“This report reviews current actions (as of January 2015) of selected federal departments and agencies to adapt their own missions, infrastructure, operations, and personnel to projected climate change. (It does not address federal programs meant primarily to assist others to adapt, although the boundary is often hard to delineate.) This synthesis is not comprehensive. It identifies common approaches among agencies, examples of specific actions, and notable barriers the federal government faces. As of December 2014, almost 40 federal departments and agencies had, to varying degrees, produced climate change adaptation plans, climate change vulnerability assessments, adaptation milestones, and/or metrics to evaluate adaptation performance. These efforts have identified wide-ranging vulnerabilities to potential climate changes, as well as some opportunities. Most agencies are in formative stages of their assessments and strategic planning. Some agencies are embarking on more detailed analyses and limited implementation actions. Overall, few examples are apparent of day-to-day agency decisions or actions that are different as a result of their adaptation efforts. Numerous challenges face federal officials in their efforts, including constrained resources, data gaps regarding location-specific climate changes or existing facilities, insufficient personnel training, and—sometimes—low priority among priorities. CRS identified few on-the-ground adaptations and few evaluations, as yet, of the effectiveness and efficiency of alternative adaptation approaches and actions. It may not be possible to tally budgetary resources associated with federal adaptation efforts. While some are reported in the President’s budget proposals, many are indivisible from the activities with which they are associated, reflecting more of a change in how efforts are undertaken than a change in level of effort.”
