We thank Isaac Held for providing us with a version of the core GFDL spectral global model and discussions that helped clarify and focus this research. Bruce Wyman provided us with the AM2 GCM solutions for the sea ice and No–sea ice simulations and Peter Phillipps implemented changes to the spectral model. I would also like to extend my appreciation to Isaac Held and Kar Mac Chang for reviewing the manuscript. In addition, we also would like to thank Sara Mikaloff-Fletcher for editing and comments that help clarify the manuscript. The thorough review of three anonymous reviewers that helped enormously in clarifying the present revision is greatly appreciated.
