中文摘要
全球气候系统的突然重组是基于冰川终止的速度和冰期气候变化的半球间同向性和对称性。该项目的主要目标是通过在智利安第斯山脉建立南半球中纬度古气候的精确解剖来测试这种情况。如果是一个突变的重组终止,那么完善的智利古气候记录应该与北半球相符,特别是北半球可能没有这种相关性。这将是反对全球模式转换假说的有力论据,也可能反映南极海冰的强迫作用。
英文摘要
The case for abrupt reorganizations of the global climate system rests on the rapidity of glacial terminations and the interhemispheric synchroneity and symmetry of ice-age climatic change. The primary goal of this project is to test this case by establishing a precise anatomy of Southern Hemisphere mid-latitude paleoclimate in the Chilean Andes. If an abrupt reorganization of termination, the perfected Chilean paleoclimatic record should match that of the Northern Hemisphere, particularly the North may show no such correlation. This would be a strong argument against the global mode-switch hypothesis and could alternatively reflect forcing by Antarctic sea ice.
