A computer model of coupled ice sheet-ice shelf behavior was used to evaluate whether observed changes in atmospheric CO(2) concentration could have caused the advance and retreat of Pleistocene ice sheets in the Eurasian Arctic. For CO(2) concentrations below a threshold of approximately 250 parts per million, an extensive marine-based ice sheet covering Scandinavia, the Barents, Kara, and East Siberian seas, and parts of the Arctic Ocean developed in the model simulations. In the simulations, climatic warming associated with the Holocene rise of atmospheric CO(2) was sufficient to collapse this widespread glaciation and restore present-day ice conditions.
利用冰盖-冰架耦合行为的计算机模型来评估观测到的大气二氧化碳浓度变化是否可能导致了欧亚北极地区更新世冰盖的进退。对于低于约百万分之250这一阈值的二氧化碳浓度，在模型模拟中形成了一个覆盖斯堪的纳维亚半岛、巴伦支海、喀拉海、东西伯利亚海以及北冰洋部分区域的广泛的海洋型冰盖。在模拟中，与全新世大气二氧化碳上升相关的气候变暖足以使这种广泛的冰川作用崩塌，并恢复到现今的冰况。
