The World Meteorological Organization Bulletin, WMO, reported that the low level of ozone depletion observed in 2024 was partly due to naturally occurring atmospheric factors, which drive year-to-year fluctuations. However, the long-term positive trend reflects the success of concerted international action.
This year, we celebrate 35 years of the Vienna Convention and 35 years of global ozone layer protection. Life on Earth would not be possible without sunlight. But the energy emanating from the sun would be too much for life on Earth to thrive were it not for the ozone layer. This stratospheric layer shields Earth from most of the sun’s harmful ultraviolet radiation. Sunlight makes life possible, but the ozone layer makes life as we know it possible.
