there was a nova (PBS) show recently about poles-->magnetism-->magnetic field-->atmosphere-->retained water connections.
and about all the various anomalies there now are on earth. its seemed to scientist as if we are nearing a change of pole period (nearing =2000 to 3000 years)

they wonder 1--how long will it take
2--what happens to earht atmosphere while its going on?

with out the strong influence of poles/magnetic field to deflect the solar wind, we will loose some of the atmosphere, and be bombared with ions, an other particles (now largle confined to the pole area's--aura borialis)


my other obsession
