- Guidance Documents for Lifecycle Management of ETDs
In 2011, a research team led by the University of North Texas, the Educopia Institute/MetaArchive Cooperative, and the worldwide Networked Digital Library of Theses and Dissertations (NDLTD), began studying the production, dissemination, and preservation of Electronic Theses and Dissertations (ETDs). The original intent was to develop and disseminate documentation for academic libraries that would help curators better understand and address the preservation challenges presented by these new digital collections. As researchers from the libraries of University of North Texas, Virginia Tech, Rice University, Boston College, Indiana State University, Penn State, and the University of Arizona began to grapple with ETD lifecycle management issues, they quickly realized that librarians were but one of many academic stakeholder groups that work collaboratively to produce and maintain ETD collections. Studying the library role in isolation was neither feasible nor helpful. The scope of our work increased to encompass the roles and responsibilities of core stakeholders in the ETD lifecycle: students, faculty, administrators, technologists, commercial vendors, and librarians. The resulting Guidance Documents address areas of interest to ETD program planners, managers, and curators. They will help this extended set of stakeholders understand, document, and address the administrative, legal, and technical challenges presented by ETDs—from submission to long-term preservation. The authors have aimed to be comprehensive in their treatment of ETD programs, and encourage readers to review all of the Guidance Document to gain a holistic view. However, they have also highlighted the sections of each document relevant to 4 roles in ETD programs: institutional administrators, submission staff, access and repository staff, and IT staff.
- Guidelines for Digital Newspaper Preservation Readiness
The Guidelines for Digital Newspaper Preservation Readiness address a specific set of preservation challenges faced by libraries, archives, historical societies, and other organizations that curate substantial collections of digital newspaper content. The Guidelines are intended to inform curators and collection managers at libraries, archives, historical societies, and other such memory organizations about various practical readiness activities that they can take. They provide links to technical resources that curators can either implement themselves or work with their technical staff to implement. The Guidelines (Version 1.0) only deal with digital newspapers at this point, not broadcast or other forms of digital news. digital.library.unt.edu/ark:/67531/metadc282586/

- Does Every Research Library Need a Digital Humanities Center?
The essay discusses specific concerns of digital humanists in hopes of bridging the gap between how library directors and digital humanities researchers think. It suggests many ways to respond to the needs of digital humanists, and creating a Digital Humanities center is appropriate in relatively few circumstances. The essay recommends that a “Digital Humanities-friendly” environment may be more effective than a Digital Humanities Center but that library culture may need to evolve in order for librarians to be seen as effective Digital Humanities partners. The authors conclude that what we call “The Digital Humanities” today will soon be considered “The Humanities.” Supporting Digital Humanities scholarship is not much different than supporting digital scholarship in any discipline. Increasingly, digital scholarship is simply scholarship. digital.library.unt.edu/ark:/67531/metadc272207/
- Participatory Design in Academic Libraries: New Reports and Findings
This report looks at how staff at eight academic institutions gained new insight about how students and faculty use their libraries, and how the staff are using these findings to improve library technologies, space, and services. Participatory design is a relatively recent approach to understanding library user behavior. It is based on techniques used in anthropological and ethnographic observation. The report is based on a series of presentations at the second CLIR Seminar on Participatory Design of Academic Libraries, held at the University of Rochester’s River Campus June 5-7, 2013. Chapters focus on projects at the University of Colorado, Boulder; Colby College; University of Connecticut; Columbia University; Rush University Medical Center; Purdue University; Northwestern University; and the University of Rochester. David Lindahl, of the University of Missouri-Kansas City, provided the keynote. digital.library.unt.edu/ark:/67531/metadc282584/
- Research Data Management Principles, Practices, and Prospects
This report examines how research institutions are responding to data management requirements of the National Science Foundation, National Institutes of Health, and other federal agencies. It also considers what role, if any, academic libraries and the library and information science profession should have in supporting researchers’ data management needs. University of North Texas (UNT) Library Director Martin Halbert opens the report with an overview of the DataRes Project, a two-year investigation of data management practices conducted at UNT with colleagues Spencer D. C. Keralis, Shannon Stark, and William E. Moen. His introduction is followed by a series of papers that were presented at the DataRes Symposium that UNT organized in December 2012. digital.library.unt.edu/ark:/67531/metadc234929/
- Searching for Sustainability: Strategies from Eight Digitized Special Collections
This report aims to address one of the biggest challenges facing libraries and cultural heritage organizations: how to move their special collections into the 21st century through digitization while developing successful strategies to make sure those collections remain accessible and relevant over time. Through a cooperative agreement as part of the National Leadership Grants Program, the Institute of Museum and Library Services (IMLS) funded the Association of Research Libraries (ARL), in partnership with Ithaka S+R, to undertake in-depth case studies of institutions that have worked to build the audience, infrastructure, and funding models necessary to maintain and grow their digital collections.
