I just competed a study of all warm and cold periods over the past 800,000 years and discovered what must be the cause of the Ice Ages and other climate changes. I looked at oxygen isotope temperatures, deuterium temperatures, CET temperatures, sunspot numbers, total solar irradiance, production rates of beryllium-10 and radiocarbon, and cosmic ray intensity for every warm and cold period (for which data is available) in the past 800,000 years. The data is truly remarkable˗˗every cool period without exception was characterized by low sunspot numbers, indicating low strength of the sun’s magnetic field, and high production rates of beryllium˗10 and radiocarbon, indicating high intensity of cosmic rays. Every warm period was coincident with high sunspot numbers and low production rates of beryllium˗10 and radiocarbon. Thus, it is unequivocally clear that climate changes, large and small, are driven by fluctuations of the sun’s magnetic field. A book, “The solar magnetic cause of climate changes and origin of the ice ages” with full documentation is available on Amazon.
