Ozone hole 2006

19 years ago the nations of the world agreed to stop using freons, however the ozone hole in 2006 is larger than ever. During September the southern hemisphere/Antarctic ozone hole covered 28 million square kilometers. According to NASA the first measurable improvement will not occur until 2025, and the hole will not disappear until 2070. The graph is based on data from NASA's Total Ozone Mapping Spectrometer.
