1998 Southern Magnetic Pole

2004 Southern Magnetic Pole

These two maps show how rapid, in 6 years time, the movement of the southern magnetosphere pole has become.

1994 Northern Magnetic Pole

2005 Northern Magnetic Pole

Now combine this movement with a volatile solar variation and add the possibility of a gradual pole reversal, which redirects the quantities of each type of charged particle, and you have exactly what you have described: A colder Antarctic and a warmer Arctic.

As the high energy particles flow along the magnetosphere down to the poles, distinguished by their charges, we can extrapolate where ice will melt and where it will refreeze.

It makes spectacular news to shout "a previously frozen ice shelf is now melting!"

But for those who embrace science rather than Chicken-Littleism, knowledge goes a long ways in explaining all such planetary changes.
