Carbon Brief on Instagram: "🔥 Heatwaves around the world are becoming more frequent and intense because of human-caused warming. They are made even more severe in cities by the urban heat island (UHI) effect, which traps heat in urban areas, due to urban infrastructure such as: 🏙️ closely packed buildings 🌆 heat-absorbing surfaces such as concrete 🚘 human activity such as driving cars Cooler air from surrounding rural areas can reduce a city’s temperature by more than 0.5C if land cover is optimised, a new study has found, giving recommendations such as: 🔗 joining up patches of rural land 🌳 planting more woodland 💧 having fewer, bigger lakes Higher urban temperatures lead to a “heat dome” forming over a city, illustrated in the diagram above. The diagram shows how colder air (blue) from the neighbouring rural areas circulates into the urban centre, exchanging with the hotter air (red).
