‘We need more shade’: US’s hottest city turns to trees to cool those most in need

Phoenix broke several heat records last year. Now Grant Park, which has inequitable tree cover, is seeing a tree-planting drive that promises some respite from 100F temperatures

It was a relatively cool spring day in Phoenix, Arizona, as a tree-planting crew dug large holes in one of the desert city's hottest and least shaded neighborhoods.

Still, it was sweaty backbreaking work as they carefully positioned, watered and staked a 10ft tall Blue palo verde and Chilean mesquite in opposite corners of resident Ana Cordoba's dusty unshaded backyard.
