一系列巨大的气候突变不时打断末次冰期。尽管关于这些变化的幅度、时间和区域范围的大量证据已经获得 ,但是在这些变化之后的物理过程仍然知之甚少。问题是没有人能提出一个令人满意的设想来满足以下 4个主要要求。第一 ,这个设想必须刻画气候系统跳跃状态的特点 ;第二 ,这个 A series of catastrophic climate breaks occasionally interrupted the last ice age. Although a great deal of evidence has been drawn about the magnitude, timing and extent of these changes, the physical processes following these changes are still poorly understood. The problem is that no one can come up with a satisfying idea to satisfy the following four main requirements. First, this vision must characterize the state of the climate system’s jump; second, this
