According to a new report by the United Nations-backed panel of scientists, the ozone layer is on track to recover within four decades as ozone-depleting substances (ODSs) are gradually phased out globally.

Over the past few decades, scientists have discovered that the ozone layer is being depleted by human activities, particularly the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances. A thinning of the ozone layer, reported particularly over the poles and referred to as the “ozone hole,” has become humanity’s most feared environmental peril.

Recently, the UN, US, and EU compiled a scientific assessment of the ozone layer that confirmed the 1989 Montreal Protocol, an international agreement that eliminated most ozone-depleting chemicals, has been successful in restoring the ozone layer.

As of 2000, the Antarctic ozone hole was no longer expanding. And as long as current policies prevail, the ozone layer should recover over Antarctica around 2066, over the Arctic around 2045, and the rest of the world around two decades from now.

The panel also looked at the prospect of solar geoengineering by spraying aerosols into the stratosphere – known as a stratospheric aerosol injection (SAI) – to reflect sunlight out of the earth’s atmosphere. The controversial practice has the potential to reduce global temperatures. However, it is still under further research due to its potential consequences, such as deepening the Antarctic ozone hole and delay in ozone recovery.

While there have been some positive developments in recent years, the ozone layer is still not fully recovered and continues to face challenges.

Hence, hurry and answer the survey on earth’s ozone layer healing, according to a UN report on the Real Research app from January 16, 2023. After that, you will receive 70 TNCs as a reward.
