Bill Nye Can't Save the World All by Himself

Mr. Nye is not wrong about the science involved in the political and social issues he is tackling. Climate change is real and it is getting worse. The strain the human population is putting on sensitive ecosystems is beyond debate. Science continues to discover fascinating complexity in human sexuality and piles of evidence show us that vaccines save vulnerable lives. But too often Mr. Nye's humor and wit seem meant to prove that people who disagree with him just need to understand the science more clearly.
