Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.

"While there are examples of successful weapon systems acquisition programs within the U.S. Air Force (USAF), many of the programs are still incurring cost growth, schedule delays, and performance problems. The USAF now faces serious challenges in acquiring and maintaining its weapons systems as it strives to maintain its current programs; add new capabilities to counter evolving threats; and reduce its overall program expenditures. Owning the technical baseline is a critical component of the Air Forces ability to regain and maintain acquisition excellence. Owning the technical baseline allows the government acquisition team to manage and respond knowledgeably and effectively to systems development, operations, and execution, thereby avoiding technical and other programmatic barriers to mission success. Additionally, owning the technical baseline ensures that government personnel understand the user requirements, why a particular design and its various features have been selected over competing designs, and what the options are to pursue alternative paths to the final product given unanticipated cost, schedule, and performance challenges. Owning the Technical Baseline for Acquisition Programs in the U.S. Air Force discusses the strategic value to the Air Force of owning the technical baseline and the risk of not owning it and highlights key aspects of how agencies other than the Air Force own the technical baseline for their acquisition programs. This report identifies specific barriers to owning the technical baseline for the Air Force and makes recommendations to help guide the Air Force in overcoming those barriers"--Publisher's description.

Because of the role of innovation as a driver of economic productivity and growth and as a mechanism for improving people's well-being in other ways, understanding the nature, determinants, and impacts of innovation has become increasingly important to policy makers. To be effective, investment in innovation requires this understanding, which, in turn, requires measurement of the underlying inputs and subsequent outcomes of innovation processes. In May 2016, at the request of the National Center for Science and Engineering Statistics of the National Science Foundation, the Committee on National Statistics of the National Academies of Sciences, Engineering, and Medicine convened a workshop - bringing together academic researchers, private and public sector experts, and representatives from public policy agencies - to develop strategies for broadening and modernizing innovation information systems.This publication summarizes the presentation and discussion of the event.

"A report of the National Academies of Sciences, Engineering, Medicine"

Although people in the United States have historically been reasonably supportive of federal censuses and surveys, they are increasingly unavailable for or not willing to respond to interview requests from federal--as well as private--sources. Moreover, even when people agree to respond to a survey, they increasingly decline to complete all questions, and both survey and item nonresponse are growing problems. In March 2016, the National Academies of Sciences, Engineering, and Medicine convened a workshop to consider the respondent burden and its challenges and opportunities of the American Community Survey, which is conducted by the U.S. Census Bureau. This publication summarizes the presentations and discussions from the workshop.

The decay product of the medical isotope molybdenum-99 (Mo-99), technetium-99m (Tc-99m), and associated medical isotopes iodine-131 (I-131) and xenon-133 (Xe-133) are used worldwide for medical diagnostic imaging or therapy. The United States consumes about half of the world's supply of Mo-99, but there has been no domestic (i.e., U.S.-based) production of this isotope since the late 1980s. The United States imports Mo-99 for domestic use from Australia, Canada, Europe, and South Africa. Mo-99 and Tc-99m cannot be stockpiled for use because of their short half-lives. Consequently, they must be routinely produced and delivered to medical imaging centers. Almost all Mo-99 for medical use is produced by irradiating highly enriched uranium (HEU) targets in research reactors, several of which are over 50 years old and are approaching the end of their operating lives. Unanticipated and extended shutdowns of some of these old reactors have resulted in severe Mo-99 supply shortages in the United States and other countries. Some of these shortages have disrupted the delivery of medical care. Molybdenum-99 for Medical Imaging examines the production and utilization of Mo-99 and associated medical isotopes, and provides recommendations for medical use.

The process of discovering and developing a new drug or therapy is extremely costly and time consuming, and recently, it has been estimated that the creation of a new medicine costs on average more than $2 billion and takes 10 years to reach patients. The challenges associated with bringing new medicines to market have led many pharmaceutical companies to seek out innovative methods for streamlining their drug discovery research. One way to increase the odds of success for compounds in the drug development pipeline is to adopt genetically guided strategies for drug discovery, and recognizing the potential benefits of collecting genetic and phenotypic information across specific populations, pharmaceutical companies have started collaborating with healthcare systems and private companies that have curated genetic bioresources, or large databases of genomic information. Large-scale cohort studies offer an effective way to collect and store information that can be used to assess gene-environment interactions, identify new potential drug targets, understand the role of certain genetic variants in the drug response, and further elucidate the underlying mechanisms of disease onset and progression. To examine how genetic bioresources could be used to improve drug discovery and target validation, the National Academies of Sciences, Engineering, and Medicine hosted a workshop in March 2016. Participants at the workshop explored the current landscape of genomics-enabled drug discovery activities in industry, academia, and government; examined enabling partnerships and business models; and considered gaps and best practices for collecting population data for the purpose of improving the drug discovery process. This publication summarizes the presentations and discussions from the workshop.

