The Milankovitch cycle is repeatable and tied to solar orbital cycles. Haiving a 12C swig in temperature is a great deal more than what has happened in modern times. Sea levels can also vary by +/- 10's of meters, not a few inches per century like the curve we are on now. CLiamte varies a lot and it behooves us to understand the cycles that drive this variation.
