Accurately dated Antarctic ice-core records and the comparison with sea level proxies (Kawamura et al., 2007^[1]). A) Orbital tuning of O2/N2 in the Dome Fuji core (red) and Vostok core (orange) with local summer insolation (SI; blue). B) Tuning tie points with 2σ error bars due to the noise of the O2/N2 data. C) 2σ dating uncertainty by combining those of the tie points and interpolation procedure. D) Dome Fuji temperature (red), Vostok temperature (orange), Northern Hemisphere summer insolation (SI; blue) and obliquity (gray). E) CO2 concentration from the Dome Fuji core by wet extraction (black) and dry extraction (purple). Note that the wet values are too high in LGM and dry values are too low in MIS 3 due to artifacts during extractions. F) Sea level reconstructions using radiometrically dated corals blue; (Thompson and Goldstein, 2005^[2]), and orbitally tuned δ18O of seawater based on marine sediment records through ice sheet modelling blue solid; (Bintanja et al., 2005^[3]) and regression analyses blue dashed; (Waelbroeck et al., 2002^[4]). Note they are plotted on their own chronologies.
