For his 8th birthday, young Mario Molina got a microscope, which launched a career in science. His interest in chemistry led to a doctorate and work on the atmosphere. In an epilogue by Mario, the Mexican-born chemist declares he has now taken on global warming. Additional back matter adds even greater interest in this accessible and appealing biography. The book is also available in Spanish: Mario y el agujero en el cielo: Cómo un químico salvó nuestro planeta (opens in a new window).
