Watch: Bill Nye blows gasket when a real scientist schools him on facts about 'climate change

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."

Nye, who is not a real scientist, immediately shot back at Happer.

"That’s completely wrong," Nye shot back. "He’s cherry picking a certain model. The heat ended up in the ocean. This is not controversial in mainstream science, everybody."

Nye added that he "encourages" everyone to look at the facts. For years, climate change alarmists said the polar ice caps would melt completely by the mid-2010's causing the sea levels to rise by meters, which would then put low-lying coastal areas across the world under water. None of these things ever happened. In fact, ocean waters have not warmed on an overall average basis, despite claims made by people like Nye and former Vice President Al Gore.

Not only that, but a recent National Oceanic and Atmospheric Administration, the government agency that monitors the climate, whistleblower said the agency for years manipulated climate data for political reasons — meaning to show that climate change is happening when it really isn't.

Still, Nye spouted his talking points and lectured Happer for being a "climate change denier."

He said:

I encourage you to cut this out so we can move forward and make the United States a world leader in technology. We want advanced wind turbines...advanced concentrated energy plants. If we were to do that, we would have at least 3 million new jobs in the United States that could not be outsourced. We would not need to have our military on the other of the world defending what people call "our oil." We could move forward and we could export this technology. We could be world leaders in this instead of wringing our hands and cherry picking data and pretending that this problem that’s obvious to the scientific community but it is somehow not obvious to you.

Later in the interview, Happer said the Trump administration should back out of the 2016 Paris Agreement, a global agreement made last year on greenhouse gas emissions. Happer compared the agreement to former British Prime Minister Neville Chamberlain's appeasements of Germany dictator Adolf Hitler in 1938, known as the Munich Agreement.

That agreement allowed Hitler to take over territory in what was then Czechoslovakia known as the "Sudetenland." Hitler said he wanted the territory because it was occupied mainly by Germans and Austrians. We now know, however, that it was just one more step in Hitler's plan to begin conquering Europe.

The comparison Happer made stunned Nye and the CNN hosts, who demanded that Happer explain his comparison.

"It is an appropriate comparison because it was a treaty that was not going to do any good," Happer explained. "This treaty also will not do any good. Anyone who looks at the results of doing what the treaty says can see that the effect on the earth’s climate is — even if you take the alarmist computer models trivial — it will not make any difference and yet it will cause enormous harm to many people."

The contentious exchange came on "Earth Day 2017," also the same day that people across the world were marching "for science."
