描述
Essef - The book is about the onset of the next ice age. Whether there will be another glacial period is not in question. As long as the Milankovitch cycles prevail, as long as the Sun's output is stable, and as long as there is significant land mass at high Northern Latitude there will be glacial epochs of approx. 100,000 years punctuated by interglacials of approx 12,000 years.
