No, there is not. ************ Carnivalius wrote in his extended answer, "This large build up of chemicals means that when the sunlight does reach the pole there is sudden pronounced drop in ozone and hence a complete lack of ozone if its severe enough." Sorry, but this is not born out by the data. Ozone levels over the poles decreases during the six months of the year when there is no sunlight to create new ozone and the levels increase when the sunlight returns (http://mywebpage.netscape.com/gwblaylock/Ozone.mov; note, you will need to install Apple's QuickTime software (http://www.apple.com/quicktime/player/)to view this movie. Also note that, between June and September of 2001, NASA changed the color scheme on the scale. This is just a cosmetic change. The values represented did not change.)

Holes in the ozone layer have been discovered in the recent past.

There is no hole in the atmosphere. There is however gaps in the ozone coverage of the earth. This is due to the naturally thin layer put there (something like a few mm is all that's required but don't quote me on that) when the atmosphere formed has been stretched so thin (by chemicals like CFC's that like to remove it) that gaps form. This is some concern for worry as Ozone provides a good deal of protection from harmful solar rays, hence why CFC's are banned in many countries etc.

This is a more indepth answer to your question and also an answer to a comment on my earlier one. There isn't infact a hole in the atmosphere itself, just a lack of ozone in certain areas over parts of the year. I should probably also state that CFC's themselves don't break down ozone but the CFC's own break down products do (when their hit by UV radiation for example they break down just as ozone does). 1) There has been a detected area of atmosphere where there was no ozone at all in a layer several km thick. The thing to understand is that ozone exists at all levels. It's production decreases as you move upwards and it's split faster the higher you go. This is due to various reactions that occur (called Chapman Reactions). The layer of ozone that forms from these reactions is called the "Chapman Layer". This hole is not permanent as the ozone depletion varies over the year. 2) There is evidence of ozone depletion in the heavily populated Northern Latitudes. There is a thinning in the North Pole (quite heavy I believe but not nearly as pronounced as that of the antarctic). The reason it is in the south is due to the unique weather conditions that form over its winter. When it is winter the weather pattern there creates a vortex of sorts that isolates it from the rest of the weather system. This coupled with the cold temperatures of below -80 degrees you get polar statospheric clouds forming. These differ greatly from normal clouds in that they are ice coupled with nitric acid. What these conditions do is to break down the chemicals into much more active forms (when they are hit by sunlight) than they could normally form. This large build up of chemicals means that when the sunlight does reach the pole there is sudden pronounced drop in ozone and hence a complete lack of ozone if its severe enough. To answer why this happens in the south is due to the land masses around the artic that help reduce the polar vortex that forms over its winter.
