In 2013, the Government Accountability Office (GAO) identified the changing climate (see Text Box below) as one of the 30 most significant risks facing the federal government. President Obama established adaptation as a prominent part of his Climate Action Plan, released in June 2013. The November 2013 Executive Order 13653, Preparing the United States for the Impacts of Climate Change , continued the Administration's focus on federal climate change preparedness through agency and department adaptation planning. As of December 2014, more than 30 federal departments and agencies had, to varying degrees, produced climate change adaptation plans, vulnerability assessments, adaptation milestones, or adaptation performance metrics to address the potential vulnerabilities of their missions, property, operations, and/or personnel to climate change. Agency efforts identified wide-ranging vulnerabilities that could result from climate changes, as well as some opportunities. This report is not comprehensive. They are not dramatically different from updated modeling. Some instances of mainstreaming adaptation efforts in agencies are identified in a later section of this report. Synthesis of Agency Adaptation Plans and Example Actions

			Almost 40 Federal Agencies Have Identified Adaptation Efforts

As of December 1, 2014, 38 federal departments and agencies had produced
initial (2012) Climate Change Adaptation Plans and, in most cases, second-round (2014) Plans; vulnerability assessments; adaptation plans with milestones; and/or metrics to evaluate adaptation performance. Agencies Are Adopting Common Approaches

CRS found that federal agencies are largely using a set of common approaches in their climate change adaptation efforts. Current budget constraints and federal budget scrutiny may not permit greater financial resources for federal adaptation actions. While the President's FY2016 budget request and other recent announcements (e.g., executive order on flooding and proposed FEMA rules) may mention adaptation (or "resilience") to climate change, most pertain to programs outside the narrow scope of this report: assessments and actions that agencies may be undertaking to address potential risks to their missions, property, operations, and personnel . For further detail or updates on climate change adaptation plans by individual agencies, the report provides contact information for CRS analysts at the end of each agency section in Part II. Some agencies are also tackling this access problem. The ability of organizations to take advantage of climate change-related information is also critical. Uncertainty

Planning and decision making in the face of uncertainty are a challenge in many fields. Congress may consider the following:
reviewing the significance and nature of the climate change risks to the federal government (including the distribution and timing of those risks); evaluating which, if any, preparations and adaptations are cost-beneficial and feasible; and assessing whether to alter specific agencies' existing authorities. Congress may act to provide federal agencies direction on whether and how adaptation efforts are to be organized and funded, and their performance measured and evaluated (e.g., effectiveness at reducing damage to property, lives, and habitat relative to the federal and private investment of an adaptation measure). Congress may consider the role, costs, and benefits of adapting federal agencies to projected climate change. 2. Analyzing the array of policy documents noted above, FEMA has committed to fulfilling a broad set of actions related to climate change adaptation, such as (but not limited to)
increasing its internal training and communications for FEMA emergency management staff on the connections between climate change and emergency management programs and functions; improving its existing cost-benefit analysis methods for post-disaster assistance programs provided through the Stafford Act, such as the Public Assistance and Hazard Mitigation Grant Program, to incorporate future flood risks (e.g., sea-level rise) and other climate factors; updating risk assessment models that FEMA currently provides to accurately account for possible increases in risk due to climate change, including the Threat Hazard Identification Risk Assessment; and advance and participate in intergovernmental and "whole of community" partnerships to address specific extreme weather events that may increase in frequency and intensity with climate change, such as through the National Cohesive Wildland Fire Management Strategy and the National Drought Resilience Partnerships. More detailed examples are discussed below in the individual summaries of agency climate adaptation plans.
Though Congress has debated the significance of global climate change and what federal policies, if any, should address them, the Government Accountability Office (GAO) since 2013 has identified the changing climate as one of the 30 most significant risks facing the federal government. President Obama established adaptation as a prominent part of his Climate Action Plan in June 2013. The November 2013 Executive Order 13653, Preparing the United States for the Impacts of Climate Change, directed agencies to undertake vulnerability assessments and planning for adaptation. The Administration aimed efforts at reducing agencies' own risks, taking advantage of "no-regrets" adaptation opportunities, and actions that promote resilience to climate changes.
Scope of Report
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.
Role of Congress
In light of agencies' risk assessments and adaptation planning, Congress may consider whether agencies have appropriate statutory authorities to take various climate change adaptation actions; how to make data pertinent to adaptation more accessible and usable by federal agencies and the public; the appropriate priority for federal adaptation efforts in the context of agency missions and budgetary constraints; and timeliness of activities. Congress may provide federal agencies direction on how they should organize and fund their adaptation efforts; whether and how to measure and evaluate program performance (e.g., effectiveness at reducing risks to property, lives, and habitats relative to the federal and private investment of an adaptation measure); and desirable reporting and accountability to Congress and the public. Congress also may assess the role, costs, benefits, and timing of adaptation in the context of discussions regarding climate change mitigation and other broad policy fields such as natural disaster, infrastructure, energy, environmental, agricultural, federal lands, defense, health, tax, and budget policies.
The President's FY2016 budget request and other related administrative announcements roughly concurrent with its release on February 2, 2015, are not addressed in this report. While the President's FY2016 budget request and other recent announcements (e.g., executive order on flooding and proposed FEMA rules) may mention adaptation (or "resilience") to climate change, most pertain to programs outside the narrow scope of this report: assessments and actions that agencies may be undertaking to address potential risks to their missions, property, operations, and personnel. For further detail or updates on climate change adaptation plans by individual agencies, the report provides contact information for CRS analysts at the end of each agency section in Part II.
