Trees can lower neighborhood temperatures in three ways: 1) Their shade prevents solar radiation from hitting paved surfaces like concrete and asphalt, which absorb energy and rerelease it into the air as heat. 2) Their leaves pull heat from the immediate area in order to evapotranspirate water that’s drawn from the soil. And, 3) If you’re standing under one, a tree protects your body directly from the sun’s rays. If you’ve ever made a summer visit to a dry, hot city like Phoenix, you’ll know how important shade is for making any outdoor experiences tolerable. As Phoenix deals with a rising frequency of extreme heat waves — which aren’t only deadly, but also cause worrisome spikes in energy demand — the city is looking to trees as part of its heat mitigation strategy. Phoenix isn’t devoid of trees, but they’re distributed unevenly across the city. A quick glance at a satellite image of the metro area reveals substantial green splotches in the north and east and brown ones in the south and west, where many lower-income neighborhoods are located. So Phoenix recently pledged to reach “tree equity” by 2030, under an agreement with American Forests, a national tree organization. I visited Phoenix recently to take a look at the current state of the city’s urban forest. In this video, we use drone imagery and thermal cameras to understand how the urban design of the city contributes to extreme heat, and what it can do to cool down. This is the first video of five videos we're releasing on climate change.
