与北极形成鲜明对比的是,自1979年以来,南极海冰总面积出现了统计上显著的积极趋势。然而,观测到的南极海冰范围短暂且高度可变,限制了充分了解这些最近变化的历史背景的能力。为了应对这一挑战,我们创建了自1905年以来季节性南极海冰范围的强大的,基于观测的重建集合。使用这些重建,在这里,我们表明,自1979年以来的观察期是唯一的时间,所有四个季节表现出显着增加南极海冰总量的背景下,在二十世纪,所观察到的增加是并列对统计上显着减少整个世纪早期和中期。这些重建提供了可靠的估计季节性解决南极海冰总的范围,并有足够的技巧,以更好地了解南极气候系统内的空气-海冰相互作用的方面。
In stark contrast to the Arctic, there have been statistically significant positive trends in total Antarctic sea ice extent since 1979. However, the short and highly variable nature of observed Antarctic sea ice extent limits the ability to fully understand the historical context of these recent changes. To meet this challenge, we have created robust, observation-based reconstruction ensembles of seasonal Antarctic sea ice extent since 1905. Using these reconstructions, here we show that the observed period since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century and that the observed increases are juxtaposed against statistically significant decreases throughout much of the early and middle twentieth century. These reconstructions provide reliable estimates of seasonally resolved total Antarctic sea ice extent and are skilful enough to better understand aspects of air–sea–ice interactions within the Antarctic climate system.
