Book Description
SciDAC has invested heavily in climate change research. We offer a candid opinion as to the impact of the DOE laboratories' SciDAC projects on the upcoming Fourth Assessment Report of the Intergovernmental Panel on Climate Change. As a result of the direct importance of climate change to society, climate change research is highly coordinated at the international level. The Intergovernmental Panel on Climate Change (IPCC) is charged with providing regular reports on the state of climate change research to government policymakers. These reports are the product of thousands of scientists efforts. A series of reviews involving both scientists and policymakers make them among the most reviewed documents produced in any scientific field. The high profile of these reports acts a driver to many researchers in the climate sciences. The Fourth Assessment Report (AR4) is scheduled to be released in 2007. SciDAC sponsored research has enabled the United States climate modeling community to make significant contributions to this report. Two large multi-Laboratory SciDAC projects are directly relevant to the activities of the IPCC. The first, entitled ''Collaborative Design and Development of the Community Climate System Model for Terascale Computers'', has made important software contributions to the recently released third version of the Community Climate System Model (CCSM3.0) developed at the National Center for Atmospheric Research. This is a multi-institutional project involving Los Alamos National Laboratory, Oak Ridge National Laboratory, Lawrence Berkeley National Laboratory, Pacific Northwest National Laboratory, Argonne National Laboratory, Lawrence Livermore National Laboratory and the National Center for Atmospheric Research. The original principal investigators were Robert Malone and John B. Drake. The current principal investigators are Phil Jones and John B. Drake. The second project, entitled ''Earth System Grid II: Turning Climate Datasets into Community Resources'' aims to facilitate the distribution of the copious amounts of data produced by coupled climate model integrations to the general scientific community. This is also a multi-institutional project involving Argonne National Laboratory, Oak Ridge National Laboratory, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory and the National Center for Atmospheric Research. The principal investigators are Ian Foster, Don Middleton and Dean Williams. Perhaps most significant among the activities of the ''Collaborative Design'', project was the development of an efficient multi-processor coupling package. CCSM3.0 is an extraordinarily complicated physics code. The fully coupled model consists of separate submodels of the atmosphere, ocean, sea ice and land. In addition, comprehensive biogeochemistry and atmospheric chemistry submodels are under intensive current development. Each of these submodels is a large and sophisticated program in its own right. Furthermore, in the coupled model, each of the submodels, including the coupler, is a separate multiprocessor executable program. The coupler package must efficiently coordinate the communication as well as interpolate or aggregate information between these programs. This regridding function is necessary because each major subsystem (air, water or surface) is allowed to have its own independent grid.

Book Description
The recent release of the Intergovernmental Panel on Climate Change (IPCC) 4th Assessment Report (AR4) has generated significant media attention. Much has been said about the U.S. role in this report, which included significant support from the Department of Energy through the Scientific Discovery through Advanced Computing (SciDAC) and other Department of Energy (DOE) programs for climate model development and the production execution of simulations. The SciDAC-supported Earth System Grid Center for Enabling Technologies (ESG-CET) also played a major role in the IPCC AR4: all of the simulation data that went into the report was made available to climate scientists worldwide exclusively via the ESG-CET. At the same time as the IPCC AR4 database was being developed, the National Center for Atmospheric Research (NCAR), a leading U.S. climate science laboratory and a ESG participant, began publishing model runs from the Community Climate System Model (CCSM), and its predecessor the Parallel Coupled Model (PCM) through ESG. In aggregate, ESG-CET provides seamless access to over 250 terabytes of distributed climate simulation data to over 6,000 registered users worldwide, who have taken delivery of more than 280 terabytes from the archive. Not only does this represent a substantial advance in scientific knowledge, it is also a major step forward in how we conduct the research process on a global scale. Moving forward, the next IPCC assessment report, AR5, will demand multi-site metadata federation for data discovery and cross-domain identity management for single signon of users in a more diverse federation enterprise environment. Towards this aim, ESG is leading the effort in the climate community towards standardization of material for the global federation of metadata, security, and data services required to standardize, analyze, and access data worldwide.

Book Description
The U.S. Climate Change Science Program (CCSP) coordinates the efforts of 13 federal agencies to understand why climate is changing, to improve predictions about how it will change in the future, and to use that information to assess impacts on human systems and ecosystems and to better support decision making. Evaluating Progress of the U.S. Climate Change Science Program is the first review of the CCSP's progress since the program was established in 2002. It lays out a method for evaluating the CCSP, and uses that method to assess the strengths and weaknesses of the entire program and to identify areas where progress has not met expectations. The committee found that the program has made good progress in documenting and understanding temperature trends and related environmental changes on a global scale, as well as in understanding the influence of human activities on these observed changes. The ability to predict future climate changes also has improved, but efforts to understand the impacts of such changes on society and analyze mitigation and adaptation strategies are still relatively immature. The program also has not met expectations in supporting decision making, studying regional impacts, and communicating with a wider group of stakeholders.

