Antarctic ozone hole. Satellite image of the ozone hole (purple) over Antarctica (centre) on 29th September 2000. Ozone layer thicknesses are colour coded from purple (lowest) through blue,cyan and green to yellow (highest). This was the broadest ever hole,stretching over 29.9 million square kilometres. Chlorofluorocarbons (CFCs),which were responsible for much of the ozone depletion were phased out from the late 1980s to the mid 1990s,but the damage to the ozone didn't peak until 2006.
