Scientists say the hole in the Earth’s protective ozone layer over the Southern Hemisphere is larger than usual this year and already surpasses the size of Antarctica.
The European Union’s Copernicus Atmosphere Monitoring Service said Thursday that the so-called ozone hole, which appears every year during the Southern Hemisphere spring, has grown considerably in the past week following an average start.
“Forecasts show that this year´s hole has evolved into a rather larger than usual one,” said Vincent-Henri Peuch, who heads the EU's satellite monitoring service.
“We are looking at a quite big and potentially also deep ozone hole,” he said.
Atmospheric ozone absorbs ultraviolet light coming from the sun. Its absence means more of this high-energy radiation reaches the Earth, where it can harm living cells.
Peuch noted that last year's ozone hole also started out unremarkably but then turned into one of the longest-lasting ones on record.
The Montreal Protocol, signed in 1987, led to a ban on a group of chemicals called halocarbons that were blamed for exacerbating the annual ozone hole.
Experts say that while the ozone layer is beginning to recover, it's likely to take until the 2060s for the ozone-depleting substances used in refrigerants and spray cans to completely disappear from the atmosphere.
