2009年8月7日 · The Last Glacial Maximum (LGM) is conventionally defined from sea-level records as the most recent interval in Earth history when global ice sheets reached their maximum integrated volume . Because sea level is an integrated signal, however, it does not distinguish between globally synchronous ice-sheet maxima that may have been in equilibrium ...
