Climate Science: Unsettled Questions, Uncertain Answers, and Their Impact on Our World

Tecumseh: Reads easily. It debunks many statistics presented in mainstream meadia by showing how data was mamipulated, trunkated and collated in order to convey a political agenda.
Very clear and well presented explanations. It increased my knowledge of climate and weather changes. Fully recommend it.

BMK: I read the hardcopy edition. Highly recommend. Here you get information on what is true on climate change including the effect of man. And what is not. And how badly the truth gets distorted by others, including people who should know better (and journalism that just wants shock and awe headlines). Whatever your opinions, I don't think you have any business talking about climate change until you have read this book.

The key prescription I got: we need to think a lot more about adaptation to the inevitable and redirect resources away from some of the prevention efforts.

I hope the author does a second edition when enough time has passed to warrant it. Surely the misinformation that will likely continue will need an update in a few years. And the author surely will have more people who went after him with illogic and untruth that he can write more about.

By the way, I deal with science misconceptions all the time in my job, like the idea that people feel temperature (we don't, and if it shocks you try "Misconceptions About Temperature" on YouTube). So it is from that viewpoint that is part of the reason I like how the author of this book deals with the...

J. Tarrant: Although Steven Koonin's book concentrates on climate change, its key message is tucked away in one of the final chapters and provdes the title for my review. Koonin suggests that matters of climate change are inherently uncertain and that's the way it should be. He separates weather from climate and I would add that given how bad we are at forecasting the weather as litle as a week in advance, it seems crazy to think that the outcomes of our models of climate change are beyond discussion. I found the book extremely thought provoking and, whilst I certainly don't agree with everything in it, I will be putting the book back on my shelves for future reference. My one gripe is that many of the graphs are REALLY hard to read as they are reproduced in monochrome but must surely have been colour originals. Any second edition should address this weakness as I'm sure the book would be a much easier read if the illustrations were more accessible. Balancing that shortcoming, there is a huge list of references and most of the links I tried are still live, which adds considerably to the value of this book.

Charlie Peters: “Unsettled? What Climate Science Tells Us, What It Doesn’t, and Why It Matters,” by Steven Koonin. Dr. Koonin (Ph.D.) is very qualified to write such a book as this. He Served as Undersecretary for Science in the U.S. Dept. of Energy (Obama Administration), and he has written more than 200 peer-reviewed papers in the fields of physics and astrophysics, and many, many more entries on his resume.

Let me first mention that “Unsettled?” is a page turner. I am not a fast reader, but I am a persistent reader. It took me two days to read it, because I didn’t read for speed but I read for understanding. He had me captivated, right from the beginning. I started reading his book and turned the television and radio off, for two days. Reading his book was better than watching a movie.

His book is about Climate Change and it about what we should have been told all along. He could have written it in highly technical language, but he didn’t. It is easy to understand and he makes his point quite clear. Every point he makes in his book he has references to back up what he writes. He put the science back into ‘Climate Change.’ He condemns those that use such...

DT Flynn: If you want fact and evidence-based on why the disruptive climate policies are effectively lowering worldwide quality of life, this is an easy to digest and logical resource that uses the IPCC data to examine the "catastrophic crisis" propaganda with reason, logic, and an ethical and sane world-view. A must read if you care for humanity and don't want future (or current) humanity to be unjustly thrust back into pre-industrial quality of life.

Poppa: I would suggest to get hardcopy and follow along with the audiobook and highlighter as it is complex and full of hard to dispute factual data that you may need to hear multiple times to understand.
Really shows how anyone can control a narrative by lying with statistics.
Data omission seems to be the main source in creating a narrative.
They really do look to be working backwards adjusting and omitting data until it supports a defined conclusion.
The also lie about the author by saying he is a "denier". He stats multiple times with data that man's use of fossil fuels has aided in co2 level increase but presents hard data, omitted data, that co2 is not the main cause of climate change but is a byproduct of cyclical climate change over earths history.
Makes you question everything you are ever told about everything.
It seems they jumped the shark this time and it will be very hard to continue to control the climate change narrative.

RamonRamon: El autor fue parte del gabinete de Obama, desempeño el papel de subsecretario de energía. Analizo el calentamiento global y en este libro desarrolla su idea de que NO HAY PRUEBAS EXACTAS DE QUE LOS HUMANOS ESTAMOS CAUSANDO EL CALENTAMIENTO GLOBAL, de ahí el nombre "unsettled". Comenta que los contaminantes que generamos los humanos afectan al ambiente pero de una forma muy muy diminuta. Mediante decenas de gráficas y estadísticas demuestra su argumento.

Sin duda un libro que abre los ojos en cuanto este tema. Muy recomendado!

Michael Murray: Unsettled – Book Review by Michael J. Murray
A Master Teacher Explains Climate Science
A while ago, I read a WSJ Op Ed article Steven Koonin about our changing climate. The clarity of his prose, the objective tone, and the forthrightness of his convictions impressed me. Dr. Koonin, after having attended recent international conferences on climate change, expressed concern that many of the participants lacked a deep understanding of their subject. They were regarding as “settled” certain climate projections that still needed to undergo the rigorous checks and balances of the scientific method. Only a scientist of substantial intellectual clout would venture such a bold statement.
Koonin’s credentials as a climatologist are impeccable – BS in physics from Cal Tech, PhD in theoretical physics from MIT, award-winning classroom teacher, five years as chief scientist for British Petroleum, researching renewable energy options, Undersecretary for Science in the Department of Energy under President Obama. This experience in the three spheres that most influence climate science – the scientific, the business, and the political - affords him a unique perspective from...
