Ted Cruz Owns Sierra Club President Aaron Mair on Global Warming

Senator Ted Cruz questioned Aaron Mair, the president of the climate change extremist organization, The Sierra Club, during a Judiciary Subcommittee hearing last week.

Senator Cruz questioned Mair about a portion of his written statement in which he said the science behind climate change and its effect on minority communities “should not be up for debate.”

Cruz asked, “I’m curious is the Sierra Club, is this a frequent practice to declare areas of science not up for debate, not up for consideration of what the evidence and data show?”

Over and over, Mair repeated the debunked “fact” that 97% of the climate change scientists believe the earth is heating up and the science is settled.

I heard a story that back when Pythagoras was around, about 97% of the scientists said the earth was flat. Same thing when Galileo was trying to convince people the earth moved around the sun, 97% of the scientists said it wasn’t true!

The assertion that 97% of scientists believe that climate change is a man-made, urgent problem is a fiction. The so-called consensus comes from a handful of surveys and abstract-counting exercises that have been contradicted by more reliable research.

Of the various petitions on global warming circulated for signatures by scientists, the one by the Petition Project, a group of physicists and physical chemists based in La Jolla, Calif., has by far the most signatures—more than 31,000 (more than 9,000 with a Ph.D.). It was most recently published in 2009, and most signers were added or reaffirmed since 2007. The petition states that “there is no convincing scientific evidence that human release of . . . carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate.”


The 97% claim reported the results of a two-question online survey of selected scientists. Mr. Doran and Ms. Zimmerman claimed “97 percent of climate scientists agree” that global temperatures have risen and that humans are a significant contributing factor.

The survey’s questions don’t reveal much of interest. Most scientists who are skeptical of catastrophic global warming nevertheless would answer “yes” to both questions. The survey was silent on whether the human impact is large enough to constitute a problem. Nor did it include solar scientists, space scientists, cosmologists, physicists, meteorologists or astronomers, who are the scientists most likely to be aware of natural causes of climate change.

The 97% number was created by meticulously selecting certain surveys using murky terminology to formulate a specific narrative.The media has also completely failed to report the existence of many studies showing that a majority of scientists are skeptical of man’s connection to global warming.  It may be difficult for some to admit it, but the jury is still out.

It also failed to address the fact that a sample size of only 200 self proclaimed scientist doesn’t even remotely form a 97% consensus among the thousands of scientists who have weighed in on the subject and NOT CALCULATED IN THAT 97%.

  1. Are you aware that the Global Warming Petition Project allowed anyone with a BSc or higher in their selected fields to sign, regardless of whether that individual had any authentic expertise or not? So a stay-at-home mom with a bachelor’s degree in biology who has never used that degree and never worked in a climate-related field is considered to have an informed opinion, when in fact this hypothetical person is not at all informed. Obviously the GWPP’s criteria are overly broad.

    Yet even if we give the GWPP the greatest benefit of the doubt possible, comparing the number of signers to the number of people who have those degrees (per US Department of Education data for the degrees in question between 1970 and 2013) reveals that the GWPP signers represent just one quarter of one percent (0.25%) of the people who could have signed the petition. And comparing the GWPP signers to the number of people who actually worked in those fields (per Bureau of Labor Statistics data for 2013) shows that the signers represent less than one half of one percent (0.44%) of the people who could have signed the petition.

    So even if you reject the many studies that have all found overwhelming consensus that climate change is happening, that it’s largely driven by industrial emissions of greenhouse gases, and that it’ll be disruptive to global ecology and society (Doran & Zimmerman 2009, Anderegg et al 2010, Cook et al 2013, Stenhouse et al 2013, Verheggen et al 2014, and recently Carleton et al 2015, each of which used different methodologies to test the robustness of the consensus), the GWPP doesn’t disprove anything.
