In 1955 Paul Crutzen, Mario Molina and Sherwood Rowland were awarded the #NobelPrize in Chemistry for helping us understand why the ozone layer was disappearing. #OTD in 1987, nations signed the Montreal Protocol to help us protect it. GIF: NASA/NASA Ozone Watch/Katy Mersmann
#OTD in 1987, Pres. Reagan signs the Montreal Protocol, joining int'l partners in first efforts to protect the ozone layer. The Protocol has been repeatedly strengthened by controlling add'l ozone-depleting substances and adjusting dates controlled substances are phased out.
In 1985, the world’s governments adopted the Vienna Convention for the Protection of the Ozone Layer. Under the Convention’s Montreal Protocol, governments, scientists and industry worked together to cut out 99 per cent of all ozone-depleting substances

Persistent pollutants and the unintended side effects of the Montreal Protocol
Emissions from eastern China account for at least 40–60% of the global rise in trichlorofluoromethane (CFC-11) emissions since 2013, according to a Nature study. This rise is contrary to the Montreal Protocol agreement to phase out CFC production and use.
It’s the 30th anniversary of the Montreal Protocol to protect the ozone layer. and work together to study atmospheric ozone.

Earth’s ozone layer would have collapsed by 2050 with catastrophic consequences without the Montreal Protocol
