Canada scientists claim presence of massive ozone hole over tropics; how it can impact your health
The amount of UV radiation that reaches the earth's surface would increase as the ozone layer depletes.
Researchers from Canada assert that they have found a sizable, year-round ozone hole in the lower stratosphere over the tropics.
Although it is seven times bigger, the hole is comparable in depth to the April hole in Antarctica.
Scientist Qing-Bin Lu from the University of Waterloo in Ontario, Canada, produced the discovery. Half of the surface of the globe is covered by the tropics
which also includes India and is home to most of the world's people. The new ozone layer may have a negative effect on life expectancy.
The discovery, which was not made using the traditional approach, has startled his contemporaries in the scientific world
He made use of the CRE model (cosmic ray-driven electron reaction). At the hole's centre, ozone levels have been found to be decreased by 80%, according to the study.
The sun's dangerous UV rays are absorbed by the ozone layer. Scientists asserted that industrial chemicals, such as chlorofluorocarbons, had begun thinning the ozone layer in the middle of the 1970s
Another group of researchers found the Antarctic Ozone hole in 1985. Although the ozone layer's levels improved after the compounds were outlawed in most nations, the hole still exists.
The ozone holes, according to the experts, are a significant factor in controlling stratospheric temperature.
The discovery will aid scientists in their understanding of the difficulty posed by climate change.
