Climate Through the Ages: a Study of the Climatic Factors and Their Variations by C.E.P. Brooks – Second Revised Edition. NOTE: We have 75,000 books in our library, almost 10,000 different titles. Odds are we have other copies of this same title in varying conditions, some less expensive, some better condition. We might also have different editions as well (some paperback, some hardcover, oftentimes international editions). If you don’t see what you want, please contact us and ask. We’re happy to send you a summary of the differing conditions and prices we may have for the same title. DESCRIPTION: Softcover: 395 pages. Publisher: Dover Publications Inc.; (1970). Although it is a truism that the weather changes perpetually, we often forget that climate too can change appreciably. Approximately 20,000 years ago for example, much of North America was buried under an ice cap. About 8,000 years ago the Sahara Desert bloomed. And in the geological past, semitropical vegetation flourished close to the present Arctic circle. “Climate Through the Ages” is one of the few books that discusses the reasons for these changes, rather than simply listing them as items in historical geology. A modern classic in paleoclimatology, it has long been a standard work for geographers, meteorologists, anthropologists, geologists, historians, and for laymen interested in the general problem. Despite its scholarly stature, only a minimal acquaintance with the earth sciences is required to follow its clear exposition. To provide background for the reader who has not had previous training, Professor Brooks first discusses variable factors associated with climate. Atmospheric pressure and air circulation, circulation of the oceans, variation in solar radiation, astronomical factors in the orbit and position of the earth, absorption of radiation by the atmosphere, continental factors, precipitation cycles, mountain building, and similar topics. Among the important theories covered are those of Hobbs, Milankovitch, Bryan, Wegener, Huntington, Koppen, Kerner, Antevs, Spitaler, and Zeuner. The second part of the book is concerned with specific paleoclimates, particularly the Upper Carboniferous and the Quaternary, with special reference to continental drift. The third portion treats climactic change within the historical period, for most parts of the world. CONDITION: LIKE NEW. Book has clearly never been read, however it does show some handling/shelf wear (it is over 40 years old). There's a vertical crease on the back cover indicating that the cover had been over-flexed/bent at one time, but it is merely a crease mark, the cover was not bent over backwards. The spine heel was also bumped and there's a small 1/2 inch tear to the back cover. Last there's someone's name neatly handwritten in ink on the first blank page beneath the front cover. Otherwise the book is almost pristine, pages clean, crisp, unmarked (notwithstanding the one penned name described), unmutilated, tightly bound, unambiguously unread. Satisfaction unconditionally guaranteed. In stock, ready to ship. No disappointments, no excuses. PROMPT SHIPPING! HEAVILY PADDED, DAMAGE-FREE PACKAGING! #946a.

PUBLISHER REVIEW: The classic history of Earth's climate. This book mainly consists of an account of the variations of climate during geological times, and it deals especially with the Quaternary Ice-Age and the Post-Glacial period. Also discusses the climatic factors and their variation, geological climates and their causes, the climates of the historical past. PROFESSIONAL REVIEW: The material here is divided into three sections. In the first, various factors of climate are discussed with theories. In the second, the application of the principles laid down in the first section to the various problems presented by geological climates. The third section deals with the climates in different parts of the world during the historical period, or from about 5000 B.C. to present. Noteworthy to present day climatology is Brooks’ suggestions regarding the future of the arctic ice packs. He suggested that a slight change of conditions might set off a self-sustaining shift between climate states. Suppose, he said, some random decrease of snow cover in northern latitudes exposed dark ground. Then the ground would absorb more sunlight, which would warm the air, which would melt still more snow in a vicious feedback cycle. An abrupt and catastrophic rise of tens of degrees was conceivable, "perhaps in the course of a single season." Compelling and fascinating! READER REVIEW: C. E. P. Brooks believed that the ice pack was balanced on a knife edge -- that a rise of as little as 2 degrees Fahrenheit (1.1° C) in the temperature of the air might be sufficient to bring about its complete dissolution in summer, and that once melted away, it would not reform in winter until atmospheric temperatures fell again. In other words, the Arctic Ocean was bi-stable between two states, ice-covered and ice-free, and a slight shift in temperature would be enough to