Planners in Las Vegas say they're working to reduce rising temperatures in a city where paved areas create a warmer environment than plant-covered or rural desert areas. The Las Vegas Sun reports that a panel on Oct. 15, 2019, considered a recent Urban Land Institute finding that Las Vegas is the most intense "urban heat island" in the U.S. That's after another group reported in April that average temperatures in Las Vegas have risen faster than any other city since 1970.
