The glacial-interglacial changes observed in Paleoclimatic data of the Middle and Late Pleistocene periods are analyzed in terms of two generalized stochastic resonance models including memory effects. The simple models account for the asymmetric, saw-tooth shaped temperature oscillations occurring both at Milankovitch (~100kyr) and millennial time scales.
