The Big 4: Records of Worldwide Stage 4 Glacial, Climatic, and Environmental Changes Posters


Submit an Abstract to this Session


Session ID#: 49923

Session Description:
Marine Isotope Stage (MIS) 4 may have been more extreme (“glacial-like”) than MIS 2, including during the global Last Glacial Maximum. To what extent this statement might be true depends on the climatic parameter and region of interest. Mounting evidence from a range of archives - for example glacial extent and surface ocean temperatures in the Southern Hemisphere - suggests that conditions during MIS 4 may actually have been more severe (e.g., colder) than the more universally accepted glacial maximum of MIS 2, suggesting that much of our long-held understanding of glacial development may require reevaluation. In this session we welcome contributions that contribute toward improving our understanding of MIS 4 glaciation, climate, and ocean circulation. Research may include, but is not limited to, climate proxies, greenhouse gasses, sea level, circulation change, glacier extents, chronologies, and modeling.
