Reaching out in an interdisciplinary direction, the Royal Swedish Academy of Sciences has awarded the 1995 Nobel Prize in Chemistry to Paul Crutzen, Mario Molina and F. Sherwood Rowland for “their work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone.” The award comes on the eve of the 1996 global ban on ozone‐depleting chemicals, mandated by the 1987 Montreal Protocol and its later updates.
