2008 ozone hole larger than 2007's hole
"This year the area of the thinned ozone layer over the South Pole reached about 27 million square kilometers, compared to 25 million square kilometers in 2007 and a record ozone hole extension of 29 million square kilometers in 2006, which is about the size of the North American continent," the ESA said.
Scientists said the depletion of ozone is caused by extremely cold temperatures at high altitude and the presence of ozone-destructing gases such as chlorine and bromine, originating from man-made products like chlorofluorocarbons, which were phased out under the 1987 Montreal Protocol but linger in the atmosphere.
Julian Meyer-Arnek of the German Aerospace Center which monitors the hole annually, said since the polar vortex remained undisturbed for a long period, the 2008 ozone hole has become one of the largest ever observed.
The annual analysis is based on data provided by instruments aboard the ESA's Envisat, ERS2 and MetOp satellites.

about the ozone layer
surely some shrinkage is good better than nothing is it not ice caps are melting but not at the magnitude it was at. I read somewhere the ice cap are not melting at such an alarming rate the were at clearly at. Does it not show the governments are starting to act on this which i s great news but governments do need to do more though and also show the way to third world countries to as well as to help the underfunded countries too its all helps to save our sacred planet from destruction for out future generations also man kind

Again with the Hole?
If it isn't "Global Warming" or a "New Ice Age" it is the "Ozone Hole". Since it has been found in the 50's, and scientists have been watching it, the hole has NATURAL fluctuations in size. It grows in the cooler months and shrinks in the warmer months. So what is the big deal? This is of the same caliber as the Global Warming thing everyone has their panties scrunched up about.
