Maps showing forecasted environmental changes in Chesapeake Bay Watershed by 2090

The maps show catchment-scale changes in 2090 relative to 2005 values for differing scenarios of temperature (a-c), precipitation (d-f), and land-use (LU; g-h). For each variable, colors show percentiles of low (≤ 25.0%), moderate (25.0-50.0%), and high (≥ 75.0%) change calculated among all scenarios. Inset boxplots for each map illustrate the distribution (median and interquartile range; IQR) of catchment-scale changes summarized by ecoregion (CPL = Coastal Plains, PIED = Piedmont, SAP = Southern Appalachian, NAP = Northern Appalachian). Temperature scenarios are (coolest – warmest) a) 25th percentile among Representative Concentration Pathways, b) 50th percentile, and c) 75th percentile. Precipitation scenarios are (wettest - driest) a) 75th percentile, b) 50th percentile, and c) 25th percentile. Developed LU scenarios from the Special Report on Emissions Scenarios are a) B2 (low development), and b) A2 (high development).
