Book Description
Integrating issues of climate modelling, ecological and human dimensions of climate change, and policy implications, this volume addresses the critical problems of climate change from a Southern Hemisphere perspective. However, the spatial focus in the book is not defined just by latitude, but also by geopolitical criteria: encompassing the developing world, the tropics north of the equator, as well as regions south of the equator. The book begins by examining the geographic and geopolitical plurality of the Earth, including north and south distinctions and the science/policy plurality. A hemispheric perspective on coupled climate modelling is then discussed, providing a state-of-the-art summary of climate modelling as it pertains to the Southern Hemisphere. In addition, the book examines the interaction of humanity, the biosphere and the atmosphere, discussing the biospheric effects of climate change, possible climatic impacts of biospheric change, particularly tropical deforestation and the human health implications of climate and climate change.

Book Description
South America is a unique place where a number of past climate archives are ava- able from tropical to high latitude regions. It thus offers a unique opportunity to explore past climate variability along a latitudinal transect from the Equator to Polar regions and to study climate teleconnections. Most climate records from tropical and subtropical South America for the past 20,000 years have been interpreted as local responses to shift in the mean position and intensity of the InterTropical Conv- gence Zone due to tropical and extratropical forcings or to changes in the South American Summer Monsoon. Further South, the role of the Southern Hemisphere westerly winds on global climate has been highly investigated with both paleodata and coupled climate models. However the regional response over South America during the last 20,000 years is much more variable from place to place than pre- ously thought. The factors that govern the spatial patterns of variability on millennial scale resolution are still to be understood. The question of past natural rates and ranges of climate conditions over South America is therefore of special relevance in this context since today millions of people live under climates where any changes in monsoon rainfall can lead to catastrophic consequences.

Book Description
Sensational images and stories about variations in Earth's climate and their impacts on society are pervasive in the media. The scientific basis for these stories is often not understood by the general public, nor even by those with a scientific background in fields other than climate science. This book is a comprehensive resource that will enable the reader to understand and appreciate the significance of the flood of climate information. It is an excellent non-mathematical resource for learning the fundamentals of climate analysis, as well as a reference for non-climate experts that need to use climate information and data. The focus is on the basics of the climate system, how climate is observed and how the observations are transformed into datasets useful for monitoring the climate. Each chapter contains Discussion Questions. This is an invaluable textbook on climate analysis for advanced students, and a reference textbook for researchers and practitioners.

Book Description
This book fills a significant gap in the climatological literature, providing a comprehensive assessment of the climates of the southern hemisphere. It is the first book of its type to provide a consolidated view of the climates of southern Africa, Australia, South America and Antarctica, addressing past and future climates as well as those of the present. Present climates are considered in the first part of the book, to provide a background against which past and future climates can be investigated. Emphasis in the book is on the inter-relatedness of global, synoptic and smaller scale aspects of southern hemisphere continental climates. Discussion of topical, but fundamental, concerns including El Niño, global warming and climate variability is incorporated throughout the text. The study of the climatology of the southern hemisphere is fundamental to our understanding of climates and climatic issues across the globe. The book will therefore be of particular interest to scientists interested in climate with a focus beyond the southern hemisphere, as well as those with a specialised interest in all or part of the southern hemisphere. It is also a significant addition to the literature for climate researchers as well as for undergraduate students studying climatology in the atmospheric, environmental and earth sciences.

Book Description
This is the first book to provide a comprehensive overview of climate change–related investigations carried out by Indian researchers through initiatives in southern high latitude regions. It explains climate variability over the Southern Ocean and Antarctica; air, sea, ice, and atmosphere interactions; and the impact of climate variability on sea ice and the polar atmosphere. The data were gathered at two Indian research bases, Maitri and Bharti, which are ideal sites to study and understand climatic evolution in Antarctic in the past and recent changes. This book helps to understand climatological perspectives and to evaluate some of the most pressing issues in the south polar region. FEATURES Highlights the achievements of India in the contemporary field of Antarctic climatology Presents four decades of research by Indian scientists in Antarctica, which is now shared for the first time with the global community Includes case studies on climatological and environmental conditions of natural archives to shed light on climate scenarios in the Southern Ocean and Antarctic regions Covers various aspects of climate variability and induced air-sea-ice-atmosphere interactions This book is edited by one of the top scientists and researchers of India in the field of paleoclimatology, and the contributors are experts in the Antarctic region.

Book Description
Climate models show that climate change is not a uniform process. Areas of increased temperature are situated near areas of decreased temperature, areas with increased precipitation adjoin areas of drought. This is one of the reasons why climate change is so difficult to detect. Any parameter must be considered and tested locally or regionally and not on an average globally. This book gives an overview of current research methods and results in the different fields of climate research including modelling. In addition, it contains a hemisphere-wide stratigraphic data base with about 80000 species. All paleoclimatic data as well as a state-of-the-art atmospheric circulation model in a PC version are included. So both research and graduate teaching are supported with high-end software running on affordable computers, also in those countries that have no access to Cray super computers. Thus, this book will be of interest to all researchers and scientists in the field of climatology.

Book Description
Glaciers in the Andes are particularly important natural archives of present and past climatic and environmental changes, in significant part because of the N-S trend of this topographic barrier and its influence on the atmospheric circulation of the southern hemisphere. Strong gradients in the seasonality and amount of precipitation exist between the equator and 30° S. Large differences in amount east and west of the Andean divide also occur, as well as a change from tropical summer precipitation (additionally modified by the seasonal shift of the circulation belts) to winter precipitation in the west wind belt (e. g. , Yuille, 1999; Garraud and Aceituno, 2001). The so-called 'dry axis' lies between the tropical and extra tropical precipitation regimes (Figure 1). The high mountain desert within this axis responds most sensitively to the smallest changes in effective moisture. An important hydro-meteorological feature on a seasonal to inter-annual time-scale is the occurrence of EN SO events, which strongly control the mass balance of glaciers in this area (e. g. , Wagnon et ai. , 2001; Francou et ai. , in press). The precipitation pattern is an important factor for the interpretation of climatic and environmental records extracted from ice cores, because much of this information is related to conditions at the actual time of precipitation, and this is especially so for stable isotope records. Several ice cores have recently been drilled to bedrock in this area. From Huascanin (Thompson et ai. , 1995), Sajama (Thompson et ai.
