NOAA has released a set of state climate summaries containing information on historical climate variations and trends, future climate model projections of climate conditions, and past and future conditions of sea level and coastal flooding. They also provide context and linkage to other agency resources for climate resilience planning, such as downscaled climate data for subregions and watershed vulnerability assessment tools. Each of these regional reports summarizes observed and projected climate and hydrological patterns cited in reputable peer-reviewed literature and authoritative national and regional reports, and characterizes climate threats to USACE business lines, (e.g., flood risk management). Geological Survey (USGS) Hydrologic Unit Codes (HUC) across the continental United States, Alaska, Hawaii, and Puerto Rico. USACE has begun releasing a series of 21 regional climate syntheses at the scale of 2-digit U.S. Regional Climate Change and Hydrology Literature Syntheses This will allow local communities to better account for these factors when they plan future urban and suburban development, manufacturing facilities, and transportation and other infrastructure. Department of Transportation project to develop planning scenarios that incorporate projected changes in land use, population, urbanization, and climate. The Responses to Climate Change Program is also supporting USACE Albuquerque District participation in the Central New Mexico Climate Change Scenario Planning Project, a U.S. For example, the program supported USACE Albuquerque District participation in the Bureau of Reclamation-led Upper Rio Grande Impact Assessment, which examined current climate trends in and model projections of future climate in the Rio Grande Basin above Elephant Butte and the resulting impacts to the regional water supply. This project is ongoing.ĭistrict-driven projects that benefit regional stakeholders have also been supported by the Responses to Climate Change Program. This effort complements Reclamations Climate Literature Synthesis product by addressing smaller geographic scales and by extending coverage to the entire country. Additional information on this program can be found on the climate change adaptation pilot studies web page.Ĭlimate Change by Hydrologic Unit Code Project provides a detailed summary of the primary literature for major river basins in the United States, including Alaska and Hawaii. In addition, these projects allowed District and HQUSACE staff to engage local and regional stakeholders on the issues of climate change impacts and adaptation. These projects examined the impacts of sea level rise, and coastal and inland flooding on USACE dams and levees, ecosystem restoration features, and water supply across the nation. A total of 15 projects were supported during fiscal years 2010 through 2012. ![]() Pilots and Demonstrations Program, which provided support for Districts to tackle climate change issues within major river basins. These assessments have been conducted under a number of programs and include: Regional to Local Scale Adaptation Pilots These include the regional assessments prepared for the National Climate Assessment, assessments prepared by other Federal agencies, information developed for the USACE climate change adaptation pilot studies, and specifically-tailored information for certain watersheds. Until these regional syntheses are ready, USACE staff can consider regional climate impact assessments that have been developed from a number of different sources for a variety of audiences. These regional syntheses will address issues of interest to USACE Civil Works business lines. USACE will be developing regional climate change literature syntheses at the 2-digit hydrologic unit code (HUC 2) level, a watershed scale suited to the size of USACE Divisions. USACE requires regional assessments tailored to our specific missions to address issues of critical interest to USACE and its stakeholders. ![]() Regional climate impact assessments have been developed from a number of different sources for a variety of audiences. We need consistent information about observed climate trends, projected climate changes and impacts at the watershed scale to support USACE climate change adaptation. ![]() The effects of climate change vary over both space and time, and in a country as large as the United States, these changes can be significant.
