From the Document: "Between fiscal years 2015 and 2021, selected appropriations for disaster assistance totaled $315 billion. Disaster costs are projected to increase as certain extreme weather events like drought or extreme rainfall become more frequent and intense because of climate change, according to the U.S. Global Change Research Program and the National Academies of Sciences, Engineering, and Medicine. 'Limiting the Federal Government's Fiscal Exposure by Better Managing Climate Change Risks' [hyperlink] has been on GAO's [Government Accountability Office's] High Risk List since 2013. This list identifies government operations that, among other things, need transformation to address effectiveness challenges. Managing climate change is on the list in part because of concerns about the increasing costs of disaster response and recovery efforts. We identified five areas in which government-wide action is needed to reduce federal fiscal exposure to climate change. These areas include the federal government's roles as (1) insurer of property and crops, (2) provider of disaster aid, (3) owner or operator of infrastructure, (4) leader of a strategic plan to coordinate federal efforts, and (5) provider of data and technical assistance to decision makers. Federal fiscal exposure to climate change can be limited by enhancing climate resilience--that is, taking actions to reduce potential future losses by planning and preparing for potential climate hazards."
