We all know Magnetic North shifts yearly, but if this story is correct, it looks like it's shifting at a much greater rate then normal 40 miles a year towards Russia. At this rate, this can have drastic implications for aviation. (Among other things) An example of which in this story is a Tampa runway had to be closed until Jan 13, until NAV charts could be updated, and runway and taxi signs and marking are changed.http://news.yahoo.com/s/yblog_thelookout/20110107/sc_yblog_thelookout/florida-temporarily-closes-runway-due-to-magnetic-pole-shifting
