Climatic changes, magnetic intensity variations, and fluctuations of the eccentricity of the Earth's orbit during the past 2,000,000 yr and a mechanism which may be responsible for the relationship

The investigation of deep-sea climatic and magnetic records showing that high eccentricity of the Earth's orbit, low magnetic field intensity, and warm climate occur together indicates the relative importance of eccentricity as perhaps the phenomenon that has most consistently modulated both climate and magnetism for at least the past 2,000,000 yr. A speculative hypothesis regarding the mechanism that may be responsible for a relationship of the eccentricity of the Earth's orbit, geomagnetism, and climate is suggested.
