南极西部冰盖（WAIS）的冰川消退历史为它的未来提供了线索。向南的接地线迁移的日期过去三个地点在罗斯海湾。结果表明，大多数衰退发生在中晚全新世在没有实质性的海平面或气候强迫。目前的地面线后退可能反映了自全新世早期以来一直在进行的冰衰退。如果是这样的话，即使没有进一步的外部强迫，WAIS也会继续后退。
The history of deglaciation of the West Antarctic Ice Sheet (WAIS) gives clues about its future. Southward grounding-line migration was dated past three Locations in the Ross Sea Embayment. Results indicate that most recession occurred during the middle to Late Holocene in the absence of substantial sea Level or climate forcing. Current grounding-line retreat may reflect ongoing ice recession that has been under way since the early Holocene. If so, the WAIS could continue to retreat even in the absence of further external forcing.
