As Australia heads into an El Nino summer, making cities cooler places to live becomes an increasingly pressing problem. How can we manage urban heat and care for the people living here?

Urban climatologist Dr Negin Nazarian spoke to James Murray on The Daily. She explains why cities are hotter than other environments and what can be done to make soaring temperatures more liveable.
Dr Nazarian is a Scientia Senior Lecturer at UNSW Built Environment, and Fellow at the City Futures Research Centre.
