Short summary
The El Niño–Southern Oscillation (ENSO) and Southern Annular Mode (SAM) are two important modes of climate variability, strongly influencing climate across the tropics and Southern Hemisphere mid- to high latitudes. This study sheds light on their relationship over the past millennium, combining evidence from palaeoclimate proxy archives and climate models. We show that their indices were mostly negatively correlated with fluctuations likely driven by internal variability in the climate system.
