If we keep up with our current practices of decreasing our use of ozone-depleting compounds, a report that has the support of the United Nations (UN) predicts that the ozone layer that surrounds our planet would be fully recovered by the year 2066.
Nearly one hundred substances, such as chlorofluorocarbons (CFCs), which are typically found in aerosols, were identified as being detrimental to the health of our planet's ozone layer in accordance with the Montreal Protocol, which was ratified universally in 1987. This protocol was designed to protect the ozone layer from harmful substances.
A report on the progress made toward regulating the use of these compounds has been released once every four years by the Scientific Assessment Panel to the Montreal Protocol on Ozone Depleting Substances. The protocol's goal was to regulate the use of these substances.
When it comes to the process of rebuilding the ozone layer, the most recent report, which will be delivered at the 103rd annual meeting of the American Meteorological Society, which is presently taking place, has shown that we are headed in the correct direction.
According to the statistics, it has been anticipated that it should be recovered by the year 2040 for the majority of the planet, over the Arctic region by the year 2045, and over the Antarctic region by the year 2066.
Additionally, the report mentioned the positive progress that has been made in terms of the reduction of hydrofluorocarbons (HFCs). HFCs are substances that have been used as alternatives to CFCs because they are considered to be less harmful to the ozone layer; however, they are still regarded as being harmful to the environment.

In spite of the fact that these HFCs do not directly compromise the stability of the ozone layer, they do contribute to the problem of global warming. The Montreal Protocol was accordingly amended to also target the reduction of these HFCs, which according to the report appear to have had progressively lower usages over the years.
If we keep moving in the same direction that we are going right now, projections show that we will be able to avoid an increase in temperature of approximately 0.3 to 0.5 degrees Celsius (0.54 to 0.9 degrees Fahrenheit) by the year 2100.
"It is very encouraging to see that the regeneration of the ozone layer is on track according to the most recent quadrennial study. It is impossible to overestimate the importance that the Montreal Protocol has played in the fight against climate change "Meg Seki, who serves as the Executive Secretary of the Ozone Secretariat for the United Nations Environment Program, made this statement.
"The Protocol has evolved into a genuine advocate for the environment over the course of the past 35 years."
Professor Petteri Taalas, who serves as the Secretary-General of the Globe Meteorological Organization, stated that these beneficial accomplishments should serve as encouragement for the rest of the world to continue working towards positive environmental consequences.
"The mitigation of ozone depletion serves as a model for addressing climate change. Our accomplishment in eliminating chemicals that deplete the ozone layer demonstrates what can and must be done — as a matter of urgency — to transition away from fossil fuels, reduce greenhouse gases, and consequently limit the increase in temperature "he added.
