Rather than an extreme fluctuation in obliquity through to a modest present 25 degrees, and a dramatic, virtually global ice sheet 4 billion ago, receding to a more modest northern cap between 5 and 3.5 million years ago, the positioning of the water-ice in my contraction model suggests less extreme fluctuations in obliquity and less severe ice coverage but a consistent movement of the crust out of the polar regions into more equatorial latitudes. This suggests that the reason for the presence of water-ice in mid-latitudes and even at the equator, from the phyllocian era and the turn of the Theikian era, is because those areas of crust used to lie within the polar region.
