The recovery of the depleted ozone layer may take 5-15 years more than that estimated earlier, says a recent study. It found that the regeneration of the protective layer will be pushed back from 2044 to 2049 over the mid-latitudes (30 0 -60 0 North and South) and from 2050 to 2065 over Antarctica.
The World Meteorological Organization, a UN agency, and the United Nations Environment Programme conducted the study with the help of 250 scientists from all over the world. The same group had conducted the earlier assessment in 2002.
