The recent media attention to sunspot activity (however warranted) reminds me of a question I had long ago. Given the angular momentum and the slight 'wobble' of the earth, and remembering the apparently sporadic distribution of 'polar inversions' observed by geologists, I'm wondering how much the sun's magnetic field, and by extension the background galactic magnetic bias, could be influencing tidal, climate, tectonic and other terrestrial forces. It appears to me all the earth would need is a small 'nudge' and it's existing angular momentum would send it toppling end-over end, and we're so small compared to the sun so it SEEMS feasible to me. I'm sure that human observers would have noticed, but actual recorded history often proves to be rather incredulous and untrustworthy. Often attempts at truth or science are buried by popular opinion, and astronomical data goes back only so far . . .
Anyway, how likely is it the ice ages could be explained by the Earth 'realigning' so that polar regions would migrate over the surface of the earth?
In this model, rather than the entire earth being perfectly static and climate changing during recurrent ice ages, the data might be interpreted as more 'localized' disparages in temperature, with global averages remaining more or less constant and the earth's rotation causing the polar caps to 'migrate' across the surface. Can data disprove this? Is it POSSIBLE or is there some greater force I'm not considering which would keep the earth's wobble from becoming a topple?
