This book provides a synthesis of the past decade of research into global changes that occurred in the earth system in the past. Focus is achieved by concentrating on those changes in the Earth's past environment that best inform our evaluation of current and future global changes and their consequences for human populations. The book stands as a ten year milestone in the operation of the Past Global Changes (PAGES) Project of the International Geosphere-Biosphere Programme (IGBP). It seeks to provide a quantitative understanding of the Earth s environment in the geologically recent past and to define the envelope of natural environmental variability against which anthropogenic impacts on the Earth System may be assessed. A set of color overhead transparencies based on the figures in the book is available free on the PAGES website (www.pages-igbp.org) for use in teaching and lecturing."

This book provides a unique, in-depth view of past, present and potential future climatic change in mountain regions, and in particular on the mechanisms which are responsible for this change. Other books which focus on environmental change in mountains focus more generally on the impacts of this change on mountain systems, rather than on the regional features of climatic change itself. The book enters into a high level of detail concerning results of international investigations which involve specialists from numerous climate-related disciplines. The book can be used in an academic and research context, for advanced graduate and doctoral students, as well as researchers working in various domains of relevance to climatic change issues. The book also has relevance in the context of future activities of the Intergovernmental Panel on Climate Change (IPCC), in terms of providing up-to-date knowledge of fundamental mechanisms and consequences of climatic change in mountain regions.

The Hadley and Walker Circulations are fundamental regulators of the Earth's energy budget. Although the Hadley Circulation is a well-known concept, surprisingly little attention has been paid to understanding both short and long-term variability of the system. This book reviews current knowledge of Hadley and Walker circulation dynamics and their interactions with the major global monsoon systems, and evaluates paleoclimatic records within the domain of the Hadley Circulation that shed light on past variability of climate over the last 1000 years, the Holocene (the last 11,500 years), glacial periods, and warm climate periods in the past. The book examines potentially important factors that may have affected the Hadley and Walker Circulations on these different time scales and evaluates changes in the Hadley Circulation and the monsoons as simulated by coupled models of past climate conditions, and predicted future conditions under an enhanced greenhouse effect. This book is meant to serve as a fundamental reference work for current and future researchers, graduate students in the atmospheric sciences and geosciences, and climate specialists involved in interdisciplinary research.

"Paleoclimatology: Reconstructing Climates of the Quaternary, Third Edition," provides a thorough overview of the methods of paleoclimatic reconstruction and of the historical changes in climate during the past three million years.

This thoroughly updated and revised edition systematically examines each type of proxy and elucidates the major attributes and the limitations of each. "Paleoclimatology, Third Edition" provides necessary context for those interested in understanding climate changes at present and how current trends in climate compare with changes that have occurred in the past. The text is richly illustrated and includes an extensive bibliography for further research.
A comprehensive overview of the methods of paleoclimate reconstruction, and the record of past changes in climate during the last 3 million yearsAddresses all the techniques used in paleoclimatic reconstruction from climate proxiesWith full-color throughout, and thoroughly revised chapters on dating methods, climate forcing, ice cores, marine sediments, pollen analysis, dendroclimatology, and historical recordsIncludes new chapters on speleothems, loess, and lake sedimentsMore than 1,000 new references and 190 new figures Essential reading for those interested in how present trends in climate compare with changes that have occurred in the past

Global warming is the number one environmental issue of our time, yet some prominent politicians have refused to accept scientific evidence of human responsibility and have opposed any legislation or international agreement that would limit greenhouse gas emissions. A few have gone even further and have tried to destroy the reputations of scientists researching climate change by deliberately undermining the credibility of their research. These politicians have sought to sow seeds of doubt in the minds of the public and to weaken public and political support for the control of fossil fuel use. In this powerful book, highly respected climate scientist Raymond Bradley provides the inside story from the front lines of the debate. In clear and direct language, he describes the tactics those in power have used to intimidate him and his colleagues part of a larger pattern of governmental suppression of scientific information, politics at the expense of empirically based discourse. Speaking from his experience, Bradley exposes the fault lines in the global warming debate, while providing a concise primer on climate change. The result is a cautionary tale of how politics and science can become fatally intertwined.
