Bill Nye Says Climate Change Deniers Have a Bad Case of Cognitive Dissonance

For some reason, certain people just don't believe it's real. Even Scott Pruitt, the man President Trump named to head the Environmental Protection Agency, isn't steadfast about global warming and what causes it. But years of scientific study have shown the planet is getting warmer. According to Bill Nye, the answer is simple: cognitive dissonance. "People have a certain worldview; [then] they're confronted with evidence that conflicts with the worldview, so they have dissonance, conflict in their minds," Nye says.
