Note from Dr. Easterbrook:
“I just competed a study of all warm and cold periods over the post 800,000 years and stumbled upon what must be the cause of the Ice Age 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 in the past 800,000 years.
The data is truly remarkable˗˗every cool period 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 with full documentation is now available on Amazon. The age old riddle of the cause of Ice Ages is finally resolved!”
