Abstract
We incorporate Milankovitch cycles into a recent conceptual climate model of the glacial-interglacial cycles. Investigated are the effects of orbital forcing elements such as variations in the eccentricity of the Earth’s orbit and variations in the obliquity of the Earth’s axis, on the expansion and retreat of stable ice sheets. The results showed that in a colder climate, variations in obliquity dominate the evolution of the ice sheet, whereas in a warmer climate, variations in eccentricity and obliquity both matter in the evolution of the ice sheet. The resulting simulations exhibited glacial cycles and also exhibited the skipped obliquity signal phenomenon.