The eight collections profiled provide useful models and examples of good practice for project leaders to consider when digitizing their own materials. We hope that these case studies will encourage greater discussion among individuals in the academic library and cultural heritage communities about the reasons why they invest so much time and energy in the creation and ongoing management of their digitized special collections, the goals they set for them, and the planning needed to realize those aims. These questions become even more pressing in an environment where the traditional sources of funding for digitization are beginning to wane. In the coming years, the ability to identify secure sources of support and to demonstrate impact over time will undoubtedly become increasingly important. digital.library.unt.edu/ark:/67531/metadc234918/
- Born Digital: Guidance for Donors, Dealers, and Archival Repositories
The report provides recommendations to help ensure the physical and intellectual well-being of materials created and managed in digital form ("born digital") that are transferred from donors to archival repositories.
The report is presented in four sections, each of which provides an overview of a key area of concern: initial collection review, privacy and intellectual property, key stages in acquiring digital materials, and post-acquisition review by the repository. Each section concludes with two lists of recommendations: one for donors and dealers, and a second for repository staff. Appendixes provide more specific information about possible staffing activities, as well as a list of resources and ready-to-use checklists that incorporate recommendations from throughout the report. Ten archivists and curators from institutions in the United States and United Kingdom collaborated on the report. digital.library.unt.edu/ark:/67531/metadc234935/
- Library Publishing Directory 2014
The first edition of the Library Publishing Directory provides a snapshot of the publishing activities of 115 academic and research libraries, including information about the number and types of publications they produce, the services they offer authors, how they are staffed and funded, and the future plans of institutions that are engaged in this emerging field. In documenting the breadth and depth of activities in this field, this resource aims to articulate the unique value of library publishing; establish it as a significant and growing community of practice; and to raise its visibility within a number of stakeholder communities, including administrators, funding agencies, other scholarly publishers, librarians, and content creators. Specifically it is hoped that this Directory will: • Introduce all readers to the emerging field of library publishing and help articulate its unique characteristics as a distinctive "publishing field." • Facilitate collaboration among library publishers and other publishing entities, especially the university presses and learned societies that share their values. • Alert authors of scholarly content to a range of potential publishing partners dedicated to supporting their experimentation with new forms of scholarly communication and open access business models. The Directory is also available Open Access in several electronic formats through www.librarypublishing.org. digital.library.unt.edu/ark:/67531/metadc234934/
- The Ithaka S+R US Faculty Survey 2012
The Ithaka S+R US Faculty Survey has focused since its inception on capturing an accurate picture of faculty members' practices, attitudes, and needs. In the fifth triennial cycle, fielded in fall 2012, the survey focused on research and teaching practices broadly, as well as the dissemination, collecting, discovery, and access of research and teaching materials. Findings from this cycle of the Ithaka S+R US Faculty Survey will provide colleges and universities, libraries, learned societies, and academic publishers with insight into the evolving attitudes and practices of faculty members in the context of substantial environmental change for higher education.
