Excessively high temperatures refer to heat levels that significantly exceed normal or comfortable ranges. These temperatures can lead to heat-related illnesses, such as heat exhaustion and heat stroke, especially in vulnerable populations like the elderly and young children. Such extreme heat can also impact the environment, causing droughts and wildfires. In urban areas, the phenomenon known as the urban heat island effect can exacerbate these conditions, where cities become significantly warmer than surrounding rural areas due to human activities and infrastructure.
