The map shows median estimates of economic damage per year in 2080 to 2099 under a high-emissions scenario (RCP8.5). Damage is calculated as a percentage of county G.D.P., factoring in agriculture, mortality, crime, labor productivity, coastal impacts and energy demand. Counties with negative damage (green) are projected to see economic benefits. In the chart, the ranges labeled “likely” refer to outcomes with a two-thirds chance of occurring.
