It's moved many times in the past on a cyclical basis. It's one of the drivers of the ice ages and Northern Africa had been flip flopping between desert and lush wet lands over the last few million years. Pretty sure we didn't have much to with that.I watched a docu that said the stream is moving regardless of global warming seemed pretty convincing...
if the poles flip they will blame global warming too, if the moon pulls stronger on the tides, global warming.
just the leap to answer for all our problems these days
