Book Synopsis Past Climate Variability in South America and Surrounding Regions by : Francoise Vimeux
Download or read book Past Climate Variability in South America and Surrounding Regions written by Francoise Vimeux and published by Springer Science & Business Media. This book was released on 2009-08-04 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Climate Variability and Change in High Elevation Regions: Past, Present & Future by : Henry F. Diaz

This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Historical Climate Variability and Impacts in North America by : Lesley-Ann Dupigny-Giroux
Download or read book Historical Climate Variability and Impacts in North America written by Lesley-Ann Dupigny-Giroux and published by Springer Science & Business Media. This book was released on 2009-09-18 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climatologists with an eye on the past have any number of sources for their work, from personal diaries to weather station reports. Piecing together the trajectory of a weather event can thus be a painstaking process taking years and involving real detective work. Missing pieces of a climate puzzle can come from very far afield, often in unlikely places. In this book, a series of case studies examine specific regions across North America, using instrumental and documentary data from the 17th to the 19th centuries. Extreme weather events such as the Sitka hurricane of 1880 are recounted in detail, while the chapters also cover more widespread phenomena such as the collapse of the Low Country rice culture. The book also looks at the role of weather station histories in complementing the instrumental record, and sets out the methods that involve early instrumental and documentary climate data. Finally, the book’s focus on North America reflects the fact that the historical climate community there has only grown relatively recently. Up to now, most such studies have focused on Europe and Asia. The four sections begin with regional case studies, and move on to reconstruct extreme events and parameters. This is followed by the role of station history and, lastly, methodologies and other analyses. The editors’ aim has been to produce a volume that would be instrumental in molding the next generation of historical climatologists. They designed this book for use by general researchers as well as in upper-level undergraduate or graduate level courses.
Book Synopsis Climatic and Ecological Change in the Americas by : James Andrew Whitaker
Download or read book Climatic and Ecological Change in the Americas written by James Andrew Whitaker and published by Taylor & Francis. This book was released on 2023-08-17 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comparative analysis of the experiences, responses, and adaptations of people to climate variability and environmental change across the Americas. It foregrounds historical ecology as a structural framework for understanding the climate change crisis throughout the region and throughout time. In recent years, Indigenous and local populations in particular have experienced climate change effects such as altered weather patterns, seasonal irregularities, flooding and drought, and difficulties relating to subsistence practices. Understanding and dealing with these challenges has drawn on peoples’ longstanding experience with climate variability and in some cases includes models of mitigation and responses that are millennia old. With contributions from specialists across the Americas, this volume will be of interest to scholars from fields including anthropology, archaeology, geography, environmental studies, and Indigenous studies.
Book Synopsis Indigenous Peoples and Climate Change in Latin America and the Caribbean by : Jakob Kronik
Download or read book Indigenous Peoples and Climate Change in Latin America and the Caribbean written by Jakob Kronik and published by World Bank Publications. This book was released on 2010-06-25 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the social implications of climate change and climatic variability on indigenous peoples and communities living in the highlands, lowlands, and coastal areas of Latin America and the Caribbean. Across the region, indigenous people already perceive and experience negative effects of climate change and variability. Many indigenous communities find it difficult to adapt in a culturally sustainable manner. In fact, indigenous peoples often blame themselves for the changes they observe in nature, despite their limited emission of green house gasses. Not only is the viability of their livelihoods threatened, resulting in food insecurity and poor health, but also their cultural integrity is being challenged, eroding the confidence in solutions provided by traditional institutions and authorities. The book is based on field research among indigenous communities in three major eco-geographical regions: the Amazon; the Andes and Sub-Andes; and the Caribbean and Mesoamerica. It finds major inter-regional differences in the impacts observed between areas prone to rapid- and slow-onset natural hazards. In Mesoamerican and the Caribbean, increasingly severe storms and hurricanes damage infrastructure and property, and even cause loss of land, reducing access to livelihood resources. In the Columbian Amazon, changes in precipitation and seasonality have direct immediate effects on livelihoods and health, as crops often fail and the reproduction of fish stock is threatened by changes in the river ebb and flow. In the Andean region, water scarcity for crops and livestock, erosion of ecosystems and changes in biodiversity threatens food security, both within indigenous villages and among populations who depend on indigenous agriculture, causing widespread migration to already crowded urban areas. The study aims to increase understanding on the complexity of how indigenous communities are impacted by climate change and the options for improving their resilience and adaptability to these phenomena. The goal is to improve indigenous peoples rights and opportunities in climate change adaptation, and guide efforts to design effective and sustainable adaptation initiatives.

