Nonsense! Ozone is created in the atmosphere thru a chemical reaction that requires sunlight. During the Antartic winter, there's little sunlight, therefore the ozone hole expands. During the Antartic summer, the ozone builds up and the "hole" is reduced.

Kermit, that's a dead on the money ... BINGO!

The Ozone Hole won't mend itself, because it isn't broken. It's been there ever since the Earth tilted 23 degrees on its axis.

Ever notice how all of these geniuses haven't figured out that with the sun shining lower on the horizon in the polar regions, the overhead ozone isn't as important anyway?

So, where's our Nobel Prize?

The graph [above] shows the measured total ozone above the Halley Bay station in Antarctica. Each point represents the average total ozone for the month of October. Note the sudden change in the curve after about 1975. By 1994, the total ozone in October was less than half its value during the 1970s, 20 years previous. This dramatic fall in ozone was caused by the use of man-made chemicals known as 'halogens' which include the well-known CFCs commonly used in fridges and so on. These CFCs had made their way into the upper atmosphere where the much stronger UV radiation from the Sun had broken them down into their component molecules, releasing the potentially damaging chlorine (and bromine) atoms, which, given the right conditions, could destroy ozone.
