(a) OCNM speleothem δ18O. (b) BCC speleothem δ18O. (c) Lake Jellybean sediment δ18O. (d) Lake Grinnell δ18O. Red and blue lines denote the records from western and eastern North America, respectively. The dashed lines show the mean values of each record for the MH and LH (for the demarcation of the MH and LH, see Supplementary Fig. 2).
