00:00Cities are getting hotter as pavement, buildings, and limited shade intensify summer heat.
00:05About 80% of the U.S. population lives in urban areas.
00:09Heat is also the deadliest weather-related hazard in the United States on average.
00:13Climate Central studied 243 U.S. locations from 1970 through 2025.
00:19Summer temperatures rose by an average 2.6 degrees Fahrenheit in 236 locations.
00:25In the West, Boise and El Paso each warmed by 6.3 degrees.
00:30Las Vegas warmed 6.2 degrees, while Salt Lake City rose 6 degrees.
00:35Pavement and buildings absorb sunlight and release heat into surrounding air.
00:39This creates the urban heat island effect, making cities hotter than nearby rural areas.
00:44Phoenix has neighborhoods where development makes temperatures at least 9 degrees hotter.
00:49Experts say trees can provide major cooling by creating shade and releasing moisture.
00:54Chicago planted trees in neighborhoods with less shade through its Our Roots initiative.
00:59By November 2025, the city had reached 90% of its 75,000-tree goal.
01:05Cities are also testing reflective pavement and cooler roofs to reduce heat absorption.
01:10As summers warm, better shade.
01:13Trees and urban planning could make daily travel safer.
