Former Alaska Gov. Sarah Palin (R) accused “Science Guy” Bill Nye of being an alarmist concerning global warming during an appearance on Capitol Hill, The Hill reported.

“Bill Nye is as much a scientist as I am,” Palin said during a screening of Climate Hustle, a documentary by noted climate change-denier Marc Morano. “He’s a kids’ show actor, he’s not a scientist.”

The remarks came shortly after Nye accused Morano of falsely claiming that Nye denied his invitation to take part in a May 2 panel discussion alongside Palin.

According to Nye, Morano never invited him at all, but did interview him. Footage from that discussion is reportedly included in Morano’s film, including Nye’s call for organizations making a living denying global warming.

“I can see where people are very concerned about this and are pursuing criminal investigations as well engaging in discussions like this,” Nye reportedly says in the film. “They’re keeping us from getting to work, they’re holding us back.”

Palin, who has advocated for increases in drilling for oil and natural gas, responded by saying, “Some people would say I’m pushing progress and development too aggressively, certainly not holding anybody back, I want people to work, I want people to produce.”

However, the former vice-presidential candidate’s accusations regarding Nye’s background do not hold up. Nye earned a Bachelors of Science from Cornell University, where he studied mechanical engineering. He has also served as both the vice-president and executive director of the Planetary Society, and was part of the design team behind sundials that were used in Mars Exploration Rover missions.
