Heatwaves
For cities, the heat is on
Today, around 200 million city-dwellers in over 350 cities live with summer temperatures highs of over 35°C (95°F). Even at this level of exposure, heatwaves are the deadliest of all climate risks. By 2050 around 970 cities will be at least this hot, with much higher exposure in Asia, Africa, and North America (see Figure 1). Average high temperatures of 35°C (95°F) will mean that heatwaves will become far more intense.
