A recent study by these scientists identified a new, natural source of carbon dioxide emissions into the atmosphere—a region in Africa where the splitting apart of the continental crust opens many fractures in the Earth that release the gas. The research team includes master’s student Nicole Thomas, Professor Tobias Fischer, and Ph.D. student Hyunwoo Lee, from the University of New Mexico.
