Yes, someone had posted a video that describes the earth crossing the galactic equator around or beginning in 2008. They associate crossing the galactic equator with a pole shift or magnetic disturbances, a debris field, etc.
From the mid-Atlantic rift zone records (5000 paleomagnetic earth scientists can't be wrong!), it would appear that the earth's magnetic field can die down within a scant 5000 years, and then start back up with reversed polarity. And the earth's magnetic field has decreased some 25% in the last 150 years since such measurements have been regularly taken.
I wouldn't worry about it, Obama has the answer, and Al Gore is his prophet.:)
