Book Description
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

Book Description
Substantial progress has been made in scientific understanding of observed changes in the Earth's climate, the contributions of human and other forces to the observed changes, the qualitative character and quantified range of possible future changes, the consequences of climate change, options for mitigating and adapting to climate change, and the benefits, costs, and other consequences of these actions. The accumulated knowledge is being used to inform a wide variety of decisions in multiple contexts. However, user needs for information that is relevant and directly applicable to risk management decisions at local to regional scales are not being met. Discussions at the IPCC Expert Meeting highlighted a number of reasons for this failure and explored possible remedies. A fundamental shift to a more user-oriented focus is needed, with the goal of providing actionable information for adaptation and mitigation decisions. Success will require greater attention to communication between climate researchers, impact, adaptation, vulnerability, and mitigation researchers, users, and affected populations. Participatory models for research and assessment are effective at producing actionable information and warrant wider adoption. Knowledge gaps that are important for risk management decisions and are priorities for focused research are found at the interfaces of different temporal and spatial scales of analysis and cross-system interactions. Users need information at finer temporal and spatial scales than is commonly provided. Couplings between human systems and biophysical systems are critical determinants of vulnerability, but research is hampered by inadequate social and economic data that are comparable across jurisdictions and that can be spatially correlated with climatic and environmental data. Advances are needed in the understanding and communicating uncertainties, and in decision support tools for managing with uncertainty.Progress in the production and up-take of actionable information will require investments to raise the capacities of research and user communities, and for greater collaborations among researchers and users. The meeting report contains 43 papers. (LN).

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
Climate model results provide the basis for projections of future climate change and increasing numbers of models are likely to contribute to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). The heterogeneity in the new generation of climate models and an increasing emphasis on estimates of uncertainty in the projections raise questions about how best to evaluate and combine model results in order to improve the reliability of projections. Therefore, an Expert Meeting on Assessing and Combining Multi Model Climate Projections was organized by IPCC's Working Group I with contributions from Working Group II (WGI and WGII). The meeting was held in Boulder, Colorado, USA, from 25 to 27 January 2010. It is important for the success of the IPCC AR5 that this discussion took place early in the AR5 assessment cycle. The Expert Meeting provided a platform to explore the possibility of establishing a common framework that is applicable across the two IPCC Working Groups. The scientific core of this meeting report summarises the discussions and conclusions of the Expert Meeting. It contains a stand-alone Good Practice Guidance Paper for IPCC Lead Authors of AR5, as well as for scientists working in model intercomparison projects. The Guidance Paper briefly summarizes methods used in assessing the quality and reliability of climate model simulations and in combining results from multiple models, and provides recommendations for good practice in using multi-model ensembles. Applications include detection and attribution, model evaluation and global climate projections as well as regional projections relevant for impact and adaptation studies. This meeting report further includes the extended abstracts of the presentations and posters from the Expert Meeting as well as a noncomprehensive bibliography of relevant literature. (LN).

Book Description
Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

Book Description
"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.
