It was caused by chlorofluorocarbons (CFCs) and other man-made chemicals used in aerosols, fridges, and air conditioners. The problem made headlines in the ’80s and ’90s — especially after the 1985 discovery of the Antarctic ozone hole. It triggered a rare moment of global unity. In 1987, world governments signed the Montreal Protocol, agreeing to phase out CFCs and other ozone-depleting substances. It’s often cited as the most successful environmental treaty in history. Every single UN member state signed it. Did It Work? Yes, it really did according to the United Nations and World Meteorological Organization (WMO). The ozone layer has been steadily recovering since the early 2000s. If current policies stay in place, it’s expected to return to 1980 levels by around 2040 globally, and by 2066 over Antarctica, where the damage was worst. The “hole” still appears seasonally over Antarctica, but it’s been shrinking in both size and duration. Some years (like 2020 and 2023) saw unusually large holes due to volcanic eruptions or wildfires, which can temporarily worsen ozone loss — but these are short-term blips.