The development of the 2012 questionnaire was guided by an advisory committee of librarians, publishers, policy makers, and a scholarly society executive. The overall project was supported by some 20 colleges and universities, learned societies, and publishers / vendors. digital.library.unt.edu/ark:/67531/metadc234917/

- The Digital Public Domain: Foundations for an Open Culture
Digital technology has made culture more accessible than ever before. Texts, audio, pictures and video can easily be produced, disseminated, used and remixed using devices that are increasingly user-friendly and affordable. However, along with this technological democratization comes a paradoxical flipside: the norms regulating culture's use — copyright and related rights — have become increasingly restrictive. This book brings together essays by academics, librarians, entrepreneurs, activists and policy makers, who were all part of the EU-funded Communia project. Together the authors argue that the Public Domain — that is, the informational works owned by all of us, be that literature, music, the output of scientific research, educational material or public sector information — is fundamental to a healthy society. The essays range from more theoretical papers on the history of copyright and the Public Domain, to practical examples and case studies of recent projects that have engaged with the principles of Open Access and Creative Commons licensing. digital.library.unt.edu/ark:/67531/metadc123530/

- Policy Guidelines for the Development and Promotion of Open Access
UNESCO issued this publication to demystify the concept of Open Access (OA) and to provide concrete steps on putting relevant policies in place. Building capacities in Member States for Open Access is a necessary but not sufficient condition for promotion of the concept. Creating an enabling policy environment for OA is therefore a priority.
This publication will serve the needs of OA policy development at the government, institutional and funding agency level. The overall objective of the Policy Guidelines is to promote Open Access in Member States by facilitating understanding of all relevant issues related to Open Access. The guidelines are not prescriptive in nature, but are suggestive to facilitate knowledge-based decision-making to adopt OA policies and strengthen national research systems. digital.library.unt.edu/ark:/67531/metadc141806/

- Global Climate Change Impacts in the United States: Highlights
This booklet highlights key findings of Global Climate Change Impacts in the United States, a state of knowledge report about the observed and projected consequences of climate change for our nation and people. It is an authoritative scientific report written in plain language, with the goal of better informing public and private decision making at all levels. The report draws from a large body of scientific information including the set of 21 synthesis and assessment products from the U.S. Global Change Research Program, the assessments of the Intergovernmental Panel on Climate Change, and much more. It also includes new information published since these assessments were released. While the primary focus of the report is on the impacts of climate change in the United States, it also discusses some of the actions society is already taking or can take to respond to the climate challenge. These include limiting climate change by, for example, reducing emissions of heat-trapping gases or increasing their removal from the atmosphere. The importance of our current choices about heat-trapping emissions is underscored by comparing impacts resulting from higher versus lower emissions scenarios. Choices about emissions made now will have far-reaching consequences for climate change impacts, with lower emissions reducing the magnitude of climate change impacts and the rate at which they appear. The report also identifies examples of options currently being pursued to cope with or adapt to the impacts of climate change and/or other environmental issues. One example of adaptation is included in this booklet. There is generally insufficient information at present to evaluate the effectiveness, costs, and benefits of potential adaptation actions. This booklet includes a brief overview of the 10 key findings of the report, using examples from the report to illustrate each finding. References for material in this booklet, including figures, can be found in the full report. digital.library.unt.edu/ark:/67531/metadc11959/
- IPCC Expert Meeting on the Science of Alternative Metrics: Meeting Report
This extended report of the IPCC Expert Meeting on the Science of Alternative Metrics that was held in Oslo 18-20 March 2009 is provided in response to an invitation from the UN Framework Convention on Climate Change Ad Hoc Working Group on Further
Commitments for Annex I Parties under Kyoto Protocol (UNFCCC AWG-KP) to the Intergovernmental Panel on Climate Change (IPCC)
to undertake further technical assessment of alternative common metrics which are used to calculate the CO2 equivalence of anthropogenic emissions by sources, and removals by sinks, of greenhouse gases listed in Annex A to the Kyoto Protocol.
