This article, jointly authored by ICF International and others, assesses the current state of knowledge on the magnitude of adaptation cost in the United States. While incomplete, the studies suggest that adaptation cost could be as high as hundreds of billions of dollars annually by mid-century.

The article also identifies key studies in each sector, surveys the cost estimates and approaches to cost estimation, and highlights methodological issues in interpreting, comparing, and aggregating adaptation cost estimates. Steps are recommended to make future adaptation cost studies more comparable within and across sectors and more accessible and relevant to policy and decision makers.
