Bill Nye, known for his 1990’s science kid’s show who has since become an outspoken advocate on “climate change,” accused CNN of doing a “disservice” to its audience on Saturday by having a real scientist on their network to discuss climate change.

The CNN “New Day Saturday” panel, which included Nye and William Happer, a physicist at Princeton University,” became heated after Happer said the climate change that Nye talks about is a “myth.”

“There’s this myth that’s developed around carbon dioxide that it’s a pollutant, but you and I both exhale carbon dioxide with every breath. Each of us emits about two pounds of carbon dioxide a day, so are we polluting the planet?” Happer, who has advised President Donald Trump on climate issues, said.

“Carbon dioxide is a perfectly natural gas, it’s just like water vapor, it’s something that plants love. They grow better with more carbon dioxide, and you can see the greening of the earth already from the additional carbon dioxide in the atmosphere,” he explained.

Nye hit back and said Happer didn’t understand the “rate,” or speed at which carbon dioxide is entering the atmosphere. Then he ripped CNN for not having only climate change alarmists on their network.

“And I will say, much as I love the CNN, you’re doing a disservice by having one climate change skeptic and not 97 or 98 scientists or engineers concerned about climate change,” Nye said.

When asked why he’s a skeptic, Happer — a real scientist — explained that climate change alarmism is built on a dishonest foundation.

“Let me point out that science is not like passing a law,” he said. “You don’t have a vote to say how many are for the law of gravity and how many are against — it’s based on observations. And if you observe what’s happening to, for example, the temperature, the temperature is not rising nearly as fast as the alarmist computer models predicted. It’s much, much less — factors of two or three less. So the whole basis for the alarmism is not true, it’s based on flawed computer modeling.”
