"New Ozone-Depleting Gases Found in Atmosphere"

"Scientists have found four new ozone-destroying gases in the atmosphere, most likely put there by humans in the last 50 years, despite a ban on these dangerous compounds."

"It is the first time since the 1990s that new substances damaging to Earth's stratospheric shield have been found, and the experts believe there may be more out there.

“Our research has shown four gases that were not around in the atmosphere at all until the 1960s, which suggests they are manmade,” wrote the team from Europe and Australia in the journal Nature Geoscience."
