Human activities are having an increasingly alarming impact on the environment and we must improve our predictive capabilities to decide on optimal societal responses. Foremost among these concerns are the current rise in anthropogenic CO2 and its effect on climate. Atmospheric CO2 and climate have also changed in the past as a result of natural cycles and the oceans have played a major role in these past variations. Exchange between the atmosphere and the ocean is one of the main factors regulating the level of atmospheric CO2 on a range of time scales and ocean circulation is an important contributor to the redistribution of solar heat on the surface of the planet. Today, the ocean is the major sink for anthropogenic CO2 and concerns have been raised that impending changes in deep water circulation could affect the future evolution of climate.

人类活动对环境产生越来越令人震惊的影响，我们必须提高我们的预测能力，以决定最佳的社会反应。这些关注点最重要的是人类二氧化碳的当前增加及其对气候的影响。大气二氧化碳和气候在过去的自然周期中也发生了变化，海洋在过去的这种变化中起着重要作用。大气与海洋之间的交换是调节大气二氧化碳水平在一系列时间尺度和海洋循环中的主要因素之一，这是使地球表面太阳热量重新分布的重要贡献者。如今，海洋已成为人为二氧化碳的主要水槽，并且人们担心深水循环的变化可能会影响气候的未来进化。