"A report of the National Academies of Sciences, Engineering, Medicine"

NASA operates a large number of space science missions, approximately three-quarters of which are currently in their extended operations phase. They represent not only a majority of operational space science missions, but a substantial national investment and vital national assets. They are tremendously scientifically productive, making many of the major discoveries that are reported in the media and that rewrite textbooks. Extending Science - NASA's Space Science Mission Extensions and the Senior Review Process evaluates the scientific benefits of missions extensions, the current process for extending missions, the current biennial requirement for senior reviews of mission extensions, the balance between starting new missions and extending operating missions, and potential innovative cost-reduction proposals for extended missions, and makes recommendations based on this review.

"Nanoscale science, engineering, and technology, often referred to simply as "nanotechnology," is the understanding, characterization, and control of matter at the scale of nanometers, the dimension of atoms and molecules. Advances in nanotechnology promise new materials and structures that are the basis of solutions, for example, for improving human health, optimizing available energy and water resources, supporting a vibrant economy, raising the standard of living, and increasing national security. Established in 2001, the National Nanotechnology Initiative (NNI) is a coordinated, multiagency effort with the mission to expedite the discovery, development, and deployment of nanoscale science and technology to serve the public good. This report is the latest triennial review of the NNI called for by the 21st Century Nanotechnology Research and Development Act of 2003. It examines and comments on the mechanisms in use by the NNI to advance focused areas of nanotechnology towards advanced development and commercialization and on the physical and human infrastructure needs for successful realization in the United States of the benefits of nanotechnology development"--Publisher's description.

"It is not yet 60 years since the first artificial satellite was placed into Earth orbit. In just over a half century, mankind has gone from no presence in outer space to a condition of high dependence on orbiting satellites. These sensors, receivers, transmitters, and other such devices, as well as the satellites that carry them, are components of complex space systems that include terrestrial elements, electronic links between and among components, organizations to provide the management, care and feeding, and launch systems that put satellites into orbit. In many instances, these space systems connect with and otherwise interact with terrestrial systems; for example, a very long list of Earth-based systems cannot function properly without information from the Global Positioning System (GPS). Space systems are fundamental to the information business, and the modern world is an information-driven one. In addition to navigation (and associated timing), space systems provide communications and imagery and other Earth-sensing functions. Among these systems are many that support military, intelligence, and other national security functions of the United States and many other nations. Some of these are unique government, national security systems; however, functions to support national security are also provided by commercial and civil-government space systems."--

Even as the U.S. population becomes steadily more diverse, minorities and women remain underrepresented in clinical trials to develop new drugs and medical devices. Although progress in increasing minority participation in clinical trials has occurred, participation rates do not fully represent the overall population of minorities in the United States. This underrepresentation threatens the health of both these populations and the general population, since greater minority representation could reveal factors that affect health in all populations. Federal legislation has sought to increase the representation of minorities and women in clinical trials, but legislation by itself has not been sufficient to overcome the many barriers to greater participation. Only much broader changes will bring about the meaningful participation of all population groups in the clinical research needed to improve health. To examine the barriers to participation in clinical trials and ways of overcoming those barriers, the National Academies of Sciences, Engineering, and Medicine held a workshop in April 2015. This publication summarizes the presentations and discussions from the workshop.

