Ozone loss disaster was avoided.

The above headline was printed on Friday, March 20, 2009 on page 3A of the St. Petersburg Times Newspaper from an Associated Press article: NASA credits the international cutback of CFC emissions. A NASA study about ozone-munching chemicals from aerosol sprays and refrigeration used a computer model to play a game of what-if. What if the world 22 years ago hadn't agreed to cut back on chlorofluorocarbons, which cause a seasonal ozone hole to form near the South Pole? NASA atmospheric scientest Paul Newman said the answer is a "bizarre world." By 2065, two-thirds of the protective ozone layer would have vanished and "the ozone hole covers the Earth." And CFC's, which are longlived potent greenhouse gases, would have pushed the world's temperature up 4 degrees.
Notice that nothing was mentioned that the current ozone hole is now listed at 16.5 million square miles versus what the reading was 22 years ago, 7.2 million square miles. That is an increase of 9.3 million square miles. NASA wants to blame the chemicals from areosol sprays and refrigeration as the culprits for depleating the ozone layer, when it is NASA and the other 45 Space Agencies that are depleating the ozone layer with their frequent launchings that are averaging a launch every 2.7 days.