The outcome of the expert meeting was an agreed set of key conclusions and recommendations to UNFCCC in response to the request of the AWG-KP as well as more specific recommendations to the scientific community regarding research needs and ones relevant to the scoping of the IPCC's Fifth Assessment Report (AR5). These were presented to the IPCC Plenary in a short report at its 30th
session in Antalya, 21-23 April 2009. The current full report of the expert meeting amplifies those conclusions and recommendations
and includes the extended abstracts of the meeting presentations as well as a general bibliography. digital.library.unt.edu/ark:/67531/metadc11872/

- Coastal Sensitivity to Sea-Level Rise: A Focus on the Mid-Atlantic Region
This document is part of the Synthesis and Assessment Products described in the U.S. Climate Change Science Program (CCSP) Strategic Plan. The U.S. Government's CCSP is responsible for providing the best science-based knowledge possible to inform management of the risks and opportunities associated with changes in the climate and related environmental systems. To support its mission, the CCSP has commissioned 21 "synthesis and assessment products" (SAPs) to advance decision making on climate change-related issues by providing current evaluations of climate change science and identifying priorities for research, observation, and decision support. This Synthesis and Assessment Product (SAP), developed as part of the U.S. Climate Change Science Program, examines potential effects of sea-level rise from climate change during the twenty-first century, with a focus on the mid-Atlantic coast of the United States. Using scientific literature and policy-related documents, the SAP describes the physical environments; potential changes to coastal environments, wetlands, and vulnerable species; societal impacts and implications of sea-level rise; decisions that may be sensitive to sea-level rise; opportunities for adaptation; and institutional barriers to adaptation. digital.library.unt.edu/ark:/67531/metadc12028/
- Decision-Support Experiments and Evaluations using Seasonal-to-Interannual Forecasts and Observational Data: A Focus on Water Resources
This Synthesis and Assessment Product focuses on the connection between the scientific ability to predict climate on seasonal scales and the opportunity to incorporate such understanding into water resource management decisions. It directly addresses decision support experiments and evaluations that have used seasonal-to-interannual forecasts and observational data, and is expected to inform (1) decision makers about the relative success of experiences of others who have experimented with these forecasts and data in resource management; (2) climatologists, hydrologists, and social scientists on how to advance the delivery of decision-support resources that use the most recent forecast products, methodologies, and tools; and (3) science and resource managers as they plan for future investments in research related to forecasts and their role in decision support. It is important to note, however, that while the focus of this Product is on the water resources management sector, the findings within this Synthesis and Assessment Product may be directly transferred to other sectors. digital.library.unt.edu/ark:/67531/metadc12037/
- Global Climate Change Impacts in the United States: A State of Knowledge Report from the U.S. Global Change Research Program
This book is the most comprehensive report to date on the wide range of impacts of climate change in the United States. It is written in plain language to better inform members of the public and policymakers. The report finds that global warming is unequivocal, primarily human-induced, and its impacts are already apparent in transportation, agriculture, health, and water and energy supplies. These impacts are expected to grow with continued climate change - the higher the levels of greenhouse gas emissions, the greater the impacts. The report illustrates how these impacts can be kept to a minimum if greenhouse gas emissions are reduced. The choices we make now will determine the severity of climate change impacts in the future. This book will help citizens, business leaders, and policymakers at all levels to make informed decisions about responding to climate change and its impacts.

- Past Climate Variability and Change in the Arctic and at High Latitudes
This Climate Change Science Program Synthesis and Assessment Product addresses current capabilities to integrate observations of the climate system into a consistent description of past and current conditions through the method of reanalysis. In addition, the Product assesses present capabilities to attribute causes for climate variations and trends over North America during the reanalysis period, which extends from the mid-twentieth century to the present.
