CFC Destruction of Ozone - Major Cause of Recent Global Warming! Sep 5, 2009
CFCs destroyed ozone in the lower stratosphere-upper troposphere causing these zones in the atmosphere to cool 1 ... The loss of ozone allowed more UV light to pass through the stratosphere at a sufficient rate to warm the lower troposphere plus 10" of the earth by 0.48 oC (1966 to 1998).

How Sunlight Can Control Climate Sep 1, 2009
But this change also begins to affect the circulation of the stratosphere itself, which then alters the circulation in the lowest layer of the atmosphere, known as the troposphere, by reinforcing certain wind patterns that then affect the weather we experience. Meanwhile, the increased radiance during the also adds slightly more heat to the ocean in areas that are already relatively cloudless because of sinking, cooler air. (Scientific American)
