研究揭示了过去变暖期的转变 南大洋的洋流, 释放更多的碳, 类似于今天的气候变化。 Study reveals past warming periods shifted Southern Ocean currents, releasing more carbon, akin to today’s climate changes.

来自卡迪夫大学的研究人员发现,过去的全球升温期改变了南大洋的洋流和风向,导致自然碳向大气的释放增加。 Researchers from Cardiff University found that past global warming periods shifted ocean currents and winds in the Southern Ocean, leading to increased natural carbon release into the atmosphere. 南极极地洋流(ACC)在这些变化中发挥了关键作用。 The Antarctic Circumpolar Current (ACC) played a key role in these shifts. 人类引起的气候变化今天正在造成类似的进程,突出表明需要采取紧迫的气候行动。 Human-induced climate change is causing similar processes today, highlighting the need for urgent climate action. 南大洋吸收了全球二氧化碳排放量的40%左右,因此对于全球控制热和碳吸收至关重要。 The Southern Ocean absorbs about 40% of global CO2 emissions, making it crucial for regulating heat and carbon uptake globally.
