New insights on the forcing of Quaternary ice-age terminations

这个项目调查了地球气候最后一次经历重大变化的时期。使用新颖的技术，它结合了来自洞穴沉积物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。这一结果将为解释这些周期的假设提供第一个强有力的检验，从而完善冰期的天文学理论。它们还将提供北半球冰盖历史的基本参考记录，这将补充即将到来的南极冰芯的数据。总之，这将更好地理解当前和预计的温室变暖。

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.
