I had read about the magnetic poles reversing years ago. The field itself is not fixed and about every 450,000 years or so, the poles actually reverse. This puts the magnetic North where the South was.I'm sure a lot of you remember that. NOW .. it's being caused by climate change. You can't make this stuff up (unless you're a liberal)From now on, if someone farts..don't blame it on the dog. Just say it was caused by climate change.
