Molina and American scientist Frank Sherwood Rowland printed a paper in 1974 that discovered chlorofluorocarbons (CFCs), chemical substances utilized in quite a lot of merchandise, have been destroying the ozone layer.

The groundbreaking research was lambasted by the chemical substances business, nevertheless it opened the general public’s eyes to the dangerous results of CFCs and led on to the Montreal Protocol.

Molina labored behind the scenes to draft the treaty, which phased out CFCs around the globe and has since turn out to be probably the most profitable worldwide effort to combat local weather change and environmental degradation.

“It is a planet-saving treaty, defending each the ozone layer and the local weather system,” wrote Molina.

The hanging factor about Molina, Zaelke mentioned, is that he was a consummate gentleman, regardless of being “vilified” by the chemical substances business for years after he first printed his ozone analysis.

“All through this, Mario by no means, by no means modified his willingness to combat and his willingness to stay a gentleman. That is who he was,” Zaelke mentioned. “He would have been a superb diplomat if he had chosen that as a profession.”

Molina earned his Ph.D. from the College of California, Berkeley, in 1972 and in later years rejoined the identical system as a professor on the College of California, San Diego.

He was a outstanding determine within the scientific and political worlds in Mexico and america. Molina was a member of the Nationwide Academy of Sciences and served on the Nationwide Fee on Vitality Coverage.

Zaelke mentioned Molina was nonetheless working up till his final days. The pair had simply gotten an op-ed permitted when Zaelke heard about Molina’s loss of life.
