Abrupt Climate Change by National Research Council,Division on Earth and Life Studies,Board on Atmospheric Sciences and Climate,Polar Research Board,Ocean Studies Board,Committee on Abrupt Climate Change Pdf

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.

Abrupt Impacts of Climate Change by National Research Council,Division on Earth and Life Studies,Board on Atmospheric Sciences and Climate,Committee on Understanding and Monitoring Abrupt Climate Change and Its Impacts Pdf

Climate is changing, forced out of the range of the past million years by levels of carbon dioxide and other greenhouse gases not seen in the Earth's atmosphere for a very, very long time. Lacking action by the world's nations, it is clear that the planet will be warmer, sea level will rise, and patterns of rainfall will change. But the future is also partly uncertain -- there is considerable uncertainty about how we will arrive at that different climate. Will the changes be gradual, allowing natural systems and societal infrastructure to adjust in a timely fashion? Or will some of the changes be more abrupt, crossing some threshold or "tipping point" to change so fast that the time between when a problem is recognized and when action is required shrinks to the point where orderly adaptation is not possible? Abrupt Impacts of Climate Change is an updated look at the issue of abrupt climate change and its potential impacts. This study differs from previous treatments of abrupt changes by focusing on abrupt climate changes and also abrupt climate impacts that have the potential to severely affect the physical climate system, natural systems, or human systems, often affecting multiple interconnected areas of concern. The primary timescale of concern is years to decades. A key characteristic of these changes is that they can come faster than expected, planned, or budgeted for, forcing more reactive, rather than proactive, modes of behavior. Abrupt Impacts of Climate Change summarizes the state of our knowledge about potential abrupt changes and abrupt climate impacts and categorizes changes that are already occurring, have a high probability of occurrence, or are unlikely to occur. Because of the substantial risks to society and nature posed by abrupt changes, this report recommends the development of an Abrupt Change Early Warning System that would allow for the prediction and possible mitigation of such changes before their societal impacts are severe. Identifying key vulnerabilities can help guide efforts to increase resiliency and avoid large damages from abrupt change in the climate system, or in abrupt impacts of gradual changes in the climate system, and facilitate more informed decisions on the proper balance between mitigation and adaptation. Although there is still much to learn about abrupt climate change and abrupt climate impacts, to willfully ignore the threat of abrupt change could lead to more costs, loss of life, suffering, and environmental degradation. Abrupt Impacts of Climate Change makes the case that the time is here to be serious about the threat of tipping points so as to better anticipate and prepare ourselves for the inevitable surprises.

Abrupt Climate Change by Harunur Rashid,Leonid Polyak,Ellen Mosley-Thompson Pdf

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 193. Abrupt Climate Change: Mechanisms, Patterns, and Impacts brings together a diverse group of paleoproxy records such as ice cores, marine sediments, terrestrial (lakes and speleothems) archives, and coupled ocean-atmosphere climate models to document recent advances in understanding the mechanisms of abrupt climate changes. Since the discovery of the Dansgaard-Oeschger events in Greenland ice cores and the subsequent discovery of their contemporary events in the marine sediments of the North Atlantic, the search for these abrupt, millennial-scale events across the globe has intensified, and as a result, the number of paleoclimatic records chronicling such events has increased. The volume highlights include discussions of records of past climate variability, meridional overturning circulation, land-ocean-atmosphere interactions, feedbacks in the climate system, and global temperature anomalies. Abrupt Climate Change will be of interest to students, researchers, academics, and policy makers who are concerned about abrupt climate change and its potential impact on society.

Climate Crash by John D. Cox Pdf

Physical evidence reveals that centuries of slow, creeping climate variations have actually been punctuated by far more rapid changes. Scientists must now consider the natural threat is greater than once thought.

The Fate of Greenland by Philip W. Conkling,Richard B. Alley,Wallace S. Broecker,George H. Denton Pdf

Viewed from above, Greenland offers an endless vista of whiteness interrupted only by scattered ponds of azure-colored melt water. Ninety percent of Greenland is covered by ice; its ice sheet, the largest outside Antarctica, stretches almost 1,000 miles from north to south and 600 miles from east to west. But this stark view of ice and snow is changing--and changing rapidly. Greenland's ice sheet is melting; the dazzling, photogenic display of icebergs breaking off Greenland's rapidly melting glaciers has become a tourist attraction. The Fate of Greenland documents Greenland's warming with dramatic color photographs and investigates Greenland's climate history for clues about what happens when climate change is abrupt rather than gradual. Geological evidence suggests that Greenland has already been affected by two dramatic changes in climate: the Medieval Warm Period, when warm temperatures in Northern Europe enabled Norse exploration and settlements in Greenland; and the Little Ice Age that followed and apparently wiped out the settlements. Greenland's climate past and present could presage our climate future. Abrupt climate change would be cataclysmic: the melting of Greenland's ice shelf would cause sea levels to rise twenty-four feet worldwide; lower Manhattan would be underwater and Florida's coastline would recede to Orlando. The planet appears to be in a period of acute climate instability, exacerbated by carbon dioxide we pour into the atmosphere. As this book makes clear, it is in all of our interests to pay attention to Greenland.--Publisher description.

