Antarctic moisture research will model ice sheet formation in ancient warm periods
Los Angeles CA (SPX) Oct 31, 2025 Researchers from Binghamton University will investigate how increased moisture transport during ancient warm climates contributed to the growth of Antarctic ice sheets. This work, funded by the National Science Foundation's P4Climate award, aims to clarify how future sea level trends might be affected by similar processes. The study targets the Miocene Climatic Optimum, which occurred approximately 17 to 14.7 million years ago, when atmospheric carbon dioxide concentrations surpassed 500 parts per ... read more |
