These psychedelic images reveal what your weather app isn’t telling you

Your weather app is lying to you. According to Grist, Portland State professor Vivek Shandas used thermal imaging to reveal the gap: artificial turf on a college field reached one hundred fifty degrees, while natural grass stayed at one hundred degrees, and downtown pavement climbed to one hundred thirty degrees or higher. But here's the deeper story—these temperature gaps aren't random. Lower-income neighborhoods with few trees and wide roads bake all day, while leafy residential areas stay cooler. During a heat wave, Shandas recorded a twenty-five-degree difference between neighborhoods. Fixing this requires mixing approaches: planting trees, painting roofs white, and adding shade to bus stops. As heat waves intensify, that gap widens, and neighborhoods already struggling without air conditioning suffer most.
