Earth Viz | Global Ozone 2002-2005
Ozone gas (O3) in the upper atmosphere shields Earth from the Sun’s dangerous ultraviolet radiation. Since the early 1980s, scientists have been aware that manmade chlorofluorocarbons (CFCs) destroy atmospheric ozone worldwide. The greatest losses have occurred at the poles; the Antarctic ozone "hole" is most extreme in October.
