“Scientists had theorized since the 1970s about the chemistry that could lead to ozone depletion.
But in May 1985 scientists with the British Antarctic Survey shocked the world when they announced the
discovery of a huge hole in the ozone layer over Antarctica.”

“"If we had just kept letting CFCs increase at a pretty nominal rate, characteristic of the 1970s,
the decreased ozone levels of the hole would have eventually covered the entire planet,"
said atmospheric physicist Paul Newman of NASA's Goddard Space Flight Center.”

“The discovery of the Antarctic ozone hole shocked the scientific world when it was discovered in 1985,
and research provided the underpinning for a landmark global agreement to mitigate the emissions of ozone-depleting
chlorofluorocarbons and bromocarbons that were responsible.”