Book Synopsis Influence of the Sea Surface Temperature Decadal Variability on Tropical Precipitation: West African and South American Monsoon by : Julián Villamayor
Download or read book Influence of the Sea Surface Temperature Decadal Variability on Tropical Precipitation: West African and South American Monsoon written by Julián Villamayor and published by Springer. This book was released on 2019-07-05 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the Sea Surface Temperature (SST) patterns of decadal-to-multidecadal variability observed and simulated by 17 general circulation models (GCMs) are analyzed. Furthermore, their impact on precipitation in West Africa and South America and the atmospheric mechanisms involved are assessed. Through this analysis, the effect of external forcings on these impacts and the relative contribution of decadal-to-multidecadal variability patterns of SST to precipitation are presented in depth. Finally, a humid period in the West African region of the Sahel during the 19th century, previously little documented, is analyzed using an atmospheric GCM. The monsoons of West Africa and South America have shown changes in the timescales of a few decades. Previous work suggests a relationship with patterns of decadal-to-multidecadal variability of SST, such as global warming and the Atlantic and Pacific variability. However, the dynamics underlying this relationship and its simulation by current GCMs had not been addressed in a consistent manner. This is the main motivation of this book. The results of this book not only represent a great step forward in our understanding of the changes in the precipitation regimes of the studied regions, but they can also be of great help for the improvement of decadal prediction systems and the associated social consequences.
Book Synopsis Wet and Dry Periods in Regions Surrounding the Atlantic Ocean Basin by : Anita Drumond
Download or read book Wet and Dry Periods in Regions Surrounding the Atlantic Ocean Basin written by Anita Drumond and published by Frontiers Media SA. This book was released on 2016-05-20 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic Ocean is the second-largest of the world's oceanic divisions. It is bounded by the continents of America, Europe and Africa and at its pole wards margins by the Arctic and the Southern Oceans. Different climatic patterns can be observed along its large latitudinal domain, which extends from the equator to sub-polar regions. Thus, different tropical and extra-tropical meteorological systems may have some influence on the characterization of precipitation regimes observed surrounding the basin, such as the Intertropical Convergence Zone (ITCZ), tropical monsoon systems, westerly storm tracks and atmospheric rivers. The subtropical regions of the Azores and South Atlantic high pressure systems are large evaporative areas which act as important moisture sources for the adjacent continents. Variations in the oceanic characteristics may influence the moisture transport towards the neighboring landmasses and alter the precipitation. The influence of climatic variability modes manifest not only over the Atlantic Ocean, but also over other oceanic regions, may also interact with the regional hydrological budget, thereby generating long periods of drought or excessive precipitation over the Atlantic rim landmasses. This Research Topic intends to highlight the advances of the scientific community in investigating the continental precipitation surrounding the Atlantic Ocean and its variability on various temporal and spatial scales.

Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests affect climate, and the removal of the forests will change climate. Or not? This book discusses basic questions on how far, if at all, tropical deforestation leads to climatic change. The question of this uncertainty is particularly addressed. One important consequence of the uncertainties of whether deforestation affects climate is how scientific findings best illuminate the policy-making process.

This book was released on 2013-07-11 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of ten years’ of scientific research carried out by the authors on Isla de los Estados. The research includes their doctoral thesis and many published scientific papers related to the island. The book is divided into two principal parts. The first part covers different social and natural aspects of this remote island and includes chapters on the scientific and historical background, physiography with topographical and hydrographical descriptions, climate and oceanographic circulation, vegetation and geology (including stratigraphy, structural geology and geological history). The second part comprises a reconstruction of the paleoenvironmental, paleoclimatic and paleogeographic history of the island from the Last Glacial Maximum to the present, correlating with other paleoecological records from the southern part of Isla Grande de Tierra del Fuego and Patagonia. This second part also includes a geomorphological chapter with a characterization of the principal erosive glacial landforms on Isla de los Estados constructed by means of morphometric analysis, inventories, maps, paleogeographic and glacial models, and a paleoecological chapter evaluating the palaeoenvironment and palaeoclimatic conditions that prevailed during the Late Pleistocene-Holocene times based on pollen and diatom analysis from three 14C-dated peat bogs and lakes. Finally, the book concludes with a review of the island’s archaeology and the relationship between the palaeoenvironmental history and human occupation of this island.

Book Synopsis Climate Variability, Climate Change and Social Vulnerability in the Semi-arid Tropics by : Jesse C. Ribot
Download or read book Climate Variability, Climate Change and Social Vulnerability in the Semi-arid Tropics written by Jesse C. Ribot and published by Cambridge University Press. This book was released on 1996-06-27 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate fluctuations can trigger events that lead to mass migration, hunger and famine. Rather than attributing the blame to nature, the contributors look at the underlying causes of social vulnerability, such as the processes and organisation of society in the semi-arid tropics. Past and present susceptibility to destitution, hunger, and famine in the face of climate variability can teach us about the potential future consequences of climate change. By understanding why individuals, households, nations, and regions are vulnerable, and how they have buffered themselves against climatic and environmental fluctuations, present and future vulnerability can be redressed. Through case studies from across the globe, the authors explore past experiences with climate variability, and the likely effects of, and the possible policy responses to, the types of climatic events that global warming might bring.
Book Synopsis Assessment of the Impacts of Climate Change on Mountain Hydrology by : Walter Vergara
Download or read book Assessment of the Impacts of Climate Change on Mountain Hydrology written by Walter Vergara and published by World Bank Publications. This book was released on 2011 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is beginning to have effects on climate, weather and resource availability in ways that need to be anticipated when planning for the future. In particular, changes in rainfall patterns and temperature may impact the intensity or schedule of water availability. Also the retreat of tropical glaciers, the drying of unique Andean wetland ecosystems, as well as increased weather variability and weather extremes will affect water regulation. These changes have the potential to impact the energy and other sectors, such as agriculture, and could have broader economic effects. Anticipating the impacts of climate change is a new frontier. There are few examples of predictions of the impact of climate change on resource availability and even fewer examples of the applications of such predictions to planning for sustainable economic development. However, having access to an effective methodology would allow planners and policy makers to better plan for adaptation measures to address the consequences of climate change on the power and water sectors. This report presents a summary of the efforts to develop methodological tools for the assessment of climate impacts on surface hydrology in the Peruvian Andes. It is targeted to decision makers in Peru and in other countries to give them guidance on how to choose available and suitable tools and make an assessment of climate impacts on water regulation.
