Available in PDF, EPUB and Kindle. Book excerpt: The climate record for the past 100,000 years clearly indicates that the climate system has undergone periodic-and often extreme-shifts, sometimes in as little as a decade or less. The causes of abrupt climate changes have not been clearly established, but the triggering of events is likely to be the result of multiple natural processes. Abrupt climate changes of the magnitude seen in the past would have far-reaching implications for human society and ecosystems, including major impacts on energy consumption and water supply demands. Could such a change happen again? Are human activities exacerbating the likelihood of abrupt climate change? What are the potential societal consequences of such a change? Abrupt Climate Change: Inevitable Surprises looks at the current scientific evidence and theoretical understanding to describe what is currently known about abrupt climate change, including patterns and magnitudes, mechanisms, and probability of occurrence. It identifies critical knowledge gaps concerning the potential for future abrupt changes, including those aspects of change most important to society and economies, and outlines a research strategy to close those gaps. Based on the best and most current research available, this book surveys the history of climate change and makes a series of specific recommendations for the future.

Download or read book Atmospheric Processes written by James D. Hanwell and published by Routledge. This book was released on 2019-10-28 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1980, this book is an original approach to the study of the atmosphere at A Level and introductory undergraduate courses. A true understanding of the way the atmosphere works is only attainable on a firm basis of science and the book concentrates on this aspect in a clear and straightforward manner without introducing advanced mathematics. The book discusses the atmosphere in terms of a machine fuelled by the Sun and it deals with the energy involved in global circulations before looking at local processes and finally global patterns. With a clear recognition of the vulnerability of climate to our wellbeing on a global scale, this book remains as relevant now as when it was first published.

Download or read book Decomposing Atmospheric Versus Oceanic Contributions to the High To Low Latitude Teleconnection During a Freshwater Triggered Abrupt Climate Change written by Guanglin Tang and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation we study the high-to-low latitude teleconnection during Younger Dryas-like abrupt climate events using models. The teleconnection considered here is between climate change induced by a freshwater input in high-latitude North Atlantic and global response over the Northern Hemisphere and in the tropics. We focus on three primary questions: (1) What is the relative importance of oceanic vs. atmospheric processes in the teleconnection? (2) What are the respective mechanisms of the atmospheric and oceanic controlled teleconnection? (3) How important is sea surface temperature to the teleconnection, particularly in tropical climate responses. To answer these questions we performed a series of model experiments using an Atmospheric General Circulation Model coupled to a thermodynamic slab ocean model. Previous studies identified a teleconnection between the high-latitude fresh-waterforced abrupt climate change and the low-latitude climate response during a Younger Dryas-like abrupt climate change using coupled Atmosphere-Ocean General Circulation Models. In this study we attempt to separate and compare the atmospheric and oceanic contributions to this teleconnection. The results show that these contributions have comparable climate response magnitudes, but different spatial characteristics with the atmospheric contribution being more zonally symmetric than the oceanic counterpart. Physical atmospheric and oceanic processes are also analyzed to address the second question. It is found that the equator ward propagation of the high-latitude surface cooling is induced by increasing surface sensible heat flux in northern mid-latitudes and subtropics and surface latent heat flux in northern equatorial region. The increase in sensible heat flux is due to cooling of near surface air temperatures, whereas latent heat response is caused by strengthening of the surface trade winds linked to an increase in meridional surface temperature gradient. The oceanic contribution in the North Atlantic is through changes in the oceanic circulation caused by freshwater forcing. To address the third question, we performed additional modelling experiments with same high-latitude forcing but different oceanic mixed layer depths. It is found that change in sea surface temperature is necessary for the high-to-low latitude teleconnection and the tropical precipitation response. To determine the importance of sea surface temperature in Intertropical Convergence Zone (ITCZ) response, we further performed an experiment using a simple model developed by Lindzen and Nigam (1987) and found that the change in sea surface temperature, in concert with lower-tropospheric vertical mixing and surface drag, largely contributes to the simulated ITCZ shift.

Download or read book Understanding Climate Change Feedbacks written by National Research Council and published by National Academies Press. This book was released on 2004-01-02 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade, scientists have learned much about the complex natural processes that influence climate variability and change, and our ability to model climate has increased significantly. We also have begun to better identify those parts of the climate system that are particularly important and not well understood and that therefore limit our ability to project the future evolution of Earth's climate. One of these critical areas is our understanding of the role of feedbacks in the climate system and their role in determining climate sensitivity. Feedbacks are processes in the climate system that can either amplify or dampen the system's response to changed forcings. This study looks at what is known and not known about climate change feedbacks and seeks to identify the feedback processes most in need of improved understanding. It identifies key observations needed to monitor and understand climate feedbacks, discusses ways to evaluate progress in understanding climate feedbacks, recommends ways to improve climate modeling and analysis for climate feedbacks research, and identifies priority areas for research.

