The unusual ozone layer was found at an altitude of around 21 to 23 kilometres above the North Bay of Bengal and remained in place for more than a day. Researchers said the concentration was significantly higher than normally observed over eastern India. T...

The world's ozone layer is on "the road to long-term recovery" despite a destructive volcanic eruption in the South Pacific, the World Meteorological Organization said on Tuesday, after efforts to phase out ozone-depleting chemicals. On current trends, the ozone layer is on track to recover to 1980 levels by around 2066 over the Antarctic, 2045 over the Arctic and 2040 for the rest of the world, the United Nations agency said. Though the volcanic eruption near Tonga in early 2022 led to a shor...
