UN: Ozone Layer Recovery on Track by 2050

UN Confirms Ozone Layer to Recover by 2050
Antonio Guterres, the United Nations Secretary-General, announces that the ozone layer is on track for full recovery by 2050. This progress comes from global efforts to reduce ozone-depleting substances (ODS) through the Montreal Protocol and the Kigali Amendment.
Historical Context
The ozone layer protects humans and the environment from harmful ultraviolet radiation from the sun. In the 1970s, scientists identified that human-made chemicals like chlorofluorocarbons were depleting this vital layer.
International Agreements
Countries adopted the Montreal Protocol to address this issue, a global treaty aimed at phasing out ODS and regulating their production and consumption. This agreement has significantly reduced the use of harmful substances.
Current Climate Solutions
In his World Ozone Day message on September 16, Guterres emphasized the importance of climate solutions, including improvements in refrigerants and energy efficiency. These measures are crucial to preventing a climate crisis by mid-century.
The Kigali Amendment
The Kigali Amendment targets a reduction in hydrofluorocarbons (HFCs), potent climate-warming gases. If fully implemented, this amendment could prevent up to 0.5 degrees Celsius of global warming by the end of the century. While four out of five nations have ratified the amendment, Guterres stressed the urgency of timely action.
Global and National Progress
The UN Climate Change account on social media confirmed that the ozone layer is on track for full recovery by 2050, with global reductions in ODS reaching 98 percent. Additionally, Nigeria’s Minister of State for Environment, Iziaq Salako, announced that the country has moved to stage three of its plan to phase out ODS.
