Bravo to you both. I got the book for Christmas and finished reading it a couple of days ago. I thought it was very well written and your argument is, of course, correct. I know of quite a few people, in oceanography anyway, who share your view on the models (myself included). Where I stand, you have done a great job and you are to be commended.

I am late in telling you both how much I have enjoyed reading your excellent book "Taken By Storm." I learned many things from your book. Congratulations on going to so much effort at producing this important volume. I loved your humor and unique insights. Your book is (and will) make a very important contribution at trying to hold back the crazy and irrational global warming tide.

I am nearly finished reading Taken by Storm and have thoroughly enjoyed it. I also learned a lot. I have degrees in math and meteorology and have been active in the profession for over 30 years, but many of your concepts and descriptions treated this "old field" in a new and refreshing way. In particular, your descriptions of the meaninglessness of "average temperatures" were superb! Thank you again for your service to climate science.

The monograph by Christopher Essex and Ross McKitrick occupies a very important place among “non-orthodox” publications...Christopher Essex and Ross McKitrick have written the most timely (preparations of the IPCC Report-2005 have already started) and very important book...there are many ideas and concrete information in the book which may be useful to start at last productive scientific discussions in those basic scientific journals which did not allow “dissidents” to speak before.

Essex and McKitrick have written a good natured but ultimately serious, well documented, and scientifically careful analysis of how a crisis defying both common sense and normative science engulfed the popular imagination, the body politic, and much of the scientific community. One hopes the message of Taken By Storm can be absorbed before that damage, not due to global warming but rather to the surrounding hysteria, becomes even more painful and wasteful.

Taken By Storm is an excellent book. I have been looking for something like it for a couple of years. A well-written and easy to read book, on a subject where science has been absent for a long time. I specially like chapter 3. "Climate Theory Versus Models and Metaphors." It should as soon as possible be introduced to European readers... The book can be read by all kinds of people. You can learn about the difference between Science and "Official Science". You can learn about the "Greenhouse metaphor". And much, much more! People working with education policy and teachers educating young people should certainly read this book. As said on page 23: "Many sophisticated and influential people today have a level of scientific and mathematical knowledge that would not compare to that of a monk from the Middle Ages" With long experience of science and advanced engineering in industry and at University, I say, Buy the book, and very important, start discussing!

I have just finished reading Taken by Storm and want to commend you for the superlative job you did, especially in your use of metaphors to explain the complexities of the math.  I considered myself well informed prior to reading your book but I was surprised at how much I was unaware of -- I can only guess at the level of frustration you both must feel to have the clarity of insight conveyed by your book and yet to be faced daily with the barrage of media merrily piping us down an entirely different path.

While many professors of Climate Science realize that carbon dioxide generated by human activity has caused little or no global warming, Essex and McKitrick, as outsiders to the field, provide the most entertaining exposé of climate modeling nonsense I have seen. The flaws in climate modeling, the absence of water vapor as the most important greenhouse gas in most enviro manifestoes, the fraud behind the "hockey stick" graph of temperature over the last 1,000 years, and the lack of coverage of the remaining ground temperature measurement stations are all revealed, and backed with citations to peer-reviewed journals. Even the dynamics of human group polarization are explained at length as the reason why this subject receives almost no serious scientific discussion.

I recently purchased your book "Taken by Storm" and I want to tell you that I enjoyed it tremendously. It is a very clever piece of work! I have read a lot about the climate problems in the last few years, but this is the best text I have yet seen. I am a retired chemical engineer with special interest in "transport phenomena", which is also the underlying science in climate studies. What I liked best about your book was that it showed at the same time: good science, common sense, good logical analysis, a broad view of the world, a practical approach, and last but not least: a sense of humour. I wish you very much success with the sales of your book. Of course I sincerely hope that some politicians will read it, but I know it is not likely.

We have no proven theory of global warning, we have models which we have run with scenarios and they can be made to predict almost anything and in any case warming may not be a bad thing. Take the trillions Kyoto would cost to implement and spend a little bit on improving the physics but spend most of it on feeding, clothing and educating the hungry in deprived societies. Affluent societies can handle change. That is proven.
Overall I didn’t like this book; I don’t like its quirky style and smirky cleverness. It is, however, a very good book, a rollicking good read and, if not quite ‘vital’ then certainly an intelligent and worthy political statement from a mathematician and an economist based upon both the art and the science of their subjects.

