Study shows CFCs, cosmic rays major culprits for global warming
"Cosmic rays and chlorofluorocarbons (CFCs), both already implicated in depleting the Earth's ozone layer, are also responsible for changes in the global climate, a University of Waterloo scientist reports in a new peer-reviewed paper."

And of course there is actually another connection this study does not take into account.
"Back in the 1950s, the Americans, the British, the French and the Russians tried to impress each other by "testing" atomic weapons. This involved blowing up multi-megaton bombs in the air in remote places, but the explosions didn't stay local."

Nuclear testing has had detrimental effects on the stratosphere.
"Changes in trace stratospheric gases can result for detonations in the atmosphere if the fireball rises into the stratosphere. In this case, the high temperatures of the fireball destroy ozone and create various oxides of nitrogen. For large numbers (hundreds or thousands) of high yield detonations, these changes can exceed natural variations. Such depletion of ozone would increase solar ultraviolet reaching the Earth's surface. Nitrogen oxides tend to produce a global cooling effect. Both consequences would return to normal over periods of years."

In conclusion, CFC's were possibly scapegoated, to cover up the fact that high altitude atomic tests had literally burned a whole in the stratosphere in the 1950's.