nudge it from one state to the other. Further, he believed that the Arctic was in fact ice-free during the hypsithermal -- from approximately 8,000 to 3,000 years ago. The is the classic and authoritative text in ancient climatology, a timeless masterpiece. I always ship books Media Mail in a padded mailer. This book is shipped FOR FREE via USPS INSURED media mail (“book rate”). The shipment will include free USPS Delivery Confirmation (you might be able to update the status of your shipment on-line at the USPS Web Site and free insurance coverage). If you are concerned about a little wear and tear to the book in transit, I would suggest a boxed shipment - it is an extra $1.00. Whether via padded mailer or box, we will give discounts for multiple purchases. International orders are welcome, but shipping costs are substantially higher. Most international orders cost an additional $12.99 to $33.99 for an insuredshipment in a heavily padded mailer, and typically includes some form of rudimentary tracking and/or delivery confirmation (though for some countries, this is only available at additional cost). There is also a discount program which can cut postage costs by 50% to 75% if you’re buying about half-a-dozen books or more (5 kilos+). Rates and available services vary a bit from country to country. You can email or message me for a shipping cost quote, but I assure you they are as reasonable as USPS rates allow, and if it turns out the rate is too high for your pocketbook, we will cancel the sale at your request. ADDITIONAL PURCHASES do receive a VERY LARGE discount, typically about $5 per book (for each additional book after the first) so as to reward you for the economies of combined shipping/insurance costs. Your purchase will ordinarily be shipped within 48 hours of payment. We package as well as anyone in the business, with lots of protective padding and containers. All of our shipments are sent via insured mail so as to comply with PayPal requirements. We do NOT recommend uninsured shipments, and expressly disclaim any responsibility for the loss of an uninsured shipment. Unfortunately the contents of parcels are easily “lost” or misdelivered by postal employees – even in the USA. That’s why all of our shipments include a USPS delivery confirmation tag; or are trackable or traceable, and are insured. We do offer U.S. Postal Service Priority Mail, Registered Mail, and Express Mail for both international and domestic shipments, as well United Parcel Service (UPS) and Federal Express (Fed-Ex). Please ask for a rate quotation. We will accept whatever payment method you are most comfortable with. If upon receipt of the item you are disappointed for any reason whatever, I offer a no questions asked return policy. Send it back, I will give you a complete refund of the purchase price (less our original shipping costs). . Most of the items I offer come from the collection of a family friend who was active in the field of Archaeology for over forty years. However many of the items also come from purchases I make in Eastern Europe, India, and from the Levant (Eastern Mediterranean/Near East) from various institutions and dealers. Though I have always had an interest in archaeology, my own academic background was in sociology and cultural anthropology. After my retirement however, I found myself drawn to archaeology as well. Aside from my own personal collection, I have made extensive and frequent additions of my own via purchases on Ebay (of course), as well as many purchases from both dealers and institutions throughout the world – but especially in the Near East and in Eastern Europe. I spend over half of my year out of the United States, and have spent much of my life either in India or Eastern Europe. In fact much of what we generate on Yahoo, Amazon and Ebay goes to support The Hermitage Museum in St. Petersburg, as well as some other worthy institutions in Europe connected with Anthropology and Archaeology. I acquire some small but interesting collections overseas from time-to-time, and have as well some duplicate items within my own collection which I occasionally decide to part with. Though I have a collection of ancient coins numbering in the tens of thousands, my primary interest is in ancient jewelry. My wife also is an active participant in the "business" of antique and ancient jewelry, and is from Russia. I would be happy to provide you with a certificate/guarantee of authenticity for any item you purchase from me. There is a $2 fee for mailing under separate cover. Whenever I am overseas I have made arrangements for purchases to be shipped out via domestic mail. If I am in the field, you may have to wait for a week or two for a COA to arrive via international air mail. But you can be sure your purchase will arrive properly packaged and promptly - even if I am absent. And when I am in a remote field location with merely a notebook computer, at times I am not able to access my email for a day or two, so be patient, I will always respond to every email.
