Powell served 12 years on the National Science Board and recently retired as executive director of Graduate Fellowships for Science, Technology, Engineering, and Mathematics Diversity. His book, Night Comes to the Cretaceous, explores the scientific debate regarding dinosaur extinction. In Four Revolutions in the Earth Sciences, Powell addresses dinosaur extinction in addition to three other scientific debates: deep time, continental drift and global warming. Powell has posited that the scientific consensus on global warming nears universality and he actively counters climate change denialism in his research and other publications.
