Regional Climate Trends and Scenarios for the U.s. National Climate Assessment: Part 9. Climate of the Contiguous United States

Publisher Marketing: This publication is one of series of regional climate descriptions designed to provide input that can be used in the development of the National Climate Assessment (NCA). As part of a sustained assessment approach, it is intended that these publications will be updated as new and well-vetted model results are available and as new climate scenario needs become clear. It is also hoped that these publications (and associated data and resources) are of direct benefit to decision makers and communities seeking to use this information in developing adaptation plans. There are nine reports in this series, one each for eight regions defined by the NCA, and one for the contiguous U. S. The eight NCA regions are the Northeast, Southeast, Midwest, Great Plains, Northwest, Southwest, Alaska, and Hawai'i/Pacific Islands. These publications include a description of the observed historical climate conditions for each region and a set of climate scenarios as plausible futures. There are two components of these descriptions. One component is a description of the historical climate conditions in the region. The other component is a description of the climate conditions associated with two future pathways of greenhouse gas emissions.
