An aerial view of the Columbia River and the cable and blue bridges that span it and link the cities of Kennewick and Pasco in Washington state. Scientific models predict that rising temperatures will reduce the snowpack and glacier mass in nearby mountains, resulting in less water for the 1,243-mile-long Columbia River. (Tri-City Herald/MCT)
