Scientists have revealed that the hole in the ozone layer over Antarctica is likely to initiate with its happy ending, getting smaller - first spotted 25 years after it was discovered.

The news is attributed to the unprecedented international action taken over against the menace.

The ozone layer lies between about 9.3 and 18.6 miles (15 and 30 kilometers) above the Earth's surface. This dense ozone layer, or O3, prohibits most of the harmful sun's high-frequency ultraviolet rays to reach the earth's surface.

The hole, which appears each year, was first discovered by British scientist Jonathan Shanklin and two others in May 1985.

However, it was posted that it has been about the same size for the past 15 years, coming out with this outlandish news after that.

Jonathan Shanklin posts that he expects ozone depletion to start reducing each year, with ozone levels eventually returning to natural levels in 2080.

National Institute of Water and Atmospheric Research scientist Richard Mackenzie reveals that the recovery may have begun already.

In addition, however, the recovery pattern is cited to be unpredictable primarily due to constraints like complex interactions between ozone depletion and climate change factors.
