A new MIT study confirms that the ozone hole over Antarctica is healing, thanks to global efforts to reduce ozone-depleting substances, with full recovery possible in the next decade.
After years of uncertainty and promise, it’s now confirmed: the ozone hole over Antarctica is recovering, thanks to global efforts to reduce ozone-depleting substances. A new study led by scientists at MIT shows, with high statistical certainty, that the ozone layer is healing as a direct result of efforts to reduce these harmful substances, not due to natural weather variability.
While there has been mounting evidence pointing to this recovery, this is the first study to quantify and confirm it with 95% confidence. Susan Solomon, a study author and prominent atmospheric chemist at MIT, expressed her optimism: "This is the first study that has quantified confidence in the recovery of the ozone hole... and it shows that we can solve environmental problems."
The ozone layer, located 15 to 30 kilometers above Earth’s surface, acts as a protective shield against harmful ultraviolet rays from the sun. In the 1970s and '80s, scientists discovered a significant hole forming over Antarctica, primarily caused by chlorofluorocarbons (CFCs). These compounds, used in aerosols, solvents, and refrigerants, released chlorine atoms in the stratosphere, breaking down ozone molecules.
Antarctica’s extreme cold temperatures and unique atmospheric conditions caused a more intense depletion of the ozone layer, especially during the Southern Hemisphere's spring. Susan Solomon was one of the first scientists to gather crucial evidence of this depletion in 1986. This led to the Montreal Protocol in 1987, where 197 countries and the EU committed to phasing out ozone-depleting substances like CFCs.
For years, scientists noticed the ozone hole was shrinking, but the unpredictable variability of the atmosphere made them cautious in confirming the recovery. With 15 years of data now at hand, researchers are confident that the ozone layer is indeed bouncing back. If the current trend continues, scientists predict the ozone layer could fully recover in around 10 years.
Solomon remains hopeful: "By 2035, we might see a year with no ozone hole at all. It will be exciting, and some of you will witness this recovery in your lifetimes. And that is something humanity achieved together."
