Millions of U.S. children attend schools located in cities disproportionately threatened by the impact of climate change, researchers recently warned.
Climate change is making heat waves more frequent and intense, and dialing up humidity — which can make climates feel even hotter. Cities absorb and re-emit heat from the sun more than natural landscapes, thanks to their highly concentrated buildings, roads and infrastructure. These pockets of heat are known to climate scientists as “heat islands,” resulting in temperatures up to 20 degrees higher for cities and their inhabitants.