Book Description
Climate change is one of the most important global environmental problems facing the world today. Policy decisions are already being made to limit or adapt to climate change and its impacts, but there is a need for greater integration between science and decision making. This book proposes six priorities for restructuring the United States' climate change research program to develop a more robust knowledge base and support informed responses: Reorganize the Program Around Integrated Scientific-Societal Issues Establish a U.S. Climate Observing System Support a New Generation of Coupled Earth System Models Strengthen Research on Adaptation, Mitigation, and Vulnerability Initiate a National Assessment of the Risks and Costs of Climate Change Impacts and Options to Respond Coordinate Federal Efforts to Provide Climate Information, Tools, and Forecasts Routinely to Decision Makers

Book Description
The report reviews a draft strategic plan from the U.S. Climate Change Science Program, a program formed in 2002 to coordinate and direct U.S. efforts in climate change and global change research. The U.S. Climate Change Science Program incorporates the decade-old Global Change Research Program and adds a new component -the Climate Change Research Initiative-whose primary goal is to "measurably improve the integration of scientific knowledge, including measures of uncertainty, into effective decision support systems and resources."

Book Description
While every mode of transportation in the U.S. will be affected as the climate changes, potentially the greatest impact on transportation systems will be flooding of roads, railways, transit systems, and airport runways in coastal areas because of rising sea levels and surges brought on by more intense storms, says a new report from the National Research Council. Though the impacts of climate change will vary by region, it is certain they will be widespread and costly in human and economic terms, and will require significant changes in the planning, design, construction, operation, and maintenance of transportation systems. The U.S. transportation system was designed and built for local weather and climate conditions, predicated on historical temperature and precipitation data. The report finds that climate predictions used by transportation planners and engineers may no longer be reliable, however, in the face of new weather and climate extremes. Infrastructure pushed beyond the range for which it was designed can become stressed and fail, as seen with loss of the U.S. 90 Bridge in New Orleans after Hurricane Katrina.

Book Description
In May 2001, the Administration asked the National Academy of Sciences - National Research Council (NRC) to provide an updated evaluation of key questions about climate change science. Upon receipt of the NRC's report in June 2001, the President directed the relevant agencies and departments of the federal government to build on the extensive U.S. Global Change Research Program (USGCRP) to accelerate research on the most important uncertainties in climate science, enhance climate observation systems, and improve information available to decisionmakers. To accom- plish this, the Administration took several steps: The President launched the Climate Change Research Initiative (CCRI) in June 2001, with an enhanced focus on the climate effects of aerosols (tiny particles) in the atmosphere, the carbon cycle in the Earth system, climate mod- eling, observations, and development of scien- tific information to support decisionmaking. The President created a new, cabinet-level organization in February 2002, to improve the government-wide management of climate sci- ence and climate-related technology develop- ment. Two collaborative interagency programs were launched in response to the President's direction: the Climate Change Science Program (CCSP) and the Climate Change Technology Program In July 2002, a year-long process to prepare a 10-year strategic plan for the CCSP was initiat- ed. This planning process was designed to ensure a comprehensive examination of research and observation needs, transparent review by all the international scientific and stakeholder communities, and establishment of defined goals for the research. This document, together with the companion CCSP scientific strategic plan, represents the culmination of the planning and public review process. The United States has also launched an interna- tional effort to design and implement a com- prehensive, multilaterally sponsored Earth observing system, which will provide critical information to improve climate science and modeling. This system will build directly upon the major advances in observations and data management already achieved by the United States and other nations. A ministerial meeting hosted by the U.S. government in Washington in July 2003 is the first step in a planned 10- year effort to greatly improve the ability to "take the temperature of the Earth." Vision and Goals Research and observations can play unique roles in helping society to deal with key climate change issues. This gives rise to the guiding vision of the U.S. Climate Change Science Program.

Book Description
Climate change seems to be an insurmountable problem. Political solutions have so far had little impact. Some scientists are now advocating the so-called 'Plan B', a more direct way of reducing the rate of future warming by reflecting more sunlight back to space, creating a thermostat in the sky. In this book, Mike Hulme argues against this kind of hubristic techno-fix. Drawing upon a distinguished career studying the science, politics and ethics of climate change, he shows why using science to fix the global climate is undesirable, ungovernable and unattainable. Science and technology should instead serve the more pragmatic goals of increasing societal resilience to weather risks, improving regional air quality and driving forward an energy technology transition. Seeking to reset the planet’s thermostat is not the answer.

Book Description
Human activities are yielding rising atmospheric concentrations of greenhouse gases and other gases and particulates and are also greatly altering the Earth¿s land cover. These activities, if allowed to continue unabated, will have extensive, highly uncertain, but potentially serious and costly impacts on regional climates and ocean conditions throughout the world. Here is an overview of the current understanding of the impacts of climate change in the U.S., emphasizing the wide range of uncertainty about the magnitude and timing of those impacts and the implications of that uncertainty for the formulation of effective policy responses. Provides a conceptual framework for addressing climate change as an economic concern. Illustrations.
