At it's weakest point however, there is a sad attempt to relate the ice core data to global warming. This could be parodied as "there is no evidence of recent dramatic global warming in the ice core data, therefore global warming exists." To be kinder, the author feels "since I know global warming exists from other sources, the lack of data supporting global warming in my ice cores means this must be an entirely new sort of warming." There clearly is an easier explanation.
The book, published in the fall of 2002, centers on the findings from the two-mile long ice core that Mayewski's team pulled from the center of the Greenland Ice Cap. This ice core, labeled GISP2, allowed scientists to track a wide range of climate variables in exquisite detail over the past 100,000 years. It produced many important findings that can help clarify the highly politicized climate controversy. The core reveals that Earth's climate is far from steady. Even without any contributions from manmade greenhouse gasses, ozone-depleting chemicals or particulates, regional and global conditions have swung from hot to cold and wet to dry many times, often with dramatic suddenness. Mayewski repeatedly makes the point that the climatologically calm, benign Holocene--the time period during which human civilization appeared and has developed--is a myth. The ten millennia or so since the end of the most recent ice age have been marked by two large global climate shifts, the Little Ice Age and the Medieval Warm Period, and many less drastic but still potent changes. He also presents intriguing evidence that some of these changes contributed to the downfall of several ancient civilizations, including the Mesopotamian Empire around 1200 BC, the Mayan Civilization around 900 AD, and the Norse colonies in Greenland around 1400 AD.
My only real criticism of the book is that it may present more of the nitty gritty history and findings of the GISP2 project than most readers want or need. Still, most of this is put into boxes which readers can dive into or skip as they choose.
While the research findings and their implications are fascinating, perhaps the most important contribution the authors make is their perspective. The data Mayewksi himself uncovered show that the climate is a complicated and sensitive system, pushed from regime to regime by a variety of natural forces. But Mayewski is equally clear that human activities, most notably the marked and well-documented increases in carbon dioxide and other greenhouse gasses, have joined the party, and must be considered in order to understand current conditions or predict future climate change. And he is clear that unless we take sensible steps to reduce our impacts on the system, we risk not just global warming and whatever changes that would bring, but increased climactic instability and unpredictability. To the authors' credit, they attempt to bring some calm into the climate debates by propounding ten realistic, commonsense principles. The reflect that, "No matter what we do, the climate will change." But they also admonish, "We should strive more for climate predictability than control," and "If we cannot have global control of climate policy, we must at least have global cooperation."
The Ice Chronicles is well worth reading, both for the hard-won scientific facts it presents and explains so clearly, and for the constructive, down-to-earth perspective it provides.

It had really no value as a buyers guide. Other books give you more on the history, and even breakdowns of which had which engines in regard to quantity.
Only good thing is it is not expensive.

It is premised upon a recent publication known as the "U.S. National Assessment" on global warming. The backchatter about this document is astounding; it has been well-documented that the climate models which serve as its base actually perform worse than random numbers when applied to the US in the last several decades.
Further, the climate models that were used in this Assessment aren't even representative of most other models. I have read that Assessment, now available from Cambridge Press. It considered many models, but chose two--which, respectively, predict the most extreme departures in temperature and rainfall over the US, compared to the many others considered. Not only are the models that serve as the basis for the Delcourt's book bad, they aren't even representative!
I offer this notion to prospective purchasers of this book: either the Delcourt's knew this, and didn't tell you, which makes them deceptive, or they did not, which makes them incompetent.
I work for a major government climate lab, and I can tell you that this book is a typical global warming joke. Unfortunately, the political climate is so bad that we can't talk about this much in public. Too bad, because the planet is really warming a bit. Would like to see a more honest book here, which admits to warming and to the limits of our science. My little research on this shows the bestselling title under global warming has the weird title "Satanic Gases", but looks much more interesting. Maybe that's why people are buying it and not this silly book by the Delcourt Bobos.
Thus, Paul and Hazel Delcourt, both paleo-ecologists teaching at the University of Tennessee, present the results of a massive three-year national study, The National Climate Assessment, by thousands of scientists to project the potential environmental changes in this country over the next hundred years. The authors then match the results of this massive work with a range of demographic studies that lead them to conclude that wide-ranging economic, political, and social change will result. Therefore, "Living Well In The Age Of Global Warming" provides the reader with a fascinating look at the range of possibilities that exist for one to "live well and prosper' in the radically changed ecological, social, and personal circumstances of a world undergoing radical and unavoidable change.
Indeed, while the serious reader may find fault with the authors' particulars in dealing with the range of alternatives available, one can hardly fault their central point, which is that the world will be radically changed both in terms of its climate and our potential cultural responses to those changes. Thus, whether discussing changing weather patterns (and the associated changes in storm tracks now predicted by many meteorologists) or exploring changes in temperature zones to the degree that millions may be forced to vacate areas like Georgia as they turn positively tropical, this is fascinating reading. They also discuss potential changes in forest cover, livable habitats, and many other related subjects. According to the authors, each of these factors will become increasingly important in determining the overall quality of life possibilities as global warming proceeds.
In essence, the authors have created an entertaining and informative book that openly discusses what the consequences of global warming may portend for each of us in practical and understandable terms, and in so doing they have rendered an important service to us all. While I admit that I did not like the "self-help to financial success" tone the prose sometimes degenerates into, I found myself so fascinated by other aspects of their careful thought that helped me to overcome any minor trepidation I had regarding the book. One can hardly argue with their central thesis; that the comfortable world we know is vanishing before our eyes, and that the shape of the one to come will be largely determined by the effects that global warming has on our society and our environment.
The book deals with a variety of different issue and a whole range of potential individual responses that the intelligent and savvy person can use to negotiate his or her way through the coming hardships. While I do not feel that this book is anything like the comprehensive "bible" activists need to carry on in the difficult days and years to come, it is certainly a provocative and thoughtful excursion into a subject matter few have dared to broach to date. Hopefully it provides us with just the opening salvo of what one prays will become both a national and international debate on what each of us needs to do to live more responsibally on the delicate skin of this, our living planet. I recommend it without hesitation; enjoy!
