Correlation of megafauna extinctions and mega-biosphere disturbances with past supernova explosions has been accomplished by considering a time correction for supernova debris traveling at 88.2325 percent of light speed. Supernova W44 is responsible for the Piora Oscillation which appears to be the biblical event of Noah's Flood. The closest supernova explosion, Vela Jr at 652 light-years, gives the beginning of the greatest historical human disaster, The Black Death. When supernova debris energy input occurs in the northern or southern hemisphere, it causes heating (global warming) in the northern or southern hemisphere, respectively. Long term cooling, the Little Ice Age, occurs in the northern hemisphere when the incoming debris of exploding stars impacts only the southern hemisphere for hundreds of years. Termination of the last ice age results due to melting of numerous supernova impacts that correlate time of impact by changing sea level and geothermal energy released for 2,800 years from the exit crater of Dr. J. Kennet's nano-diamond meteor theory and part of the process involves Dr. O'Keefe's tektite theory. Correlation of Dr Frezzotti's ice melt Antarctica data with supernova impact times over the past 800 years establishes the Global Warming model in conjunction with the November 2016 Antarctic sea ice melt. 展开更多
