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
The El Niño/Southern Oscillation (ENSO) phenomenon is a recurrent feature of the climate in tropical regions. In this volume leading experts summarize information gained over the past decade concerning diverse aspects of ENSO, which have led to marked improvements in our ability to forecast its development months or seasons in advance. This volume compares ENSO's modern morphology and variability with its recent historic and prehistoric behaviour. It expands and updates Diaz and Markgraf's earlier volume El Niño: Historical and Paleoclimatic Aspects of the Southern Oscillation (1992, Cambridge University Press). The volume will be of importance to a broad range of scientists in meteorology, oceanography, hydrology, geosciences, ecology, public health, emergency management response and mitigation, and decision-making. It will also be used as a supplementary textbook and reference source in graduate courses in environmental studies.

Book Description
The Physical Geography of South America, the eighth volume in the Oxford Regional Environments series, presents an enduring statement on the physical and biogeographic conditions of this remarkable continent and their relationships to human activity. It fills a void in recent environmental literature by assembling a team of specialists from within and beyond South America in order to provide an integrated, cross-disciplinary body of knowledge about this mostly tropical continent, together with its high mountains and temperate southern cone. The authors systematically cover the main components of the South American environment - tectonism, climate, glaciation, natural landscape changes, rivers, vegetation, animals, and soils. The book then presents more specific treatments of regions with special attributes from the tropical forests of the Amazon basin to the Atacama Desert and Patagonian steppe, and from the Atlantic, Caribbean, and Pacific coasts to the high Andes. Additionally, the continents environments are given a human face by evaluating the roles played by people over time, from pre-European and European colonial impacts to the effects of modern agriculture and urbanization, and from interactions with El Niño events to prognoses for the future environments of the continent.

Book Description
Comprehensive and up-to-date information on Earth’s most dominant year-to-year climate variation The El Niño Southern Oscillation (ENSO) in the Pacific Ocean has major worldwide social and economic consequences through its global scale effects on atmospheric and oceanic circulation, marine and terrestrial ecosystems, and other natural systems. Ongoing climate change is projected to significantly alter ENSO's dynamics and impacts. El Niño Southern Oscillation in a Changing Climate presents the latest theories, models, and observations, and explores the challenges of forecasting ENSO as the climate continues to change. Volume highlights include: Historical background on ENSO and its societal consequences Review of key El Niño (ENSO warm phase) and La Niña (ENSO cold phase) characteristics Mathematical description of the underlying physical processes that generate ENSO variations Conceptual framework for understanding ENSO changes on decadal and longer time scales, including the response to greenhouse gas forcing ENSO impacts on extreme ocean, weather, and climate events, including tropical cyclones, and how ENSO affects fisheries and the global carbon cycle Advances in modeling, paleo-reconstructions, and operational climate forecasting Future projections of ENSO and its impacts Factors influencing ENSO events, such as inter-basin climate interactions and volcanic eruptions The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the editors.

Book Description
The proposed book is not only a tribute to the work of Brückner (and indeed also a personal tribute, since Brückner wrote his book at the Institute of Geography of the University of Bern), but references to Brückner’s book are also a conceptual tool in the proposed book, though used sparingly and thoughtfully. Apart from providing historical context, references may facilitate introducing some complex topics, for instance by first presenting Brückner’s view and then complementing the picture with today’s understanding. References can be used for contrast: Comparing Brückner’s methods and data with today’s research concepts makes the progress in the field easily understandable. The enormous growth of information since Brükner’s time allows a much more detailed perspective on some scientific problems. Or references can be used to highlight similarity. Some aspects have not changed over time. Finally, the book complements Brückner’s studies by adding the arguably most interesting and certainly most relevant period, the past 120 years.

Book Description
With a complex assemblage of largely intact ecosystems that support the earth's greatest diversity of life, the Amazon basin is a focal point of international scientific interest. And, as development and colonization schemes transform the landscape in increasing measure, scientists from around the world are directing attention to questions of regional and global significance. Some of these qustions are: What are the fluxes of greenhouse gases across the atmospheric interface of ecosystems? How mush carbon is stored in the biomass and soils of the basin? How are elements from the land transferred to the basin's surface waters? What is the sum of elements transferred from land to ocean, and what is its marine "fate"? This book of original chapters by experts in chemical and biological oceanography, tropical agronomy and biology, and the atmospheric sciences will address these and other important questions, with the aim of synthesizing the current knowledge of biochemical processes operating within and between the various ecosystems in the Amazon basin.
