Projected Damages and Potential for Risk Reduction by Sector

Figure 29.2

U.S. Environmental Protection Agency
Jeremy Martinich

This figure appears in chapter 29 of the Impacts, Risks, and Adaptation in the United States: The Fourth National Climate Assessment, Volume II report.

The total area of each circle represents the projected annual economic damages (in 2015 dollars) under a higher scenario (RCP8.5) in 2090 relative to a no-change scenario. The decrease in damages under a lower scenario (RCP4.5) compared to RCP8.5 is shown in the lighter-shaded area of each circle. Where applicable, sectoral results assume population change over time, which in the case of winter recreation leads to positive effects under RCP4.5, as increased visitors outweigh climate losses. Importantly, many sectoral damages from climate change are not included here, and many of the reported results represent only partial valuations of the total physical damages. See EPA 2017 for ranges surrounding the central estimates presented in the figure; results assume limited or no adaptation.0b30f1ab-e4c4-4837-aa8b-0e19faccdb94 Adaptation was shown to reduce overall damages in sectors identified with the diamond symbol but was not directly modeled in, or relevant to, all sectors. Asterisks denote sectors with annual damages that may not be visible at the given scale. Only one impact (wildfire) shows very small positive effects, owing to projected landscape-scale shifts to vegetation with longer fire return intervals (see Ch. 6: Forests for a discussion on the weight of evidence regarding projections of future wildfire activity). The interactive version of this figure includes value ranges for both the projected damages under RCP8.5 and the projected percentage of avoided damages under RCP4.5.
