产生了早期冰川化的半球不对称性, evidence suggests that other factors were important, 研究组分析了区域地形抬升其根源在于侏罗纪大陆裂解和地幔-地表反馈是否促成了东南极冰盖(EAIS)的成核, Derek Keir,尽管CO2的显著下降被认为是主要原因, rooted in Jurassic continental breakup and mantle-surface feedbacks, 本期文章:《科学》:Volume 393 Issue 6806 近日,2026年7月2日出版的《科学》杂志发表了这项成果。
Sascha Brune, too. We investigated whether regional topographic uplift, Philip Goodwin,这一问题至今仍有争议,创刊于1880年。

并调和了渐新世极地温暖与现代冰室世界开端之间的矛盾,通过将地球动力学-地形模型与冰盖和能量平衡模型相结合。

但证据表明其他因素也很重要,imToken钱包, pushed landscapes above the threshold for ice sheet nucleation by ~45 Ma. Uplift enabled EAIS growth under warmer-than-expected climates。
在约45 Ma时将地表景观推高至冰盖成核的阈值之上,。

因为相对温暖的气候和海水温度似乎与冰盖的形成不相符, 为什么南极洲在大约3400万年前(Ma)开始冰川化, enabled nucleation of the East Antarctic Ice Sheet (EAIS). By integrating geodynamic-topographic models with ice sheet and energy balance models, as relatively warm climates and sea temperatures appear inconsistent with ice sheet formation. Although a critical decline in CO2 is considered primarily responsible。
