Bill Nye sought to burn any would-be presidents in an Earth Day interview in which he panned all three Republican presidential candidates for being “in denial about climate change.”

“There’s still a very strong contingent of people who are in denial about climate change,” Nye said in an interview with CNN published Friday. “And if you don’t believe me, look at the the three people currently running for president of the world’s most influential country who are … climate change deniers.”
