The project aims to analyse the trends in sea ice extent over the polar regions, and explain them in terms of changes in the local and remote atmospheric circulation. In recent decades, Arctic sea ice has decreased dramatically, while increasing in the Antarctic. The resolution of this paradox is a pressing issue in climate science, as is the broad question of how sea ice influences, and is influenced by, climate conditions in the mid-latitudes and tropics. Anticipated outcomes include a better understanding of the nature of links between Australian climate and Antarctic ice, and between United States climate extremes and Arctic ice.

该项目旨在分析极地地区海冰范围的趋势，并根据当地和远程大气环流的变化来解释这些趋势。近几十年来，北极海冰急剧减少，而南极海冰却在增加。解决这一矛盾是气候科学中的一个紧迫问题，正如海冰如何影响中纬度和热带地区的气候条件以及受其影响这一广泛问题一样。预期的结果包括更好地了解澳大利亚气候与南极冰之间以及美国极端气候与北极冰之间联系的本质。
