Catalyst: The Hole Truth: Have we fixed the hole in the ozone

On the left is the world we're living with. On the right is the world where CFCs weren't banned. Low ozone concentrations are in blue, average is green. If you let chlorofluorocarbons increase by three per cent each year starting in 1974, by the year 2065, virtually twothirds of the ozone layer has been destroyed.

Ozone recovery shock: Nasa says hole in Ozone Layer should be

THE INFAMOUS hole in the ozone layer discovered around 40 years ago is repairing and should have half closed within five years, Nasa has sensationally claimed. Depletion of the ozone layer, which blocks out harmful UV radiation rays from the sun, was one of the great environmental scandals of the 1970s, when the hole first came to light, and more so 1980s when it was flagged as an international crisis, and led to bans on the use of chlorofluorocarbons (CFCs) in aerosols and fridges.

Looking forward, the Antarctic ozone hole should continue to recover gradually as CFCs leave the atmosphere, but complete recovery will take decades. CFCs have lifetimes from 50 to 100 years, so they linger in the atmosphere for a very long time, said Anne Douglass, a fellow atmospheric scientist at Goddard and the studys coauthor.
