Finally, some good news about the environment. Earlier this week, the United Nations announced in a report that the ozone layer is on the mend. If the current recovery rate continues, parts of the ozone could be fully repaired by the 2030s. The entire layer — even the highly damaged parts over the North Pole and South Pole — could be completely healed by 2060.

The study, Scientific Assessment of Ozone Depletion: 2018, monitors ozone recovery, and it is the latest in a series of reports that the UN releases every four years. This year, it shows that the ozone has been recovering at a steady rate of 1 to 3 percent since 2000 because of the global efforts made to reduce CFCs and other ozone-depleting chemicals.

Over the past few decades, humans have done significant damage to the ozone layer, which protects life on Earth from the sun’s harmful ultraviolet rays. But through global agreements like the 1987 Montreal Protocol, we have made huge steps toward healing it. The protocol mandated that countries phase out chlorofluorocarbons (CFCs) and other ozone-depleting chemicals. The EPA has described it as the most successful environmental global action in history, with 197 countries signing the agreement.

“If ozone-depleting substances had continued to increase, we would have seen huge effects. We stopped that,” said Paul Newman, a NASA scientist and co-chairman of the new UN report. Newman added that if we hadn’t made these changes, two-thirds of the ozone layer would have been destroyed by 2065.

Scientists have cautioned against claiming victory too soon. Banned CFC emissions are increasing in China, but the Chinese government has promised to fix the problem. Newman said we need to wait until 2060, and let our grandchildren do the celebrating.

Still, these recent findings could help contribute to future climate action. In 2019, the Montreal Protocol is set to be enhanced with the Kigali Amendment, which hopes to tackle climate change by targeting greenhouse gases used in air conditioning and refrigeration.
