My thanks go to members of the climate modeling groups of both CSIRO Atmospheric Research and BMRC who contributed to the development of the GCMs analyzed here, and to those who performed the simulations, in particular Martin Dix (the C2 run) and Tony Hirst (C3). Helpful discussions with both Martin and Tony are acknowledged. The comments of two anonymous reviewers were also very helpful. This work contributes to the CSIRO Climate Change Research Program and is in part funded through Australia’s National Greenhouse Research Program.