The discussion is extensive and sometimes incisive: readers are introduced to the problems of sub-grid-scale parameterization, the dangers of turbulence and chaotic behaviour, the pitfalls of truncation errors, the perils of averaging, the difficulty of attributing changes to anthropogenic causes, and other issues well known to climate modelers and certainly of interest to anyone who would deepen their understanding of climate... While I am not convinced by their arguments and disagree with their conclusions, I believe that they should be listened to. The authors are a pair of earnest and perhaps somewhat idealistic academics who have made a valiant effort to bring their honest objections to a broad public...Science advisors and policy makers would do well to read "Taken By Storm"

Paul LeBlond, PhD

I have greatly enjoyed reading it, although some of the analogies and approaches used in the text are somewhat far-fetched…I agree that temperature per se is not a valid value to describe the state of our Earth. As you write, adding up temperatures and then dividing them with the number of data to give an average (mean) is nonsense.
Looking at any station values over the past century will show variations and in most cases there will be a rise from 1900 to the 30s and then a gentle drop to the 50-60s to rise again. I can not see that these annual/monthly/daily averages would be nonsense. What is nonsense is to assume that averaging the trends from the few thousand records available will give a reliable global average.
As a marine scientist, I am very much aware of the difficulty in measuring Sea Surface Temperature or even more difficult, sea surface air Temperature and therefore the centennial rise 0.6 C by IPCC can not be taken at face value. Anyhow, a global warming is probable, but I agree that the connection between GHG and T is far from proven. Your discussion on past CO2 is right down to the point. CO2 in ice is a controversial issue.
Best regards and thanks for a timely book

I read "Taken by Storm" by Chris Essex and Ross McKitrick in a single sitting one recent Saturday. I feel lucky to have found these two clear voices from your great country--
Canada. The book conveys a sense of calm (despite the action-packed narrative) and inspiration (knowing that there are still a few caring and honorable scientists out there) --- since Chris and Ross have the exceptional ability and courage to clarify the physics of proposed "global warming" by atmospheric CO2 without all the usual watered-down explanations. Yet they really are able to tell it with such great humor, unique insights and helpful summary of where we are in the actual scientific understanding of the key questions to date.
So, I strongly recommend this book in case you have not had a chance to read yet.
Chris and Ross are two solid contacts to put on your speed dial when it comes to the sorry politics behind the confusing non-scientific assumptions and claims regarding carbon dioxide and a supposedly disastrous warming world, too often blamed by simplistic thinkers on the hopeless greed of big-bad fossil-fuel industries and CEOs.

Global warming can be happening without any extra carbon dioxide in the air, simply because of natural variability. Yet it is the widespread belief that the two are related (funny enough without a sound scientific proof!). There are of course some physical mechanisms that will relate increased concentrations in carbon dioxide and warmer surface temperatures, but climate is (as the authors clearly explain) very complicated thing. In this book Essex and McKitrick very methodically review the problems associated with such a relation. They elaborate on the actual physical meaning of temperature, on the problems of constructing the so-called global temperature records, on the assumption that more carbon dioxide in the air necessarily means higher surface temperatures, and on the issue of detecting a climate change and attaching an uncertainty to it (chapters 3-7). The rest of the chapters are discussions about the underlying politics and scientific administration and how, in the authors' opinion, they are handling the global warming issue. Their arguments are scientifically sound and they make some good points. Both authors are accomplished scientists...all the arguments made about the meaning of temperature and averages are correct. As we always say, however, "given two scientists there are three opinions". So, Essex and McKitrick will face up to some arguments. I am sure (judging from their writing style) that they will not mind that. I think that this is the great contribution of this book. It offers a different view that is against the mainstream. There is nothing wrong with this. Lets open up a debate and lets see who is willing to participate.

For anyone interested in the science and economics of global climate change, and what we must be done to prevent it from happening, Taken by Storm is required reading. Any politician who has failed to read this book and yet is willing to commit society's resources to avert global warming, while knowing that millions of children die each year because they lack access to clean water, has been derelict in his or her duty to the public. In this book, Professors Essex and McKitrick present a powerful case against the mainstream view that currently holds sway in policy circles - that global warming is upon us, that its consequences will be nothing short of a global disaster, and that the poor will be the most devastated by it. They point out that, while much good climate and economic science has taken place over the past several decades, the science of global warming is still in its infancy - many difficult problems remain to be researched. However, the science that is currently available has been interpreted by the media, environmentalists, science bureaucracies and even some practicing scientists in a way that hides the depth of uncertainty and exaggerates the perceived risks. The environmentalists finally have an issue that can be used to slow or even halt economic growth and its supposed harmful effects, while the scientist has an issue that can be used to pry open the public purse for research on a grand scale. All sides are simply responding to economic incentives and are caught up in a game they can't break free from. Unfortunately, as these authors demonstrate, science itself may be the long-run loser.

Christopher Essex and Ross McKitrick cut through all the obfuscation and double speak which surrounds the Kyoto Accord, one of the most complex scientific and economic issues of our times. This book should be required reading by policy makers, and any one in the general public who is concerned about what the Kyoto Accord really means for the environment and the economy.

“Taken by Storm” is a book that should be required reading by anyone who wishes to either discuss or develop policy concerning global warming, including the media and especially politicians. The two authors are eminently qualified to deal in this topic...“Taken By Storm” is one of the most comprehensive and readable publications on the topic of global warming that is currently available.
