Abstract. Based upon research results over the past five decades, there has been a general acceptance that the ice ages were initiated by astronomical phenomenon. Specifically, marine, ice and terrestrial paleoclimate data have supported elements of the Milankovitch astronomical theory of the ice ages. However, there remain unresolved problems between the empirical findings and theory. The 100 thousand year problem has been the subject of extensive research since a 100 thousand year cycle that matches the Earth orbit eccentricity period dominates the frequencies found in paleoclimate records. Yet, eccentricity produces an insignificant variation in annual solar energy. Other problems include the Stage 11 problem, the missing interglacials problem, how glaciation is sustained over multiple tens of thousands of years and synchronous hemispheric glaciation. I shall show these problems are resolved by modification of the prevailing Milankovitch theory. In particular, two elements of the theory need modification. One is the limitation of eccentricity's role and the other assuming that glaciation results only from cool summer conditions. By applying the Solar Energy Invariance law to define e-seasons, how eccentricity provides conditions for glaciation is demonstrated. The results show eccentricity variations provide significant solar energy variations at the top of the earth's atmosphere to produce glaciation that is global. Global glaciation results in colder winter glaciation occurring in one hemisphere simultaneous with cool summer glaciation in the other hemisphere. Analysis with these modifications resolves each of the problems.

修正的米兰科维奇理论,调和了与古气候记录的矛盾

摘要。根据过去五十年的研究结果,人们普遍认为冰河时代是由天文学现象引发的。具体而言,海洋,冰和陆地古气候数据支持了冰河时期米兰科维奇天文理论的要素。但是,经验发现和理论之间仍然存在未解决的问题。在10万年的问题进行了广泛的研究,因为一个10万年周期相匹配的地球轨道偏心率时期占主导地位的古气候记录中发现的频率的主题。但是,离心率在年度太阳能中产生的变化很小。其他问题包括第11阶段问题缺少中间层问题,冰川如何在数万年的历史中得以维持以及同步的半球冰川。我将说明,通过修改流行的Milankovitch理论可以解决这些问题。特别是该理论的两个要素需要修改。一种是偏心作用的局限性,另一种是假定冰川融化仅源于凉爽的夏季条件。通过应用太阳能不变性定律定义电子季节,可以证明偏心率如何为冰川化提供条件。结果表明,偏心率变化在地球大气层的顶部提供了显着的太阳能变化,从而产生了全球性的冰川作用。整体冰川作用导致一个半球冬季寒冷,而另一半球夏季凉爽。