This Product reviews Past Climate Variability and Change in the Arctic and at High Latitudes. Paleoclimate records play a key role in our understanding of Earth's past and present climate system and in our confidence in predicting future climate changes. Paleoclimate data help to elucidate past and present active mechanisms of climate change by placing the short instrumental record into a longer term context and by permitting models to be tested beyond the limited time that instrumental measurements have been available. Recent observations in the Arctic have identified large ongoing changes and important climate feedback mechanisms that multiply the effects of global-scale climate changes. As discussed in this report, paleoclimate data show that land and sea ice have grown with cooling temperatures and have shrunk with warming ones, amplifying temperature changes while causing and responding to ecosystem shifts and sea-level changes. digital.library.unt.edu/ark:/67531/metadc12018/
- Thresholds of Climate Change in Ecosystems
This Report (SAP 4.2) focuses on the thresholds of Climate Change in Ecosystems. As defined in this Synthesis and Assessment Report, 'an ecological threshold is the point at which there is an abrupt change in an ecosystem quality, property, or phenomenon, or where small changes in one or more external conditions produce large and persistent responses in an ecosystem'.Ecological thresholds occur when external factors, positive feedbacks, or nonlinear instabilities in a system cause changes to propagate in a domino-like fashion that is potentially irreversible. This report reviews threshold changes in North American ecosystems that are potentially induced by climatic change and addresses the significant challenges these threshold crossings impose on resource and land managers. Sudden changes to ecosystems and the goods and services they provide are not well understood, but they are extremely important if natural resource managers are to succeed in developing adaptation strategies in a changing world. The report provides an overview of what is known about ecological thresholds and where they are likely to occur. It also identifies those areas where research is most needed to improve knowledge and understand the uncertainties regarding them. The report suggests a suite of potential actions that land and resource managers could use to improve the likelihood of success for the resources they manage, even under conditions of incomplete understanding of what drives thresholds of change and when changes will occur. digital.library.unt.edu/ark:/67531/metadc12029/
- Trends in Emissions of Ozone-Depleting Substances, Ozone Layer Recovery, and Implications for Ultraviolet Radiation Exposure
This Synthesis and Assessment Product (SAP 2.4) focuses on the Climate models. Depletion of the stratospheric ozone layer by human-produced ozone-depleting substances has been recognized as a global environmental issue for more than three decades, and the international effort to address the issue via the United Nations Montreal Protocol marked its 20-year anniversary in 2007. Scientific understanding underpinned the Protocol at its inception and ever since. As scientific knowledge advanced and evolved, the Protocol evolved through amendment and adjustment. Policy-relevant science has documented the rise, and now the beginning decline, of the atmospheric abundances of many ozone-depleting substances in response to actions taken by the nations of the world. Projections are for a return of ozone-depleting chemicals (compounds containing chlorine and bromine) to their "pre-ozone-depletion" (pre-1980) levels by the middle of this century for the midlatitudes; the polar regions are expected to follow suit within 20 years after that. Since the 1980s, global ozone sustained a depletion of about 5 percent in the midlatitudes of both the Northern Hemisphere and Southern Hemisphere, where most of the Earth's population resides; it is now showing signs of turning the corner towards increasing ozone. The large seasonal depletions in the polar regions are likely to continue over the next decade but are expected to subside over the next few decades. digital.library.unt.edu/ark:/67531/metadc12023/
- Analyses of the Effects of Global Change on Human Health and Welfare and Human Systems
This document is part of the Synthesis and Assessment Products (SAP) described in the U.S. Climate Change Science Program (CCSP) Strategic Plan. This report is meant to synthesize and communicate the current state of understanding about the characteristics and implications of uncertainty related to climate change and variability to an audience of policymakers, decision makers, and members of the media and general public with an interest in developing a fundamental understanding of the issue. digital.library.unt.edu/ark:/67531/metadc12033/
- Climate Projections Based on Emissions Scenarios for Long-Lived and Short-Lived Radiatively Active Gases and Aerosols
