Decision-Support Experiments and Evaluations using Seasonal-to-Interannual Forecasts and Observational Data: A Focus on Water Resources. A Report by the U.S. Climate Change Science Program and the Subcommittee on Global Change Research.
Findings, Summary, and Frequently Asked Questions of the U.S. Climate Change Science Program Synthesis and Assessment Report 5.3 "Decision-Support Experiments and Evaluations using Seasonal-to-Interannual Forecasts and Observational Data: A Focus on Water Resources".
2008 scientific assessment of the effects of global change in the United States, with special emphasis on climate change.
This report is the contribution of Working Group II to the IPCC’s Fourth Assessment Report. It is a comprehensive assessment of the current knowledge of the impacts of climate change, the vulnerability of natural and human environments, and the potential for response through adaptation.
This report synthesizes the contributions of Working Groups I, II, and III to the IPCC’s Fourth Assessment Report, and also draws on recent IPCC Special Reports. It draws together policy-relevant scientific, technical, and socioeconomic information related to climate change, with the goal of assisting governments and other decision makers in formulating and implementing responses.
This report summarizes a workshop that focused on two case studies to provide different perspectives on multiple environmental stressors: 1) drought; 2) atmosphere-ecosphere interactions. Workshop participants identified the development of comprehensive regional frameworks for conducting environmental studies as a key part of understanding multiple environmental stresses.
Report from the U.S. Climate Change Technology Program.
The U.S. Climate Change Science Program (CCSP) held a workshop on November 14-16, 2005, in the Washington, DC, area, addressing the capability of climate science to inform decision making. The workshop served as a forum to address the Program’s progress and future plans regarding its three decision support approaches.
