Model the evolution of ice sheets such as Greenland and Antarctica. Understand the factors that control their evolution and and how they will contribute to sea level rise in the coming decades/centuries. This includes basal friction at the ice/bed interface, snow precipitation, temperature, etc.
Use the model to force changes in the Greenland and Antarctic ice sheets, and trace their contributions to sea level rise over decades and centuries. The changeable factors include snowfall, temperature, and friction between ice and Earth.
