basis: Steig et al. 2013 suppl: Scaling between I´18O and temperature in West Antarctica can be estimated in a number of ways, all yielding similar results. The local interannual scaling between WAIS Divide I´18O and Byrd temperature is 0.5a€°/A°C; the ratio of 50-year trends also yields 0.5a€°/A°C (1957-2006, Byrd temperature trend7 = 0.48A°C/decade; WAIS Divide I´18O trend = 0.24a€°/decade). Regional interannual scaling between the composite I´18O series in Figure 1 and the West-Antarctic average temperature from Steig et al.4 is also 0.5a€°/A°C; the ratio of 50-year trends is 0.6a€°/A°C (1957-2006, West Antarctic temperature trend = 0.19A°C/decade4; composite I´18O trend = 0.12a€°/decade). Comparison betweenI´18O and the borehole temperature reconstruction from WAIS Divide6 over the last 2000 years also results in similar scaling. See also Kuttel et al, 2012 for more interpretation
