Assessing the vulnerability of East Antarctica to future warming

该DECRA旨在解决我们对南极冰盖如何应对气候变化的理解中的主要差距，通过对其对过去气候变暖的敏感性进行批判性见解。该项目将采用一套地球化学方法，以确定东南极洲最脆弱的盆地在过去变暖期间冰盖损失的程度，以及冰川融水对生物生产力和南大洋环流的影响。关于冰盖和海洋如何应对气候变暖的新知识将导致对未来海平面上升和气候的更可靠预测。该计划将为澳大利亚提供强有力的证据基础，为管理海平面上升影响的政策决策提供支持。

This DECRA aims to address major gaps in our understanding of how the Antarctic Ice Sheet will respond to climate change, by enabling critical insights on its sensitivity to past climate warming. The project will apply a suite of geochemical approaches to determine – for East Antarctica’s most vulnerable basin – the extent of ice-sheet loss during past warming, and the impact of glacial meltwater on biological productivity and Southern Ocean circulation. New knowledge of how the ice sheet and ocean respond to climate warming, will lead to more reliable projections of future sea-level rise and climate. The DECRA will benefit Australia by providing a strong evidence base for policy decision-making to manage the impact of sea-level rise.
