Figure F1. A. Previously published data on relative sea level from 20 cal y BP through present (upper symbols) plotted with GISP2 δ18O (proxy for temperature over Greenland; black line). Meltwater pulse 1A (MWP-1A) refers to an interval of particularly rapid sea level rise during the last deglaciation. MWP-1B = meltwater pulse 1B, LGM = last glacial maximum, B/A = Bølling-Allerød, and YD = Younger Dryas. Source of data: Tahiti = Bard et al. (1996, 2010); Huon Peninsula = Chappell and Polach (1991), Edwards et al. (1993); Huon drill core = Cutler et al. (2003); Sunda shelf = Hanebuth et al. (2000); Barbados = Fairbanks (1989), Bard et al. (1990); GISP2 = Stuiver and Grootes (2000). B. Planktonic foraminiferal Mg/Ca records of sea-surface temperature (SST) in the western sector of the Western Pacific Warm Pool (WPWP). Comparison of Indonesian and WPWP Globigerinoides ruber Mg/Ca-based SST anomaly records modified from Linsley et al. (2010). Anomalies calculated as departures relative to average of last 2000 y. Data shown are 200 y nonoverlapping binned averages of eight cores throughout the western sector of the WPWP (black) and averages of only four southern Makassar region cores (green). Orange SST data are from Oppo et al. (2009) for only the southern Makassar Strait. Light green and dashed bounding lines show the standard error (SE) of all measurements in each 200 y bin. The LGM, Holocene Climatic Optimum, and Medieval Warm Period (MWP) are indicated. Composite reconstruction indicates that SSTs in this broad region of the WPWP warmed ~3°C after the LGM and reached a maximum 0.5°C higher than in preindustrial times from ~10,000 to 7,000 cal y BP during the Holocene Climatic Optimum.
