Mario J. Molina

Mario J. Molina was a prominent scientist known for his groundbreaking research on the depletion of the ozone layer caused by chlorofluorocarbons (CFCs), chemicals used in aerosols and refrigerators. His work demonstrated how these substances can damage the atmosphere, leading to increased levels of harmful ultraviolet radiation reaching the Earth's surface. Molina's findings were crucial in shaping environmental policies, contributing to the global agreement called the Montreal Protocol, which aimed to phase out CFCs. His contributions significantly advanced our understanding of atmospheric chemistry and its impact on climate and human health, earning him a Nobel Prize in Chemistry in 1995.