"Our world is changing at an accelerating rate. The global human population has grown from 6.1 billion to 7.1 billion in the last 15 years and is projected to reach 11.2 billion by the end of the century. The distribution of humans across the globe has also shifted, with more than 50 percent of the global population now living in urban areas, compared to 29 percent in 1950. Along with these trends, increasing energy demands, expanding industrial activities, and intensification of agricultural activities worldwide have in turn led to changes in emissions that have altered the composition of the atmosphere. The Future of Atmospheric Chemistry Research: Remembering Yesterday, Understanding Today, Anticipating Tomorrow summarizes the rationale and need for supporting a comprehensive U.S. research program in atmospheric chemistry; comments on the broad trends in laboratory, field, satellite, and modeling studies of atmospheric chemistry; determines the priority areas of research for advancing the basic science of atmospheric chemistry; and identifies the highest priority needs for improvements in the research infrastructure to address those priority research topics. This report describes the scientific advances over the past decade in six core areas of atmospheric chemistry: emissions, chemical transformation, oxidants, atmospheric dynamics and circulation, aerosol particles and clouds, and biogeochemical cycles and deposition. This material was developed for the NSF's Atmospheric Chemistry Program; however, the findings will be of interest to other agencies and programs that support atmospheric chemistry research"--

An estimated 90 percent of oncology patients in the United States receive treatment in outpatient cancer centers and clinics. This change from the older model of inpatient care has important implications for overall quality of care for oncology patients and nutritional care in particular. Amidst growing concern about access to oncology nutrition services, combined with growing recognition of the importance of providing nutritional care to optimize oncology treatment outcomes and maximize quality of life among both patients and survivors of cancer, the National Academies of Sciences, Engineering, and Medicine convened a public workshop in March 2016 to explore evolving interactions between nutritional care, cancer, and health outcomes. Participants explored how health outcomes and survival of cancer patients in outpatient cancer centers are affected by current standards for nutritional services, nutritional interventions, and benefits associated with oncology patient access to medical nutrition therapy. They also studied the cost of outpatient nutritional care and assessed cost-benefit relationships between oncology nutrition services and health outcomes and survival. This publication summarizes the presentations and discussions from the workshop.

"A critical component of the nation's economic vitality is ensuring that all Americans can contribute and prosper. Such contributions presuppose an intentional focus on achieving the highest levels of health possible, which requires that conditions in communities, schools, workplaces, and other settings promote health and address the social determinants of health for all community members. Many organizations, in both the private and public sectors, have been establishing partnerships to further healthy workplaces and health equity in general. Many are taking the lead in producing economic growth that is inclusive and responsive to the nation's diverse needs and populations. Increasingly, private-public partnerships are emerging as ways of doing business. Additionally, a variety of new developments in health, health care, and community benefits obligations that are part of the Affordable Care Act have contributed to this interest in economic growth and health and in the creation of new partnerships. To examine past successes and future opportunities, the National Academies of Sciences, Engineering, and Medicine held a workshop in November 2015. The workshop focused on the potential of the private sector to produce a triple bottom line: economic opportunity (including workforce development) and growth, healthy work and community environments, and improved employee health. At the same time, participants looked beyond the private sector to public-private partnerships and to public-sector actions that combine opportunities for economic growth and good health for all. This publication summarizes the presentations and discussions from the workshop"--Publisher's description.

On March 3-4, 2016, the National Academies of Sciences, Engineering, and Medicine's Forum on Neuroscience and Nervous System Disorders held a workshop in Washington, DC, bringing together key stakeholders to discuss opportunities for improving the integrity, efficiency, and validity of clinical trials for nervous system disorders. Participants in the workshop represented a range of diverse perspectives, including individuals not normally associated with traditional clinical trials. The purpose of this workshop was to generate discussion about not only what is feasible now, but what may be possible with the implementation of cutting-edge technologies in the future.

Science is a way of knowing about the world. At once a process, a product, and an institution, science enables people to both engage in the construction of new knowledge as well as use information to achieve desired ends. Access to science--whether using knowledge or creating it--necessitates some level of familiarity with the enterprise and practice of science: we refer to this as science literacy. Science literacy is desirable not only for individuals, but also for the health and well- being of communities and society. More than just basic knowledge of science facts, contemporary definitions of science literacy have expanded to include understandings of scientific processes and practices, familiarity with how science and scientists work, a capacity to weigh and evaluate the products of science, and an ability to engage in civic decisions about the value of science. Although science literacy has traditionally been seen as the responsibility of individuals, individuals are nested within communities that are nested within societies--and, as a result, individual science literacy is limited or enhanced by the circumstances of that nesting. Science Literacy studies the role of science literacy in public support of science. This report synthesizes the available research literature on science literacy, makes recommendations on the need to improve the understanding of science and scientific research in the United States, and considers the relationship between scientific literacy and support for and use of science and research.

