The Neogene–Quaternary (Pliocene-Pleistocene) transition around 2.8 to 2.45 million years ago represents a fundamental shift in Earth’s climate system. The extreme glacial-interglacial oscillations that characterize our more recent climate emerged at this time, although the causes remain uncertain. Deep-ocean sediments offer clues to climate history owing to their continuous and well-dated character, and because the oceans themselves are crucial heat and CO

大约280万至245万年前的更新世-第四纪（上新世-更新世）过渡代表了地球气候系统的根本转变。作为我们近代气候特征的极端冰川-间冰期振荡就出现在这个时期，尽管其原因仍然不确定。深海沉积物提供了气候历史的线索，因为它们具有连续性和年代确定性，而且海洋本身是至关重要的热量和二氧化碳来源。
