The heat is on to cool down our cities
RECENT droughts and bushfires have made us far more conscious of how a warming climate can affect our health, especially in regional Australia.
Far less appreciated, however, are the more direct impacts of heat.
The vast preponderance of heat-related deaths and illness will occur not in rural but in urban areas, in part because that is where nearly 90% of us live.
In addition, cities are hotter due to their design.1
This is known as the urban heat island effect and can lead to city temperatures several degrees higher during the day and up to 10 degrees higher at night.