Children with disabilities and complex medical and educational needs present a special challenge for policy makers and practitioners. These children exhibit tremendous heterogeneity in their conditions and needs, requiring a varied array of services to meet those needs. Uneven public and professional awareness of their conditions and a research base marked by significant gaps have led to programs, practices, and policies that are inconsistent in quality and coverage. Parents often have to navigate and coordinate, largely on their own, a variety of social, medical, and educational support services, adding to the already daunting financial, logistical, and emotional challenges of raising children with special needs. The unmet needs of children with disabilities and complex medical and educational needs can cause great suffering for these children and for those who love and care for them. To examine how systems can be configured to meet the needs of children and families as they struggle with disabilities and complex health and educational needs, the National Academies of Sciences, Engineering, and Medicine held a workshop in December 2015. The goal of the workshop was to highlight the main barriers and promising solutions for improving care and outcome of children with complex medical and educational needs. Workshop participants examined prevention, care, service coordination, and other topics relevant to children with disabilities and complex health and educational needs, along with their families and caregivers. More broadly, the workshop seeks actionable understanding on key research questions for enhancing the evidence base; promoting and sustaining the quality, accessibility, and use of relevant programs and services; and informing relevant policy development and implementation. By engaging in dialogue to connect the prevention, treatment, and implementation sciences with settings where children are seen and cared for, the forum seeks to improve the lives of children by improving the systems that affect those children and their families. This publications summarizes the presentations and discussions from the workshop.

In February 2016, the National Academies of Sciences, Engineering, and Medicine held a workshop to explore options for expanding the Substance Abuse and Mental Health Services Administration's (SAMHSA) behavioral health data collections to include measures of recovery from substance use and mental disorder. Participants discussed options for collecting data and producing estimates of recovery from substance use and mental disorders, including available measures and associated possible data collection mechanisms. This publication summarizes the presentations and discussions from the workshop.

New Worlds, New Horizons in Astronomy and Astrophysics (NWNH), the report of the 2010 decadal survey of astronomy and astrophysics, put forward a vision for a decade of transformative exploration at the frontiers of astrophysics. This vision included mapping the first stars and galaxies as they emerge from the collapse of dark matter and cold clumps of hydrogen, finding new worlds in a startlingly diverse population of extrasolar planets, and exploiting the vastness and extreme conditions of the universe to reveal new information about the fundamental laws of nature. NWNH outlined a compelling program for understanding the cosmic order and for opening new fields of inquiry through the discovery areas of gravitational waves, time-domain astronomy, and habitable planets. Many of these discoveries are likely to be enabled by cyber-discovery and the power of mathematics, physics, and imagination. To help realize this vision, NWNH recommended a suite of innovative and powerful facilities, along with balanced, strong support for the scientific community engaged in theory, data analysis, technology development, and measurements with existing and new instrumentation. Already in the first half of the decade, scientists and teams of scientists working with these cutting-edge instruments and with new capabilities in data collection and analysis have made spectacular discoveries that advance the NWNH vision. New Worlds, New Horizons: A Midterm Assessment reviews the responses of NASA's Astrophysics program, NSF's Astronomy program, and DOE's Cosmic Frontiers program to NWNH. This report describes the most significant scientific discoveries, technical advances, and relevant programmatic changes in astronomy and astrophysics over the years since the publication of the decadal survey, and assesses how well the Agencies' programs address the strategies, goals, and priorities outlined in the 2010 decadal survey.

In 2012, the National Defense Authorization Act (NDAA), section 818, outlined new requirements for industry to serve as the lead in averting counterfeits in the defense supply chain. Subsequently, the House Armed Services Committee, in its report on the Fiscal Year 2016 NDAA, noted that the pending sale of IBM's microprocessor fabrication facilities to Global Foundries created uncertainty about future access of the United States to trusted state-of-the-art microelectronic components and directed the Comptroller General to assess the Department of Defense's (DoD's) actions and measures to address this threat. In this context, the National Academies of Sciences, Engineering, and Medicine convened a workshop to facilitate an open dialogue with leading industry, academic, and government experts to (1) define the current technological and policy challenges with maintaining a reliable and secure source of microelectronic components; (2) review the current state of acquisition processes within the Air Force for acquiring reliable and secure microelectronic components; and (3) explore options for possible business models within the national security complex that would be relevant for the Air Force acquisition community. This publication summarizes the results of the workshop.