This report focuses on the Climate Projections Based on Emissions Scenarios. The influence of greenhouse gases and particle pollution on our present and future climate has been widely examined. While both long-lived (e.g., carbon dioxide) and short-lived (e.g., soot) gases and particles affect the climate, other projections of future climate, such as the IPCC reports focus largely on the long-lived gases. This U.S. Climate Change Science Program Synthesis and Assessment Product provides a different emphasis. The authors examine the effect of long-lived greenhouse gases on the global climate based on updated emissions scenarios produced by another CCSP Synthesis and Assessment Product (SAP 2.1a). In these scenarios, atmospheric concentrations of the long-lived greenhouse gases leveled off, or stabilized, at predetermined levels by the end of the twenty-first century (unlike in the IPCC scenarios). However, the projected future temperature changes fall within the same range as those projected for the latest IPCC report. The authors confirm the robust future warming signature and other associated changes in the climate. digital.library.unt.edu/ark:/67531/metadc12025/
- The United States National Report on Systematic Observations for Climate for 2008: National Activities with Respect to the Global Climate Observing System (GCOS) Implementation Plan
Long-term, high-accuracy, stable environmental observations are essential to define the state of the global integrated Earth system, its history and its future variability and change. Observations for climate include: (1) operational weather observations, when appropriate care has been exercised to establish high accuracy; (2) limited-duration observations collected as part of research investigations to elucidate chemical, dynamical, biological, or radiative processes that contribute to maintaining climate patterns or to their variability; (3) high accuracy, high precision observations to document decadal-to-centennial changes; and (4) observations of climate proxies, collected to extend the instrumental climate record to remote regions and back in time to provide information on climate change at millennial and longer time scales. This report was requested by the United Nations Framework Convention on Climate Change (UNFCCC) in order to serve as input to see how progress has been made with respect to the Global Climate Observing System (GCOS) Implementation Plan developed in 2004 In accordance with the UNFCCC guidelines, the sections of the report delineate specific U.S. climate monitoring activities in several distinct yet integrated areas as follows: (1) common issues; (2) non-satellite atmospheric observations; (3) non-satellite oceanic observations; (4) non-satellite terrestrial observations; (5) satellite global atmospheric, oceanic, and terrestrial observations; and (6) data and information management related to systematic observations. The various federal agencies involved in observing the environment provide the required long-term observations. Space-based systems provide unique global measurements of solar output, the Earth's radiation budget; vegetation type and primary production; land surface conditions; ocean and terrestrial biomass primary productivity; tropospheric and stratospheric ozone; tropospheric and stratospheric water vapor; tropospheric aerosols; greenhouse gas distributions; sea level; ocean surface conditions and winds; weather; and tropical precipitation, among others. digital.library.unt.edu/ark:/67531/metadc11945/

- Climate Models: An Assessment of Strengths and Limitations
This Synthesis and Assessment Product (SAP 3.1) focuses on the Climate models. Scientists extensively use mathematical models of Earth's climate, executed on the most powerful computers available, to examine hypotheses about past and present-day climates. Development of climate models is fully consistent with approaches being taken in many other fields of science dealing with very complex systems. These climate simulations provide a framework within which enhanced understanding of climate-relevant processes, along with improved observations, are merged into coherent projections of future climate change. This report describes the models and their ability to simulate current climate. digital.library.unt.edu/ark:/67531/metadc12024/

- Preliminary Review of Adaptation Options for Climate-Sensitive Ecosystems and Resources
The U.S. Government's Climate Change Science Program (CCSP) is responsible for providing the best science-based knowledge possible to inform management of the risks and opportunities associated with changes in the climate and related environmental systems. To support its mission, the CCSP has commissioned 21 "synthesis and assessment products" (SAPs) to advance decision making on climate change-related issues by providing current evaluations of climate change science and identifying priorities for research, observation, and decision support. This Report-SAP 4.4-focuses on federally managed lands and waters to provide a "Preliminary Review of Adaptation Options for Climate-Sensitive Ecosystems and Resources." It is one of seven reports that support Goal 4 of the CCSP Strategic Plan to understand the sensitivity and adaptability of different natural and managed ecosystems and human systems to climate and related global changes.
