δD (deuterium/hydrogen) ratio records of air temperatures over Antarctica (Jouzel et al., 2003). δD levels have remained more constant during the Holocene (MIS 1) than during most other interglacial periods. Orbital forcing during MIS 19 (ca. 790–760 ka) was the most similar to the Holocene's, and MIS 15 (ca. 620–560 ka) has the most similar pattern of deuterium concentration, so it would be of interest to know what was happening to megafaunal species during these two interglacials (redrawn from Ruddiman et al., 2016).
