The magnetic field does not just control our compass, it also acts as a protective barrier between us and some of the dangers of space, shielding us from radiation in the solar wind. The scary thing is that the Earth’s magnetic field has been steadily weakening over the past 180 years. A magnetic reversal is not just possible, it is destined to happen, its only a matter of when. Admittedly it could take hundreds or thousands of years, but one thing is sure, as the magnetic field has been weakening over the last 180 years, it has not been dropping at a steady rate, rather it has got more intense as time goes on. Already the changes are starting to effect our guidance systems in planes, but if an actual reversal happens it will cause an unknown amount of damage.
Polar shifts are infamous thanks to hollywoods films such as The Day after Tomorrow and 2012, but interesting enough there is another film called Knowing based upon the worlds destruction from something called a Solar Storm. A Solar storm is a burst of radiation and heat from the Sun which can reach as far as the Earth.
The issue I have is that next year in 2012, with a weakened magnetic field, a weakened protective barrier, combined with an expected solar storm, and none of this is made up, it is a real possibility for 2012 and nobody really knows whats going to happen! The Solar storm could worsen the magnetic field, it could knock out satellites and our communication systems, it could rupture volcanos and cause earthquakes. Are you prepared?
