COSMIC rays are off the hook as a cause of the ozone hole, says Rolf Muller, an atmospheric scientist at the Research Centre in J眉lich, Germany.
It has been suggested that cosmic rays鈥� high energy eats away at the ozone hole by breaking down man-made chlorofluorocarbons. But Muller found no correlation between the activity of cosmic rays and ozone levels in the polar regions, where the CFC breakdown was supposed to take place.
