Presidential hopeful Sen. Ted Cruz took to the airwaves in an interview with Glenn Beck this week. “Climate change is not science,” Cruz told Beck in the interview. “It’s religion. Look at the language where they call you a denier.”

“Any good scientist is a skeptic,” Cruz said. “If he’s not, he or she should not be a scientist.”

In the second Republican debate, Cruz volunteered himself as a climate skeptic to CNN moderator Jake Tapper.
