Fig. 5. Spatial-temporal comparison of speleothem δ¹⁸O records from the SEY, Dongge (2) and Sanbao (1) caves in southern China during MIS 5.

The summer (21 July) insolation at 65°N (the gray curve) is also plotted for comparison. To facilitate the comparison, we aligned the speleothem δ¹⁸O values during MIS 5c with the insolation peak. The dashed lines, drawn from the MIS 5c insolation peak, indicate the difference among the three records in their amplitudes of δ¹⁸O minima during MIS 5.
