Graph: 11-Year Cyclic Antarctic Ozone Hole and Stratospheric Cooling (image) University of Waterloo Share Print E-Mail Caption Chlorofluorocarbons are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal of Modern Physics B this week. The graph demonstrates the near perfect correlation between observed temperature data and Professor Qing-Bin Lu's cosmic-ray-driven electron-reaction (CRE) theory of ozone depletion.
