I read in a science magazine several years ago that some scientists believe that the last ice age was brought on by a shift in the magnetic poles.
Well, according to this article, the last pole shift was 780,000 years ago, which would invalidate that theory...
But it also says there is supposed to be a shift every 300,000 years or so, and that we're way overdue...
Mother nature must be in a tizzy..
She's "late"...
