The protective ozone layer that started depleting heavily in the 1980s is on a recovery mode, according to a new assessment by 300 scientists across the world. ‘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.
But the news for India is grim. Tropical countries were not significantly affected by the above ozone depletion problem. But, along with severe climate change impacts, India and other tropical regions may face an ozone depletion problem towards the end of the century. Gufran Beig, project director at System of Air Quality Weather Forecasting and Research (SAFAR) of IITM, Pune and the only Indian scientist in the international expert review team has flagged off certain ozone concerns for India. Climate change is inducing a change in circulation patterns in the upper layers of the atmosphere that will influence ozone concentration adversely, he has said in his submission.
