A Real Climate Scientist Demolishes Bill Nye’s Global Warming Alarmism
All right, this one is a bit old—from last year even. That aside, I want to thank whoever posted this on Facebook for me to pick up. The truth be known, Facebook is a prime source of story ideas for this blog.
And this is refreshing. For once I’m not having to explain some fact-deprived meme from The Comical Conservative. This time we have Dr. Roy Spencer, an actual climate researcher, weighing in. And he has much to say about the evidence. Actually, he doesn’t. At least in the YouTube clip he doesn’t. Additionally, the item posted by Austin Peterson on The Libertarian Republic presents little in the way of evidence, either for or against the case for anthropogenic global warming (AGW). But Spencer is a real scientists working in the field, and it is worth knowing what he had to say in the interview.
Global warming alarmist talking heads like Bill Nye, Neil deGrasse Tyson and Al Gore are constantly paraded around as experts on climate.
I hope not. Because none of the three do research related to climate, and nobody would seriously refer to them as experts. What they happen to be are public defenders of the science behind AGW—speakers, if you like. In fact, you can discount Vice President Al Gore right off the bat, because his expertise is politics, and his training in serious science is close to vacant.
On the other hand, Bill Nye and Neil deGrasse Tyson have taken some college courses—Tyson more so—in physics, and the science of physics lies at the base of the study of AGW. In full disclosure, I have had college courses in physics, including four in the critical field of thermodynamics, and it is from this background that I come to agree with the argument for AGW.
To be sure, Dr. Roy Spencer has had these courses, and beyond that he has degrees in atmospheric science, including a Ph.D. in meteorology from the University of Wisconsin–Madison. The Wikipedia entry for Roy Spencer lists a number of peer-reviewed papers critical of AGW, such as this one:
In 2007, Spencer and others published a paper in Geophysical Research Letters regarding negative cloud feedback in the tropics that potentially supports Richard Lindzen‘s Iris hypothesis, which proposes that as the tropical atmosphere warms, cirrus clouds decrease, allowing infrared heat to escape from the atmosphere to outer space. Spencer stated, “To give an idea of how strong this enhanced cooling mechanism is, if it was operating on global warming, it would reduce estimates of future warming by over 75 percent. […] Right now, all climate models predict that clouds will amplify warming. I’m betting that if the climate models’ ‘clouds’ were made to behave the way we see these clouds behave in nature, it would substantially reduce the amount of climate change the models predict for the coming decades.
This paper is available on-line from the American Geophysical Union, and I have retained a copy for your viewing:

Spencer’s objections to AGW, based on publication topics, appear to be related to the effects of clouds on solar energy loss. Some of his publications have received major push-back from other scientists. Of note is a recent work published in 2011 with William Braswell:
In 2011, Spencer and Braswell published a paper in Remote Sensing concluding that more energy is radiated back to space and released earlier than previously thought. Spencer stated, “The satellite observations suggest there is much more energy lost to space during and after warming than the climate models show. There is a huge discrepancy between the data and the forecasts that is especially big over the oceans.”
The paper was criticized by numerous climate scientists. Kerry Emanuel of MIT, said this work was cautious and limited mostly to pointing out problems with forecasting heat feedback.
The editor-in-chief of Remote Sensing, Wolfgang Wagner, later resigned over publication of Spencer and Braswell (2011), stating, “From a purely formal point of view, there were no errors with the review process. […] the problem I see with the paper by Spencer and Braswell is not that it declared a minority view …but that it essentially ignored the scientific arguments of its opponents. This latter point was missed in the review process, explaining why I perceive this paper to be fundamentally flawed and therefore wrongly accepted by the journal.” Wagner added he, “would also like to personally protest against how the authors and like-minded climate sceptics have much exaggerated the paper’s conclusions in public statements”.
Spencer responded that Wagner’s assertion was wholly inaccurate, “But the paper WAS precisely addressing the scientific arguments made by our opponents, and showing why they are wrong! That was the paper’s starting point! We dealt with specifics, numbers, calculations…while our critics only use generalities and talking points. There is no contest, as far as I can see, in this debate. If you have some physics or radiative transfer background, read the evidence we present, the paper we were responding to, and decide for yourself.”
Andrew Dessler later published a paper opposing the claims of Spencer and Braswell (2011) inGeophysical Research Letters. He stated, among other things:
First, [they] analyzed 14 models, but they plotted only six models and the particular observational data set that provided maximum support for their hypothesis. Plotting all of the models and all of the data provide a much different conclusion.
At the very least, Spencer’s methods indicate a lack of scientific rigor. I went into this with the possibility of finding an additional factor, that factor being denial of AGW is strongly linked with political alignment and to a lesser degree with religiosity. Spencer’s Wikipedia contains two notes pointing toward religious influence:
Spencer is a signatory to An Evangelical Declaration on Global Warming, which states that “We believe Earth and its ecosystems—created by God’s intelligent design and infinite power and sustained by His faithful providence —are robust, resilient, self-regulating, and self-correcting, admirably suited for human flourishing, and displaying His glory. Earth’s climate system is no exception. Recent global warming is one of many natural cycles of warming and cooling in geologic history.”. He believes that most climate change is natural in origin, the result of long-term changes in the Earth’s albedo and that anthropogenic greenhouse gas emissions have caused some warming, but that its warming influence is small compared to natural, internal, chaotic fluctuations in global average cloud cover. This view contradicts the scientific consensus that “most of the warming observed over the last 50 years is attributable to human activities”.
And:
In TCS Daily, Spencer wrote, “Twenty years ago, as a PhD scientist, I intensely studied theevolution versus intelligent design controversy for about two years. And finally, despite my previous acceptance of evolutionary theory as ‘fact,’ I came to the realization that intelligent design, as a theory of origins, is no more religious, and no less scientific, than evolutionism. In the scientific community, I am not alone. There are many fine books out there on the subject. Curiously, most of the books are written by scientists who lost faith in evolution as adults, after they learned how to apply the analytical tools they were taught in college.” In the book The Evolution Crisis, Spencer wrote, “I finally became convinced that the theory of creation actually had a much better scientific basis than the theory of evolution, for the creation model was actually better able to explain the physical and biological complexity in the world. […] Science has startled us with its many discoveries and advances, but it has hit a brick wall in its attempt to rid itself of the need for a creator and designer.”
Climatologist Patrick Michaels has defended Spencer, arguing that his religious beliefs have nothing to do with his climate change research.
Dr. Michaels holds a “Ph.D. in ecological climatology from the University of Wisconsin-Madison” and is a senior fellow at the Cato Institute, a libertarian think tank whose agenda includes opposition to AGW. He is correct in arguing that Spencer’s religious beliefs have nothing to do with whether he is correct in his conclusions. Most likely, there are many researchers supporting AGW who are also deeply religious.
What bears on religion and science is the matter of demonstrable science as opposed to personal opinion. Spencer has published his research, some of it valid, some not so much. Base on his research and that of others he voices the opinion that AGW is without merit. It’s here the value of his opinion comes into play.
When a person says in one breath that AGW is invalid science, and in the next breath he expresses belief in a mythical person who created the universe in six days and has power over our daily lives, then you can begin to doubt his conclusions regarding AGW. My observation from many years is that if a person’s thinking is horribly screwed up in one part of his brain, it’s time to closely examine everything else he says.
The Age of Embarrassment is still upon us, and there will be more on this. Keep reading
