Although it sounds at first like a claim from astrology, there is sound scientific evidence that the motions of the planets have a profound influence on Earth’s climate. The basic theory was formulated by the mathematician Milutin Milankovitch almost a century ago, but was verified by scientific evidence only in 1976.
In this session, we explore both the theory and the evidence that subtle changes in Earth’s orbit caused by the motions of the other planets are linked to the ice ages of the past. We also explore the extent to which these natural cycles are being disrupted by human activity.
Talk presented by Professor Richard McGehee of the University of Minnesota as part of the Department of Mathmatics Tamura/Lilly Lecture Series.
The talk was excellent. It explained well a topic that is not so simple. Dr. McGhee, the speaker, was entertaining without simplifying too much the topic.
