Texas Sen. Ted Cruz appeared on the CNBC show Squawk Box, where he discussed the basis for his skepticism of climate science.

“I’m old enough to remember back in the 1970s when there were a bunch of left wing scientists and politicians who said there was global cooling,” Cruz said. “Suddenly the theory transmogrified from global cooling into global warming. Exact same people and by the way, their solution was identical. They want control over your lives. When the evidence didn’t back that up, did you notice that the theory changed a third time? Now it’s not global warming. That’s not the chic way to put it. It’s climate change.”

“Climate change is the perfect pseudo-scientific theory for a power hungry politician because it can never be disproven,” Cruz continued. “The climate’s always changing and the solution is identical… massive government control over the economy.”

When asked what can be done about emissions controls and the manner in which the EPA approaches the issue, Cruz replied: “There is a perfectly legitimate and important role for the EPA in government: to keep the air and water clean… that’s what we should be doing with the environment. But I tell you, carbon dioxide is not a pollutant.”

“The effect of these massive regulations being pushed by Obama and Hillary Clinton is to drive up the costs of living,” he said. “The cost of living is going up dramatically and you can’t afford it. Should we keep the air and water clean? Absolutely. But we shouldn’t be driving costs up on people who are struggling.”
