冰期剧烈的气候变化与大西洋环流的变化有关。在过去 1 0ｋａ间 ,气候较为稳定 ,百年级波动相对温和。目前 ,全球年复一年的气候变化主要由太平洋厄尔尼诺—南方涛动所引起。太平洋的赤道宽度是大西洋的 3倍 ,但不致于影响全球气候 ;大西洋的影响范围虽小 ,然而却非常明显 ,尤 The glacial climate change is related to changes in the Atlantic circulation. In the past 10 ka, the climate is more stable with relatively modest fluctuations. At present, the global year after year climate change is mainly caused by the Pacific El Niño-Southern Oscillation. The equatorial width of the Pacific Ocean is three times that of the Atlantic Ocean, but it will not affect the global climate; the impact range of the Atlantic Ocean is small, but very obvious, especially
