Squeezing the Juice out of Paleoclimate Proxies

Broecker, Wallace S.哥伦比亚大学，lamant - doherty地球观测标题：从古气候代用物中挤出“Juice”这个“基于完成的更新”支持了过去15万年的古气候记录及其对我们温室未来的影响。这项工作的重点是研究格陵兰冰芯记录中突出显示的气候突变的原因，并破译这些过去的变化中有多少是突然发生的，而有多少是轨道强迫的简单正弦响应。大而突然的全球气候变化可能反映了大气水汽库存的不连续跳跃，因此被逐出热带。W.S. Broecker博士试图重建低纬度地区过去水文循环的变化，并继续探索海洋的温盐环流。

Abstract ATM-9730546 Broecker, Wallace S. Columbia University, Lamont-Doherty Earth Observatory Title: Squeezing the Juice Out of Paleoclimate Proxies This "Accomplished-Based Renewal" supports work on the paleoclimate record for the last 150,000 years and its implication to our greenhouse future. The work is focussed on the causes of the abrupt climate changes which are so prominently displayed in the Greenland ice core records and to decipher how much of these past changes have come in abrupt steps as opposed to how much has been a simple sinusoidal response to orbital forcing. The large and abrupt global climate shifts may reflect discontinuous jumps in the inventory of atmospheric water vapor and are hence driven from the tropics. Dr. W.S. Broecker seek ways to reconstruct past changes in the hydrologic cycle at low latitudes and continue to explore the ocean's thermohaline circulation.
