1. 1 Response of Australian Temperature Extremes to Climate Variability and Change Regional Climate Research Section NCAR Earth System Laboratory NCAR is Sponsored by NSF and this work is partially supported by the Willis Research Network, the DOE Research Program to Secure Energy for America and NSF EASM Grants 1048841 and 1048829 Greg Holland Collaboration with Cindy Bruyere Mari Jones and Abby Jaye Holland CSU Workshop 0114

2. Working Hypothesis: o Global temperature extremes change slowly- if at all – under GW o Maxima from advection increase substantially. The Record Australian Summer 2013 Holland CSU Workshop 0114 2 Summary
