Development of the Ozone Hole over Antarctica

Plot of the area of the Antarctic ozone Hole, minimum ozone, and temperature anomaly from 1960 to 2012.

The area of the Antarctic ozone hole grew rapidly from the 1970s to the 1990s while minimum ozone in the hole decreased (NASA Ozone Hole Watch). Mean annual temperature anomaly in the Northern Hemisphere (red line) is smoothed with a centred 5 point running mean (HadCRUT3nh, 2013).
