Polar amplified warming across a wide range of CO2 in multiple versions of CAM

I will present results on the polar amplification (PA) in multiple versions of CESM in the slab ocean configuration. I will show PA across a wide range of surface warming and CO2 levels, with focus on any differences before and after the disappearing of sea ice. The simpler slab ocean configuration help us to focus on the atmospheric processes. Comparison with coupled model results will also be presented when possible.
