Exploring a simple model for Pleistocene glacial variability

Abstract

We explore a simple model of Huybers that attempts to justify the hypothesis that obliquity paced glacial cycles throughout the Pleistocene. We find that, for some fixed parameters, the model has a small number of trajectories over all initial conditions. We also test the predictability of the model after adding noise. We then compare these findings with those of another well-known model for Pleistocene glacial variability.
