The extreme heat in Phoenix poses significant risks to public health, infrastructure, and daily life. Prolonged high temperatures can lead to heat-related illnesses, strain power grids, and disrupt outdoor activities. Vulnerable populations, such as the elderly and those without access to air conditioning, are particularly at risk. Rare winter freezes, while infrequent, can damage crops, cause frost on roads, and lead to school closures. The urban heat island effect further intensifies the heat in the city, making it hotter than surrounding rural areas. As climate change drives more intense and frequent heat waves, the challenges of managing these extremes are expected to grow.
