The Great Global Warming Blunder unveils new evidence from major scientific findings that explode the conventional wisdom on climate change and reshape the global warming debate as we know it. Roy W. Spencer, a former senior NASA climatologist, reveals how climate researchers have mistaken cause and effect when analyzing cloud behavior and have been duped by Mother Nature into believing the Earth’s climate system is far more sensitive to human activities and carbon dioxide than it really is.

In fact, Spencer presents astonishing new evidence that recent warming is not the fault of humans, but the result of chaotic, internal natural cycles that have been causing periods of warming and cooling for millennia. More carbon dioxide in the atmosphere is not necessarily to be feared; The Great Global Warming Blunder explains that burning of fossil fuels may actually be beneficial for life on Earth.

As group-think behavior and misguided global warming policy proposals threaten the lives of millions of the world’s poorest, most vulnerable citizens, The Great Global Warming Blunder is a scintillating exposé and much-needed call for debate.

Feedback Is The Critical Issue in Greenhouse Warming

Reviewed in the United States on October 4, 2015

Verified Purchase

This was a fascinating read for me. I am a PhD chemist who is no expert in climatology but I read as much as I can find on this topic. I know that the CO2 greenhouse effect is real. My interest is in the feedback loops in climate systems, since this determines the magnitude of the ultimate effects of greenhouse warming, and clouds are the major feedback factor. In all I have read previously the feedback from clouds was simply described as either: a) more clouds form as the atmosphere warms (negative feedback), or b) fewer clouds form as the atmosphere warms (positive feedback). A few months ago I wrote to a leading scientist on the IPCC with my questions about this. He returned a friendly email that said "Of the many feedbacks in the system, the cloud feedback has proved most vexing. As you pointed out in your message, we are not even confident that we know the sign of the feedback, globally". He also said in one of his lectures that cloud feedback is entered into the global circulation models as a single parameter, since these models do not estimate the cloud feedback. The uncertainty in the model predictions, just from this one parameter, is so large that the worst case greenhouse warming is obtained if strong positive feedback is input, and zero warming occurs if a strong negative feedback is input.

The Author's approach I found to be fully valid scientifically, and he is innovative in his approach. The science he does is exactly typical of the methods that I learned, and are the methods that have been used by scientists for hundreds of years. He is an expert in his field, and a leading expert in satellite monitoring of greenhouse warming. His concept that clouds have a dual function in greenhouse warming is insightful, and really opened my eyes to the concept of cloud formation as a chaotic process. His use of simple column models to explore the system is the same method as is favored by many climatologists. Prof. Spencer's concept of cloud feedback&forcing with a time delay between the forcing event and the climate effect cannot be modeled as a simple parameter. It is obvious to me that the 'overwhelming majority of climate scientists' don't bother to read, much less consider all information that is in the available literature. This is something that should raise concern among citizens.

To end my review here I have to recommend everyone read the Amazon 'one star' reviews of this book. One review recommends that people should read only the government websites to learn the 'science'. Others admit they didn't read the book, and would -never- read the book out of principal, yet feel fully qualified to review it. Most are just bitter and nasty without any substance. Hard to imagine how science can inspire ignorance like this. I suppose these are the same sort of people that persecuted Galileo for having an alternate viewpoint.

This book describes the current state of scientific knowledge about earth's climate.

Reviewed in the United States on May 17, 2019

Verified Purchase

I love it. For someone who was only interested in the weather forecast, this was a college level introduction to climate science. The author goes into great detail about how climate is determined. He points out where technology is lacking, so there are still important issues to be resolved. He points out where he believes the ICC view of climate is lacking. I was amazed about how complicated the forces are and how much contributes to temperatures. It is obvious that the science is not settled. However, since climate has been politicized by the Left, it is important to know their take on warming cannot be believed.

A Great Book That Could Have Been Greater

Reviewed in the United States on May 28, 2015

Verified Purchase

As someone who is doing his level best as a layman to get a firm grasp on the state of climate science, I found this book very engaging. However, if you're "brand new" to the topic, I wouldn't start here. Spencer explores in great detail a particular theory of his regarding clouds, one that has opened a promising line of inquiry, though it isn't likely to be the "last word" on the subject. On the other hand, his general approach to the topic of climate change is in line with other "giants" among the skeptics, such as Lindzen and Michaels, and his own contribution has been noted by his fellows. Spencer continues to study and publish on the issue of clouds and their relation to El Nino, La Nina, and Pacific Decadal Oscillation to this day.

While Spencer is generally careful not to mislead the reader in the body of the book, in the Summary & Conclusions section, he makes a lamentable mistake. Here is a quote that confused and disappointed me from that section:

"The first conclusion is that recent satellite measurements of the Earth reveal the climate system to be relatively insensitive to warming influences, such as humanity’s greenhouse gas emissions. This insensitivity is the result of more clouds forming in response to warming, thereby reflecting more sunlight back to outer space and reducing that warming."

