C.S.M.T., C.J.F., M.I.B., A.C., and N.R.G. are supported by their respective Australian Research Council (ARC) and Royal Society of New Zealand fellowships. Fieldwork was undertaken under ARC Linkage Project (LP120200724), supported by Linkage Partner Antarctic Logistics and Expeditions. J.W. and K.W. undertook GPR survey of the Patriot Hills record through the Natural Environment Research Council Project (NE/I027576/1) with logistic field support from the British Antarctic Survey. S.M.D. acknowledges financial support from Coleg Cymraeg Cenedlaethol, the European Research Council, and the Fulbright Commission (259253 and FP7/2007-2013). K.K. was supported by Japan Society for the Promotion of Science and the Ministry of Education, Culture, Sports, Science and Technology’s Grants-in-Aid for Scientific Research (15KK0027 and 17H06320). We thank Dr. Chris Hayward and Dr. Gwydion Jones for electron microprobe assistance; Kathryn Lacey and Gareth James for help with preparing the tephra samples; Drs. Nelia Dunbar, Nels Iverson, and Andrei Kurbatov for discussions on the tephra correlations; CSIRO GASLAB personnel for support of gas analysis; Prof. Bill Sturges and Dr. Sam Allin of the Centre for Ocean and Atmospheric Sciences (University of East Anglia, Norwich, UK) for performing the sulfur hexafluoride analyses; Levke Caesar (Potsdam Institute for Climate Impact Research) for preparing the recent trend in SSTs in Fig. 1; Vicki Taylor (British Ocean Sediment Core Research Facility, Southampton, UK) for assistance with marine core sampling; and Dr. Emilie Capron (British Antarctic Survey) for advice on reconstructing early southern LIG temperatures. We thank CSIRO’s contribution, which was supported in part by the Australian Climate Change Science Program, an Australian Government Initiative. We also acknowledge Johannes Sutter, Torsten Albrecht, and Jonathan Kingslake for advice and data on their model simulations. We also thank the editor and two anonymous reviewers for their insightful comments that helped improve this manuscript.
