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.
