Book Description
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.

Book Description
Changes in climate are driven by natural and human-induced perturbations of the Earth's energy balance. These climate drivers or "forcings" include variations in greenhouse gases, aerosols, land use, and the amount of energy Earth receives from the Sun. Although climate throughout Earth's history has varied from "snowball" conditions with global ice cover to "hothouse" conditions when glaciers all but disappeared, the climate over the past 10,000 years has been remarkably stable and favorable to human civilization. Increasing evidence points to a large human impact on global climate over the past century. The report reviews current knowledge of climate forcings and recommends critical research needed to improve understanding. Whereas emphasis to date has been on how these climate forcings affect global mean temperature, the report finds that regional variation and climate impacts other than temperature deserve increased attention.

Book Description
Climate Change: Evidence and Causes is a jointly produced publication of The US National Academy of Sciences and The Royal Society. Written by a UK-US team of leading climate scientists and reviewed by climate scientists and others, the publication is intended as a brief, readable reference document for decision makers, policy makers, educators, and other individuals seeking authoritative information on the some of the questions that continue to be asked. Climate Change makes clear what is well-established and where understanding is still developing. It echoes and builds upon the long history of climate-related work from both national academies, as well as on the newest climate-change assessment from the United Nations' Intergovernmental Panel on Climate Change. It touches on current areas of active debate and ongoing research, such as the link between ocean heat content and the rate of warming.

Book Description
Research Paper (undergraduate) from the year 2019 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, grade: 1.3, University of Bonn, language: English, abstract: At first this work will look at the different aspects of the cryosphere and the changes that occur in these different areas. As the cryosphere includes many different aspects, only the changes occurring in the following aspects will be examined: sea ice, glaciers and ice sheets, and permafrost. Afterwards a selection of small-scale impacts from these changes on different aspects of human life aspects will be explained. Here the wide range of different aspects of human life, which will be affected by these changes will be shown. In the end the findings will be concluded and an outlook into the future will be given. Climate change is one of the biggest challenges that humanity is facing today. It will cause, global effects that will have severe impacts on many aspects of human life (IPPC 2014). But some areas of the world will be more affected by these changes than others. One of these areas is the cryosphere. The global cryosphere encompasses all aspects of the frozen realm, including glaciers and ice sheets, sea ice, lake and river ice, permafrost, seasonal snow, and ice crystals in the atmosphere. There are three mayor cryosphere regions, these are: Antarctica, the Arctic Ocean and the extra polar snow and mountain environments. As these mountain ranges are located all over the globe, cryosphere areas can even be found along the equator. Climate change will be felt earlier and more severely in the cryosphere and in the arctic regions, than the rest of the world. This is the case because as snow cover, sea ice and ice sheets diminish, this will produce further warming as the albedo in these areas decreases. Changes in these areas due to climate change will have severe impact on the human way of life. Especially native inhabitants of these cryosphere areas will be affected, as they have lesser capabilities to adapt to these changes, which threaten their way of life. In this paper we will focus on the social and economic impacts of these changes, with a special focus on how native arctic inhabitants will be affected. They deserve a special focus as they are most affected by these changes, while only contributing little to the anthropogenic climate change.

Book Description
Society today may be more vulnerable to global-scale, long-term, climate change than ever before. Even without any human influence, past records show that climate can be expected to continue to undergo considerable change over decades to centuries. Measures for adaption and mitigation will call for policy decisions based on a sound scientific foundation. Better understanding and prediction of climate variations can be achieved most efficiently through a nationally recognized "dec-cen" science plan. This book articulates the scientific issues that must be addressed to advance us efficiently toward that understanding and outlines the data collection and modeling needed.

Book Description
The Alfred Wegener Institute Earth System Model (AWI-ESM) is applied to study the role of the Greenland Ice Sheet (GIS) in different future warming scenarios. The model includes an interactive Ice Sheet Model (ISM) to capture ice sheet dynamics and enhance the representation of spatial freshwater discharge. The ISM leads to a strong decadal variability to the freshwater release, resulting in intervals in which it reduces the surface runoff by high accumulation rates. This compensating effect is missing in climate models without dynamic ice sheets. To investigate processes involved in the buildup phase of ice sheets, transient simulations of the Last Glacial Inception (LGI) are performed. These cooling climate simulations complement the future warming scenarios. The model is run asynchronously from 125 ka to 110 ka with prescribed orbital and greenhouse gas forcing. Large-scale glaciation occurs in a simulation with implemented anomaly coupling. This anomaly coupling is applied to compensate for model biases in high-latitude near-surface air temperature. Large areas of Quebec and Baffin Island glaciate, mainly driven by the thickening of snowfields. In order to assess the effects of heat and freshwater fluxes by iceberg melting on deep-ocean characteristics, multi-centennial simulations under fixed pre-industrial forcing are run with a fully coupled ESM including interactive icebergs. Compared to simulations without interactive icebergs, the results show a cooling of deep ocean water masses and enhanced deep water formation in the continental shelf area of the Ross Sea, a process commonly underestimated by current climate models. The results emphasize the importance of realistically representing both heat and freshwater fluxes in the high southern latitudes.

Book Description
Emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch where human activities will largely determine the evolution of Earth's climate. Because carbon dioxide in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe. Emissions reductions decisions made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia. According to Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia, important policy decisions can be informed by recent advances in climate science that quantify the relationships between increases in carbon dioxide and global warming, related climate changes, and resulting impacts, such as changes in streamflow, wildfires, crop productivity, extreme hot summers, and sea level rise. One way to inform these choices is to consider the projected climate changes and impacts that would occur if greenhouse gases in the atmosphere were stabilized at a particular concentration level. The book quantifies the outcomes of different stabilization targets for greenhouse gas concentrations using analyses and information drawn from the scientific literature. Although it does not recommend or justify any particular stabilization target, it does provide important scientific insights about the relationships among emissions, greenhouse gas concentrations, temperatures, and impacts. Climate Stabilization Targets emphasizes the importance of 21st century choices regarding long-term climate stabilization. It is a useful resource for scientists, educators and policy makers, among others.

Book Description
This book demystifies the models we use to simulate present and future climates, allowing readers to better understand how to use climate model results. In order to predict the future trajectory of the Earth’s climate, climate-system simulation models are necessary. When and how do we trust climate model predictions? The book offers a framework for answering this question. It provides readers with a basic primer on climate and climate change, and offers non-technical explanations for how climate models are constructed, why they are uncertain, and what level of confidence we should place in them. It presents current results and the key uncertainties concerning them. Uncertainty is not a weakness but understanding uncertainty is a strength and a key part of using any model, including climate models. Case studies of how climate model output has been used and how it might be used in the future are provided. The ultimate goal of this book is to promote a better understanding of the structure and uncertainties of climate models among users, including scientists, engineers and policymakers.
