might be subject to cosmic radiation in the future O.O
Maybe i'll get to be a X-Man, if it destroys my DNA
The magnetic field isn't "changing". The magnetic poles are continuing to shift, just as they have done forever. The shift is accelerating, which may or may not mean that they will reverse soon. No one knows what'll happen then, but the magnetic field will still be there as usual, and the magnetosphere will continue protecting the surface from radiation just as it's done for the last, oh, 3 billion years.
Ashamed of my own ignorance. Sorry.
