The evolution of past global ice sheets is highly uncertain. This paper presents PaleoMIST 1.0, a global ice sheet reconstruction for the past 80,000 years, constructed independently of far-field sea level and δ¹⁸O proxy records. The reconstruction resolves the "missing ice" problem during the Last Glacial Maximum (LGM) by being compatible with LGM far-field sea-level records without requiring extra ice volume. However, it does not match proxy-based sea level reconstructions for Marine Isotope Stage 3 (MIS 3), suggesting a more complex relationship between marine δ¹⁸O and sea level than previously assumed.
