Experiments in Milankovich cycles


The idea of Milankovich cycles is that the tilt(obliquity) of the Earth and the orbit of the Earth influence the climate. The astronomical data have been calculated by celestial mechanics for the last 50 million years. The exact relationship between the astronomical forcing and the climate is unknown, but there are various models for this.

On this page we collect links to Sage worksheets related to these models.

List of sheets

A classical model is due to Imbrie and Imbrie.

A model incorporating the level of CO 2CO_2 in the atmosphere, the salinity of the deep ocean and the volume of the ice sheets is due to Paillard and Parrenin
