Mario Molina

Historical

Mar 19, 1943

Oct 7, 2020

Mario Molina was a chemist of Mexican origin who provided the world with a wealth of knowledge about ozone thanks to his research on the impact of chlorofluorocarbons or CFCs. Molina was born in Mexico City in 1943, and early, he was interested in sciences. He turned his family's bathroom into a laboratory to pursue his dream. His aunt Esther Molina, a professional chemist, encouraged him to develop his passion for science. At 11, he was sent to school in Switzerland, where he learned German and developed an interest in chemistry, though he once wanted to be a musician. Molina returned to Mexico and did his first degree in chemical engineering at the National Autonomous University of Mexico (UNAM). He then went to Germany for further studies, after which he joined the University of California in Berkeley to undertake a Ph.D. in physical chemistry. During his time at Berkeley, Molina was under the supervision of Professor George C. Pimentel; he learned more about molecular dynamics and chemical reactions. However, his career improved when he moved to F. Sherwood Rowland as a postdoctoral fellow at the University of California at Irvine. Collectively, they studied the environmental behavior of CFCs and thus found the CFC-ozone depletion hypothesis. In 1974, Molina and Rowland provided the world with a paper outlining how industries that used CFCs were eradicating the ozone layer. This brought awareness worldwide, and later, the Montreal Protocol, an agreement to ban the use of CFCs. Molina's work brought him, Rowland, and Paul Crutzen the 1995 Nobel Prize in Chemistry. In his subsequent years of practice, Molina paid much attention to atmospheric chemistry, advancing on climate change and air quality, mainly in Mexico City. He died in 2020, but he will be remembered as a great contributor to the field of environmental science.

Life and achievements

Early life

Mario Molina was born to a wealthy and academic family on March 19, 1943, in Mexico City, Mexico. His father was a lawyer and diplomat, while his mother was a homemaker. Unlike other families that had laid down career patterns that a child was expected to follow, Molina had developed an interest in science from childhood. In childhood, he turned the bathroom into a laboratory where he used toy microscopes and chemistry sets to conduct experiments. Being a professional chemist, his aunt Esther Molina insisted on his desire and helped him to progress to more complex experiments. When Molina was 11, he started attending a boarding school in Switzerland and learned German there. He did like the idea at first but changed his mind when he got into class and saw that his classmates were not as enthusiastic about science as he was. However, studying at the University in England was vital for him as it helped him to become a chemist. After returning to Mexico, he attended the National Autonomous University of Mexico (UNAM), where he took a chemical engineering course that was flexible enough to follow his passion for physical chemistry. Molina's academic adventure led him to Germany, where he researched polymerization kinetics at the University of Freiburg. But then he discovered he was more interested in atmospheric chemistry, so he headed to the United States. He received his Ph.D. in physical chemistry from the University of California at Berkeley in 1972 under the supervision of George Pimentel. For this reason, Molina's early academic experiences can be regarded as the background for his subsequent work in environmental chemistry and his groundbreaking investigations of the depletion of the ozone layer.

Legacy

Mario Molina's work and achievements are best remembered through his work in destroying the ozone layer and as an environmentalist. His work not only contributed to the enhancement of scientific knowledge in the field of atmospheric chemistry but also made a peculiar contribution to the development of global environmental policy. Molina's scientific work with Sherwood Rowland explained that CFCs, used in such products as refrigerators and aerosol sprays, destroy the ozone layer, which helps shield life on the Earth from dangerous ultraviolet radiation. They were found, and this led to the signing of the 1987 Montreal Protocol, an agreement that aimed at eliminating the use of CFCs and other ozone-depleting substances. Molina's work is much more than his Nobel Prize-helpful research on chemical reactions and atmospheric gases. In his career, he was always on record, especially in supporting the formulation of environmental policy based on science. He devoted much time to explaining the risks of ozone depletion to the community and political leadership because he knew that citizens and governments had an essential role in tackling global environmental issues. His efforts made a paradigm shift and created a global opinion on how best to cooperate to safeguard the environment, not only on topics such as climate change. Molina's contribution to environmental science and policy persisted in the 21st century. He was in the climate change research team, where he specialized in air quality and the effects of urbanization on the environment. This was evident in his endeavors in Mexico City, where he contributed to measures for combating airborne pollution. Molina was also active in climate change talks and underlined the need to act quickly to tackle climate change. He has made significant contributions to science and policy, shaping the world and influencing generations of scientists and environmentalists.
