Some tout that magnetic pole reversal will bring about the end of the world.
How come the world's still here then? ;-)
That the Earth's magnetic field is diminishing and will be gone by 2500 AD is a scientific fact. That life on Earth cannot survive without the magnetic-field generated radiation belt surrounding our planet -- that's also fact.
That it's difficult to explain how life could have survived on Earth for billions of years while the magnetic pole has been oscillating through zero point thousands of times -- well, evolutionists will call you a creationist for asking such a question, so don't ask.
