COLLABORATIVE RESEARCH: Southern Andes Paleoclimate; A Testof Abrupt Ocean-Atmosphere Reorganizations in Glacial Cycle

全球气候突然重组的理由 系统依赖于冰川终止的速度和 冰期气候南北半球同步性和对称性 变化 本项目的主要目标是通过以下方式测试本案例： 建立了南半球中纬度地区的精确解剖结构 智利安第斯山脉的古气候。 如果突然重组 终止，完善的智利古气候记录应该 与北方半球相匹配，特别是北半球可能 没有显示出这种相关性。 这将是一个强有力的论据， 全球模式转换假设，也可以反映 南极海冰的影响。

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.
