The response to the changes in the orbital parameters is more dramatic: dependent if the orbital parameters correspond to the Eemian (a warm phase at around 125 kyr BP) or the one at 115 kyr BP (the onset of the last ice age), the simulation produces a warm state or the initiation of a cold climate. For the Eemian, the simulated climate agrees with the temperature distribution derived from pollen data. For the glacial inception, the model gradually builds up a large snow cover in the northern part of North America.
