New insights on the forcing of Quaternary ice-age terminations

这个项目调查了地球气候上一次经历重大阶跃变化的时期。使用新的技术，它结合了来自洞穴沉积和海洋沉积物的特殊档案的信息，以精确地确定冰期周期的时间。这些结果将为解释这些周期而提出的假设提供第一个可靠的检验，从而完善冰河时代的天文理论。它们还将提供北半球冰盖历史的重要参考记录，这将补充即将到来的南极冰芯的数据。总而言之，这将更好地将当前和预计的温室气体变暖联系起来。

This project investigates the period when Earth's climate last experienced a major step change. Using novel techniques, it combines information from an exceptional archive of cave deposits and ocean sediments to precisely determine the timing of ice-age cycles. The results will provide the first robust test of hypotheses proposed to explain these cycles, leading to refinements in the astronomical theory of the ice ages. They will also provide an essential reference record of Northern Hemisphere ice-sheet history, which will complement data from forthcoming Antarctic ice cores. Together, this will better contextualise current and projected greenhouse warming.
