在 2 0世纪 70年代初期出现了一种假说 ,按照这个假说 ,新生代中期改变气候的南极洲冰期是由于环南极洲海流诞生之后大陆的热隔离所造成的。从那时起由于日益增长的气候研究的迫切性 ,这个设想一直受地质学家的关注。现在已清楚 ,这个环绕冰大陆的海流产生于新生代早期 ,即澳大
A hypothesis emerged in the early 1970s according to which the mid-Cenozoic climate change in Antarctica was caused by the mainland’s thermal isolation after the birth of the Antarctic Ocean currents. Since then, this vision has been the focus of geologists due to the urgency of increasing climate research. Now it is clear that the current around the ice continent originated in the early Cenozoic, that is, Australia
