Fig. 2: Projection of flood insurance claims and policy purchases under higher emissions scenario (SSP585).

a Map showing the predicted cumulative flood loss for 2021–2100 across the coastal CONUS census tracts under climate change emission scenario SSP585. b Average annual flood loss claims expressed as a percentage of housing value across the CONUS coast for the observed period, projected under SSP585 until mid-century (2021–2050), and until the end of the century (2051–2100). c same as (b) for annual average flood insurance policy purchases expressed as a percentage of housing units (d) ratio of (b) and (c). The error bar represents standard error.
