Visitors to the Oklahoma City National Memorial walk around the "Survivor Tree," a 100-year-old American elm and symbol of hope after the deadly 1995 bombing, Friday, April 19, 2019, in Oklahoma City. Science and technology are helping Oklahoma City to sustain the DNA of the tree symbolizing hope 24 years after the deadliest act of domestic terrorism on U.S. soil. As part of an annual remembrance of the bombing, civic leaders on Friday plan to transplant a tree that was cloned from the scarred American elm that lived through the blast. They hope the younger elm will replace the "Survivor Tree" once it dies. (AP Photo/Adam Kealoha Causey)

Phoenix officials say they are tackling urban warming, monitoring downtown temperatures, planting thousands of trees and capturing rainwater to cool off public spaces. (AP Photo/Matt York)
