More trees are the answer to cool down our cities

Urban life can be an insulated existence, consisting of circling between one temperature-controlled space after another. But cities are not invulnerable to climatic changes. Indeed, when it comes to heat, they can fare worse. They are also far from homogenous. Counter to the images of “domed cities” that Buckminster Fuller proposed for Manhattan in the 1960s and that Dubai is touted to be pursuing, cities do not have equally distributed temperatures. Even if they do, the risk those temperatures represent are far from equally perceived or experienced.

occur on greenfield sites where one of the first steps

Australians typically pride themselves on being pretty sanguine about the nation’s extreme weather, at least when it comes to spectacular events like Dorothea Mackellar-esque “flooding rains” or disasters playing out elsewhere on our vast continent. But this week even our assumed role as the world’s most variable climate took a turn for the worse, as Australia hosted the planet’s 15 hottest sites. Many of these extreme temperatures were recorded inland in small settlements. Port Augusta, for example, with 15,000 residents, was number two on the list at 49C. Nonetheless, the heat wave rolled across the continent affecting major urban settlements such as Canberra and Western Sydney.
