Coral Li/Mg results compared to ice core data. (A) Greenland and (B) Antarctic ice core stable isotope records of deglacial temperature change (stacked stable isotopes1,2,63). (C) Antarctic ice core atmospheric CO2 record64. New deglacial cold-water Li/Mg temperature records from (D) East Equatorial Pacific and Equatorial Atlantic, (E) Burdwood Bank (AAIW), (F) Cape Horn (UCDW), and (G) Sars/Interim sites (UCDW and LCDW). The Younger Dryas and Henrich Stadial 1 are highlighted by grey bars. Replicate measurements (open symbols) agree well within coral specimens; the majority yielding seawater temperature values within 2 °C of each other. Replicate averages shown as filled symbols. Error bars denote 2σ age uncertainties. Analytical error is smaller than the markers shown.
