Since the early 2020s, local governments around the world have been appointing chief heat officers (CHOs) in response to the increasing cases of heat waves. A CHO’s role is to specifically address the dangers of extreme heat in urban areas. Many cities are particularly at risk due to the urban heat island effect, which is a phenomenon where cities are noticeably hotter than surrounding rural areas. This effect is caused by a lack of green spaces and the heavy use of heat-absorbing materials such as concrete and asphalt. The CHO is tasked with carrying out policies that reduce extreme heat and providing resources to protect people from the risks of heat exposure.
自 2020 年代初期，全球各地的地方政府已開始任命高溫長，以應對日益增多的熱浪事件。高溫長的角色是專門處理都市地區的極端高溫所帶來的危害。許多城市因都市熱島效應尤其容易處於危險之中，其為一種都市的溫度明顯高於周圍農村地區的現象。這一效應是由於綠地稀少，且大量使用混凝土和瀝青等吸熱材料所導致的。高溫長獲指派要執行旨在減輕極端高溫的政策，並提供資源以保護民眾免受高溫暴露危害。
