A coupled climate-ice sheet model is used in an attempt to simulate the N hemisphere ice-sheet volume variations implied by deep-sea core records over the last several 105 years. The lack of sea-ice variations causes the biggest departures from the GCM results. The two types of models produce similar ice-age simulations over the last 700 kyr in response to the orbital perturbations. In particular, fairly realistic simulations with strong 100kyr cycles similar to those obtained by adding an ice-calving mechanism to the ice-sheet model in Pollard (1982) are again produced in the coupled model. -from Author