Historically, the United States has been a world leader in aerospace endeavors in both the government and commercial sectors. A key factor in aerospace leadership is continuous development of advanced technology, which is critical to U.S. ambitions in space, including a human mission to Mars. To continue to achieve progress, NASA is currently executing a series of aeronautics and space technology programs using a roadmapping process to identify technology needs and improve the management of its technology development portfolio. NASA created a set of 14 draft technology roadmaps in 2010 to guide the development of space technologies. In 2015, NASA issued a revised set of roadmaps. A significant new aspect of the update has been the effort to assess the relevance of the technologies by listing the enabling and enhancing technologies for specific design reference missions (DRMs) from the Human Exploration and Operations Mission Directorate and the Science Mission Directorate. NASA Space Technology Roadmaps and Priorities Revisited prioritizes new technologies in the 2015 roadmaps and recommends a methodology for conducting independent reviews of future updates to NASA's space technology roadmaps, which are expected to occur every 4 years.

"In September 2015, the National Academies of Sciences, Engineering, and Medicine hosted a workshop to explore the basic and translational research needs for population health science, and to discuss specific research priorities and actions to foster population health improvement. The workshop was designed to provide frameworks for understanding population health research and its role in shaping and having an effect on population health, identify individual and institutional facilitators and challenges regarding the production, communication, and use of research for population health improvement, and identify key areas for future research critical to the advancement of population health improvement. This publication summarizes the presentations and discussions from the workshop"--

A decade ago, the U.S. chemical industry was in decline. Of the more than 40 chemical manufacturing plants being built worldwide in the mid-2000s with more than $1 billion in capitalization, none were under construction in the United States. Today, as a result of abundant domestic supplies of affordable natural gas and natural gas liquids resulting from the dramatic rise in shale gas production, the U.S. chemical industry has gone from the world's highest-cost producer in 2005 to among the lowest-cost producers today. The low cost and increased supply of natural gas and natural gas liquids provides an opportunity to discover and develop new catalysts and processes to enable the direct conversion of natural gas and natural gas liquids into value-added chemicals with a lower carbon footprint. The economic implications of developing advanced technologies to utilize and process natural gas and natural gas liquids for chemical production could be significant, as commodity, intermediate, and fine chemicals represent a higher-economic-value use of shale gas compared with its use as a fuel. To better understand the opportunities for catalysis research in an era of shifting feedstocks for chemical production and to identify the gaps in the current research portfolio, the National Academies of Sciences, Engineering, and Medicine conducted an interactive, multidisciplinary workshop in March 2016. The goal of this workshop was to identify advances in catalysis that can enable the United States to fully realize the potential of the shale gas revolution for the U.S. chemical industry and, as a result, to help target the efforts of U.S. researchers and funding agencies on those areas of science and technology development that are most critical to achieving these advances. This publication summarizes the presentations and discussions from the workshop.

Gulf Coast communities and natural resources suffered extensive direct and indirect damage as a result of the largest accidental oil spill in US history, referred to as the Deepwater Horizon (DWH) oil spill. Notably, natural resources affected by this major spill include wetlands, coastal beaches and barrier islands, coastal and marine wildlife, seagrass beds, oyster reefs, commercial fisheries, deep benthos, and coral reefs, among other habitats and species. Losses include an estimated 20% reduction in commercial fishery landings across the Gulf of Mexico and damage to as much as 1,100 linear miles of coastal salt marsh wetlands. This historic spill is being followed by a restoration effort unparalleled in complexity and magnitude in U.S. history. Legal settlements in the wake of DWH led to the establishment of a set of programs tasked with administering and supporting DWH-related restoration in the Gulf of Mexico. In order to ensure that restoration goals are met and money is well spent, restoration monitoring and evaluation should be an integral part of those programs. However, evaluations of past restoration efforts have shown that monitoring is often inadequate or even absent. Effective Monitoring to Evaluate Ecological Restoration in the Gulf of Mexico identifies best practices for monitoring and evaluating restoration activities to improve the performance of restoration programs and increase the effectiveness and longevity of restoration projects. This report provides general guidance for restoration monitoring, assessment, and synthesis that can be applied to most ecological restoration supported by these major programs given their similarities in restoration goals. It also offers specific guidance for a subset of habitats and taxa to be restored in the Gulf including oyster reefs, tidal wetlands, and seagrass habitats, as well as a variety of birds, sea turtles, and marine mammals.

