This multidisciplinary session will bring together research focused on understanding the nature, properties, and spatiotemporal patterns of Warm Intervals in the Southern Hemisphere during the Quaternary. Understanding the controls on, and characteristics of, warm phases is important in the light of present anthropogenic climate change. Warm intervals during the Quaternary are known to have varied in length, spatial scale, and magnitude, and ranged from warm marine isotope stages through to shorter-lived phases associated with ocean-atmosphere variability. This session aims to showcase new multiproxy and modelling studies of climatic variability in the period MIS 5 to 1 which provide insight into the timing, spatiotemporal extent, termination and forcing responses during warm periods in the Southern Hemisphere. Contributions of multiproxy studies from terrestrial or marine archives that characterise the anatomy of warm periods are welcome.
