So today, we're gonna look at how wrong he is on the climate.
He's been fact-checked by CBS:
CRUZ: "The satellites that actually measure the temperature, that we've launched into the air to measure the temperature, they have recorded no significant warming whatsoever for the last 18 years."And factcheck.org:
THE FACTS: Scientists, including those who work with the very satellite measuring system that Cruz refers to, say he's misusing the satellite data. They do show warming, albeit relatively little over the period Cruz cites, says Carl Mears, senior scientist for Remote Sensing Systems, which produces the data that Cruz refers to.
But by starting his comparison period in 1997, Cruz has selected a time when temperatures spiked because of an El Nino weather pattern. Starting at an artificially high point minimizes the rate of increase since then, Mears said, adding, "If you start riding your bike at the top of a big hill, you always go downhill, at least for a while."
More important is what's measured at the Earth's surface, where people live, Mears said. Those ground-based systems show a greater degree of warming.
The long-term trend that Mears' satellites show is about 0.7-degree warming since 1979, when satellites started measuring temperature. Ground-based monitors show a warming of about 1 degree during the same period. And 1979 was not among the top five hottest or coldest years in the 36 years of records.
As for Cruz’s claim that “climate change is the perfect pseudoscientific theory because it can never, ever, ever be disproven,” Mann told us that “absolutely” climate change could be disproved. “That’s true in any area of science,” he said. “It’s true in physics. It’s true in biology. It’s true in climate change.” As he explained above, the theory of climate change rests upon the accuracy of the theory of global warming, which, in turn, depends on the theory of the greenhouse effect.And a fact-check from the Chicago tribune even showed up at the libertarian-lovin' Reason.com:
One way to disprove climate change might be to disprove the greenhouse effect, Mann told us. This would entail finding strong evidence that suggests gases like carbon dioxide don’t trap the sun’s heat. But the likelihood of this occurring is slim to none, as the theory has been verified time and again since it was first proposed by the physicist Joseph Fourier in 1824.
In fact, Mann says, “things as basic as the design of heat-seeking missiles rely upon an understanding of the greenhouse effect.”
Another way to disprove climate change would be to challenge the theory of global warming, adds Mann. Since global warming can be thought of as an enhanced greenhouse effect (see NASA’s definition of the term here), this method of falsification would be related to — though different from — disproving the greenhouse effect.
In other words, instead of finding strong evidence that suggests carbon dioxide, for example, doesn’t trap the sun’s heat point blank, scientists would have to show that higher average global temperatures aren’t the result of increased levels of greenhouse gases. But scientists have found no evidence to support this claim.
The topic was global warming. Every major scientific body has confirmed its existence, but as "the son of two mathematicians and computer programmers and scientists," he feels particularly qualified to debunk it.And this is the guy the merely moderately crazie Republicans want instead of the billionaire bigot, Donald Trump.
"The scientific evidence doesn't support global warming," he informed NPR. "For the last 18 years, the satellite data—we have satellites that monitor the atmosphere. The satellites that actually measure the temperature showed no significant warming whatsoever."
There are two flaws in his argument. The first is that satellite data are not the only scorecard. Records of surface temperatures, for example, show that "warming during the first 15 years of the 21st century is at least as great as the last half of the 20th century," according to a study by scientists at the National Oceanic and Atmospheric Administration.
The second is that the satellite data don't refute global warming. NASA says that based on surface temperatures, 2014 was the warmest year on record. Based on satellite data, it was the third-warmest.
The same data indicate that of the 14 hottest years ever, 13 occurred in this century. When Cruz says there has been "no significant warming" since 1997, he's engaging in brazen deception.
