Ozone hole may disappear because of reduction in chlorofluorocarbons |

Report: Ozone Hole May Disappear by 2050
By Associated Press
TOKYO --
The ozone hole over the Antarctic is likely to begin contracting in
the future and may disappear by 2050 because of a reduction in the
release of chlorofluorocarbons and other ozone-depleting gases,
according to a team of Japanese scientists.
The findings are based on a series of numerical simulations carried
out by Eiji Akiyoshi of the National Institute for Environmental
Studies, near Tokyo, using projected emissions of chlorofluorocarbons
and other gases blamed for the ozone hole.
According to a report posted Friday on the institute's Web site, the
hole is at its largest now but is likely to gradually start
contracting around 2020 and disappear by around 2050.
The team's findings are in line with research by other scientists.
Some, however, have suggested the hole won't heal until much later
because old refrigerators and air-conditioning systems -- many in the
United States and Canada -- are still releasing ozone-killing
chemicals.
Both countries curbed those chemicals in newer products.
Satellites and ground stations have been monitoring the ozone hole
over the South Pole since its discovery in the 1980s.
Chlorofluorocarbon levels in the earth's atmosphere have been
declining since the mid-1990s due to international efforts to reduce
emissions.

It will take much longer than that. The Earth can't heal itself properly
until all begin to do something to aid it.
