Topic: The Magnetosphere, Global Warming and the Earths Core

I've been looking into climate change in relation to the North and South magnetic poles, I have wondered what will happen to the magnetosphere if the the Northern ice cap melts? The magnetosphere is apparently produced by the earths core and the main magnetic polarities feed out of the North and South magnetic poles, the ice cap acts as a barrier to magnetic and electric fields influencing their behavior - if the ice cap at the North pole melts, surely this will influence the magnetosphere and possibly even the core of the earth.

If magnetic and electric fields are able to traverse an area of open salty water the effects on the magnetosphere could be substantial maybe even causing the core of the earth to shift alignment and alter the magnetospheres properties around the planet.

I am still looking into concept this does anyone have any ideas?

I suspect larger forces are at work in pole reversals, larger and deeper. Ice doesn't much affect magnetic fields, I think. But I'm happy to entertain objections! (And remember, magnetic fields are incredibly weak, especially compared to gravity.)

By "shifting alignment" I meant changing the position although not radically enough to change polarity completely! Maybe just accelerating the North magnetic pole more to geographic North and altering the Magnetosphere's range and trajectory, like a contact lense the ice cap is thin and small but can influence the magnetosphere in general.

You heard it first folks!!(2012)
