冰崖崩塌的几率很低

南极洲对海平面上升的影响非常不确定。不确定性的一个重要来源是，人们对南极冰块消亡过程中的作用机制缺乏共识。在他们的研究中，来自达特茅斯学院的 Mathieu Morlighem 及其来自美国和英国的同事在三个冰盖模型中使用了新的海洋冰崖不稳定性（MICI）参数，以评估阿蒙森海海湾假定冰架消失后的海洋冰崖不稳定性风险。他们发现，即使冰崖前面目前具有稳定作用的冰架被移走，冰崖也不会坍塌。同样，在作者进行的模拟中，由于冰流增加和冰层变薄稳定了增加的冰排量，因此在接地线后退并暴露出更高的冰崖时，也不会出现坍塌。这些研究结果表明，虽然在全球变暖的情况下，南极洲西部仍有迅速融化的高风险，但在不久的将来，它可能不会受到 MICI 的影响。
