Unlike Le Quéré et al. (Reports, 22 June 2007, p. 1735), we do not find a saturating Southern Ocean carbon sink due to recent climate change. In our ocean model, observed wind forcing causes reduced carbon uptake, but heat and freshwater flux forcing cause increased uptake. Our inversions of atmospheric carbon dioxide show that the Southern Ocean sink trend is dependent on network choice.
与勒奎尔等人（《报告》，2007年6月22日，第1735页）不同，我们未发现近期气候变化导致南大洋碳汇饱和。在我们的海洋模型中，观测到的风应力导致碳吸收减少，但热量和淡水通量应力导致碳吸收增加。我们对大气二氧化碳的反演结果表明，南大洋碳汇趋势取决于网络选择。
