Cave stalagmite δ18O records of the (B) Furong (this study), (C) Hulu (blue)9, Sanbao (green)29, and Dongge (purple) caves30. 230Th ages and errors are color-coded below the stalagmite records. (D) Global 64 (blue) and Red Sea65 (red) sea level records. The Arabic numerals 1–8 represent the Greenland Interstadials (GIS). Younger Dryas (YD), Older Dryas (OD), and Heinrich events 2–4 (H2–H4), are shown; the gray columns denote the YD, OD, and H2–H4, respectively. H1 is highlighted by a yellow column. The light gray column shows a δ18O excursion in FR5 records, which is not seen in the Hulu record. The gray curve denotes the northern hemisphere summer insolation (NHSI) at 30° N (W/m2)66.
