Recovering Ozone Layer is Well on Its Way! What Does This Mean for Earth and When It Will Be Completely Healed?
A UN-backed panel of experts certifies the phase out of nearly 99% of prohibited ozone-depleting chemicals has helped.
There is a glimmer of hope coming from the surface of the globe despite mounting worries about climate-related calamities and extreme weather events around the world. According to scientific analysis, the ozone layer is on track to fully regenerate within the next four decades.
Chemically active forms of chlorine and bromine originating from human-produced substances are released during reactions on high-altitude polar clouds every September, causing the ozone layer above Antarctica to weaken.
United Nations-backed scientists say they’ve found evidence that eliminating ozone-depleting compounds has helped. The ozone hole is expected to be completely filled by 2066, according to the report published every four years by the Scientific Assessment Panel to the Montreal Protocol on Ozone Depleting Substances.
The United Nations Environment Program has issued a statement predicting that “if current policies remain in place, the ozone layer will recover to 1980 values (before the appearance of the ozone hole) by around 2066 over the Antarctic, by 2045 over the Arctic, and by 2040 for the rest of the world.”
The ozone hole continued to decrease in size during 2022, reaching a median size of 23.2 million square kilometers between September 7 and October 13, 2022.
It’s official: the Montreal Protocol has had a positive effect on the climate, as evidenced by this newest report. It is anticipated that if we reduce our use and production of hydrofluorocarbons by half by 2100, we can prevent global temperatures from rising by 0.3 to 0.5 degrees Celsius.
In addition, the evaluation shows that the Protocol has matured into a genuine champion for the environment over the past 35 years and that the way forward must be maintained to prevent global warming.
“It is impossible to overstate the importance of the Montreal Protocol in the fight against climate change. The Protocol has evolved over the past 35 years to become a leading environmental protection measure “According to a statement released by UN Environment Programme Ozone Secretariat Executive Secretary Meg Seki.
The discovery that the ozone layer would be entirely repaired in a few decades demonstrates that climate-related extreme weather events can be positively impacted by a global effort. In light of the recent announcement by the U.S. government to give an additional $100 million to help Pakistan rebuild after last year’s disastrous floods, this latest assessment seems timely.
Protecting the ozone layer paves the way for addressing climate change. “Our achievement in phasing out ozone-eating chemicals shows us what can and must be done – as a matter of urgency – to transition away from fossil fuels, cut greenhouse gases, and therefore limit temperature increase,” said WMO Secretary-General Prof. Petteri Taalas.
