Solar Flares
Poles and Flares

Some people connect geomagnetic reversal and solar flares in an ultimate doomsday scenario, claiming that a giant hole left in the atmosphere from the reversal of the magnetic poles will allow devastating solar flares to reach the Earth.

Another phenomenon some people worry about is space weather and solar activity. The fear is that, in 2012, the sun will reach the peak of an 11-year cycle known as solar maximum. When it does reach this peak on or around Dec. 21, 2012, the sun will unleash giant solar flares toward the Earth, causing unparalleled havoc.

This scenario is very similar to the previous one involving geomagnetic reversal, in that both pole shifts and solar activity occur at fairly regular intervals. Solar flares will likely happen sometime between 2012 and 2014, but they've been happening for years and years, and the worst they can do is interrupt satellite communications.