The purpose of SAP 4.4 is to provide useful information on the state of knowledge regarding adaptation options for key, representative ecosystems and resources that may be sensitive to climate variability and change. As its title suggests, this report is a preliminary review, defined as "the process of collecting and reviewing available information about known or potential adaptation options." digital.library.unt.edu/ark:/67531/metadc12031/
- Ting and the Possible Futures
This is a children's book where the characters build a time machine that lets them visit alternate futures based on the decisions they make in the present. The story provides a glimpse of a post-apocalyptic dystopia as a result of severe global climate change, as well as a future utopian ideal that comes as a result of implementing massive changes to land use and food and energy production. digital.library.unt.edu/ark:/67531/metadc28542/
- Weather and Climate Extremes in a Changing Climate. Regions of Focus: North America, Hawaii, Caribbean, and U.S. Pacific Islands
This document is part of the Synthesis and Assessment Products described in the U.S. Climate Change Science Program (CCSP) Strategic Plan. Changes in extreme weather and climate events have significant impacts and are among the most serious challenges to society in coping with a changing climate. This Synthesis and Assessment Product (SAP 3.3) focuses on weather and climate extremes in a changing climate. Many extremes and their associated impacts are now changing. For example, in recent decades most of North America has been experiencing more unusually hot days and nights, fewer unusually cold days and nights, and fewer frost days. Heavy downpours have become more frequent and intense. Droughts are becoming more severe in some regions, though there are no clear trends for North America as a whole. The power and frequency of Atlantic hurricanes have increased substantially in recent decades, though North American mainland land-falling hurricanes do not appear to have increased over the past century. Outside the tropics, storm tracks are shifting northward and the strongest storms are becoming even stronger. It is well established through formal attribution studies that the global warming of the past 50 years is due primarily to human-induced increases in heat-trapping gases. Such studies have only recently been used to determine the causes of some changes in extremes at the scale of a continent. Certain aspects of observed increases in temperature extremes have been linked to human influences. The increase in heavy precipitation events is associated with an increase in water vapor, and the latter has been attributed to human-induced warming. No formal attribution studies for changes in drought severity in North America have been attempted. There is evidence suggesting a human contribution to recent changes in hurricane activity as well as in storms outside the tropics, though a confident assessment will require further study. digital.library.unt.edu/ark:/67531/metadc12026/
- Common Ground: Solutions for reducing the human, economic and conservation costs of human wildlife conflict
This report deals with the conflicts between wildlife and human development. Three cases studies are included, in Namibia, Nepal and Indonesia, respectively. Each location has different problems and contexts, but in all three countries, human lives and economic livelihoods are at stake, as well as the loss of habitat of threatened species. The authors advocate a species conservation approach based on land use planning integrated with human needs in order continue sustainable development. digital.library.unt.edu/ark:/67531/metadc32900/
- The Effects of Climate Change on Agriculture, Land Resources, Water Resources, and Biodiversity in the United States
This document is a part of the Synthesis and Assessment Products described in the U.S. Climate Change Science Program Strategic Plan. The report describes how climate affects the design, construction, safety, operations, and maintenance of transportation infrastructure and systems. The prospect of a changing climate raises critical questions regarding how alterations in temperature, precipitation, storm events, and other aspects of the climate could affect the nation's roads, airports, rail, transit systems, pipelines, ports, and waterways. Phase I of this regional assessment of climate change and its potential impacts on transportation systems addresses these questions for the region of the U.S. central Gulf Coast between Galveston, Texas and Mobile, Alabama. digital.library.unt.edu/ark:/67531/metadc12030/
- Revised Research Plan for the U.S. Climate Change Science Program
This Revised Research Plan is an update to the 2003 Strategic Plan of the US Climate Change Science Program (CCSP), a document that was developed via a thorough, open and transparent multi-year process involving a wide range of scientists and managers. The Strategic Plan has long-term value to CCSP, but like any strategic plan, it must be supplemented by shorter-term revisions that take into account both advances in the science and changes in societal needs, and CCSP has an ongoing long-range strategic planning process to ensure that these needs are met. The Revised Research Plan (hereinafter referred to as the Research Plan) draws on CCSP's long-range planning process and provides this update, in compliance with the terms of the Global Change Research Act (GCRA) of 1990.
In the Research Plan, the reader will find several things:
1) an updated statement of vision, goals and capabilities consistent with CCSP's current Strategic Plan but reflecting both scientific progress and the evolution of the Program based on accomplishments and evolving societal and environmental needs;
2) a description of the relationship of the Research Plan to the current Scientific Assessment;
3) highlights of ways in which the program is evolving in the context of the progress made over the years 2003-2007 since the Strategic Plan was put in place, and a description of the priorities that have emerged as a result;
4) a description of research plans for the coming years, in order to build upon the work envisioned in the Strategic Plan and begun over the past four years. digital.library.unt.edu/ark:/67531/metadc11855/
