Antarctic Ozone Hole Is a Record Breaker

This from NASA... From September 21 to 30, the average area of the ozone hole was the
largest ever observed, at 10.6 million square miles. Scientists from NOAA's Earth System Research Laboratory in Boulder, Colo., use balloon-borne instruments to measure ozone directly over the South Pole. By Oct. 9, the total column ozone had plunged to 93 DU from approximately 300 DU in mid-July. For more on this see http://www.nasa.gov/vision/earth/lookingatearth/ozone_record.html
