Twenty degrees north-by-northeast

[Ens Entium]

Well if by solar elliptic you mean the 'circle' along which the planet revolves around the sun, then if you take a line perpendicular to that, the earth's axis of rotation is at about 23 or so degrees away from that perpendicular.

So if the axis aligns with that elliptic, the north pole would have permanent summer, there'd only be one season, on one side of the planet. You see the earth's rotation would never expose a different side to the sun.

I wonder if it means that we're moving closer to the perpendicular. So we'd have less extreme seasons.

Given your post, with the academic papers, in another thread it seems the magnetic alignment is secondary. Although one could always question the assumption they made that the rotation of the core aligns itself at the outer surface with the mantle.

Thanks though.
