Geologists, biologists and other scientists convened this week in Paris to discuss fungus stains that threaten France’s prehistoric Lascaux cave drawings. Black stains have spread across the cave’s murals of bulls, felines and other images, and scientists have been hard-pressed to halt their creep.
Rising temperatures have complicated matters by stopping air from circulating inside the caverns, said Marc Gauthier, who heads the Lascaux Caves International Scientific Committee.
