NEW DELHI: The protective ozone layer that started depleting heavily in the 1980's is on a recovery mode according to a new assessment by 300 scientists across the world released on Thursday. "Assessment for Decision-Makers"-- a summary document of the Scientific Assessment of Ozone Depletion 2014 published by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) indicates that the ozone layer is expected to recover to 1980 levels before the middle of this century in many parts.
