Figure 4: Precise anti-correlation between the millennial variability of the AM and the SAM.

From: Climate change patterns in Amazonia and biodiversity

(a) Northern Peru δ18O records from NAR (blue) and ELC (green) caves. (b) The AM δ18O record from Hulu cave15. The δ18O scale is reversed for the Hulu record (increasing down) as compared with Peruvian records (increasing up). The vertical bars depict H2 to H5. Numbers indicate Greenland interstadials. It is now evident that the SAM is precisely anti-phased with the AM in millennial variability, including YD, D/O H events.
