2 days agoHow cities can keep their cool
Record-breaking heat is now routine. The devastating heatwave that wracked southwestern Europe in 2003 and claimed more than 70,000 lives produced temperatures not experienced in the region since the sixteenth century. Subsequent summers have extended this trend. In 2024, the continent recorded its hottest summer on record. In urban environments, where most of the world's population lives, the problem is especially acute. "If you build a city, inevitably it will be hotter," says Edward Ng, an architect at the Chinese University of Hong Kong.
