Recent observations have revealed that the fastest melting rate of polar ice sheets ever observed is ongoing and there is growing concern of significant rise of sea level in the future. Geological records have suggested that abrupt rises in sea level (6-9 m rise) happened during the Last Interglacial when global mean sea surface temperature was slightly higher than the preindustrial level. If this were really happening, there is a critical ice sheet stability threshold resulting in the catastrophic collapse of polar ice sheets and substantial rapid sea-level rise in the interglacial climate regime. Given that the current global mean SST has already reached the Last Interglacial level, it is urgent issue to evaluate whether massive collapse of the Antarctic ice sheets could occur in the future. In this article, we review climate state, sea level fluctuation and stability of Antarctic ice sheet in the Last Interglacial.
