The National Assessment Overview and Foundation Reports were produced  by the National Assessment Synthesis Team, an advisory committee chartered under the Federal Advisory Committee Act, and were not subjected to OSTP's Information Quality Act Guidelines. The National Assessment was forwarded to the President and Congress in November 2000 for their consideration.

Issues Covered

The Water Resources Sector focused on water quality and human health; extreme events such as flooding and drought; ecosystem function and health; water management and socio-economic impacts; and water use, availability, and resources. All of these issues were analyzed in the context of how potential climate change impacts could be related to other stresses that already exist.

Assessment Approach

The assessment team presented a general summary of major issues of concern and then focused specifically on a few of them. The issues covered in detail are listed above. To assess the impacts of climatic variability and change on the water resources of the U.S., the analysis examined current and anticipated trends in water demand. Quantitative evaluations of potential climate change impacts were based on modeling efforts when available. The assessment process was incorporated with professional review through a special symposium and journal issue of the American Water Resources Association. Cross-cutting issues between sectors were developed at the Water Resources Workshop along with assessment priorities, responsibilities, and a schedule of activities.
