What does Mario Molina do?
Chemist
Why did Mario Molina won the Nobel Prize?
The Nobel Prize in Chemistry 1995 was awarded jointly to Paul J. Crutzen, Mario J. Molina and F. Sherwood Rowland “for their work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone.”
Where did Mario Molina do his work?
Molina worked in the Jet Propulsion Laboratory at the California Institute of Technology in Pasadena from 1982 to 1989, when he became a professor at the Massachusetts Institute of Technology in Cambridge. In 2004 he moved to the University of California, San Diego.
What challenges did Mario Molina face?
In 1974, Mario Molina and Sherwood Rowland demonstrated that CFC gases, freons, have a damaging effect on ozone in the atmosphere. Freons had many uses, including propellants in spray cans and refrigerants in refrigerators. By limiting the use of freons, the depletion of the ozone layer has been slowed.
Who did Mario Molina marry?

What college did Mario Molina go to?
University of California, Berkeley1968–1972
Is Mario Molina dead?
Deceased (1943–2020)
Where is Mario Molina from?
Mexico City, Mexico
How old is Molina?
77 years (1943–2020)
What did Rowland and Molina do?
Sherwood Rowland and Mario J. Molina discovered that chlorofluorocarbons (CFCs) could deplete Earth’s atmospheric ozone layer, which blocks the sun’s damaging ultraviolet rays. When the scientists reported their findings in 1974, CFCs were widely used as refrigerant gases and as propellants in aerosol sprays.
Is a Nobel laureate of 1995?
The Nobel Peace Prize 1995 was awarded jointly to Joseph Rotblat and Pugwash Conferences on Science and World Affairs “for their efforts to diminish the part played by nuclear arms in international politics and, in the longer run, to eliminate such arms.”
How did Mario Molina change the world?
Mario Molina (1943–2020) was the first to realize that chlorofluorocarbons (CFCs) could destroy ozone. In the two decades following his discovery, he and his mentor became voices alerting the world to the danger of CFCs and ozone depletion. Their warnings often fell on deaf ears.
Why is the ozone layer a problem?
Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.
Does greenhouse gas destroys the ozone layer?
Emissions of greenhouse gases can affect the depletion of the ozone layer through atmospheric interaction. The increase in CH4 emissions in the same period changes this ozone depletion by +1.4% per decade to -4.4% per decade, which is close to TOMS and Dobson measurements.
