My research group focuses on the dynamics of the climate system, with a specific emphasis on understanding the fundamental mechanisms that are involved in changes in climate. Climate models are powerful tools for learning about such mechanisms, as they enable us to test hypotheses about climate system behavior by performing controlled experiments. A substantial part of our research involves the simulation of past climates, such as the climate of the last ice age or the response of climate to changes in the earth's orbit. The value in studying past climates derives from the large changes in climate that have taken place over geologic time, which provide a framework for developing a better understanding of the key feedbacks and processes that determine how the climate system responds to external forcing.