The first sentence makes sense to me, and he defends it well in the book. The second sentence bothers me. Having gone back and re-read the part of the book where he lays out his cloud theory, I can now see that this statement would be misleading for a sloppy reader, and confusing to someone who follows his arguments carefully. Spencer didn't defend this statement in the body of the book. Rather, I thought that his argument was simply that a decrease in low cloud cover causes warming, and an increase in low cloud cover causes cooling, and also that clouds were acting as a "forcing" rather than a "feedback." The consensus view of clouds (based on models) has assumed that they act as a positive feedback, amplifying global warming. I thought he demonstrated logically that clouds almost certainly do not decrease as a result of warming (cloud feedback) but rather global warming is caused by decreasing clouds (cloud forcing). But nowhere in the book did he defend the notion that clouds increase "in response" to warming. In fact, Spencer has repeatedly affirmed (in public appearances) that the behavior of clouds remains mysterious. Perhaps the words "in response" were a "slip of the pen," albeit a significant one.

One other issue I had with this book was its failure to adequately defend (with data) the truth of the devastating impact of the green movement's energy and climate policies on the world's poor. I loved Spencer's passion here, but I wanted more facts.

While his conclusions about clouds are debatable, the important takeaway is this--the consensus view that says that the climate system is dominated by positive feedbacks (hence, the system is "unstable") is almost certainly wrong. Climate scientists need to explore natural internal variability in the climate system much more carefully.

Provocative and Challenging

Reviewed in the United States on February 18, 2017

Verified Purchase

My dad recommended this as part of the monthly book club he, my brother, and I do. His goal was to challenge our liberal leaning view of climate change while asserting something akin to "a bunch of this stuff about man-made climate change is government and individual driven misinformation"

Reading an argument against man made climate change - especially in the current political environment - is a good intellectual challenge. This book wasn't definitive or ultimately convincing, but it did offer up a cogent alternative hypothesis.

Simple science shows evidence that climate change could be due to natural causes.

Reviewed in the United Kingdom on June 14, 2019

Verified Purchase

Roy Spencer is a principal research scientist at the University of Alabama, a former senior climate scientist at NASA and now leads the team for the Advanced Microwave Scanning Radiometer for EOS on NASA’s Aqua satellite. He also co-developed the method of precisely monitoring global temperatures from satellites, and has provided congressional testimony on global warming - so he is very highly qualified to engage in the global warming debate.

This book describes his research, analysis and experiments to identify if climate change could have a natural cause in addition to any anthropogenic causes. His results lead to two conclusions brought about though climate researchers not separating cause and effect.

Firstly the climate is relatively insensitive to greenhouse gas emissions because clouds form in response to warming, thereby reflecting more sunlight back to space and reducing the warming. This is called negative feedback, which the IPCC acknowledge but refuse to include in the output from their climate models. Instead the IPCC erroneously predict a strongly positive feedback resulting in high sensitivity causing increased warming or even catastrophic climate change.

Secondly, Spencer details new satellite evidence showing that the global warming observed over the last 100 years may be due to the Pacific Decadal Oscillation causing natural cloud changes – direct evidence that the Earth is capable of causing its own climate change through chaos in the climate system. Spencer demonstrates how the IPCC refuses to even consider the possibility that most global warming might be caused by natural events because it has the preconceived agenda of anthropogenic causes.

This book is simple science, and very easy for any layman to understand. It should be compulsory reading for everyone – especially school children striking over climate change. Every school library should have copies of this book!

The Biggest Deception in History

Reviewed in Canada on April 16, 2017

Verified Purchase

A very good explanation on his theory of warming. A bit above my knowledge base but well written and presented so I was able to follow most of what he is saying. Spencer proposes that clouds have an influence on the feedback side of the equation which the IPCC has ignored in their extremist push on forcings. He tries to simplify his explanations so an ordinary person like myself can understand that there are other natural factors that may be influencing the warming that we have experienced in the past. He points out the down side of the man made global warming scam (supposedly CO2 induced) and describes how the scientific method has been replaced by political and financial agendas. Books like his and those of Tim ball do not generate news headlines unless someone is killed or a major catastrophe happens due to actual proven man made global warming (and that has yet to happen). It is really quite sad that most people are so busy with their day to day lives that they will not make the effort to educate themselves on this most important subject that over time will affect us all financially in a bad way due to wrongly imposed taxes, especially in Canada. As most true unbiased scientific books (non IPCC/UN backed publications) point out, man made global warming is perhaps the biggest deception brought about by mankind... on mankind.

There is no Climate Change Crisis

Reviewed in Canada on January 19, 2021

Verified Purchase

I used this product to learn more about climate change science. I came away with the impression that the science certainly is not settled. There needs to be a lot more study on the subject of nature processes and cycles in our climate. The fact is no one knows how much if any of the modest warming observed in our climate during the past 100 years is due to carbon dioxide and how much is due to natural influences. Clearly that question of what actually drives climate change needs to be answered before we go on tearing down our fossil fuel powered civilization.

The general public needs to be informed of this side of the question too. It has some valid points to be made that would make for a more complete discussion and more effective decision.
