Supplemental Information | STUDY NOTES: Please contact principle investigator Brian Chase to obtain these data. Stable nitrogen (d15N) and carbon (d13C) isotope data obtained from the De Rif rock hyrax (Procavia capensis) midden in the Cederberg Mountains of South Africa's Western Cape. d15N is interpreted as a proxy for aridity, with higher values reflecting an enrichment of 15N in soils under drier conditions ABSTRACT SUPPLIED BY ORIGINATOR: Climate change during the last deglaciation was strongly influenced by the 'bipolar seesaw', producing antiphase climate responses between the North and South Atlantic. However, mounting evidence demands refinements of this model, with the occurrence of abrupt events in southern low to mid latitudes occurring in-phase with North Atlantic climate. Improved constraints on the north-south phasing and spatial extent of these events are therefore critical to understanding the mechanisms that propagate abrupt events within the climate system. We present a 19,400 year multi-proxy record of climate change obtained from a rock hyrax midden in southernmost Africa. Arid anomalies in phase with the Younger Dryas and 8.2 ka events are apparent, indicating a clear shift in the influence of the bipolar seesaw, which diminished as the Earth warmed, and was succeeded after ~14.6 ka by the emergence of a dominant interhemispheric atmospheric teleconnection. |
