The article explores how cities get really hot because of all the concrete and buildings. This is called the Urban Heat Island effect. The goal is to learn more about how cities being hot impacts people living there. By comparing city temperatures to rural areas, the researchers found that cities are much warmer, making it uncomfortable for people outside. They studied how urbanization, where more people move to cities, causes this heat problem. This research helps show how cities can get too hot and why it's important to think about making cities cooler for everyone's comfort.
