A new expanded edition of the groundbreaking investigation into early high cultures and ancient solar outbursts "Schoch proposes, based on findings from several different scientific fields, that back around 9700 BCE what he described as an agitated Sun brought the last ice age to a sudden end. He believes that solar outbursts brought about powerful electrical/plasma discharges upon our planet, resulting in severe climate change that involved increased earthquakes, volcanic activity, massive floods, and high radiation levels.Schoch writes how this brought about a Solar-Induced Dark Age (SIDA) that set humanity back thousands of years, and he warns that such a solar outburst could happen again and could have a devastating impact upon our modern civilization. He reveals evidence that our sun is far more unstable than we previously realized."
