WASHINGTON (AP) — Earth''s protective ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. For the first time in 35 years, scientists were able to confirm a statistically significant and sustained increase in stratospheric ozone, which shields the planet from solar radiation that causes skin cancer, crop damage and other problems. green living ozone layer

Discovery of the depletion of the ozone layer was a watershed moment in the ecological timeline of our world.

Its less than desirable effect on the Earth’s protective sheath, the ozone layer was well highlighted.

Four New Man-Made Gases Found That Harm Ozone Layer, Scientists Say

OSLO, March 9 (Reuters) - Scientists have detected four new man-made gases that damage the Earth''s protective ozone layer, despite bans on almost all production of similar gases under a 1987 treaty, a study showed on Sunday. The ozone layer shields the planet from damaging ultra-violet rays, which can cause skin cancer and eye cataracts, and has been recovering after a phase-out of damaging chemicals under the U.N.''s

The study further found that if action is not taken to reduce current emission rates, the vital atmospheric layer will shrink another 1 kilometer by 2080. The stratosphere is the second atmospheric layer after the troposphere. It is home to the ozone layer , which protects the Earth from harmful UV rays. Although experts have long known that the stratosphere was shrinking, it was initially thought that it was caused by the depletion of the ozone layer.

Nitrous Oxide New Leader In Ozone Depletion

Their study revolved around ozone-depleting compounds, particularly nitrous oxide. The ozone was once a highly debated global concern that created the Montreal Protocol. The Montreal Protocol, which came to be in 1987, limited ozone-depleting compounds. The researchers found that nitrous oxide is becoming the leading man-made reason for ozone loss. However, as these compounds decreased due to the agreement, nitrous oxide was increasingly harmful to the ozone.
