Studies of the duration and
stability of previous interglacials provide insight into recent climate
trends and the future of our current interglacial. Studies of the
last interglacial (Marine Isotope Stage 5; MIS 5) and an interglacial
~400,000 years ago (MIS 11) are especially relevant because they were
both relatively warm, yet characterized by different orbital
geometries. The orbital geometry of MIS 11 was most like the
current interglacial, and many consider it the best analogue of the
Our work suggests that peak
warmth of last interglacial was shorter than previously thought and
demonstrate a close association between modest ice rafting, cooling,
and deep ocean circulation even during the peak of the interglacial and
in the earliest stages of ice growth.
