The weather cares about which direction the (weak) magnetic field lines of the earth are pointing?
Color me skeptical.
This sounds like Al Gore science.
Given that we don’t know what causes Ice Ages, this sounds as likely as other explanations. One image that remains with me is what I saw in a documentary at the McDonald’s Observatory. The earth is shown as a small rock in a fiery stream of solar radiation. It is a small blue stone that is kept from burning to a cinder (like our moon) by the magnetic field that surrounds it. Compared with the forces at work as depicted in that film, the acts of man seem trivial.

Where are the largest deposits of ice on the earth? The poles. If the poles move then the weather that deposits the ice and snow must be in some way affected.
Seems logical to me.
It was hypothesized that increased levels of incoming cosmic ray particles would in turn result in the formation of more water clouds. The cosmic ray influx in turn was expected to be influenced by such things as the earth’s own magnetic field and streams of charged particles coming from sunspots. The last I heard in this argument was that there was an attempt to empirically correlate cloud cover with cosmic ray influx and it found nothing.
