September's ozone hole was the biggest in 20 yearsScientists say unusual atmospheric conditions helped make this season's Antarctic ozone hole especially large.- 🌏 The seasonal hole in the ozone layer above Antarctica grew unusually large this September.
- 🛡️ Ozone high in the atmosphere acts like sunscreen by blocking much of the Sun's harmful ultraviolet light.
- 🌬️ Cold temperatures and strong winds helped create conditions that damaged more ozone.
- 📡 Scientists had noticed warning signs months earlier and tracked the changes with satellites and balloons.
- 🌱 Global rules have reduced ozone-damaging chemicals, but the layer still needs many years to recover fully.
🛡️ Fun Fact!
Most ozone is found 15 to 35 kilometres above Earth. If all of it were brought down to sea level, it would form a layer only about three millimetres thick!
