Simulation of the global coupled climate/ice sheet system over millennial timescales

Jeremy Fyke
Climate Modelling Group, University of Victoria

Motivated by the need to better understand interactions between large ice sheets and climate, I constructed and evaluated a new coupled ice sheet/climate model and used the model to explore aspects of past and future evolution of the ice sheet/climate system. I will first present main aspects of model design that went into coupling of the University of Victoria Earth System Climate Model (UVic ESCM) and the Penn State Ice Sheet Model (PSUI). I will then describe a primary set of experiments which analyzed sensitivity of the simulated Greenland Ice Sheet to important model parameters (particularly albedo and polar amplification), and a second set of simulations which explored the effect of Antarctic Ice Sheet retreat on global oceanography.
