Over the antarctic is a loss of ozone. The Montreal Protical worked to solve the problem in 1987. It said we had to stop using ccf’s and Nasa did another study to affirm this decision. Their study showed the ozone layer would deplete by two thirds by 2065. Levels are not returning to normal. We are still looking into the problem, but it is better. We need to educate people about the problem. There is much more to the story. Recently, the winds in the antarctic seem to be a serious problem. We seem to have a connection between climate change and the Ozone Hole. The Montreal Protical may help or be a stepping stone to change our climate problems in the future. We can use this existing idea to help implement more in the future.:http://www.theozonehole.com/nasaarctic.htm
