If you still do not heard about it I am going to discuss about Earth's Pole Shift.
Earth has a magnetic field. This magnetic field is composed of two poles, the north pole and the south pole. If we say POLE SHIFT it is a reversal of Poles. Instead you see North Pole above the Earth, you will now see it below the earth. North Pole will be called South Pole same as South Pole will be called North Pole.
Magnetic field is a shield of the Earth against Sun's solar flares. Imagine the planets that do not have magnetic field such as mercury, venus, mars, etc. they look like a dessert. You cannot see living organisms in that particular planets. Earth would be like those planets if there would be no magnetic field.
We are hoping that this would not happen because this could create a huge devastating effect to earth in which billions of living things may die.