The Two-Mile Time Machine by Richard B. Alley Pdf

In the 1990s Richard B. Alley and his colleagues made headlines with the discovery that the last ice age came to an abrupt end over a period of only three years. In The Two-Mile Time Machine, Alley tells the fascinating history of global climate changes as revealed by reading the annual rings of ice from cores drilled in Greenland. He explains that humans have experienced an unusually temperate climate compared to the wild fluctuations that characterized most of prehistory. He warns that our comfortable environment could come to an end in a matter of years and tells us what we need to know in order to understand and perhaps overcome climate changes in the future. In a new preface, the author weighs in on whether our understanding of global climate change has altered in the years since the book was first published, what the latest research tells us, and what he is working on next.

Advancing the Science of Climate Change by National Research Council,Division on Earth and Life Studies,Board on Atmospheric Sciences and Climate,America's Climate Choices: Panel on Advancing the Science of Climate Change Pdf

Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.

Sudden Spring by Rick Van Noy Pdf

The results of climate change make the headlines almost daily. All across America and the globe, communities have to adapt to rising sea levels, intensified storms, and warmer temperatures. One way or another, climate change will be a proving ground. We will either sink, in cases where the land is subsiding, or swim, finding ways to address these challenges. While temperatures and seas are rising slowly, we have some immediate choices to make. If we act quickly and boldly, there is a small window of opportunity to prevent the worst. We can prepare for the changes by understanding what is happening and taking specific measures. There is "commitment" already in the climate change system. To minimize those effects will require another kind of commitment, the kind Rick Van Noy illustrates in these stories about a climate-distressed South. Like Rachel Carson's groundbreaking work Silent Spring, Rick Van Noy's Sudden Spring is a call to action to mitigate the current trends in our environmental degradation. By highlighting stories of people and places adapting to the impacts of a warmer climate, Van Noy shows us what communities in the South are doing to become more climate resilient and to survive a slow deluge of environmental challenges.

The Environment-Conflict Nexus by Francis Galgano Pdf

The aim of this book is to demonstrate how environmental factors have caused an evolution in the landscape of national security since the end of the Cold War. Through relevant case studies, the scope of the problem on the national security landscape due to environmental stressors is illuminated, examined, and synthesized with climate-related data. Human variables such as governance, GDP, and vulnerability are taken into account, and are compared against environmental factors to more accurately determine the causative agents of regional conflicts which threaten national security. These case studies comprise the majority of the text, and they show how individual conflicts are uniquely influenced by environmental stress with variations from situation to situation. This book will be of interest to government and military professionals, and may serve as a resource for college courses in the areas of military geography, international affairs, and sustainability studies.

Climate and Social Stress by National Research Council,Division of Behavioral and Social Sciences and Education,Board on Environmental Change and Society,Committee on Assessing the Impacts of Climate Change on Social and Political Stresses Pdf

Climate change can reasonably be expected to increase the frequency and intensity of a variety of potentially disruptive environmental events-slowly at first, but then more quickly. It is prudent to expect to be surprised by the way in which these events may cascade, or have far-reaching effects. During the coming decade, certain climate-related events will produce consequences that exceed the capacity of the affected societies or global systems to manage; these may have global security implications. Although focused on events outside the United States, Climate and Social Stress: Implications for Security Analysis recommends a range of research and policy actions to create a whole-of-government approach to increasing understanding of complex and contingent connections between climate and security, and to inform choices about adapting to and reducing vulnerability to climate change.

Abrupt Climate Change by Peter U. Clark Pdf

This report is part of a series of 21 Synthesis and Assessments (SAP) aimed at providing current assessments of climate change science to inform public debate, policy, and operational decisions. These reports are also intended to help develop future program research priorities. The guiding vision is to provide the Nation and the global community with the science-based knowledge needed to manage the risks and capture the opportunities associated with climate and related environmental changes. This SAP assesses abrupt climate change events where key aspects of the climate system change faster than the responsible forces would suggest and/or faster than society can respond to those changes.
