LONDON: You cannot see it with the naked eye but high over your head, just above the altitude at which the highest-flying passenger jets cruise, there is a fragile layer of naturally occurring gas that shields all life on Earth from the deadly effects of the ultraviolet radiation emitted by the sun. This is the ozone shield, a belt of gas — specifically ozone, or O3, which is

The ozone layer that shields life on Earth from deadly solar radiation is on track to recover within decades, but controversial geoengineering schemes to blunt global warming could reverse that progress, a major scientific assessment warned Monday.

Industrial aerosols have led to depletion of ozone in stratosphere since mid-1970s.
