For comparison, here is 1979-2007. NASA's been tracking the thinning of the ozone layer the south pole for nearly 20 years. In this slowed-down animation, you can watch the ozone hole's average size each October: http://www.youtube.com/watch?v=taTzqRHNIEc

And 2008: http://www.youtube.com/watch?v=Ujkvw5BF1Yc The Antarctic ozone hole reached its annual maximum on Sept. 12, 2008, stretching over 27 million kilometers, or 10.5 square miles. The area of the ozone hole is calculated as an average of the daily areas for Sept. 21-30 from observations from the Ozone Monitoring Instrument (OMI) on NASAs Aura satellite.

This is considered a moderately large ozone hole, according to NASA atmospheric scientist, Paul Newman. And while this years ozone hole is the fifth largest on record, the amount of ozone depleting substances have decreased about 3.8% from peak levels in 2000. The largest ozone hole ever recorded occurred in 2006, at a size of 10.6 million square miles.

1. For some reason, I was under the false impression that we had

fixed the ozone problem.

So, what happened in 2002, that made it practically disappear?
