Ozone Hole

[MGC]

Don't hear much about the ozone hole anymore. Has it gone away or has scientific study determined that it really isn't that significant? I checked the CPC Ozone Hole page and it has not been updated since Oce 2002. What gives? Just a few years ago we were all going to burn up due to UV light.......MGC

It's still there (or more realistically is there during the late Austral Winter into Spring). In recent years it hasn't been quite as large as before as the CFC ban seems to have worked. The Ozone Hole per se will always be there as long as Antarctica sits at the South Pole because it's a function of the intense surface cold and the lack EUV radiation from the Sun when it's below the horizon. It was not its seasonal presence that was the issue but the enlargement of it which suggested the overall Ozone levels aloft had decreased globally allowing the expansion of the Seasonal hole into latitudes where it had never reached before.
