NASA's confirmed 2012 prediction - Deterioration of Earth's Magnetosphere during Sun's Polar shift in 2012 :

Scientists
have now accepted that the intersection of 2 problems - the
deterioration of Earth's Magnetosphere during the Sun's Polar shift in
2012 (as recently discussed) will be the real concern as we approach
2012 :

Now here's the reason why: 

Scientists
have found two large leaks in Earth's magnetosphere, the region around
our planet that shields us from severe solar storms. Now in 2012 the suns poles will reverse (not the earths as wrongly said on many 2012 sites - see below!) , during this time a massive solar storm will reck havoc
on earth - usually this is no problem - but now due to the 'cracks' in
it, Earth's protective Magnetosphere may fail us,  so the
violent solar and electromagnetic radiation will make it through and
cause many problems to life as we know it (eg: disabling communication satellites, mobile phones, effective sleep patterns,  & radiation poisoning

of humans) Also as earth has to absorb extra radiation & energy
this will cause possible changes within the earth's core - with energy
being re-dissipated from the earth with new volcanoes formed and crust movement.

As mentioned in the Video below -
The leaks are defying many of scientists' previous ideas on how the
interaction between Earth's magnetosphere and solar wind occurs: The leaks are in an unexpected location, let in solar particles in faster than expected and the whole interaction works in a manner that is completely the opposite of what scientists had thought:

Important Note:  many websites say Earths Poles will shift during 2012 but this is not true. According to NASA, Planet pole reversals (not suns - which like ours can reverse poles quickly in a few years)  take a few thousand years to complete, and during that time--contrary to popular belief--the magnetic field does not vanish - "It just gets more complicated"  -so this is probably why our  Magnetosphere is going weird at the moment. (Another controversial idea is that the Earth's magnetosphere could be
influenced temporarily by our current position in the solar system in
the Milky way as we past by a big black hole, however theories of the
2012 galactic plane alignment are heavy disputed at the moment )  -
Either way

its true that Earths Magnetosphere is very weak at the moment and
yes this is a sign of initial pole shifting but not complete pole
reversal of Earth - this won't happen in 2012 as its a slow process and
is predicted to take another 1200 years to complete. What is of major
concern overall is how strong the Magnetosphere will be during the solar storms of 2012.

NASA Extends mission - worried about 2012?
On May 19, 2008 the Space Sciences Laboratory at Berkeley announced NASA had extended theTHEMIS mission to the year 2012 (strange co-incidence right?). In addition a new mission that would send twoTHEMIS probes into lunar orbits was provisionally approved by NASA, pending a technical review before February 2009
