They note a period of low eccentricity centered around an very rapid advance of the ice sheets in Antarctica where they went from 50 % today's size to 25 % larger. (theinconvenientskeptic.com)
Our orbital fits also favor low eccentricities, consistent with predictions from dynamical modeling. (arxiv.org)
I am assuming the similarity of the «low eccentricity and consequently weak precessional forcing» in the current interglacial and during MIS 11. (realclimate.org)