Download or read book Global Environmental Change written by National Research Council and published by National Academies Press. This book was released on 1999-09-14 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can we understand and rise to the environmental challenges of global change? One clear answer is to understand the science of global change, not solely in terms of the processes that control changes in climate and the composition of the atmosphere, but in how ecosystems and human society interact with these changes. In the last two decades of the twentieth century, a number of such research effortsâ€"supported by computer and satellite technologyâ€"have been launched. Yet many opportunities for integration remain unexploited, and many fundamental questions remain about the earth's capacity to support a growing human population. This volume encourages a renewed commitment to understanding global change and sets a direction for research in the decade ahead. Through case studies the book explores what can be learned from the lessons of the past 20 years and what are the outstanding scientific questions. Highlights include: Research imperatives and strategies for investigators in the areas of atmospheric chemistry, climate, ecosystem studies, and human dimensions of global change. The context of climate change, including lessons to be gleaned from paleoclimatology. Human responses toâ€"and forcing ofâ€"projected global change. This book offers a comprehensive overview of global change research to date and provides a framework for answering urgent questions.

Download or read book The Ocean Carbon Cycle and Climate written by Mick Follows and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our desire to understand the global carbon cycle and its link to the climate system represents a huge challenge. These overarching questions have driven a great deal of scientific endeavour in recent years: What are the basic oceanic mechanisms which control the oceanic carbon reservoirs and the partitioning of carbon between ocean and atmosphere? How do these mechanisms depend on the state of the climate system and how does the carbon cycle feed back on climate? What is the current rate at which fossil fuel carbon dioxide is absorbed by the oceans and how might this change in the future? To begin to answer these questions we must first understand the distribution of carbon in the ocean, its partitioning between different ocean reservoirs (the "solubility" and "biological" pumps of carbon), the mechanisms controlling these reservoirs, and the relationship of the significant physical and biological processes to the physical environment. The recent surveys from the JGOFS and WOCE (Joint Global Ocean Flux Study and World Ocean Circulation Ex periment) programs have given us a first truly global survey of the physical and biogeochemical properties of the ocean. These new, high quality data provide the opportunity to better quantify the present oceans reservoirs of carbon and the changes due to fossil fuel burning. In addition, diverse process studies and time-series observations have clearly revealed the complexity of interactions between nutrient cycles, ecosystems, the carbon-cycle and the physical envi ronment.

Download or read book Understanding Earth s Deep Past written by National Research Council and published by National Academies Press. This book was released on 2011-08-02 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is little dispute within the scientific community that humans are changing Earth's climate on a decadal to century time-scale. By the end of this century, without a reduction in emissions, atmospheric CO2 is projected to increase to levels that Earth has not experienced for more than 30 million years. As greenhouse gas emissions propel Earth toward a warmer climate state, an improved understanding of climate dynamics in warm environments is needed to inform public policy decisions. In Understanding Earth's Deep Past, the National Research Council reports that rocks and sediments that are millions of years old hold clues to how the Earth's future climate would respond in an environment with high levels of atmospheric greenhouse gases. Understanding Earth's Deep Past provides an assessment of both the demonstrated and underdeveloped potential of the deep-time geologic record to inform us about the dynamics of the global climate system. The report describes past climate changes, and discusses potential impacts of high levels of atmospheric greenhouse gases on regional climates, water resources, marine and terrestrial ecosystems, and the cycling of life-sustaining elements. While revealing gaps in scientific knowledge of past climate states, the report highlights a range of high priority research issues with potential for major advances in the scientific understanding of climate processes. This proposed integrated, deep-time climate research program would study how climate responded over Earth's different climate states, examine how climate responds to increased atmospheric carbon dioxide and other greenhouse gases, and clarify the processes that lead to anomalously warm polar and tropical regions and the impact on marine and terrestrial life. In addition to outlining a research agenda, Understanding Earth's Deep Past proposes an implementation strategy that will be an invaluable resource to decision-makers in the field, as well as the research community, advocacy organizations, government agencies, and college professors and students.
