I'm not saying for one minute that Milankovitch's cycles are why we are, currently seeing global rise in temperature, I just though it added another spin on things and to show "Global warming" is definitely not just down to Human activity in the last 100 years or so of accelerated industrial activity.
Cows have a lot to answer for as well.
Quite right. Most people will have seen Milankovitch cycles as picked out by the regualr bands of flint you can see throughout the faces of the white cliffs of southern England.
