It's a combination boost of changes in ocean circulation, land ice dynamic and land subsidence caused by human activity.

这是人类活动引起的海洋环流、陆冰动力和地面沉降变化的综合结果。

The computer model was " able to measure a sudden weakening of the ocean circulation, " the team said in a statement.

该团队在一份声明中表示，该计算机模型“能够测量海洋环流的突然减弱”。

This is one of the major driving forces of Earth's deep ocean circulation: colder waters sinking and warmer waters rising up.

这是地球深海环流的主要驱动力之一：较冷的海水下沉，较暖的海水上升。

The Atlantic ocean circulation is slowing.

大西洋环流正在放缓。

The poverty of human understanding of ocean circulation, compared with that of the atmosphere, is therefore lamentable.

因此，与大气环流相比，人类对海洋环流的了解之贫乏令人遗憾。

Climate scientists are pretty confident that if human emissions of greenhouse gases follow worst case scenarios, we'd melt enough ice to see some slow down in this ocean circulation.

气候科学家笃信，如果人类排放温室气体按照最坏的情况发展，我们会融化足够多的冰，看到海洋环流放缓的那一天。

It's not 100% clear why this happened, but it might relate to changes in ocean circulation that took place when North and South America finally came together, and water could no longer circulate between the Pacific and the Atlantic.

为什么会这样发生还不是百分之百清楚，但这可能与北美和南美最终结合，太平洋和大西洋之间的水流不再循环发生的海洋环流变化有关。
