H: Stacked composite δ18O data of Greenland ice cores (Dye3, GRIP, GISP2, and NGRIP; resolution of ~2.5 years in gray and four-point average in red; Thomas et al., 2007). The δ18O scales are reversed for Asian Monsoon (AM) records (Dongge, Qunf, and Hoti Caves, increasing down) as compared with South American Summer Monsoon (SASM) records from Padre and Paixão Caves. Three arrows depict anti-phased changes between AM and SASM and changes in Greenland temperature. Color-coded error bars indicate typical dating errors (2σ) for each record around 8.2 kyr B.P. event. Dashed gray curve of Q5 record was redated and plotted with previous δ18O record on distance scale (blue curve; Fleitmann et al., 2003), which generally matches the redated chronology due to nearly linear growth around 8.2 kyr B.P. event (Fig. DR2C). Yellow bar indicates central 8.2 kyr B.P. event in Greenland, and green bar indicates second event following central event (Thomas et al., 2007). AM records of 8.2 kyr B.P. event are broadly similar with each other and antiphased to SASM variations. Structure of double-plunging AM or double-peaked SASM is consistent with double temperature plunges over Greenland. VSMOW—Vienna standard mean ocean water; VPDB—Vienna Peedee belemnite.]()
