The response of the world's largest ice mass to climate change is important because melting leads to a rise in sea level. Our ability to predict changes in ice volume and sea level under a warming climate, will be enhanced by better understanding of past ice sheet responses to changes in atmospheric carbon dioxide. Improved numerical models now exist that allow realistic simulations of Antarctic ice. These models will be developed further and constrained against existing and new field evidence for the Last Glacial Cycle (last 125,000 years), the period for which we can best define past ice sheet behaviour.

世界上最大的冰块对气候变化的反应很重要，因为融化导致海平面上升。通过更好地了解过去冰盖对大气二氧化碳变化的反应，我们预测气候变暖下冰量和海平面变化的能力将得到加强。现在已经有了改进的数值模型，可以对南极冰进行逼真的模拟。这些模型将进一步发展，并限制对现有的和新的现场证据的最后一个冰川周期（过去125,000年），这段时间，我们可以最好地定义过去的冰盖行为。
