Ports are deeply interconnected with inland areas through the goods imported and
exported each year. Climate change impacts on ports can thus have far-reaching implications for
the nation’s economy. These maps show the exports and imports in 2010 (in tons/year) and
freight flows (in trucks per day) from four major U.S. ports to other U.S. areas designated in the
U.S. Department of Transportation’s Freight Analysis Framework (FAF): Los Angeles, Houston,
New York/New Jersey, and Seattle. Note: Highway Link Flow less than 5 FAF Trucks/Day are not
shown. (Figure source: U.S. Department of Transportation, Federal Highway Administration,