In February 2016, the National Academies of Sciences, Engineering, and Medicine held a workshop in which speakers shared strategies for individuals, organizations, and communities to advance racial and health equity. Participants discussed increasing awareness about the role of historical contexts and dominant narratives in interpreting data and information about different racial and ethnic groups, framing messages for different social and political outcomes, and readying people to institutionalize practices, policies, and partnerships that advance racial and health equity. This publication serves as a factual summary of the presentations and discussions from the workshop.

In March 2015, the National Academies of Sciences, Engineering, and Medicine held a workshop to explore the role that chemical exposures may play in the development of obesity. The obesity epidemic that has gripped the United States and much of the developed world for the past several decades has proved remarkably resistant to the various approaches tried by clinicians and public health officials to fight it. This raises the possibility that, in addition to the continued exploration of consumer understanding and behavior, new approaches that go beyond the standard focus on energy intake and expenditure may also be needed to combat the multifactorial problem of obesity. The speakers at the workshop discussed evidence from both studies with animal models and human epidemiological studies that exposure to environmental chemicals is linked both to weight gain and to glucose tolerance, insulin sensitivity, inflammation, and other aspects of the metabolic syndrome. In addition to conventional environmental chemical exposures, this workshop also included one panel to discuss the potential role of other exposures, including sugar, artificial sweeteners, and antibiotics, in aiding or causing obesity. The participants also examined possible biological pathways and mechanisms underlying the potential linkages. This publication summarizes the presentations and discussions from the workshop.

Decades of research have demonstrated that the parent-child dyad and the environment of the family--which includes all primary caregivers--are at the foundation of children's well- being and healthy development. From birth, children are learning and rely on parents and the other caregivers in their lives to protect and care for them. The impact of parents may never be greater than during the earliest years of life, when a child's brain is rapidly developing and when nearly all of her or his experiences are created and shaped by parents and the family environment. Parents help children build and refine their knowledge and skills, charting a trajectory for their health and well-being during childhood and beyond. The experience of parenting also impacts parents themselves. For instance, parenting can enrich and give focus to parents' lives; generate stress or calm; and create any number of emotions, including feelings of happiness, sadness, fulfillment, and anger. Parenting of young children today takes place in the context of significant ongoing developments. These include: a rapidly growing body of science on early childhood, increases in funding for programs and services for families, changing demographics of the U.S. population, and greater diversity of family structure. Additionally, parenting is increasingly being shaped by technology and increased access to information about parenting. Parenting Matters identifies parenting knowledge, attitudes, and practices associated with positive developmental outcomes in children ages 0-8; universal/preventive and targeted strategies used in a variety of settings that have been effective with parents of young children and that support the identified knowledge, attitudes, and practices; and barriers to and facilitators for parents' use of practices that lead to healthy child outcomes as well as their participation in effective programs and services. This report makes recommendations directed at an array of stakeholders, for promoting the wide-scale adoption of effective programs and services for parents and on areas that warrant further research to inform policy and practice. It is meant to serve as a roadmap for the future of parenting policy, research, and practice in the United States.

"Many factors contribute to variability in Earth's climate on a range of timescales, from seasons to decades. Natural climate variability arises from two different sources: (1) internal variability from interactions among components of the climate system, for example, between the ocean and the atmosphere, and (2) natural external forcings, such as variations in the amount of radiation from the Sun. External forcings on the climate system also arise from some human activities, such as the emission of greenhouse gases (GHGs) and aerosols. The climate that we experience is a combination of all of these factors. Understanding climate variability on the decadal timescale is important to decision-making. Planners and policy makers want information about decadal variability in order to make decisions in a range of sectors, including for infrastructure, water resources, agriculture, and energy. In September 2015, the National Academies of Sciences, Engineering, and Medicine convened a workshop to examine variability in Earth's climate on decadal timescales, defined as 10 to 30 years. During the workshop, ocean and climate scientists reviewed the state of the science of decadal climate variability and its relationship to rates of human-caused global warming, and they explored opportunities for improvement in modeling and observations and assessing knowledge gaps. Frontiers in Decadal Climate Variability summarizes the presentations and discussions from the workshop"--Publisher's description.
